The survival of some species of oaks, among them black oak, have been threatened as forested areas in North America are cleared for agriculture, urban development, and other forms of development. It is a major goal of many forest managers to maintain current populations of oak (Quercus spp.) for timber, wildlife, and conservation biology. Currently, black oak is distributed throughout …

Preventing Forest Tree Illness
Do not wait to act on insect and disease issues until after you see dead branches. Look for visible symptoms or signs of tree illness and learn how to prevent a favorable environment for organisms that harm trees. It is important to understand that successful methods for minimizing forest insect and disease problems are usually preventative, occurring before problems are noticed. Monitoring your forest for …
Regional Climate Hub Assessment of Climate Change Vulnerability and Adaptation and Mitigation Strategies
USDA’s Regional Climate Hubs were established in February of 2014 to deliver science-based knowledge, practical information, and program support to farmers, ranchers, forest landowners, and resource managers to enable climate-informed decision-making in light of the increased risks and vulnerabilities associated with a changing climate. As part of their function, the Hubs were tasked with providing periodic regional assessments of risk and vulnerability to production sectors and rural economies, building on material provided under the National Climate Assessment conducted through the …

Oak decline is the name given to a slow-acting disease complex stemming from interactions between biotic and abiotic stressors of oaks (Quercus spp.). Abiotic factors that contribute to oak decline include tree maturity, low site productivity, drought, and spring frost. Biotic factors include root diseases such as Armillaria root disease (Fig. 1) (Armillaria spp.), canker causing fungi such as Hypoxylon canker (Fig. 2) …
Overview of the Effects of Climatic Variability and Change on Forest Ecosystems in the Midwest United States
The Global Change Research Act of 1990 requires the U.S. Global Change Research Program (USGCRP) to produce the National Climate Assessment (NCA) for the President and Congress every four years, analyzing the effect of global change on multiple sectors and regions in the United States and projecting major trends forward for up to 100 years. Effects on Climatic Variability and Change on Forest Ecosystems: A Comprehensive Science Synthesis for the U.S. Forest Sector (PNW-GTR-870) serves as the U.S. Forest Service …

Climate Change Impacts on Forest Diseases
Written by Tom DeGomez, University of Arizona
Forest disease organisms and abiotic occurrences that lead to diseased trees are common in terrestrial ecosystems. Most of the disease organisms within forests are essential to the health of the system and are present at background levels, generally occurring on weakened members within a forest stand. Occasionally, diseases can overcome a forest system and a stand-replacing event will occur, but this is a rare event even in the least resilient forests. The full …
Climate Change Impacts on Forest Insects
Excerpt from: Régnière, J. 2009. Predicting insect continental distributions from species physiology. Unasylva. 60:37-42.
Insects constitute the most diverse form of animal life in terrestrial ecosystems. Most species are innocuous but essential components of natural ecosystems. Because they are cold-blooded, the rates of key physiological processes in their life cycles are determined by environmental conditions, especially temperature and precipitation. In general they have short generation times, high fecundity, and high mobility (either through their own faculties or aided by wind, …
Wildfire and Climate
Adapted from: Rogstad, Alix; Crimmins, Michael; and Garfin, Gregg. 2006. Climate change and wildfire impacts in Southwest forests and woodlands. University of Arizona College of Agriculture and Life Sciences. Publication No. az1425
Wildfire requires three things to burn: an ignition source, fuel, and oxygen. If one of the three requirements is removed, the fire activity will be …
