Examining Restoration Success after Ten-years of the Green Seattle Partnership: Implementation and Results of the Phase 4 Verification

By Derek Buckner, Kern Ewing, Jim Fridley, and Lisa Ciecko

In 2005 the Green Seattle Partnership (GSP) was established as a twenty-year restoration plan for 2,500 acres of urban forests. After ten years an analysis was made to determine which areas might move into the Phase 4 of maintenance.  A logistic regression showed that the latest monitoring data on invasive cover and understory cover were significantly correlated to Phase 4 status, while five other monitoring categories were not significantly correlated.

Keywords: restoration ecology , ecological verification, logistic regression, invasive cover, understory cover, regeneration

Thatcher Bay Nearshore Restoration Monitoring

By Thomas Peterman, Kern Ewing, Jim Fridley, and Sandy Wyllie-Echeverria

Monitoring nearshore sites that have undergone restoration work after wood waste contamination is critical for assessing restoration objectives. The project had four elements that may be used as a model for future nearshore restoration efforts: assessing intertidal sediment characteristics, evaluating benthic macroinvertebrate assemblages, surveying for forage fish spawning activity, and observing for the potential spread of native eelgrass (Zostera marina) into the restoration site.

Keywords:  nearshore restoration, monitoring, sediment, ecosystem functions, habitat restoration, wood waste

Designing and Installing an Agricultural Hedgerow to Restore Native Pollinator Habitat

By Nicolette Neumann, Kern Ewing, Sarah Reichard and Jim Fridley

Many species of pollinators are experiencing declines due to a variety of environmental pressures, including habitat loss, which has had impacts on agricultural production. Restoring habitat adjacent to farms by planting hedgerows composed of native species that provide ample forage, nutrients, and nesting sites can help boost populations of wild, native pollinators which will in turn enhance crop yield.”

Ballard Green Spaces Project: A Survey of the Ballard District for Ecological Restoration and Habitat Enhancement Opportunities

By Theresa Yoder, Kern Ewing and Jim Fridley

Growth and development is a natural part of urban areas, but it has adverse effects on natural ecosystems, causing fragmentation or complete loss of these areas over time. Before urban restoration projects begin appropriate sites must be identified and ownership details compiled.

Keywords:  habitat restoration, ecosystem fragmentation, natural area survey, green spaces, urban development

Prairie rain garden design and installation project

By Malcolm Howard, Kern Ewing and Jim Fridley

Urban development and its attendant increase in stormwater has led to water quality degradation and an increase in the cost of infrastructure to handle flows. Detention close to the point of generation addresses these issues.

Amphibian corridor: a frog and salamander habitat restoration project

By Kathleen Walters, Kern Ewing and Jim Fridley

Amphibian decline has been observed in developing areas globally. Restoration of habitat in corridors improves connectivity and increases the effective habitat of these indicator species.
