Hardwood forests of the Mid-Atlantic region have a multitude of values. They provide timber for furniture, paper, and other products, habitats for wildlife, water for homes and industry, and opportunities for outdoor recreation activities of many types. They dominate much of our landscape, serve as reservoirs of biological diversity, alter climate, and affect our lives in many ways that we are only beginning to understand.

Many city dwellers hold very strong personal ties to urban trees and forests, with some attachments approaching a spiritual involvement. Ties between people and trees are associated with traditions, symbolism, and the need to "get involved" at the local level to sustain or enhance the environment for present and future generations. Urban forestry programs that aim to improve quality of life in urban areas will be most effective if urbanites learn about the basic biological needs of trees. At the same time managers and planners must learn about the many psychological, social, and cultural...

Including utility poles in red pine management regimes leads to distinctly different management recommendations. Where utility pole markets exist, managing for poles will maximize net returns. To do so, plantations should be maintained above 110 ft2/ac, higher than usually recommended. In Michigan's northern lower peninsula, approximately 195,000 ac of established stands were suitable for utility pole management in 1980. Landowners can increase the soil expectation value (4% discount rate) on their investment from $4.00/ac to $104/ac by managing for poles along with pulpwood and sawtimber...

Describes a trap design to use in collecting larval frass or head capsules for estimating densities of aboveground arthropods. The trap is light, compact, durable, and easily constructed from common inexpensive items.

Presents the soil and tree wood tissue properties (mostly chemical) of the plots that were remeasured and sampled for a study of the relation between forest condition and wet sulfate deposition along the Lake States acidic deposition gradient.

Discusses recent Minnesota forest industry trends; production and receipts of pulpwood, saw logs and veneer logs; and production of other timber products in 1988. Reports on logging residue, wood and bark residue generated at primary wood-using mills, and disposition of mill residues.
