CEGL003294 Malus fusca - (Salix hookeriana) / Carex obnupta Shrub Swamp
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Oregon Crabapple - (Dune Willow) / Slough Sedge Shrub Swamp
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs in depressions in both deciduous and coniferous forests. Several examples of this association have been observed in the field but only one plot has been sampled. All trees are peripheral to the wetlands. The most typical expression known to the author is a dense, monotypic stand of Malus fusca with a monotypic understory of Carex obnupta. Depending on hydroperiod, the understory ranges from nearly 100% cover of Carex obnupta to very low cover of any other vegetation because of prolonged seasonal ponding. The plot reported here also contains Salix geyeriana and Spiraea douglasii. The association may have been more widespread historically, as large expanses of swamp vegetation once occurred in the northern Willamette and Tualatin valleys. These wetlands have not been sampled adequately.
