In the face of anthropogenic climate change, forest and tree populations must adapt, migrate, or extirpation. Assisted migration (AM) has emerged as a promising forestry strategy to mitigate impacts yet its role in evolutionary ecological processes remains unclear.

A practical framework for applied forestry assisted migration

Frontiers in Forests and Global Change, Journal Year: 2024, Volume and Issue: 7

Recent and projected changes in climate over this century pose an unprecedented threat to the health, diversity, productivity of forest ecosystems. Forests have migrated adapted long-term thousands millions years; however, natural migration rates adaptive responses tree populations cannot match rapid pace current change. Consequently, more climate-informed approaches reforestation are needed as strategies using local seed sources may no longer be adequate meet management objectives. Assisted is a change adaptation technique that can help maintain ecosystem services economic value forests provide. Forestry assisted (FAM) focusses on movement widespread, commercially, or ecologically important species within just beyond their ranges way health face Although forestry community recognizes FAM tool, guidance for planning implementation lacking framework provides prove useful land managers with limited time resources available who want undertake FAM.

Despite the need for climate change mitigation and altered forest management practices, little is known about impacts of silvicultural practices such as partial-cuts clear-cuts on ecosystem carbon (C) dynamics. Specifically, effect these two overstory treatments C pools other than aboveground biomass trees remains poorly understood. Here, stocks were estimated a northern temperate mixed located in eastern Québec, Canada, five years after clear-cutting partial-cutting, either with or without brushing treatment to control competing vegetation. The vegetation (trees, saplings, understory), litter woody debris (coarse, small, fine), well roots (diameter ≤ 1.5 cm) was evaluated. Additionally, soil up depth 35 cm mineral assessed.

Climate change increases air and soil temperatures the frequency of extreme weather events such as high temperatures, droughts, flooding. These changes negatively impact forest ecosystems provision ecosystem services timber supply carbon sequestration. Fine roots associated mycorrhizae play an essential role in functioning because they absorb water nutrients from owing to their short lifespan, significant amounts are transferred through them into soil. Here, we reviewed existing literature on responses tree fine root systems increasing temperature availability waterlogging. We also discussed how negative environmental can be mitigated management operations by selecting species provenances, growing mixed stands, carrying out continuous-cover forestry, avoiding rutting compaction when using vehicles. Our main focus is boreal temperate forests. Knowledge changing conditions different practices, which could used mitigate effects, still very limited requires more research development before introduced practice.
