Conservation (W3)

The Conservation Alliance is a non-profit organization of outdoor businesses whose collective annual membership dues support grassroots citizen-action groups and their efforts to protect wild and natural areas.

Founded in 1990, "Raincoast Conservation Society" is a non-profit research and public education organization. We work in partnership with scientists, First Nations, local communities and Non-governmental Organizations to build support for decisions that protect marine and rainforest habitat on BC’s central and north coast.

Most Endangered Parks
This year the National Parks Conservation Association listed the following parks as the most endangered parks. I included the main reasons and they are linked to the National Park Service sites.

• "Big Thicket National Preserve" - a timber company is selling land that surrounds the park. If the new buyer decided to clear cut the land it could have adverse effect on the Big Thicket National Preserve.
• "Denali National Park and Preserve" - allowing motorized access into certain parts of the park that are closed to motorized access. This could affect the wildlife. Also potentially building a $200 million dollar road on the North side of the park could affect the caribou herds and wolves.
• "Everglades National Park" - which is one of the worlds largest fresh water marshes faces many problems including pollution, low water levels, and poor enforcement of regulations.
• "Glacier National Park" - our spectacular park in Montana along the Canadian border is facing threats from mining, more highways along the southern border, and potential pollution from oil and gas companies sites right outside the park.
• "Great Smoky Mountains National Park" - air pollution is a major problem here. This park has lots of acid rain, haze, and ozone. Not the kind of "Smoky" that we need in this park. Please tell the Tennessee Valley Authority to clean up it's power plants like it promised and then didn't.
• "Joshua Tree National Park" - development and a potential large land fill that is bordered by the park. This could cause air pollution, noise and light pollution.
• "Ocmulgee National Monument" - this national monument , near Macon, Georgia, has evidence of 12,000 years of human habitation in and around this site. Chronic underfunding and development around the site puts priceless artifacts at risk.
• "Shenandoah National Park" - air pollution has cut the views from the parkway from 100 miles to as little as one mile on some summer days. Also acid rain affects the trees and wildlife such as brook trout. Coal and oil burning power plants need to update their pollution control equipment.
• "Virgin Islands National Park" - potential development near the park could cause damage to coral reefs, mangrove shorelines and critical bird habitat. Also Government regulations need to be enforced including a no-take zone (no fishing zone) in and around the Virgin Islands Coral Reef National Monument.
• "Yellowstone National Park" - pollution due to snowmobiles in the winter (which have caused some park rangers use hearing protection and wear respirators while working around all the pollution and noise caused by the snowmobiles). Also there is a risk of potential large coal fired power plant near Yellowstone which could cause air pollution.

The National Parks Conservation Association was founded in 1919 to protect our National Parks.

Introduction to the National Museum of Natural History
The "National Museum of Natural History" ("NMNH") is part of the "Smithsonian Institution", the world’s preeminent museum and research complex. The Museum is dedicated to inspiring curiosity, discovery, and learning about the natural world through its unparalleled research, collections, exhibitions, and education outreach programs. Opened in 1910, the green-domed museum on the National Mall was among the first Smithsonian building constructed exclusively to house the national collections and research facilities.

The "Partnership for the National Trails System" ("PNTS") was established in 1995 to facilitate interaction and cooperation among the various private groups and goverment agencies involved with the national scenic and historic trails of the National Trails System.

The National Trails System is the network of scenic, historic, and recreation trails created by the National Trails System Act of 1968.

These trails provide for outdoor recreation needs, promote the enjoyment, appreciation, and preservation of open-air, outdoor areas and historic resources, and encourage public access and involvement.
