The study examined the diversity of pasture vegetation at Texas Tech University in the United States by detecting eDNA in the air, and compared it with traditional survey methods. It was found that eDNA technology could detect more plant species than traditional methods, especially some short grasses and some grasses with smaller flowers. These types of vegetation are often not easily spotted in traditional surveys. Studies have shown that eDNA technology greatly reduces the cost of surveys, and can be used as a time-saving and labor-saving method to monitor environmental vegetation diversity with seasons and the detection of invasive plant species for a long time.
