Dear Mr Simon ,
Good Day
Bajo National Park features multiple biomes and a complete ecosystem ; beach vegetation ,cliff vegetation ,heath forest ,mangrove forest, mixed dipterocarp forest , grassland vegetation and peat swamp forest. This are documented by Sarawak Forestry Department as well as variety of carnivorous plants. This is the best place to see species endemic to Borneo, but like many wildlife they shy away.
For the exemption of the animals that hang-out at the cabins/park entrance , greeting our arrival and also looking out for their species if we are a treat. Although we would like a close-encounter with the many species of animals, not being able to spot them on the hiking trail is a good indication, the animals are not dependent on humans. My apologies on the trash during your visit, this needs to be address by park management. A National Park fee is imposed for all visitors which goes to the upkeep of the park. No reason for those plastic trash. Tidal waves bring in ocean plastic waste, washout on our beaches and adjoining mangrove area's. No any amount of explanation can resolve except to clean the plastis waste and prevent any animals from consuming or from monkey's taking it as souvenir's , preventing the monkey's from recognizing that plastic bottles are a source of tasty treats.
