Lakes

Three plants of an endemic submerged quillwort (Isoëtes) were recovered from Lake Ōmāpere by NIWA in 1998, prior to the lake weed (Egeria densa) dying off and the lake switching into an algal dominated turbid state. No further isoëtes plants have been observed in the lake since that time.

The ability to properly manage our freshwater resources requires a solid understanding of the flora and fauna which live in and interact with them.

John Clayton, a principal scientist in the fields of aquatic biodiversity and biosecurity based at NIWA's Hamilton office, has won a 2011 Kudos award for his leading role in the development of LakeSPI  (Lake Submerged Plant Indicators).
