Senators Ron Wyden of Oregon and Mike Crapo of Idaho introduced legislation on Thursday to make the Secure Rural Schools program that expired at the end of fiscal year 2018 permanent by creating an endowment fund.  The two senators say the Forest Management for Rural Stability Act would provide stable, increasing and reliable funding for county services.  The Secure Rural Schools and Community Self-Determination Act Wyden co-authored was enacted in 2000 to financially assist counties with public, tax-exempt forestlands.  Critical services at the county level have historically been funded in part with a 25 percent share of timber receipts from federal U.S. Forest Service lands, and a 50 percent share of timber receipts from federal Oregon and California Grant Lands managed by the U.S. Bureau of Land Management.  As those revenues have fallen or fluctuated due to reduced timber harvest and market forces, SRS payments helped bridge the gap.  But in recent years Congress has allowed SRS funding to lapse and decrease, creating uncertainty for counties as they budget for basic services.
