Research at the NWRC Corvallis field station is focused on developing
feasible tools and strategies to resolve problems associated with wildlife
damage to forest resources. Reforestation efforts are greatly hindered
because of the cutting and gnawing of seedlings by a variety of rodents,
and browsing by ungulates. Girdling of older trees also causes substantial
mortality or subjects trees to subsequent disease and insect infestations.
Wildlife, particularly mammalian herbivores, can impede attempts to
establish native plants to increase forest diversity, improve riparian
areas, re-vegetate disturbed sites, restore endangered or threatened
plants, or to create or improve habitat for wildlife. Foraging wildlife
can be extremely detrimental if animals browse on plants before seedlings
are well established, or if foraging is continuous or intense. Native
plant projects are often destined to fail because there are limited
foraging options for wildlife at planting locations.
At present, the research at the field station focuses
on efforts to alleviate damage inflicted by bear,
and elk, mice, mountain
and voles. Nonlethal management measures are a priority, and applied
studies are conducted to develop new products (e.g., repellents, attractants,
delivery systems), assess efficacy, nontarget impacts, and long-term
consequences of new or existing management techniques, and investigate
forest management options to reduce resource vulnerability.
Because new tools cannot be created without first having a fundamental
understanding of the problem, research of a more basic nature also
is conducted. Station personnel conduct studies to elucidate the role
of chemical senses and experience on foraging behaviors, and perform
field research to clarify the environmental and ecological factors
influencing the occurrence, dispersal, and population densities of
targeted species. Results are used by a broad array of managers developing
management plans protecting forest resources from damage by wildlife.
The station's expertise and productivity are further enhanced by collaborative
efforts within NWRC, as well as, with universities, state and federal
agencies and the private sector. Additionally, facilities available
through collaborative scientists further enhance Olympia scientists'
abilities to conduct additional animal research and laboratory analysis.
