ABSTRACT Aim We model and map the climatically suitable habitats migration potential of 326 tree species by combining forest inventories United States, Canada to a lesser extent, Mexico, with goal providing continental perspective ranges facilitate better stewardship under changing climate. Location Canada, Mexico. Major Taxa Studied Tree species. Methods use multi‐model ensemble technique assess climatic habitat suitability current future climates, compute colonisation likelihoods simulate end century migration. combine synthesise these outputs provide various products relevant range‐wide assessment Results For species, we maps of: suitability, SSP2‐4.5 SSP5‐8.5 scenarios, combined for century. In addition, synthesis (a) climate topographic statistical range assessments, (b) differences in richness from (c) performance, (d) climate‐topographic variable‐importance groupings (e) disequilibrium trends across genera. A continent‐wide both individual responses showed evidence smaller ranges, projected reduction middle lower mid‐continental regions, an increase southeastern, northeastern, northwestern regions continent. Also, found most eastern were mainly driven moisture, while western strong associations heat moisture. Main Conclusions Our study provides, first time, baseline understanding overall dynamics shifting their entire range, facilitating improved management North American forested ecosystems.

Effects of lag time in forest restoration and management

Forest Ecosystems, Journal Year: 2023, Volume and Issue: 10, P. 100131 - 100131

Published: Jan. 1, 2023

The increased speed of global change and associated high severity disturbances, in conjunction with the increasing suite societal expectations on forests, suggest that timeliness interventions to encourage adaptive capacity ecosystems reduce negative impacts regards provision ecosystem services is increasingly relevant. To address this issue, we expand concept lag time as used ecological discussions into a forest management context. In context, times have earlier starting later ending points can be separated different components. These components include delay till detection, decision making, implementation, followed by are provided at acceptable levels. first three influenced availability information, lack which extend times. Also, lengths not simply additive but interact. For example, treatment preparation due quicker detection lead shorter implementation We highlight benefits addressing various forestry operations. Especially when considering change, our analysis suggests all aspects sector challenged consider how optimize Last, propose such issues need considered any action especially relevant whether best strategy after disturbances or light adopt passive approach let natural processes play out their own active better suited ensure more rapid fitting response facilitate continued services.

A practical framework for applied forestry assisted migration

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

Published: Oct. 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.

Forester interest in, and limitations to, adapting to climate change across the rural-to-urban gradient

Climate Risk Management, Journal Year: 2024, Volume and Issue: 45, P. 100624 - 100624

Published: Jan. 1, 2024

Climate change-related challenges faced by forest managers are ecological, economic, and social in nature. While several past assessments have looked at the climate-related perceptions needs of foresters working rural contexts, urban not often included these assessments. Examining foresters' risk perceptions, adaptation interests intentions, need for information/support contexts side-by-side reveals unique opportunities learning across rural-to-urban gradient. Through two surveys targeting both foresters, we identified key that support climate-adaptive management. Our analysis shows many seeking to maintain current conditions or restore following a disruption change, though some see value transitioning forests be more resistant resilient future climates. We also show difference confidence between when it comes addressing climate change through specific strategies. Based on our findings, propose facilitated This would allow learn from topics such as establishment maintenance long-term, large, ecologically complex forested areas within cities. Rural could gain insights their counterparts planting strategies other approaches common settings but novel settings, including stock sourcing species selection. To better enable implement strategies, suggest: (1) facilitating gradient, (2) public engagement trainings (3) workforce development programing, (4) programs limit financial landowners, municipalities face applying lands.

Potential migration pathways of broadleaved trees across the receding boreal biome under future climate change

Abstract Climate change has triggered poleward expansions in the distributions of various taxonomic groups, including tree species. Given ecological significance trees as keystone species forests and their socio‐economic importance, projecting potential future is crucial for devising effective adaptation strategies both biomass production biodiversity conservation forest ecosystems. Here, we fitted physiographically informed habitat suitability models (HSMs) at 50‐m resolution across Sweden (55–68° N) to estimate northward expansion seven broadleaved within leading‐edge Europe under different climate scenarios time periods. Overall, observed that minimum temperature was most variable comprehending spatial distribution cold limits. Our HSMs projected a complex range pattern 2100, with individualistic differences among However, frequent rather surprising along east coast followed by narrow migration pathways larger valleys towards edaphically suitable areas north‐west, where studied were predicted expand.

Forest-clearing to create early-successional habitats: Questionable benefits, significant costs

Frontiers in Forests and Global Change, Journal Year: 2023, Volume and Issue: 5

Published: Jan. 9, 2023

A campaign is underway to clear established forests and expand early-successional habitats—also called young forest, pre-forest, early seral, or open habitats—with the intention of benefitting specific species. Coordinated by federal state wildlife agencies, funded with public money, land managers work closely hunting forestry interests, conservation organizations, trusts, private landowners toward this goal. While forest-clearing has become a major focus in Northeast Upper Great Lakes regions U.S., far less attention given protecting recovering old-forest ecosystems, dominant cover these before European settlement. Herein we provide discussion habitat programs policies terms their origins, context historical baselines, respect species’ ranges abundance, as they relate carbon accumulation ecosystem integrity. Taken together, face urgent global crises climate, biodiversity, human health, conclude that forest management must be reevaluated balance prioritization funding strong lasting protection for old-growth mature forests, and, going forward, ensure more robust, unbiased, ongoing monitoring evaluation.
