Environmental DNA or eDNA is a modern method for confirming the presence or absence of an aquatic or semi-aquatic species. It is based on the detection of eDNA left behind by an organsims. It is very sensitive thus less prone to false negative results of the old catch and identify the animal methods. It is also more specific and reduces the risk of mixing up species as current visual methods do.
Biologist are attached to old methods they know. Modern science is better for monitoring species at risk, because it is more reliable, faster and costs less that the old methods. Yet, there seems to be resistance to abandon the comfort of old methods and move to modern science. Lack of reliable data is at the core of fuzzy monitoring of species at risk.
Therefore the speceis at risk act that clearly and non equivocally states that environmental DNA should be used, when possible, to provide better.
