This scientist shoots trees to study how they migrate
In Black Rock Forest, just north of New York City, Angie Patterson aims a shotgun at a northern red oak tree. Patterson is a plant ecophysiologist, and the leaves that she’s shooting out of the canopy will give her data to understand how and why trees migrate.
Trees have been on the move since at least the last ice age. As their native habitats become inhospitable, tree ranges shift, slowly, to areas they can thrive. But climate change is disrupting the process, scientists say. As of 2019, the IUCN Red List categorized more than 20,000 tree species as threatened, and upward of 1,400 as critically endangered.
As scientists scramble to learn more about what drives tree migration, others are planning for the future. To preserve biodiversity, both citizens and researchers are employing interventionist tactics once steeped in controversy like “assisted migration” — taking tree seedlings and planting them in new locations. Rising global temperatures may force wildlife agencies and forest managers to decide what to save and what to leave behind.
The Verge Science video team trekked into the woods with “the shotgun scientist” to learn how and why trees move to new locations. Can we do anything to help the trees? And what tough calls will we have to make if we can’t? Watch our latest video to see what we discovered.
