Shaffer, J.A.; Oxborrow, B.; Parks, D.S.; Maucieri, D.G., and Michel, J., 0000. Linking marine ecosystem response to shoreline armor removal and large dam removals in the Elwha River and nearshore, Washington, USA. Journal of Coastal Research, 00(00), 000-000. Charlotte (North Carolina), ISSN 0749-0208. Large in-river dams and shoreline armor have...

In this paper we assess long-term trends and habitat changes to understand the relationships between coastal beaver (Castor canadensis), salmon, shoreline alterations, large-scale dam removals and nearshore ecological restoration. From this work we conclude that the removal of two large scale dams in the Elwha River has benefited beaver use of the...

This poster displays sampling results of beach topography and sediment grain-size distributions on intertidal beaches of the Elwha and Dungeness Drift-Cells before, during and after dam removal. All data are copyrighted and the author retains all rights to publishing of the data on this poster.

Coastal zones are important components of marine ecosystems that link upland and marine areas, and are often maintained by landslides, though these habitat forming processes are poorly understood. They are also often sites of commercial development, including mining, and restoration. In this ecosystem restoration project, we rapidly removed a large...

The nearshore is a critical zone for northeast Pacific Ocean fish communities, including ecologically and culturally important salmon species. The largest dam removal in the world was recently completed on the Elwha River, with the goal of restoring fisheries and ecosystems to the watershed. The nearshore Elwha fish community was monitored monthly...

The spatial distribution and temporal variability of retreat rates of coastal bluffs composed of unconsolidated glacial deposits are of interest to landowners who occupy bluff-top properties as well as coastal resource managers who are responsible for protecting marine habitats such as forage fish spawning beaches that are dependent on bluff-derive...

Sediment processes of erosion, transport, and deposition play an important role in nearshore ecosystem function, including forming suitable habitats for forage fish spawning. Disruption of sediment processes is often assumed to result in impaired nearshore ecological function but is seldom assessed in the field. In this study we observed the sedime...

Our natural environment provides things we need to survive — breathable air, drinkable water, food, security from flood and storm, and stable atmospheric conditions. Natural systems also provide things essential for every economy to survive, such as oxygen, water and raw materials. Ecosystem services provide substantial economic value that, when ma...

A medium scale landslide (2153 m3) deposited sediment on to a intertidal beach on the north side of Point Williams, Seattle, Washington on 4 April 1991. Within 23 days of the slide, high tides and rain carried 77% of the sediment to nearshore waters and north through a seasonal kelp bed immediately adjacent to the slide area. Transects were placed...

The Angel Fire of September, 1987 caused extensive damage to second growth forest in the south fork drainage of Cow Creek, 55 km northeast of Grant's Pass, Oregon, USA. The fire was characterized by a high-intensity burn over areas of steep topography. The areal distribution of soil hydraulic properties in a small, tributary watershed following hig...
