A new scientific review outlines how satellites and other remote sensing technologies are increasingly shaping how biodiversity and ecosystem health can be monitored at scale—offering new opportunities for countries reporting under international nature targets, while also underscoring important limitations.
Published in Nature Reviews Biodiversity, the study synthesizes current knowledge on the use of satellite-based Earth observation, LiDAR, radar and airborne sensing to track changes in ecosystems across the planet.
The review focuses on a central challenge for the Kunming–Montreal Global Biodiversity Framework (GBF): how countries can consistently measure and report on the state of biodiversity across large and often inaccessible regions.
Tropical forests are highlighted as a critical case study. They contain a disproportionate share of global biodiversity, deliver essential nature contributions to people, and are increasingly affected by climate change, land-use change and disturbance.
What satellites can already track
The authors show that remote sensing is becoming increasingly important for monitoring aspects of forest structure, biomass, canopy traits and ecosystem functioning. These data allow researchers to assess how forests resist, recover from and adapt to environmental change—key components of ecosystem resilience.
The review also notes that satellite data can provide indirect indicators, or "proxies," for different dimensions of biodiversity, including functional and taxonomic diversity, and to a more limited extent phylogenetic and genetic diversity. These links are increasingly relevant to biodiversity monitoring frameworks such as Essential Biodiversity Variables.
Where space-based monitoring falls short
However, the authors emphasize that remote sensing cannot yet provide a complete picture of biodiversity. Many important dimensions—including species turnover, evolutionary history and genetic diversity—remain difficult to observe directly from space and continue to rely on field-based measurements.
They therefore stress that satellite observations must be integrated with ground-based ecology to produce robust and reliable biodiversity assessments.
New sensors will widen the view
Looking ahead, the study highlights that next-generation satellite missions and improved sensor technologies, including hyperspectral imaging, LiDAR and radar systems, are expected to significantly expand what can be measured from space in the coming years.
The research was led by Dr. Jesús Aguirre-Gutiérrez, associate professor and group lead of biodiversity and Earth observation at the University of Oxford's Environmental Change Institute (ECI), and also associate professor and NERC Independent Research Fellowship (IRF) based at Imperial College London, where he leads the Biodiversity & Remote Sensing Lab.
Aguirre-Gutiérrez said, "Remote sensing is transforming how we can observe biodiversity and ecosystem change at large scales. Satellites now provide unprecedented information on forest structure and function, helping us understand how ecosystems respond to disturbance.
"However, this is not a complete solution. Many dimensions of biodiversity are still difficult to observe directly from space, which is why combining satellite data with field observations remains essential. Future satellite missions will continue to expand what we can measure, but biodiversity monitoring will always depend on integrating multiple sources of evidence."
Co-authors include researchers from the University of Oxford and international partners across the U.K., Mexico, the U.S., South Africa and Japan.
The authors conclude that while satellite technologies are rapidly improving the ability to observe and track ecosystems globally, effective biodiversity monitoring under the Global Biodiversity Framework will depend on combining remote sensing with field ecology and emerging biodiversity data frameworks.
