Safeguarding Earth's tree diversity is a conservation priority due to the importance of trees for biodiversity and ecosystem functions services such as carbon sequestration. Here, we improve foundation effective global by analyzing recently developed database species covering 46,752 species. We quantify range protection anthropogenic pressures each develop priorities across taxonomic, phylogenetic, functional dimensions. also assess effectiveness several influential proposed prioritization frameworks protect top 17% 50% areas. find that an average 50.2% species' occurs in 110-km grid cells without any protected areas (PAs), with 6,377 small-range fully unprotected, 83% experience nonnegligible human pressure their on average. Protecting high-priority thresholds would increase proportion 65.5% 82.6%, respectively, leaving many fewer (2,151 2,010) completely unprotected. The identified match well Global 200 Ecoregions framework, revealing large part optimize terrestrial overall. Based estimates >46,000 species, our findings show receive limited current PAs are under substantial pressure. Improved overall strongly benefit diversity.

Recognizing the equity implications of restoration priority maps

Environmental Research Letters, Год журнала: 2022, Номер 17(11), С. 114019 - 114019

Abstract A growing number of studies seek to identify global priority areas for conservation and restoration. These often produce maps that highlight the benefits concentrating such activity in tropics. However, potential equity implications using these prioritization exercises guide policy are less explored articulated. We those issues by examining a widely publicized restoration map as an illustrative case. This is based on analysis sought places where agricultural land might provide greatest biodiversity carbon sequestration at lowest cost. First, we calculate proportion countries around world classifies top 15% priority. regression shows this prioritizes displacing agriculture may be most detrimental livelihoods: poorer, more populated, economically unequal, food secure, employ people agriculture. Second, show through another similar pattern appears sub-nationally within tropics: 5 km × parcels tropics developed or populated likely priorities. In other words, concerns persist subnational scale even after putting aside comparisons between Global North. Restorative beneficial harmful local livelihoods depending its conceptualization, implementation, management. Our findings underline need better attend risks potentially negative livelihood impacts vulnerable regions. join scholars calling greater integration social data into science.

Personalised ecology and the future of biodiversity

Cambridge Prisms Extinction, Год журнала: 2023, Номер 1

The future of biodiversity lies not just in the strategies and mechanisms by which ecosystems species are practically best protected from anthropogenic pressures. It also, perhaps foremost, many billions decisions that people make that, intentionally or otherwise, shape their impact on nature conservation policies interventions implemented. Personalised ecology - set direct sensory interactions each us has with is one important consideration understanding make. Indeed, it long been argued people's personalised ecologies have powerful implications, as captured such concepts biophilia, extinction experience shifting baselines. In this paper, we briefly review connections between biodiversity, ways might usefully be enhanced to improve future.

Community forest governance and synergies among carbon, biodiversity and livelihoods

Nature Climate Change, Год журнала: 2023, Номер 13(12), С. 1340 - 1347

Abstract Forest landscape restoration has emerged as a key strategy to sequester atmospheric carbon and conserve biodiversity while providing livelihood co-benefits for indigenous peoples local communities. Using dataset of 314 forest commons in human-dominated landscapes 15 tropical countries Africa, Asia Latin America, we examine the relationships among sequestered above-ground woody biomass, tree species richness livelihoods. We find five distinct clusters commons, with trade-offs on multiple dimensions. The presence formal community management association participation rule-making are consistent predictors positive outcomes. These findings, drawn from range contexts globally, suggest that empowered governance may support objectives restoration. Our analysis advances understanding institutional aspects underscoring importance analysing interconnections benefits inform effective interventions multifunctional forests.
