Wilderness Landscape & Natural Heritage
Located near Puerto Princesa on the island of Palawan, the Iwahig River Mangrove Forest encompasses a sprawling area of mangrove wetlands that thrive along the lower stretches of the Iwahig River. This forest is part of the larger Palawan ecosystem, a globally recognized biodiversity hotspot. The mangroves provide essential nursery grounds for fish and crustaceans, stabilize shorelines against erosion, filter pollutants, and act as carbon sinks, mitigating climate change effects. Ecologically, it supports a diverse range of flora and fauna including various mangrove tree species such as Rhizophora and Avicennia, numerous bird species like kingfishers and herons, and aquatic life such as mud crabs and fish. Historically, the forest has been integral to the local community for subsistence fishing and gathering, with traditional knowledge shaping sustainable interactions. Visitors to the Iwahig River Mangrove Forest can experience guided paddle boat tours through the serene waterways, bird watching, and educational nature walks, allowing for an immersive encounter with this unique coastal environment. The forest’s proximity to Puerto Princesa, combined with its tranquil natural setting, makes it an appealing destination for eco-tourists and conservationists. Efforts to protect this area focus on controlling illegal logging, mangrove reforestation, and engaging local custodians in sustainable practices to preserve its ecological integrity for future generations.
