Baseline data on the boreal jack pine associated chanterelle (Cantharellus cibarius) and pine mushrooms (Tricholoma magnivelare) in the Boreal Plain Ecozone of Saskatchewan was collected in five ecosites of productive mushroom areas. It investigated hourly weather parameters correlated with daily purchase volumes over four years; yield data over five years; varying age/ tree density/species for presence of mushrooms in over 100 stands. All plots fell within the lichen jP ecosite with an overstory entirely of jack pine. The understory was dominated by reindeer lichen, bearberry and blueberry. Plots were well- to rapidly drained, subxeric to submesic, with low nutrient regime. Both chanterelle and pine mushrooms were present in jack pine stands of < 20 years age with greatest occurrence in pure jack pine stands of 41–60 years in moderately open A-B canopy density. Weekly purchase data correlated with environmental parameters. Growing Degree Days (Base Temperature 5oC) + soil temperature (minimum 500 ± 70 GDD), + either soil moisture or precipitation (cumulative 50–100 mm) provided the highest regression value with chanterelle yield 6–13 weeks prior to first appearance. Five year total chanterelle yield from this region averaged 7100 kg/yr. Chanterelle cap diameter was a good predictor of fresh weight and proxy for yield. Pine mushroom was < 10% of chanterelle yield, averaging 1.72 kg/ha over four years based on 5 days picking. With future climate predictions of warmer and moister conditions, timing of fruiting body appearance is anticipated to advance.

Multiple regression equations have been developed to predict yield from young red pine and jack pine plantations. Data from 446 sample plots representing young red pine and jack pine stands located on the south shore of the St. Lawrence River between Quebec and Montreal were analysed. The red pine plantation yielded more than the jack pine. However, in plantation both species yield more than in natural stands. Taking into account the age and spacing of the sampled plantations, the equation obtained can provide information on yield of red pine and jack pine stands the maximum spacing of which is 3 × 3 m, up to the age of 45 and 35 years respectively. The equations will allow the construction of preliminary yield tables for both species.

AbstractParasitoid populations were sampled before, and for 4 years following, an aerial application of the insecticide phosphamidon to control a sawfly outbreak. Adult parasitoid mortality was high because of spraying, but a reservoir of parasitoids in host cocoons remained to repopulate the treated areas. In moister sites the number of species decreased and their relative abundance changed, but moderate numbers of parasitoids remained 4 years after spraying. In a dry site with little ground vegetation, none of the species present before spraying remained by the fourth year.

Insect Attack

The forests of northern Ontario are damaged frequently by strong winds that develop along cold fronts. Deterioration of spruce (Picea spp.) and jack pine (Pinusbanksiana Lamb.) saw timber because of wood-boring insects was studied in an extensive area of blowdown between 1969 and 1972. Sawyer beetles (Monochamus spp.) were the most important agents of degrade, but a surprising amount of damage was caused in spruce by Tetropium spp. Broken trees fared worst, but all uprooted trees were heavily attacked by 2 years after the storm. Milling studies showed about a 10% loss in all material combined 1 year after the storm, with the loss in general more than doubling in the 2nd year. The greatest loss occurred in white spruce (Piceaglauca (Moench) Voss), which was of greater original value than jack pine. Trees left standing were not attacked by emerging beetles but were subject to windthrow by relatively light winds. Salvage operations, when desirable, should begin as soon as possible after a blowdown and all stems, including those left standing, should be harvested at once.

Burn Depth

Increased fire frequency, extent and severity are expected to strongly affect the structure and function of boreal forest ecosystems. In this study, we examined 213 plots in boreal forests dominated by black spruce (Picea mariana) or jack pine (Pinus banksiana) of the Northwest Territories, Canada, after an unprecedentedly large area burned in 2014. Large fire size is associated with high fire intensity and severity, which would manifest as areas with deep burning of the soil organic layer (SOL). Our primary objectives were to estimate burn depth in these fires and then to characterise landscapes vulnerable to deep burning throughout this region. Here we quantify burn depth in black spruce stands using the position of adventitious roots within the soil column, and in jack pine stands using measurements of burned and unburned SOL depths. Using these estimates, we then evaluate how burn depth and the proportion of SOL combusted varies among forest type, ecozone, plot-level moisture and stand density. Our results suggest that most of the SOL was combusted in jack pine stands regardless of plot moisture class, but that black spruce forests experience complete combustion of the SOL only in dry and moderately well-drained landscape positions. The models and calibrations we present in this study should allow future research to more accurately estimate burn depth in Canadian boreal forests.
