Seed Collection in Oregon’s Remaining Coastal Prairies

Starting in 2015, IAE was awarded an opportunity to engage in collecting seed of a diversity of plant species from remnant prairies on the Central Oregon Coast. The project will support ongoing restoration efforts for the Oregon silverspot butterfly (OSB) at Nestucca Bay National Wildlife Refuge near Pacific City, and will benefit other restoration sites […]

Bartonberry outplanting in Hells Canyon

Over the last two years, the Institute for Applied Ecology (IAE) has been developing propagation protocols to grow Bartonberry (Rubus bartonianus) from seed and cuttings, so that it may be reintroduced to the historic range, to maintain its historic global distribution. In addition to IAE staff, Matt Bahm, Erin Gray, Denise Giles-Johnson, and Meaghan Petix, […]

A Day in the Dunes

Last week the Conservation Research team headed out to the central Oregon coast for one of our first trips of the 2016 season! We met up with one of our partners, Marty Stein (USFS), and went to four sites within the Suislaw National Forest – Tahkenitch, Overlook South, Overlook North, and Siltcoos (from south to […]

Welcome 2016 IAE/NPSO Interns!

This past week we welcomed our new crew of IAE/NPSO interns: Liza Holtz, Sarai Carter, and Ari Freitag! Liza is absolutely thrilled to be a Conservation Research Intern with IAE! She received a B.S. in Natural Sciences with an emphasis in Biology from the University of Puget Sound (2013). During her undergraduate studies she researched […]

What do Taylor’s checkerspot caterpillars eat?

This has been a boom year for Taylor’s checkerspot, an endangered species in Oregon’s Willamette Valley.  The two remaining populations in the state have both shown great numbers – over 1000 butterflies each – and at least some of this appears to be due to strong land stewardship by Benton County Natural Areas and Parks […]

Table Rocks Rocks!

For our first trip of the field season, we visited Table Rocks outside of Medford, Oregon to study Limnanthes pumila ssp. pumila, or dwarf woolly meadowfoam, a threatened endemic species that relies on vernal pool habitat. Table Rocks consists of two plateaus formed by volcanic activity and shaped by erosion. The trails up to the plateaus wind through oak savanna which is home to many different species, including Cooper's hawk, turkey vulture, lark sparrow, and wild turkey that we observed on our hikes. Once you reach the plateaus, you are surrounded by a magnificent wildflower display and a plethora of busy pollinators, and can enjoy a spectacular view of Mount McLoughlin.

We really enjoyed getting to know each other on our first trip and learning about the vernal pool ecosystems at Table Rocks!

Conservation Research Adventures to the Desert

In June we said goodbye to our Corvallis western Oregon home and set out for a long day of traveling to Vale, Oregon on the eastern part of the state to monitor Astragalus mulfordiae, or Mulford’s milkvetch. Although the journey was long, it was a beautiful sight to watch the greens of the Cascades turn […]

The Great Fork Migration of 2015

For sometime now, the fork population at the Institute for Applied Ecology has enjoyed a relatively stable and consistent biannual migration, where these lovely eating utensils disappear for some months usually correlating with the start of the field season, and return with the end of the field season. This season however has been markedly different […]

Adaptive Restoration Efforts in Willapa Bay!

In June we traveled to the north coast by Astoria, OR and Long Beach, WA to assess the health and restoration potential at several different coastal prairie sites. Three of the five sites were located on land managed by the North Coast Land Conservancy, a non-profit that tackles conservation projects from the Columbia River south to Lincoln City. The other two sites are located on land owned by the National Park Service and U.S. Fish & Wildlife Service. The ultimate goal of this project is to evaluate the effects of adaptive restoration techniques on coastal prairie. The results of this project will provide useful information for future restoration efforts of coastal prairie, which is native habitat for the Oregon silverspot butterfly. In order to research the best adaptive management methods for prairie restoration, three techniques and a control were established: herbicide, soil inversion, and soil removal. The success of each restoration method is evaluated by collecting plant community data in all research plots every year. Within each plot we estimated percent cover of all plants occurring in four square meters. The plot photos are pictured below:

Control: These plots are established without any treatments but are exposed to the same conditions (weather, climate, herbivory, etc.) to create a basis for comparison with other treatments. Photo credit: Emma MacDonald

Topsoil removal: The entire nutrient rich top layer (essentially all organic material) was excavated from these plots leaving a sandy nutrient poor layer for new plants to colonize. Photo credit: Connor Whitaker

Topsoil Inversion: Vegetation and soil in these plots were turned over so they mimicked dune-soil conditions where nutrient rich soil layers (topsoil) move under or over nutrient poor (sandy) layers over time. Photo credit: Connor Whitaker

Herbicide application: Glyphosate was applied to these plots to assess the effect herbicide has on native plant community composition by exterminating exotic species. Photo credit: Connor Whitaker

Microclimates and Mustard

For much of June, Connor Whitaker, from the CR intern group, has been working closely on projects with Erin Gray and Matt Bahm. Erin and Connor spent a week monitoring an experiment that investigates the effects of microclimate on Kincaid’s lupine (Lupinus oreganus); following this, Matt and Connor spent two weeks near the John Day National Monument, […]

Monitoring Lupinus oreganus! And swimming through poison oak

  The Conservation Research team recently journeyed down to Canyonville, OR to monitor the threatened Lupinus oreganus, or Kincaid’s lupine. Kincaid’s lupine is the host plant to the endangered Fender’s blue butterfly, meaning the butterfly lays its eggs on this plant. Since populations of Kincaid’s lupine have been declining recently due to rapid urbanization and […]

Greetings from Table Rocks

It’s been a crazy month filled with field work, lots of laughs, and a bit of poison oak (more on that in a blog to come)! Traveling back to a few weeks ago, however, we started our field season at Table Rocks. Table Rocks is a geological formation outside of Medford, OR, resulting from millions […]
