This book was released on 2018 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intermittent streams are low-order creeks that experience seasonal reductions in flow; upon flow reduction, pools of water are separated by dry stream bed. These residual pools are important habitat during dry months for the aquatic organisms living the watershed. The Salmon Creek Watershed is located in central coastal California and creek flow becomes intermittent over the summer months; Endangered Species Act listed species Coho salmon (Oncorhynchus kisutch) and Steelhead trout (Oncorhynchus mykiss) spawn and rear in the watershed. This study contains to two reports that examined juvenile salmonid habitat over the course of a 5-year drought that occurred in this region. The first report- Assessing late-summer juvenile salmonid abundance- A report for the Gold Ridge Resource Conservation District- used Poisson regressions to determine which variables – dissolved oxygen, temperature, surface area, maximum depth, and three variations on cover- were most important for late-summer juvenile salmonid abundance. Surface area and depth were most important for both steelhead trout and coho salmon abundance, supporting previous research. Management efforts should focus on lower creek reaches to support habitat during low flow periods and habitat connection to upper reaches. The second report- A GIS story of Salmon Creek- visualized and assessed the Salmon Creek Watershed Council’s data archive. Surveying has been ongoing since 2013; and this report looked at years 2013,2015,2016, and 2017. From the data, three different map types: time-series maps, ecological observation maps and watershed wide views. I identified that three of the consistently surveyed creeks- Nolan, Fay and Tannery- showed reductions in dry lengths from 2015 to 2017. The ecological observation maps were designed as community outreach tools to garner community interest and support in protecting critical habitat for the salmonids. The Watershed Council’s continuous survey of the creeks provides valuable information for management

Download or read book Sediment Yield in Salmon Creek After Decommissioning Logging Roads Northern Humboldt County California written by Malia S.B. Gonzales and published by . This book was released on 2020 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmon Creek watershed is located in the Headwaters Forest Reserve in northern California and is known for the ecological value of its old-growth redwood forest, high biodiversity, and sensitive habitat for endangered species. The Bureau of Land Management primarily manages the Reserve. The land-use history of the Upper Salmon Creek watershed includes extensive timber harvest and road development. Watershed restoration in the Upper Salmon Creek watershed started in 2000 with the primary goal for the Reserve to protect and recover ecologic diversity and threatened native species. Since then, of the 23 miles, 13.5 miles of logging roads and 101 stream crossings have been decommissioned and treated, with 2 miles maintained, 2.4 miles passively restored, and 5.1 miles still requiring assessment. The restoration work is focused on long term reduction in sediment delivery from erosional sites that have historically degraded water quality in the Salmon Creek watershed. A stream monitoring station is located in the Upper Salmon Creek watershed that uses a turbidity threshold sampling protocol based on turbidity, stage, and temperature. The objective is to evaluate the data collected from Water Year (WY) 2012 to 2019 to assess the sediment yield in the watershed. The field and laboratory data collected at the stream monitoring station were used to further understand the relationships between hydrology, sediment transport, and land-use, and to estimate sediment load from WY 2012 to 2019. Additionally, two precipitation-monitoring stations were installed in the Upper Salmon Creek watershed during WY 2019, to provide a more spatially representative rainfall data set.

Download or read book California s Salmon and Steelhead written by Alan Lufkin and published by Univ of California Press. This book was released on 2022-08-19 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions upon millions of salmon and steelhead once filled California streams, providing a plentiful and sustainable food resource for the original peoples of the region. But over the years, dams and irrigation diversions have reduced natural spawning habitat from an estimated 6,000 miles to fewer than 300. River pollution has also hit hard at fish populations, which within recent decades have diminished by 80 percent. One species, the San Joaquin River spring chinook, became extinct soon after World War II. Other species are nearly extinct. This volume documents the reasons for the decline; it also offers practical suggestions about how the decline might be reversed. The California salmon story is presented here in human perspective: its broad historical, economic, cultural, and political facets, as well as the biological, are all treated. No comparable work has ever been published, although some of the material has been available for half a century. In the richly varied contributions in this volume, the reader meets Indians whose history is tied to the history of the salmon and steelhead upon which they depend; commercial trollers who see their livelihood and unique lifestyle vanishing; biologists and fishery managers alarmed at the loss of river water habitable by fish and at the effects of hatcheries on native gene pools. Women who fish, conservation-minded citizens, foresters, economists, outdoor writers, engineers, politicians, city youth restoring streambeds—all are represented. Their lives—and the lives of all Californians—are affected in myriad ways by the fate of California's salmon and steelhead.

Download or read book Using Landsat and a Bayesian Hard Classifier to Study Forest Change in the Salmon Creek Watershed Area from 19722013 written by David Stone Mullis and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Salmon Creek Watershed in Sonoma County, California, USA, is home to a variety of wildlife, and many of its residents are mindful of their place in its ecology. In the past half century, several of its native and rare species have become threatened, endangered, or extinct, most notably the once common Coho salmon and Chinook salmon. The cause of this decline is believed to be a combination of global climate change, local land use, and land cover change. More specifically, the clearing of forested land to create vineyards, as well as other agricultural and residential uses, has led to a decline in biodiversity and habitat structure. I studied subscenes of Landsat data from 1972 to 2013 for the Salmon Creek Watershed area to estimate forest cover over this period. I used a maximum likelihood hard classifier to determine forest area, a Mahalanobis distance soft classifier to show the softwares uncertainty in classification, and manually digitized forest cover to test and compare results for the 2013 30 m image. Because the earliest images were lower spatial resolution, I also tested the effects of resolution on these statistics. The images before 1985 are at 60 m spatial resolution while the later images are at 30 m resolution. Each image was processed individually and the training data were based on knowledge of the area and a mosaic of aerial photography. Each subscene was classified into five categories: water, forest, pasture, vineyard/orchard, and developed/barren. The research shows a decline in forest area from 1972 to around the mid1990s, then an increase in forest area from the mid1990s to present. The forest statistics can be helpful for conservation and restoration purposes, while the study on resolution can be helpful for landscape analysis on many levels.

Book excerpt: Along California's North Coast, where salmon hover on the cusp of extinction, scientists and local residents seek new collaborations. Agencies, tribes, and watershed councils commission competing studies to determine links between human water use, oceanic cycles, and salmon decline. Modelers turn to ranchers' expert opinions to condition hydrologic models. Ranchers import beavers to build dams that may raise the water table. These watershed collaborations begin to transcend boundaries of human institutions, scientist / lay person, and even species. Restoring salmon-bearing streams is a project to reconfigure human relationships to water and inhabitation practices. In infrastructures. the western U.S., this project necessarily entails a serious grappling with Manifest Destiny legacies of Native American sovereignty, property regimes, legal doctrines, and water My dissertation investigates how watershed collaborations transform scientific practices, environmental subjectivities, and trans-species relations, using Salmon Creek (Sonoma Co., CA) as a case. Salmon Creek is typical of thousands of small watersheds in the Pacific West in that summer water extractions by farmers and rural residents dry many tributaries into a series of disconnected pools. This anthropogenic drought compounds historic beaver removal, logging, and road building that have altered water, sediment, and large wood supply to the stream, limiting steelhead (Oncorhynchus mykiss) and coho salmon (O. kisutch) recovery. I argue that collaborative watershed research that refuses to privilege expert science over local and Indigenous knowledges can create novel modes of scientific practice, discursive shifts, and new governance approaches. I stretch the limits of the terms 'watershed' and 'collaboration' to encompass interactions among (1) scientists and local knowledge holders, (2) living species and the landscapes they inhabit, and (3) humans and other species that depend on riverine ecosystems. Though disparate in methodology, the fields --Science and Technology Studies, Environmental Politics, and Eco- hydrology--share a commitment to critically re-working social-natural boundaries. Natural flow regimes--dynamic streamflow patterns that drive riverine biodiversity--arise from a kind of collaboration between climatic factors, geology, plants, and animals in a river basin, and are then further shaped by human ground and surface water diversions. Regarding the ecosystem as a collaboratory in which humans play a role, Quantifying abiotic habitat characteristics to determine thresholds for salmonid oversummer survival in intermittent streams investigates the role of different flow-mediated factors (dissolved oxygen, temperature, groundwater inflow, and pool volume) affect juvenile coho and steelhead occurrence in two Salmon Creek tributaries. Drawing on three years of juvenile fish surveys, synoptic water and isotope monitoring and streamflow gauging to populate statistical models, I found that low dissolved oxygen and pool volume limit survival; however both salmonid species can survive in spring-fed intermittent pools that contain sheltering logs or overhanging banks. Citizen science surveys of stream drying patterns and salmon occurrence can complement agency monitoring and should be incorporated into salmon recovery efforts. Regarding human collaboratives of knowledge and practice, 'Thinking with salmon about rain tanks: stream commons as intra-actions' puts forth the argument that cultural practices of water use evolve in response to new understandings of other species' dependence on shared streams. Some Salmon Creek residents who install rain cisterns to curtail summer water use do so out of concern for salmon, and describe salmon and other riverine creatures as having rights to enough water to survive that are of the same status as human rights to water. Other residents are unwilling to reduce water use because the connection between their wells and the stream are poorly understood and difficult to measure. dissertation contributes to this 'Rain tanks, springs, and broken pipes as emerging water commons along Salmon Creek, CA, USA' . Residents who participate in monitoring salmon populations, water quality, and their own springs and rain tanks report that these activities have increased their sense of interdependence with other human and nonhuman neighbors who rely on the watershed's limited water sources. Drawing on Barad's (2007) concepts of apparatus and intra-action, I argue that the notion of water as an interspecies commons is co- evolving with rainwater harvesting and that collective choice frameworks that embrace both management practices and environmental imaginaries represent a coherent alternative both to state and market frameworks of water governance and to traditional adaptive management methods and discourses. foment discourses that bring humans and other species -- especially beaver and salmon, which affect water and nutrient cycles and thus are considered "ecosystem engineers"-- into symbiotic relations with mutual responsibilities. In the conclusion, I explore how these practices and local knowledge of springs, aquifers, and rainfall develops a method for studying up from household water Mobilizing approaches from feminist Science and Technology Studies, the introduction extends the idea of watershed collaborations to encompass humans and other species. I draw on extended interviews with scientists, policy-makers, and local residents to argue that members of knowledge practice collaboratives concepts of multi-species collaboratives may filter up from local collaborations into public water and species recovery debates, and consider limitations to more entangled approaches to watershed governance. Salmon Creek is geographically small and removed from major river basins, yet functions as a kind of microcosm of the political, cultural, and ecological tempests these salmon recovery and ecological restoration projects stir up at any scale. Salmon are simultaneously a global fishery resource, a key subsistence and cultural resource for traditional peoples around the Pacific, a scientific project to avert extinction, and a contested site of knowledge production. In asking what forms of collaboration are productive, and how collaborations transform those who undertake them, this research contributes to debates on practice and ethics inherent in environmental governance in the Anthropocene era.
