Deer browse susceptibility limits chestnut restoration success in northern hardwood forests

چکیده

Efforts to develop American chestnuts [Castanea dentata, (Marsh.) Borkh], with improved resistance the chestnut blight fungus, Cryphonectria parasitica (Murr.) Barr, and Phytophthora root rot, caused by Phythophthora cinnamomi Rands, are ongoing. Establishing founder populations of will require understanding ecological silvicultural requirements species. In areas where white tailed deer (Odocoileus virginianus Zimmerman) hinder tree regeneration success, how browsing affect establishment planted is critical. We evaluated impact on survival, growth competitive status hybrid in 15 northern hardwood sites Pennsylvania. found that after six years, fences were 65 percent taller 35 larger basal diameter than unfenced areas. Browsing shifted dynamics faced favoring slower growing, browse tolerant species reducing heights competing woody stems. Nevertheless, plots remained stagnant over time due repeated browsing, while it increased fenced time. Our results suggest fencing or other means herbivory be necessary protect moderate high densities.

Sustainability of the Selection System in Northern Hardwood Forests

The selection silvicultural system is widely recommended for sustainable management of North American cool-temperate tolerant hardwood forests, yet concerns about high-grading, excessive removals, and adequate regeneration persist. We used field measurement of 96 recently harvested stands in the Great Lakes Region of the United States, under corporate, nonindustrial private, and state ownership...

Ecological restoration success is higher for natural regeneration than for active restoration in tropical forests

Is active restoration the best approach to achieve ecological restoration success (the return to a reference condition, that is, old-growth forest) when compared to natural regeneration in tropical forests? Our meta-analysis of 133 studies demonstrated that natural regeneration surpasses active restoration in achieving tropical forest restoration success for all three biodiversity groups (plant...

Fine root respiration in northern hardwood forests in relation to temperature and nitrogen availability.

We examined fine-root (< 2.0 mm diameter) respiration throughout one growing season in four northern hardwood stands dominated by sugar maple (Acer saccharum Marsh.), located along soil temperature and nitrogen (N) availability gradients. In each stand, we fertilized three 50 x 50 m plots with 30 kg NO(3) (-)-N ha(-1) year(-1) and an additional three plots received no N and served as controls. ...

Assessing Ecosystem Restoration Alternatives in Eastern Deciduous Hardwood Forests Using Avian Nest Survival

The effects of anthropogenic forest disturbance on avian populations are only starting to be understood, with most research focusing on community richness and species abundance. Monitoring nesting survival is becoming an important and increasingly reliable method for assessing habitat quality. We investigated nest survival and Brown-headed Cowbird nest parasitism of 18 Neotropical migratory bir...
