Decreasing landscape carbon storage in western US forests with 2 °C of warming

Background

This 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.

Global, multi-scale standing deadwood segmentation in centimeter-scale aerial images

Background

This article examines how increasing tree mortality worldwide creates an urgent need for efficient approaches to map standing deadwood, including both fully dead crowns and partial canopy dieback, as a basis for monitoring forest dieback and informing management across biomes. Existing remote-sensing methods using RGB aerial imagery often work only for specific regions, resolutions, or forest types, limiting their transferability and value for global applications.

Resilience to Hurricanes is High in Mangrove Blue Carbon Forests

Background

While 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.

Bridging conservation and policy: evaluating national targets to reduce mangrove loss under the Kunming–Montreal biodiversity framework

Background

This research examines the alignment between the Kunming–Montreal Global Biodiversity Framework (GBF) targets and national efforts to halt mangrove loss. Under the Convention on Biological Diversity, GBF’s Targets 1 and 3 aim to reduce habitat loss and expand protected areas to conserve 30% of critical ecosystems by 2030. Mangroves, vital for biodiversity, carbon storage, and coastal protection, continue to experience degradation due to both human and natural drivers. Despite partial success in global mangrove protection, national policies often fail to address underlying drivers of degradation or incorporate specific, measurable conservation actions.

The enduring world forest carbon sink

Background

Forests are critical to mitigating climate change because they absorb atmospheric carbon dioxide (CO₂) and store it in biomass and soils.  In 2023, atmospheric CO₂ levels exceeded 420 ppm, intensifying the urgency to understand terrestrial carbon sinks. Forests historically lost 180 Pg of carbon through land-use change, yet they remain central to achieving global net-zero goals by 2050. While remote sensing and modeling offer insights, this study emphasizes long-term, ground-based forest inventory data as the most reliable source for assessing trends in carbon sinks across boreal, temperate, and tropical forest biomes.

Putting seedlings on the map: Trade‐offs in demographic rates between ontogenetic size classes in five tropical forests

BACKGROUND:

The study examines tropical forests in regions such as Panama, Puerto Rico, Malaysia, Taiwan, and Ecuador, which are characterized by their high biodiversity and significant environmental challenges like cyclonic storms. These forests are ideal for investigating demographic trade-offs due to their diverse coexisting tree species that align along growth, survival, and stature recruitment axes. The forests have experienced varying levels of disturbance from natural events, making them unique examples for studying tree species’ life-history strategies and the mechanisms that facilitate species coexistence.

How to Achieve Effective Participation of Communities in the Monitoring of REDD+ Projects: A Case Study in the Democratic Republic of Congo (DRC)

BACKGROUND:

The Miombo woodlands of southern Africa represent one of the region's most extensive dry forest ecosystems, spanning several countries and supporting the livelihoods of over 100 million people. These woodlands have undergone significant environmental degradation over recent decades, primarily driven by shifting cultivation, charcoal production, and unsustainable land-use practices. Given their ecological importance and critical role in rural livelihoods, particularly among low-income people, understanding and promoting sustainable management of Miombo woodlands is essential for both environmental conservation and socioeconomic development.
