Volume 7 - The phenology of selected Philippine mangrove species: A calendar
Mangroves offer numerous benefits. However, human activities and interventions within and near mangrove areas have led to the degradation of mangroves and the resources therein. Mangrove areas are converted into fishponds, saltponds, agriculture and coastal projects.
There is, however, a chance to renew the lost productivity of our mangrove areas. Mangrove plantations can be established and maintained. In establishing a mangrove plantation, a calendar on the phenology of selected mangrove species is most useful.
Phenology describes the recurring biological events, that is, budding, flowering and fruiting of plants in relation to seasonal climatic changes. The importance of phenology lies in the relation of seed or propagule production to nutrient enrichment, seed selection, treatment and nursery operation. Phenology makes one understand the effects of environment on plant development. Information on phenology helps growers analyze periodicity of plant development and biological organization of communities and ecosystems, composed of animal and plant interactions. These interactions affect pollination, seed dispersal and seed predation. This kind of information serves as a tool for local and global environmental monitoring. This type of data also benefits activities involving breeding program development and genetic centers.
This calendar on the phenology of selected mangrove species comes in handy form for easy use during fieldwork (original pamphlet). It highlights phenology dynamics wherein the time of budding, flowering and fruiting of each mangrove species in areas under four climatic types is indicated. Hence, this is a valuable reference in mangrove identification during field activities and for resource managers focusing on the rehabilitation, conservation and preservation of mangrove forests in difference areas in the Philippines. This shall serve as guide for farmers, foresters, researchers, students, managers, entrepreneurs and other groups interested in mangrove plantation establishment in both government and nongovernment sectors.©pangetgawavillaspin
