Lower Eel River and Van Duzen River Juvenile Coho Salmon (Oncorhynchus Kisutch) Spatial Structure Survey 2013-2016 Summary Report
Pacific States Marine Fisheries Commission in partnership with the State of California Department of Fish and Wildlife and Humboldt Redwood Company Summary Report to the California Department of Fish and Wildlife Fisheries Restoration Grant Program Grantee Agreement: P1210516 Lower Eel River and Van Duzen River Juvenile Coho Salmon (Oncorhynchus kisutch) Spatial Structure Survey 2013-2016 Summary Report Prepared by: David Lam and Sharon Powers December 2016 Abstract Monitoring of coho salmon population spatial structure was conducted, as a component of the California Department of Fish and Wildlife’s Coastal Salmonid Monitoring Program, in the lower Eel River and its tributaries, inclusive of the Van Duzen River, in 2013, 2014, 2015, and 2016. Potential coho salmon habitat within the lower Eel River and Van Duzen River study areas was segmented into a sample frame of 204 one-to-three kilometer stream survey reaches. Annually, a randomly selected subset of sample frame stream reaches was monitored by direct observation. Using mask and snorkel, surveyors conducted two independent pass dive observations to estimate fish species presence and numbers. A total of 211 surveys were conducted on 163 reaches, with 2,755 pools surveyed during the summers of 2013, 2014, 2015, and 2016. Coho salmon were observed in 13.5% of reaches and 7.5% of pools surveyed, and the percent of the study area occupied by coho salmon juveniles was estimated at 7% in 2013 and 2014, 3% in 2015, and 4% in 2016. i Table of Contents Abstract ......................................................................................................................................................... -

From Trinity Alps unusual red peaks to vast stands of virgin timber The Scott Mountains to jagged granite turrets, the Trinity Alps are at The Salmon Mountains once reminiscent of the more well known regions like the Sierra Nevada, yet are distinctly unique, Trinity Alps Regions with incomparable spectacles. Indeed, this is one Green Trinities of the great American wilderness regions. Few White Trinities places offer such limitless vistas, spectacular Red Trinities peaks, rugged landscapes, varieties of terrain Peaks and biodiversity and sense of vastness as the Trinities. Yet, despite the superlatives, the Trinity Lakes Alps receive relatively few visitors. It is not Waterfalls unusual to arrive at one of the more popular Trailheads destinations in the Trinities and find no one Trailhead Map present.

Vegetation Descriptions NORTH COAST and MONTANE ECOLOGICAL PROVINCE
Vegetation Descriptions NORTH COAST AND MONTANE ECOLOGICAL PROVINCE CALVEG ZONE 1 December 11, 2008 Note: There are three Sections in this zone: Northern California Coast (“Coast”), Northern California Coast Ranges (“Ranges”) and Klamath Mountains (“Mountains”), each with several to many subsections CONIFER FOREST / WOODLAND DF PACIFIC DOUGLAS-FIR ALLIANCE Douglas-fir (Pseudotsuga menziesii) is the dominant overstory conifer over a large area in the Mountains, Coast, and Ranges Sections. This alliance has been mapped at various densities in most subsections of this zone at elevations usually below 5600 feet (1708 m). Sugar Pine (Pinus lambertiana) is a common conifer associate in some areas. Tanoak (Lithocarpus densiflorus var. densiflorus) is the most common hardwood associate on mesic sites towards the west. Along western edges of the Mountains Section, a scattered overstory of Douglas-fir often exists over a continuous Tanoak understory with occasional Madrones (Arbutus menziesii). When Douglas-fir develops a closed-crown overstory, Tanoak may occur in its shrub form (Lithocarpus densiflorus var. echinoides). Canyon Live Oak (Quercus chrysolepis) becomes an important hardwood associate on steeper or drier slopes and those underlain by shallow soils. Black Oak (Q. kelloggii) may often associate with this conifer but usually is not abundant. In addition, any of the following tree species may be sparsely present in Douglas-fir stands: Redwood (Sequoia sempervirens), Ponderosa Pine (Ps ponderosa), Incense Cedar (Calocedrus decurrens), White Fir (Abies concolor), Oregon White Oak (Q garryana), Bigleaf Maple (Acer macrophyllum), California Bay (Umbellifera californica), and Tree Chinquapin (Chrysolepis chrysophylla). The shrub understory may also be quite diverse, including Huckleberry Oak (Q. -
Environmental Setting
Draft PEIR July 2010 8.5 FLOODING This section evaluates flooding impacts associated with the proposed General Plan, including whether implementing the plan will: (1) permit the construction of housing within a 100-year Flood Hazard Area; (2) allow structures within a 100-year Flood Hazard Area that impede or redirect flood flows; and (3) expose people or structures to a significant risk involving flooding as a result of levee failure or mudflows. Water quality and drainage impacts are evaluated in Sections 5.1 and 7.3, respectively. Environmental Setting Watersheds The Eel River has the largest watershed in Humboldt County. The river flows in a northwesterly direction, turning north as it passes Fortuna, then west at Fernbridge before reaching the Pacific Ocean north of Ferndale. The Fortuna Planning Area’s watersheds represent a small portion of the Eel River Watershed and either replenish local groundwater supplies or drain to the Eel and Van Duzen rivers and their tributary streams. The Rohner Creek and Strongs Creek watersheds are the largest in the Fortuna Planning Area. Smaller watersheds in the Planning Area include the Jameson Creek and Mill Creek watersheds; both tributary to Strongs Creek. The Hillside Creek watershed is a tributary of Rohner Creek and the North Fortuna drainage area discharges directly to the Eel River. North of the Fortuna city limits are the Palmer and Little Palmer Creek watersheds. Wolverton Gulch watershed lies to the south. Planning Area watersheds, rivers, and streams serve as natural resources, storm water drainages, and flood conveyance channels. Surface Water Flows Surface water flows have shaped the Planning Area topography. -
The Legacy of the Log Boom Humboldt County Logging from 1945 to 1955 Logging in Humboldt County in Northwestern California Began in 1850
Paul G. Wilson The Legacy of the Log Boom Humboldt County Logging from 1945 to 1955 Logging in Humboldt County in northwestern California began in 1850. When settlers first saw the giant old growth coast redwoods in Humboldt County they were in awe of them. These trees had diameters up to 30 feet and heights up to almost 400 feet. Old growth redwood trees are the oldest living things on earth; they can live about two thousand years. The settlers of Humboldt County had a respect for the redwoods; however, the settlers saw an immediate profit to be made. Old growth redwood lumber was used to build houses, railroad ties, shingle bolts, fence posts, and grape stakes.1 Redwood timberland in Humboldt County was located near the coast and extended twenty-five miles inland. The mills that cut the redwood logs into dimension sized lumber were located on the shores of Humbolt Bay. Humboldt Bay was a safe place for ocean vessels to pick up loads of redwood lumber to be sent to San Francisco Bay. Lumber vessels were often overloaded with redwood lumber. Because the vessels were piled with lumber, the vessels were believed to be unsinkable.2 Redwood lumber was sent all over the world for its preference in woodworking. In 1878 the United States government passed the Timber and Stone Act which allowed loggers to buy 160 acres of timberland for $2.50 per acre as long as the loggers "improved" the land through logging and ranching. Loggers acquired thousands of acres of redwood land and often formed partnerships to begin lumber companies.
