• Landcover data older than 10 years – improved with other data layers.

• Small landuse changes mayhave significant impacts.

High water yield areas that produce ecosystem services , including water, under severe threat from plantations 

and poor landuse management, have to increase protection through various means. These areas also have the last remaining  threatened mountain 

grassland .

• Product as good as the data available, the capacity to analyse and implement – we need to build capacity - to survey, set targets, upgrade SCP, implement.

• Current product: used for soliciting political support for key issues + high level planning and decision support (better than having nothing – direct further work)

• Private Nature Reserves – important but not assessed i.t.o. conservation contribution – audit required to verify status and contribution

• High % of important biodiversity features have no or inadequate protection –prioritise – expand Conservation Estate

• Some PAs contain features found nowhere else in the world – allocate resources• 6 Clusters - 3 important for ecosystem services and biodiversity conservation• Fragmentation in mountain grasslands and forests, and competing landuses

(including forestry) in high water yield to be assessed as a priority• Corridors present a good opportunity for long-term biological movement between

important biodiversity areas but it needs refinement • Cost of ecosystem services to be determined – resource economists needed• Consider potential conflicts between development needs (e.g. mining and

environmental conservation) and develop SUSTAINABLE DEVELOPMENT FRAMEWORK (Green the LEGDP) to ensure provision of ecosystem services

• Development pressure is high ‐ losing opportunities to conserve• Dynamic systems with major pressures  require adaptive management and innovative approaches that are not always based on the best scientific outputs

• Some good data available, work with it while attempting to improve data layersand address gaps

• Conservative approach to  SCP provide for challenges  and constraints   butdo provide basis for getting important messages across (political)  and basic decision support. Also basis to guide future planning 

• Preliminary – conservative SCP can assist if you have major capacity challenges• Conservation Planning  = CYCLICAL PROCESS – P‐LCP to be refined
