SB 2970 seeks to enhance the Texas Farm and Ranch Lands Conservation Program by expanding the scope of agricultural conservation easements. The bill amends existing law to prioritize the protection of large tracts of open-space land at risk of fragmentation or development. It grants additional powers to the program's council, including the ability to establish protocols for purchasing easements, adopting best practices for evaluating easements, and coordinating public and private funding. Furthermore, the bill outlines new criteria for awarding grants, emphasizing the protection of agricultural productivity, habitat conservation, and leveraging state funds with additional public or private contributions.
