It seems to depend upon the system in regards to pH, streamflow, sunlight, and microbial activity. While we say that, in general, a sample is representative of what occurs up to 100m upstream, there have been records of DNA successfully traveling up to 3 miles downstream before being detected. However, eDNA traveling that far would be very rare and difficult to capture.
How far downstream from an organism can we detect the DNA? Print
