Abstract Purpose of Review Carbon sequestration and storage in forest ecosystems is often promoted as a solution for reducing CO 2 concentrations the atmosphere. Yet, our understanding lacking regarding how management strategies affect net removal greenhouse gases contribute to climate change mitigation. Here, we present review carbon stock dynamics, following three that are widely used boreal, temperate tropical forests: extensive management, intensive old-growth conservation. Recent Findings Several studies show specific can improve capacity soil storage. Within these studies, conservation strategy results greater soils than do management. Intensive enhances through afforestation using fast-growing species, mechanical preparation from low moderate intensity N fertilization. Extensive an intermediate compromise storage, between strategies. With respect silvicultural treatments, partial cutting practice increases rates maintains higher compared clear-cuts. Each discussed this showed similar effect on all biomes, although magnitude effects differs mainly terms heterotrophic respiration. Summary To achieve sustainable fulfill industrial demand profitability, gaps must be dealt with scientific knowledge context, integration aforementioned functional zoning approach at landscape scale. We promising guiding such global context.

Abstract There is increasing momentum to implement conservation and management approaches that adapt forests climate change so as sustain ecosystem functions. These range from actions designed increase the resistance of current composition structure negative impacts those transition substantially different characteristics. A component many adaptation will likely include assisted migration future climate‐adapted tree species or genotypes. While forest‐assisted (FAM) has been discussed conceptually examined experimentally for almost a decade, operationalizing FAM (i.e., routine use in forest projects) lags behind acceptance need adaptation. As vulnerability ecosystems increases, may become an integral tool reduce long‐term risks function, despite real perceived barriers its implementation. Here we discuss concept operational‐scale why it remains controversial, not yet widely adopted We present three case studies illustrate how practice can be approached pragmatically within framework acceptance. Finally, path toward advancing wide FAM.

Identifying trade‐offs and opportunities for forest carbon and wildlife using a climate change adaptation lens

Conservation Science and Practice, Год журнала: 2022, Номер 4(4)

Опубликована: Фев. 21, 2022

Abstract On a warming planet, key challenge natural resource managers face is protecting wildlife while mitigating climate change—as through forest carbon storage—to the greatest extent possible. But in some ecosystems, habitat restoration for imperiled species may be incompatible with maximizing storage. For example, promoting early successional conditions does not maximize stand‐level storage, whereas uniformly high stocking or mature name of storage excludes that require open young stands. Here, we briefly review literature regarding and trade‐offs then explore four case studies from Northern Forest region United States. In each case, human activities have largely dampened influence disturbances; restoring emulating these disturbances typically required even when doing so equates to less at stand level. We propose applying adaptation lens can help planners navigate steer away maladaptive practices ultimately reduce adaptive capacity. Instead, critically evaluating consequences management actions on both facilitate landscape‐scale planning supports diversity habitats alongside opportunities invest carbon.

A lack of ecological diversity in forest nurseries limits the achievement of tree-planting objectives in response to global change

BioScience, Год журнала: 2023, Номер 73(8), С. 575 - 586

Опубликована: Июль 31, 2023

Abstract Tree planting is increasingly being adopted as a strategy to address global change, including mitigation, adaptation, and restoration. Although reforestation has long been central forest management, the desired outcomes of traditional emerging tree-planting strategies face barriers linked lack ecological diversity in nurseries. In present article, we outline how insufficient nursery seedlings among species, genotypes, stock types impeded will continue hinder implementation diverse or climate-suitable targets, now into future. To support this, demonstrate disparities seedling inventories, focusing on northern United States. overcome these challenges, recommend avenues for improving policy financing, informational resources training, research monitoring. Absent advances, current production practices fall short ambitious goals proposed restoration change mitigation adaptation.

Disturbance has variable effects on the structural complexity of a temperate forest landscape

Ecological Indicators, Год журнала: 2022, Номер 140, С. 109004 - 109004

The temporal dynamics of forest canopy structure are influenced by disturbances that alter vegetation quantity and distribution. While structural indicators such as leaf area index (LAI), cover, height have been widely studied in the context disturbance, post-disturbance complexity, which summarizes heterogeneity arrangement, poorly understood. With goal advancing conceptual empirical understanding complexity following we synthesized results from three large-scale disturbance manipulation experiments at University Michigan Biological Station (UMBS): 4-year Forest Resilience Threshold Experiment (FoRTE) manipulating levels severity; decade-long Accelerated Succession (FASET), all early successional tree species were stem-girdled within 39 ha same landscape; chronosequences established clear-cut harvesting. We found dependent upon factors: (1) source severity disturbance; (2) spatial scales analysis; (3) measure assessed. Unlike initially decreased response to measures top rugosity did not consistently respond moderate severity. Over multi-decadal timescales, increased a maximum, regardless whether fire occurred time stand establishment, but intervening low-to-moderate regrown century-old forests altered trajectories rugosity. conclude display more nuanced directional than conventional cover indexes. Predicting what conditions modify remains critical characterization inference ecosystem functioning.

Ecological memory and regional context influence performance of adaptation plantings in northeastern US temperate forests

Journal of Applied Ecology, Год журнала: 2021, Номер 59(1), С. 314 - 329

Abstract Species distribution models predict shifts in forest habitat response to warming temperatures associated with climate change, yet tree migration rates lag leading misalignment of current species assemblages future conditions. Forest adaptation strategies have been proposed deliberately adjust composition by planting climate‐suitable species. Practical evaluations plantings are limited, especially the context ecological memory or extreme events. In this study, we examined 3‐year survival and growth climate‐adapted seedling transplants within operational‐scale silvicultural trials across temperate forests northeastern US. Nine were selected for evaluation based on projected importance under change potential functional redundancy currently found these ecosystems. We investigated how type (‘population enrichment’ vs. ‘assisted range expansion’) local site conditions reinforce interference interactions existing vegetation at filtering focused transitioning composition. Our results show performance is (e.g. attributes size), strength competition memory) type, a proxy source distance. These findings consistent regional but modified site‐specific such as browse pressure events, namely drought spring frost Synthesis applications . highlight that managing represents promising strategy incorporating new traits into contemporary forests. Yet, important barriers remain establishment will most likely require management intervention. Nonetheless, broader applicability our demonstrates serve strategic nodes functionally connected landscapes.
