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. Various models, including niche models transfer response functions, have been employed guide AM efforts. Each these advantages limitations, necessitating comprehensive understanding their rationale constraints for further development improvement. our review, we aimed define elucidate scenarios which becomes critical necessity context change. Furthermore, provided overview commonly used functions realm AM.

Active management is often mentioned but rarely defined in current policies and strategies for native forests of temperate Australia. Lack clarity about active could mean that to support forest health human involvement with are not fit purpose.

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.

Adaptive silviculture for climate change in the Great Lakes- St. Lawrence Forest Region of Canada: Background and design of a long-term experiment

The Forestry Chronicle, Год журнала: 2024, Номер 100(2), С. 155 - 164

Опубликована: Май 29, 2024

We present the implementation of Adaptive Silviculture for Climate Change (ASCC) initiative at Petawawa Research Forest (PRF) in Ontario, Canada. The study addresses urgent need adaptive forest management strategies response to climate change by examining silvicultural treatments aimed mitigating its impacts on ecosystems. It complex interplay between projections, regional characteristics, and practices pine dominated forests Great Lakes-St. Lawrence region Canada, underscoring importance approaches sustaining outline design objectives five distinct treatments—control, business-as-usual, resistance, resilience, transition—implemented over 4 replicate blocks a 212-ha area PRF. provide detailed descriptions each treatment’s objectives, desired future conditions, strategies. conclude summarizing planned research efforts, including seedling survival assessments, phenological monitoring, measuring treatment impact fuel loads. By addressing challenges opportunities as part an international network, this will contribute deeper understanding ecosystem responses inform sustainable management.

A practical framework for applied forestry assisted migration

Frontiers in Forests and Global Change, Год журнала: 2024, Номер 7

Опубликована: Окт. 30, 2024

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. We developed practical (the Framework) provide structured approach ensure most considerations best science utilized by wanting implement base. The Framework incorporates multiple factors application four sequential phases: assessment analysis, climate-based plant material selection, procurement deployment, documentation monitoring. was tested developing plan Superior National Forest, Minnesota (MN), lessons learned from development specific were used revise improve suitability across all lands.

Abstract This field note presents an early example of a forest climate adaptation tree planting project incorporating assisted migration in southern New England which is valuable providing lessons that can inform future work this region and elsewhere. effort notable for moving forward through the implementation monitoring stages during period when many similar projects encountered barriers.

Forest assisted migration and adaptation plantings in the Northeastern US: perspectives and applications from early adopters

Threats to the future function of forested ecosystems and stability ecosystem service provisioning due global change have motivated climate-adaptive forest management strategies that include various forms tree planting termed “adaptation plantings”. Despite emergence these strategies, less is known as how foresters other natural resource managers perceive or are engaged with adaptation plantings like assisted migration (FAM). This knowledge gap most pronounced in regions New England North Central US (hereafter, Northeastern US) where common but expected be an important tool for adaptation. To address this, we surveyed 33 this region actively climate (i.e., early adopters practice) assess currently being pursued against perceived barriers, opportunities, potential engagement strategy. Survey respondents overwhelmingly (93.5%) forecast increases use their work region, attributed increased awareness, acceptance, interest practice. Respondents expressed notable related diversification types FAM (e.g., population expansion range expansion), hesitancy engage more contentious afforestation linked long-distance translocation exotic species migration). Although examples local enrichment non-FAM) proliferate, nineteen top twenty genera planted contain at least one example study region. The barriers reported were themed 1) biotic abiotic, 2) information material, 3) policy, social, economic factors.

With the increase in global temperature, change situation dominated by climate warming is becoming more and serious. Climate will cause differences suitable areas of species different periods. Ginkgo biloba L., a rare endangered wild plant protected at national level China, oldest relict world. Because severe change, only China’s has been preserved, yet population facing extinction risk. rich ornamental value, application economic medicinal value ecological value. Not can it produce benefits, but also huge social benefits. Based on data sample distribution, bioclimatic variables soil variables, this paper uses MaxEnt model to simulate area under current future scenarios, analyzes changes potential through ArcGIS 10.6. The results are as follows: (1) simulated AUC > 0.9, showing that simulation have high accuracy; (2) min temperature coldest month, precipitation wettest elevation, seasonality main environmental affecting area; (3) predicted expand future, covering most south some northeast regions, moderate conducive for growth biloba; (4) distribution center move northeast.
