- SFI Visual Objective
- Visual Preference Research
- Applications
3The Concern
- Forestry
operations are highly visible and are subject to
the perceptions and opinions of an
environmentally aware public. - These operations may have a dramatic visual
impact on the forest landscape. The image of the
forest management is directly influenced by the
scenic quality of forest operations. - Conducting these operations in an
aesthetically acceptable manner is important to
the future of the forest management. - Concerns about the aesthetics of forest
operations can be addressed by using forest
aesthetic guidelines and principles. -

5- Visual Preference
-
- What people like
- What they do not like
- Why?
- What we can do to minimize negative effects
6Focus Group Findings
- Public reaction to forestry operations
- Tree retention
- Green-up
- Slash
- Buffers
- Signage
87 of our perception of the landscape is visual
7 Tree Retention
8 Green-up
9Slash
10Buffers
11The concept of using buffers in land use planning
and design is a mechanism for separating
incompatible land uses . Buffers as a practice in
forestry should be viewed similarly.

aesthetics - and visual preference?

19SFI Objectives
- Utilize best scientific information
- Ensure long term forest productivity
- Protect water quality
- Manage for wildlife habitat and biological
diversity - Manage the visual impact of forest operations
- Manage for ecological, geologic, cultural and
historic qualities - Promote the efficient use of forest products
- Cooperate with wood procurement and landowner
assistance programs - Report to SFI Program on progress
- 10.Provide opportunities for the public to
participate in sustainable forestry - 11.Promote the continual improvement of practices
through monitoring
20SFI Visual Objective
- Manage the visual impact of harvesting and other
forest operations - Performance measures
- Program participants will have policies to manage
the impact - of harvesting on visual quality.
- Program participant shall adopt appropriate
policies for managing - the size, shape, and placement of clearcut
harvests. - Program participants will adopt a green-up
requirement or other, - more comprehensive methods that provide age,
habitat, and aesthetic - diversity
- Program participants shall use harvest methods,
age classes and judicious placement - of harvest units to promote diversity across the
landscape. -

What do people like and what dont they like.and
how do we know?

60Terms
- Understanding Making sense of what is going on.
Partially dependent on prior experience.
Preferences are likely greater when understanding
is facilitated. -
- Exploration To find out more about what is
going on in ones surroundings. Partially
dependent on prior experience. Preferences are
greater where exploration is facilitated. -
- Inference Degree of inference required in
extracting information from a scene.
61Terms
- Coherence Sense of order, how the scene hangs
together. - Complexity Number of different visual elements.
- Legibility - How easy it is to understand and
remember. - Mystery How one is drawn into the scene....bend
in the road, opening in the forest.
