Reduction of the potential distribution area of 24 vegetation types identified on the 1961 vegetation map
For this analysis, the vegetation map from the 1961 Atlas of the Armenian SSR* (digitized by Vardan Asatryan) and the ESRI land cover 2023 data were used.
Vegetation map 1961
Vegetation map excluding crops and built-up areas from ESRI 2023
For detailed maps see in the Section Ecosystem Extent/Vegetation
Based on the intersection of the vegetation map with the land cover data, vegetation types have been ranked according to their rarity (area in 2023), and the proportion of their potential area currently occupied has been identified.
