What does El Nino mean for tree care in the Hudson Valley?

As the winter of 2023-2024 approaches, the forecast by the NOAA Climate Prediction Center is that an El Niño winter is coming. In Ulster, Dutchess, Columbia and Greene County, the Hudson Valley and Catskills region, and the Northeast as a whole, we must examine what the implications may be for the health of our trees and the safety concerns that may emerge.

It is true that El Niño may cause warmer than normal temperatures this winter, which could result in less heavy snowfall. However, it could also be a drier winter than usual.

Dryer and Warmer Winter: A Challenge for Trees in the Hudson Valley

A dry and warm winter presents the following challenges to our local trees:

  1. Less soil moisture:  Trees rely on moisture in the soil to sustain them through the winter. Dryer conditions can translate to scarcer soil moisture, which can lead to stress and negatively affect tree health.
  2. Pest and disease vulnerability: Dry conditions are a favorable environment for pests like ash borers, ageldids, hemlock scales, mites and diseases to thrive. Trees already weakened by moisture stress are more susceptible to these threats, increasing the risk of infestations and infections.
  3. Reduced cold weather insulation: Soil moisture acts as an insulator, helping to maintain a healthy soil temperature during particularly cold conditions. Without a protective layer of moisture, more sensitive trees may suffer cold damage, potentially leading to tree death.

How can Tree Services Help?

The dryer and warmer winter forecasted during this El Niño year can have several implications for companies like ours that offer tree services in the Hudson Valley and Catskills:

  1. An increased need for pruning: Trees that have experienced  stress and pest infestations may need extensive pruning to remove damaged and diseased branches. Pruning helps improve tree health and structure and prevent worse outcomes from developing.
  2. More tree removal: When trees are severely stressed, infested, or at risk of falling due to structural issues, tree removal may be necessary for safety reasons.
  3. Cabling and bracing:  To protect vulnerable trees from structural failure during heavy snow or ice events, cabling and bracing services may see increased demand as tree owners seek to safeguard their valuable assets.
  4. Emergency response: When a storm does come, the existing stressful conditions may increase the need for emergency services for trees.

Preparing for the El Niño Winter

In anticipation of the challenges that this El Niño winter may bring, it’s essential for tree owners and communities to take proactive measures before an emergency occurs.

  1. Hydration: Water your trees, especially during dry spells. This can help mitigate moisture stress and maintain tree health.
  2. Pruning and Maintenance: Pruning and other routine maintenance services can help prepare trees for the winter months and reduce potential risks
  3. Emergency Plans: Develop emergency response plans in case of extreme weather events, including access to tree removal and clearance services.

The impending El Niño winter, with its forecasted dryer and warmer conditions presents challenges for trees and ecosystems in Northern regions. As trees face increased stress and vulnerability to pests and diseases, the demand for tree services like pruning, removal, cabling, and emergency response may rise. It’s crucial for tree owners and communities to stay vigilant, take preventive measures, and be prepared for potential tree-related issues during this unusual winter.
