A conservation easement limits certain uses of the land in order to advance one or more conservation objectives while keeping the land in the owner’s control. It is established by mutual agreement of a landowner and a private land trust or government.
The conservation easement is a tool for conserving land in the public interest that doesn’t rely on government regulations and that allows private landowners to maintain ownership and control of their land.
Tens of thousands of properties important to people—millions of acres of farms, forests, scenic hillsides, historic landscapes, green spaces in cities, etc.—have been conserved with conservation easements. While the first conservation easement was established in the late 19th century, the tool did not come into common use until the late 20th century.
A conservation easement is established by mutual agreement between a landowner and a private land trust or government. The easement limits certain uses of the land in order to achieve particular conservation objectives while keeping the land in the owner’s control. The owner may continue to use the land as the owner wishes—within the constraints agreed to when establishing the easement. As the holder of the conservation easement, the land trust has the right to block inappropriate uses of the land.
A conservation easement does not create a right for the public to access a property, unless the owner explicitly establishes that right.
The conservation easement, which is an interest in real property, continues in force no matter who owns the land in the future. Practically all conservation easements are designed to be perpetual; for nearly all land trusts and circumstances, this is non-negotiable.
A conservation easement can’t be created without a land trust or government that is willing to hold it. Land trusts working in a particular geographic area can be found at www.findalandtrust.org or, in Pennsylvania, at WeConservePA.org/groups.
Although usually not the determining factor in a landowner’s decision-making, federal income tax, estate tax, and potentially other tax benefits are available in conjunction with the donation and bargain sale of easements that meet certain requirements.
Soon after a landowner or land trust broaches the idea of creating a conservation easement, the land trust will want to talk with the landowner about the conservation objectives to be advanced by the easement. These objectives will be shaped by the character of the property, the mission of the land trust, and the wishes of the owner. For example, the land trust and owner might include any one or more of the following as conservation objectives:
Once the owner and land trust agree on the objectives, they typically discuss which uses of the land are and aren’t compatible with the objectives. Depending on the objectives, the owner and land trust may agree that restrictions such as the following may be necessary:
They may agree that the easement will need to clearly permit the owner certain uses of the land. For example, an owner may want to ensure that they can:
They also may agree that certain uses of the land might (or might not) be appropriate depending on the details and that the land trust should have the right to approve or disapprove an owner’s proposal to engage in such uses based on the land trust’s analysis of the potential impact on the protected natural resources.
Whether the landowner first approaches the land trust or the land trust approaches the landowner about a potential conservation easement, it is often advantageous for one or both parties to formalize their respective understandings of what each is—and is not—committing to as the conversations proceed and they devote more time and resources to the potential conservation endeavor. This formalization may take the form of a donation agreement, purchase option, sales agreement, or other form used by the land trust. The formalization ensures that the land trust doesn’t waste donor dollars on a project that the owner isn’t reasonably committed to seeing through to completion and, conversely, that the landowner doesn’t waste effort if the land trust is unlikely to find the owner’s needs compatible with the land trust’s aims.
The conservation objectives, restrictions, and permitted uses agreed upon by the owner and land trust are incorporated into a legal document usually provided by the land trust. Just as the standard document used to purchase a house is long, so too is the standard document used to create the conservation easement. This is necessary in order to responsibly address the complexities of the law and the many issues that may arise when land is to be conserved for the long run.
Fortunately, just as Realtors provide a time-tested standard sales agreement for transactions, so too do many land trusts. One prominent example is the Model Grant of Conservation Easement and Declaration of Covenants, a standard document to create conservation easements published by the Pennsylvania Land Trust Association. Land trusts across the country have adopted this model and adapted it for local use.
The planning of the conservation easement also requires documenting the conditions of the property in a baseline documentation report, subordination of the mortgage (if any) on the property, and other tasks, which the land trust will help the landowner understand early in their conversations. Depending on the project, survey work may be required and, if the owner intends to seek a tax deduction, an appraisal will be necessary.
After finalizing the easement document, the owner and land trust sign and record it at the county recorder of deeds office. With this action, the owner grants to the land trust the conservation easement, which gives the land trust the power and right to uphold the conservation objectives.
With the recording of the easement document, the land trust’s work has only just begun—and will never end. The land trust is now responsible for ensuring that all future owners respect the conservation objectives of the easement. The land trust’s stewardship work includes:
As a private, independent, charitable organization, a land trust, before accepting any particular conservation easement, will consider:
Landowners exploring whether to establish a conservation easement on their land will want to consider a number of factors including:
The owner’s aims should be compatible with the land trust’s goals and priorities. An owner who wants to protect their forested wildlife habitat may not be a good match for a land trust focused on preserving farmland for sustainable agriculture.
Conservation easements entail a lot of responsibility for their holders. A landowner who wants to ensure that a particular organization is the right one to hold an easement should check that:
Most conservation easements are donated by owners who wish to protect the land they love from inappropriate development. In certain narrow circumstances, easements are purchased at a bargain price or fair value. Donations and bargain sales that meet IRS requirements can result in federal tax benefits.
Some government programs purchase conservation easements. These programs generally have tightly focused purchase priorities and, especially for programs that pay at or near fair value, experience high demand, meaning long waits for owners who want to participate. A review of these programs is beyond the scope of this guide. (For a Pennsylvania example of a government program that purchases easements on productive farmland, see the guide Agricultural Conservation Easement Purchase Program. The guide Farm Preservation Options for Landowners compares this program to land trust easement work.)
Stewardship of an easement takes time and money. A land trust that doesn’t raise money to cover its perpetual stewardship responsibilities can’t assure that conservation will be lasting. For this reason, it is a normal practice for a land trust to make a stewardship funding arrangement with an owner to help with the land trust’s financial burden. This arrangement may involve one or more cash contributions by the owner at or following the establishment of the easement.
The planning of a conservation easement also involves costs to the land trust and owner. Again, the owner may be asked to help the land trust with its costs.
Since not all owners can afford to make cash contributions, the land trust might alternatively seek to arrange for payments by future owners of the land or find financial support from other individuals or organizations who want to see the conservation easement established.
Easement planning and stewardship expenses vary widely depending on the specifics of the project. The land trust that the owner is exploring a potential easement with is best positioned to estimate the costs for a particular project.
If a conservation easement is donated or sold at a bargain price to a qualified organization and the transaction conforms with federal tax rules, the donor may receive a federal tax deduction. Since the donor may deduct only up to 50% (100% if a qualified farmer) from their income each year, the donor can spread the deduction out over as many as 16 years.
Roughly approximated, the maximum value of the deduction equals the fair value of the land unencumbered by the easement minus the fair value of the land that would result if the easement were in place. The values must be determined by an appraisal that meets tax rule requirements and is completed by an appraiser qualified under the tax rules.
The cash value of the deduction—how much the landowner saves on taxes—would then be the gift’s value multiplied by the donor’s tax bracket. For example, a donor in the 35% tax bracket could save $140,000 on their taxes when making a conservation easement gift valued at $400,000.
Additional tax benefits may be available to those with high-value estates subject to the federal estate tax.
Several states offer income tax credits. Property tax reductions are also available in some locales.
This highly abbreviated summary leaves out myriad complexities. Seek advice from a tax advisor to fully understand the possible tax benefits.
 Although local, county, state, and federal governments may hold conservation easements, private land conservation as conducted by independent, charitable land trusts is the focus of this guide.
 Colorado, Georgia, New Mexico, South Carolina, and Virginia offer transferable tax credits, meaning donors can sell unusable credits to other taxpayers. Arkansas, California, Connecticut, Delaware, Iowa, Maryland, Massachusetts, Mississippi, and New York also offer some form of credits.
