Foraging decisions with conservation consequences: Interaction between beavers and invasive tree species

Abstract Herbivore species can either hinder or accelerate the invasion of woody species through selective utilization. Therefore, an exploration of foraging decisions can contribute to the

Can Understory Plant Composition and Richness Help Designate Riparian Management Zones in Mesic Headwater Forests of the Northeastern United States?

Riparian buffers implemented to minimize sediment, nutrients, and disturbance impacts on streams during forest operations vary greatly in the degree to which ecological criteria are used in

Natural Forest Regeneration Changes in an Urban Natural Area Forest with White-Tailed Deer (Odocoileus virginianus) Exclusion and Felling by North American Beaver (Castor canadensis)

ABSTRACT We examined natural regeneration changes in an urban natural area forest, the Good Woods, Cobbs Creek Park, Philadelphia, Pennsylvania, after placement of exclusion fencing to prevent

Relative Effectiveness of Four Different Guards In Preventing Beaver Cutting of Urban Trees

Beavers are expanding into cities as they recolonize their historic range. While they increase the ecological functioning of urban green areas, human-beaver conflicts occur. Public support to deal



Central Place Foraging by Beavers (Castor canadensis) in a Complex Lake Habitat

Overall, this study shows that central-place foraging theory can predict the behavior of beavers foraging in a complex natural landscape, and the patterns observed have implications for how beavers might influence tree species composition in forests.

Forest disturbance by an ecosystem engineer: beaver in boreal forest landscapes

Natural disturbances are important for forest ecosystem dynamics and maintenance of biodiversity. In the boreal forest, large-scale disturbances such as wildfires and windstorms have been emphasized,

Browse selection by beaver: effects on riparian forest composition

Intense beaver foraging of trembling aspen decreased tree density and basal area by as much as 43% within ~ 1-ha forage zones surrounding two beaver ponds in northern Minnesota, with long-term implications to forest succession and dynamics.

Habitat and forage selection by the American beaver (Castor canadensis) on a regulated river in the Chihuahuan Desert

Examination of habitat and woody forage species during winter along the Rio Grande in southern New Mexico concluded that, while cottonwoods might require protection from beaver foraging, beavers were not having a negative impact on willows and did not promote saltcedars via ecological release.

Revisiting the Role of Aquatic Plants in Beaver Habitat Selection

Assessing whether the availability of woody plants, conditions conducive to theavailability of aquatic vascular plants (macrophytes), and/or other features of basin morphology are associated with the persistence and density of beaver occupancy in 23 lakes over a 50-y period finds that several lakes with abundant Brasenia supported high colony densities and long-term colony occupancy.

An ecosystem engineer, the beaver, increases species richness at the landscape scale

It is suggested that ecosystem engineers will increase species richness at the landscape scale whenever there are species present in a landscape that are restricted to engineered habitats during at least some stages of their life cycle.

Riparian disturbance due to beavers (Castor canadensis) in Alberta's boreal mixedwood forests: Implications for forest management

ABSTRACT Alberta's boreal mixedwood forest has seen intensifying industrial activity in the past several decades, largely from logging and petroleum extraction. At the same time, populations of North

Wetland Vegetation Dynamics in Response to Beaver (Castor canadensis) Activity at Multiple Scales

Abstract: Beaver activity is often considered a hydrologic disturbance that “resets” succession. We determined how beaver impoundment and wetland size and water chemistry affected the vegetation

Central place foraging by beavers (Castor canadensis): a test of foraging predictions and the impact of selective feeding on the growth form of cottonwoods (Populus fremontii)

The selective harvesting of branches predicted by foraging theory affects plant growth form and may influence plant reproductive patterns and the importance of selective branch choice by beavers on patterns of cottonwood reproduction is discussed.
