Response of ponderosa pine forests in central Oregon to prescribed underburning

Creator:

Landsberg, Johanna Dobrot

Abstract:

Tree growth and soil nutrient responses to prescribed underburning were determined for a period of up to 12 years at four sites in northcentral and central Oregon ponderosa pine stands (Pinus ponderosa Dougl. ex Laws). Differences reported are significant at a = 0.10. During the first 4-growing-season-measurement period after underburning,...

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...

Understory competition for resources in Pinus ponderosa forests of northeastern Oregon

Creator:

Riegel, Gregg M.

Abstract:

The objective of this research was to determine which environmental resources, light, water, and nutrients, control understory plant production and composition in a Pinus ponderosa forest in northeastern Oregon. A split-plot experimental design, with three blocks, four treatments, and 44 plots, was established in the summer of 1985. Twenty plots...
