Vegetation spatial pattern and snow depth in nival gullies in the Tatra Mountains

The data presents characteristic of the spatial pattern of vegetation and data of snow patches disappearance in 2 nival gullies located on the Beskid Mt. and the Uhrocie Kasprowe Mt. in the Tatra Mountains. The gullies are located above the upper timberline (i.e. 1500 m a.s.l) in subalpine and alpine belts. Quantitative studies of the vegetation were carried out in sample plots of 0.5 × 0.5 m, located 0.5 m apart, along the cross-profiles of the studied nival gullies. For each sample plot, the cover of the following was determined: vascular plants, bryophytes, plant litter, rocks, coarse debris, finer materials. The plant species present in the plot were recorded. Species cover (in %) was estimated using the cover class method (Daubenmire 1959). […]
