Competitive interactions of whiteleaf manzanita, herbs, Douglas-fir, and ponderosa pine in southwest February Canadian Journal of Forest Research Diane E.

White. Small stands of Sierra Nevada conifers, primarily Pinus ponderosa and P. jeffreyi, occur up to 60 km east of the eastern limits of the Sierra Nevada montane forest. These stands range from one to several hectares, are largely devoid of characteristic Great Basin species, and are restricted to outcrops of azonal soil derived from hydrothermally Cited by: Using an experimental, long-term density and shrub removal study of ponderosa pine (Pinus ponderosa Lawson & C.

Lawson) on a poor-quality site with low water-holding capacity and high runoff of the North Coastal mountain range in California, we examined the relationships between radial growth and climate for these trees over a common interval Author: Kaelyn Finley, Jianwei Zhang.

Site preparation is used to favor seedling regeneration and establishment by enhancing growing conditions and increasing resource availability, yet few studies have compared different site preparation techniques on growth and yield of trees over multiple decades.

We destructively sampled year old trees of western white pine (Pinus monticola Douglas ex D. Don) and Interior Douglas-fir. Abstract. Dusky-footed woodrats (Neotoma fuscipes) are important components of forest communities, including serving as a primary prey of the California spotted owl (Strix occidentalis occidentalis), a species of concern in examined habitat associations of the dusky-footed woodrat at 4 study sites in mixed-conifer forest of the northern Sierra Cited by: Dusky-footed woodrats (Neotoma fuscipes) are important components of forest communities, including serving as a primary prey of the California spotted owl (Strix occidentalis occidentalis), a species of concern in California.

Plant competition for resources is a major component of plant interference. Field experiments were conducted in the summers of and to study competition at two soil fertility levels. Mixtures and pure stands of beans (Phaseolus vulgaris L.) and beets (Beta vulgaris L.) were established, involving nine population density combinations and three pure stand densities per.

Longleaf pine bud development: influence of seedling nutrition. Treesearch. Barnett; D. Jackson; R. Dumroese. A subset of seedlings from a larger study (Jackson and others) were selected and evaluated for two growing seasons to relate bud development, and root-collar diameter (RCD), and height growth with three nursery.

Lifting Pine Seedlings. Treesearch. Briscoe. One of the factors preventing more widespread planting of the true pines (Pinus spp.) in the tropics is the present necessity of using potted stock instead of barerooted seedlings, such as are used throughout the temperate seedlings require more space, more equipment, more labor, and more money.

Savannas, Barrens, and Rock Outcrop Plant Communities of North America Savannas and barrens were major components of the historic North American landscape before it was extensively altered by agricultural and urban development during the past century.

Western white pine (Pinus monticola), ponderosa pine (P. ponderosa), sugar pine (P. lambertiana), and white fir (Abies concolor) are included with other species in mountain portions of the western part of the region.

In the east, Fraser fir (Abies fraseri), balsam fir (A. balsamea), and red spruce (Picea rubens) are found in the superhumid region.

The low concentration of water vapor in the air, compared with that inside the leaves, is the major driving force for water loss from leaves which, in turn, drives water transport along the gradient in hydrostatic pressure between the xylem in roots and leaves, and down a gradient in water potential between the soil and the cells in the roots Cited by: Book Review Nitrogen Fixation in Tropical Cropping Systems Ken E Giller CAB I Publish ing.
