Recently in Southern Utah it has come to the attention of many ecologists that the tree species, whitebark pines, is on the cusp of becoming an endangered species due to climate changes and droughts in the south. As a quick solution, some members of the scientific community have suggested “assisted migration” whereas humans would restore the whitebark pine population by dispersing its seeds from areas of the hot south to more adaptable, cooler weather up north.
To put this proposition to the test, graduate student, Sierra McLane, under Dr. Sally Aitken of the University of British Columbia, conducted a study and spread the seeds of whitebark pines throughout much cooler and consistent weather of the British Columbian mountain ranges. As a result, 20% of the seeds germinated and continue to grow here, allowing McLane to affirm that whitebark pines would successfully grow in the colder climate.
Despite her evidence, McLane, along with many other scientists’ “assisted migration” is bound more by an ethical dilemma than biological. Although it is clear that these whitebark pines are a crucial species to provide animals, like bears and birds, with food and shelter, some scientists are skeptical over how easily these animals will be able to adapt to the change in their location and others are morally conflicted over whether humans should interfere with nature thus changing the future. While assisted migration continues be deliberated by scientists as a possible solution to the threatened whitebark pine tree population, what is your attitude on the subject? Do you believe it is our moral responsibility to “take care” of the environment or should we not interfere with the natural selection of wildlife?
