Application of Risk Models in Shrubland Management
Authored By: M. M. Rowland, L. H. Suring, M. J. Wisdom
Federal agencies need information about habitat requirements and conditions for species and groups of species at spatial extents that are typically used in land management planning. To demonstrate the application of our threats modeling results (Species’ Habitats at Risk) to land management in the Great Basin, we used species groups (Selecting and Grouping Species of Concern) to generalize the spatial patterns of habitat at risk at the watershed scale in the Great Basin.
Subsections found in Application of Risk Models in Shrubland Management
- Characterizing Habitat Conditions : We used two habitat variables, habitat abundance and habitat at risk of displacement by cheatgrass, to characterize the composite habitat conditions for each species group at the watershed extent within the Great Basin.
- Prioritizing Restoration Activities : Different combinations of habitat abundance and habitat risk have different implications for conservation and restoration.
- Integration of Multiple Stressors : The combined risk of displacement by cheatgrass and by pinyon-juniper woodlands was evaluated for the 4.8 million ha of sagebrush in the three ecological provinces in which the pinyon-juniper model was applied.
- Management Implications : Our analyses revealed that watersheds vary in spatial patterns of habitat abundance and risk, resulting in different implications for conservation and restoration of habitats.
