Dan­ger of ali­en plant spe­ci­es

Intro­du­ced plant and ani­mal spe­ci­es can crea­te eco­lo­gi­cal desas­ters. Ali­en spe­ci­es have alrea­dy been found in many parts of the polar regi­ons, inclu­ding Ant­arc­ti­ca. In more recent times, the hig­hest risk of intro­duc­tion is use of con­ta­mi­na­ted boots that have been used else­whe­re, pos­si­b­ly in cli­ma­ti­cal­ly com­pa­ra­ble high moun­tain or polar are­as.

In 2008, sci­en­tists have tes­ted boots of 260 visi­tors at the air­port in Lon­gye­ar­by­en and found 500 moss frag­ments and 1000 seeds of 52 plant spe­ci­es, inclu­ding many birch seeds.

Not just a rub­ber boot, but a poten­ti­al­ly dan­ge­rous source of con­ta­mi­na­ti­on
