The Department of Environment and Natural Resources (DENR) has identified about 53 cave areas in Central Luzon and urges the public to protect and conserve these resources, which serve as home to important animal species and potential ecotourism site, environment officials announced yesterday.
Paquito Moreno, Jr., regional director of DENR-Region 3 said caves are critical part of an ecosystem which is rich in biological, historical and geological resources.
“Central Luzon is rich in caves. This natural ecosystem is one of the wonders of nature and part of our natural heritage. It is usually hidden in the mountains and exhibit awesome rock formations of stalactites and stalagmites,” he explained.
He said caves must be protected and sustainably managed as it contains valuable natural resources which can provide numerous educational, historical, cultural, economic, scientific and aesthetic benefits to our communities.
According to Arthur Salazar, deputy director for Technical Services, caves are home to some important species of frogs, bats, mammals, birds, reptiles, crabs and even microorganism.
“This unique ecosystem also contains specialized mineral formations, including calcite, limestone, and gypsum,” he said.
He said out of the 53 identified caves in the region, 27 of these can be found in Bulacan, ten are in Nueva Ecija, eight in Zambales, six in Aurora and two are in Tarlac.
The DENR has also officially classified eight caves in Aurora and Bulacan into Class 1 and 2, which are now being managed by the local government units (LGU), he added.
These caves are Sinag, Tikbalang and Layang-layang caves, all in San Luis town in Aurora; Puning cave in Dona Remedios Trinidad town, Bayukbok, Pebbles and Madlum caves in San Miguel town, and Pinagrealan cave in Norzagaray town, all in Bulacan.
According to DENR cave classifications, class 1 caves are those with delicate and fragile geological formations, threatened species, archeological and paleontological values, and extremely hazardous. Allowable use may include mapping, photography, educational and scientific study.
Class 2 are those caves with areas or portions which have sections that have hazardous conditions and contain sensitive geological, biological, archeological, cultural, historical, and biological values or high-quality ecosystem. It may be necessary to close sections of these caves seasonally or permanently. It is open only to experienced caves or guided educational tours or visits
Class 3 are caves generally safe to inexperienced visitors with no known threatened species, archeological, geological, natural history, cultural and historical values. These caves may also be utilized for economic purposes such as guano extraction and edible birds nest collection.
“We urge the public especially those cave enthusiasts, mountain climbers and eco-tourist to protect and conserve our cave areas in the region because this is one of our pride and natural heritage,” Moreno said.
