Competitive interactions between Douglas-fir or ponderosa pine and whiteleaf manzanita

Creator:

White, Diane E.

Abstract:

Juvenile Douglas-fir, ponderosa pine, and whiteleaf manzanita growth in southwest Oregon varied with density of co-developing manzanita and presence of herbaceous cover. Plant xylem pressure potential and stomatal conductance of each species was responsive to competition-induced depletion of soil water. Rates varied among species. The best correlations with growth usually...

Effect of western juniper removal on ponderosa pine and associated understory vegetation

Creator:

Rose, Jeffrey A.

Abstract:

This research assessed the effect of western juniper (Junlperus occldentalls) removal on understory plant production and cover and ponderosa pine (Pinus ponderosa) growth and plant water status. A complete randomized block design, with four blocks and four treatments was established in the summer of 1984 near Prineville, Oregon. The four...
