The 5,200 hectare Forest Park provides an important refuge for hundreds of native plant and wildlife species and acts as an important air and water filter. Forest Park is a public urban park in the Tualatin Mountains west of downtown Portland, Oregon, USA. The park, a vital part of a local park and path system, encompasses more than 5,100 acres (2,065 hectares), mostly second-growth forest with some patch of old vegetation. roughly 110 km of fun trails, counting the Wildwood Trail division of the city’s 40-mile round system that runs during the park.
Before the 1860s, civic best tried to generate a nature preserve in the woods near Portland. His efforts led to the establishment of a municipal park commission, which in 1903 hired the landscape architecture firm Olmsted Brothers to develop a plan for Portland’s parks. The city acquired land through donations, Multnomah County transfers, and criminal tax foreclosures, eventually acting on a suggestion from the City Club of Portland, and combined parcels totaling approximately 4,000 acres (1,600 hectares) to create the reservation. It ranks 19th among parks in U cities, according to The Trust for Public Land.
More than 112 species of birds and 62 species of mammals inhabit the park and its large variety of shade-loving trees and plants. About 40 inches (1000 mm) of rain falls on the forest each year. some of the Willamette River’s little tributary flow northeast through the woods to pipes or culverts below U. Route 30 on the edge of the park. One, Balch Creek, has a resident trout population and another, Miller Creek, is home to marine fish species, including salmon. Solidified magma from the Grande Ronde members of the Columbia River basalt group underlies the Forest Park. The Willamette Valley. These currents, some of which reached the Pacific Ocean, were repeated at intervals between 16.5 and 15 minutes.6 million years ago and covered nearly 60,000 square miles (160,000 km2) about eight separate Grande Ronde basalt rivers have been mapped in the Tualatin Mountains (West Hills), here they lie beneath the steeper slopes of Forest Park and form the visible columnar rocks next to Balch Creek Canyon and Northwest Cornell Road. The western hills were later enclosed by wind-deposited sediments that become uneven when flooded with water. Riverbank instability and sedimentation are common, and landslides hinder urban development at higher elevations. Approximately eight miles long, the park is less than one mile wide near downtown Portland and about two miles wide on its northwest corner along the West Hills of West Burnside Street near downtown Portland Where the Willamette River divides and flows around Sauvie Island, it covers most of the east side of the ridge over the Willamette River and is bounded by West Burnside Street to the south, Northwest Skyline Boulevard to the west, and Northwest Newberry Road to the north and Northwest St. Helens Road (U.Route 30) in the East.
