A Comparison Of Clearcut And Shelterwood Harvesting Effects On Understory Vegetation In Central Virginia Piedmont Forests, Lorelei J. Hartman

Theses & Honors Papers

I compared clearcutting and shelterwood harvesting effects on all understory vegetation (woody and nonwoody) in Piedmont hardwood forests. Clearcutting and shelterwood harvesting are both even.-aged management practices, put in contrast to clearcutting, the shelterwood method retains selected trees as partial canopy. The retained canopy is reported to be beneficial to desired tree species and restrict competition of undesired tree species, grasses and shrubs.·Research comparing the shelterwood method to clearcutting has been limited , particularly in hardwood forests. We collected data on understory plant communities in clearcut, low-leave shelterwood, and mature forest sites (not harvested in

at least 100 years). Percent …

Variability In Water Use By Phreatophytic Banksia Woodland Vegetation Of The Swan Coastal Plain, Western Australia, Sandra Jane Zencich

Theses: Doctorates and Masters

Seasonal changes exist in source-water utilisation by Banksia woodland species overlying a shallow aquifer on the Swan Coastal Plain in Western Australia These were studied to identify the importance of groundwater as a water source to this vegetation. Intra-and interspecific variation in seasonal water use was investigated across the dominant overstorey and understorey species, with particular emphasis on species of different rooting morphologies. Seasonal water use was investigated across a topographical gradient ranging from a groundwater depth of 2.5 to 30 metres, a scenario representative of the coastal sand-dune system. An examination was also made of the response of woodland …
