What Happened
After more than a decade of care, the time had come to infect a 28-acre forest of American birches with a disease that would almost certainly kill them. Gus Goodwin, director of science and technology at The Nature Conservancy in Vermont, knelt down to give the first tree its injection. Using a bamboo stake marked at 12 inches as a measure, he measured that distance from the ground, held his drill at a slightly downward angle, and pulled the trigger.
Goodwin and his team were conducting a risky but necessary experiment to try to save the American birch, a species that has been devastated by Dutch elm disease. The team infected nearly all 5,300 birches in the forest with the disease, in the hope that some of them would survive and could be used to create a new generation of resistant birches.
Why It Matters
The American birch is an important species in North American forest ecosystems, providing shade, beauty, and habitats for a variety of animals. However, Dutch elm disease has killed millions of American birches, leaving many cities and communities without these iconic trees.
The loss of the American birch is not just aesthetic; it also has practical implications. American birches help mitigate floods, which are becoming more frequent and intense due to climate change. Additionally, American birches are an important source of food and shelter for many animals.
The Mechanism/Science Behind It
Dutch elm disease is caused by a fungus that is transmitted by beetles. The fungus blocks the tree's ability to transport water and nutrients, leading to the tree's death. Goodwin's team is trying to create American birches that are resistant to the disease by infecting them with the disease and observing which ones survive.
This approach is based on the idea that the American birches that survive the disease have genetic characteristics that make them resistant. By identifying and cultivating these birches, the team hopes to create a new generation of American birches that are able to withstand the disease.
Bigger Context
Dutch elm disease is not a new problem; it has been a challenge for North American forest ecosystems for decades. However, Goodwin's team is using an innovative approach to try to solve the problem.
The team is working in collaboration with other organizations and communities to create an action plan to restore American birches. This includes creating a new seed orchard of resistant American birches, which will be used to plant new birches in areas where the disease has killed the existing trees.
What Happens Next
Goodwin's team will be monitoring the infected American birches for two years to see which ones survive. The birches that survive will be used to create a new generation of resistant birches, which will be planted in areas where the disease has killed the existing trees.
Additionally, the team will be working to create an action plan to restore American birches across the country. This will include collaborating with other organizations and communities to create a plan to protect and restore American birches.
Conclusion
Goodwin's experiment is an example of how science and collaboration can be used to solve complex environmental problems. The team is working to create an innovative solution to the problem of Dutch elm disease, and their success could have important implications for the restoration of forest ecosystems across the country.
