Eastern Silviculture & Forest Ecology

Benefits of Mixedwood Management: Reduced Spruce Budworm Impacts in Acadian Spruce-Fir Hardwood Forests

Open to view video.

Open to view video. Spruce-fir stands with higher hardwood content sustain lower defoliation, growth reduction, and mortality during spruce budworm outbreaks. We are testing the mechanism, whether higher parasitism and/or greater larval dispersal losses, in an outbreak that began in 2013 near Amqui, Quebec. Optimum hardwood level depends on severity of budworm attack. Presented by David MacLean, University of New Brunswick

Maintaining the Softwood Component in Yellow Birch-Conifer Stands of Eastern Canada: A Great Challenge

Open to view video.

Open to view video. Managing mixed productions of hardwoods and softwoods is challenging because of the diversity of species and their ecological characteristics to consider when designing silvicultural prescriptions. We will present results of two experiments showing that despite important silvicultural efforts, regenerating conifers remains challenging in these rich sites, especially for red spruce. Presented by Patricia Raymond, Quebec Ministry of Forest, Wildlife and Parks

Putting the ‘Mixed’ in Mixedwoods: Silvicultural Approaches to Shortleaf Pine Regeneration in Pine-Oak Forests

Open to view video.

Open to view video. In the Missouri Ozarks, managing shortleaf pine-oak mixedwoods is challenging due to shortleaf pine regeneration failures. Shortleaf pine may be regenerated from seed following regeneration harvests, by releasing advance reproduction with regeneration harvests, or through artificial regeneration. We present results from several studies to discuss potential success of these approaches. Presented by Benjamin Knapp, University of Missouri

Northern Silviculture & Forest Ecology

Forest Understory Vegetation Exhibits Increased Diversity and Structural Variation Under Residue Removals

Open to view video.

Open to view video. Logging residue derived nutrients can influence vegetation community patterns and long-term site productivity. We investigated vegetation characteristics across a commercial rotation in Upper Michigan. Results indicate that residues can increase understory species diversity and variance in species proportional representation, and that these patterns may be attributed to increased site disturbance. Presented by Michael Premer, Michigan Technological University

Southern Silviculture & Forest Ecology

Opportunities and Benefits of Using Biosolids and Compost for Fast Growing Plantations

Open to view video.

Open to view video. Productive eucalypt, pine, and cypress plantations typically require site amendments. As demonstrated in Florida, readily available biosolids and compost have potential as alternatives to inorganic fertilizers. The cost-effectiveness of these organic amendments, though, depends on a number of factors. Use of biosolids and compost has a number of environmental benefits. Presented by Donald Rockwood, University of Florida

Managing Multi-Aged Longleaf Pine Forests: Overstory and Regeneration Response to Harvest Treatment

Open to view video.

Open to view video. Three selection-based silvicultural approaches were implemented in multi-aged longleaf pine forests. Five years after harvest overstory tree response was highly variable with no significant plot level effects; response was spatially associated with local crown competition. Seedling growth was not different between treatments, and seedling recruitment was low in all treatments. Presented by Steve Jack, Jones Ecological Research Center
