Whitebark pine (Pinus albicaulis) growth release potential following overstay disturbance

Abstract

Much of the information available on successional modeling for whitebark pine (Pinus albicaulis) communities is based on research conducted in an ecosystem influenced by maritime conditions (Pacific Northwest). The Greater Yellowstone ecosystem (GYE; Wyoming, Montana, and Idaho, USA) is subjected to more continental climatic conditions and as a result, the dynamics of whitebark pine populations in the GYE may in fact be very different from those of maritime populations. Recent survey work in the GYE shows establishment is common with variable recruitment of young trees in the understory of mature forests. Density and age distribution of these individuals vary greatly among stands across the ecosystem. By determining historical seedling and sapling growth rates and their relation to successional disturbances such as fire, bark beetles (Dendroctonus spp.), and disease, we will be better equipped to guide restoration efforts throughout the GYE and to ensure that management decisions are based on scientific information collected from the ecosystem in which restoration efforts are actually occurring.
