85 million acres of private land protected for conservation in the US and Australia

Australia and the United States are quietly protecting tens of millions of acres of private land for nature—often thanks to estates, philanthropy and creative partnerships. From family bequests that lock in habitats for the long term to nonprofit-led land purchases and leases, private conservation is expanding at a scale that rivals public reserves.

The movement is driven by a mix of donors, local land trusts and organizations that stitch together private parcels into functioning landscapes. Together, these efforts are reshaping how we conserve wildlife, safeguard water and reconnect people with wild places.

Private conservation surges in Australia: millions of acres protected

Australia has emerged as a global leader in private conservation, with nonprofit and private initiatives protecting millions of acres that fall outside formal national parks. A growing number of landowners are designating their properties for conservation through trusts, bequests and legal protections—creating a patchwork of privately managed reserves that complement government lands.

• 24 million acres now fall under private conservation arrangements across Australia.
• Organizations such as Bush Heritage Australia play a major role, managing roughly 3 million acres of that total.
• Local groups—including regional trusts in places like Tasmania—are also securing habitat on private holdings and pastoral country.

Bush Heritage and state recognition for privately held reserves

Bush Heritage has grown its footprint partly through donations left in wills and estate gifts, a trend that has accelerated in recent years. That support has allowed the charity to acquire and steward properties that protect species and ecosystems not covered by the national reserve system. In some cases, state governments have granted protections to privately conserved properties that are equivalent to national park status—an example of public endorsement of private action.

How bequests, trusts and legal tools make long-term protection possible

Many private conservation gains come from careful legal planning and community fundraising. Bequests—where land or money is left to conservation groups in wills—have been a powerful driver of new protected areas. Other tools include conservation covenants, land trusts and voluntary agreements that bind future owners to conservation objectives.

• Bequests provide both land and operational funding for ongoing stewardship.
• Conservation easements or covenants can prevent subdivision, clearing or mining even when ownership changes hands.
• Private reserves often protect culturally important landscapes as well as biodiversity hotspots.

These arrangements are particularly important because many of the continent’s most vulnerable habitats lie on private or pastoral lands and therefore are at risk from development pressures, extraction or invasive species.

In the U.S., private-public partnerships are stitching together big landscapes

Across the United States, private organizations are pooling land purchases, leases and donations to create large, connected conservation areas. One prominent example is American Prairie in Montana, which has spent decades assembling ranches and public leases to rebuild an expansive prairie ecosystem.

• American Prairie now manages about 603,657 acres, including 167,070 deeded acres and 436,587 leased public acres.
• The organization’s long-term ambition is to protect—or in places, rewild—around 2.3 million acres across a mosaic of grasslands, hills, wetlands and riparian corridors.
• Major milestones have included large land purchases that reopened access to public lands and the removal of hundreds of miles of obsolete fencing to restore wildlife movement.

Rising public interest and recreational use

Visitor numbers to American Prairie properties and facilities have climbed steadily, reflecting growing public appetite for outdoor experiences on protected private lands. In recent seasons the network reported record overnight stays in its huts and campgrounds, together with strong attendance at its discovery center—signs that private conservation can also expand access and engagement.

National picture: Land Trust Alliance and the scale of private reserves in the U.S.

A national nonprofit that supports land conservation reports that private efforts already account for a massive area: roughly 61 million acres in the United States are held specifically for conservation purposes. That amount exceeds the combined acreage of all U.S. national parks and represents a meaningful portion of privately owned land with conservation intent.

• Those 61 million acres include deeded nature preserves, conservation easements and land managed under nonprofit stewardship.
• Private conservation currently represents about 3% of the roughly 60% of U.S. land that is privately owned.
• The Land Trust Alliance has set an ambitious target to double that acreage by the end of the decade through expanded partnerships and funding.

Why private conservation matters—and the challenges ahead

Private reserves can protect habitats that formal national systems miss, connect fragmented landscapes, and provide flexible management approaches tailored to local needs. They also often mobilize private capital and volunteer energy, accelerating acquisitions and stewardship that governments may not be able to fund.

However, private conservation faces hurdles:

• Legal permanence: Ensuring protections survive changes in ownership requires clear covenants and durable governance.
• Funding: Long-term management, invasive species control, and fire management need steady revenue.
• Recognition and policy support: Aligning state and federal policies with private conservation goals can unlock stronger protections and incentives.

Public acknowledgment—from state-level park equivalencies to cooperative land-management agreements—can strengthen private efforts and expand their conservation impact. With coordinated strategies, private and public sectors together can protect extensive landscapes that support biodiversity, cultural values and outdoor recreation—without relying solely on traditional government-run parks.
