The spacious concave sinkhole has created an unusual inverse distribution of vegetation.

Smrekova draga Cold Hollow is part of the Golaki forest reserve. The vegetation zones are lined up from the upper margin to the bottom in an altitude difference of less than 200 m. The upper margins are covered with beech forest, below followed by pine and spruce trees, whereas the bottom of the sinkhole is covered by bush, dwarf shrubs, mountain grass and moss.

The reversed order of vegetation zones is conditioned by the relief of the area. The sinkhole is enclosed by mountain ridges which obstruct air flow in it. Therefore it creates a specific mesoclimate with a still atmosphere, a higher relative air humidity and frequent mist. The snow that accumulates at the bottom melts very slowly in the spring time and therefore cools the air and the ground. The air temperature gradually drops from the upper margin towards the bottom of the sinkhole. Smrekova draga thus has a double “mountainous” inversion – the climatic and the vegetal.
