Project Summary

Potamogenton crispus,or curly-leaf pondweed, is a relatively recent example of a nearshore aquatic invasive species in Lake Tahoe. Because of its unique life history traits, including turion production, this species has competitive advantages over native aquatic plants. Due to its recent introduction, and restricted range in the southern portion of Lake Tahoe, 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 (vegetative buds) 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.
