Description:
Nine created wetlands were paired with nine natural wetlands and compared for species composition, species diversity, wetland function and other site characteristics. Results from comparison of species composition and species diversity indicated that some differences existed between the created and natural sites. However, because differences also existed in the data collected from different teams sampling the same site, the created and natural site differences were confounded. n addition to the possible heterogeneity within the sites, low replicability between he teams may have been due to insufficient training prior to field work, different botanical skill levels, or the subjectivity of some of other data collection forms. A comparison of species composition also found some similarities with respect to the native/introduced and indicator status of the species found at the created and natural sites. enerally, the species classified as obligate, facultative wetlands, and wetland were native to the Pacific Northwest, while those species classified as facultative upland and upland were introduced.
