ESRM 450 Wildlife Ecology and Conservation FOREST PATTERN Managing Stands, Landscapes, and Habitat
Landforms and climate affect forest patterns Predictable spatial patterns
Landforms and climate affect forest patterns Riparian systems have distinctive landform – vegetation patterns
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
Grain varies as a function of natural and human-caused factors How does grain affect habitat?
Forest loss Heterogeneity can be vs. retained through awareness fragmentation of landscape features
Edge habitat increases rapidly as fragment size decreases
Riparian forests have linear features but with variability in habitat configuration
Spatial complexity varies as a function of cutting pattern What are the implications for habitat?
Riparian buffers determine spatial complexity Willamette NF forest plan
Northwest Forest Plan riparian reserves What are the implications for habitat, fire disturbance?
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?
