The subbase of the area is formed by the Mesozoic square sandstone of the lower Turonian stage, that is covered by Quarternary sandstone drifts from the Chřibské Kamenice Stream. A river flood plain with side springs intersects the protected area and its surroundings. The adjacent meadows were used as pasture for cattle in the past which has significantly influenced the composition of the meadow vegetation. To name but a few plant species growing on the banks of the Chřibské Kamenice River: Goats Beard, Spiked Rampion, Maiden Pink and Purple Betony. On the left bank of the river there is a blind branch where the occurrence of the endangered and rare species of red algae Batrachospermum sp was recorded; this species can only be found in clean waters. A typical species living in this type of habitat is for example the Golden-ringed Dragonfly. Quite often you will find trout in the river, and there are nests of the Common Kingfisher, White-throated Dipper and Grey Wagtail. The European Otter is often recorded here. There have also been attempts to reintroduce the silver salmon. The banks of the river are lined with alder trees and willows. Fallen trees are removed from the river bed to enable a smooth flow of the stream; plants species that are not indigenous are removed, such as the Japanese Knotweed and Himalayan Balsam.
