Programs and Projects


Maintaining Faunal Diversity in Forested Ecosystems of the Coastal and Intermountain West

Ecology of Species of Concern

The management of natural resources continues to require an understanding of the ecology of individual species and higher taxa of conservation concern.

Understanding Mechanisms of Population decline

Worldwide loss of biodiversity from a wide variety of anthropogenic causes continues at a rapid rate and manifests itself locally via decline of individual wildlife populations. Understanding the ecological roles of target organisms is necessary to demonstrate their importance to ecosystem function and to discern the mechanisms and impacts of their decline. Unit scientists conduct work to identify emerging and existing threats to conservation of individual taxa groups and use predictive models and cause-effect approaches to understand species resilience under differing threat levels.

Special Ecological Considerations for Relict Taxa

Relict fauna are animals that belong to groups which formerly contained a large number of widely distributed species but which are now limited to few species or specialized ecological niches. The study these ancestral species can help provide important insights into ecosystem integrity and response of animal populations to changes in conditions that occur over relatively long time periods (e.g., climate change). Unit scientists take advantage of the relatively stable, humid climates within the Klamath Bioregion to conduct work on these important and fascinating creatures.
