Impact of Rising Sea Levels on Coastal Trees

Dendrochronology:
The study used dendrochronology, which examines tree rings to correlate growth with environmental conditions.
Gradient-boosted linear regression, a machine-learning model, was used to assess the combined effects of temperature, precipitation, and tidal water levels on tree growth.
  • Global warming is raising sea levels and increasing flooding, affecting the growth of coastal tree species.
  • While previous research suggested these factors negatively impact tree growth, a new study finds intriguing insights.
  • Rising sea levels and coastal flooding can enhance resilience in some coastal trees but harm others. Species like the American holly showed improved growth in response to more water, while loblolly and pitch pine trees suffered.
  • Factors Affecting Tree Growth:
  • Temperature
  • Rainfall
  • Soil health
  • Proximity to water.
  • Coastal trees are moving inland due to rising sea levels, but they face new challenges in these environments.
