Description:
Abstract: Some of the SNK rasters intentionally do not align or have the same extent. These rasters were not snapped to a common raster per the authors' discretion. Please review selected rasters prior to use. These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - A raster dataset of relative condition of the landscape, pristine to degraded, based on the intensity and distribution of development in the in the Seward Peninsula – Nulato Hills – Kotzebue Lowlands (SNK) Rapid Ecoregiional Assessment (REA). . Anthropogenic stressors come in many forms, from regional patterns of acid deposition or climate-induced ecosystem change, to local-scale patterns in agricultural drainage ditches and tiles, point-source pollution, land-conversion, and transportation corridors, among others. To be effective, a landscape condition model needs to incorporate multiple stressors, their varying individual intensities, the combined and cumulative effect of those stressors, and if possible, some measure of distance away from each stressor where negative effects remain likely. Since our knowledge of natural ecosystems is varied and often limited, a primary challenge is to identify those stressors that likely have the most degrading effects on ecosystems or species of interest. A second challenge is to acquire mapped information that realistically portrays those stressors. In addition, there are tradeoffs in costs, complexity, the often varying spatial resolutions in available maps, and the variable ways stressors operate across diverse land and waterscapes. Typically, expert knowledge forms the basis of stressor selection, and relative weighting. Once models are developed, they may be calibrated with field measurements. Developing empirical relationships between stress variables and ecological response variables is a key to providing insights into how human activities impact ecological condition (Danz et al. 2007).
Purpose: There are two primary uses for NatureServe’s landscape condition model: 1) to map the predicted ecological conditions one would encounter in the field, based on apparent stressors present across the landscape of interest, and 2) facilitate repeated predictions of ecological condition within the same landscape over time, or given alternative land use proposals. Maps predicting relative ecological condition can provide a screening tool for gauging anthropogenic stress in locations including any mapped point or polygon. Repeated predictions of ecological condition assist with evaluating likely effects of changes in overlapping land uses on the condition of the landscape for an element or group of elements. This can provide a powerful tool understanding cumulative effects of land use change over time and/or for modeling environmental restoration options. The landscape condition model is integrated into NatureServe’s Vista software (NatureServe 2009).

Process Step:
Process Description: The model was run using eight current development footprint datasets: current community, current road, current trail, abandoned railroad, current landing strip/airport, open contaminated site, active/historic mine, and active military lands. Condition weightings for intensity and distance decay were identified for each development class and used to model the landscape condition (see SNK Final Report).
