Monitoring

City of Rocks National Reserve and Craters of the Moon National Monument and Preserve are lands managed by the National Park Service that contain ecologically valuable stands of sagebrush and unique forest communities that are at risk due to wildfire and invasion by exotic annual grasses. We are working to determine the extent of invasion and to provide park managers with wildfire risk assessments...

Wildfires are increasingly destroying wildlife habitat in sagebrush ( Artemisia species) ecosystems, and managers need approaches to scope the pace and degree to which post-fire restoration actions can re-create habitat in dynamic landscapes. Sagebrush recovery takes a long time, and it can be difficult to anticipate restoration outcomes over large, diverse landscapes that have experienced decades...

The Elwha River – located on the Olympic Peninsula in Washington - is home to an iconic dam removal and ecosystem restoration project. The Elwha offers a unique setting to explore the ecosystem level effects of dam removal and river restoration because of its prominence, such as large sediment volume, several salmon populations, and pristine wilderness.

The Issue: Streamflow permanence refers to the probability that a stream will lose surface flow (become a dry channel), as well as the timing, duration, and frequency of drying. Patterns of streamflow permanence drive important decisions regarding forest management and other land uses. The Colville National Forest Land and Resource Management Plan (2019), for example, specifies riparian management...

The expansion of the bat fungal disease White-Nose Syndrome (WNS) to the Pacific Northwest is centered in western Washington. However, not much is known about bat distribution and activity in and around Washington’s National Parks.

Fire rehabilitation programs have existed within federal agencies since the early 1960s. The U.S. Forest Service and Bureau of Land Management are the largest users of emergency stabilization and rehabilitation (ES&R) funds, but these agencies only sporadically implement proposed monitoring and rarely use common protocols. As a result, it is impossible to draw scientifically credible conclusions...

The Land Treatment Exploration Tool provides a practical resource for managers who are planning restoration and rehabilitation actions on public lands. The tool generates a variety of spatial products while being user friendly for all levels of GIS expertise, even to those with little or no experience.

Flight facilitates comparatively rapid access to large areas, and the study of the movements of birds is essential for learning their relationships to their environment, and for managing the resources on which they depend and conserving the communities in which they live. Often the amount of space used by raptors varies with behavior associated with the birds’ ages and with the annual cycle. For...

This research largely involves developing and applying survey methods to gather and analyze data to study raptor population biology and population status. Results also provide land and wildlife managers with information about the general distribution and local occurrence of birds of prey. Most raptor species occur in low densities compared to other birds. Raptors are widely dispersed during much...

Restoration of aquatic ecosystems involves a broad spectrum of active and passive efforts. Passive efforts rely on natural recovery of ecosystems, such as land use practices that protect riparian zones and sources of wood and sediment that drive the geomorphic and associated biological functions in streams. Active efforts involve more direct intervention, usually applied to specific locations, to...

We study aspects of basic biology and ecology of predators to contribute to understanding ecosystems and to provide results that can be applied to the conservation of natural resources. Subject matter includes behavior and relationships of birds to features of their environment such as habitat, prey, and contaminants.

The Oregon spotted frog ( Rana pretiosa ) is a medium-sized anuran native to the northwestern United States. Body coloration ranges from brown or tan to brick red, usually overlaid with dark, ragged spots. Oregon spotted frogs can be distinguished from other native species by their relatively short hind legs, orange or red wash of color on underside of abdomen and legs, and upturned chartreuse...
