“Scientists in the U.S. Northeast published two studies examining the impact of deer overpopulation on natural ecosystems in early March 2014. Scientists at Cornell University investigated disruptions by large numbers of deer to natural growth in developing forests. University of Pittsburgh researchers showed how large deer populations are causing an increase in garlic mustard, an exotic invasive plant, in forest understory fauna. In both instances, the root problem is overgrazing of native plants by deer that open up more growing space for invasive exotic plants that deer find unpalatable.”

NELSONVILLE, Ohio – Research beginning this week on the Wayne National Forest will explore whether a native fungus can help land managers rein in an aggressive, non-native invasive tree that has been steadily encroaching on Ohio forests, particularly in the southern half of the State.
Trial sites include the Wayne National Forest, Athens Ranger District-Marietta Unit; Tar Hollow, Perry, and Blue Rock State Forests; and the Wilds a private, nonprofit wildlife conservation center in Muskingum County. Joanne Rebbeck, a USDA Forest Service Northern Research Station scientist will inoculate Ailanthus trees with Verticillium nonalfalfae (V. nonalfalfae) to evaluate how effective it might be in controlling Ailanthus. Forty trees will be inoculated with the fungus at each of the five sites.
On the particularly hard-hit Marietta Unit, almost 3,000 seed-bearing Ailanthus located through aerial surveys across 124,000 acres, which is one reason to focus the study in this area because herbicide treatments on this large a scale would becost-prohibitive.
“Throughout Ohio, Ailanthus has the potential to replace oak and other native tree species and dramatically affect native food sources for wildlife,” said Tony Scardina, Wayne National Forest supervisor. “Research at the Wayne National Forest this summer will help assess the potential value of V. nonalfalfae as a non-chemical, sustainable means of controlling Ailanthus, which could be a first step in restoring healthy native forests.”
The effect of V. nonalfalfae, often called “Ailanthus wilt,” was first documented in Pennsylvania in 2002 by Penn State researchers. Rebbeck, shown here, has studied the fungus in the lab and greenhouse and has contributed to studies showing that V. nonalfalfae does not affect over 70 species of trees and shrubs, including Ohio tree species such as ash, beech, elm, hickory, and oak.
“In addition to studying the effectiveness of V. nonalfalfae as a biological control for Ailanthus, this research will also explore how native forests respond when Ailanthus is absent,” Rebbeck said. “Do native trees regenerate, or will another invasive species replace the Ailanthus?”
Ailanthus, also known as “tree of heaven,” is a native of Taiwan and central China that was introduced to the U.S. by a gardener in Pennsylvania in 1784. The tree is a master of regeneration, growing 3 to 4 feet in its first year, producing 300,000 seeds per female tree, and spreading through root systems. Ailanthus is often found in open spaces, but is increasingly found within disturbed forest sites.
“The aggressive growth habits of Ailanthus are a threat to the biodiversity of Ohio’s forests,” said Robert Boyles, Ohio Department of Natural Resources deputy director and state forester. “The results of this research could have a significant, positive, and lasting effect on forest health throughout the state.”

Hemlock Woolly Adelgid: Preparing Woodland Owners for Impacts to the Hocking Hills Region on October 26th
Eastern hemlocks play a key role in the ecology and economy of the Hocking Hills. These trees, however, are currently threatened by the recent discovery of the Hemlock Woolly Adelgid in Ohio and the Hocking Hills
Join us for a program designed to introduce home owners and woodland owners to the potential threats, impacts, and management issues presented by the Hemlock Woolly Adelgid in the Hocking Hills Region. You will also learn about the newly formed Hocking Hills Conservation Association http://hemlockhero.com and their efforts to combat this pest, and the efforts of the ODNR Division of Forestry to provide services to Small Woodlot owners in the Hocking Hills

Southeastern Ohio is blessed with an abundance of wildlife species from wild turkey and white-tailed deer to bobcats and Cerulean warblers. Many of Ohio’s woodland owners list wildlife as a key reason for owning their properties. “Enhancing Food Production for Woodland Wildlife”, an educational program designed to provide woodland owners with the knowledge to improve wildlife habitat on their property, will be offered at the Vinton Furnace State Forest on Friday, October 11 from 9 am to 3:30 pm. Participants in this program will:
• Learn about the wide variety of food for wildlife that is produced by native trees and shrubs
• Understand the nutritional needs of some common woodland wildlife species
• Visit field sites which demonstrate practices that enhance wildlife food production
• Discuss and practice techniques that can enhance the production of food for wildlife
• Spend “A Day in the Woods” with foresters and Ohio’s…

“Identifying and Controlling Invasive Plants” program offered to woodland owners in SE Ohio at the Vinton Furnace State Forest on Friday, July 12th
Are you seeing new plants encroaching on your woodland property in southeastern Ohio but don’t know what they are? Do you already know about invasive plants but don’t know how to control them? The program “Identifying and Controlling Invasive Plants” will take place at the Vinton Furnace State Forest, near McArthur, on July 12 from 9 am to 3:30 pm.
This landowner program is designed to help them learn how to identify and control common invasive plants in their woodlands. Throughout the day there will be opportunities to visit sites outdoors with invasive plant specialists to see these plants and see demonstrations of various control techniques.
“Identifying and Controlling Invasive Plants” and the “2nd Friday Series” are sponsored by the Education and Demonstration Subcommittee of the Vinton Furnace State Experimental Forest with support from the ODNR-divisions of Forestry and Wildlife, US Forest Service, Vinton County Soil and Water Conservation District…

Connecticut is relatively progressive in it’s invasive plant legislation. Here is an interesting article on some bamboo legislation that might possibly pass.
