Curly-leaf distribution ‣ Documented in 730 lakes; probably occurs in many more ‣ Most are found in the central transition forest landtype (min of 5% of all lakes w/ DNR ID#’s). ‣ Speculation that range is expanding northward
Curly-leaf pondweed life history ‣ Produces turion propagules in summer. ‣ Turion production is correlated with temperature and photoperiod ‣ Turions sprout in fall and plant overwinters green ‣ Boom-bust growth in south, not so in the north ‣ Good info on life history; not on ecosystem effects
