What created the skeleton forests found in prince edward island national park?

In the early 20th century, a massive infestation of spruce budworm caterpillars defoliated the balsam fir trees in Prince Edward Island National Park. The caterpillars ate the needles of the trees, leaving them bare and vulnerable to the harsh winter weather. As a result, many of the trees died and their skeletons remain standing in the park today.

The spruce budworm infestation was caused by a combination of factors, including a lack of natural predators, favourable weather conditions, and the introduction of non-native tree species. The infestation reached its peak in the 1940s and 1950s, and it caused widespread damage to forests across eastern Canada.

The skeleton forests of Prince Edward Island National Park are a reminder of the destructive power of insect infestations. They also serve as a reminder of the importance of maintaining a healthy and balanced ecosystem.
