Genetic diversity is an important component of biodiversity. Recent NIWA research shows how contaminated stormwater can reduce the genetic diversity of one model freshwater species.
Beds of New Zealand seagrass (Zostera muelleri) provide important habitat for coastal species such as small fish, seahorses, and shellfish. Much of New Zealand’s seagrass habitat has been lost or degraded, mainly as a result of sedimentation. NIWA is leading a small-scale seagrass transplantation trial in Whangarei Harbour, with promising early results.
