< Retour Assisted migration trials: early response AD 9b Hub: All Year: 2022-2025 Jacob Ravn, PhD After collaborating with the RA to oversee the implementation of each trial, project AD 9a, a PhD student will have for objective to monitor of the early response at each site. They will compare the performance of different genotypes and species within and across sites. This comparison will allow us to (i) estimate the adaptive capacity of cold-adapted genotypes to increasing temperatures, and (ii) identify genotypes from warmer areas well suited for assisted migration at higher latitudes. Outcome (AD.9b): An analysis of the survival and early growth success of the newly established seedlings.

< Retour Integration of climate drivers into growth modelling (AN3b) AN 3b Hub: Black Brook, NB; Acadia, NB; Nova Scotia Year: 2021-2023 Jamie Ring, MSc Diversifying the species composition and structure of forest stands is often proposed as a solution to increase the resilience and resistance of forests to stressors. Yet, most existing models to predict forest growth and stand dynamics in Canada have been developed for even-aged, single-species stands. A Msc student, focusing on the Acadian forest sites, will have for objective to integrate climate drivers into the model framework of existing forest growth and yield models from the Prognosis/FVS family, improving our capacity to anticipate the effects of interactions between climate, stand composition and structure on growth. Model predictions will be verified using stand structure and growth rate combinations highlighted through the big data analysis undertaken in OB.7. Outcome: New model formulations for mixed-species, multi-cohort stands available via open source platforms to allow use and testing at additional sites.

< Retour Thinning as a tool to increase resistance to stressors AN 6a Hub: Quesnel, BC Year: 2022-2024 Sergio Alonso Sanchez, MSc While targeted thinning of a productive stand can increase the vigour for the remaining stems, and thus resistance to stressors such as drought, insects and disease, thinning operations are not without inherent risk from windthrow, for example, and they may not be commercially viable. Within BC, stands are expected to become more impacted by drought and other disturbances into the future and, as a result, detailed stand-level studies are needed to determine when and what type of thinning operations should be implemented. Working in the QN Hub, Sergio will have the objective to examine how thinning scenarios can be tailored to reduce the overall risk of losses over a full rotation. He will use a cost-benefits approach and consider operational realities such as harvest level, distribution of stem removal, harvesting technologies and road access. Outcome: Recommendations on how, when and where thinning offers commercially viable solution to reducing risk, despite uncertainties in climatic conditions.

< Retour Characterization of regeneration failure in the Canadian boreal forest using satellite imagery and airborne laser scanning data OB 7 Hub: RM, LSJ, MM Year: 2024 - 2028 Shaya (Fatemah) Gholami, PhD Boreal forests constitute the largest carbon reservoir globally, providing a wide array of ecosystem services and serving as an essential timber source for societal needs. Natural and anthropogenic disturbances can profoundly alter the structure and composition of these ecosystems. While the complex interactions between climate change, the frequency, severity, and extent of these disturbances, and the forest regeneration trajectories have received considerable attention in recent decades, their exact consequences remain poorly understood. The objective of this project is to characterize and assess the magnitude of regeneration failures following clearcutting and forest fires at different locations in the Eastern boreal forest of Canada. By combining satellite images from various sensors with airborne laser scanning (ALS) data, this project will bring new insights into post-disturbance regeneration dynamics and identify factors responsible for the variability in the success of regeneration establishment. The results will help quantify the impact of regeneration failures on timber yield and the provision of ecosystem services, and allow for the spatially explicit identification of areas that should be prioritized for targeted silvicultural actions.

< Retour Revisiting existing trials AD 1a Hub: All Year: 2023-2025 Ethan Ramsfield A wealth of past trials exists in Canada on the establishment and growth of species across a wide range of environmental conditions. In some cases, these trials have been actively maintained (including the NEBIE Plot Network in Ontario, a network of 120 2-hectare experimental units located across 4 fire regimes) while others have not been re-measured for significant periods of time. Our objective will be to study the long-term growth responses of trees to various adaptive strategies that have been tested in past trials. After reviewing existing trials, a PhD project will conduct a highly targeted re-measurement program to gather new information where necessary, so that a comprehensive dataset of past trials can be analysed offering key insights into the future responses to adaptive measures proposed in Silva21. Outcome: Key lessons to inform Silva21 projects on the likely impact and success of silvicultural strategies. Ethan Ramsfield, M.Sc.

< Retour Rainfall exclusion experiment: the effect of thinning AD 3c Hub: Black Brook, NB; Nova Scotia, NS Year: 2023-2025 Chloe Larstone Hunt, MSc In addition to the risk of catastrophic losses from fire, droughts may also induce significant losses of wood fibre production. Precommercial thinning is proposed as a promising treatment to reduce water uptake at the site level, and thus make young plantations more resistant to drought. To test the efficiency of this treatment under extreme conditions, we will install a rainfall exclusion structure in two white spruce plantations in the BB and NS hubs, each consisting of a range of open-pollinated families. An MSc student will then have for objective to study the survival and radial growth response trees to a range of thinning intensities. Outcome (AD.3c): recommendations on what thinning intensity to prescribe to increase resistance to drought while limiting the loss of productivity due to a lower site occupancy.

< Retour Stem vigour and growth of tolerant hardwoods AN 4 Hub: Haliburton, ON Year: 2022-2024 Guillaume Moreau, PDF Key to ensure the growth response of tolerant hardwood stands to partial cut is to carefully select the unacceptable growing stock, and thus leave the most vigorous trees standing. However, it remains unclear how vigour evolves over time, and whether the stem defect criteria used in operational tree marking guidelines are good predictors of tree vigour. A PDF will take advantage of unique historic longitudinal datasets available at the HA and NS Hub sites with the objective to determine how various types of defects affect tree growth and stand dynamics over time. The PDF will first identify the factors (including species, defect types and climatic stress events, etc.) leading to a loss of vigour over time, and then devise partial cutting guidelines to maximise resilience and growth. Outcome: A set of trees marking guidelines to promote stand vigour in northern hardwoods.
