Details of this species in Lake Tarawera
Source: Wells et al. 1997
Species Notes for this Location:
E. canadensis was the first to invade the lake followed by L. major which became the dominant tall-growing species to 6 m depth. Comparisons of lake survey data for macrophytes in Lake Tarawera from 1988 and 1993/94 show that marked changes occurred in the composition and patterns of submerged vegetation as a result of a recent invasion by C. demersum. There were no reports of a weed nuisance in Lake Tarawera until L. major became established. By 1969, L. major was common in sheltered areas of the western shoreline of Lake Tarawera and Coffey (1970) concluded the plant was in an early stage of invasion, based on its limited distribution and abundance. The dispersal of L. major to southern shores of the lake, and its spread west of Hot Water Beach occurred in the mid 1980s (authors' unpubl. data) (Wells et al. 1997).
