Northern Plains is the only conservation group in Montana that truly works in rural areas on natural resource and ag issues. Northern Plains has been around for almost 40 years now and it takes a successful well-run organization to last that long. The people engaged in this organization are far from your typical environmentalists and many are 3 and 4th generation Montanans. Also, this group is truly grassroots and is entirely member-run.
I highly recommend supporting Northern Plains and have been very satisfied in working with them.
