Freshly lifted seedlings and 21-year-old trees of loblolly pine were wound-inoculated with Leptographium species recovered from the soil and/or roots of trees with loblolly decline symptoms in central Alabama. Seedlings inoculated with L. procerum in the greenhouse produced significantly fewer root initials and a smaller root mass than control seedlings. Vertical lesions produced in seedlings by L. serpens and L. terebrantis were significantly longer than in controls. Lesions produced in mature trees by L. serpens and L. lundbergii were significantly longer than in controls. Of the fungi tested, L. serpens, L. terebrantis, and L. lundbergii were the most aggressive and may pose the greatest threat to loblolly pines.

Pine Decline

Abstract Pine decline is an emerging forest health issue in the southeastern United States. Observations suggest pine decline is caused by environmental stress arising from competition, weather, insects and fungi, anthropogenic disturbances, and previous management. The problem is most severe for loblolly pine on sites that historically supported longleaf pine, are highly eroded, or are not managed. The purposes of this technical note are (1) to describe the symptomology and extent of pine decline in the southeastern United States; (2) to describe its connection with root disease, resource stress, and silviculture; and (3) to summarize the consensus opinion of scientists and land managers during a workshop sponsored by the US Army Strategic Environmental Research and Development Program regarding the scope of this syndrome and the best research avenues to counter its potential effect on the sustainability of southern pine forests.

Restoration Strategies

Trees and forests have always played a significant role in the cultural and spiritual lives of societies. Understanding the cultural importance of tree species is necessary to develop socially acceptable forest management and restoration strategies. White pine (Pinus strobus L.) used to be abundant in northeastern North America, including on the ancestral territory of the Kitcisakik Algonquin community (western Quebec, Canada). The community is calling for restoration and sustainable management of white pine on their ancestral territory. As a first step towards this goal, key informant interviews were used to document the cultural importance of white pine to the Kitcisakik community. White pine was perceived as an important component of traditional life, providing several goods and services. White pine is featured in legends, is used as a medicine, provides habitat for flagship wildlife species, and is a prominent part of cultural landscapes. White pine is a cultural keystone species for the Kitcisakik Algonquin community. Local people point to extensive logging as the reason behind white pine decline on the ancestral territory. They suggest that mixed plantations should be used in a culturally adapted restoration strategy.
