ARIZONA — For the first time in months, Forest Service timber managers last week attended a Natural Resources Working Group meeting on the continuing effort to restore Northern Arizona forests and protect communities including Payson, Show Low, Pinetop and Pine. Local officials and logging operators said they are still searching for ways to handle millions of tons of low-value brush, slash and small trees that crowd the region’s overgrown ponderosa pine forests. The group, formed through the Eastern Arizona Counties Organization, meets regularly with industry representatives and Forest Service staff. …The Four Forest Restoration Initiative (4FRI) completed about 18,000 acres of thinning in the past year. Mass layoffs and the shutdown limited collaboration and fieldwork. …Pascal Berlioux, executive director of the Eastern Arizona Counties Organization, said a major problem was reduced production at the Lignetics plant in Show Low, which normally buys large amounts of biomass for wood-pellet manufacturing.
