The Nature Conservancy is a not-for-profit agency dedicated to preserving the diversity of Earth's wildlife by saving some 120 million acres of land, 5,000 miles of rivers, and 100 marine areas in every US state and more than 30 countries worldwide. The organization originally carried out its mission by simply buying land, but it has evolved to incorporate other methods to further its goals. In addition to land acquisition, the organization partners with government, corporate, and private entities to reduce harmful use of natural areas, to create conservation-friendly public policy, and to increase conservation funding. The Nature Conservancy was founded in 1951 and uses about 80% of its funds on projects.

The Nature Conservancy (TNC) is the star performer among environmental groups, in size, growth, effectiveness, and stature among government agencies and private donors. On average, 1,000 acres a day are added to its system of nature preserves, the world's largest. When TNC cannot buy desired property, it sometimes attains conservation easements restricting use of the land in return for tax benefits.
TNC traditionally has maintained a low profile, preferring to let its partners reap the media attention. It began pressing, however, for more publicity in this earth-friendly age, garnering numerous product sponsorship deals as its membership approached one million. Author Peter Drucker singled out the management skills of the group, whose MBAs and lawyers injected a powerful dose of high finance into a field better known for grass roots activism.
The Ecological Society of America, a scientific group, was founded around 1900. In 1917 it formed a study group, the Committee for the Preservation of Natural Conditions, that would split from the Society in 1946 to become The Ecologist's Union.
One of this group's members, engineer Dick Pough, learned of the Nature Conservancy of the British government while traveling to England. In 1951 The Ecologist's Union adopted the name The Nature Conservancy, although Pough envisioned private rather than state support for the group. Donations from Pough's wealthy connections--such as $100,000 from Reader's Digest cofounder Mrs. DeWitt Wallace--put TNC in business.
TNC bought its first 60-acre property, Mianus Gorge, in 1955, sparing it from the development that surely would have spread from nearby New York City. Other small preserves followed, and the group found itself in competition with the venerable Audubon Society, also soliciting property donations.
This year marked the beginning of TNC's Land Preservation Fund, which acted as a rotating credit account. From an initial $7,500 donated by the Old Dominion Foundation the fund blossomed to more than $100 million by 1990. Mining heiress Katharine Ordway donated more than $53 million.
TNC bought the entire island of St. Vincent off of Florida's gulf coast for $1 million in 1969. It became a 13,000-acre national wildlife refuge. The 40,000-acre Virginia Coast Reserve was even more ambitious. The Virginia Coast Reserve was first begun in 1969 to protect nesting shore birds in particular from a developer who wanted to continue the development in overcrowded Virginia Beach to the barrier islands. After TNC began making acquisitions, however, politicians scrapped plans for bridges connecting the islands to the mainland.
By the 1970s the character of the organization had shifted from that of a scientist's group to something more akin to that of a property management company. TNC had about 50 employees, including Pat Noonan, a determined MBA who served as director of operations.
The group began to court corporations, the scourge of many environmentalists, for land donations. Union Camp Corporation donated 50,000 acres of the Dismal Swamp, a gift worth $12.6 million and believed to be the largest corporate donation at the time.
The Nature Conservancy employed a novel strategy in acquiring 35,000 acres of Mississippi swampland in 1973. When some of the shareholders of the Pascagoula Lumber Company vetoed a purchase offer of $15 million, it bought a controlling interest in the company. In 1976 TNC sold the land to the state of Mississippi for use as a state park. Mississippi, with its sportsmen-oriented approach to conservation, gave TNC a foothold in the Southeast.
In the case of Shelter Island, TNC bought all of a New York realty company's holdings, including property in Manhattan and Miami, to attain some Long Island osprey habitat. After the excess was resold, the land for Mashomack Preserve cost $5 million. Within 20 years, the osprey population had doubled.
Pat Noonan became president of TNC in 1974. At the insistence of its board of directors, TNC had developed a long-range plan. The United States was divided into regions, which would start the next level of organization: self-funding programs in each state.
Dr. Robert Jenkins, TNC's chief scientist, proposed a rescue mission for TNC: "The preservation of biotic diversity." He often alluded to Noah's Ark. TNC attempted to preserve specific species at risk by controlling specific habitats. The first of 50 State Natural Heritage Programs was established in South Carolina in 1974. After receiving initial support from TNC in identifying species at risk, the programs reverted to state funding.
An international program also was started. It eventually grew to include dozens of preserves in Latin America and the Caribbean, as well as projects centered in Canada, Palau, and Indonesia.
In 1978 TNC spent $2.8 million on its largest purchase at the time, buying nine-tenths of Santa Cruz, an isolated island off California whose rare native plant species had been severely threatened by feral pigs and 30,000 sheep, which TNC would have to eradicate. Fortunately, an ecologically savvy New England heiress supplied a quarter of the $4 million required to complete the project.
Pat Noonan stepped down as president in 1980 but continued to serve as a consultant, as TNC required all the creativity it could muster. During the Reagan years, money for public programs of all kinds was scarce and Secretary of the Interior James Watt halted federal land acquisition. Nevertheless, TNC was able to persuade the state of Mississippi to support the launch of the Rivers of the Deep South program, which began with a massive $15 million grant from a private foundation.
By 1984 TNC had invested $25 million in the Virginia Coast Reserve, now expanded to include deepwater frontage along the eastern shore of the Virginia mainland. Since TNC could not sell the land to the federal government as a wildlife refuge during the Reagan administration, it was financed by an innovative charitable lead trust, which allowed the tax-free distribution of a foundation's real estate investment.
In 1984 TNC turned over to the federal government the 118,000 acres of North Carolina coastland that would become the Alligator River National Wildlife Refuge. Red wolves would be first reintroduced into the wild here. The same year, the largest privately held preserve, the 67,000-acre Panther Ranch, was given to TNC by the Harte family of Texas. Most of it became part of the Big Bend National Park straddling the Rio Grande. The year 1984 also marked the establishment of Coachella Valley Preserve, which helped keep 13,000 acres of expensive Palm Springs real estate habitable for creatures like the fringe-toed lizard.
While other environmental groups such as Greenpeace (which eschews any corporate support) made headlines by chasing whaling ships and blocking logging roads, TNC's less confrontational approach attracted a broad base of supporters. By 1985 membership stood at 300,000.
TNC began a unique program, surveying 25 million acres of Department of Defense property, in 1988. Another new partner was Ducks Unlimited, which it joined in buying $3.5 million of California farmland to be reverted to waterfowl habitat.
TNC began an extensive survey of 14,000 North American plant species and added an even more impressive purchase than the Santa Cruz property: nearly all of the Animas Mountain range in New Mexico--321,703 acres of diverse wildlife habitat formerly owned by the Gray Land and Cattle Company. Negotiations for the acquisition had begun in 1982. The Big Bend development protected marshland on a similar scale in the eastern United States. Big Bend soon was resold to the state of Florida.
In 1989 The Nature Company, a Berkeley, California catalog merchandiser, entered a partnership with TNC whereby it processed new memberships and donated a portion of its product sales. Income at the time was $168 million and in 1990 membership reached 600,000 as the last of 50 state chapters was added. With assets worth $620 million, TNC managed 1.5 million of the more than 5.5 million acres it had protected.
TNC promoted the concept of "greenways"--linear belts of wilderness connecting wildlife sanctuaries. Its philosophy grew to rely less upon acquisitions, preferring to convince existing owners to take care not to harm wildlife by using pesticides, and so forth.
TNC sometimes appeared the bane of property developers, resentful at being told how to use their land and at the millions spent to preserve unappealing species such as crocodiles and rats. In addition, land acquired by the Conservancy no longer generated property taxes for local communities.
TNC also faced charges of threatening reluctant property owners. Further, an audit questioned prices federal agencies paid for TNC properties from 1986 to 1991. Subsequent reviews factoring in donations and other losses concluded, however, that TNC actually lost money on the deals.
Realizing the importance of accounting for people themselves in populated landscapes, TNC began acquiring new properties around its Virginia Coast Reserve to be resold with permanent restrictions to encourage certain uses, specifically, farming rather than coastal property development. TNC created the for-profit Virginia Eastern Shore Sustainable Development Corporation to manage the project, which included job creation among its objectives.
TNC extended its approach of compromise and cooperation to big business. Corporate giving accounted for $2 million, or 16 percent, of TNC income in 1991. By the mid-1990s, 500 companies, such as Miller Brewing Company, Canon USA, Honda of America, Procter & Gamble, and Warner-Lambert, supported TNC with donations, some of them through cause-related marketing. This arrangement allowed the corporate partners to use the TNC name and logo in promotions. TNC also introduced its own credit card.
In 1992 TNC helped broker a compromise between the Walt Disney Company, which wanted to expand its Orlando theme park, and the state of Florida, which wanted to protect adjacent wetlands. Disney agreed to restore 8,500 acres of wilderness in central Florida and was allowed to proceed with its development. TNC also worked out an agreement with Georgia-Pacific concerning timber harvesting on certain property. Each party held one vote to decide whether particular parts of the area should be harvested.
TNC reassessed its performance measures--such as acreage protected--after the bog turtle population in Schenob Brook, a Massachusetts acquisition, continued to decline because of uses of the watershed beyond the site's borders. The organization began seeking out much larger areas to preserve, designated Last Great Places, such as the Fish Creek Project organized to save a population of freshwater mussels. In this case, TNC helped subsidize no-till farming technology to reduce the amount of silt in the water. TNC's vision of preserving entire biological systems actually had been pronounced as far back as 1975.
To restore 36,000 acres of tallgrass prairie in Oklahoma bought in 1989, TNC initiated a series of prescribed burns there in 1993. A small herd of bison then was reintroduced onto the restored landscape. Membership reached 766,000 in 1993, revenues were $280 million, and nearly eight million acres had been protected. Assets approached $1 billion.
The number of species found in tropical rain forests ensured TNC's interest in foreign countries. A dozen Conservation Data Centers cataloged this ecological diversity around the globe, and its "Parks in Peril" program assisted national governments in maintaining existing parks. At the end of the century, TNC had operations in more than 20 countries. TNC helped preserve 57 million acres outside the United States, compared to ten million within. In 1996 TNC counted 900,000 members and 1,850 corporate associates.

The Nature Conservancy is a US charitable environmental organization working to preserve the plants, animals, and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive.[2]
Founded in 1951, The Nature Conservancy works in more than 30 countries, including all 50 United States, with an increasingly global reach. The Conservancy has over one million members, has protected more than 69,000 square kilometers (17 million acres) in the United States and more than 473,000 square kilometers (117 million acres[3]) internationally. The organization's total support and revenue was $1.28 billion in fiscal year 2007 with assets totaling $5.42 billion.[4]
The Nature Conservancy rated as one of the most trusted national organizations in Harris Interactive polls in 2007[5], 2006 [6], and 2005 poll[7]. Forbes magazine rated The Nature Conservancy's fundraising efficiency at 88% in its 2005 survey of the largest U.S. charities.[8] The Conservancy received a four-star rating from Charity Navigator in 2008[9] and was named by the organization in 2005 on their list of "10 of the Best Charities Everyone's Heard Of." The American Institute of Philanthropy gives the Conservancy an A- rating and includes it on its list of "Top-Rated Charities."
The Nature Conservancy is America's third-largest nonprofit by assets,[10] and America's largest environmental nonprofit by assets and by revenue.[11]
The Nature Conservancy is led by President and CEO Mark Tercek, a former managing director at Goldman Sachs, and an adjunct professor at New York University’s Stern School of Business.[12] The organization draws from all segments of the community. Retired General Norman Schwarzkopf, the Commander of coalition forces during the First Gulf War, was a member of the President's Conservation Counsel of the Conservancy. [13]

The Nature Conservancy takes a scientific approach to conservation, selecting the areas it seeks to preserve based on analysis of what is needed to ensure the preservation of the local plants, animals, and ecosystems. The Nature Conservancy is one of the world's largest environmental organizations as measured by number of members and area protected. It is a nonprofit organization supported primarily by private donations.
The Nature Conservancy works with all sectors of society including businesses, individuals, communities, partner organizations, and government agencies to achieve its goals. The Nature Conservancy is known for working effectively and collaboratively with traditional land owners such as farmers and ranchers, with whom it partners when such a partnership provides an opportunity to advance mutual goals. The Nature Conservancy is in the forefront of private conservation groups implementing prescribed fire to restore and maintain healthy ecosystems and working to address the threats to biodiversity posed by non-native and invasive plants and animals.
The Nature Conservancy has pioneered new land preservation techniques such as the conservation easement and debt for nature swaps. A conservation easement is a way for land owners to ensure that their land remains in its natural state while capitalizing on some of the land's potential development value. Debt for nature swaps are tools used to encourage natural area preservation in third world countries while assisting the country economically as well: in exchange for setting aside land, some of the country's foreign debt is forgiven.
The Nature Conservancy's expanding international conservation efforts include work in North America, Central America, and South America, Africa, the Pacific Rim, the Caribbean, and Asia. Increasingly, the Conservancy focuses on projects at significant scale, recognizing the threat habitat fragmentation brings to plants and animals. Below are a few examples of such work:
The Nature Conservancy was instrumental in the creation in 2004 of the Great Sand Dunes National Park in Colorado. The Conservancy's efforts in China's Yunnan province, one of the most vital centers of plant diversity in the northern temperate hemisphere, serve as a model for locally-based ecotourism with a global impact. The Nature Conservancy and its conservation partner, Pronatura Peninsula Yucatán, are working to halt deforestation on private lands in and around the 1.8 million acre (7,300 km²) Calakmul Biosphere Reserve, along the Mexico-Guatemala border. In November 2004, 370,000 acres (1,500 km²) of threated tropical forest in Calakmul were permanently protected under a historic land deal between the Mexican federal and state government, Pronatura Peninsula Yucatán, four local communities and the Conservancy.
The Nature Conservancy's programs in Idaho, Montana and Wyoming are working together to build partnerships and enhance the profile of the conservation needs in the Greater Yellowstone Ecosystem by supporting voluntary, private land conservation of important wildlife habitat. Conservation easements, land acquisition, stewardship agreements, grassbanks, prescribed fires and weed districts are a few of the tools the Conservancy and its partners use to protect this region's natural heritage. The Nature Conservancy's worldwide office is located in Arlington, Virginia.
The Conservancy was instrumental in the 2004 establishment of the Glacial Ridge National Wildlife Refuge in Minnesota. Glacial Ridge is reputed to be the largest tallgrass prairie and wetlands restoration project ever.
In 2007 the Nature Conservancy made a 161,000-acre (650 km2) purchase of New York forestland from Finch Paper Holdings LLC for $110 million, its largest purchase ever in that state.[15]
In 2008 June The Nature Conservancy and The Trust for Public Land announced they reached an agreement to purchase approximately 320,000 acres (1,300 km2) of western Montana forestland from Plum Creek Timber Company (NYSE:PCL) for $510 million. The purchase is part of an effort to keep these forests in productive timber management and protect the area’s clean water and abundant fish and wildlife habitat, while promoting continued public access to these lands for fishing, hiking, hunting and other recreational pursuits. [16]
The Nature Conservancy’s Plant a Billion Trees Campaign is an effort to restore 2,500,000 acres (10,100 km2) of land and plant 1 billion trees by 2015 in the Atlantic Forest of Brazil. Each donated dollar results in one planted tree in the Atlantic Forest. [5]
Environmental Benefits
The Plant a Billion Trees campaign has also been identified as a tool to help slow climate change, as the Atlantic Forest – one of the biggest tropical forests in the world – helps regulate the atmosphere and stabilize global climate. The reforestation of the Atlantic Forest has the capability to remove 10 million tons of carbon dioxide from the atmosphere every year. The Nature Conservancy states that this is equivalent to taking 2 million cars off the road. The Atlantic Forest’s restoration could help to slow the process of climate change that is affecting our planet.
The Nature Conservancy’s Plant a Billion Trees Campaign also aims to protect 10 critical watersheds in the Atlantic Forest that provide water and hydro power to more than 70 million people, create 20,000 direct jobs, and an additional 70,000 indirectly as part of this effort. The Plant a Billion Trees Campaign is also associated with The Nature Conservancy’s Adopt an Acre program, which consists of nine locations, including Brazil [6].
Involvement in the Community
Individuals who wish to participate in The Nature Conservancy’s Plant a Billion Trees Campaign can plant as little as one tree at a time (for a dollar each), can track the total count of trees planted using an online widget, can start their own tree planting campaign to raise money for plants through their own Web pages or social network profiles, or can sign up to give trees as a gift or make a monthly gift to plant trees each month at http://www.plantabillion.org.
The Nature Conservancy also features e-cards from the Atlantic Forest, as well as video of the Atlantic Forest and detailed information about the seedlings on their micro-site at http://www.plantabillion.org. The Web site also features a news feed and an interactive map of the Atlantic Forest region in Brazil, as well as information on many of the plants, animals, and people that are impacted by the plight of the forest and who may benefit from its restoration. [7]
Tree Planting
The Nature Conservancy plants one tree in the Atlantic Forest of Brazil for each dollar donated by supporters. The Conservancy makes every attempt to maintain the biodiversity of the existing forest in its restoration efforts.
Some of the seeds being planted consist of:
History of the Plant a Billion Trees Campaign
The Nature Conservancy launched the Plant a Billion Trees Campaign in 2008 with a micro-site (http://plantabillion.org) that is affiliated but not hosted by The Nature Conservancy’s Web site, http://www.nature.org.
As a part of this launch, The Nature Conservancy pledged to plant 25 million trees as part of the United Nations Environment Program (UNEP)’s Billion Tree Campaign.[17] This campaign encourages individuals and organizations to plant their own trees around the world and record this action on the website as a tally. The UNEP Billion tree Campaign is currently attempting to plant 7 billion trees by the end of 2009. [18]
On Earth Day 2009, Disneynature’s film “Earth” debuted, promising to plant a tree for every ticket sold to the film in its first week. This resulted in a donation of 2.7 million trees to the Plant a Billion Trees program. [19]
Partnerships
The Plant a Billion Trees Campaign has followed The Nature Conservancy’s approach of partnering with larger organizations (such as Disneynature, Planet Green, Penguin Books, Payless Shoesource, AT&T, Disney Worldwide Conservation Fund, and Visa) to leverage donations from supporters and increase efficiency and effectiveness of the campaign. [20]
The Nature Conservancy and its scientists also work with other conservation organizations, local landowners, state and federal officials, agencies, and private companies to protect, connect, and buffer what is left of the Atlantic Forest.[17]

Over the years, The Nature Conservancy has faced a number of criticisms. They fall into the following main categories:
| This section has been nominated to be checked for its neutrality. Discussion of this nomination can be found on the talk page. (September 2008) |
| “ | The Washington Post 'Big Green' series about The Nature Conservancy was based on a two-year investigation conducted by reporters from the Washington Post. The Nature Conservancy cooperated fully with the Washington Post, providing literally thousands of pages of requested documents and scheduling interviews with dozens of staff, partners and other experts, including four separate interviews with our president, Steve McCormick. Instead of a balanced report, however, the Washington Post 'Big Green' series lacked a fair contextual description of our accomplishments and simplified complex issues, explored in depth in the following pages.
Although the Washington Post 'Big Green' series was fraught with mischaracterizations and omissions of fact, we at The Nature Conservancy recognize some mistakes we have made in pursuit of innovation and conservation change. Many of these we had begun correcting and learning from before the Washington Post investigation began. We take full responsibility for our actions, as we always have. Through intensive self-examination across The Nature Conservancy, as we have done throughout our history, we know we will emerge a stronger organization, one better able to accomplish our conservation goals. |

The Nature Conservancy underwent investigation by the US Senate Finance Committee and passed.[27]
The Nature Conservancy has also been criticized, like many large environmental groups such as the Sierra Club and the World Wildlife Fund for using hunting in its management policies. Retired General Norman Schwarzkopf, the Commander of coalition forces during the First Gulf War, was a member of the President's Conservation Counsel of the Conservancy, is also a member of the trophy hunting organization the Safari Club [28]
From 2005-2007 the Nature Conservancy, along with the National Parks Service, enacted a policy of killing 4000 non-native feral pigs from the Channel Islands of California. The plan involved constructing six electric fences to enclose the island’s pig population. After the pigs were contained, they were shot by hunters in helicopters. The Nature Conservancy claimed that golden eagles had been drawn to the island by the pigs and were killing a native fox species. Channel Islands Animal Protection Association member Scarlet Newton argued: “The island fox population was robust until the Nature Conservancy took over the island....The finger goes right to the Nature Conservancy for causing the near extinction of the island fox.” She said that the Nature Conservancy chose to eradicate the non-native sheep populations of the island in the 1980s, the carcasses of which drew the golden eagles. [29] The Nature Conservancy used a human supremacist argument that the pigs were not natives of the island and thus had to be removed, which fails to acknowledge that ecological problems caused by non native human populations would be of equal or more immediate concern. David Theodoropoulos, author of Invasion Biology: Critique of a Pseudoscience, also said of the plan: " “No environmental problem exists which will require complete extermination." Peta had also criticized the Nature Conservancy of Hawaii in 1996 for using snares to control wild pigs. [30]
