Geocache Description:


Prírodní rezervace Cerná Louka
Nature reservation Cerná Louka


Prírodní rezervace Cerná Louka byla zrízena roku 1998 na ploše 130ha k ochrane zachovalého komplexu mokradních luk a rašeliništ, typických pro náhorní planinu nejvýchodnejšího Krušnohorí v nadmorské výšce od 690m.n.m. do 760m.n.m.

Geologické pomery:
Geologické podloží celého území prírodní rezervace tvorí krystalické horniny proterozoika starší 500 miliónu let, poprípade sporadická telesa o neco mladších prvohorních vyvrelin. Rudní žíly vázané na tyto horniny byli všude v okolí dobývány od stredoveku do dvacáteho století.
Vzhledem k nadmorské výšce a vysokých srážkovým úhrnum zde v raném postgalicálu vznikly podmínky príznivé pro vznik rašeliništ.

Flóra a fauna:
Predpokládanou puvodní vegetací byly horské acidofilní buciny a rašelinné smrciny. Ty byly pozdeji nahrazeny pastvinami a loukami. Cást okolí byla postižena odvodnením okolí a úpravou vodotece tvorící prítok nedalekého hranicního toku. Jedná se o biologicky i zoologicky jedno z nejhodnotejších území východních Krušných hor.

2. Jmenujte alespon 3 zástupce flóry.
3. Jaká je dominantní rostlina pro tuto oblast?

Nature reservation Cerná Louka was estamblished in 1998 on 130ha area to protect proved complex of wetland meadows and peat moors which are typically for Ore mountain´s eastermost upland in altitude from 690 meters above sea to 760 meters above sea.

Geologic´s situation:
Geologic subsoil of all reservation forms crystalline rocks proterozoica which are 500 milions years old. Or younger sporadically objects forms by Palaeozoic eruptive rocks. Ore lode which are blocked in in this rocks were mined from medieval times to 20th century.
Because of  very good altitude and precipitation amounts were the favourable conditions forms here in early postglacial age.

Biota:
The supposed original vegetation are acidophilic beach-trees and peaty pine-trees. Afterwards, they were replaced by meadows and pastures. The part of the surrounding was later disastered by drainage and by adjustment of drainage channel which form tributary of close borderline river. The reservation is biologically and zoology  very important area of eastern Ore Mountains.
