Development of a Mixed-Shrub-Planted Ponderosa Pine Communicty on a Poor Site After Site Preparation and Release

Relating the survival and growth of planted longleaf pine seedlings to microsite conditions altered by site preparation treatments

“…The dominant fern species throughout the study area was bracken fern (Pteridium aquilinum (L.) Kuhn), which is a common pioneer species in plantations following disturbances such as logging, burning, and site preparation. Herbicides, specifically those that target shrub species, aid establishment of bracken fern by reducing competition for resources (McDonald et al, 1999(McDonald et al, , 2003. Our results suggest that similar site conditions (including an absence of woody competitors) favor both longleaf pine seedlings and bracken fern through 2 years after site preparation.…”

Twenty-six-year response of ponderosa pine and Douglas-fir plantations to woody competitor density in treated stands of madrone and whiteleaf manzanita

“…McDonald et al, 1999;Miller et al, 2003;Rose et al, 2006;Wagner et al, 2006). Growth responses are often quantitatively linked to degree, duration and structure of competing cover, as in McDonald and Abbott (1997).…”
