Special Issue Information

Dear Colleagues,

Forests are highly dynamic, especially at younger ages. Understanding the impacts of silvicultural treatments/interventions on regeneration, growth and yield, forest carbon, and other ecosystem functions and linking early performance to long-term stand dynamics are, therefore, critical to management decisions targeting the provision of multiple benefits to forest ecosystems. Quantitative effects of silvicultural treatments/interventions and linkages between regeneration performance and long-term growth and yield vary with species and site conditions, as well as with disturbances such as pests and changing climate. Traditionally, short-term effects and long-term dynamics are assessed separately at different times and by different researchers, resulting in a lack of information on the quantitative connections between regeneration performance and long-term growth and yield. This has limited our ability to quantitatively evaluate management decisions, forest management planning, and wood supply analysis. This Special Issue will be transdisciplinary and is intended to bridge silvicultural treatments, regeneration performance, intermediate interventions, and long-term growth and yield using field observations, management records, modelling, and data synthesis for understanding and establishing quantitative links between short-term treatment effects and long-term stand dynamics.

Potential topics include, but are not limited to, the following:

  • Quantitative effects of silvicultural treatments/interventions;
  • Linking regeneration to growth and yield;
  • Competition and density management;
  • Short-term treatment effects and long-term stand dynamics;
  • Quantitative tools to measure, model and predict.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Regenerating conifers after harvest through planting and postharvest broadcast application of herbicide is effective in ensuring the survival and growth of seedlings, but faces challenges in meeting broad social and ecological objectives of forest management. This study reports the effectiveness of alternative options in regenerating jack pine (Pinus banksiana Lamb.), 21 years after harvest of trembling aspen (Populus tremuloides Michx.)-dominated boreal mixedwood stands. The treatment options included (i) preharvest spray—aerial broadcast spray prior to harvest, (ii) postharvest partial spray—ground herbicide application in strips, (iii) partial harvest in strips, (iv) postharvest aerial broadcast, and (v) uncut reference. Twenty-one years after treatments, the four harvest treatments were similar in overstory density (4000 stems/ha) and basal area (BA, 20 m2/ha), but differed in composition and structure. The preharvest spray had an intimate mixture of aspen and jack pine (22% and 57% by BA, respectively), compared to spatial mosaics of aspen and pine corridors in the partial spray (36% and 41%), and aspen and maple corridors in the partial cut (21% and 31%). While the postharvest broadcast was pine-dominated (74% by BA) as expected, uncut and partial cut were similar in pine composition (10% by BA), which is inadequate for aspen and pine mixedwood stands. The early positive effects of preharvest spray and partial harvest on understory species abundance and diversity became neutral 21 years postharvest. The implications of these findings are discussed with respect to stand conditions before harvest, postharvest regeneration dynamics, and treatment objectives for the renewal of trembling aspen and jack pine mixedwood stands after harvest.

As forest managers increasingly seek to develop and maintain mixedwood forests, more information is required on the potential facilitative and competitive interactions between tree species. We present data from a broadleaf thinning study established in a mixedwood stand in Central British Columbia, Canada, to examine how residual trembling aspen and paper birch competitively affect spruce growth after thinning but may also concurrently protect spruce from attack by the white pine weevil. Tree-level data collected at a stand age of 36 years, 19 years after broadleaf trees were thinned, show that spruce height and diameter growth declined with broadleaf competition, particularly from taller trees, resulting in a competition-related reduction in stand-level spruce volume yields. The fastest spruce growth occurred in treatments where all broadleaf trees were removed, but complete broadleaf removal also resulted in higher rates of weevil attack on spruce, which also caused height and diameter growth reductions. Our results suggest that maintaining a density of approximately 500 broadleaf trees per hectare may achieve a stand condition that balances spruce growth reductions from competitive interactions with broadleaf trees while providing some protection from white pine weevil attacks.
