Available in PDF, EPUB and Kindle. Book excerpt: "The Washington Department of Fish and Wildlife (WDFW) installed an eight-foot diameter rotary screw trap in the Nisqually River at river mile 12.8, near the Centralia City Light Yelm Hydro Powerhouse in 2009 to monitor outmigrating juvenile salmonids. The primary objectives of this study were to estimate abundance and document total catch, run timing, size and age composition of outmigrating juvenile Chinook salmon and steelhead. Our secondary objectives were to (a) estimate the abundance of juvenile Coho, Chum and Pink salmon; (b) document total catch, run timing, size and age composition of outmigrating of juvenile Coho, Chum, and Pink salmon; and (c) document species and total catch of non-target fish captured in the trap. Information collected at the Nisqually River rotary screw trap monitoring project provides critical abundance and life history information for the salmon and steelhead stocks within the river. These data coupled with adult return data can be used to measure key survival and productivity metrics to assess management practices and evaluate recovery efforts. This report describes the results of the monitoring efforts during the 2009-2015 field seasons."--From abstract.

This book was released on 2009 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The decline of many Pacific salmon stocks has stimulated interest in the early life history and habitat requirements of juvenile salmon. Although estuarine habitat associations of juvenile salmon have been investigated in many coastal areas of the eastern Pacific Ocean, until recently, little was known about juvenile salmonid ecology within the Straits of Juan de Fuca. During the Spring/Summer outmigration period in 2006 and 2007, I examined the early life history of the five species of anadromous salmon in the Dungeness River estuary on the north Olympic Peninsula, Washington. I sampled multiple spatial scales within several habitat types to characterize salmon distribution and habitat use. My results presented in this thesis are segregated into two components: 1) tidal marsh ecology of juvenile salmonids in the Dungeness River estuary, and 2) the landscape-scale distribution of juvenile salmonids within the Dungeness River estuary. I examined the population of juvenile salmonids within blind tidal sloughs near the vicinity of the Dungeness River delta. Salmonids were present within the tidal marshes throughout the entire outmigration period (e.g., March through July). Juvenile Chinook salmon (Oncorhynchus tshawytscha) were the most abundant salmonid species within the marshes. Based on the temporal distribution and size structure of juvenile Chinook salmon in the estuary I identified at least four life history types: 1) a fry strategy included a large pulse of fish emigrating from the river at a small size (e.g., 35-45mm FL) during late winter and early spring months; 2) the second group of fish was the least abundant group emigrating from the river from April through mid May at sizes ranging from 50-75mm FL; 3) the third group of migrants entered the estuary between from late spring through the summer months at larger sizes than the initial groups (e.g., 60-90mm FL); and 4) the final group of Chinook salmon included a stream-type yearling strategy. In addition to the four life history strategies identified for Chinook salmon, I detected at least three groups of chum salmon migrating into the estuary. These groups were distinguished by their size and timing of migration and are further described according to different rearing strategies. The distribution of juvenile salmonids was most strongly influenced by the degree of connectivity (i.e., distance) between the tidal marshes and the mouth of the Dungeness River. Habitat complexity and opportunity also governed the distribution of juvenile salmonids within the tidal marshes. I also sampled three regions of the estuary with a beach seine to investigate the nearshore distribution of juvenile salmonids within the Dungeness River estuary: the delta face, inner Bay, and outer Bay. Among the three regions, species composition was highly variable between 2006 and 2007. The most common salmonids encountered within the beach seine sites included Chinook salmon, chum salmon (O. kisutch), and pink salmon (O. gorbuscha). The relative abundance of salmonids was highest near the delta face and lowest within the outer bay area. The landscape-scale distribution and habitat use of juvenile salmonids within the Dungeness River estuary is largely influenced by ecosystem connectivity, but is also linked to biotic characteristics of the fish (e.g., life history type and fish size). Although the Dungeness includes hydrogeomorphic characteristics (e.g., steep river gradient, composition of sand spits in the estuary) unique to other Pacific Northwest watersheds, this system produces a variety of life history types comparable to other estuaries. Understanding the mechanisms that drive the distribution of juvenile salmonids within the Dungeness will supply local resource managers with a baseline with which to establish ecosystem restoration goals.

Book excerpt: Twenty-one writers answer the call for literature that addresses who we are by understanding where we are--where, for each of them, being in some way part of academia. In personal essays, they imaginatively delineate and engage the diverse, occasionally unexpected play of place in shaping them, writers and teachers in varied environments, with unique experiences and distinctive world views, and reconfiguring for them conjunctions of identity and setting, here, there, everywhere, and in between.

Available in PDF, EPUB and Kindle. Book excerpt: Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).
