||The use of wetland treatment systems (WTS) for treating municipal wastewater is increasing in the United States, but little is known about the ability of these systems to duplicate or sustain wetland functions. The pilot study was designed to examine methods and the usefulness of various wetland indicators for assessing the wildlife habitat quality in six WTS sites throughout the United States and to identify any major differences in indicator values between WTS and non-WTS. The report focusses on two of the sites, one located in east-central Arizona and one in the Carson Valley in Nevada. Habitat indicator data collected in the field, as well as existing data, were summarized and compared with ranges of values for the same indicators from non-WTS. Of the indicators measured, vegetation, invertebrates, site morphology, and birds appear to be the most promising for assessing and monitoring habitat quality in terms of reliability of data.
