Download or read book Aquatic Macroinvertebrate and Physical Habitat Monitoring for Coyote Gulch and the Escalante River in Glen Canyon National Recreation Area written by National Park Service and published by CreateSpace. This book was released on 2013-09-13 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Park Service (NPS) Inventory and Monitoring Program was designed to determine the current status and monitor long-term trends in the condition of park natural resources, providing park managers with a strong scientific foundation for making decisions and working with other agencies and the public to protect park ecosystems. The Southern Colorado Plateau Network (SCPN) is monitoring aquatic macroinvertebrates as an overall indicator of aquatic ecosystem integrity (Thomas et al. 2006). Coyote Gulch was sampled in 2005 and 2006 to develop and test the Aquatic Macroinvertebrate Monitoring Protocol for the Southern Colorado Plateau Network (Brasher et al. 2011). Previously, aquatic macroinvertebrates were sampled from the Escalante River and its tributaries by Vinson (2000, 2001, and 2002), Mueller (1999), and sporadically by others. Few data exist describing the aquatic ecology of these two streams in Glen Canyon National Recreation Area (GLCA).

This book was released on 2008 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spring ecosystems in arid regions are oftentimes the only permanent water source in the uplands and provide essential habitat for a myriad of aquatic and terrestrial organisms (Erman 2002); they are essentially aquatic islands in a sea of desert (Thompson et al 2002) . Riparian areas adjacent to springs can provide habitat to up to 75% of the available species diversity in arid regions (Shepard 1993). Spring ecosystems have evolved within a narrow set of environmental conditions strictly dependent on groundwater discharge (Shepard 19 93). Discharge of springs within Bighorn Canyon National Recreation Area (BICA) has been found to be dependent on snowmelt-based groundwater reaching outflows as recently as weeks after melting, to as long as years after (D. Schmitz, pers. comm.). The mosaic of microhabitats in springs is largely due to stable, long-term flow rates (Perla & Stevens 2003), and perennial discharg e has been linked to diverse, unique and often endemic flora and fauna (Myers 1995, Sada and Vinyard 2002). Aquatic macroinvertebrates can make up a substantial proportion of spring biodiversity. Aquatic species in spring ecosystems can display a high degree of endemism, often evolving to subtle cues in water chemistry (Arsufi 1993, Heino et al. 2003; Sada et al . 2005). Macroinvertebrate populations in springs of the Great Basin, Sierra Nevada, and Colorado Plat eau are known to support endemic aquatic macroinvertebrates (Erman 2002; Hershler and Sa da 2002; Sada and Herbst 2001). An initial survey of Great Basin Springs reported four new species of aquatic invertebrates (Myers 1995). A new species of the springsnail, Pyrgalopsis (the only species reported east of the continental divide) has recently been found in a Missouri River (Montana) spring (Hershler and Gustafson 2002). Even though most spring locations in BICA have been documented on USGS topographic maps, there has been no documentation of aquatic fauna occurring within these ecosystems. Spring flora and fauna in BICA have only been investigated for occurrence of rare riparian and wetland plants (ex.Sullivantia hapemanii var. hapemanii) (Heidel and Fertig 2000). Therefore, a survey of spring fauna will substantially increase the known BICA species and document potentially rare, endemic or endangered species. Surveys in this area will fill data gaps, serve as a reference point for change detection, provide a baseline necessary for evaluating the rarity of different spring ecosystem types, and form an understanding o biological diversity and integrity at the local and ecoregional level. Many spring species have narrow environmental ranges (specialists) and therefore are susceptible to changes in water chemistry and habitat quality Our main objectives for this study include 1) an initial aquatic invertebrate faunal survey and bioassessment of targeted perennial BICA springs, 2) determining the environmental factors that determine biointegprovide a sampling scheme and identify indicator measures (species richness, abundance, target species (i.e. endemics, etc.) with which to monitor spring diversity and biointegrity in the future. Achieving our objectives, especially the third, will allow park managers to monitor the status and changes of aquatic macroinvertebrate indicators over time within BICA springs. This process can be repeated every five years for any proposed spring-type monitoring protocol: an impaired (cattle or human impacted) sample and a reference (pristine) condition sample from each spring type
Download or read book Changes in the Land written by William Cronon and published by Hill and Wang. This book was released on 2011-04-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book that launched environmental history, William Cronon's Changes in the Land, now revised and updated. Winner of the Francis Parkman Prize In this landmark work of environmental history, William Cronon offers an original and profound explanation of the effects European colonists' sense of property and their pursuit of capitalism had upon the ecosystems of New England. Reissued here with an updated afterword by the author and a new preface by the distinguished colonialist John Demos, Changes in the Land, provides a brilliant inter-disciplinary interpretation of how land and people influence one another. With its chilling closing line, "The people of plenty were a people of waste," Cronon's enduring and thought-provoking book is ethno-ecological history at its best.
