Identifying Retention Patches – flag/tag or virtual
Description of work:
This work will involve delineating boundaries of retention patches in treatment units. Boundaries will be flagged/tagged for cultural sites only and boundaries will be installed to the standards set forth in the Fremont-Winema National Forest’s Product Accountability Action Plan. All other retention patches will be virtual. See the plan for technical specifications on boundaries.
Objective of the retention patches:
In order to protect special habitats and resource features across the landscape, retention patches would be applied to treatment units. They would be well distributed through the area to provide for wildlife security and habitat, protection of important ecological resources, and diversity of stand structure.
Standards:
1. Each unit will have 15% of the unit area left in retention patches.
2. Shape and size would be varied.
3. Size would range from approximately 0.5 to 5.0 acres, with a median size of approximately 2.5 acres.
4. Retention patches shall not be placed along unit boundaries, except to heavily traveled roads, private property, and openings such as meadows, scab flats, and previous treatments.
Criteria for areas to be retained, in order of priority (cultural sites can be used for retention patches if they meet the following criteria):
1. areas with large diameter trees, high amounts of canopy cover, and decadence components such as broken-topped live trees, mistletoe, cavities, large snags ,and fallen trees
2. patches of denser forest (multi-layered preferred)
3. green trees with damage/cull trees/mistletoe
4. concentrations of snags or woody debris
5. understory Douglas-fir/cedar/pine reproduction, but not dense white fir or lodgepole pine
6. special habitat features, such as rock outcrops and seeps
7. patches of hardwood trees/large shrubs such as serviceberry, willow, plum, cherry, or aspen
8. cool, shaded microhabitats
9. patches of regeneration
10. individual clumps of trees (typically larger ponderosa pine) of varying sizes
11. areas with high plant species diversity
12. areas with dense understory providing big game hiding cover
13. areas with sensitive soils and/or steep slopes
14. areas where road access is limited
