In many forests globally, resilience-focused restoration is necessary to prevent fire-driven regime shifts. However, restoration planning is challenged by limited resources for monitoring biodiversity responses to management intervention and to natural disturbances. Bioregional-scale passive acoustic monitoring, when combined with automated species identification tools and management-relevant habitat data, can be a tractable method to simultaneously monitor suites of complementary indicator species and rapidly generate species-specific information for resource managers. We demonstrate these methods by mapping the occurrence of ten avian indicator species while examining the impact of fire history on patterns of occurrence across 25,000 km² of California's Sierra Nevada mountains. Monitoring complementary indicator species with rapidly developing bioacoustics technology and relating their occurrence to policy-ready habitat metrics have the potential to transform restoration planning by providing managers with high-resolution, ecosystem-scale information that facilitates adaptive management in an era of rapid environmental change.

The extent of built marine infrastructure—from energy infrastructure and ports to artificial reefs and aquaculture—is increasing globally. The rise in built structure coverage is concurrent with losses and degradation of many natural habitats. Although historically associated with net negative impacts on natural systems, built infrastructure—with proper design and innovation—could offer a largely unrealized opportunity to reduce those impacts and support natural habitats. We present nine recommendations that could catalyze momentum toward using built structures to both serve their original function and benefit natural habitats (relative to the status quo, for example). These recommendations integrate functional, economic, and social considerations with marine spatial planning and holistic ecosystem management. As the footprint of the Anthropocene expands into ocean spaces, adopting these nine recommendations at global scales can help to ensure that ecological harm is minimized and that, where feasible, ecological benefits from marine built structures are accrued.

The ecological and developmental history of the Chicago, Illinois, region has affected the current distribution of forests therein. These same factors, along with systemic and long-lasting racial segregation, have shaped the distribution of the urban populations that benefit from the ecosystem services provided by urban forests. This study demonstrates that forest patch history is related to forest attributes like tree species composition, tree density, canopy height, and structural heterogeneity—all of which are important predictors of a forest's ability to provide ecosystem services. However, this effect of forest history was only seen in forest cores, as forest edges were similar regardless of patch history. We also found that forests in minoritized communities tended to be less able to support high levels of ecosystem services. This research indicates that, when improving green equity, it is important to consider the variable capacity of forests to provide ecosystem services.

Efforts to restore habitat for wildlife often target single species, with limited consideration of the potential benefits provided to sympatric species. On the basis of range-wide data from the Fourth National Giant Panda Survey and infrared camera trapping, we used species distribution models to project the outcomes of five habitat restoration scenarios—designed to benefit giant pandas (Ailuropoda melanoleuca)—for giant pandas as well as for sympatric birds and mammals. Scenario outcomes, particularly those involving the conversion of plantation forests and shrublands into suitable forests, demonstrated a significant enhancement in giant panda habitat suitability, but with contrasting effects for sympatric species. Moreover, while restoration of giant panda habitat may enhance species richness and functional diversity, especially when shrublands are converted into forests, such action could also reduce phylogenetic diversity. Our findings suggest that single-species habitat restoration may have negative outcomes for sympatric species, highlighting the need to consider trade-offs between focal and non-focal taxa.

Rewilding is emerging as a promising restoration strategy to tackle the challenges posed by global change and maintain natural ecosystems and their biodiversity. However, rewilding has also been criticized for the absence of a consistent definition and insufficient knowledge about its possible outcomes. Here, we explored the effects of rewilding on filling functional gaps created by the extirpation of native species. We contrasted rewilding with three other mechanisms for change in community composition—species extirpation, species introduction, and unassisted colonization—in terms of their impacts on changes in avian and mammalian diversity in the UK. We found that (i) while rewilding increases functional diversity most on average, introduced/naturalized birds contribute more functional uniqueness to native functional space than other groups of birds; and (ii) changes in functional diversity associated with “rewilded” organisms were species-dependent and idiosyncratic. Our results suggest that although rewilding can expand or infill native functional trait space to some extent, such effects require careful assessment.

The Atlantic Forest harbors one of the most diverse and threatened tropical forest biotas worldwide. Recognized as a global biodiversity hotspot, the biome extends along Brazil's Atlantic coast and into eastern Paraguay and northeastern Argentina, spanning a wide range of latitudinal, longitudinal, altitudinal, and climatic gradients. Its flora includes taxa from the Amazon Rainforest, Cerrado gallery forests, and the Andean region, encompassing approximately 25,000 species of vascular plants, 48% of which are endemic and 3400 of which are trees (Oliveira-Filho and Fontes 2000).

The degradation of the Atlantic Forest reflects centuries of human expansion triggered by the arrival of European colonizers in the 16th century CE. Over time, economic cycles, such as those associated with brazilwood, sugarcane, gold, and coffee, as well as urbanization, ranching, and railway/road construction, have severely impacted the forest (Dean 2013). Today, much of the Atlantic Forest consists of patches of secondary forests at varying stages of recovery, monoculture plantations of non-native trees, and small forest fragments surrounded by open areas dominated by anthropogenic landscapes (Tabarelli et al. 2010). An estimated ~120 million people (70% of Brazil's population) live along Brazil's Atlantic coast, exacerbating pressure on the remaining forest, which currently covers only 12% of its original extent (SOS Mata Atlântica 2023). In this context, urban expansion, industrialization, intensive agriculture, and mining not only accelerate deforestation and biodiversity loss but also erode the ancestral knowledge and cultures of Indigenous peoples who have inhabited these lands for millennia.

Currently, Brazil is home to 305 Indigenous peoples who speak 274 different languages. These groups inhabit territories composed of forests and other associated non-forest systems. The differences exhibited by these communities reflect their sociocultural variety, arising from distinct logics, conceptions, and practices specific to each people and shaped by various historical, social, and environmental contexts (Cunha et al. 2022).

Among the Indigenous peoples coexisting within the Atlantic Forest are the Guarani (Guarani Mbya), Kaingang, Pataxó, Tupinambá, and Tupiniquim. For these groups, nature and biodiversity not only are deeply connected with beliefs, knowledge, history, and culture but also depend on management techniques to better ensure their persistence over time. Embedded within multiple dimensions—social, cultural, political, economic, environmental, philosophical, and spiritual—traditional Indigenous knowledge fosters a sustainable way of relating to nature, land, and biodiversity, contributing to landscape and biodiversity conservation (Cunha et al. 2022).

Indigenous cultural practices are expressed through a diversity of songs, dances, c

Musical instruments are indispensable to music traditions worldwide and often made from natural materials derived from species that are increasingly endangered. International trade threatens the survival of some of these species, as addressed by their inclusion in the UN Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). However, CITES regulations can substantially impact music traditions and alone are insufficient to preserve trade-relevant species from extinction, such as the pau-brasil (Paubrasilia echinata), which is used for the bows of stringed instruments. Therefore, new CITES listings of species or species products used in the manufacture of musical instruments, or potential future shifts of CITES-listed species to the strictest category, will require anticipation, preparation, and precautionary actions. In international species trade negotiations, it is crucial to target the protection of species and music traditions beyond trade regulations. We propose novel social–ecological pathways to address these challenges and reconcile conflicting stakeholder interests between species conservation and cultural conservation.
