Book Description
"The Forest Health Monitoring (FHM) Program's annual national report uses FHM data, as well as data from a variety of other programs, to provide an overview of forest health based on the criteria and indicators of sustainable forestry framework of the Santiago Declaration. It presents information about the status of and trends in various forest health indicators nationwide and uses statistically valid analysis methods applicable to large-scale ecological assessments. Five main sections correspond to the Santiago criteria: Biological Diversity, Productive Capacity, Health and Vitality, Conservation of Soil, and Carbon Cycling. A variety of indicators contribute information about the status of each forest ecosystem considered. Many indicators use data collected from ground plots. Such indicators include species diversity (tree and lichens), bioindicator species (lichens and vascular plants sensitive to ozone), changes in trees (crown condition, damage, and mortality), physical and chemical soil characteristics, and aboveground and belowground carbon pools. Additional information about forest health status and change is derived from data that are used to measure forest extent; data about insects and pathogens; and remotely sensed and/or ground-based data about forest fragmentation, fire, and air pollution. A sixth section presents and discusses a multivariate analysis of the indicators. The technique provides a composite picture of forest health, based on statistically significant principal components."--P. ii.

Book Description
Different monitoring initiatives have been undertaken in Canada and the United States since the 1980s at national and regional scales. In the United States, starting in 1990, partners from federal and state agencies established the Forest Health Monitoring (FHM) program with the goal of monitoring and evaluating the status, conditions, and trends in indicators of forest health. The FHM program has evolved into a system where FHM plots are integrated with the national Forest Inventory and Analysis program. In Canada, early attempts can be traced back to the 1980s with the Acid Rain Early Warning System. After its ending, Canadian forest monitoring was mostly carried out within the redesigned National Forest Inventory, Ecological Monitoring and Assessment Network, and regional initiatives. One of them, implemented in the Athabasca Oil Sands Region of Alberta since 1997, is presented here.
