Forest and Rangeland Ecosystem Science Center (FRESC)
Home
Scientists from the Forest and Rangeland Ecosystem Science Center capitalize on their diverse expertise to answer scientific questions shaped by the environments of the western United States. We collaborate with each other and with partners to provide rigorous, objective, and timely information and guidance for the management and conservation of biological systems in the West and worldwide.
FRESC Research Teams
FRESC scientists, individually or collaboratively with partners, investigate high-priority questions about biological systems.

Effects of Red-cockaded Woodpecker Bottleneck and Current Management on Genetic Diversity
The red-cockaded woodpecker is a federally listed species that declined in the southeastern United States from approximately 1.6 million cooperative breeding groups historically to less than 3,500 groups by 1978 due to loss and degradation of habitat and fire suppression.
New Riverscape Model of Upstream Fish Migration
Survival and reproductive success of salmon and other diadromous fish depends on a return from the sea and upstream migration tens to thousands of miles through complex riverscapes to their birthplace.
When Are Eagles Likely to Collide with Aircraft?
Since the ban of DDT, bald eagle populations have rebounded to near-historic levels and aircraft strikes have increased since 1998. Wildlife-aircraft strikes are expensive and the large body size of the bald eagle increases the likelihood of aircraft damage and human injury when a collision occurs.

Three-dimensional partitioning of resources by congeneric forest predators with recent sympatry
Coexistence of ecologically similar species can be maintained by partitioning along one or more niche axes. Three-dimensional structural complexity is central to facilitating resource partitioning between many forest species, but is underrepresented in field-based studies. We examined resource selection by sympatric northern spotted owls (Strix...

Life-history model for sockeye salmon (Oncorhynchus nerka) at Lake Ozette, northwestern Washington—Users' guide
Salmon populations spawning in the Lake Ozette watershed of northwestern Washington were once sufficiently abundant to support traditional Tribal fisheries, and were later harvested by settlers. However, in 1974 and 1975, the sockeye salmon (Oncorhynchus nerka) harvest decreased to 0 from a high of more than 17,500 in 1949, thus stimulating...
Woodward, Andrea; Haggerty, Mike; Crain, Patrick Stream metabolism increases with drainage area and peaks asynchronously across a stream network
Quantifying the spatial and temporal dynamics of stream metabolism across stream networks is key to understanding carbon cycling and stream food web ecology. To better understand intra-annual temporal patterns of gross primary production (GPP) and ecosystem respiration (ER) and their variability across space, we continuously measured dissolved...
