  1. ESRM 450 Wildlife Ecology and Conservation FOREST PATTERN Managing Stands, Landscapes, and Habitat

  2. Are these forest patterns good or bad wildlife habitat?

  3. Landforms and climate affect forest patterns Predictable spatial patterns

  4. Landforms and climate affect forest patterns Riparian systems have distinctive landform – vegetation patterns

  5. Scalemeasures or quantifies differences among observations Extent(or range) describes the realized scope of a phenomenon or entity of interest Grain(or resolution) describes how finely observations within the extent are divided or distinguished

  6. Grain varies as a function of natural and human-caused factors How does grain affect habitat?

  7. Forest loss Heterogeneity can be vs. retained through awareness fragmentation of landscape features

  8. Habitat loss and fragmentation patterns

  9. Edge habitat increases rapidly as fragment size decreases

  10. Riparian forests have linear features but with variability in habitat configuration

  11. Channel configuration affects riparian buffers

  12. Spatial complexity varies as a function of cutting pattern What are the implications for habitat?

  13. Patch size in the Cascade Range

  14. Riparian buffers determine spatial complexity Willamette NF forest plan

  15. Northwest Forest Plan riparian reserves What are the implications for habitat, fire disturbance?

  16. What kinds of data would you collect to characterize habitat in this landscape? How do you quantify populations of highly mobile organisms in a patchy landscape?
