Concern over the condition of forests in relation to natural and manmade stresses has led to an interagency Forest Health Monitoring program. To improve the efficiency of forest monitoring, the forest group of EPA's Environmental Monitoring and Assessment Program conducted a field test of selected measurements. The objectives of the field test were to decide statistical, plot, design, and logistical issues. Measurements of soil, vegetation structure, foliar chemistry, mensuration, light transmittance, and visual symptoms were made at 40 plot locations in New England and Virginia. The data were used to derive optimum multi-stage sampling intensities for different cost assumptions. The field test also provided a realistic test of logistics. The numbers of different types of measurements are recommended for monitoring in these forest types and regions. Specific recommendations are also made to streamline field sampling. In general, the plot designs and sampling intensities currently used for forest modeling are adequate for the measurements tested.
