Regeneration Patterns In Silvicultural Openings Of Western Great Lakes Northern Hardwood Forests 15-24 Years Post-Harvest, Matthew S. Vandermolen
Regeneration Patterns In Silvicultural Openings Of Western Great Lakes Northern Hardwood Forests 15-24 Years Post-Harvest, Matthew S. Vandermolen
Dissertations, Master's Theses and Master's Reports
In managed northern hardwood forests, successful forest regeneration can depend on the application of silvicultural methods tailored to stand-specific recruitment limitations. The objective of this research is to develop a deeper understanding of the factors that interfere with tree regeneration at three long-term, well-replicated experimental canopy gap studies in the upper Great Lakes region, USA. Chapter 2 examines regeneration at a hemlock canopy gap study 18 years post-harvest that included deer exclosures and a gradient of gap sizes. Chapter 3 investigates the spatial patterns of low-density regeneration along gradients of gap size and different levels of legacy-tree retention at two …
The Effects Of Early Pruning On The Near-Ground Branch Density Of Four Live Fencing Species, Aric Devens
The Effects Of Early Pruning On The Near-Ground Branch Density Of Four Live Fencing Species, Aric Devens
Dissertations, Master's Theses and Master's Reports
Crop losses in home gardens greatly impact the wellbeing of rural West African families. Herbivory by migratory or local livestock represents a significant source of crop loss. Live-fencing gardens with thorny hedges is a low-cost and sustainable strategy for reducing losses due to herbivory. However, guidance on the establishment of thorny hedges is inconsistent, poorly publicized, and often anecdotal. Therefore, this study evaluated the effects of three early pruning treatments on near-ground branch density of four thorny species: Vachellia nilotica, Senegalia laeta, Senegalia mellifera, and Prosopis juliflora. Physical measurements and photographic data indicated that after one growing season, V. …
