September 13, 2019 - By Project Learning Tree Coordinator Page Hutchinson Look A Little Closer… Although I work for the Virginia Department of Forestry, my job doesn’t actually allow me much time in the forest. Being a tree hugger from way back, I take as many opportunities as I can to get in the forest. On the recent Labor Day holiday, my friend Karen and I went for a hike on the Graves Mill... Read More
September 11, 2019 - By Area Forester Lisa Deaton Dung Beetles A local farmer asked me to examine a 40-year-old stand of loblolly pines to see if they were large enough to harvest. A corn field was located in the center of the property and we noticed some very fresh deer scat along the field edge. On the way back to the truck we saw something moving on the ground. It was a dung... Read More
July 23, 2019 - by DOF Forest Health Program Manager Lori Chamberlin The yellow-poplar weevil has made its presence known again in southwest Virginia. This native insect generally causes very little damage, but the population increased enough this summer to have a noticeable impact on yellow-poplars in the southwest part of the state. The weevils are black and small, only about 1/8th of an inch long. Since this pest is a weevil, it has... Read More
March 13, 2019 - The southern pine beetle typically gets all the attention, but there are other native bark beetles in our forests that often go unnoticed. One such beetle is the hickory bark beetle, Scolytus quadrispinosus. Adults are black, stout, and small – about 1/5 inch long. They fly to the tops of trees and feed on terminal growth, and then bore into the bark of trunks and branches to lay eggs. Females... Read More
February 22, 2019 - The southern pine beetle (Dendroctonus frontalis) (SPB) is a small, seemingly innocuous beetle that brings new meaning to the phrase “small but mighty.” These beetles are known as the most destructive native forest insect in the Southeastern United States. While a single adult beetle is only about 1/8 inch long, the ability to aggregate quickly means these tiny insects can overtake a pine tree’s defenses in a short period of time.... Read More
January 24, 2019 - Each month, Field Notes will bring you news from our forest health team. We kick off 2019 with a focus on winter activities and the hemlock wooly adelgid. What do forest entomologists do in the winter? We look for hemlock woolly adelgid! The Forest Health program staff at DOF surveys for many forest pests throughout the year, but the hemlock woolly adelgid is unique in that it is most active... Read More
November 20, 2018 - by Forest Health Specialist Katlin Mooneyham Here in the forest health program at DOF, we spend a lot of time talking about bad bugs and how to kill them. Much of our time working with landowners and other forestry professionals is spent identifying pests, giving management recommendations and, in some cases, even treating trees against a variety of problematic insects. The emerald ash borer, an insect that originates in Asia,... Read More
September 20, 2018 - by Area Forester Lisa Deaton Boogie Woogie Aphids Near the end of August, beech blight aphids, Grylloprociphilus imbricator, appear on American beech trees. They are easiest to find by locating patches of black sooty mold on the ground underneath infested beech trees. In the photo above, the orange fungus on the right was the first thing I noticed. Once I saw the sooty mold to the left, I looked up,... Read More
December 19, 2017 - by Urban Forest Conservationist Jim McGlone While leading a forest hike with a landowner and group of her friends, I was brought to a small group of pin oaks that had many of the growths pictured here. The landowner was concerned that it was a disease that would spread and kill all her trees. This growth, and others like it, are called galls. Galls form when an insect, usually a small... Read More
November 8, 2017 - Snack Time by DOF Area Forester Lisa Deaton Last week I was asked to see if a 16-year-old loblolly pine plantation had grown large enough for a commercial thinning. I was perplexed to find what looked like pieces of honeycomb on the ground. There were no large hollow trees nearby, just young, solid pine trees. Then I noticed that there were several pieces of it scattered around a nearby hole... Read More
