Water Level Regulation

In Canada, Lipocarpha micrantha has been documented at eight locations in Quebec, Ontario, and British Columbia. Four of these populations have apparently been extirpated. The remaining populations, ranging from 120 to approximately 40000 plants, are all northern disjuncts from the main range of this species. Threats to these populations include water level regulation and shoreline development. Considering the threats to the habitat of Lipocarpha micrantha, and the small size of most of the remaining populations, it has been designated an Endangered species in Canada.

Riverine Wetland

Off-channel habitats, such as wetlands and backwaters, are important for the productivity of river systems and for many species of native fish. This study aimed to investigate the fish community, timing and cues that stimulated movement to and from off-channel habitats in the highly regulated Lake Hume to Lake Mulwala reach of the Murray River, south-eastern Australia. In 2004–05, 193 712 fish were collected moving bi-directionally between a 50-km section of the Murray River and several off-channel habitats. Lateral fish movements approximated water level fluctuations. Generally as water levels rose, fish left the main river channel and moved into newly flooded off-channel habitats; there was bi-directional movement as water levels peaked; on falling levels fish moved back to the permanent riverine habitats. Fish previously classified as ‘wetland specialists’, such as carp gudgeons (Hypseleotris spp.), have a more flexible movement and life-history strategy including riverine habitation. The high degree of lateral movement indicates the importance of habitat connectivity for the small-bodied fish community. Wetlands adjacent to the Murray River are becoming increasingly regulated by small weirs and ensuring lateral fish movement will be important in maintaining riverine-wetland biodiversity.
