Protecting Biological Diversity: A Major Challenge For Minnesota Forestry In The 1990s, David C. Zumeta

Journal of the Minnesota Academy of Science

One of the most significant challenges to Minnesota forestry in the 1990s will be responding to growing public concern about relationships between forestry in Minnesota and global and national environmental issues (e.g., protecting biological diversity, tropical deforestation). Influential citizens and public interest groups are asking penetrating questions about the effects of forest management and timber harvesting on biological diversity, and about parallels between tropical deforestation and timber harvesting in Minnesota.

This article examines some of the relationships between Minnesota forestry and biological diversity. It also describes what is being done, and what needs to be done, to protect biological diversity. …

A Study Of The Northern Upland Forest On The Islands Of The Whitefish Lake Chain, Minnesota, Roy K. Blowers

Journal of the Minnesota Academy of Science

During an investigation of the area of the Whitefish Lakes, it was noted that two definite types of forest communities existed, a conifer forest and a hardwood forest. It was also noted that each type appeared on different parent soil materials. The problem was actually divided into four parts as follows: How well did the vegetation and the parent material correlate? What was the plant succession in the area? How was the plant succession affected by the parent material? And, how was the resulting soil affected by the vegetation?

It was decided that a forest study of islands would give …

The Interrelationships Of Bark Beetles And Blue-Staining Fungi In Felled Norway Pine Timber, J. G. Leach, L. W. Orr, Clyde Christensen

Journal of the Minnesota Academy of Science

A study of two species of bark beetle (lps pini Say and I. grandicollis Eichh.) and the fungi associated with them has been made as the first part of a general investigation of the interrelations of insects and fungi in the deterioration of felled logs of Norway pine.
