The Northwestern Ontario Forest Ecosystem Classification (NWO FEC) provdes a framework that forest managers can use for classifying forest soils and vegetation (S-Types and V-Types) and for land management applications. For many forest management uses, NWO FEC V- or S-type information must be mapped at a scale compatible with data collection by ground survey. However, ground surveys are typically costly or difficult, and a photointerpretation procedure for typing soils or vegetation would be useful. This study was undertaken to develop a reliable methodology for interpreting NWO FEC S- and V- types using aerial photos. The study area was the Aulneau Peninsula along the Lake of the Woods, and study methods included a review of existing information, a field reconnaissance, and development of photinterpretation keys. This report presents the study results and the interpretation procedure developed. photos together with other available information.

Provides a case study of the development of aerial photo interpretation (API) keys that may assist resource managers in the identification of the classification units of the Northwestern Ontario Forest Ecosystem Classification (NWOFEC) on 1:15,840 scale black & white photos. The first part contains a brief historical overview of site classification activities in Ontario, and describes the NWOFEC system, some of its current applications, and past efforts to interpret photos and map the classification units. Basic techniques for interpreting landform, soil, and vegetation features on intermediate-scale black & white aerial photos are also presented. The method of developing API keys is then detailed, including phases of data collection, photo interpretation, and key construction. The final section demonstrates all aspects of development of the keys, including description of the study area's soil and vegetation characteristics, the creation of toposequence models, the framework for each key, and photo stereograms that illustrate a variety of interpreted features. The full API keys are presented in stand-alone format in appendices along with tips for applying them.

Guide to assist in the application of the Northwestern Ontario forest ecosystem classification to forest management in northwestern Ontario. Interpretations relate vegetation, soil, site, and climatic factors to limitations or opportunities for forest management. The guide introduces the concept of forest ecosystem interpretations; presents the concept as a method of applying the classification to site-specific management through a set of generalized treatment units that may be further adapted to accommodate local variations in site or climate; describes some basic silvicultural interpretations, followed by interpretations for wildlife; and deals with incorporation of the system into operational forestry surveys.
