Backcross: Tree Species Restoration & Resistance Breeding

In season one of Forestcast, entomologists showed us the ways we slow insects from attacking and killing trees. This season, we’ll meet another set of scientists, scientists who have been attacking the issue of non-native invasive insects and pathogens from a different angle. Chemicals and biological control can buy trees time, but they cannot completely control the non-native insects that are attacking trees that have never experienced these insects before. We need something on top of those controls, and these scientists, they’ve been working towards a solution — a long-term resistance. What is it? Well, it’s simple. At least, a simple idea: use trees.
