Blue Oak Regeneration in Southern Sierra Nevada Foothills1
A survey of blue oak stands in four southern Sierra areas indicated there was a substantial number of seedlings and mature trees, but there were considerably fewer trees in the sapling and pole size class. These differences prompted a long-term survival study. After 6 years, 68.5 percent of the trees were still present and had grown 0.02 inches. A study of aging seedlings showed that the percen...
متن کاملFactors Affecting Blue Oak Sapling Recruitment1
We used logistic regression to identify environmental and management history factors associated with blue oak (Quercus douglasii) sapling recruitment. Recent canopy gaps caused by natural mortality or clearing were positively associated with sapling recruitment. Plots with very high or low levels of tree canopy cover were less likely to have saplings than those with intermediate canopy cover le...
متن کاملOak Shelterwood: A Technique to Improve Oak Regeneration
Oak Regeneration Dynamics Successful regeneration of oak on intermediate and high-quality sites (upland oak site index > 65 to 70 feet) is limited due to the lack of the vigorous advance regeneration and/or saplings/pole-sized trees that are capable of sprouting. Vigorous advance regeneration and/or stump sprouters are required at the time of regeneration on intermediate and highquality sites, ...
متن کاملHotspot detection for chestnut oak regeneration
Chestnut oak regeneration hotspots were investigated in 52 mature mixed-oak stands in the central Appalachians. Four methods: ranking, SaTScan, ClusterSeer, and classification tree were applied to detect chestnut oak regeneration hotspots. Ranking method provided a quick assessment of the regeneration hotspot; SaTScan and ClusterSeer compromised the spatial correlation among the plots; classifi...
متن کاملRegeneration of California Oak Woodlands 2001 - 20051
The first (1981-1984) and second (1991-1994) statewide inventories of California’s oak woodlands found low levels of regeneration for several common oak species. In 2001, a new statewide inventory of California’s oak woodlands was initiated, with 10 percent of field plots measured each year. The first five years of data (2001-2005) were used to examine regeneration and sapling distributions in ...
