This screen may contain a variety of figures or tables of snags and down wood information not included in the cumulative species curves. This information includes wildlife use of height of snag or length of down wood, snag or down wood species, decay class, mortality condition, snag top condition, hollow snag or down wood. Please see the Ancillary Data Methods for details on each figure or table. Some tables and figures may need to be PRINTED IN LANDSCAPE
All Underlying Data for SNAGS
Table WLCH.sp-15. Ancillary data for trees used by wildlife species or groups in Westside Lowland Conifer-Hardwood Forests Wildlife Habitat Type. Snags in reviewed studies were re-classified for this work into one of three decay classes; hard, moderate, or soft, per Bull et al. (1997). "Tree species 1" is the tree species used most often by the wildlife species shown for that particular study. "Tree species 2 is the tree species used next most often, etc. If selection data was available, then Tree species 1 is the tree species most selected by the wildlife species, and so on for Tree species 2, 3, and 4.
| Wildlife Species | Trees sampled (n) | Live trees used (% of all trees used) | Dead trees used (% of all trees used) | Decay class of snag used | Condition of tree top | Hollow tree or snag | Tree species 1 | Tree species 2 | Tree species 3 | Tree species 4 | Wildlife use of tree | Structural Condition Class | Geographic Location | Citation |
