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.
