Ponderosa pine (Pinus ponderosa) is a dominant tree species across western North America. Its eastern distribution includes three populations in western Nebraska. This study assesses the distribution, structure and age of ponderosa pine woodlands in one of those regions, the Wildcat Hills. The Wildcat Hills have escaped severe wildfires seen in recent decades in other ponderosa pine regions. Nevertheless, the Wildcat Hills woodlands face multiple threats including climate change, wildfire, drought, pine beetles, and invasive species. Key to these threats is the stand structure of pine woodlands, which have increased in density across much of ponderosa pine’s range. …

Since people have settled along the Boise Front, there have been very few documented fire disturbances. This is likely an outcome of fire suppression policies. There is evidence, visible as scars on living trees, that the old growth ponderosa pines located on the East Side Trail in the Boise National Forest have withstood multiple fires. Samples were collected by using a chainsaw to remove small, partial cross-sections from several trees. The Boise Front master chronology was used to accurately cross-date the fire-scarred samples using COFECHA. Analysis of the samples revealed ten fire events ranging from 1709 to 1889. The fire …
