The effects of grazing by white‐tailed deer (Odocoileus virginianus) on populations of Trillium spp. were examined in remnant, old‐growth patches of the highly fragmented Big Woods forest ecosystem in southeastern Minnesota. We conducted three separate studies involving an exclosure experiment, transplant experiments, and comparisons of Trillium populations among study sites. The highest grazing intensity was observed where deer occurred at high overwinter concentrations (~25–35/km2… 

Effects of white-tailed deer herbivory on remnant tallgrass prairie plant communities

White-tailed deer (Odocoileus virginianus) abundance is increasing across North America as habitat is created and populations are protected from predation. Their preferred habitat, the forest edge,

Effects of White-tailed Deer (Odocoileus virginianus Zimm.) Herbivory in Restored Forest and Savanna Plant Communities

The results highlight the importance of assessing the species diversity, evenness, and floristic quality of target plant communities to determine the impact of deer herbivory at varying deer densities.

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

Effects of White-Tailed Deer (Odocoileus virginianus) on the Maritime Forest of Bald Head Island, North Carolina

Abstract Overabundance and associated impacts of deer on mainland forests of the United States have been topics of extensive investigation and management discussion. Conversely, deer populations on

Browsing Patterns of White-Tailed Deer Following Increased Timber Harvest and a Decline in Population Density

Overall browsing rates of white-tailed deer declined from approximately 17% in 2001 to less than 5% during this study, suggesting that the combination of deer population control, and increasing the amount of timber harvest across the landscape can reduce herbivory to levels that may not impede growth and survival of forest vegetation.

Effects of white-tailed deer (Odocoileus virginianus) exclusion on plant recovery in overwash fans after a severe coastal storm.

Managing deer to lower abundance may enhance coastal resilience if vegetation is allowed to recover unimpeded by foraging and trampling, though a better understanding of the precise nature of deer impacts on dune vegetation is necessary.



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

Height of White‐Flowered Trillium (Trillium Grandiflorum) as an Index of Deer Browsing Intensity

Based on deer pop- ulation densities associated with study sites supporting Trillium populations with stable stem heights and flowering plants, maintenance of deer densities of 4-6 individuals/km2 is recommended for deciduous forests in northeastern Illinois.

Effects of Leaf Removal on Reproductions vs. Belowground Storage in Trillium Grandiflorum

Although the mean seasonal leaf conductance of partially defoliated plants was greater than that of intact plants, any compensatory increases in photosynthesis that may have occurred were apparently insufficient to prevent the reduced allocation to belowground storage.

The Influence of Feral Goats on Koa Tree Reproduction in Hawaii Volcanoes National Park

A quantitative analysis was made to evaluate the influence of feral goats on tree reproduction of Acacia Koa var, hawaiiensis Rock in the mountain park—land ecosystem on the east flank of Mauna Loa, showing that koa reproduction below 10 cm height is abundant outside the exclosure and at the unfenced colonies, but almost totally missing are suckers.

Escaping Herbivory: Refuge Effects on the Morphology and Shoot Demography of the Clonal Forest Herb Maianthemum canadense

Refugia may allow browse-sensitive plants to persist, albeit at lower densities, in overbrowsed habitats, as reported for other forest herbs throughout the eastern United States from locations where browsing pressure is great.


White-tailed deer have a substantial influence on the reproduction ofHemlock, and on the potential of this species to replace itself in forests where hemlock is the dominant tree species.

Mature Mesophytic Hardwood Forest: Community Transitions, by Layer, from East‐Central Minnesota to Southeastern Michigan

Fragments of old-growth forest in which sugar maple is a principal dominant, i.e., late-successional mesophytic forests, were sampled layer by layer across a floristic gradient from east-central Minnesota to southeastern Michigan, USA to determine whether the community importance of species that are common throughout the study area differs significantly from region to region.

Fire and Other Factors Controlling the Big Woods Vegetation of Minnesota in the Mid‐Nineteenth Century

Reconstruction of the vegetation of the Big Woods and adjacent areas along the prairie-woodland border in south-central Minnesota found that the vegetation was most strongly correlated with the fire-probability pattern, which was a function of both abiotic and biotic factors.
