eDNA

Between 2023 and 2025 Living Landscapes undertook a comprehensive eDNA survey with catchment groups we work with. 

eDNA measures of the life supporting capacity of water, or the cumulative impact of:

​

• What is happening now (e.g. nutrients, sediment, stock access); 

• Past changes (e.g. land drainage or removal of native forest), and; 

• Actions of nature (e.g. weed invasion or low flows). 

​

eDNA helps determine priorities and benchmark changes over time. It can also detect rare or valued species such as tuna (longfin eel), kanakana (lamprey), koura (freshwater crayfish), or freshwater mussels.
