Published: Jan. 1, 2023

Abstract The increasing effects of climate and global change oblige ecosystem-based management to adapt forestry practices deal with uncertainties. Here we provide an overview identify the challenges facing boreal forest under projected future change, including altered natural disturbance regimes, biodiversity loss, increased fragmentation, rapid loss old-growth forests, need develop novel silvicultural approaches. We specifically address subjects previously lacking from framework, e.g., Indigenous communities, social concerns, ecological restoration, impacts on aquatic ecosystems. conclude by providing recommendations for ensuring successful long-term biome change.

Developing national complementary indicators of SDG15 that consider forest quality: Applications in Colombia, Ecuador, and Peru

Ecological Indicators, Journal Year: 2024, Volume and Issue: 159, P. 111654 - 111654

The UN 2030 Agenda for Sustainable Development Goal 15, termed Life on Land, is monitored by indicators and sub-indicators that largely deal with forest extent. In countries structurally complex species-rich forests, of quality are also needed to effectively monitor sustain ecological integrity. goal the paper demonstrate use complementary SDG15 reporting conservation planning. Our objective apply these within Colombia, Ecuador, Peru evaluate spatial patterns trends over time as a basis revealing how results complement official extent in protected areas informing conservation. quantify naturalness, riparian forest, structure integrity, fragmentation, connectivity.

Investigating LiDAR Metrics for Old-Growth Beech- and Spruce-Dominated Forest Identification in Central Europe

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(2), P. 251 - 251

Published: Jan. 12, 2025

Old-growth forests are essential for maintaining biodiversity, as they formed by the complexity of diverse forest structures, such broad variations in tree height and diameter (DBH) conditions living dead trees, leading to various ecological niches. However, many efforts old-growth mapping from LiDAR have targeted only one specific structure (e.g., stand height, basal area, or density) deriving information through a large number metrics. This study introduces novel approach identifying optimizing set selected standards structural These metrics effectively capture arrangement multiple canopy heterogeneity, multilayer profile, openness. To determine important standard forests, multicollinearity analysis using variance inflation factor (VIF) was applied identify remove with high collinearity, followed random algorithm rank which classification. The results demonstrate that (i.e., advanced related structures) more effective distinguishing old- second-growth than height- density-based metrics) European definition 150-year age threshold forests. were then used predictors final classification yielding an overall accuracy 78%, true skill statistic (TSS) 0.58 test dataset. demonstrates few provides metrics, particularly mixed temperate findings can aid national park managers developing practical efficient identification monitoring method LiDAR.

Big, old-growth European silver fir, beech and oak on high- medium-fertility soils in the Carpathians generate a huge increase trunk volume, total phytomass annual carbon accumulation (25–50 kg). Accordingly, each giant emits lot of oxygen (65–130 kg/yr) water vapour (40–80t/yr), its transpiration consumes 0.03–0.06GWh energy which can cool hectare 30 m × 1 ha air layer by 0.027–0.053°C. Stands spruce stone pine high mountain zone grow more slowly; their current volume material impact surrounding is 3–5 times less but, still, it increases over time. By increasing number big trees forest stands, stand productivity environment be increased 20–40%.

Introduction According to various censuses, Europe has less than 1.5 million ha of old-growth forests (OGF). Most them are in the boreal zone, while their presence temperate zone is residual and fragmented.In framework EU biodiversity strategy, it been adopted a broad definition OGF which includes late-seral with some management legacies. However, research purposes need identify strictly defined OGFs characterized by structure, disturbance history, processes typical exclusive last stage forest dynamic. Methods The present paper wants contribute this debate presenting network four mixed (Fagus-Abies-Picea) montane Dinaric Alps (Lom, BiH; Janj, Perućica, Biogradska Gora, MNE), summarizing 20 years multidisciplinary focusing on structural characteristics history whole coherency strict indicators. These sites were selected relatively structurally uniform study areas, where 142 permanent plots have established since 2002. Results discussion high living (747–1,201 m3 ha−1) coarse woody debris (CWD) biomass (304–410 ha−1), resulting highest carbon sink at continental level (398–484 Mg C ha−1). large old trees one critical stage: Lom there 19 14 ha−1 larger 1 m breast height, respectively, 15 older 400 years. In three centuries, continuous small-scale disturbances driven dynamics, developing stands gap-phase dynamics quasi-equilibrium structure. presents robust indicators old-growthness, similar characteristics, dynamic across all sites. Identifying sub-set using criteria for recognizing conservation priorities quantifying, along an old-growthness chronosequence, current differences managed or recently abandoned forests.

The public-domain International Tree-Ring Data Bank (ITRDB) is an under-utilized dataset to improve existing estimates of global tree longevity. We used the longest continuous ring-width series ITRDB collections as index maximum age for that species and site. Using a total 3,689 collections, we obtained longevity 237 unique species, 157 conifers 80 angiosperms, distributed all over world. More than half (167) were represented by no more 10 similar number (144) reached greater 300 years. Maximum ages exceeded 1,000 years several (22), them conifers, whereas angiosperm peaked around 500 Given current emphasis on identifying human-induced impacts systems, detailed analyses holdings provide one most reliable sources information ecological trait.
