They have developed a global map of critical points for soil biodiversity conservation. And most of these spaces are currently in a situation of disprotection. The authors of the study claim that it is time to set priorities in soil management and conservation.
Although soils are the basis of all terrestrial ecosystems, unlike plants and animals, there is still no overall assessment of the critical points for conservation. In a paper published in the journal Nature, 615 soil samples from all continents have been treated their biodiversity (arches, bacteria, fungi, protists and invertebrates) and their functions. They have thus identified the critical points that exist in the world. And they've found that over 70 percent of these points are not in protected areas, so they're vulnerable.
