Even many years after being abandoned, plant diversity of former agricultural sites is still incomplete compared to undisturbed sites
Leipzig/Minnesota. Agriculture is considered a major disturbance for ecological systems – the recovery of degraded or formally used agricultural land might take a long time. However, without any active restoration interventions, this recovery can take an exceedingly long time and is often incomplete, as shown by a team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz Centre for Environmental Research (UFZ). Their study, which was published in the Journal of Ecology, sheds light on the recovery process at different scales in former agricultural sites, pointing to specific restoration interventions that could help biodiversity to recovery.
Land use such as transforming natural habitats into agricultural areas is the most important driver for biodiversity loss worldwide. However, one might assume that, given enough time, removal of major anthropogenic disturbances will allow biodiversity to recover. Ecological restoration is the science and practice of directing and speeding up the recovery of disturbed ecosystems. In accordance with Target 2 of the recently adopted Global Biodiversity Framework of the UN Convention on Biodiversity (CBD), at least 30% of areas of degraded terrestrial, inland water, and coastal and marine ecosystems should be under effective restoration by 2030.
