Shelterwood-Planted Northern Red Oaks: Integrated Costs and Options
Rather than evaluate only planting costs, we estimate the cost of producing a successful seedling (i.e., one that is likely to attain a dominant or codominant crown position by stand age 11). This provides a more realistic cost estimate, since the objective is to obtain a given number of competitively successful trees. Thus, the cost of trees that are likely to die or not attain a competitively...
متن کاملRelationship Between Resistance to Phytophthora ramorum and Constitutive Phenolic Chemistry in Coast Live Oaks and Northern Red Oaks
Phytophthora ramorum causes lethal canker diseases and extensive mortality in coast live oak (CLO) (Quercus agrifolia) and tanoak (Lithocarpus densiflorus). No practical controls are available for this disease in non-urban environments. Therefore, characterization of natural resistance is highly desirable. Variation in resistance to P. ramorum has been observed in CLO in both naturally infected...
متن کاملEffects of Visual Grading on Northern Red Oak (Quercus rubra L.) Seedlings Planted in Two Shelterwood Stands on the Cumberland Plateau of Tennessee, USA
Artificial regeneration of oak has been generally unsuccessful in maintaining the oak component in productive upland forests of eastern North America. We tested visual grading effects on quality-grown northern red oak (Quercus rubra) seedlings planted in two submesic stands on the Cumberland Plateau escarpment of Tennessee, USA. Seedlings were grown for one year using advanced fertilization and...
متن کاملCompetitive Capacity of Quercus rubra L. Planted in Arkansas' Boston Mountains
Results of an 11 yr study of the growth and survival of planted northern red oak (Quercus rubra L.) seedlings (2-0 bare-root) are presented. More than 4,000 seedlings were planted under shelterwood overstories that were harvested 3 yr after planting. Results are expressed as planted-tree dominance probabilities. Dominance probability is the probability that a planted tree will live to attain a ...
متن کاملWater relations and growth of loblolly pine seedlings planted under a shelterwood and in a clear-cut.
We investigated the influence of shelterwood conditions on water relations and growth of loblolly pine (Pinus taeda L.) seedlings on two harsh sites in eastern Texas. Site I was harvested to provide four overstory density treatments (0, 2.3, 4.6 and 9.2 m(2) of residual basal area per ha). To quantify the effects of overstory competition, trenched and nontrenched subplots, each containing 25 on...
