5. What is an REA? Broadly speaking, REAs try to… Identify and map species and habitats in the environment and describe how they are changing over time, and what may be causing that change Identify and map species and habitats in the environment and describe how they are changing over time, and what may be causing that change Collect, compile, and synthesize data in a 18- 24 month window to provide a regional snap shot of conditions. They are rapid! Collect, compile, and synthesize data in a 18- 24 month window to provide a regional snap shot of conditions. They are rapid! Focus on large areas and look at the really big picture instead of a particular lake or river Focus on large areas and look at the really big picture instead of a particular lake or river Find data gaps critical to our understanding of the region.

6. Land Status

7. Assessment Components 20 Regionally Important Management Questions Aquatic and Terrestrial Species and Habitats Fire, Invasive Species, Permafrost, Development

8. Nine Terrestrial Habitats Tidal marsh Coastal plain moist tundra Coastal plain wetland Sand sheet wetland Sand sheet moist tundra Foothills tussock tundra Alpine dwarf shrub Tidal marsh Marine beach, barrier islands, and spits

10. Three Aquatic Habitats and Five Fish Species Deep connected lakes Shallow connected lakes Large and small streams Dolly Varden Broad whitefish Burbot Chum salmon Arctic grayling

11. Invasive Species Development Change Agents Permafrost Fire

12. January Temperature – Long-term Warming Winter warming will be greatest in the east, with a shift of about 8°F by the 2060s.

13. September Precipitation – Reduced Snowfall Precipitation more likely to fall as rain than snow

14. Invasive Species Currently highly resistant Increased possibility of invasion by cold- tolerant non-native species

15. Human Footprint Future human footprint estimates from North Slope Science Initiative's (NSSI) scenarios project Overall landscape condition very high Significant data gap

16. Cumulative Change Change Agents: January Temp July Temp Annual precipitation Permafrost Active Layer Relative flammability Human footprint Invasive species vulnerability

17. Warming Impacting Arctic Foxes Change in mean annual temperature from 2010- 2060 within modeled distribution of Arctic fox. Warmer temperatures = less snow in late winter Less prey Increase competition with red fox

18. Increased Shrub Cover Increased air temperature and precipitation likely to increase shrub cover Increased shrubs may increase food availability for herbivores like moose Increased shrub cover may increase likelihood of fire

21. Caribou Length of the growing season will increase by about 2 weeks May increased nutrient value of forage with peak lactation increasing calf survival May result in calves born after most of food has emerged, reducing calf survival
