Forest Pest Images A Guide to Common Forest Pests in Georgia Terry Price, Forest Health Specialist, Georgia Forestry Commission Littleleaf Disease of Pine Around 1936 many of the shortleaf pine stands that had seeded-in on abandoned farm lands in the Piedmont regions of Georgia were characterized by trees having yellow-green foliage and unusually short needles (Figure 52). These trees were best described as having littleleaf symptoms; hence, the name littleaf disease. Many of the stands were 20- to 30-years-old. Further investigations associated the syndrome with soil series such as Wilkes, Mecklenburg, Tatum, Orange, and Vance. The sites were severely eroded due to previous agricultural activities and subsequent abandonment. The topsoil was almost completely eroded away. On such sites tree roots were weakened by heavy clay subsoils with poor internal drainage. Figure 52 - Symptoms of littleleaf are fading crowns, numerous cones, and short stunted needles and twigs. Photo by USFS Archives Research then and more recently has identified at least two soil-borne fungi associated with littleleaf;

However these forests are not without occasional blight. A variety of pests including deer, insects and disease occur in Pennsylvania woodlands. This webpage will serve as a educational link to deal with woodland pest management. Deer Increasing numbers of white-tailed deer in Pennsylvania's forests and urban areas impacts the success of tree seedling establishment. Deer overpopulation is problematic because they tend to strip their habitat of its life-supporting qualities, not just for deer, but for many woodland wildlife species. White-Tailed Deer Quality Deer Management Association (QDMA) is a non-profit wildlife conservation organization dedicated to ensuring a high-quality and sustainable future for white-tailed deer and white-tailed deer hunting. The QDMA promotes safe and ethical hunting, involvement in education and management, stewardship and appreciation of all life.

85. Inland Forest Management, Consulting Foresters (Published by Inland Forest management, Inc.) Biggest Forest pest? What pestproblem has the greatest influence on the health of Inland Northwest forests? http://www.inlandforest.com/P07-pest.html

Home Company Profile Forestry ... Links Articles from Tree Talk (Published by Inland Forest Management, Inc.) Biggest Forest Pest? What pest problem has the greatest influence on the health of Inland Northwest forests? That is the question I asked myself when considering what subject to address in this article. Bark beetles? Stem decays? Root diseases? Needle casts? Dwarf mistletoes? Rusts? The list to consider goes on and on. From a historical perspective, many foresters would argue that white pine blister rust has had the biggest impact. Because of this introduced disease, as well as logging practices, the amount of white pine in our damp forests has been reduced from about 50 percent historically, to about 3 percent today. Fortunately, with increased knowledge of our forests, modern day foresters are working to reverse this trend. For example, efforts are underway to plant blister rust resistant white pine seedlings. When I think of family forests and the most serious pest I encounter on these ownerships, one pest is commonly at the root of the problem - root disease. This fact was brought home to me earlier this year when I walked over a large private ownership and marveled at how little root disease was present. Except for pure pine forests, it seems I can always find root disease on a property of any significant size. Unfortunately, root disease does decimate many of our forests. Areas of the Inland Northwest have the dubious distinction of containing some of the largest root disease centers in the world. In fact, many knowledgeable people currently consider the largest living organism to be a single root disease fungus that covers 2,200 acres in eastern Oregon!

PATHOLOGY, PESTS AND DISEASES The underlying research theme of the Entomology and Plant Pathology Department is the integrated management of pests and diseases of perennial crops which includes pest and disease detection and diagnosis, epidemiology, pathogen biology and molecular typing and disease control of perennial horticultural crops. With the exception of research programmes on bacterial canker and fungal diseases of Prunus, most of this research is applied to fruit trees and perennial herbaceous crops. Nevertheless, this expertise is directly applicable to forest trees. Bacterial, fungal and viral pathogens : Bacterial Canker of cherry: biology, epidemiology, molecular finger printing, resistance (MAFF programme); the fungal programme includes molecular detection, quantitative epidemiology, control and modelling of fungal diseases on perennial crops. Work on leaf spots and fungal die back of cherry is augmented by major research programmes on fungal canker and Verticillium . Detection, characterisation and epidemiology of viruses of fruit crops.

Home Quick links England Forestry strategy ... People, trees and woodlands Protecting trees Sustainable forest management Woodland biodiversity Protecting trees Summary Promoting environmentally acceptable measures of preventing and controlling damage to Britain's trees Improving the effectiveness of the management of both native and newly established exotic problem species is a major focus of our research. Our approach is to understand the nature and reasons for the observed problems and to apply this knowledge to sustainable management of the organisms concerned. The ever growing global trade in plants, timber and the use of wood-based packaging material provide many pathways for pests and pathogens to escape their native habitats and enter new areas. Over the past decade, several new pests and diseases have been found in the UK, and some have established with serious economic consequences. Forest Research has several research programmes aimed at understanding and assessing the risk that some of these organisms can pose. Other key programmes form an important line of defence in monitoring any changes in the health of our trees as well as providing advice on common tree disorders and how to manage them. Awareness of the impact of climate change on the severity of some of our existing pest and disease problems is also crucial, since climate has a major influence on behaviour and population dynamics of many organisms, both positively and negatively. Effective control methods must be practical at a range of spatial scales, while also conforming to woodland certification demands to minimise chemical use.
