Taking the pulse of Earth’s tropical forests using networks of highly distributed plots

Background

Tropical forests play a critical but complex role in global carbon cycling, biodiversity conservation, and climate regulation. These complex dynamics are due to spatial heterogeneity and varying disturbance regimes. Traditional monitoring approaches often rely on remote sensing, which may not capture fine-scale ecological processes. In response, global scientific collaborations have developed extensive forest plot networks to monitor forest structure, biomass, and ecological changes over time. These distributed plots provide high-resolution, ground-based insights into tropical forest conditions across continents.

Long-term (1990–2019) monitoring of forest cover changes in the humid tropics

Background

Tropical moist forests are essential for biodiversity, climate regulation, and global carbon storage, yet they face increasing pressure from deforestation and degradation. Accurate, long-term monitoring of forest dynamics is necessary to support climate policies, including REDD+ and Nationally Determined Contributions (NDCs). Previous studies have provided partial insights, but a comprehensive spatial and temporal characterization of forest degradation and recovery remains limited. Advances in satellite imagery and cloud computing now enable consistent monitoring at pantropical scales.

Belize National Forest Monitoring System 2001-2020

Background

Belize’s diverse ecosystems, land tenure systems, and land-use dynamics require a robust and flexible National Forest Monitoring System (NFMS). Early efforts focused on establishing permanent forest inventory plots in the late 1990s to address data gaps in forest structure and carbon dynamics. Over time, Belize has expanded its forest monitoring framework to integrate both ground-based and remote sensing approaches, ensuring transparency, consistency, and national ownership of forest data systems.

User-Driven Land Cover Change Prediction Map Tool for Land Conservation Planning

Background

Effective conservation planning requires forward-looking tools that anticipate land cover change, rather than relying solely on historical analysis. Rapid urbanization and land-use change threaten ecosystems and biodiversity, particularly in regions experiencing development pressure. Traditional models often lack accessibility for nontechnical users, limiting their application in real-world decision-making. Integrating machine learning with user-friendly platforms can enhance stakeholder engagement and improve conservation outcomes.

Afforestation and Reforestation Have Varying Biodiversity Impacts Across and Within Biomes

Background

Afforestation and reforestation (AR) are widely promoted as nature-based solutions (NbS) for carbon dioxide removal and climate mitigation. Global initiatives aim to expand forest cover significantly to meet climate targets. However, AR can produce unintended biodiversity impacts, particularly when implemented in ecosystems such as grasslands or savannas, where native species are not adapted to forest conditions. The ecological outcomes of AR vary across biomes and species, highlighting the need for spatially explicit, biodiversity-sensitive planning frameworks.

Strong Climate Mitigation Potential of Rewetting Oil Palm Plantations on Tropical Peatlands

Background

Tropical peatlands store vast quantities of carbon and therefore play a crucial role in global climate regulation. In Indonesia, extensive areas of peatland have been drained and converted to oil palm plantations and other agricultural uses. Drainage exposes peat to oxygen, accelerating decomposition and releasing large amounts of carbon dioxide into the atmosphere. Since degraded peatlands are estimated to contribute significantly to global greenhouse gas emissions, restoration strategies such as peatland rewetting have gained increasing attention as potential natural climate solutions.
