1 Nature Society (Singapore) Conservation Committee Report on the Singapore Tourism Board (STB) Project at Mandai (This document is endorsed by the Council of The Nature Society) Preface to Nature Society’s 2007 Report on the Mandai Lake Road Development Nature Society (NSS) had submitted a feedback report on the projected development to Singapore Tourism Board (STB) and National Parks (NParks) in 2007 when the plan was first announced. We were invited to a meeting at that time to be briefed on their plans and to get our verbal feedback. The Orchid Garden at the edge of the Night Safari area was at that time not in the plan for the development. Although submitted in 2007, NSS’ concerns still hold today. At that meeting, we were told that they will be using the project areas to lure and benefit visitors to the Zoo and to effect more than a daily visit. The plan was to create a resort with accommodation on an ecologically sustainable framework so that these visitors could have a few days and nights imbibing the jungle atmosphere of the Zoo’s environs apart from just seeing captive animals. They talked about having natureoriented recreational facilities as well as educational activities. There was no mention about extending the Night Safari nor any mention of transferring the Bird Park from Jurong to any of the state lands at Mandai Lake Road highprofile suggested uses that were reported recently in the mass media. These suggestions (Safari extension & Bird Park) if carried out will pose a serious threat to the integrity of the Central Catchment Nature Reserves (CCNR). Pertaining to these suggestions, there are three major issues of ecological concern: 1) Importance of the Project Areas as Buffer Zone: The nonofficial buffer for the northern sector of the CCNR, east & west of the Mandai Lake Road, will be seriously jeopardized. The northern sector of CCNR is already in bad shape being extremely fragmented. The buffer here consists of the greenery or forested state lands east & west of the Mandai Lake Road as well as the forested MINDEF area to the west of Mandai Track 15. (Track 15 is no longer on the map; it runs in from Mandai Lake Road, at the military gate, to the MINDEF Firing Range.) Within the state land to the west of Mandai Lake Road is an elongated grassy patch with patches of

Preface  to  Nature  Society’s  2007  Report  on  the  Mandai  Lake  Road  Development  

Nature   Society   (NSS)   had   submitted   a   feedback   report   on   the   projected   development  to  Singapore   Tourism  Board   (STB)   and  National   Parks   (NParks)   in   2007  when   the   plan  was   first  announced.  We  were  invited  to  a  meeting  at  that  time  -­‐-­‐-­‐-­‐  to  be  briefed  on  their  plans  and  to  get  our   verbal   feedback.   The  Orchid  Garden  at   the  edge  of   the  Night   Safari   area  was  at   that  time  not  in  the  plan  for  the  development.  Although  submitted  in  2007,  NSS’  concerns  still  hold  today.            

At   that  meeting,   we  were   told   that   they  will   be   using   the   project   areas   to   lure   and   benefit  visitors   to   the  Zoo  and  to  effect  more   than  a  daily  visit.  The  plan  was   to  create  a   resort  with  accommodation  on  an  ecologically   sustainable   framework   so   that   these  visitors   could  have  a  few  days  and  nights   imbibing   the   jungle  atmosphere  of   the  Zoo’s  environs   -­‐-­‐-­‐  apart   from   just  seeing  captive  animals.  They  talked  about  having  nature-­‐oriented  recreational  facilities  as  well  as   educational   activities.   There   was   no   mention   about   extending   the   Night   Safari   nor   any  mention  of  transferring  the  Bird  Park  from  Jurong  to  any  of  the  state  lands  at  Mandai  Lake  Road  -­‐-­‐-­‐  high-­‐profile  suggested  uses  that  were  reported  recently  in  the  mass  media.        

These  suggestions  (Safari  extension  &  Bird  Park)  if  carried  out  will  pose  a  serious  threat  to  the  integrity   of   the   Central   Catchment   Nature   Reserves   (CCNR).   Pertaining   to   these   suggestions,  there  are  three  major  issues  of  ecological  concern:          

1)   Importance  of   the  Project  Areas  as  Buffer   Zone:      The  non-­‐official   buffer   for   the  northern  sector  of   the  CCNR,  east  &  west  of   the  Mandai   Lake  Road,  will   be   seriously   jeopardized.   The  northern  sector  of  CCNR  is  already  in  bad  shape  being  extremely  fragmented.    The  buffer  here  consists  of  the  greenery  or  forested  state  lands  east  &  west  of  the  Mandai  Lake  Road  as  well  as  the  forested  MINDEF  area  to  the  west  of  Mandai  Track  15.  (Track  15  is  no  longer  on  the  map;  it  runs  in  from  Mandai  Lake  Road,  at  the  military  gate,  to  the  MINDEF  Firing  Range.)    Within  the  state   land   to   the   west   of   Mandai   Lake   Road   is   an   elongated   grassy   patch   with   patches   of

secondary   forest   at   the   edges.   The   state   land   to   the   east   of   Mandai   Lake   Road  consists   of  phased-­‐out   orchard   land   now   densely   wooded   with   wild   trees   and   undergrowth,   and   is  contiguous  to  the  nature  reserve  at  the  sector  to  the  east  of  the  Road,  (which  is  shaped  like  a  triangle   with   the   apex   jutting   into   Upper   Seletar   Reservoir).   There   are   many   roles   to   an  ecological  buffer,  but  one  of  these  in  relation  to  the  area  of  our  concern  is  the  role  of  buffer  against  wind-­‐throw,  a  violent  example  of  which  was  seen  in  the  wind-­‐throw  several  years  ago  in  the  CCNR  sector  north  of  the  Upper  Seletar  Reservoir,  which  is  very  close  to  the  area  of  our  concern.   The  wrecking  did  not   reach   the   forest   immediately   to   the  east  &  west  of  Mandai  Lake  Road,  but  who  knows  what  a   similar   event  or   a  more  violent  one  may  do   if   it   occurs  again  -­‐-­‐-­‐  especially  when  the  existing  forest  here  are  thinned  or  wiped  out  by  development.  

2)  Importance  of  the  Project  Areas  as  Wildlife  Corridor      The  areas,  east  &  west  of  the  Mandai  Lake  Road,  as  a  whole  serve  as  a  green  corridor  for  wildlife  movement  from  the  north-­‐western  sector  to  the  north-­‐eastern  sector  of  the  CCNR  (including  the  isolated  nature  reserve  area  north  of  Mandai  Road)  and  vice  versa  -­‐-­‐-­‐  across  Mandai  Lake  Road.  The  opening  up  of  these  areas  for  extensive   development   will   seriously   jeopardized   this   existing   green   corridor.    There   are   of  course   many   ecological   impacts   that   can   be   mentioned,   but   if   they   are   going   to   have   an  extension  of  the  Night  Safari  into  the  area  and  a  Bird  Park  (most  probably  a  larger  one)  ,  one  serious  problem  will  come  with    the  erection  of  extensive  fences.  Right  now,  the  Night  Safari  has  an  extensive   fence  around   it   except   for   the   shoreline,  and   if   extended   further   into   the  state   land,   will   definitely   constrained  more   adversely   the  movement   of   wildlife   along   this  existing  green  corridor.  The  same  situation  will  apply  to  the  creation  of  a  Bird  Park,  which  will  involve  clearing  or  thinning  of  the  forest    and  more  fences,  especially  with  the  creation  of  a  large    flight-­‐in  aviary  like  that  in  the  existing  Bird  Park  or  a  larger  one.    

3)  The  Importance  of  the  Project  Areas  themselves  as  Biodiversity-­‐Rich  Nature  Areas.  This   is  highlighted  by  a  biodiversity   survey  commissioned  by  STB  around  2006/2007.   It   is  heartening  that   the   authorities   had   announced   in   the  public  media   that   there  will   be   an   EIA,  which  will  have   a   wider   scope   than   a   biodiversity   impact   assessment   (BIA)   or   survey.   The  recommendation  of  the  STB’s  BIA  (2007)  is  best  to  leave  the  projected  areas  for  development  untouched   because   of   the   richness   of   their   biodiversity,   which   includes   species   like   the  endangered  Sunda  Pangolin,  Grey-­‐headed  Fish  Eagle,  Straw-­‐headed  Bulbul,  etc.  (See  the  NSS  report).   It   is   now   about   7   years   down   the   road   since   that   STB’s   survey  and   since   no  development  has  been  going  on  there  from  that  time,  except  for  some  military  facilities  like  training  shades,  the  greenery  there  has  become  more  mature,  denser,  and  even  grown  larger,  and  as  a  such  they  may  probably  be  richer  in  wildlife  now.  NSS  is  not  just  concerned  with  the  ecological   impact   of   development   into   the   nature   reserve   zone   but   also   the   impact   on   the  existing  wildlife  using  the  areas  outside  and  contiguous  to  the  nature  reserve  as  well  -­‐-­‐-­‐  either

as  nesting/breeding  or  foraging  grounds.  Of  note  is  a  natural  stream  (uncanalised)  to  the  west  of  Mandai  Lake  Road  and  bordered  on  both  banks  by  belts  of  trees,  running  right  through  the  project  area  from  the  nature  reserve.  Aquatic/semi-­‐aquatic  life-­‐forms,  some  of  them  typical  of  wooded  streams,  will  be  adversely  affected  by  development.

I)  Introduction  

  This  report  is  formulated  based  on  information  provided  by  STB  in  two  meetings  on  an  eco-­‐tourism  project  south  of  the  Mandai  Road  area  and  on  both  sides  of  the  Mandai  Lake  Road.  In  these  meetings  we  gather  that  STB  is  looking  at  two  parcels  of  land  contiguous  to  the  Central  Catchment  Reserve  and  these  are:          

1)  Mandai  Road  Patch:   An  wedge-­‐shape  patch  of   about  15  ha   -­‐-­‐-­‐   bounded  by  Mandai  Road,    Mandai  Lake  Road  and  the  boundary  of  the  Western  Catchment  Reserve;  and  

2)  Mandai  Track-­‐15  Patch:  An  elongated  patch  of  about  18  ha  -­‐-­‐-­‐  between  Mandai  Track  15  and  the  Western  Catchment  Reserve  up  to  the  military  firing  range.    

  The   total   comes   to   about   33   ha   -­‐-­‐-­‐   all   of   which   are   contiguous   to   but   outside   the  boundary  of  the  Nature  Reserve.  

  STB  has  not  provided  any  detailed  plans  for  the  use  of  these  areas  except  that  they  will  be   used   for   tourism   and   that   the   project   will   take   into   account   and   be   sensitive   to   the  biodiversity  and  ecology  of  these  areas.  

  STB  has  carried  a  biodiversity  survey  of  these  areas  and  we  have  been  given  a  summary  of  the  results.  The  results  are  very  impressive  and  together  with  our  field  and  map  study  of  the  area,   we   are   extremely   perturbed   with   the   development   project.   We   have   arrived   at   the  following  conclusions  and  proposals,  which  will  be  spelled  out  below.        

II)  Summary  of  STB’s  Wildlife  Survey  (February  2007)  

  This  is  given  in  the  Executive  Summary  of  the  STB’s  survey  report,  which  states:  “Of  the  selected  faunal  groups,  252  species  of  animals  have  been  recorded  within  the  survey  zone  so  far.  This  involves  18  mammals,  114  birds,  24  reptiles,  15  amphibians,  21  fish,  37  butterflies  and  23   odonates   (damselflies/dragonflies).   A   total   of   55   Locally   Threatened   animal   species   were  recorded   and   this   included   the  Globally   Threatened   Sunda  Pangolin,  Grey-­‐headed   Fish-­‐Eagle,  Red-­‐crowned  Barbet  and  the  Straw-­‐headed  Bulbul.  Of  the  animal  species  recorded,  43  may  be  considered  Forest  Specialists”    

  “The   Seletar   Zone,   despite   its   relative   small   area,   is   an   important   part   of   the   Central  Catchment   Nature   Reserve.   More   than   20%   of   the   animals   recorded   are   considered   Locally  Threatened.  ”                

  We  accept  the  results  of  this  biodiversity  survey  report  and  we  also  agree  totally  with  its  conservation  recommendation,  which  states  that  “it  is  best  to  leave  area  untouched.”

III)  Serious  Concerns  from  a  Wider  Ecological  Framework  

  Our  concerns  do  not  stem  from  merely  on-­‐site  study  of  the  ecological  situation  but  also  from   a   study   of   the   wider   ecological   framework,   covering   the   situation   of   the   Central  Catchment  Reserve  as  a  whole.  This  is  also  to  take  long-­‐term  view  of  the  ecological  health  and  viability  of  the  Reserve  given  the  foreseeable  impacts  of  the  STB’s  project.                      

A)  The  Fragmentation  of  the  Forest  

  Please  refer  to  Google  Map  1  attached.  

    The   forest   is   seriously   in   bad   ecological   shape   due   to   severe   fragmentation   over   the  decades   caused   by   the   creation   of   golf   courses,   roads,   pipelines,   expansion   of   the   existing  reservoirs,  etc.  In  fact,  the  whole  of  the  forest  Nature  Reserve  are  now  fragmented  into  roughly  7  patches,  each  standing  in   isolation  from  the  rest  through  gaps  in  the  forest  cover.  What  we  have  now  is  what  ecologists  call  ‘habitat  islands’  rather  than  one  homogeneous,  integrated  and  compact  forest.  Fragmentation  brings  about  population  isolation  among  the  various  species  as  well  as  the  well-­‐studied  phenomenon  of  the  edge-­‐effects.  These  7  patches  are:  

1)  Bukit  Timah  Forest  -­‐-­‐-­‐-­‐  to  the  west  of  the  BKE;      

2)  MacRitchie  Forest  -­‐-­‐-­‐  bordering  Lornie  Road;    

3)  Peirce  Forest  -­‐-­‐-­‐-­‐  between  Upper/Lower  Peirce  Reservoir  and  MacRitchie  Reservoir;  

4)  Seletar  Forest  -­‐-­‐-­‐  between  Upper/Lower  Peirce  Reservoir  and  Upper  Seletar  Reservoir;  

5)  Mandai  Forest  -­‐-­‐-­‐  south  of  Mandai  Road  to  Upper  Seletar  Reservior;  

6)  Asrama  Forest  -­‐-­‐-­‐  strip  parallel  to  and  north  of  Mandai  Road.    

7)  Mandai  Zoo  &  Night  Safari   -­‐-­‐-­‐  a  degraded  area  within   the  Reserve  and  separated   from  the  rest  of  the  Reserve’s  forest  by  the  Mandai  Lake  Road  and  the  Night  Safari’s  fence.              

  Edge-­‐effects   involves   loss   of   humidity,   loss   of   interior   cooler   habitat,   invasion   and  predation   by   alien   and   non-­‐forest   species,   introduction   of   diseases   from   urban   zones   to   the  forest  wildlife,  which  have  no  immunity  or  resistance  to  them,  etc.    (A  standard  accessible  text  on  this  subject   is  Essentials  of  Conservation  Biology,   in  particular  Part  3,  Ch.  9;  by  Richard  B.  Primack;  Sinauer  Associates.)

B)  Forest  Degradation  

  Apart  from  the  overall  fragmentation,  we  have  further  degradation  within  these  forest  patches  themselves  caused  by  inappropriate  uses,  which  involves  clearance  of  the  forest  cover  within   the   boundary   of   the   Central   Catchment   Reserve   to   a   greater   or   lesser   extent.   Some  prominent  examples  are:    

1)  The  Zoo  and  the  Night  Safari,  which  degraded  about  89  ha  of  compact  forest;      

2)   The   recently-­‐created   huge   covered-­‐reservoir   at   Upper   Peirce,   which   cleared   completely  about  11  ha  of  forest;    

3)  The  Nee  Soon  Firing  Range,  which  cleared  20  ha  of  forest  that  was  a  part  of  the  remaining  rare  swamp-­‐forest  in  Singapore  harbouring  many  rare  and  nationally  endangered  wildlife;          

C)  General  Conclusions  Drawn  

  Given  this  overall  situation,  it  is  indeed  very  alarming  for  the  future  survival  of  our  forest  wildlife.  If  we  are  sensitive  to  the  ecological  dimension  of  the  situation,  we  are  inevitably  led  to  the  conclusion  that:  

1)  There  is  an  urgent  need  to  fill  in  the  gaps  and  to  provide  officially-­‐designated  buffer  areas  for  the  forest  Reserves  that  are  not  subjected  to  future  developments.    So  far  the  setting  up  of  the   Hindhede   Park   (9.5   ha.)   and   the   Dairy   Farm   Park   (63   ha)   by   National   Parks,   both   as  integrated   buffers   to   the   Bukit   Timah   Nature   Reserve,   is   a   move   in   the   right   direction.   The  situation  is  now  more  urgent  on  the  northern  flank  of  the  Central  Catchment  Reserve,  where  the  STB  sites  are  located  -­‐-­‐-­‐  as  the  gaps  there  are  extremely  severe;    

2)  There  should  be  compensation  for  the  development  use  of  the  Reserve  land,  which  for  the  prominent  cases  sited  above  comes  to  about  120  ha.  The  creation  of  Hindhede  Park  and  Dairy  Farm  Park,  both  amounting  to  about  72.5  ha.,  compensates  to  some  extent.                

3)   There   is   an   urgent   need   to   stop   any   more   development   within   and   at   off-­‐boundary  contiguous  areas;    

4)   And   to   incorporate   officially,   as   integrated   buffers   of   the   Central   Catchment   Nature  Reserve,   all   undeveloped  areas  between   its   boundary   and   the   surrounding   roads   -­‐-­‐-­‐  Upper  Thomson,  Mandai,  the  BKE,  and  the  PIE.    The  forest  Nature  Reserves  comes  to  about  only  2000  ha   minus   the   waterbodies   and   this   is   relatively   small   and   fragile   compared   to   other   such  reserves   in  the  region.  Because  of  fragmentation,  the  width  of  many  portions  of  the  forest  at  the   Reserve   boundary   are   extremely   thin   and   lacking   in   interior   habitat.   The   use   of   these

buffers  should  be  like  what  has  been  conceptualized  and  implemented  at  Hindhede  and  Dairy  Farm  where  no  built   structures   are   allowed  apart   from  a   visitor   centres,   hides,   rain-­‐shelters,  etc.   and   also   where   for   example   cycling,   which   are   prohibited   within   the   Reserves,   can   be  allowed  along  designated  routes.      

IV)  STB  Proposed  Development  Areas  

  Refer  to  Google  Map  2  &  3  attached.  

A)  Mandai  Road  Patch  (15  ha)  

  Although  this  patch  is  outside  the  Reserve’s  boundary,  it  is  a  highly  important  unofficial  buffer  to  the  Reserve  on  the  north-­‐western  sector.  The  forest  here  is  secondary  and  very  dense,  comprising  mostly  of  belukar  vegetation   (e.g.  Durian,  Rambutan,   Fish-­‐tail  Palm,  African  Tulip,  etc.)  Many  of   the   trees  are  very  mature  and  over   time   this  patch   can   revert  back   closer  and  closer  to  the  state  of  the  original  forest  through  colonization  by  the  typical  rainforest  species.    

  Society’s   Stand   Here:   We   strongly   urge   that   this   patch   should   be   left   completely  untouched.  Our  reasons  are  as  follows:  

  1)   Refer   to   Google   Map   3.   The   use   of   this   patch   would   cause   a   greater   gap   in   the  connectivity  for  wildlife  between  the  Reserve’s  forest  on  the  eastern  side  of  Mandai  Lake  Road  and   the   remaining   Reserve’s   forest   on   the   western   side   of   the   Road.   Note   that   the   wildlife  connectivity   along   the   Reserve’s   forest   on   the   eastern   side   of   the  Mandai   Lake   Road   has   a  severe   gap   at   the   point   opposite   the   Mandai   Orchid   Garden   and   also   further   down   the  shoreline,   where   the   road   cuts   to   the   very   edge   of   the   Reservoir,   leaving   no   green   corridor  along   the   stretch  here.  Also  note   that   the  presence  of   the   fenced-­‐up  Mandai  Orchid  Garden  together  with  the  fenced-­‐up  Zoo’s  compound  all  the  way  from  the  Garden  to  the  Zoo’s  gate  has  already  posed  an  extremely  severe  obstacle  to  wildlife  connectivity  between  the  forests  on  the  eastern  and  western  side  of  the  Lake  Road.    For  any  wildlife,  e.g.  Pangolin,  Leopard  Cat,  Mouse  Deer,  Sambar  Deer  (an  escapee,  but  originally  native  to  Singapore),  etc.,  to  cross  from  one  side  to  the  other,  they  currently  can  only  to  do  so  by  crossing  the  Lake  Road  in  the  quieter  hours  (at  dawn  or   in   the   night  when   the   traffic   is     negligible)   -­‐-­‐-­‐  but   only   at   the   stretch   between   the  Orchid  Garden  and  Mandai  Track  15.  This   is  a  very  short   stretch.  Crossing  at   the   remaining  stretch  from  Track  15  to  Mandai  Road  is  blocked  by  the  presence  of  the  deep  monsoon  drain  along  the  eastern  side  of  the  Lake  Road.    The  use  of  the  remaining  unofficial  forest  buffers  on  both   sides   of   the   Lake  Road  would   entail   that   this   available   fording-­‐point   (across   the   road  obstacle)  would  become  more  degraded  and  disturbed,  which  most  probably  will  result  in  the  complete  isolation  of  the  wildlife  in  these  forest  fragments.

  2)  The  STB  has  proposed  that   it  will  preserve  the  older  trees  here  as  much  as  possible  but  this  will  degrade  the  buffer  considerably  as  a  forest  ecosystem  or  habitat.  The  result  will  be  a  parkland  landscape,  where  the  variety  of  habitat  niche  in  such  forest,  each  harbouring  its  own  typical  wildlife,  will  be  lost.  As  it  is  with  its  profusion  of  shrubs  and  trees,  it  is  provides  an  extra  foraging  ground  and  habitat  for  many  of  the  Reserve’s  wildlife.  Examples  of  the  wildlife  that  will  be  adversely  affected  with  the  forest  tidied  up  to  a  parkland  habitat  are  all  the  forest  frogs,  bird  species   such   as   the   Chestnut-­‐winged   Babbler,   Rufous-­‐tailed   Tailorbird,   Greater   Coucal,   etc.,  mammals  such  as  the  Mouse  Deer,  Pangolin,  etc.  Moreover,  if  STB  seriously  intends  to  keep  all  the   mature   or   big   trees   standing   here,   then   opening   up   the   buffer   to   create   spaces   for  necessary  structures  here  will  be  very  limited  as  there  are  plenty  of  such  trees  around.  In  this  regard,  it  is  better  to  keep  it  completely  untouched.                                    

  3)  This  area  is  an  important  buffer  with  respect  to  a  pair  of  the  Grey-­‐headed  Fish  Eagle  that  haunts  the  Reserve’s   forest  at  this  corner.  They  fish   in  the  Reservoir  and  resorted  to  the  tall  trees  here  to  eat  their  catch  and  rest  or  roost  in  the  night.    Although  there  is  no  record  so  far   of   their   nesting   here,   it   is   probable   their   nest   is   located   in   the   area.   The   Fish   Eagle   is   a  nationally  rare  and  endangered  species  and  are  limited  in  their  distribution  to  the  large  water-­‐bodies  in  Singapore.  If  this  area  is  used,  the  activities  and  the  noises  that  will   inevitably  occur  will   be   very   disturbing   to   the  pair   and  other  wildlife   here   as  well.   (Canoeing   in   the   reservoir  here  should  be  totally  disallowed.)                  

B)  Mandai  Track  15  Patch  (18  ha)  

  Refer  to  Google  Map  2  &  3  

  The  area  to  be  used  is  on  the  eastern  side  of  Mandai  Track  15  and  also  contiguous  to  the  Reserve’s  boundary.  The  patch  is  less  dense  in  forest  cover  with  open  grassy  patches  closer  to  the  Track,  but  on  the  whole  the  forest  is  in  the  process  of  regenerating  after  the  phasing  out  of  farming  and  villages.  

  Society’s  Stand  Here:  Refer  to  the  Google  Map  3.    Again  we  strongly  urge  that  it  should  be   left   untouched   to   allow   for   the   regeneration  of   the   forest   here   to  provide   a   broader   and  stronger  buffer.  Eco-­‐friendly  development,   if   it   is  properly  done,  could  and  should  be  pushed  more  into  the  Jalan  Kwok  Min  area,  between  Mandai  Track  15  and  the  BKE.  The  reasons  for  this  proposal  are:  

  1)   This   unofficial   buffer   for   the   Reserve   is   pretty   thin   and   there   is   an   urgent   need   to  broaden   it.   The   Orchid   Garden   has   destroyed   a   big   chunk   of   the   buffer   here.   Although  degraded,   the   forest   here   can   recover   over   time   and   this   can   be   accelerated   by   artificial  regeneration  of  the  native  species.  There  is  a  natural  flowing  stream  running  through  the  area  

Page 9: NatureSociety(Singapore) ! ConservationCommittee ... on the STB... · 2014-09-17 · "(See"the"NSS" report)."It is now! about 7 years down t he! road since! that STB’s survey!and

and   such   a   stream   running   through   forested   areas   are   now   very   rare   in   Singapore.   The  regeneration  of  the  forest  cover  here  would  enhance  the  biodiversity  of  the  stream  and  bring  it  back  to  its  original  forest  eco-­‐systemic  condition.  The  use  of  area  for  development  would  entail  that   the   edge-­‐effects   will   increase,   such   as   the   further   increase   in   temperature   and   lost   of  humidity  and  the  resulting  decrease  in  cooler,  shadier  and  quieter  interior  forest  habitat,  which  is  critical  for  shade-­‐loving  plants  and  wildlife  that  prefers  a  cooler  micro-­‐climate,  such  as  forest  amphibians   (e.g.   Copper-­‐cheeked   Frog,   Black-­‐eyed   Litter   Frog),   forest   butterflies   (e.g.   Saturn,  Common  Posy,   Tawny   Palmfly.),   forest   reptiles   (e.g.  Marbled   Forest  Gecko),   forest  mammals  (e.g.  Blyth’s  Horseshoe  Bat),  etc.  Clearing   the  undergrowth  and   leaving   just   the  more  mature  trees  standing  will  not  help  in  alleviating  this  forseeable  degradation.    

  2)   It  will  also  cause   further  degradation  and  disturbance  of   the  only  available   fording-­‐stretch  across   the  road  obstacle   for  wildlife  between  the  Reserve’s   forest  on  the  eastern  and  western  side  of  the  Lake  Road.  The  obstacles  to  wildlife  connectivity  along  the  eastern  side  of  the  Lake  Road  has  been  pointed  in  Section  A  above.  On  this  western  side,  the  existing  obstacles  are  the  Orchid  Garden  and  the  Zoo’s  fence  along  the  Lake  Road,  stretching  from  the  Garden  all  the  way  to  the  Zoo’s  gate.  There  is  also  the  deep  monsoon  drain  stretching  for  about  80m  from  the   entrance   of   Lake   Road   to   the   point   roughly   opposite   the   entrance   of   Track   15.   As   is  emphasized  above,  the  only  available  fording–stretch  across  the  road  is  the  very  short  stretch  from  Track  15   to   the  northern  boundary  of   the  Orchid  Garden.   The   implementation  of   STB’s  project   extending   along   both   sides   of   the   road   would   cause   this   fording-­‐stretch   to   become  extremely   degraded   and   wildlife   connectivity   will   be   seriously   jeopardized   in   this   northern  sector  of  the  Central  Catchment  Reserve.                                                          

C)  Leopard  Cat  (See  the  photo  attached)    

  We  would  like  to  highlight  here  a  very  important  consideration  for  the  Society’s  position  and   argument   presented   above,   and   this   is   the   fact   of   the   presence   of   the   Leopard   Cat  (Prionailurus   bengalensis)   in   the   area.   The   Leopard   Cat   is   a   rare   and   endangered   mammal  species   as   well   as   the   only   wild   cats   extant   in   Singapore,   the   Tiger   and   the   Leopard   being  already  extinct  long  ago.  Moreover,  it  is  a  very  beautiful  animal.    

  Residents  in  the  area  close  to  Track  15  in  the  late  1960s  were  aware  of  a  population  of  Leopard  Cat   in   the  area.   (Information  obtained   from  a  Society’s  member  Mr.Yeo  Suay  Hwee,  who  grew  up  here  and  who  is  also  a  member  of  the  Society’s  Vertebrate  Study  Group.)    Also,  on  11th  June  2001  a  roadkill  Leopard  Cat  was  found  along  the  south  side  of  the  Mandai  Road,  not  far  from  the  junction  with  Mandai  Lake  Road.  It  is  interpreted  here  that  the  animal  was  actually  attempting  to  cross  the  Mandai  Road  either  from  north  to  south,  or  from  south  to  north.  

Page 10: NatureSociety(Singapore) ! ConservationCommittee ... on the STB... · 2014-09-17 · "(See"the"NSS" report)."It is now! about 7 years down t he! road since! that STB’s survey!and

  The  Mandai  area  is  one  of  only  two  known  areas  where  the  species  exists  at  the  margins  of  the  Central  Catchment  Nature  Reserve;  the  other  area  being  the  Watten  Estate  /  Adam  Park  /   Hillcrest   area   where   there   was   a   sighting   on   6th   July   2002,   but   of   course   this   area   is  fragmented  from  the  Central  Catchment  by  the  PIE.  Thus  the  animals  encountered  here  at  the  Mandai  Area  are  the  only  ones  not  totally  fragmented  from  the  Reserve.  The  fact  that  there  is  a  Leopard  Cat  roadkill  here  only  about  6  years  ago  indicates  the  need  of  this  rare  and  endangered  species   as   well   as   other   ground-­‐moving   animals   to   move   and   forage   across   existing   roads,  tracks  and  forest  edges  and  buffers.      

  Any  development  projects  to  be  eco-­‐friendly  must  take  this  point  into  serious  account.  A  highly  important  consideration  for  such  a  development  -­‐-­‐-­‐  especially  when  it  is  contiguous  to  a  Nature   Reserve   -­‐-­‐-­‐   is   to   ensure   that   the   existing   wildlife   connectivity   of   the   forest   is   not  jeopardized.   In   fact,   in  other  developed  countries,   conservation  efforts  and  provisions  will  be  made   to   facilitate   such  connectivity  by   removing   the  obstacles,   closing   the  gaps  and  creating  green  corridors  through  planting  or  natural  regeneration  of  the  degraded  patches.  An  excellent  example  of  such  an  effort   in  Singapore   is   the  MND  project  to  create  an  eco-­‐link  between  the  Bukit  Timah  and  the  Central  Catchment  Reserve  -­‐-­‐-­‐   recently  announced.  More  of  such  efforts  should  be  carried  out.                                                        

  Other  known  populations  are  at  Pulau  Ubin  (exceedingly  rare)  and  Pulau  Tekong  (rare,  and  extremely  localised)  as  well  as  another  roadkill  at  Jalan  Bahar.      

V)  Nature  Society’s  Proposals  

Alternative  1  

  Refer  to  Google  Map  5    

  We  strongly  urge  that  the  whole  project  be  located  elsewhere  -­‐-­‐-­‐-­‐  in  the  beautiful,  semi-­‐natural  areas  of  the  countryside.    A  good  example  of  such  an  area  to  look  at  is  the  undeveloped  area  between  Yio  Chu  Kang  Road  and  the  Lower  Seletar  Reservoir,  where  there  is  a  variety  of  landscape   making   the   area   very   scenic   -­‐-­‐-­‐   woodlands,   scrublands,   marshes   and   a   large  waterbody  (the  Lower  Seletar  Reservoir.)    

  The  main  reason  is  that  this  northern  sector  of  the  Central  Catchment  Reserve  forest  as  well   as   the   unofficial   buffer   areas   around   are   already   rather   in   a   fragmented   and   degraded  state  due   to   the  creation  of  Mandai  Road,   the  Mandai   Lake  Road,   the  Orchid  Garden  and   its  fencing,   the   Zoo   and   its   fencing,   the   military   firing   range,   etc.   This   ecologically   unhealthy  situation  will  be  exacerbated  by  the  STB  project  with  an  additional  influx  of  infrastructures  and  vehicular   traffic,   accompanied   with   more   visitor   activities,   noises   and   lightening   up   of   the  

Page 11: NatureSociety(Singapore) ! ConservationCommittee ... on the STB... · 2014-09-17 · "(See"the"NSS" report)."It is now! about 7 years down t he! road since! that STB’s survey!and

forest.   Thus,  what   is   left   of   the   remaining   undeveloped   areas   outside   the   Reserve   boundary  should  be   left  untouched  and  designated  as  official   buffers,   like  what  has  been  done   for   the  Bukit  Timah  Nature  Reserve  by  the  setting  up  of  the  Hindhede  and  the  Dairy  Farm  Park.  Efforts  should  be  made  to  reforest  the  open  areas  to  strengthen  the  buffers   instead  of  opening  it  up  for  eco-­‐tourism  with  a  residential  dimension.      

  As   to  use  of   these  areas   for  eco-­‐tourism,  we  are   skeptical  of   its  potential   for   success.    Given   that   the   site   is   ecologically   sensitive,   the   onus   is   on   STB   to   show   that   its   project   will  definitely  succeed  to  bring  in  the  targeted  number  of  tourists.  How  certain  is  STB  of  this?    If  the  project   fails   like   what   happens   at   the   Tang   Dynasty   City,   Dragon  World,   etc.,   then   STB   has  caused  a  further  degradation  of  the  forest  here  jeopardizing  the  future  survival  of  the  Reserve’s  wildlife  with  little  to  compensate  in  return.  

  The  whole   of   the   forest  Nature   Reserves,   let   alone   the   30-­‐plus   ha.   area   proposed   by  STB,  is  simply  too  small  and  lacking  in  conspicuous  or  charismatic  species  to  provide  a  basis  for  sustained  eco-­‐tourism  attraction  on  an  international  scale.  The  interesting  mammal  species  to  be  found  there  such  as  the  Leopard  Cat,  the  Pangolin,  the  Mouse  deer,  the  Flying  Lemur,  etc.,  are   all   pretty   small   and   are   difficult   to   spot.   (Please   refer   to   the   Appendix   for   more   of   our  comments  on  this  subject.)  

  However,   a   small   visitor   and/or   field-­‐study   centre   could   be   set   up   here   to   cater   to  researchers,   students,   nature-­‐lovers   and   Zoo   visitors  who  may  be   interested   to   know  and   to  take  up  the  challenge  of  spotting  the  non-­‐captive  native  wildlife  of  our  forest.  The  only  other  such  centre  for  the  Central  Catchment  Reserve  is  located  far  away  on  the  eastern  sector  -­‐-­‐-­‐  off  Upper  Thomson  Road.                                                                

Alternative  2    

  Refer  to  Google  Map  4  

  However,   if   locating   the  project  elsewhere   is  not  possible,  we  strongly  urge   that  both  the  sites  (a  total  of  30-­‐plus  ha)  should  be  located  to  the  west  of  Mandai  Track  15,  at  the  Jalan  Kwok  Min  area   -­‐-­‐-­‐   i.e.  between  Track  15  and  BKE  and  south  of   the  Mandai   Lake  Road   to   the  Firing  Range.      

  The  proposed  alternative  here  has   the  advantage   that   it   is   a   single   site,   and  does  not  have  Mandai   Lake  Road   running   through   it,  with   the   stream  of   cars,   coaches  and  buses.   The  forest  here  is  also  secondary.  There  is  sufficient  space  such  that  given  the  area-­‐size  requirement  (30-­‐plus  ha.),  a  stretch  of   forest  hugging  the  BKE  can  still  be   left  standing,  providing  together  with  the  broad  pipeline  setback  a  comfortable  buffer  and  screen  against  the  BKE.

  As  to  the  degraded  forest  to  the  east  of  Track  15,  STB  should  use  the  opportunity  to  show   its   eco-­‐friendliness   by   implementing   a   planting   programme   as   part   of   the   project.  Nothing   here   should   be   cleared.    What   is  most   important   is   that   the   available   buffer   and  fording-­‐stretch   for   wildlife   traversing   the   Lake   Road   will   be   prevented   from   further  disturbance   and   degradation   and   with   artificial   regeneration   could   over   time   be   made   to  recover  into  healthy  forest.                                                            

  The  area  would  need   to  be  vacated  by  Mindef.  As  a   rather   isolated  and  small  Mindef  site,   it  could  and  should  be  easily   transferable  elsewhere.  The  presence  of   the  military  camp,  training  facilities,  firing  range,  trundling  trucks,  soldiers  moving  around,  etc.,  is  glaringly  out  of  keeping  with  the  idea  of  this  being  an  area  of  nature-­‐themed  attractions.

Appendix   1:     Some   Considerations   on   the   Prospect   of   Improving   the   State   of  Singapore  Tourism    

  At   the  16   January  2007  Meeting  with  STB,   the  Mandai  nature-­‐themed   tourist   venture  was  introduced  as  part  of  the  attempts  by  the  STB  to  achieve  its  present  goals.  These  goals,  set  in   January   2005,   were   to   double   visitor   arrivals   to   17million   and   treble   tourism   receipts   to  $30billion  in  the  ten-­‐year  period  to  2015,  as  well  as  to  increase  the  number  of  employees  in  the  tourism   sector   from   150,000   to   250,000.   The   Nature   Society   (Singapore)   appreciates   the  importance   of   these   goals,   but   note   that   Singapore   has   been   increasing   its   visitor   numbers  satisfactorily  since  2005  without  any  new  attractions  at  all.  Although  the   increases  have  been  less   than  10%  per  year   (7.4%   in  2005,  and  9%   in  2006,  and  may  only  be  around  5%   in  2007),  these   increases   have   occurred   without   the   opening   of   new   attractions.     The   expansion   of  Medical   and   Educational   Tourism   for   instance,   the   continuing   importance   of   Singapore   as   a  centre   for   conferences   and   incentive   groups,   and   the   general   health   of   the   Asian   tourism  market,  have  been  helping  the  tourism  sector  towards  the  STB  goals.      

  In  the  next  few  years  a  great  many  new  projects  will  open,  such  as  the  two  Integrated  Resorts,  the  Marina  Bay  Gardens,  the  F-­‐One  Racing  Circuit,  which  will  catapult  visitor  numbers  towards   the   achievement   of   the   STB   goals.   Even   well   before   the   opening   of   the   Integrated  Resorts,  events  such  as  the  first  night-­‐time  street-­‐circuit  Formula  One  in  September  2008,  will  lead   to  a  massive   increase   in   tourism  for  2008.  The  Marina  Reservoir,   soon  to  be  completed,    will   allow   for   greater   number   of   water-­‐sports-­‐based   events,   set   excitingly   against   the   city  backdrop.    The  proposed  motor  sports  circuit  at  Changi  will  likewise  bring  in  some  international  or   regional   events.   All   of   these   are   likely-­‐winners   in   terms   of   increasing   tourist   numbers,  appealing  to  the  mainly-­‐Asian  tourists  who  come  to  Singapore,  as  well  as  being  commercially  successful  on  the  basis  that  they  will  be  supported  by  Singaporeans.    

  On  the  other  hand,  where  Singapore  has  been   least  successful   in   the  past   is   in  single-­‐themed  attractions.  Although  some  of  them  have  been  successful,  such  as  the  Jurong  Bird  Park,  the  Night   Safari,   the   Zoo   and  Underwater  World,   others   have   been   totally   unsuccessful,   e.g.  Tang  Dynasty   City,   Dragon  World,   Fantasy   Island,   Asian  Village,  Malay   Village.   The   success   is  particularly  unlikely  if  the  ventures  are  not  going  to  pull  in  a  local  clientele.  It  might  be  argued  that,   because   the   Mandai   development   will   be   a   “nature-­‐themed”   attraction,   that   it   would  automatically   be   successful.   However,   the   fact   is   that   the   four   successful   attractions   noted  above   cover   all   the   angles   in   terms   of   fauna-­‐attractions,   and   the   proposed  Mandai   nature-­‐themed  attraction  is  aimed  at  being  a  “general”  nature-­‐themed  attraction  but  in  an  area  that  is  not  one  of  outstanding  natural  beauty  from  a  tourist’s  point  of  view,  or  those  of  a  local  person.  There   are   no   waterfalls,   or   locations   for   canopy   walks.   The   area   is   regenerating,   and   vitally  attractive  to  local  fauna,  but  not  so  to  tourists  or  locals.    The  Mandai  Road  traffic  and  the  traffic  on  Mandai  Lake  Road  will  impinge  on  tourist  activities,  especially  since  there  will  have  to  be  a  no-­‐go-­‐to-­‐visitors  buffer  zone  on  the  reservoir  edge,  which  will  push  visitor  activities  towards  the  Mandai  Road  and  Mandai  Lake  Road  sides  of  the  site.

  The   suggestion   is   that   this   attraction   will   be   of   a   “lodge”   type,   based   on   rainforest  lodges  in  places  such  as  Costa  Rica  and  Queensland,  so  that  visitors  will  stay  over  to  gain  a  full  nature  experience,  rather  that  use  a  downtown  hotel.  But  with  a  downtown  so  close,  and  when  the  genuine  nature  experience  of  Mandai  will  be  so  limited,  this  seems  unlikely.  The  forest  lacks  big  and  obviously  visible  species  to  be  attractive  to  international  tourists  who  have  the  options  of  bigger  attractions  in  the  neighbouring  countries.  

  In  the  September  27th  Meeting  we  discussed  the  fact  that  perhaps  the  regeneration  of  this   area   towards   being   a   forest,   and   the   existence   of   fruit   trees   from   farming   times,   could  somehow  make   this   into   a   “mini-­‐Eden-­‐Project”   in   the   outdoors,   but   the   interest   of   this   in   a  region  where  the  real  thing  is  so  close  by  will  really  be  negligible.      

  Most  of  the  recent  and  future  expansion  of  tourist  numbers  in  Singapore  is  coming  from  the   region,   from   Indonesia,   Australia,   China,   India   and   Vietnam.   In   2003,   72%   of   visitors   are  from  Asia,  80%  from  Asia  and  Oceania  combined,  while  in  2006,  73%  of  visitors  are  from  Asia  and   81%   from   Asia   and   Oceana   combined.   Tourists   such   as   these   are   not   going   to   want   a  Singapore-­‐style   regenerating-­‐   forest   experience.   They   can   all   find  more   extensive   and   richer  tracts   of   nature   in   their   own   countries,   where   the   nature   experience,   even   with   synthetic  elements,  can  truly  be  “away  from  it  all”.      

  Already,  those  of  us  who  take  tourists  to  the  Tree  Top  Walk,  built  across  a  low  canopy  secondary   forest  area,  have   to  explain  why  one  actually   sees   so   little  animal   life   from   it,  and  why  the  experience  is  more  that  of  being  a  bridge  above  the  canopy,  than  passing  through  the  canopy.
