Aquatic Habitats and Communities

Science Center Objects

The Pacific Northwest includes a patchwork of public lands managed by numerous state and federal agencies. Our research informs and supports these agencies as they conserve and manage native amphibian species, including pre- and post-treatment assessment, decision support, long-term monitoring, population translocation, and habitat restoration.


Many of the systems we work in have altered hydrological regimes, so a focus of our research is understanding native species relationships with timing and amount of water. Examples are studies of amphibian distribution and abundance relative to different water management scenarios and relationships with active beaver dams.
