The Tualitin basin is more than fifteen miles wide in places and has many layers of Pliestoscene rock, sand, and gravel deposited by the hundred or so Lake Missoula Floods that washed down the Columbia Gorge. The Coast Range includes the highest density of streams found in the state, and deciduous riparian vegetation is distinct from surrounding coniferous forests. Where needed, direct activities to particular seasons or away from sensitive areas. The map below shows the location of each geological site we examined. The surrounding forest are primarily private owned and are actively managed for wood production.This COA stretches many miles from tidally influenced to the Willamette Valley and represents may strategy habitats.A rather small bay for the size of the river the COA is low elevation and low gradient with many islands and salt/freshwater marshesThis area contains much of the Coast Range’s Oak Woodlands and is potential habitat for Western Snowy Plover. Most of the ecoregion is dominated by coniferous forests. People are increasingly moving to the coast to retire, so retirement services are growing in importance to coastal communities.Timber, agriculture, commercial fishing, fish processing, tourism and recreation, and retirement servicesCoos Bay; Tillamook Bay; Oregon sand dunes; Siuslaw and Siskiyou National Forests; Clatsop, Elliot, and Tillamook State Forests; Oregon Dunes National Recreation Area; numerous state parks and waysidesAlsea, Chetco, Coos, Coquille, Illinois, Lewis and Clark, Necanicum, Nehalem, Nestucca, Rogue, Siletz, Siuslaw, Trask, Umpqua, Wilson, Yaquina, YoungsDemand for waterfront property is increasing, along with numbers of people recreating, relocating, and retiring along the Oregon coast. Along the coastal strip, habitats are influenced by the marine environment and include beaches, estuaries, and headlands.Some towns in Oregon’s Coast Range ecoregion include: Tillamook, Yachats, Astoria, Bandon, Cannon Beach, Elkton, Florence, Gold Beach, Lincoln City, Newport, and Waldport. Tidal flux can spread oil or other hazardous materials around sensitive habitats very quickly. The area includes coastal Sitka spruce forest, eventually opening up to a grassy bluff. Sea stacks punctuate the long sweep of shoreline to the south. MacLeod, Michael M. Kelly, Michael J. Parker, Johanna S. Fenton, and Tracey J. Felger 1995 The Oregon coast is made of a mixture of volcanic and sedimentary rocks. These hills are made up of a mixture of basalts, conglomerations, and their resulting weathered clays. It is a key corridor for migrating birds and has high plant and animal diversity.Relatively large (222 sq mi) area located within the Coast Range near the Rogue River-Siskiyou Forest and immediately adjacent to the Sixes River-Elk River COASea Level coastal lakes with limited tidal influence and large enough to have cold water and wavesTwo large coastal lakes with floating peat islands and large numbers of wintering waterfowl exist in this COA. The ecoregion’s mild, moist climate creates conditions for highly productive temperate rainforests, which are important ecologically and for local economies. The area includes Nehalem Bay State Park. Though the sun shone brightly, it was a cool and breezy Saturday morning when we gathered at the Portland Community College parking lot for the Spring Term Geology … The Oregon coast also enjoys some of the highest expenditures on wildlife viewing of anywhere in the state ($159 million in 2008When implemented carefully, with properly managed harvest levels and low-impact viewing practices, ecotourism is allowing local communities to capitalize on their natural resources in a sustainable way. For example, the Tillamook Burn, which is actually a series of wildfires that occurred from 1939-1951, burned approximately 350,000 acres. In the cuts here along Highway 26 we can see the basalts are formed in columnar jointing and were not formed under water. However, increasing numbers of recreationists can impact sensitive areas, such as shorebird nesting areas and tidepool habitats. Area is conterminal with Nestucca Bay and Trask Mountain COA.This area is conterminal with Sand Lake, Tillamook Bay COAs. Click on a site number and take the virtual field trip. The Oregon Coast Range is divided into three separate sections: North, Central, and South. These recreational opportunities, and the hospitality jobs they support, depend on healthy wildlife populations and habitats, which Oregonians can maintain and restore by working together. The area contains managed forest including components of mature stands and remnant large trees and open upland grassland meadows.This is a an extensive area on the lower Columbia River Estuary from east of Tongue Point upstream to Crims Island. The watershed provides critical habitat for many coastal plant and animal communities.
