Disease Infestation and Insect Damage of Pygmy Trees inMount Hamiguitan Range Wildlife Sanctuary

A study of pygmy trees in Mount Hamiguitan Range Wildlife Sanctuary revealed that fungal diseases were the dominant cause of internal infections, significantly impacting plant health. The research found severe damage at four stations, primarily due to insect infestations and bacterial contamination, with leaves being the most commonly affected part. Symptoms included leaf scratches, black spots, red lesions, and wilting. The study employed a transect walking method across 10 stations, examining three replicates of tree species per station for detailed analysis in the laboratory.
