Impact of Forest Management on Species Richness: Global Meta-Analysis and Economic Trade-Offs

Scientific Reports, Journal Year: 2016, Volume and Issue: 6(1)

Published: April 4, 2016

Abstract Forests managed for timber have an important role to play in conserving global biodiversity. We evaluated the most common production systems worldwide terms of their impact on local species richness by conducting a categorical meta-analysis. reviewed 287 published studies containing 1008 comparisons and unmanaged forests derived management, taxon continent specific effect sizes. show that loss, forest management types can be ranked, from best worse, as follows: selection retention systems, reduced logging, conventional selective clear-cutting, agroforestry, plantations, fuelwood plantations. Next, we calculated economic profitability net present value harvesting 10 hypothetical wood-producing Forest Management Units (FMU) around globe. The ranking is altered when loss per unit profit generated FMU considered. This due differences yield, prices, rotation cycle length costs. thus conclude it would erroneous dismiss or prioritize regimes, based solely alpha diversity impacts.

Multiple forest attributes underpin the supply of multiple ecosystem services

Nature Communications, Journal Year: 2018, Volume and Issue: 9(1)

Published: Nov. 12, 2018

Trade-offs and synergies in the supply of forest ecosystem services are common but drivers these relationships poorly understood. To guide management that seeks to promote multiple services, we investigated between 12 stand-level attributes, including structure, composition, heterogeneity plant diversity, plus 4 environmental factors, proxies for 14 150 temperate plots. Our results show attributes best predictors most also good several trade-offs services. Environmental factors play an important role, mostly combination with attributes. study suggests managing forests increase structural heterogeneity, maintain large trees, canopy gaps would These highlight potential encourage multifunctional suggest a coordinated landscape-scale strategy could help mitigate human-dominated landscapes.

The impact of even‐aged and uneven‐aged forest management on regional biodiversity of multiple taxa in European beech forests

Journal of Applied Ecology, Journal Year: 2017, Volume and Issue: 55(1), P. 267 - 278

Published: June 5, 2017

Abstract For managed temperate forests, conservationists and policymakers favour fine‐grained uneven‐aged (UEA) management over more traditional coarse‐grained even‐aged (EA) management, based on the assumption that within‐stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for first time how differently grained forest systems affect biodiversity of multiple above‐ below‐ground taxa across spatial scales. sampled 15 animals, plants, fungi bacteria within largest contiguous beech landscape Germany classified them into functional groups. Selected stands have been than a century at different grains. The EA (coarse‐grained management) UEA (fine‐grained) forests are comparable in arrangement, climate soil conditions. These were compared nearby national park unmanaged least 20 years. used diversity accumulation curves compare γ‐diversity Hill numbers 0 D (species richness), 1 (Shannon diversity) 2 (Simpson between systems.

Replacing monocultures with mixed-species stands: Ecosystem service implications of two production forest alternatives in Sweden

AMBIO, Journal Year: 2016, Volume and Issue: 45(S2), P. 124 - 139

Published: Jan. 7, 2016

Whereas there is evidence that mixed-species approaches to production forestry in general can provide positive outcomes relative monocultures, it less clear what extent multiple benefits be derived from specific alternatives. To such insights requires evaluations of an encompassing suite ecosystem services, biodiversity, and forest management considerations provided by mixtures monocultures within a region. Here, we conduct assessment Sweden contrasting even-aged Norway spruce (Picea abies)-dominated stands, with stands birch (Betula pendula or B. pubescens), Scots pine (Pinus sylvestris). By synthesizing the available evidence, identify including increased water quality, esthetic recreational values, as well reduced stand vulnerability pest pathogen damage. However, some uncertainties risks were projected increase, highlighting importance conducting comprehensive interdisciplinary when assessing pros cons mixtures.

This is reflected unexpected disturbance events, as well new and increasing socio-economic demands, all of which are affecting resilience forest worldwide provision important ecosystem services. Anthropocene era forcing us to reconsider past current management silvicultural practices, search for ones that more flexible better at dealing with uncertainty brought about by these accelerating cumulative global changes. Here, we briefly review focus limitations practices mainly developed Europe North America. We then discuss some recent promising concepts, such managing forests complex adaptive systems, approaches based resilience, functional diversity, assisted migration multi-species plantations, propose a novel approach integrate functionality species-traits into network multi-scale way manage Anthropocene. takes consideration high level associated future environmental societal It relies quantification dynamic monitoring diversity indices network.

Understanding the importance of primary tropical forest protection as a mitigation strategy

Abstract Given the short time-frame to limit global warming, and current emissions gap, it is critical prioritise mitigation actions. To date, scant attention has been paid benefits of primary forest protection. We estimated tropical ecosystem carbon stocks flows. The stock forests at 141–159 Pg C (billion tonnes carbon) which some 49–53% all carbon, living biomass component alone 91–103% remaining budget warming below 1.5 degrees above pre-industrial levels. Furthermore, have ongoing sequestration rates 0.47–1.3 yr −1 , equivalent 8–13% annual anthropogenic CO 2 (carbon dioxide) emissions. examined three main forest-based strategies used in land sector—halting deforestation, increasing restoration improving sustainable management production forests. protection are contingent upon how degradation defined accounted for, while those from also depend on understood applied.
