Abstract

We analyzed modern use of arable lands of 1985 before the collapse of collective and state farms using high resolution space imagery and grid mapping. Two model sites of 10×10 km were used, with the first one located at the northern border of broad-leaved forests of the Bashkortostan Republic ("Mishkinsky"), and the second one located in the forest-steppe ("Belebeyevsky"). In 1985 the area of arable land at the "Mishkinskiy" site was 60% higher than the "Belebeyevskiy" site due to the difference in the slope steepness. Presently, the area of arable land in the "Mishkinsky" and "Belebeyevsky" sites decreased by 72% and 64% respectively. Forest overgrowth covers a little more than half of the initial arable land in both sites. "Mishkinsky" forest stands are dominated by Betula pendula, with Pinus sylvestris dominating the "Belebeyevsky" forests. Abandoned fallows are more often used as hayfields and pastures at the "Mishkinsky" site, while grass vegetation overgrowth share is higher at the "Belebeyevsky" site. In addition, woody vegetation is being cleared at the "Belebeyevsky" site to reuse the land. Young fast-growing forest overgrowth is of great interest as wood source and as a part of carbon farms to achieve carbon neutrality of the Bashkortostan Republic.
