Improving the Composition of Beech-Dominated Northern Hardwood Understories in Northern Maine

Problem Addressed: American beech dominance following natural disturbance and shelterwood and selection harvesting

Goal(s)/Objective(s): Identify glyphosate rate and surfactant concentration that produce maximum beech control and minimal injury to desirable hardwood species

Key Findings: Dominant hardwood species differed substantially in their susceptibility to the treatments in the following decreasing order: beech, striped maple, yellow birch, red maple, sugar maple.

Recommendation: this relatively low-cost and effective treatment can substantially improve the understory composition of northern hardwood stands

Arboreal arthropod associations with epiphytes following gap harvesting in the Acadian forest of Maine

Problem Addressed: Sensitivity of Collembola, Araneae, and Diptera to forest management.

Goal(s)/Objective(s): Further examination of gap harvesting on Collembola and their associations with epiphytes and arthropods.

Key Findings: The correlation among bryophytes, Collembola (springtails) and Araneae (spiders) suggest a potential trophic interaction where arboreal spiders, during early developmental stages, were dependent upon availability of Collembolan prey

Recommendation: Dipterans may be good candidates as indicators of forest management impacts on the larger arthropod community

Early stand production of hybrid poplar and white spruce in mixed and monospecific plantations in eastern Maine

Problem Addressed: Potential benefits of increasing intensity of silvicultural practices on Maine's forestlands.

Goal(s)/Objective(s): Compare early growth of pure white spruce, pure hybrid poplar, and white spruce-hybrid poplar mixed-species plantations on a typical reforestation site in eastern Maine.

Key Findings: Three years post planting, hybrid poplar height and ground line diameter growth rates began to diverge among clones; by 6 years, the Populus nigra x Populus maximowiczii clone clearly outperformed three other Populus spp. clones both in pure stands and in mixtures with white spruce. In mixture, yield of white spruce declined as yield of hybrid poplar increased.

Recommendation: Forest management in northeastern North America could benefit from increasing intensities of silviculture and establishing more plantations.

Influence of management intensity on the productivity of early successional Acadian stands in eastern Maine

Problem Addressed: Response of early successional stands to management

Goal(s)/Objective(s): Document response of early successional stands to management inputs designed to shift species composition

Key Findings: After 7 years, yields of mixedwood treatments were greater than conifer release treatments; yields of hardwood thinning treatments were similar to the untreated control, but with lower densities.

Recommendation: Early successional stands can be effectively managed during early stand development to improve growth and the longer term composition

Development and evaluation of aboveground small tree biomass models for naturally regenerated and planted species in eastern Maine, U.S.A.

Problem Addressed: Models for small tree biomass estimates in northeastern North America

Goal(s)/Objective(s): Evaluate additive aboveground component and biomass models for five naturally regenerated hardwood species.

Key Findings: Small tree biomass models currently used to predict woody biomass substantially underestimated biomass at the study site.

Recommendation: Current FAS models may be inadequate for providing reliable sapling biomass estimates in Maine, and new techniques should be developed.

Efficiency of alternative forest inventory methods in partially harvested stands

Problem Addressed: Which inventory methods are best given the distinct spatial and structural heterogeneity in Maine forestlands.

Goal(s)/Objective(s): Compare horizontal point, fixed area, and horizontal line measurement methods in partially harvested stands across northern and central Maine.

Key Findings: Horizontal line sampling proved to be a viable method in post-partial harvest stand conditions.

Recommendation: There are trade-offs between precision and time costs involved in measurement methods under a range of heterogeneous stand conditions.

Effects of intensive forest management on stand and landscape characteristics in northern New Brunswick, Canada (1945–2027)

Problem Addressed: Landscape patterns and changes caused by harvesting and silviculture

Goal(s)/Objective(s): Evaluation of historical and future changes in species composition, age classes, and patch characteristics between 1945, 2002, and projections to 2027

Key Findings: Strong cumulative effect of forest management on landscape patterns, especially the socially mandated drive for smaller clearcuts resulting in the loss of large patches

Long-term response of spruce–fir stands to herbicide and precommercial thinning: observed and projected growth, yield, and financial returns in central Maine, USA

Problem Addressed: Herbicide application, Precommercial thinning

Goal(s)/Objective(s): Long-term growth and yield responses to controlled PCT and herbicide experiments

Key Findings: Early investments in herbicide and PCT may lead to good financial returns
