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 month window to provide a regional snap shot of conditions. They are rapid! Collect, compile, and synthesize data in a month window to provide a regional snap shot of conditions. They are rapid!

Invasive Species Development Change Agents Permafrost Fire
January Temperature – Long-term Warming Winter warming will be greatest in the east, with a shift of about 8°F by the 2060s.
September Precipitation – Reduced Snowfall Precipitation more likely to fall as rain than snow
Invasive Species Currently highly resistant Increased possibility of invasion by cold- tolerant non-native species
Human Footprint Future human footprint estimates from North Slope Science Initiative's (NSSI) scenarios project Overall landscape condition very high Significant data gap
Cumulative Change Change Agents: January Temp July Temp Annual precipitation Permafrost Active Layer Relative flammability Human footprint Invasive species vulnerability
Warming Impacting Arctic Foxes Change in mean annual temperature from within modeled distribution of Arctic fox. Warmer temperatures = less snow in late winter Less prey Increase competition with red fox
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

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
