Recreation changes the use of a wild landscape by corvids

  title={Recreation changes the use of a wild landscape by corvids},
  author={Lauren E Walker and John M. Marzluff},
ABSTRACT As urban areas have grown in population, use of nearby natural areas for outdoor recreation has also increased, potentially influencing bird distribution in landscapes managed for conservation. Members of the family Corvidae (crows, ravens, jays, and magpies) have strong interactions with humans and may be directly affected by recreation in wild landscapes. In Mount Rainier National Park, we evaluated the effects of vegetation, visitor use, and the availability of human-subsidized food… Expand
When protected areas produce source populations of overabundant species
Abstract While protected areas are a cornerstone of biodiversity conservation, human activities in these areas can negatively affect native species in direct and indirect ways. However, the potentialExpand
Simulating the success of trail closure strategies on reducing human disturbance to nesting Golden Eagles
ABSTRACT As nature-based recreation grows in popularity, there is concern for reduced fitness of animals exposed to chronic disturbance by these activities. Golden Eagles (Aquila chrysaetos) andExpand
Potentially negative ecological consequences of animal redistribution on beaches during COVID-19 lockdown
Abstract Significant changes in the intensity or distribution of human activities, like during the 2020 COVID-19 lockdowns, can cause rapid changes to the diversity, distribution and abundance ofExpand
Steller's Jay (Cyanocitta stelleri) space use and behavior in campground and non-campground sites in coastal redwood forests
ABSTRACT Small-scale disturbance and trash associated with campgrounds may provide opportunities for generalist species in areas important for conservation. We examined the influence of campgroundsExpand
Influence of food subsidies on the foraging ecology of a synanthropic species in protected areas
The impacts of seemingly spatially constrained human recreational activities can have spillover effects on animal communities at relatively broad spatial scales within protected areas. Expand
Minimal bias in surveys of grassland birds from roadsides
ABSTRACT Edges, including roads, can have unintended deleterious impacts on wildlife. However, roads also present opportunities for replicable, and spatially and temporally consistent, wildlifeExpand
Reducing anthropogenic subsidies can curb density of overabundant predators in protected areas
Abstract Protected areas safeguard biodiversity and provide opportunities for human recreation. However, abundant anthropogenic food subsidies associated with human activities in protected areas canExpand
Lifetime reproductive success of Snowy Plovers in coastal northern California
Results indicated that enhancing the cryptic nature of substrates (for eggs and chicks) may be a productive means of increasing reproductive success in this threatened species. Expand
Behavioral mechanisms leading to improved fitness in a subsidized predator
Jays appeared to be under-matched to prevalent resource subsidies despite high densities and behaviors expected to lead to resource matching, and results indicate that local resource subsidies within protected areas can result in source habitats for synanthropes, potentially impacting sensitive species over broader spatial scales.

Where the Wild Things Are: A Research Agenda for Studying the Wildlife-Wilderness Relationship
We explore the connection between US designated Wilderness areas and wildlife with the goal of establishing a research agenda for better understanding this complex relationship. Our research agendaExpand


Corvid response to human settlements and campgrounds : Causes, consequences, and challenges for conservation
Abstract Human development often favors species adapted to human conditions with subsequent negative effects on sensitive species. This is occurring throughout the urbanizing world as increases byExpand
Relative importance of habitat quantity, structure, and spatial pattern to birds in urbanizing environments
Urbanization reduces the quantity of native vegetation and alters its local structure and regional spatial pattern. These changes cause local extirpations of bird species associated with nativeExpand
Wildlife responses to pedestrians and dogs.
As participation in outdoor recreational activities escalates, land managers struggle to develop management policies that ensure coexistence of wildlife and recreation. How- ever, this requires anExpand
Common Raven Activity in Relation to Land Use in Western Wyoming: Implications for Greater Sage-Grouse Reproductive Success
Abstract. Anthropogenic changes in landscapes can favor generalist species adapted to human settlement, such as the Common Raven (Corvus corax), by providing new resources. Increased densities ofExpand
Tourism, mountain huts and distribution of corvids in the Bavarian Alps, Germany
The results suggest that corvids opportunistically adjust their range use to the availability of resources offered by tourism, and mountain huts and other places frequented by humans may contribute to an increased carrying capacity for corvid at higher elevations. Expand
The Impact of Nature-Based Tourism on Bird Communities: A Case Study in Pallas-Yllästunturi National Park
The results of the study suggest that the current recreation pressure has not caused substantial changes in the forest bird communities within the Pallas-Yllästunturi National Park and it is suggested that the abundances of urban exploiter species could be used as indicators to monitor the level and changes of urbanization and recreational pressure at tourist destinations.

Abstract We assessed the effect of campgrounds on American crow (Corvus brachyrhynchos) populations on the Olympic Peninsula in Washington, USA, because crows are potential nest predators for marbledExpand
Abstract Widespread conversion of deciduous forests to agriculture in the midwestern United States has resulted in landscapes whose remaining native habitats are highly fragmented, withExpand
Space use by Common Ravens in Marbled Murrelet nesting habitat in Northern California
Little is known about space use by Common Ravens (Corvus corax) in coastal old-growth redwood (Sequoia sempervirens) forests in northern California despite their identification as nest predators ofExpand
Corvid Density and Nest Predation in Relation to Forest Fragmentation: A Landscape Perspective
The Hooded Crow was the most important species in the corvid family, causing increased predation pressure close to forest-farmland edges and in small forest fragments surrounded by agricultural land. Expand
