The researchers used satellite images and maps to study the landscape diversity in Argun National Nature Reserve. They found that the area is mainly covered by a mix of coniferous and broad-leaved forests, with other landscape types scattered throughout. Forests in early stages of growth had complex shapes and were fragmented, while older forests were more uniform. Overall, the landscape showed lower diversity and a simple structure. These findings can help with conserving biodiversity and planning the management of the reserve.
