Persistent effects of fire severity on ponderosa pine regeneration niches and seedling growth
Year: 2020
Several recent studies have documented how fire severity affects the density and spatial patterns of tree regenerationin western North American ponderosa pine forests. However, less is known about the effects of fireseverity on fine-scale tree regeneration niche attributes such as understory plant composition and cover, surfacefuel abundance, and soil properties, or how these attributes in turn affect regenerating ponderosa pine growth.Using 1-m2 plots centered on 360 ponderosa pine seedlings that regenerated naturally after the Pumpkin Fire in2000 in Arizona, we quantified regeneration niche…

Response of antelope bitterbrush to repeated prescribed burning in Central Oregon ponderosa pine forests
Year: 2009
Antelope bitterbrush is a dominant shrub in many interior ponderosa pine forests in the western UnitedStates. How it responds to prescribed fire is not well understood, yet is of considerable concern to wildlifeand fire managers alike given its importance as a browse species and as a ladder fuel in these fire-proneforests. We quantified bitterbrush cover, density, and biomass in response to repeated burning in thinnedponderosa pine forests. Low- to moderate-intensity spring burning killed the majority of bitterbrushplants on replicate plots. Moderately rapid recovery of bitterbrush density…
