Tree health is a research area focused on studying the overall well-being and vitality of trees in forests, urban environments, and other ecosystems. This research involves monitoring the physical health, stress factors, diseases, pests, and environmental conditions that can impact tree growth and survival. It also involves identifying strategies for promoting tree health, such as proper tree care practices, pest management techniques, and conservation efforts. Tree health research is important for maintaining the ecological balance of ecosystems, preserving biodiversity, and ensuring the long-term sustainability of tree populations.
