Aim We examined the influences of regional climate and land‐use variables on mallard (Anas platyrhynchos), blue‐winged teal (Anas discors), ruddy duck (Oxyura jamaicensis) and pied‐billed grebe (Podilymbus podiceps) abundances to inform conservation planning in the Prairie Pothole Region of the United States. Location The US portion of Bird Conservation Region 11 (US‐BCR11, the Prairie Potholes), which encompasses six states within the United States: Montana, North Dakota, South Dakota, Nebraska, Minnesota and Iowa. Methods We used data from the North American Breeding Bird Survey (NABBS), the National Land Cover Data Set, and the National Climatic Data Center to model the effects of environmental variables on waterbird abundance. We evaluated land‐use covariates at three logarithmically related spatial scales (1000, 10,000 and 100,000 ha), and constructed hierarchical spatial count models a priori using information from published habitat associations. Model fitting was performed using a hierarchical modelling approach within a Bayesian framework. Results Models with the same variables expressed at different scales were often in the best model subset, indicating that the influence of spatial scale was small. Both land‐use and climate variables contributed strongly to predicting waterbird abundance in US‐BCR11. The strongest positive influences on waterbird abundance were the percentage of wetland area across all three spatial scales, herbaceous vegetation and precipitation variables. Other variables that we included in our models did not appear to influence waterbirds in this study. Main conclusions Understanding the relationships of waterbird abundance to climate and land use may allow us to make predictions of future distribution and abundance as environmental factors change. Additionally, results from this study can suggest locations where conservation and management efforts should be focused.

“…The averaged data of all sites were used to determine the bird community every month Fig. 4 The number of wintering water birds significantly decreased in the newly formed lakeside from 2006 to 2011 foraging behavior, roosting locations, species composition and populations of water birds (Wan et al 2001;Armitage et al 2007;Forcey et al 2007). Studies confirmed that wetlands with more vegetation species and shallow water tend to attract more birds (Lindegarth and Chapman 2001;Hoover 2006;Riffell et al 2006;Cui et al 2009), and food is the most important factor that influence the distribution of water birds (Erwin 1983;Stillman et al 2010;Reid et al 2013).…”

Whether dam impoundment for water resource purposes improves wetland ecosystems is heavily disputed. In this study, we investigated the effects of dam impoundment from 2006 to 2011 on wetland plant communities and wintering water birds in Lashi Lake, a typical closed wetland in Northwest Yunnan, China. The surface area of the water body increased from 933 hm 2 before impoundment to 1262 hm 2 after impoundment; the area of meadows and emergent, submerged and floating vegetation increased from 1006 to 1149 hm 2 . After the dam impoundment and with the rising water level, formerly dominant plant communities, such as Com. Phragmites australis, Com. Potamogeton pectinatus and Com. Nymphoides peltatum, disappeared. New communities, such as Com. Polygonum hydropiper, Com. Acorus calamus and Com. Leersia hexandra, rapidly expanded into the newly formed lakeside. During these changes, the species and number of wintering water birds slightly increased, but the populations and distributions of birds were altered. Some birds chose the newly formed lakeside as habitat, while others disappeared or decreased greatly. Notably, the major protected birds, such as species of Ciconia nigra, did not appear in the new area, and the species number of Grus grus decreased. The results showed that damming impacted wetland ecosystems. Given the importance and complexity of dam impoundment in alpine wetlands, the effects of food-chain modifications on plants, water birds, aquatic organisms, and humans could be extensive.
