The University of Puerto Rico Sea Grant Program understands the need to have an educational tool to aid instructors during the teaching-learning process regarding the marine and coastal resources of the Puerto Rican archipelago. With this goal in mind, we have taken it upon ourselves to produce this Educational Guide about Mangrove Forests which includes a CD, this student handbook, a story book and an activity book. We hope this manual will prove useful when teaching about our marine and coastal resources and likewise foster in our youth a deeper appreciation for this ecosystem, motivating them to promote its conservation and protection.
