Monitoring of species’ genetic diversity in Europe varies greatly and overlooks potential climate change impacts

Abstract: Genetic monitoring of populations currently attracts interest in the context of the Convention on Biological Diversity but needs long-term planning and investments. However, genetic diversity has been largely neglected in biodiversity monitoring, and when addressed, it is treated separately, detached from other conservation issues, such as habitat alteration due to climate change. We report an accounting of efforts to monitor population genetic diversity in Europe (genetic monitoring effort, GME), the evaluation of which can help guide future capacity building and collaboration towards areas most in need of expanded monitoring. Overlaying GME with areas where the ranges of selected species of conservation interest approach current and future climate niche limits helps identify whether GME coincides with anticipated climate change effects on biodiversity. Our analysis suggests that country area, financial resources and conservation policy influence GME, high values of which only partially match species’ joint patterns of limits to suitable climatic conditions. Populations at trailing climatic niche margins probably hold genetic diversity that is important for adaptation to changing climate. Our results illuminate the need in Europe for expanded investment in genetic monitoring across climate gradients occupied by focal species, a need arguably greatest in southeastern European countries. This need could be met in part by expanding the European Union’s Birds and Habitats Directives to fully address the conservation and monitoring of genetic diversity.

Perspektive obnove slovenskih gozdov v času podnebnih in družbenih sprememb
Boris Rantaša, Franc Perko, Gregor Božič, Marjana Westergren, Primož Simončič, Hojka Kraigher, 2023, professional article

Abstract: Trajnostno, sonaravno in večnamensko gospodarjenje s slovenskimi gozdovi je omogočilo ohranjeno biotsko raznovrstnost, ohranjen prilagoditveni potencial ter velik povprečni prirastek in lesno zalogo. Za trajnostno zagotavljanje funkcij gozdov bo potrebno prilagajanje na spreminjajoče se podnebne in družbene razmere. Osrednji ukrep prilagajanja gozdov na podnebne spremembe je povečevanje pestrosti, tudi genetske. Praktično vsi področni strateški, zakonodajni ter operativni dokumenti na nacionalni in evropski ravni prepoznavajo in vsebujejo pomen ohranjanja gozdnih genskih virov in obnove ter nege gozda za trajnostni razvoj in zagotavljanje funkcij gozdov. Gospodarjenje z gozdovi bo treba nadgraditi z ukrepi, ki vključujejo aktiven pristop pri obnovi in negi gozda s čim širšo paleto vrstno in genetsko raznolikih sadik gozdnih drevesnih vrst. V obdobju 2023–2026 bo za obnovo gozdov in semenarsko ter drevesničarsko dejavnost na letni ravni potencialno namenjenih pribl. pet milijonov evrov javnih sredstev. Za obnovo in nego gozda bo nujno zagotoviti stabilno in fleksibilno financiranje zagotavljanja gozdnega reprodukcijskega materiala ter izvedbo obnove gozda in razvoja panoge. Avtorji poudarjajo tudi pomen sodelovanja in skupnega nastopa različnih deležnikov v celotni verigi gozdnega reprodukcijskega materiala.
