Commercially Important

Neodiprion swainei, a defoliating sawfly specific to jack pine, has destroyed thousands of acres of commercially important jack-pine forests in recent years. This sawfly can kill trees within 4 years of the start of a population increase. Outbreaks are usually found in foci in poorer jack-pine sites on outwash plains. Tree mortality occurs after complete defoliation of the previous years' foliage, combined with severe defoliation of the current year's foliage. Tree mortality starts in the first year after particularly severe defoliation and may be cumulative to 5 years; thus, detection of the insect in a stand should warrant increased watchfulness.Outbreaks may follow at intervals of about 8 years. Hazard areas for Quebec and Ontario are defined.

Abstract Because of the long time periods involved, empirical data on the effects of preceding stand age on nutrient availability in the succeeding stand are scarce. We took advantage of a unique management situation in the jack pine forests of northern Lower Michigan to assess the effects of preceding stand age (24‐76 years) on postharvest soil nutrient availability. We found that potentially mineralizable nitrogen (N) and extractable phosphorus (P) increased with increasing age of the preceding stand. In contrast, we observed no response of total organic carbon (C) and N or extractable base cations to preceding stand age. Together, our results demonstrate that harvesting these forests at younger ages results in decreased availability of N and P immediately following harvest.
