Maine researchers explore hybrid green ash and assisted migration for climate resilience

During a recent Infrastructure Committee meeting in Bangor City, discussions centered on innovative strategies to combat the challenges posed by the emerald ash borer and climate change on Maine's forestry. The committee is exploring the potential introduction of hybridized green ash trees that exhibit resistance to the invasive pest, although research in this area is still in its early stages.

The committee acknowledged that the introduction of these resistant trees would be a long-term solution, likely implemented after the initial management of affected ash populations. This approach aims to mitigate the impact of the emerald ash borer, which has caused significant mortality among ash trees in the region.

In addition to hybridization efforts, the committee is considering the concept of assisted migration. This involves planting tree species from southern New England that are better suited to warmer temperatures, as climate change continues to affect local ecosystems. By introducing these species, the committee hopes to ensure that Maine's forests remain resilient in the face of rising temperatures.

The discussions highlighted the importance of selecting the right species for specific locations, emphasizing a thoughtful approach to reforestation that considers both ecological compatibility and future climate conditions. As the committee moves forward, these strategies could play a crucial role in preserving Maine's forestry and biodiversity in the coming years.
