Agochory
As Agochorie refers to the unintentional spread of plants by humans. Agochory is next to Ethelochorie and Speirochorie a sub-form of Hemerochorie , the spread of plants by humans.
On land, agochore plants used to be common in harbors, at train stations or along railway lines. Investigations on cars with which tourists wanted to enter the Australian Kakadu National Park , however, show that automobiles are also significantly involved in the agochoric spread: 70% of the vehicles examined carried plant seeds, including seeds, in the tire grooves or in mud deposits on the chassis a number of such plants, which are classified as problematic invaders in Australia and which one would like to keep away from the park, which is part of the world natural heritage .
However, mainly aquatic plants with ballast water are spread worldwide through agochory . Countries like Canada , Australia , the USA , Chile and Israel consider this form of spread to be so serious that they are making efforts to make the handling of ballast water internationally binding. Plants carried by agochorus have caused serious disturbances to the coastal fauna and flora in all these countries, which have also caused major economic disturbances.
