Ecosystem Services and Ecological Processes
Decreasing landscape carbon storage in western US forests with 2 °C of warmingBackgroundThis study investigates how a 2°C increase in global mean temperature above pre-industrial levels could alter above-ground carbon storage in forests across the western United States, a region already experiencing climate-driven tree mortality, reduced regeneration, and more frequent fire and insect outbreaks. Forest carbon density is treated as a “carbon carrying capacity” controlled by climate and disturbance regimes, and there is concern that warming and drying will shift many areas towards lower carbon forest or non-forest states, with implications for climate mitigation and carbon offset projects.

Don’t judge species on their originsBackgroundThis commentary suggests that the long-standing “native versus non-native species” debate has created a widespread bias in conservation as it encourages the idea that introduced species are inherently harmful, despite limited quantitative evidence supporting broad claims of catastrophic biodiversity loss. As global changes (such as climate change, nitrogen eutrophication, increased urbanization, and other land-use changes) cause ecosystems to be unable to restore to their historical states, categorizing species based on their origin increasingly mismatches ecological reality, influencing policy, funding, and management priorities.

Elevation, aspect, and climate shape blue pine (Pinus wallichiana) biomass and carbon dynamics in the Bhutanese HimalayasBackgroundForests cover over two-thirds of Bhutan and are constitutionally protected, enabling national carbon neutrality. Yet, climate change, increasing temperatures, variable precipitation, and heightened wildfire risk threaten carbon storage capacity and species distributions. Blue pine is a fast-growing, socio-economically important species dominating inner dry valleys between roughly 2200–3000 m, making it an ideal model to understand how elevation and slope aspect regulate biomass accumulation and carbon sequestration under changing climate conditions.

Resilience to Hurricanes is High in Mangrove Blue Carbon ForestsBackgroundWhile many anthropogenic forces threaten the survival of mangrove forests, tropical storms are the most significant non-anthropogenic sources of disturbance. Since mangroves are important carbon sinks, it is important to understand the impacts of tropical storms on mangrove forest structure, function, and carbon stock recovery.

Getting the best of carbon bang for mangrove restoration buckBackgroundMangrove forest restoration projects have a range of benefits, like carbon sequestration, biodiversity conservation, and sustainable development, that are important for different stakeholders. An analysis of the economic benefits and returns of mangrove restoration at country-level scales can encourage future support from these key investors and decision makers.

The natural capital framework for sustainably efficient and equitable decision makingBackgroundThe concept of ‘natural capital’ is increasingly accepted in government and private sector decision-making for its role in sustaining economic and social well-being. However, the field is fragmented, and many applications misuse its foundations in economics and ecology, which this perspective addresses by proposing an integrated framework.

Valuing natural capital and ecosystem services toward the goals of efficiency, fairness, and sustainabilityBackgroundNatural capital (NC) and ecosystem services (ES) are fundamental to sustaining human life, but valuing them requires a whole-system understanding of the interdependencies between humans and nature. Conventional economic valuation, based solely on individual willingness-to-pay, is too narrow for this complex task. Available with subscription or purchase |
Ecosystem services in decision making: time to deliverBackgroundOver the past decade, valuing and protecting ecosystem services has been promoted as a strategy to mainstream conservation globally. While the vision of the Millennium Ecosystem Assessment is gaining traction, a significant scientific and policy-implementation gap remains. Natural capital is often undervalued or ignored in major decisions by governments, businesses, and the public, a problem highlighted by natural disasters and crises where the loss of protective services becomes starkly apparent.

Diverse values of nature for sustainabilityBackgroundDespite 25 years of progress in valuing ecosystem services, a global biodiversity crisis persists, underpinned by a "values crisis." Current policies and decisions often prioritize a narrow subset of market-based instrumental values, ignoring the diverse ways people relate to and benefit from nature. This paper, based on the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Values Assessment, synthesizes over 50,000 sources to address this gap.

Current trends and future directions for integrating social values into mangrove restorationBackgroundDifferent communication styles, governance, and social issues create barriers to successful mangrove forest restoration projects, and may hinder the ability to scale up projects to meet global restoration goals. Incorporating social values and stakeholder preferences into restoration projects can help identify best management practices, promote successful outcomes, and prevent distrust and inequality between restoration practitioners and stakeholders with different needs and perceptions of mangrove forests.
