What it does
This bill creates a new federal income tax credit allowing landowners to claim a dollar-for-dollar tax deduction equal to the fair market value of land they donate or restrict for conservation purposes along National Scenic Trails. The credit applies to donations of trail corridors (typically 50–2,640 feet on each side of a designated trail) and can be carried forward for up to 10 years if unused. Landowners retain the right to continue recreational or agricultural use of the land as long as it does not impair conservation interests.
Why we flagged it
The bill's core mechanism is a tax credit (not a direct subsidy or grant) designed to incentivize private conservation contributions. It is structured as a voluntary election by landowners and does not mandate any action, making it a market-based conservation tool rather than a regulatory mandate.
What the text implies
- The 'highest and best use' valuation standard may inflate appraised land values, increasing the tax credit amount and reducing federal revenue beyond the conservation benefit achieved.
- Landowners can continue recreational and agricultural use (including motor vehicle use) on restricted land, potentially limiting the conservation impact while still claiming the full tax credit.
