Mangroves provide habitat to many marine animals. These trees hold the ground, thus preventing erosion since there is a general tendency for the sea to engulf the land. The Tan Yan Kee Foundation, Inc. (TYKFI) recognizes the many other benefits of Mangroves aside from the ones mentioned. Thus, the Foundation, in partnership with the Municipality of Sta. Cruz, Ilocos Sur, launched “Las-Ud Mangrove Project” last August 14. 2014. It was attended by Hon. Teresita Valle (Mayor, Sta. Cruz, Ilocos Sur); Former DENR ASec Marlo Mendoza, Mr. Philip Sing, Ms. Elizabeth Alba, Mr. Jonathan Anuma, Ms. Valerie Tan and Ms. Janel Badlis ( Tan Yan Kee Foundation Representatives); Mr. Joseph S. Gumnad (OIC-Municipal Agriculturist) and Mr. Larry C. Calleja (AT/ MENRO); Mr. Antonio Lozano (Brgy. Captain, Las-Ud Sta. Cruz) and its Kagawad, Barangay Health Workers and member of 4P’s.
