Biophysical conditions of caves in Mabinay, Negros Oriental [Philippines] assessed for ecotourism promotion

One form of ecotourism is caving and this is being developed on the island of Negros specifically in Mabinay, Negros Oriental. The increase in the number of untrained cave explorers visiting the caves of Mabinay prompted the municipality to develop easy means of access to the caves. Walkways and pathways were constructed for the visitors, however, the construction of such structures were not subjected to an environmental impact assessment. Tababa et al. (NSCA) undertook a study in November 2006 to determine the conditions of the caves in terms of their viability as ecotourism destinations. The study also determined impacts on the cave environments as a result of infrastructure development and cave visits. Findings of the study revealed the following: Five caves, promoted for ecotourism in Mabinay, Negros Oriental, were studied by the researchers. All were used by bats as roosting sites but were disturbed by hunting and cave activities. At least 11 species of bats were found in the study areas. These included five species of bats belonging to the suborder Megachiroptera (fruit bats) and six species belonging to the Microchiroptera (insect eating bats). The cave habitat with the most number of bat species observed was Mambajo cave (nine species) while Crystal and Pandanihan caves had the least number of species observed ( 1 species each with few individuals). Three adjoining caves out of five caves were identified as ideal caving destinations for moderate cavers. One cave was recommended for extreme caving activities and another one was a special cave destination for bat habitat viewing. The study recommended improving the current cave tourism program. This included promoting cave habitat protection in caves known to be inhabited by important species of bats such as Mambajo cave. This was used to be inhabited by the rare Negros barebacked fruit bat and presently inhabited by thousands of nectar-feeding bats. Advocacy for local policy legislation to protect cave habitats and promote conservation of bat species was also recommended. This should include full implementation of the Wildlife Act and Cave Laws.
