Shade and green houses on the North Slope of Alaska
USGS used shade and green houses to understand the effects of both warmer and cooler temperatures on the growth of plants used by geese for forage. These are located near the Smith River and Point Lonely on the North Slope of Alaska.
Grazing Lawn

Greenhouses and Shadehouses
Typical goose grazing lawns along the Smith River in the Teshekpuk Lake Special Area of the National Petroleum Reserve - Alaska. Greenhouses and Shadehouses are used by USGS biologists to assess the effects of climate change on plant quality and phenology.
