Descriptions of fuels and their quantification are used in several aspects of forest management and research. However, collecting site-specific data can be tedious, time-consuming, and expensive. Fuel photo guides, with their pictorial catalogs and accompanying fuel descriptions and quantitative information, represent a quick and easy alternative to objectively assessing the characteristics of forest fuels in a given area. This report augments the existing fuel photo guides of North American forest stands and vegetation types. Summary information and color photographs are presented for a jack pine (Pinus banksiana Lamb.) – black spruce (Picea mariana (Mill.) BSP) chronosequence in the south-central part of the Northwest Territories, Canada. Eight stands, initiated after stand-replacing crown fires and ranging in age from 1 to 108 years, were documented. The information presented here includes a description of each site, quantification of fuels by fuel strata, vertical distribution of the ladder and crown fuels, and visual representations of the stands in the form of general profile and stereopair photos.
