    T hird, how can the monoecious
form of hydrilla cause problems worse
than that alread y caused by the dioe-
cio us form? For example in Florida,
hydrilla dom inates man y bodies of
water replacing all submersed pla nts,
blocks water flow, restricts many
water use acti vities, and forms mats
so dense that birds and oth er sma"
an imals walk on them . Will the mono-
ec ious hyd ri lla replace these mats of
dioeci ous hydrilla? Will those mats of
monoecious hydrill a be any more ob-
