A new form of biodiversity monitoring

Air quality stations have collected vast stores of DNA by accident, a potentially ‘game-changing’ discovery for tracking global biodiversity – ScienceDaily

I expect that it has its biases, such as detecting the presence of wind-pollinated plants quite remote from the station. I wonder if people can stop counting pollen grains in air samples.

Very interesting, was thinking about edna monitoring this morning in terms of meadow plants and other organisms. One of the biggest issues is understanding what it means, I suspect this will be an even bigger issue for that particular kind of sampling.
