They have developed an intimate and profound relationship with the environment, and their use of native plants in food and medicine is largely. Over 500 different clan groups or nations with distinctive cultures, beliefs, and languages have learnt to live sustainably and harmoniously with nature.

Our research shows the importance of archival remote sensing materials and indicates their role in understanding ALA-related forest cover change in Poland over the last 50 years. Additionally, analysis of forest pattern change revealed that although forest core areas have increased since 1970, its share in total forest cover decreased due to newly established small forest patches. The output of vegetation height analysis confirmed significant land use transformation from non-forest and ALA into forest area. The information from archival materials is compared with current High-Resolution Layers and airborne laser scanning products, indicating that a forest cover increase of 23% was observed. In this paper we use the declassified CORONA satellite imagery (1969) to backdate the information on land cover and land abandonment from topographic maps from 1970s for the region located in central Poland and currently affected by widespread ALA. So far, many studies of ALA have been done in the mountainous areas in Poland, but less is known about the magnitude. Though considered to be a negative phenomenon, ALA opens up several options for planning future land uses critical for biodiversity conservation or future carbon sequestration. Nowadays, Poland is one of the European countries most affected by agricultural land abandonment (ALA).
