Abstract | Trees provide shelter, release oxygen, absorb carbon dioxide, and reduce temperature in urban park. However, tree mortality leading to its falling can be dangerous and can be a caused is by wood-decaying macrofungi (WDM). They destroy heartwood and sapwood by releasing enzymes to decompose wood components. There are many species of WDM and each species causes wood destruction to varying degrees. Thus, the aim of this study was to find species of WDM causing catastrophic failure in tree structural integrity and to perform a risk assessment in Lumphini park, Bangkok, Thailand. Within a total of 276 trees surveyed, 33 WDM specimens were found on 21 trees. They were identified under 16 species, two genera (Ganoderma and Phellinus), two families, two orders, one class, and one phylum. Ganoderma was the most frequently found WDM in this study, accounting for 67% of all specimens. Tree risk assessment revealed that the overall risk at Lumphini park was low. The highest failure was found on trunk. The likelihood of tree failure was significantly different (p<0.001) between different tree species. Casuarina jughuhniana had the highest likelihood of failure, followed by Acacia auriculiformis and Delonix regia, respectively. Ganoderma caused more tree failure than Phellinus. Moreover, the occurrence of WDM on any trees indicated that the likelihood of tree failure was higher than the trees without WDM. |
