Climate change is intensifying the spread and severity of biotic stressors, altering the interactions between trees and pathogens, and increasing the vulnerability of many species across both urban and forest environments. In this scenario, it becomes crucial to assess how trees already affected by biotic agents respond physiologically not only to environmental conditions but also to treatments aimed at mitigating stress.

IoT-based sensing technologies enable continuous, non-invasive monitoring of key parameters such as sap flow, radial growth, and microclimatic conditions. These high-resolution data allow the real-time analysis of physiological responses related to biotic stress and treatment effects, offering new insights into the combined impacts of climatic and pathogenic factors.

This presentation will showcase several case studies where these technologies were applied in forest and urban settings to evaluate the effectiveness of post-infection treatments and to better understand tree responses under complex stress conditions.
