We compared avian use of 39 restored and 39 natural wetlands in North and South Dakota during spring and summer of 1997 and 1998. Wetlands were widely distributed, but restored- and natural-wetland pairs were from the same geographic locale and had similar characteristics, including wetland size. We conducted paired comparisons between restored and natural wetlands for wetland-bird density, waterfowl-breeding pairs, and wetland-avian abundance, species richness, and diversity. We also compared abundance, species richness, and diversity of birds on upland areas adjacent to wetlands. Canada goose (avian scientific names in Appendix A), mallard, redhead, and ruddy duck had higher densities on restored wetlands. We failed to detect differences in overall avian abundance, species richness, or diversity between restored and natural wetlands. We conclude that restored wetlands in the Prairie Pothole Region supported similar avian communities with equal or higher abundances than those of natural wetlands.

Interior, freshwater wetlands of the United States include potholes, marshes, swamps, bogs, fens, and riparian wetlands. These wetlands are diverse in form and function and have unique properties that make them different from both terrestrial and aquatic ecosystems. The biological complexity and ecological functions of wetlands make these ecosystems among the most valuable and productive on earth (Mitsch and Gosselink 1986:11). For example, wetlands are valued for functions such as surface-water storage, groundwater recharge, removal and transformation of nutrients, and soil stabilization (Greeson, Clark, and Clark 1979; Smith et al., In Preparation). Wetlands also provide habitat for fish and wildlife, including a third of the nation's threatened and endangered species (National Research Council (NRC) 1992a:265). Despite their ecological importance, wetlands have been lost and degraded at alarming rates. An estimated 53 percent of the original 89.4 million ha of wetlands in the lower 48 States were lost by the mid-1970s (Dahl 1990), and losses continued at approximately 117,000 ha per year from the mid-1970s to the mid-1980s (Dahl and Johnson 1991). The national policy has changed gradually over the past 20 years from 'encouraging the draining and filling of 'worthless swampland' to recognizing the many benefits provided by wetlands and considering them a valuable national resource' (Ratti and Kadlec 1992:1).

... The common pheasant (ring-necked pheasant) was originally found in large parts of Asia and south-eastern Russia, eastwards from the Caucasus and Caspian Sea. Following introduction to England and France around a thousand years ago, pheasants have spread throughout Europe and have also been introduced to New Zealand, North America (including the Hawaiian Islands), Chile and other locations (Giudice et al., 2022). The birds bred in captivity for release are mainly hybrids between the subspecies Phasianus c. colchicus and P. c. torquatus, but P. c. mongolicus and P. c. karpowi are also being used in the breeding stock (Bevanger, 2005). ...

... c. torquatus): Adult males, 240-253 mm; adult females, 208 mm (Johnsgard, 1989). Adult males (various racial populations), 235-258 mm; adult females, 210-220 mm (Giudice and Ratti, 2001 (Johnsgard, 1975a). Trautman (1982) tabulated a great deal of weight data on birds from South Dakota, and reported an annual average adult male weight of 44.5 oz. ...

... Common Pheasants Phasianus colchicus (hereafter pheasant) produce eggshells with an olive-brown ground colour that is mainly composed of a high protoporphyrin-low biliverdin mixture (Kennedy & Vevers 1976). Pheasants lay clutches of 7-15 eggs on a granivorous diet low in calcium and may produce a new clutch up to five times per breeding season (Guidice & Ratti 2020), although there is evidence that reduced calcium limits egg production in females (Greeley 1962, Chambers et al. 1966, Jones et al. 2010. We collected eggs from pheasants on seven diets differing in calcium percentage (0.2-4.5%). ...

... Despite elimination and alteration of extensive areas, wetlands in the PPR remain important to many wildlife species, although it is not well understood how some wildlife respond to altered characteristics of wetlands dominated by invasive vegetation or to efforts to restore native vegetation communities (National Research Council 1992, Ratti et al. 2001, Pulfer et al. 2014. ...

... The genus Alectoris consists of 7 closely related interfertile species and 24 subspecies, including A. chukar [4]. A. chukar is a very distinctive species, native to Asia but have introduced to other regions of the world including North America, Canada, Great Britain, and New Zealand by allopatric distribution [5]. ...

... Incorporating at least some forest into an agricultural landscape is known to support game wildlife including northern bobwhite quail, wild turkey, and white-tailed deer (Brennan, 1999;McRoberts et al., 2014). Incorporating at least some grassland into an agricultural landscape supports game wildlife including northern bobwhite quail and ring-necked pheasant (Brennan, 1999;Giudice and Ratti, 2001). Prairie pothole wetlands are important for birds, especially water nesting bird species (Best et al., 1995;Hunter Jr., 2005). ...

... GTRs should not be flooded during consecutive years in the same area because of the potential impacts to regeneration. Rather, Giudice and Ratti (1995) recommend flooding of GTRs once every 2 to 3 years to simulate natural events, promote nutrient cycling, aid seedling establishment, and prevent a species shift toward a more mesic community than would otherwise develop. Survival and regeneration of herbaceous plant populations of concern should be monitored in established plots following purposefully flooded verses unflooded dormant seasons to determine the influence on the viability of the seedbank (Kirkman and Sharitz 1994). ...
