Reaction Paper on Mangrove Rehabilitation Project

“Reaction Paper on Mangrove Rehabilitation Project”

September 3, 2011, the History Department of Mindanao State University had a Mangrove Rehabilitation Project, a propagule planting at Sittio Bayug, Hinaplanon, Iligan City. 6:00 am in the morning we already go off with the History faculty and students in the mangrove sanctuary at sittio Bayug. There, we have to travel through a boat to cross over the island; the fare cost 3php (pesos). One mangrove propagule cost 4php (pesos), though we really have to plant these propagules in the mud, a little bit mud-spattered experience for the first time. Mangrove planting was very essential because the contribution of mangrove forest for coastal stability and protection was highly recognized in the recent times. Naturally occurring in the estuarine areas of tropical and subtropical regions, mangrove forests display a high efficiency for sedimentation and wave attenuation. The high complexity of the root system, dense stem, and canopy covers interact with current and tide properties to create such effects. Recently, mangroves have not been considered anymore as “land-builders”, thus colonizing only areas that are suitable for growth. The wave reduction potential of mangrove forests has been seen as highly efficient if certain conditions are satisfied such as density and height of the mangrove forest, the diameter of mangrove roots and trunks, and canopy density. Knowledge on the tidal properties in the area is also important. The species of mangrove planted or the width of the mangrove forest might be too small to reduce effectively the given waves in the area.

The concern must also be raised with regards to the use of mangrove species that are not naturally occurring in an area because they might act as invading species. Since Estuarine conditions are suitable for mangrove growth; they have high potential to outcompete native species leading to their displacement. Introduced mangrove species might also carry other species of organisms that have the potential to become pests due to the absence of natural predators in the new environment. It is recommended that mangrove species naturally existing in a particular place must be used instead of using exotic species. It is also important to allow the mangrove forest to respond naturally to their environment especially in response to sea level rise wherein man-made structures landward from the mangrove might hinder their retreat.

The experience was priceless, it was fun and yet a fulfillment on my part because it was my first time to plant a tree. Well, we should be cognizant and have to take a look at what small things can do for the sake of our environment.
