Lalaguna Marsh


Lalaguna Marsh is near the southernmost tip of Lamon Bay in Quezon Province. It is an inland freshwater marsh with dense reed beds and an abundant growth of other aquatic vegetation. The maximum depth of the water is 3 m. During the dry season (February-April), the water level recedes and about one third of the marsh dries out. Some boat navigation is possible in cleared areas. The marsh provides an important source of fish for local inhabitants, and supports a small reed cutting industry for basket making and mat weaving. There are coconut plantations, rice paddies and residential areas around the marsh.

The dominant aquatic species are Scirpus grossus, Eichhornia crassipes, Ipomoea reptans and Phragmites communis also known as club-rush, water hyacinth, water/river spinach and the common reed respectively.  Coconut plantations and rice paddies are found in surrounding areas.

Unfortunately, threats or other danger is inevitable in every paradise (discovered / non-discovered) here in the Philippines and I've read that this place is not protected by lawmakers. uncontrolled shooting and trapping of waterfowl, especially ducks and rails, is having a detrimental effect on the populations, and dogs from nearby residential areas cause considerable disturbance to nesting birds. A proposal has been made to stock the marsh with exotic species of fish, and this could pose a threat to the native fish fauna. The clearing of old coconut plantations in the water catchment area has resulted in severe soil erosion and this has led to an increase in sedimentation in the marsh.
