Planning an eDNA sampling project requires consideration of a number of different elements, including timing, sampling location, number of samples, filter type or precipitation method, sample volume, sample preservation, and lab analysis. The goals of the sampling or monitoring program will drive many of these decisions; for example, sampling location may be focused in a particular habitat in a lake if the objective is to detect a single rare species, or may be more widely distributed if the objectives is to describe aquatic communities of the entire lake. The resources on this page can help design a sampling strategy, select an analytical approach, and interpret results.
