Trees provide products and services necessary for human existence and survival. However, many of the trees are subjected to stress factors and are often neglected especially those century - old trees which could have historical and cultural values. If not checked earlier, defects in trees could turn into menace. Health assessment and rehabilitation are important to extend tree life and bring back its beauty and form.

Thus, the Ecosystems Research and Development Bureau (ERDB) team composed of Forester Cecille Quiambao-Marquez, Mr. Jose Anicete, Mr. Gilbert Buenaobra, and Mr. Jay Senson of the Laboratory and Experimental Services Division conducted a tree risk assessment and rehabilitation of a century old duhat tree in Rizal Park, Luisiana, Laguna.

Accordingly, the tree used to be a resting place of katipuneros. An 83-year old man could still remember when he was an elementary grade pupil, he and his classmates used to climb the tree to harvest its fruits. Even until now, it is observed that the tree still bears fruits and at the same time provides shade to people.

However, as per ocular inspection, the tree has been subjected to stress factors: patches of bark have been removed because bark decoction is being used to wash wounds, skin ulcers, and taken in to cure diabetes and diarrhea; rope was tied and served as posts; presence of nails and epiphytic plants; concrete pavements over the roots; and garbage and cigarette butts inside the trunk opening. The damage done on the trunk can result in an entry point for decays and over time can cause death of a tree. Cecille Q. Marquez, LESD
