Wetland restoration
View of the wetlands from within the building

EWEB's Roosevelt development includes approximately 14 acres of wetlands that have been restored and enhanced. These wetlands have been neglected over the years and the new development is intended to maximize natural habitat and also provide water efficient landscaping.

This restoration of the land is a visible expression of EWEB's environmental stewardship and provides an example of how to develop an industrial site with wetlands in Eugene.

EWEB's wetlands include several different habitat zones that support a variety of plants and animals.

EWEB wetlands habitat zones

Habitat zone Description Plants and animals that may be found at EWEB site
Snag Snags provide perches for raptors and nest sites for cavity-nesting birds. Insects in the wood provide food birds. Trees that fall to the ground provide habitat for snakes, lizards and other animals.
  • Cottonwood Snag
  • Red shafted Flicker
  • American Kestrel
Shrub wetland Shrubs provide a buffer for other wetland areas. They help to control erosion and filter pollutants from surface runoff. The shrubs also provide protective cover from predators, as well as homes and foraging areas for birds.
  • Redosier Dogwood
  • Sitka Willow
  • Nootka Rose
  • Orange Crowned Warbler
  • Spotted Towhee
Wet prairie The wet prairie is one of the most endangered habitats in Oregon. These areas dry out in the summer, appearing as open, grassy landscapes. In the wet months, the soil becomes saturated, and low areas fill with water, attracting shorebirds and waterfowl.
  • Camas
  • Garter Snake
  • Kildeer
Emergent (ponded) wetland A clay layer under the topsoil in the emergent wetland and the wet prairie slows water seepage into deeper soils. In the past, when this area was used from farming, plowing and filling eliminated the low spots, or hollows in the land. EWEB reintroduced these areas as part of its restoration effort during the building of the Roosevelt Operations Center.
  • Great Blue Heron
  • Mallard
  • Calicoflower
  • Popcorn Flower
Forested wetland The plants in this zone like to live in areas that flood frequently but do not always have standing water.
  • Red Legged Tree Frog
  • Wilson's Warbler
  • Slough Sedge
  • Oregon Ash
Upland buffer Before European and Asian American settlers arrived in the Eugene area, the Kalapuya used fires to control woody vegetation and maintain both wet prairie and open grassy areas with scattered trees. These open areas were designed to approximate the habitat zones that are believed to have existed on the Roosevelt Operations Center property at that time.
  • Ponderosa Pine
  • Western Scrub Jay
  • Douglas Fir
  • Coyote
  • White Oak
