Book Description
Ozone is a highly toxic air contaminant that has been shown to decrease tree growth and cause signifi cant disturbance to forested ecosystems. Ozone also causes distinct foliar injury symptoms to certain species (bioindicator plants) that can be used to detect and monitor ozone stress (biomonitoring) in the forest environment. In the early 1990s, the U.S. Forest Service, in partnership with the U.S. Environmental Protection Agency, developed and implemented a suite of forest health indicators to respond to emerging demands for a comprehensive assessment of the health of U.S. forests. This report focuses on the states in the Northern Research Station-Forest Inventory and Analysis region, which has the longest record of ozone biomonitoring in the country, from 1994 through 2010. The results of 17 years of ozone injury detection provide indisputable evidence that ozone-induced foliar injury symptoms occur routinely on ozone-sensitive bioindicator plants across much of the forested landscape and in areas previously thought to be relatively ozone free. This report provides state-level information on where ozone stress occurs and whether ozone stress is increasing or decreasing over time. It also provides state-level estimates of the acres of forest land and volume of ozone-susceptible species at risk of ozone impact.

Book Description
The American chestnut, whitebark pine, and several species of ash in the eastern United States are just a few of the North American tree species that have been functionally lost or are in jeopardy of being lost due to outbreaks of pathogens and insect pests. New pressures in this century are putting even more trees at risk. Expanded human mobility and global trade are providing pathways for the introduction of nonnative pests for which native tree species may lack resistance. At the same time, climate change is extending the geographic range of both native and nonnative pest species. Biotechnology has the potential to help mitigate threats to North American forests from insects and pathogens through the introduction of pest-resistant traits to forest trees. However, challenges remain: the genetic mechanisms that underlie trees' resistance to pests are poorly understood; the complexity of tree genomes makes incorporating genetic changes a slow and difficult task; and there is a lack of information on the effects of releasing new genotypes into the environment. Forest Health and Biotechnology examines the potential use of biotechnology for mitigating threats to forest tree health and identifies the ecological, economic, and social implications of deploying biotechnology in forests. This report also develops a research agenda to address knowledge gaps about the application of the technology.

Book Description
This report by the Nat. Science and Tech. Council¿s U.S. Climate Change Science Program (CCSP) is part of a series of 21 reports aimed at providing current assessments of climate change science to inform public debate, policy, and operational decisions. These reports are also intended to help the CCSP develop future program research priorities. The CCSP¿s guiding vision is to provide the Nation and the global community with the science-based knowledge needed to manage the risks and capture the opportunities associated with climate and related environmental changes. This report assesses the effects of climate change on U.S. land resources, water resources, agriculture, and biodiversity. It was developed with broad scientific input. Illus.
