Alpine treelines are very unique ecotones which are visibly responding to climate change worldwide. As global climate change persists alpine treelines are expected to migrate into higher elevations. Not all alpine treelines however are uniform and the microclimates created at the surface have seen to be essential for seedling establishment. The particular microclimate along treeline will dictate how heat is distributed which will ultimately control tree survival. This study discusses how wind interacts with treelines when coming from different directions and where areas of sheltering are created. An area of interest was created along treeline on Pikes Peak in Colorado where wind speeds were measured along a transect moving from the forest up to the tundra above. As expected it was found that a large sheltered area of slow air was created when wind moves uphill over the forest. Downhill moving wind shrinks this sheltered area especially during periods of faster wind. Wind parallel to treeline was found to be more turbulent and sensitive to the local spatial structure. As climate change intensifies it is expected that these sheltered zones created by treeline structure will be altered and become more essential for seedling establishment.
