“…Unglaciated ranges show a variety of trends. The increase of median gradient with altitude, which is common in the Alps (Robl et al, 2011) is found only in Baiului (11: Fig.3) and Ciucaş (10), and weakly in Suhard (5). Cernei (29) and Vlădeasa (31) show the opposite trend, a gentle decline with altitude, with steepest gradients below 1450 and 1550 m respectively.…”

SRTM1 DEMs for many mountain ranges in Romania were processed to provide slope gradient distributions for each 50 m band of altitude. The effects of cirques are seen in an increase in standard deviation of gradient, and a spread in all percentiles, especially an increase in the 95 th , at relevant altitudes. Otherwise, variations in median gradient with altitude differ between ranges, and do not show the general increase found in the Alps below cirque floor altitudes by [15], [9] and [16].I.

“…It is hypothesized that glacial erosion produced low-gradient cirque floors around former snowlines (ELAs) in the last 470 ka [3] in the Romanian Carpathians. During the LGM, moraines formed at 900-1300 m ( [10] and references therein). ELA was at 1700 m in the Southern Carpathians and at 1250 m in the Eastern Carpathians [10,11,12,13].…”

Some uncertainty in determination of former snowlines is caused by the possible presence of icecaps on some plateaux [14] The effects of glacial erosion were complicated by temporal variations in snowline (of the order of 1000 m in the Late Quaternary) and may be masked by other processes (tectonic and fluvial).…”

Despite a long‐term human impact, Central and Eastern Europe exhibit patches of steppe ecosystems having the highest plant species diversity worldwide. These unique ecosystems have persisted over millennia even though the local climatic conditions would support the formation of a closed forest. Several sources of disturbances have contributed to the persistence of the forest‐steppe landscape such as grazing, fire events and human impact. These disturbances have been recorded in local erosion rates. To gain a deeper understanding of the soil dynamics we aimed at deciphering the long‐ and short‐term erosion rates and the age of the soil mantle. The steppes in Transylvania, Romania, were studied to find evidence of a Holocene continuity of grasslands. Long‐term (millennia) average erosion rates were determined using meteoric 10Be in soils and in situ 10Be of rock outcrops (scarp). Long‐term rates were also estimated by the percolation theory. Short‐term (last few decades) erosion rates were obtained from 239+240Pu in soils. The soils started to form prior to the Last Glacial Maximum, probably during the Eemian Interglacial. The average, long‐term erosion rates varied between 0.18 and 0.63 t ha−1 yr−1. These rates are slightly elevated compared to expected soil erosion rates. The soils of the Transylvanian Plain formed over a long period and reached a quasi‐steady state (soil production equals denudation) that contributed to the maintenance of a biodiversity‐rich forest‐steppe landscape. The slightly elevated erosion rates are an effect of factors that contributed to the Holocene continuity (fire, grazing) and indicate open rather than a forested character of the landscape during soil development. During the last few decades, the erosion rates increased by a factor of 5–10, with values in the range of 1.31–4.05 t ha−1 yr−1. These large differences are caused by changes in human management of the soils. The biodiversity‐rich forest‐steppe landscapes are now under threat.
