Within the Sub-Boreal Spruce Zone (SBS) of the Prince Rupert Forest region, the forest manager encounters a considerable range of stand types, forest productivities, and stand responses to various kinds of treatment. Such variability arises not only from different stand histories but also from intrinsic differences in the climate, topography, geology, and soils of various forests sites or ecosystems. This Field guide aims to provide a practical, efficient tool to identify decent intrinsically different ecosystem units in the field.

This guide contains information, condensed for field use, on the identification and interpretation of biogeoclimatic and ecosystematic units in the Coastal Western Hemlock Zone, Northern Drier Maritime Zone (CWHf). The area covered includes most of the low and middle elevation forests of the central part of the Kalum Timber Supply Area and some of the middle elevations of the westernmost Kispiox Timber Supply Area.

This guide has two main goals: to assist users in classifying sample forest ecosystem sites in the field in the south-east Prince George Forest Region; and to provide interpretations for these site units that will assist in preparing management prescriptions. Following the introduction is a brief discussion of the biogeoclimatic classification system. Chapter 3 contains procedures for site description, identification, mapping, & interpretation. Chapters 4 to 11 present information about the biogeoclimatic units in the Region, tools for identification of biogeoclimatic & site units, descriptions of the site units, and direct management interpretations for the identified site units. Chapter 12 provides indirect interpretations for silvicultural systems and site preparation options, as well as some basic information on ecosystem management.

This guide is a technical support document intended to help forestry practitioners collect the information they need to prepare a silvicultural treatment regime and silviculture prescription in accordance with British Columbia Forest Practices Code legislation. It deals primarily with the collection & stratification of site-specific field data. After information on office preparation, stratification, plot establishment, and mapping procedures, the guide presents data collection procedures for silviculture prescription field forms. Copies of forms are included in the appendix. The data cover such matters as site characteristics, understorey & overstorey, soils, riparian & watershed values, soil & fire hazards, silvicultural systems & objectives, harvesting, forest health, stand tending, and forest resource values.
