Effects of Seedling Protectors and Weed Control on Blue Oak Growth and Survival1
Two factors limiting successful recruitment of planted blue oak (Quercus douglasii) seedlings are dry soils and animal damage. Many approaches have been used to mitigate these factors including several types of protective cages and alternative methods of weed control. This study examined how treeshelters, screen cages and varying intensities of weed removal affect the establishment and growth o...
متن کاملGrowth of Blue Oak on California's Hardwood Rangelands1
An individual tree basal area increment model was developed for blue oak (Quercus douglasii Hook. & Arn.) in California, an important woodland tree for wildlife habitat. Box-Cox regression based on 895 increment cores that showed current basal area and the relative size of the tree crown were significant variables. Models to link basal area changes over time with tree height and crown cover wer...
متن کاملLong-term Growth and Persistence of Blue Oak (quercus Douglasii) Seedlings in a California Oak Savanna
We report on growth and survivorship of two cohorts of blue oaks Quercus douglasii Hook. & Arn. (Fagaceae) monitored at Hastings Reservation in Monterey County, California, the first growing in an unprotected old field and measured as seedlings in 1965 and the second planted as acorns in 1985 in several sites differing in their degree of protection from grazing. Growth of all individuals was ex...
متن کاملEffects of Wild Pigs on Seedling Survival in California Oak Woodlands
Wild pigs were established around coastal Spanish settlements in California in the 1800s and expanded over the last century by hunting introductions, domestic releases, and natural dispersal. The current distribution of wild pigs is closely associated with oak woodlands where foraging and rooting by the species may impinge on many native species. Rooting disturbance by wild pigs may be especial...
متن کاملInfluence of Physical, Chemical, and Biological Mine Soil Properties on White Oak Seedling Growth
Landowners in the Appalachian region are becoming increasingly interested in restoring the native hardwood forest on mined land after reclamation. Trees are usually planted in topsoil substitutes consisting of blasted rock strata from the geologic profile. Reforestation attempts using native hardwoods have often been unsuccessful due to the highly variable nature of the physical, chemical, and ...
