New England's forests are a vital resource, providing habitat for wildlife, filtering air and water, and storing carbon dioxide. However, these forests are also facing a growing threat: hurricanes.
A recent study published in the journal Proceedings of the National Academy of Sciences has found that more frequent and intense hurricanes could have a significant impact on the ability of New England forests to store carbon.

They found that even a single hurricane could cause a significant release of carbon dioxide from the trees.
This is because hurricanes can knock down trees, which then decompose and release the carbon dioxide they had been storing.
The researchers also found that the impact of hurricanes on carbon storage would be greater in forests that are already stressed by other factors, such as climate change and insect outbreaks.
These findings suggest that New England's forests may be more vulnerable to the effects of hurricanes than previously thought.
For instance, the study referenced in this article found that a single hurricane in New England could down 4.6-9.4% of the total above-ground forest carbon.
This is a significant amount, especially considering that it takes approximately 19 years for downed carbon to become a net emission. The authors argue that current carbon market policies are not sufficient to account for the risks posed by hurricanes.
Here's a closer look at how hurricanes can impact forests' ability to store carbon:
Widespread tree mortality: Hurricanes can cause powerful winds and storm surges that can topple trees. When trees die, the carbon they store is released back into the atmosphere through decomposition. This can significantly reduce the forest's ability to sequester carbon.
Slow and long-lasting emissions: The release of carbon from dead trees is not immediate. It happens over several decades as the trees decompose. This means that the impact of hurricanes on carbon storage can be felt for many years after the storm has passed.
Increased vulnerability of stressed forests: Forests that are already weakened by other stressors, such as drought, disease, or insect outbreaks, are more likely to be damaged by hurricanes. This can create a vicious cycle, where hurricanes further weaken forests, making them more susceptible to future storms and reducing their ability to store carbon.
The study's findings highlight the need for new forest management strategies that take into account the risk of hurricanes. These strategies could include:
Planting more wind-resistant tree species: Foresters can prioritize planting tree species that are known to be more resistant to high winds. This can help to reduce tree mortality during hurricanes.
Forest thinning: Thinning forests involves selectively removing some trees to create more space for others to grow. This can make forests more resilient to wind damage by reducing competition for light and resources. However, it's important to balance thinning with the need to maintain forest health and biodiversity.
Creating buffer zones: Establishing buffer zones of trees along coastlines can help to protect inland forests from the worst effects of hurricane winds and storm surges.
Unfortunately, I couldn't find more information on new forest management strategies from the second link you provided, but browsing the first link provided more details on the impact of hurricanes on forests' ability to store carbon.
The findings of this study are important for policymakers, forest managers, and anyone who cares about the future of New England's forests.
By taking steps to protect these forests from the effects of hurricanes, we can help to ensure that they continue to provide us with the many benefits they offer.
