Long Island’s Trees Face an Unprecedented Climate Crisis: Your Property Could Be Next
Climate change is fundamentally altering the landscape of tree health across Long Island, creating conditions that threaten both the natural environment and homeowners’ most valuable assets. Severe Drought (D2) conditions continued for most of southern New England, southeast New York, and Long Island throughout 2024, marking one of the most challenging years for tree survival in recent memory.
The Perfect Storm: Drought, Heat, and Vulnerable Trees
Long Island experienced a particularly devastating drought in 2024, with the East End of Long Island in a D2 category drought, which translates into a severe drought, and is now in the D1 category, or moderate drought. This prolonged dry period has created cascading effects throughout the region’s urban forest. Most places are still in a 6- to 9-inch precipitation deficit, leaving trees struggling to access the water they need for basic survival.
In New York these changes include higher temperatures, more frequent and intense storms year-round, more rain in the winter, more frequent summer droughts, and higher sea levels. These changing conditions are particularly harsh on Long Island’s trees, which must now contend with extreme weather swings that stress their root systems and compromise their natural defenses.
When Trees Fight Back: The Wildlife Connection
The drought has created unexpected challenges for homeowners beyond just tree health. Drought also influences our wildlife, which then has an effect on our gardens. Deer and rabbits are finding less and less browsable growth simply because the drought has stopped or stunted the growth of the plants they might feed on in the wild. As a result, these animals and others will seek out our gardens and shorter trees and shrubs as sources for food.
This means that stressed trees are not only fighting environmental conditions but also facing increased pressure from hungry wildlife seeking alternative food sources.
The Hidden Threat: Climate-Enhanced Pests and Diseases
Climate change has created ideal conditions for tree pests and diseases to thrive. Climate change often makes trees even more susceptible to damage from insects and disease, which reduces a forest’s ability to sequester carbon. Research shows that forests damaged by insects sequestered 69% less carbon than undamaged forests. Those affected by disease sequestered 28% less carbon.
Several invasive species pose particular threats to Long Island trees. Ash, beech, elm, and hemlock—some of North America’s most iconic tree species—are dying from pests and diseases. The emerald ash borer has been particularly devastating, while beech leaf disease in more than 90 communities since it was first discovered in the state in 2020 continues to spread throughout the Northeast.
Hotter summers with more dry periods will be particularly problematic for northeastern US forests, because these conditions stress trees, which can increase survival and population growth of pests that specialize on weakened or dying trees. These insects and pathogens, often termed secondary pests, may become more serious pests in the future if more stressed trees appear on the landscape.
What Homeowners Need to Know Right Now
The 2024 drought has lasting implications for tree health in 2025 and beyond. Watch the stems and branches, especially on fruit trees to see the annual growth on these tree parts to gauge against a “normal” year’s growth, and if you have an arborist who works on your property ask him or her to show you the 2024-25 growth and if it’s normal or stunted due to the drought.
Property owners should be vigilant for signs of tree stress, including:
- Reduced leaf size and premature leaf drop
- Stunted branch growth compared to previous years
- Increased susceptibility to pest infestations
- Crown dieback and dead branches
- Root damage from prolonged dry conditions
