A program authorized by 1990 farm bill (P.L. 101-624) to provide long-term protection for wetlands. Producers enrolling in the program must agree to implement approved wetland restoration and protection plans. In return, participating producers receive payments based on the difference in the value of their land caused by placing an easement on a portion of it. The program reached its authorized enrollment ceiling of 1,075,000 acres before the 2002 farm bill (P.L. 107-171) was acted upon. The 2002 legislation reauthorized the program with mandatory funding from the Commodity Credit Corporation (CCC) through FY2007, and set a maximum enrollment ceiling of 2.275 million acres (and with an annual enrollment ceiling of 250,000 acres).
