BOISE, Idaho – Idaho Gov. C.L. “Butch” Otter has put his signature on a four-state pact that aims to help restore land burned in this summer’s wildfires and to promote cross-border cooperation to prevent future catastrophic blazes. The agreement also involves Nevada, Utah and Wyoming, though those states still must sign. Otter says the agreement would help the states cooperate to reduce the annual threat of wildfire. Last July’s Murphy Complex blaze on the Idaho-Nevada border destroyed an area larger than Rhode Island. Otter also says he’ll join volunteers who will climb into the hills near Boise next week to collect wild plant seeds to be used on charred rangeland destroyed in this year’s fires.
