The use of eDNA and DNA-based methods to assess and monitor alien and doorknocker species

All organisms that interact with an environment leave traces of their genetic material in some form. This DNA/RNA can be used to assess the presence of species using a variety of molecular tools and can potentially be part of an effective early warning system for alien species.

This report, commissioned by the Norwegian Environment Agency, aims to present an overview of methods using eDNA to detect and monitor alien species.

This report is based on an initial commissioned project from the Norwegian Environment Agency to a consortium of Norwegian institutions (2021) where background literature on this topic was assembled and made available for future assessments.
