This study was conducted to better understand the phenomenon of arctic greening that is being observed. The focus of this study is Northern Alaska, and using the normalized difference vegetation index (NDVI) and satellite imagery to quantify and map greening, it was found that plant composition in  these arctic regions are not changing. Rather, this greening effect is occurring due to a longer growing season, especially in wetter areas of the region where plants respond much faster to the warming temperatures creating this longer growing season.
