The Union Bay Natural Area (UBNA) in Seattle in the US state of Washington , also known as Union Bay Marsh, is the rest of the renatured area after the construction of the University Village Shopping Center, the sports facilities of the University of Washington (UW) and its main parking lot (E1 ) populated earlier Union Bay and Union Bay Marsh. It is on the east end of the main UW campus, south of NE 45th Street and west of the Laurelhurst neighborhood. a Ravenna Creek is connected to University Slough (a drainage canal), creating a link between Union Bay and Lake Washington . b The drainage canal is one of three or four open bodies of water that connect to Lake Washington around Union Bay Marsh. The canal extends from NE 45th Street between the golf course and IMA Sports Field 1 south to the bay and past the Husky Ballpark baseball field (northeast of the IMA building). The drainage canal that carries the water from Ravenna Creek over the UBNA to Union Bay is also called University Slough .

Flora and fauna

The small green areas , modest ponds and the lakeshore of UBNA offer birds (such Ohrenscharben , Canada herons and eagles) retreats; Turtles and frogs can be seen. The UBNA is remarkable for its diverse habitats; this includes a lake of considerable size, small ponds with permanent water flow as well as temporary ponds, trees, prairie areas and swamp holes. The transitions between these habitats are particularly attractive to bird watchers who have identified more than 150 species of birds.

history

The canal or delta was part of the Union Bay Marsh renaturation project of a wetland that was drained by the opening of the Montlake Cut in the course of the construction of the Lake Washington Ship Canal (1916) and backfilled by the excavation created, home of JP Patches, of a popular television clown who lived here from 1958 to 1981. c Previously designated the area as Mont Lake Landfill, University dump, or Ravenna Landfill and was supported by the City of Seattle from 1911 to 1966 as household waste used -Deponie for residential and industrial waste. ( Landfills opened in 1911, 1920, and 1926, and closed to the public in 1966 or 1967.) Five years later, the landfills were covered with 2 ft (0.6 m) of clean soil . Most of the area was covered by the University Village (1956), the UW sports facilities, buildings and the main parking lot (E); the rest is the UBNA generally "the fill" ( German  landfill ) called.

Renaturation

Prior to the sinking of Lake Washington in 1916, Ravenna Creek and Yesler Creek flowed into the delta north of where the canal begins today, and the areas through which the canal would then flow are below Union levels Bay. The Burke-Gilman Trail follows the route of the Seattle, Lake Shore and Eastern Railway along the original shores of Union Bay behind the UW power station and University Village. The renaturation work was completed in 2006 with a project that leads the partially drained Ravenna Creek to Union Bay by running it underground to the canal, so that the upper section of a largely stagnant flowing water to the outflow to one of Seattle's partially renatured urban streams became. The further drainage from the southeast of Ravenna Park to the UW and the UBNA was prevented by the owners of the University Village.

UBNA is owned by Washington State and is held under the aegis of the University of Washington; access is regulated. Parts of the area are open during park hours, while access to other sections is undesirable. For some of these regions this only applies seasonally, e.g. B. for biotope or species protection.

Many renaturation projects are carried out in the area of ​​the UBNA. The elimination of invasive species such as the Armenian blackberry ( Rubus armeniacus ) and the common bindweed ( Convolvulus arvensis ) is part of an ongoing effort to bring the area closer to a natural state. Volunteers play a major role in this.
