Crunching across a brushy, logged-over slope near Corvallis, Oregon, Reed Wilson points his trekking pole at an ancient Douglas fir in a neighboring patch of forest. The tree is more than an armspan in diameter, its toes decorated with saprophytic orchids and millipedes.
One of 117 behemoths among these otherwise young stands, this tree and 38 others also wear necklaces of pink tape. Tree-climbing citizen surveyors left them to mark the presence of red tree vole nests, explains Wilson, a gray-haired local jeweler and activist. The tiny rodents devour conifer needles and use the hair-like resin ducts to build pillowy abodes in the trees’ branches. Most vole business takes place high in the canopy — interlaced limbs offering access to other trees, food, mates and new homes. The vole is also favored prey for the threatened northern spotted owl, and its population here in the low-slung northern Coast Range is a candidate for endangered species protection.
The federal government set aside this area as part of a 10-million-acre network of reserves in western Oregon, Washington and Northern California, largely to protect species like spotted owls and voles whose old-growth habitat was being destroyed by logging. In 2009, though, the Bureau of Land Management proposed a commercial project to thin younger trees here, ostensibly to restore more diverse forest structure. And though the Benton Forest Coalition, to which Wilson belongs, and two other environmental groups forced the agency to leave intact forest around most of the vole trees, several stand alone amid logging slash, their tiny tenants marooned and more vulnerable to predation. “This was native forest,” regenerating from a 1931 wildfire, Wilson says. “It hadn’t been logged before.” More…
