WELC is technically a public interest law firm, meaning it does not charge for legal services, and is instead funded by donations.
Some of the center’s legal victories include helping restore protections for the gray wolf, preventing the extinction of the northern spotted owl, and working to prevent 6 billion tons of Powder River Basin coal from being mined.
