Conservation covenants on private land
Landholders voluntarily register a binding agreement on their land title to protect native habitat, often permanently, sometimes with annual stewardship payments.
Start small
One landholder with koala habitat asks the state covenanting body (NSW BCT, Trust for Nature, or Queensland's private protected areas program) for a free site assessment, about 1 to 2 hours on site. Map koala food trees and corridor links on the property with a local Landcare group over a weekend, then apply to the next koala conservation tender. First-year cost to the landholder is close to zero apart from time; registration costs are often covered.
The problem
Loss of native koala habitat. Most remaining koala habitat in eastern Australia is on private land, where clearing and fragmentation are the main threats.
Where it fits
Needs law that lets a covenant stay with the title when land is sold (NSW Biodiversity Conservation Act 2016, Victoria's Trust for Nature Act, Queensland's Nature Conservation Act, US easement law), a trusted body to hold it, and money. Payments matter: the NSW Biodiversity Conservation Trust pays annual stewardship (median $163 per ha per year in the Northern Inland koala tender) through targeted tenders, while Victorian covenants are mostly unpaid. Uptake is strongest among conservation-minded landholders and where farm tax relief applies.
The principle underneath
Putting conservation on the land title separates who owns land from what can happen to it, so protection outlasts any one owner and costs far less than buying the land. Paying for ongoing stewardship turns habitat from a cost into an income, which draws in working farms and not just enthusiasts.
Who to call
NSW Biodiversity Conservation Trust (koala conservation tenders); Trust for Nature (Victoria); Queensland Private Protected Area Program and NatureAssist; Land Trust Alliance (US); Bush Heritage Australia; Australian Land Conservation Alliance; local Landcare and koala groups.
Watch out for
Unpaid covenants leave owners without money for weeds, fire and fencing. Mining and infrastructure can override covenants. Weak monitoring after sale to owners who do not share the values. Disputes are expensive to enforce. Covenants protect patches but do not stop clearing next door. Without targeted tenders, sites end up scattered and unconnected for koalas. Poorly designed tax incentives invite abuse.
Where it comes from
Grew from Anglo-American property law: US conservation easements and land trusts, Victoria's Trust for Nature (1972), and later NSW, Queensland and Tasmanian programs. NSW's BCT (2017) added paid in-perpetuity agreements allocated by tender. Open for use; on Aboriginal Country, involve Traditional Owners in planning and management.
Where it's worked
Georgia Basin, British Columbia, Canada · 100-year model, published 2015
Easements cost about 65% less than buying land and are about three times more cost-effective, provided disputes and violations stay rare.
Peer reviewedSource
United States (land trusts) · To December 2020
About 61 million acres voluntarily conserved through land purchase and conservation easements, up more than 15 million acres since 2010.
DocumentedSource
Queensland, Australia (Nature Refuges) · To June 2020
Voluntary nature refuge agreements cover just over 2.5% of Queensland, supported by NatureAssist incentive funding.
DocumentedSource
Victoria, Australia (Trust for Nature) · 1972 to 2023
More than 1,500 covenants over about 74,365 ha; rarely released and adaptable, but small coverage and little ongoing funding for landholders.
Peer reviewedSource
Armidale and Uralla, NSW, Australia (Northern Inland Koala Tender) · 2023 to 2024
4,148 ha approved for permanent protection on title, including 1,692 ha of koala habitat; nearly $9 million invested with annual stewardship payments (median $163 per ha per year).

Where it failed
Queensland: Bimblebox Nature Refuge, bought for conservation in 2000 with a federal grant on condition it be protected in perpetuity, still faced a coal exploration permit and a mine application before the Land Court, because nature refuges do not exclude mining. Victoria (Brugler 2023): after 50 years, about 1,500 covenants cover only 0.33% of the state; landholders get no ongoing payment and monitoring is light. British Columbia (Schuster and Arcese 2015): easements are about three times more cost-effective than buying land, but at high dispute and violation rates that advantage largely disappears. NSW: private-land investment has been undercut by continued clearing of unprotected land nearby.
