Day 349: Yesterday, it was my privilege to be part of a revegetation crew working near Sunrise in Mount Rainier National Park. Nowhere on the Mountain is human impact more visible than in the subalpine zone, and particularly here where as late as 1970, a "drive-in" campground was available for visitor use. A gravel road cut through the meadow and hikers were allowed to wander freely through fields of wildflowers, thus creating countless "social trails" where vegetation was trampled and destroyed. The growing season is very short here, and plants did not have time to recover. Eventually, the area was closed to camping and the use of social trails was prohibited, but for the most part, the vegetation did not fill in. Enter revegetation crews, the heroes of the story!


Recurring questions include, "Isn't it kinda late to be planting?" and "What's the survival rate?" First of all, the growing season is very short at this elevation. Snow generally covers the ground from mid to late September until July. These plants have evolved to survive extreme conditions of alpine cold, but new seedlings have one major enemy: lack of water. Summer is a stressful time, even for established plants. Put in the ground in late season, these species stand a far better chance of taking hold. As for the survival rate, it's about 80%, and that's phenomenal.
