Jasenice quarry (312 m)
Natural monument Jasenice (1.7056 ha) is situated at an altitude of 312–324 m. Flooded and abandoned limestone quarry is protected here. This is a unique outcrop of blocks of Jurassic Štramberk limestones with world-famous fossil invertebrates (corals, bivalves, gastropods, hydrozoans). Limestone mining began here in the 1940s. An underground source of extremely high quality water was released during one of the blasting. Pumping this water gradually became unprofitable and in 1981, the mining was completed. The quarry surface covering an area of 0.67 ha was gradually flooded. During mining, numerous fossil invertebrates were found. The ensuing geological surveys showed that the local limestone is exceptionally rich in paleontological material and the territory was declared a natural monument. In the abandoned limestone quarry, succession of tree species, especially shrubs, initiated. We can find here e.g. Frangula alnus, wild privet, common dogwood, blackthorn and field maple. Non-native black pine was planted here artificially. Thermophilic and xerophilic flora affects here. In the vicinity of the spring, above the pond of the Jasenice quarry can be found small population of an orchid called marsh helleborine. We can see a crayfish in the pond. Furthermore, there was also found swan mussel, several species of hydra etc. GPS: N 49° 31.15190', E 17° 58.14750' Pcr. 1 Marsh helleborine. Pcr. 2 Quarry in 1976.
