Other Site Characteristics

Väster om Gärdserum avvattnas Båtsjön av Storån som fortsätter i ett meandrande lopp åt sydost genom Uknadalens sprickdalslandskap. Våtmarken, som börjar direkt vid sjöns utlopp är en stor, öppen våtmark som ligger i ett öppet jordbrukslandskap. Våtmarken betas till stora delar. I fältskiktet påträffas många arter som trivs i fuktiga till blöta miljöer. I ohävdade partier finns alskog och videsnår där fältskiktet domineras av bladvass och säv. Mindre partier av fastmark finns ute i våtmarken och i södra delen står enstaka, vidkroniga och metergrova ekar. I området öster om Gärdserum finns inslag av betade sötvattensstränder som kan beskrivas som trädlösa, öppna starrmader med inslag av vegetationstyper som gräs-lågstarräng och tuvtåtelfuktäng.

4.2 Quality and importance

Storåns meandrande lopp utgör en mycket värdefull geologisk formation. Naturvärdena i anslutning till våtmarken vid Båtsjöns utlopp och strandängarna vid Gärdserum är också sammantaget mycket höga. Våtmarkens storlek och det faktum att den som helhet hävdas är en betydelsefull faktor. I vissa stycken hyser våtmarken en mycket artrik flora och den har sannolikt höga värden för fågellivet och organismgrupper knutna till vattenmiljöer. Stora betade sötvattenstränder som uppvisar typiska vegetationszoneringar är sällsynta. De grova fritt stående ekarna i området hyser rödlistade arter. Området utgör en av värdekärnorna i riksintresset Uknadalen och har genom sitt läge i dalgången ett mycket stort värde för landskapsbilden.
