Book Description
The objective of this paper is to provide a global review of the non-wood uses of conifers. For the purposes of this paper, conifers are defined as trees and shrubs of the botanical orders Coniferales, Taxales and Ginkgoales (Rushforth 1987). Although some services are briefly mentioned, the focus of this paper is on products which conifers provide species, which are important sources of non-wood forest products, and places where these products are harvested. With the exception of essential oils, which can be obtained from several parts of the tree, the products described are organized by the part of the tree from which they are obtained (e.g. foliage, bark and roots, resin, seeds and cones). Where possible, data on levels of production and international trade are presented. Problems associated with the sustainable management of these products and compatibility or conflicts with other land uses are also presented. Both contemporary and historical or traditional uses of non-wood products from conifers are discussed.

Book Description
The Forest Inventory and Analysis (FIA) Program of the Forest Service, U.S. Department of Agriculture, conducts a national inventory of forests across the United States. A systematic subset of permanent inventory plots in 38 States is currently sampled every year for numerous forest health indicators. One of these indicators, crown-condition classification, is designed to estimate tree crown dimensions and assess the impact of crown stressors. The indicator features eight tree-level field measurements in addition to variables traditionally measured in conjunction with FIA inventories: vigor class, uncompacted live crown ratio, crown light exposure, crown position, crown density, crown dieback, foliage transparency, and crown diameter. Indicators of crown health derived from the crown data are intended for analyses at the State, regional, and national levels, and contribute to the core tabular output in standard FIA reports. Crown-condition measurements were originally implemented as part of the Forest Health Monitoring (FHM) Program in 1990. Except for crown diameter, these measurements were continued when the FIA Program assumed responsibility for FHM plot-based detection monitoring in 2000. This report describes in detail the data collection and analytical techniques recommended for crown-condition classification.
