LAND

Landmark win for the wild Hatchie

A 7,418-acre expanse of old-growth bottomland hardwood forest along the Hatchie River has been permanently protected through a partnership with The Conservation Fund and the Tennessee Wildlife Resources Agency (TWRA). This marks the largest land acquisition The Nature Conservancy in Tennessee has undertaken in West Tennessee over the past 25 years. The protected area spans Haywood, Madison and Hardeman counties.

The Hatchie River—the last free-flowing river in the Mississippi River Basin—plays a vital role in restoring floodplain function, filtering water and providing habitat for migratory birds and native wildlife. This landscape is a biological treasure, supporting more than 100 fish species, 11 types of catfish, 35 mussel species and more than 250 bird species, including Swainson’s and cerulean warblers.

WATER

Two barrier removals in one year

Harms Mill Dam on the Elk River and the Lower Citico Creek Dam in the Cherokee National Forest have been removed. These high-priority projects are reconnecting aquatic habitats, improving public safety and restoring the natural flow of water across some of Tennessee’s most ecologically significant rivers.

The removal of Harms Mill Dam reconnected more than 1,100 stream miles, opening habitat for 46 species of greatest conservation need, including the endangered boulder darter. The removal of the Citico Creek Dam reconnected more than 38 miles of stream, restoring habitat for 67 fish and mussel species, including the federally endangered smoky madtom, Citico darter and yellowfin madtom.

Quote: Laurel Creech

2025 was a remarkable year for conservation in Tennessee. I’m deeply grateful for the dedication of our staff, trustees, partners and supporters who helped accelerate our work across land, water and climate to advance TNC’s 2030 goals.

CLIMATE

Policy progress in a changing landscape

In 2025, The Nature Conservancy faced major policy challenges as federal and state programs critical to conservation came under threat. Rising to meet these challenges, TNC coordinated a nationwide campaign to defend public lands, mobilizing members to send 100,000 letters to Congress and successfully blocking proposals to sell public resources. These efforts underscored the power of policy as a tool for conservation, driving strong investments in forests, wildlife, water and climate.

Key wins included safeguarding wetlands and advancing water security through the Duck River Watershed Planning Partnership. Working with lawmakers and partners, TNC helped retain protections for high-quality wetlands, preserving thousands of acres of vital habitat. Meanwhile, recommendations for the Duck River plan—backed by nearly $90 million in state funding—set a model for watershed management across Tennessee. Together, these achievements highlight how collaboration and persistence can protect nature and people while building momentum for the future.

BIODIVERSITY

Conserving Tennessee’s hidden worlds

Tennessee’s underground ecosystems are among the most biologically and culturally rich in the country. The Nature Conservancy’s Cave and Karst Program works to protect these fragile environments and the bat species that depend on them. In 2025, our team visited 47 caves during winter bat surveys, documenting a 38% increase in tri-colored bat counts across 26 sites—an encouraging sign for a species previously down by over 90%. We also identified new Indiana bat roosts, expanding known habitat for this endangered species.

Our research uses the MOTUS Wildlife Tracking System and Bluetooth transmitters to study bat migration and landscape use. In September, we set a record by tagging 120 bats in two nights with partners the Tennessee Wildlife Resources Agency (TWRA) and the Tennessee Valley Authority (TVA). One tagged gray bat traveled more than 165 miles, offering new insights into movement patterns and conservation needs.
