Biodiversity monitoring represents a major challenge to supporting proper forest ecosystem management and biodiversity conservation. The latter is indeed shifting in recent years from single-species multi-taxon approaches. However, multi-taxonomic studies are quite rare due the effort required for performing field surveys. In this context, remote sensing powerful tool, continuously providing consistent open access data at different range of spatial temporal scales. particular, Sentinel-2 (S2) mission has great potential produce reliable proxies biological diversity. beech forests two Italian National Parks, we sampled beetle fauna, breeding birds, epiphytic lichens.

Combined retention of large living and dead trees can improve provision of tree-related microhabitats in Central European montane forests

Abstract Retention of habitat trees is a common biodiversity conservation practice in continuous cover forests temperate Europe. Commonly, living are selected on the basis their tree-related microhabitats (TreMs) such as cavities or crown deadwood. Owing to increasing frequency and intensity climate change-related disturbances, particular expected experience increased mortality rates. This may impact long-term provisioning TreMs. Here, we compared TreM occurrence dead investigate whether support more other TreMs than trees.

Close-to-nature forest management effects on soil nematodes and microbial activity in pine plantations on aeolian sands

Community Ecology, Journal Year: 2024, Volume and Issue: unknown

Published: April 29, 2024

Abstract Close-to-nature forest management combines the economic use of forests with nature conservation in forest, aiming promote stability, productivity, diversity and continuity within ecosystems. While close-to-nature is expected to positively impact tree growth, its effect on belowground micro-biota has been poorly investigated. Nematodes microbes are species-rich abundant soil microorganisms that have long used as ecological indicators health.

Trade-off analysis for multi-objective boreal forest thinning

Forestry An International Journal of Forest Research, Journal Year: 2025, Volume and Issue: unknown

Published: April 24, 2025

Abstract Thinning is an essential forest management activity because it recovers capital from stands, increases the relative value growth of remaining trees, and affects other ecosystem services. Optimizing selection harvested retained trees requires understanding how thinning decisions affect different objectives. We studied trade-offs between multiple indicators economic benefits, landscape amenity, tree size inequality, spatial order species mixture, retention in 35 field plots Finnish boreal forest. Tree was optimized for single goals, limiting only basal area so that solutions were practical legal. Maximizing objectives resulted a “thinning above” treatment, i.e. selecting larger harvest. index or amenity resembled below” treatment. ecological favored leaving deciduous standing. Fixed harvesting rules cannot achieve all because, e.g. optimizing conflicts with most environmental indicators. Reasonable can be achieved through multicriteria optimization as shown this paper. Overall, approach improve precision forestry, where operations are planned at detailed scales to account within-stand variation structure.

Red lists provide limited information on habitat associations species, which could be relevant in informing management conservation measures. We used documented empirical data expert assessments to determine for each red-listed (IUCN categories Near Threatened, NT; Vulnerable, VU; Endangered, EN; Critically CR; Regionally Extinct, RE) species Finland following key associations: host tree substrate type, geographical distribution, preferred microclimate, minimum required forest age. most important were Picea abies (L.) H. Karst. Populus tremula L. Other high importance included Sorbus aucuparia Salix caprea One fourth lichens primarily lignicolous. Most old-growth (required by 41% species) or old trees (52%), but many only mature (36%) (35%). microclimatic preferences consisted intermediate light availability humidity. whose status had deteriorated dependent deciduous trees. continuous (especially Populus, Sorbus) requires special attention both managed protected forests.
