    Riparian forests play multitude of fundamental roles in the preservation of the environment. In order to assess its conservation state, different inde Invasive saltcedar species have replaced native riparian trees on numerous river systems throughout the western United States, raising concerns about how this habitat conversion may affect wildlife. For periods ranging from 2 to 11 yr, I used live-trapping to monitor small mammal populations in paired saltcedar and native riparian woodlands at four sites in western Nevada and eastern

Birds as Wetland Indicators INTRODUCTION Wetland and riparian areas in the arid western United States support a disproportionate diversity of aquatic and terrestrial wildlife, and are critical to the maintenance of the region’s water resources (Knopf et al.Keddy ).

A few studies have identified birds as useful means for evaluating the performance of riparian restoration projects (Kus ; Kus & Beck ), and birds in gen-eral may be good indicators of environmental condition (Carigan & Villard ).

Biophysical setting models have been developed for most major (dominant) vegetation types. These models describe the vegetation, geography, biophysical characteristics, succession stages, disturbance regimes, and assumptions for each vegetation type (Havlina et al, ) Model outputs showed that riparian condition has been at least moderately impaired across ≈70% of the streams and rivers in Utah and ≈49% in the CRB.

While continued efforts are underway to model vegetation changes that account. This study assessed the relationship among land use, riparian vegetation, and avian populations at two spatial scales.

Our objective was to compare the vegetated habitat in riparian corridors with breeding bird guilds in eight Rhode Island subwatersheds along a range of increasing residential land use. Riparian habitats were characterized with fine-scale techniques (used field transects to   Livestock grazing is the most prevalent land use practice in the western United States and a widespread cause of degradation of riparian vegetation.

Riparian areas provide high-quality habitat for many species of declining migratory breeding birds. We analyzed changes in vegetation and bird abundance at a wildlife refuge in southeastern Oregon We counted birds within a 25 m radius surrounding the observer in four plots, covering an area 60 m × 50 m ( m 2) each in the four vegetation types (i.e., grassland, woodland, riparian, and shrubland).

These vegetation types were selected because they represented the general vegetation composition in Mole National ://
