Water Net (Hydrodictyon Reticulatum)
Is a taxon of green algae that likes clear eutrophic water and has become a pest in New Zealand. Mats of this noxious aquatic algae can form extensive mats that clog stream flow and deplete oxygen levels through respiration at night time. As the mat grows the top layer can die and decay causing further depletion of stream oxygen levels. Water net is commonly found in open stream environments that lack riparian cover.
Glasswort – Sarcoconia Quinqueflora
Is a species of succulent halophytic (salt tolerant) coastal shrub commonly found in wetter coastal areas of New Zealand.
