We collected information on the geomorphic, topographic, hydrologic, pedologic, and vegetation characteristics of ecosystems within a network of 294 field plots, of which 90 were sampled by us in 2014, and 204 were sampled by the Alaska Natural Heritage Program (AKNHP) and NPS in 2009–2010. The plot network encompassed all of the major environmental gradients and landscape histories present in ANIA. Individual state-factors (e.g., soil pH, slope-aspect) and other ecosystem components (e.g., geomorphic unit, vegetation species-cover data) were measured or categorized using standard classification schemes developed for Alaska. We described and analyzed the hierarchical relationships among the ecosystem components to classify 48 ecotypes (local-scale ecosystems) that best partition the variation in soils, vegetation, and disturbance properties observed at field plots. From the 48 ecotypes, we developed classifications of soil landscapes and disturbance landscapes that could be mapped across the park.
