P069: Potential for Pondweed Control in Lake Tahoe Using Bottom Barriers

Curly-leaf pondweed (Potamogenton crispus) is a relatively recent example of a nearshore aquatic invasive species in LT. Due to its recent introduction, and restricted range in the southern portion of LT, curly-leaf pondweed is considered to be in an early invasion stage and thus could be a potential candidate for eradication or control if a feasible methodology can be found. The goal of this research was to study turions produced by curly-leaf pondweed to determine their relationship to plant biomass and assess their susceptibility to non-chemical treatment using gas permeable and impermeable benthic bottom barriers.
