- Context! Start with the big picture and drill down to more efficiently know where to put effort (priority places) for projects to better a ecological system or at least minimize harm to an ecological system.
- Rapid – no research – data or models Ecoregions - identify through the analysis of the patterns and the composition of biotic and abiotic characteristics that affect or reflect differences in ecosystems – geology, veg, geomorphology, climate, soils, land use, wildlife, hydrology. In NGB Snake R. Plain, Northern Basin and Range Assessment of future conditions – what risks, what might affect change in processes and ecosystems
- Ecol Functions – ecosystems services – support surrounding environment, e.g floodplain – flood control, sediment deposition, riparian veg; use of veg type to characterize habitat distributions; Pygmy Rabbit Priority Habitat characterized by soil characteristics (depth and percent clay), sagebrush, elevation, and fire frequency Potential to change – based on future impacts – climate change, development Resilience (stability and tolerance) : meaning how an ecosystem can resist damage and quickly recover from disturbances (fire, flooding, fracking, deforestation). Can use info to drive mgmt. practices – alter human behavior or development to result in less adverse impacts.

- Ecological status is determined in part by the impacts of various change agents on the CEs By and large this presentation won’t get much into our methods. There are hundreds of pages of appendices and metadata files that explain what we did to arrive at the final datasets and conclusions if you want to more. For much of the status assessments the basic steps involved building conceptual models that explain our assumptions about the nature of the relationship between conservation elements and change agents. These relationships plus the spatial data that we acquired and developed, led to the creation of process models that documented the ‘mechanics’ of the analytical process. Process models were then expressed as working spatial models that used the input data to create the analytical results as both maps and tables. We relied heavily on ArcGIS models and python scripts to do much of the spatial data but we also used specific tools like Maxent and Circuitscape.
