AbstractThe beetle (Coleoptera) fauna of a black spruce [Picea mariana (Mill.) BSP] – tamarack [Larix laricina (DuRoi) K. Koch] – Sphagnum bog in Algonquin Provincial Park, Ontario, was sampled from early June to mid-August with yellow pan traps and emergence traps. The yield was 5734 beetles, in 30 families. Ptiliidae was the most numerically abundant and Staphylinidae was the most taxonomically diverse. Carabidae was second in diversity and third in numerical abundance. The abundance and ecological implications of some individual species are discussed. Few of the species are bog-specific. The faunal composition suggests that the bog is in a late-succession phase and that most of the beetle species are derived from adjacent habitats.

Several xylophagous insect species have adapted to recurrent fires in boreal forests and use high-quality habitats created by these disturbances. To characterize the xylophagous insect assemblages of fire-killed black spruce and their patterns of substratum use, eighty-four 40 cm long bole segments were cut in 2000 and 2001 according to tree diameter, segment height, and fire severity criteria in a 1999 burn in the Grands-Jardins provincial park, Quebec, Canada. The segments were suspended in rearing cages, and neonates were collected until November 2001. The cerambycid Mono chamus scutellatus (Say) and the scolytids Dryocoetes affaber (Mann.) and Polygraphus rufipennis (Kirby) were the most common beetles collected. For all common taxa, more neonates emerged from larger-diameter trees. Few neonates emerged from the upper parts of the trees, and none of the species were specialist of the upper parts of the tree. Fire severity had a drastic effect, and heavily charred trees yielded very few insects. The effect of fire severity on insect colonization density varies widely among tree species. This effect may be linked to varying bark thickness and to bark's insulating potential against water loss during the fire. The host's vigor before its death, measured from growth rings of the last 10 years, had a positive effect on cerambycid emergence, but no effect on scolytids.

The economic value of four forest ecosystems, fire-damaged forests, cut blocks, and several park management features was estimated for backcountry recreationists, primarily canoeists, in Nopiming Provincial Park in eastern Manitoba. The analysis was conducted using the travel cost random utility model. It revealed that the forest ecosystems associated with jack pine (Pinusbanksiana Lamb.) and white spruce (Piceaglauca (Moench) Voss) were valued by recreationists. On the other hand, the analysis predicted that recreationists would pay to avoid black spruce (Piceamariana (Mill.) BSP) and aspen (Populustremuloides Michx.) ecosystems, fire-damaged forests, portages, and cottages. The results provide weak statistical evidence that cut blocks that are not in the line of site of recreationists provide positive benefits. While park management variables play a role in determining recreation values, the ages and types of forests located at recreation sites are more important. These findings support a major role for fire in determining recreation economic benefit flows from forests in the Canadian Shield.
