A rapidly developing forest ecosystem has formed on the former bottom of the Kakhovka reservoir in southern Ukraine [1].
This unexpected ecological shift follows the destruction of the Kakhovka dam, which drained the reservoir and exposed the lake bed to natural succession. The transformation highlights the resilience of local flora and fauna in a region still impacted by conflict.
Russian occupying forces detonated the dam on June 6, 2023 [1]. Three years later, the area has seen a surge of wildlife and the growth of millions of trees [1], [3]. The new landscape is dominated by willow and poplar species that have colonized the exposed sediment.
"We have observed a rapid colonisation of the former reservoir bed by willow and poplar, creating a dense forest in just a few years," Anna Kuzemko said [2].
Ecologist Kuzemko and lichenologist Olexandr Khodosovtsev have led research expeditions to the site to document the biological changes. While some reports suggest the growth is sparse, other researchers describe the formation of a dense canopy [2].
Fieldwork remains dangerous for the scientists. The presence of military technology and unexploded ordnance creates a volatile environment for those studying the land.
"FPV-drones, ‘mavky’ – over our heads you can see anything, which makes field work hazardous," Khodosovtsev said [4].
Local residents also avoid the area due to the risk of landmines. One unnamed resident said people are scared to walk there because of possible mines and unexploded ordnance [5].
Despite these hazards, the area continues to evolve into a unique wilderness. The transition from a man-made reservoir to a forest is occurring at a pace that has surprised researchers who are monitoring the site's biodiversity [1], [2].
“"We have observed a rapid colonisation of the former reservoir bed by willow and poplar, creating a dense forest in just a few years."”
The emergence of a forest on the Kakhovka reservoir bed represents a massive, unplanned ecological experiment in natural succession. While the biological recovery is rapid, the land remains a high-risk zone due to military contamination, meaning the area will likely function as a restricted wilderness preserve rather than a usable agricultural or residential space for the foreseeable future.
