Florida's open-space land-acquisition program is one of most aggressive in the country, with $3.7 billion paid for 3.8 million acres since 1972. Using data from the Conservation and Recreational Lands (CARL) program, hedonic analyses found that acquiring private lands with valuable natural resources, habitat for rare species, and important historical sites for public preservation is more costly. Development potential and pressure also increased acquisition costs. The presence of additional endangered natural elements and needing to contract with additional landowners, however, were found to decrease the cost. Results provide a basis for landowners and land-acquisition agencies to negotiate.
