2018 SUNY ESF Findings

  • Primary Otisco Lake invasive species are Eurasian Milfoil and Curly Pond Weed

  • Milfoil has increased its spread and density throughout the lake since 2005

  • Milfoil likely out competing other native species

  • Curly Pond Weed abundant early but dimishes late season

  • Coontail (native reaches high abundance by late season

  • Plant biomass increases as the season progresses
