Abstract Changes in habitat and reduction in predation and hunting pressure are two primary causes of high-density populations of white-tailed deer (Odocoileus virginianus) in many areas of eastern North America. Despite increasing recognition of the major effects deer exert on forest communities, deciding when deer are overabundant remains a major challenge to managers charged with conserving native plant communities. In this context, we define overabundance as a condition where deer are… 
Deer and Understory Plant Responses to a Large-Scale Herd Reduction on a Georgia State Park
Although the viability of lethal removal of deer from a park was demonstrated and post-reduction benefits were measured, increased reproduction by the residual deer population highlighted the need for continued deer management, including subsequent removals.
Vegetative Legacy of a Protected Deer Herd in Cades Cove, Great Smoky Mountains National Park
Abstract Overabundant deer populations pose significant challenges to the conservation of native plant communities. We examined the effects of a protected white-tailed deer (Odocoileus virginianus
Tribal and state ecosystem management regimes influence forest regeneration
Deer Facilitate Invasive Plant Success in a Pennsylvania Forest Understory
It is concluded that deer overabundance facilitates the success of invasive species in forested ecosystems and that management will benefit by considering these factors jointly.

Regardless of the population control adopted, success at maintaining forest ecosystems require regulating deer below biological carrying capacity, as measured by ecological impacts, not solely by cultural acceptance.
Deer and invasive plants in suburban forests: assessing variation in deer pressure and herbivory
ABSTRACT Fragmented suburban forests of the northeastern US are challenged by abundant white-tailed deer and nonindigenous plant invasions. Deer browsing/grazing pressure varies among sites,
Woody regeneration response to over a decade of deer population reductions in Indiana state parks1
The results indicate that the void in forest understories created by chronic herbivory in Indiana state parks is being filled by a diverse array of species following deer population reductions.


Predictors of white-tailed deer grazing intensity in fragmented deciduous forests
Results show that parks and preserves with low densities of palatable plant species in the forest understory may be especially susceptible to effects of deer grazing, and changes in landscape composition should be an important consideration in the management of deer densities in areas designed to protect native forest communities.
Effects of white-tailed deer on populations of an understory forb in fragmented deciduous forests.
It is suggested that changes in landscape structure and local deer abundance have altered plant-deer relationships such that grazing can lead to the local extirpation of sensitive forbs such as Trillium spp.
Forests Too Deer: Edge Effects in Northern Wisconsin
Abstract: Browsing by white-tailed deer (Odocoileus virginianus) can profoundly affect the abundance and population structure of several woody and herbaceous plant species. Enclosure studies and
Managing the Abundance and Diversity of Breeding Bird Populations through Manipulation of Deer Populations
Populations of deer in protected areas are capable of causing significant shifts in the composition and abundance of bird communities that can be reversed by increasing the density and diversity of understory vegetation, which can be brought about by reducing deer density.
Contrasting the summer ecology of white-tailed deer inhabiting a forested and an agricultural landscape
It is suggested that rural deer adapted to the rarity of natural forage by exploiting agricultural crops by exploiting Agricultural crops.
Effects of White-tailed Deer (Odocoileus virginianus) on Plants, Plant Populations and Communities: A Review
Whereas deer density is clearly important in determining spatial and temporal variation in the presence and magnitude of deer effects, other factors that may modify the effects of deer density are poorly understood.
Effect of white-tailed deer on songbirds within managed forests in Pennsylvania
White-tailed deer populations have been maintained at high densities in Pennsylvania for several decades with unknown effects on songbirds and their habitats, but species richness of intermediate canopy-nesting songbirds declined and abundance declined between lowest and highest deer densities.
Social organization in deer: Implications for localized management
Populations of white-tailed deer (Odocoileus virginianus) inhabiting many state and national parks and suburban areas have grown to the point that they conflict with human activities. Conflicts range
