92 YEARS OF TREE GROWTH & DEATH The City of Arcata Environmental Services Department’s Forest Ecology Fall Lecture Series presents “Ninety-Two Years of Tree Growth and Death in the Arcata Community Forest” by Benjamin Iberle of Humboldt State’s Forestry & Wildland Resources Department, Thursday, Nov. 30 at 6 p.m. at the Arcata Marsh Interpretive Center, 569 South G St. Two one-acre observation plots in the Arcata Community Forest established in 1923 by Dr. Woodbridge Metcalf of UC Berkeley provide a truly unique opportunity to examine the development of such a forest over more than 90 years. Humboldt State researchers have surveyed the plots using modern methods and assembled a complete dataset from 1923 to 2015. Recent Master’s graduate Ben Iberle will share the results of their efforts and compare the trajectory of these plots to other second-growth examples and to characteristics of old-growth forests. Call (707) 826-2359 to reserve or seat, or just show up.
