An image of snow-capped Mount Hood with a blanket of fog covering forest below.

Mount Hood is located 62 miles east of Portland, Oregon.  It is a stratovolcano.  It is located in the Mount Hood National Forest.  You might find salamanders living there.

Invite pollinators, like the Silvery Blue Butterfly (Glaucopsyche lygdamus), to your garden.  Dig up the lawn and add in some Asters or Claytonia.  Silvery Blue Butterflies can be found in flowery meadows, woodlands and in cities.  Ants tend the larvae!

Salamanders live coast to coast in North America.  Habitat destruction threatens their existence.  Keep an eye for them at temperate rainforests, coniferous forests, riparian zones and along alpine meadows along the rocky shores of lakes.

Our Role

The BPR staff works across the agency and with partners to help meet the agency’s land management and resource stewardship responsibilities. We help the agency carry out its conservation mission by helping to:

  • Protect, sustain, and improve the water and watershed resources and services.

  • Protect ecosystems by ensuring that proposed management activities promote conservation of biological diversity.

  • Restore deteriorated ecosystems to improve their health, diversity, and productivity.

  • Provide multiple benefits to people by enhancing ecosystem productivity, managing public access, and increasing public awareness

  • Improve organizational effectiveness through fostering a skilled and knowledgeable workforce, exhibiting collaborative decision making; helping to make the best science-based information available; and encouraging monitoring and evaluation to improve the effectiveness of our actions.

We work closely with our customers and partners in accomplishing our objectives. The health, diversity, and productivity of the water, wildlife, fish, and plant communities on National Forest System lands -- and opportunities for their use and enjoyment -- will be the measures of our success.

    Brett Roper, PhD (Aquatic Ecologist) of our National Stream and Aquatic Ecology Center, recently co-authored Did changes in western federal land management policies improve salmonid habitat in streams on public lands within the Interior Columbia River Basin? Environ Monit Assess (2019) 191:574, Brett B. Roper & W. Carl Saunders & Jeffrey V. Ojala Abstract of the Abstract: Historic management actions authorized or allowed by federal land management agencies have had a profound negative effect on salmon, trout, and char populations and their habitats. To rectify past failings, in the 1990s, federal agencies in the Interior Columbia River Basin modified how they conducted land management activities to foster the conservation of aquatic species. ... By understanding and accounting for how changes in stream conditions reflect improved land management policies and broader environmental trends, federal agencies will be better situated to make project level decisions that benefit aquatic resources.

  • David Merritt, PhD (Riparian Ecologist) and Lindsay Reynolds, PhD (Riparian Ecologist) of our National Stream and Aquatic Ecology Center, recently co-authored a paper with colleagues, Prepare river ecosystems for an uncertain future; As the climate warms, we can’t restore waterways to pristine condition, but models can predict potential changes ... in the journal Nature about globally imperiled rivers and a call to action for river scientists worldwide. Dr. Merritt summarizes, "We present a four-step plan toward reshaping the kind of science that we are doing to protect rivers and ideas for engaging the public in recognizing their functions and services to society and steps toward their conservation and recovery. It is a compelling article and has been picked up by news outlets on the West coast and in New Zealand." Oregon State University Press Release
