The expression of functional traits during seedling establishment in two populations of Pinus ponderosa from contrasting climates

Creator:

Kerr, Kelly L.

Abstract:

Vegetation patterns and species distributions are strongly linked to soil moisture regimes, and populations within a species from contrasting climatic regimes could exhibit differences in the degree to which certain functional traits related to establishment are expressed. Tree seedling survival is crucial for forest regeneration, and thus may be a...

Comparative drought tolerance of four Mexican pine species

Creator:

Cuevas-Rangel, Rosalia Adela

Abstract:

Forest tree nurseries in Mexico produce millions of seedlings per year. This is accomplished with high financial investment and unsatisfactory quality control of seedlings. Drought is a major stress factor in Mexico. Thus, planting drought tolerant pine seedlings on dry sites will result in better survival and growth of seedlings....

Tree Vigor Response and Competitive Zone Density in Mature Ponderosa Pine

Creator:

Shaw, Randi C.

Abstract:

This study explored the relationship of mature ponderosa pine (Pinus ponderosa Dougl. ex Laws) tree vigor and competitive zone density following thinning and fuel reduction treatments. Competitive zone density (CZD) was defined as the total tree basal area (m²/ha) surrounding a given ponderosa pine tree within a 10m fixed radius...
