FOREST PATTERN
Managing Stands, Landscapes, and Habitat

Are these forest patterns good or bad wildlife habitat?

Landforms and climate affect forest patterns
Predictable spatial patterns
![Page 4: ESRM 450 Wildlife Ecology and Conservation FOREST PATTERN Managing Stands, Landscapes, and Habitat](https://reader035.vdocuments.us/reader035/viewer/2022062501/568167d4550346895ddd28d4/html5/thumbnails/4.jpg)
Landforms and climate affect forest patterns
Riparian systems have distinctive landform –
vegetation patterns
![Page 5: ESRM 450 Wildlife Ecology and Conservation FOREST PATTERN Managing Stands, Landscapes, and Habitat](https://reader035.vdocuments.us/reader035/viewer/2022062501/568167d4550346895ddd28d4/html5/thumbnails/5.jpg)
Scale measures 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

Habitat loss and fragmentation patterns
![Page 9: ESRM 450 Wildlife Ecology and Conservation FOREST PATTERN Managing Stands, Landscapes, and Habitat](https://reader035.vdocuments.us/reader035/viewer/2022062501/568167d4550346895ddd28d4/html5/thumbnails/9.jpg)
Edge habitat increases rapidly as fragment size decreases

Riparian forests have linear features but with variability in habitat configuration
![Page 11: ESRM 450 Wildlife Ecology and Conservation FOREST PATTERN Managing Stands, Landscapes, and Habitat](https://reader035.vdocuments.us/reader035/viewer/2022062501/568167d4550346895ddd28d4/html5/thumbnails/11.jpg)
Channel configuration affects riparian buffers
![Page 12: ESRM 450 Wildlife Ecology and Conservation FOREST PATTERN Managing Stands, Landscapes, and Habitat](https://reader035.vdocuments.us/reader035/viewer/2022062501/568167d4550346895ddd28d4/html5/thumbnails/12.jpg)
Spatial complexity varies as a function of cutting pattern
What are the implications for habitat?

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?
