Patterns of habitat use by breeding birds were studied in cottonwood riparian forests along 100 km the South Fork Snake River southeastern Idaho, United States, from 1991 to 1994. A hierarchical approach was used examine at three spatial scales: microhabitat (local vegetation characteristics), macrohabitat (cottonwood forest patch and landscape (composition patterning surrounding [matrix] types land uses). This paper addresses a series predictions about species' distributions that...

Prescribed fire is a management tool used to reduce fuel loads on public lands in forested areas the western United States. Identifying impacts of prescribed bird communities ponderosa pine (Pinus ponderosa) forests necessary for providing land agencies with information regarding effects reduction sensitive, threatened, and migratory species. Recent developments occupancy modeling have established framework quantifying practices wildlife community dynamics. We describe Bayesian hierarchical...

Mountain pine beetle (Dendroctonus ponderosae) (MPB) outbreaks are increasingly prevalent in western North America, causing considerable ecological change (Pinus spp.) forests with important implications for wildlife. We reviewed studies examining wildlife responses to MPB and postoutbreak salvage logging inform forest management guide future research. Our review included 16 describing outbreak relationships 89 bird species 6 11 mammalian species, but no of reptiles or amphibians. that...

The effects of landscape fragmentation on nest predation and brood parasitism, the two primary causes avian reproductive failure, have been difficult to generalize across landscapes, yet few studies clearly considered context spatial scale fragmentation. Working in river systems fragmented by agricultural rural-housing development, we tracked nesting success parasitism ;mt2500 bird nests 38 patches deciduous riparian woodland. Patches both were embedded one local contexts (buffered from...

We monitored the nest densities and survival of seven cavity-nesting bird species, including four open-space foragers (American Kestrel [Falco sparverius], Lewis's Woodpecker [Melanerpes lewis], Western Bluebird [Sialia mexicana], Mountain [S. currucoides]) three wood-foragers (Hairy [Picoides villosus], Black-backed [P. arcticus], Northern Flicker [Colaptes auratus]), after two wildfires (one partially salvage-logged one unlogged) in western Idaho from 1994–2004. estimated relationship...

Abstract We use the historical presence of high‐severity fire patches in mixed‐conifer forests western United States to make several points that we hope will encourage development a more ecologically informed view severe wildland effects. First, many plant and animal species use, have sometimes evolved depend on, severely burned forest conditions for their persistence. Second, evidence from history studies also suggests complex mosaic conifer was common historically West. Third, maintain...

Recently burned forests in western North America provide nesting habitat for many species of cavity-nesting birds. However, little is understood about the time frame and variables affecting occupancy postfire habitats by these We studied factors influencing reuse nest cavities from 1–7 years after fire two sites Idaho during 1994–1999. Tree were used 12 cavity nesters that classified original occupant (strong excavator, weak or nonexcavator) 385 cavities. logistic regression to model strong...

Lewis's Woodpecker (Melanerpes lewis) has been characterized as a "burn specialist" because of its preference for nesting within burned pine forests. No prior study, however, demonstrated the relative importance crown-burned forests to this woodpecker species by examining reproductive success in different forest types. We studied breeding Woodpeckers cottonwood (Populus fremontii) riparian patches Colorado and ponderosa (Pinus ponderosa) Idaho compare their success, productivity, potential...

Abstract We monitored the nest densities and survival of seven cavity-nesting bird species, including four open-space foragers (American Kestrel [Falco sparverius], Lewis's Woodpecker [Melanerpes lewis], Western Bluebird [Sialia mexicana], Mountain [S. currucoides]) three wood-foragers (Hairy [Picoides villosus], Black-backed [P. arcticus], Northern Flicker [Colaptes auratus]), after two wildfires (one partially salvage-logged one unlogged) in western Idaho from 1994–2004. estimated...

Abstract Salvage logging practices in recently burned forests often have direct effects on species associated with dead trees, particularly cavity‐nesting birds. As such, evaluation of postfire management nest survival rates cavity nesters is necessary for determining conservation strategies. We monitored 1,797 nests 6 bird species: Lewis's woodpecker ( Melanerpes lewis ), hairy Picoides villosus black‐backed P. arcticus northern flicker Colaptes auratus western bluebird Sialia mexicana and...

ABSTRACT Models of habitat suitability in postfire landscapes are needed by land managers to make timely decisions regarding timber harvest and other management activities. Many species cavity‐nesting birds dependent on for breeding aspects their life history responsive activities (e.g., harvest). In addition, several cavity nesters designated as at risk. We compare the ability 2 types models distinguish between nest non‐nest locations 6 bird (Lewis's woodpecker [ Melanerpes lewis ],...

Riparian woodlands of aspen (Populus tremuloides) provide valuable breeding habitat for several cavity-nesting birds. Although anecdotal information this is available Lewis's Woodpecker (Melanerpes lewis), no study has previously examined the importance to species' biology. From 2002 2004, we monitored 76 nests in riparian south-central Idaho describe nest-site characteristics and estimate nests' survival. We quantified vegetation at nest sites randomly selected other determine features...
