In 2006 The Nature Conservancy won a legal action to force the Pala Band of Mission Indians to pay them $545,000 for unknowingly violating a provision of the Clean Water Act. The tribe had allowed members to conduct a mining operation on tribal land and the water runoff affected neighboring land owned by The Nature Conservancy. When the Nature Conservancy took legal action, the Native Americans were outgunned in terms of legal representation and legal defense funds. When the verdict was announced Tribal leaders did not know how they would raise the money to pay the multi-billion dollar Nature Conservancy from their over-strained budget. The Nature Conservancy does not need the money from the lawsuit and admitted that it planned to use the money to buy even more land near the reservation.
Apparently The Nature Conservancy’s commitment to preservation does not include preservation of the welfare of Native Americans.
