Forests on the radar

October 21, 2019

The quantity and diversity of plants and animals, especially insects, is decreasing, also in Germany. For this reason, science would like to see opportunities to document the biodiversity of the planet as extensively and comprehensively as possible. In this way, it could be determined whether measures against the insect dieback are effective or not.

Satellite data are well suited for this purpose. "So far, however, they have hardly been used. Scientists were of the opinion that there were no freely available data that would provide sufficientresults," says Professor Jörg Mueller from the Biocenter of Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany. This is not true. Radar data available free of charge can be used very well to monitor biodiversity from space.

This was reported by Mueller's colleague Dr. So-yeon Bae with an international team in Nature Communications. The South Korean landscape ecologist has shown in the research project DFG Biodiversity Exploratories that radar data from satellites are surprisingly well suited for describing the diversity of vertebrates, plants and fungi in forests, as well as the smallest insects and spiders. This is despite the fact that radar data are relatively coarse and despite the fact that forests with their highly dynamic and complex three-dimensional structure represent a particular challenge for monitoring biodiversity.

Twelve species groups analysed in five forest areas

The JMU-led research team compared two methods. In five forest areas, whose biodiversity was very well known by by ground truths, twelve species groups were analysed - on the one hand with high-resolution laser scanning data and on the other hand with coarser radar data.

The results were astounding: "The free radar data provide comparably good results and are sometimes even superior to the laser," says Dr. Bae. Her conclusion: "Remote sensing is ready to carry out biodiversity monitoring from space throughout Germany. Now only better, standardized biodiversity data have to be collected on the ground nationwide". This would require spatially distributed mapping of species diversity in all forest habitats in Germany.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies.
