  1. Putting it all together Analysis Define Task Automate Find Data Document • Prep Data • Download • Un-compress • Define Projections • Convert File Formats • Project to desired SRS Disseminate Cartography Web Publishing Ok? Load in ArcMap Paper

  2. Habitat Suitability Indexes • How suitable is a habitat for a given species? • Index: • 0: Habitat inhospitable • 1: Habitat perfect • Computed from rasters representing “environmental conditions” • Elevation, climate, land cover • Distance to water, etc.

  3. Example Layers • Global: • Climate: WorldClim • Remotely Sensed: MODIS, LantSat • Elevation: GTOPO, ETOPO • Continental US: • Climate: PRISM, DayMet: • Elevation: National Elevation Dataset • Water: National Hydrology Dataset • Local: • ?

  5. Potential Habitat Models • Tamarix spp. (Tamarisk, Salt Cedar) • Modeled from Temperature and Precipitation

  6. Geographical Space Observed Occurrences Realized Niche/Distribution Environmental Space Fundamental Niche/Distribution Model Fitted to Occurrences Adapted from Richard Pearson, Center for Biodiversity and Conservation at the American Museum of Natural History

  8. Habitat Suitability Models

  9. Pikas • High Elevation • Specific Temps • Specific Land Cover Types

  10. Pika Habitat Suitability • Land cover: • Rock: 0.9 • Snow and ice: 0.7 • Herbaceous veg: 0.5 • Evergreen: 0.1 Monthly Minimum Temperature Elevation 1 1 Suitability Suitability 0 0 0 5 2500 3600 Degrees C Meters
