Available in PDF, EPUB and Kindle. Book excerpt: Recent studies indicate waterfowl production per unit of water area on western rangelands exceeded that found on the prairie Pothole Region. However, production per km2 is far less on these western rangelands because of low pond numbers. This study was initiated to compare breeding populations and productivity between rangelands with relatively high and low numbers of stockponds. Breeding pair populations and waterfowl broods were assessed on 3 areas differing in pond densities in South Phillips County, Montana during 1990 and 1991. Pond physical parameters were measured and related to waterfowl production. Numbers of pairs, productivity, and numbers of young produced were positively correlated with pond density. Retention type ponds ranked highest in the above factors, due primarily to increased water area, shoreline length, and shoreline development indices associated with this pond type. Nest losses to predation were not significant. Other factors influencing waterfowl production i.

This book was released on 2011 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continental waterfowl population declines in the early 1980s led to the development and implementation of the North American Waterfowl Management Plan. The plan identified wetland and grassland losses in the Prairie Pothole Region (PPR) of Canada and the United States as the major causes of low continental duck populations. North-central Montana is the only remaining PPR area in the United States without a ground-based annual survey to monitor breeding duck populations and quantify breeding duck habitat. The purpose of this study was to establish an annual breeding duck survey in north-central Montana to 1) develop species-specific breeding pair predictive models, and 2) apply the models to estimate the density and distribution of breeding ducks and identify priority areas for conservation actions. 1969 indicated breeding duck pairs were observed on approximately 700 wetland basins in 2008 and 2009. A competing model analysis was used to identify local- and landscape-scale habitat characteristics to predict breeding duck pairs on wetland basins. The five most commonly observed species were modeled separately; those species were mallard (Anas platyrhynchos), northern pintails (A. acuta), gadwall (A. strepera), northern shoveler (A. clypeata) and blue-winged teal (A. discors). At the local scale, wetland basin area, the square root transformation of wetland basin area and wetland basin class were important predictors for all species. Northern pintail, gadwall and blue-winged teal exhibited a strong location effect, occurring more in the northern and eastern portions of the study area. At the landscape scale, the proportion of agricultural lands surrounding a sample basin was associated with the greater abundance of all species. Northern pintail and blue-winged teal breeding pair abundance increased when the proportion of seasonal and semipermanent basin wetland surface area in the landscape around sample basin decreased. Results from this study provide land managers with initial information on where breeding waterfowl are settling across the PPR landscape of north-central Montana. The continuation of this research for several more breeding seasons will enable conservation partners to efficiently target important breeding waterfowl habitat for conservation actions.

Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen a huge increase in the interest and attention directed toward sea ducks, the Mergini tribe. This has been inspired, in large part, by the conservation concerns associated with numerical declines in several sea duck species and populations, as well as a growing appreciation for their interesting ecological attributes.

Available in PDF, EPUB and Kindle. Book excerpt: The northern prairie region includes the prairie pothole region and the Nebraska sandhills. The first chapter deals with the social and economic conditions in the prairie pothole region and their impacts on the perception that farmers, business executive, and politicians in the region have of its wetland. The next three chapters deal with hydrology and water chemistry. They describe the physical and chemical environment of northern prairie wetlands. The flora and fauna are covered in seven chapters. An overview of the ecology of the wetlands of the Nebraska sandhills is provided in the last chapter.

This book was released on 2014-04-05 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.
