It is the identification, classification and recording of visual values on maps.

The visible landscape is physically mapped, it is assessed using 35 factors and rated for its visual sensitivity to forest alterations and assigned a Visual Sensitivity Class between 1 and 5.

1. VLI in Review1. VLI in Review• Mapping is completed from public use areas, communities, roads,

water routes, trails etc.

• Identifies what’s visible and not visible.

• Delineates landscape into Visual Sensitivity Units (VSUs).

• Records particulars of each Visual Sensitivity Unit.

Existing Visual Condition (EVC)

Visual Absorption Capability (VAC)

Biophysical Rating (BR)

Viewing Condition (VC)

Viewer Rating (VR)

• Classifies the VSU into one of five Visual Sensitivity Classes (VSC).

4

Existing Visual Condition (EVC):Existing Visual Condition (EVC):

Identifies the existing level of human made alterations on

the landscape at the time the inventory is conducted.

The terminology used is the same as for VQOs except

that it has one more Class (Excessive Modification).

VQO = M vs PR

EVC = M

VQO = M vs R

Visual Absorption Capability (VAC):Visual Absorption Capability (VAC):

Rates the relative capacity of the landscape to absorb

human made alterations and still maintain some visual

integrity. The scale is high, medium, low. The higher the

rating the more ability to absorb alteration.

8

Example of VAC use in design/planningExample of VAC use in design/planningHints as to which harvesting pattern may work & which may not work as easily

9

VAC = Low

Clearcutting will be harder to fit in than thinning or partial cutting

Example of VAC use in design/planningExample of VAC use in design/planningHints as to which harvesting pattern may work & which may not work as easily

10

VAC = High

Clearcutting or small patches are likely to fit in & blend in very well

Biophysical Rating (BR):Biophysical Rating (BR):

Identifies the degree of visual interest in the landscape and

rates the level that it would attract viewer attention. The

scale is high, medium low. The higher the attraction, the

more sensitive it is.

11

Example of BR use in design/planningExample of BR use in design/planningHints as to how spectacular the landscape is

BR = High

Spectacular landscapes will be more challenging to design

Example of BR use in design/planningExample of BR use in design/planningHints as to how spectacular the landscape is

BR = Low

Less spectacular landscapes will be less challenging to design

Viewing Condition (VC):Viewing Condition (VC):Records the conditions under which the landscape is

viewed such as viewing duration and number of viewpoints.

The scale is high, medium & low. The higher the rating the

more you see the landscape and the more sensitive it is.

14

Example of VC use in design/planningExample of VC use in design/planningHints as to how the landscape is viewed

15

VC = High

Highly visible landscapes will be more challenging to design

Example of VC use in design/planningExample of VC use in design/planningHints as to how the landscape is viewed

16

VC = Moderate

Landscapes viewed in less prominent ways will be less challenging to design

Viewer Rating (VR):Viewer Rating (VR):Measures the number of people and their expectations

for visual quality. Ratings are high, medium & low. The

higher the rating the more people view the landscape

and/or are more concerned.

17

Example of VR use in design/planningExample of VR use in design/planningIndicates viewer expectations & numbers of viewers

VR = High

Landscapes with large number of viewers & high expectations will be more challenging to design

Example of VR use in design/planningExample of VR use in design/planning

VR = Low

Landscapes with small number of viewers & lower expectations will be less challenging to design

Indicates viewer expectations & numbers of viewers

Visual Sensitivity Class (VSC) :Visual Sensitivity Class (VSC) :

Rates the sensitivity of the landscape to visual

alteration based on the Biophysical, and Viewing

characteristics described previously.

The rating scale is 1 to 5.

Class 5 has a very low sensitivity to alteration.

Class 1 is very high sensitivity to alteration.

20

Example of VSC 1Example of VSC 1• Meares Island, Tofino. A

spectacular and very attractive landscape.

• Viewed and photographed by hundreds of thousands of people per year from Tofino.

• High biophysical rating, low VAC.

• This is an example of a regional feature and top end VSC-1

21

Example of VSC 2Example of VSC 2

• Mountain along the Tuchodi River

• Another spectacular, attractive mountain.

• Unlike Meares Island this peak is in a remote area where viewer numbers are low.

• VAC is moderate. • The area is used mainly by

ATV riding hunting and fishing.

22

Example of VSC 3Example of VSC 3• Hillside above Shuswap

Lake.

• The VSU has a moderate biophysical rating

• Viewing is from Highway 1 for a short time at an oblique angle.

• Expectations are lower because of existing alterations in the scene and the similarity of the adjacent scenery.

A

23

Example of VSC 4Example of VSC 4

• An uninteresting VSU in the middleground.

• It has a moderate to low biophysical rating and moderate VAC.

• It is viewed infrequently from a secondary road and from a farm.

24

Example of VSC 5Example of VSC 5

• An uninteresting VSU in the mid ground.

• It has a low biophysical rating and medium VAC.

• Infrequent and short term viewing opportunities from a gravel road with low traffic numbers.

In VLI, the VSC is expressed as a rvqc, which is then taken into consideration in the establishement of scenic areas & VQOs.

VLI combined with:

Plan to perspective (P2P) ratios

Visually effective green up (VEG)

Harvesting practices (Clearcutting vs Dispersed retention cutting)

Are used into TSR calculations

Timber availability: Timber available for harvest in the short and near term. Corresponds to the mature merchantable growing stock in the absence of legislative framework (or any other constraint).

Timber supply: estimate of future sustainable timber harvests under a set of rules and for long planning horizons (e.g. 200 yrs).

Traditionally, with a clearcut approach:

% allowed alteration in perspective is converted to % allowed denudation in plan, and the use of VEG

More recently, with a dispersed retention approach:

% basal area removal, or combination of % stems/volume removal with tree height (BCMoF, 1997a)

identifying Potential Scenic Areasidentifying Potential Scenic Areas

VSC may be used as a form of prioritization when determining what areas move forward to becoming scenic areas (e.g. VSC 1-3 may be designated while VSC 4&5 areas may not be proposed for scenic area status).

Under the Forest Planning and Practices Regulation (FPPR) a default VQO is derived by consulting visual sensitivity class contained in VLI, again, based on the Benskin memo as done for rvqcs (For known scenic areas without VQOs only)

Other VLI UsesOther VLI Uses

- To store EVQO & Scenic area status

- Input to Strategic Planning (for the location and significance of scenic areas)

- Input to Operational Plans (as a reference for legal objective, some viewpoints for VIAs, etc.)

- Monitoring & Auditing e.g. Effectiveness & FPB

61

Monitoring & AuditingMonitoring & Auditing

62

C&E: assess performance based on what was approved in the FSP, can lead to fines or other penalties.

FPB: Independent watchdog, investigates based on public complaints or can start its own investigations. Makes public report, recommendations non-binding.

FREP: monitoring program to assess whether FRPA leads to governments’ objectives for each of the 11 values being met.

Effectiveness Evaluations

It is a check form conceived to assess whether an established VQO was achieved in the field.

Process includes 2 assessments:

-Does it meet the word definition?

-Does it meet the numeric calculations considering design, soil disturbance, etc.

Preservation VQO (P): no visible man-made alterations

Retention VQO (R): alterations visually not evident

Partial Retention (PR): alterations visually evident but subordinate

Modification VQO (M): alterations visually dominant but have natural appearing characteristics

Maximum Modification VQO (MM): alterations visually dominant and out of scale

Does it meet the word definitionDoes it meet the word definition

64

% alteration is measured and then adjusted (up or down) based on:

-Roads & soil disturbances

-Within block retention

-Design

-Etc.

So 5% alteration (R) can shift to 7.5% (PR) or to 3% (still R)

Does it meet the “number” definitionDoes it meet the “number” definition
