“…These species are cemmonly associated with beaver ponds in the central Rocky Mountains (Frary 1954, Casagranda 1955, Peterson and Low 1977, Medin and Clary 1990. Breeding ducks comprised a higher proportion of total ducks during 1994 (77%) than was observed during another study of beaver ponds (43%) on the Laramie Range during 1993 (Brown 1994), This may be attributed to selection of ponds greater than 1000 m 2 in 1994 but inclusion of ponds that were 55 3540 m 2 in 1993.…”

“…Wetlands in the Rocky Mountains can provide habitat for migrating and breeding waterfowl (Peterson andLow 1977, Ringelman 1992). Among wetlands used by waterfowl in the Rocky Mountains are those formed by beaver (Castor canadensis Kuhl) when they build ponds (Medin and Clary 1990).…”

“…Beaver create or enhance habitat for duck breeding and brood rearing (Frary 1954, Stanton 1965, Renouf 1972, Nummi 1992) and for resting during migration (Peterson andLow 1977, Hair et al 1978). Duck use has been observed to be greatest among ponds actively used by beaver (Neff 1957, Nevers 1968, Collins 1972, Renouf 1972, Brown 1994.…”

We studied the use of beaver ponds and associated wetlands by ducks and waterbirds on the Laramie Range, Albany County, Wyoming, during 1994. Our goal was to identify physical habitat features of beaver ponds associated with use by migrating, breeding, and postbreeding ducks and other birds associated with aquatic habitats. Species richness of birds observed at beaver ponds was positively correlated with water surface area, area of shallow water, length of woody shoreline, and shoreline development (the ratio of shoreline length to the circumference of a circle of the same area as the water surface of the pond). Duck use (green-winged teal, mallard, and ring-necked duck) was positively correlated with water surface area, area of shallow water, and length of woody shoreline, but negatively correlated with the ratio of the area of submergent vegetation to water surface area. Use by riparian birds (red-winged blackbird and Brewer's blackbird) was positively correlated with water surface area, area of shallow water, area of emergent cover, and length of woody shoreline.

“…Other researchers (Renouf, 1972;Peterson and Low, 1977;Smith, 1992 Stream Order 7 1995) have examined the importance of beaver habitats to waterfowl; however, most have focused on specific habitat variables associated with beaver ponds and not the overall impact (e.g., numerical) beaver have on waterfowl populations across a broad region. While Gabor et al (1999) also focused on beaver pond management and demonstrated that different variables associated with beaver ponds can impact waterfowl, they also commented that breeding waterfowl densities on beaver ponds in southern Ontario are some of the highest within the province.…”

Beaver (Castor canadensis) are habitat‐modifying keystone species, and their activities broadly influence many other plants and animals. Beaver are especially important to waterfowl in the western U.S. where riparian and wetland habitats comprise less than 2 percent of the landscape yet provide habitat for greater than 80 percent of wildlife species. Wyoming is currently ranked sixth of the 50 states in the size of its breeding waterfowl population, and beaver ponds may play a significant role in providing habitat for these birds. The objectives of this research were to: (1) identify streams in Wyoming where beaver are currently present, extirpated, or used to manage riparian habitat; (2) identify areas where beaver could be relocated to create wetlands and improve riparian habitat; (3) compare wetland surface areas between areas that have beaver with those that did not; and (4) compare waterfowl numbers in areas with and without beaver. Using a survey of 125 land managers in Wyoming, we found that beaver have been removed from 23 percent (6,497 kin) of the streams for which managers had direct knowledge (28,297 kin). The same managers estimated that there are over 3,500 km of streams where beaver could improve habitat conditions. The riparian width in streams with beaver ponds averaged 33.9 m (95 percent CI = 25.1–42.7 m) in contrast to 10.5 m (CI = 8.6–12.4 m) in streams without beaver. During waterfowl surveys we counted 7.5 ducks/km (CI = O.9–14.4 ducks/kin) of stream in areas with beaver ponds and only O.1 ducks/km (no CIs calculated) of stream in similar areas without beaver present. Beginning in 1994, we restored beaver to 14 streams throughout Wyoming in an effort to create wetlands and improve riparian habitat. Waterfowl have been quick to respond to these important habitats. We feel that beaver restoration and management can be used to improve habitat in drainages where conflicts with other land uses are minimal.

“…The impact of this wetland loss on macroinvertebrate biodiversity is consequently unknown. Moreover, wetland invertebrates are also important food sources for fish and wading birds (Peterson & Low, 1977; Safran et al. , 1997), so activities that adversely affect invertebrate communities in New Zealand’s wetlands may also have wider effects on higher trophic levels.…”

1. Invertebrates were collected semi-quantitatively from four relatively undisturbed wetlands in the west coast of New Zealand's South Island: two acidic fens and two swamps. Samples were collected from up to four discrete habitats within each wetland: large open-water channels, small leads (small, ill-defined channels with emergent vegetation in them) and large (>10 m diameter) or small (<10 m diameter) ponds. Samples were also collected from different plant species within each wetland, each with different morphology, and from areas without vegetation. This was done to determine whether invertebrate communities varied more between-wetlands than within-wetlands, as the results had implications for future wetland monitoring programmes. 2. Principal components analysis of water chemistry data revealed striking differences in pH, conductivity and nutrients between the four wetlands. Not surprisingly, pH was lowest in one of the acidic fens, and highest in one of the swamps, where conductivity was also high. Midges (Tanytarsus, Tanypodinae, Orthocladiinae and Ceratopogonidae), nematodes, harpactacoid copepods and the damselfly Xanthocnemis dominated the invertebrate fauna. Orthoclad midges and mites were the most widespread taxa, found in 91 of 94 samples. Diptera were the most diverse invertebrate group, followed by Trichoptera and Crustacea. 3. Ordination analysis of the invertebrate data showed that the four wetlands supported different invertebrate communities. However, species composition did not change completely along the ordination axes, suggesting that a relatively species-poor invertebrate fauna was found in the wetlands. Taxa such as molluscs were restricted to wetlands with high pH. Multi-response permutation procedures (MRPP) was used to analyse resultant ordination scores to see how they differed according to five terms: 'Wetland', 'Habitat', 'Growth Form', 'Morphology' and 'Plant'. Most of the sample separation along ordination axes reflected differences between wetland, although the 'Habitat' and 'Plant' terms also explained some of the variation. The 'Growth Form' and 'Morphology' terms had only minor effects on community composition. 4. A multivariate regression tree modelled invertebrate assemblages according to the five predictor terms. The resultant model explained 54.8% of the species variance. The 'Wetland' term contributed most to the explanatory power, followed by 'Habitat'. 'Growth type' and 'Morphology' explained only a small amount of variance to the regression tree, while the different plant species explained none of the variation. 5. Variation in these New Zealand wetland invertebrate communities appears to be controlled most by large-scale factors operating at the level of individual wetlands, although different habitats within individual wetlands contributed slightly to this Correspondence: A. M. Suren, 727 variation. Based on these results, sampling programmes to describe wetland invertebrate communities do not need to sample specific habitats or plant types within a wetland. Instead,...
