The health of the trees in the dehesa is one of the fundamental pillars for ensuring the sustainability of this valuable ecosystem. The holm oaks and cork oaks, essential trees for the dehesa, face a series of challenges that threaten their survival, such as disease, climate change and the lack of natural regeneration.
Main challenges for the health of the trees:
- Diseases in the woodland: Pathologies such as drought affect the vitality of the holm and cork oaks. The lack of natural regeneration and the weakening of the trees due to these diseases compromise the ecological balance of the dehesa.
- Climate change: Extreme drought conditions, intensified by climate change, hinder the regeneration of trees and put their growth at risk.
- Loss of species diversity: The lack of adequate regeneration or the monoculture of trees can reduce biodiversity in the dehesa, affecting the stability and functionality of this ecosystem.
Proposed solutions to improve the health of the trees:
✅ Promotion of natural regeneration: It is crucial to promote the natural regeneration of trees through the control of competing species and the protection of young shoots. In addition, controlled plantations should be carried out to ensure the replacement of old trees.
✅ Pest and disease control: Implementing integrated management strategies is key to controlling pests and diseases that affect trees, guaranteeing their long-term health.
✅ Innovation in forest management: The use of innovative technologies, such as remote monitoring, allows for the early detection of tree health problems and the effective application of the necessary interventions.
The regeneration and health of the trees are essential not only for the well-being of the local biodiversity, but also for the water cycle, carbon capture and other fundamental ecosystem services. Without proper woodland management, the sustainability of the dehesa is at risk.
