A Window of Resurgence for Red Spruce
Update: 2020-05-14
Description
In the 1970s, red spruce was the forest equivalent of a canary in the coal mine, signaling that acid rain was damaging forests and that some species – especially red spruce – were particularly sensitive to this human induced damage. In the course of studying the lingering effects of acid rain, scientists came up with a surprising result – decades later, the canary is feeling much better.
