Most of the lands are planted to coconuts and fruit-bearing trees and ideal pasture land for livestock.  The coastal areas are dotted with alternating rocks and white beaches.


  • The Zamboanguita sandy loam is the major soil type in the locality which is suitable for vegetables, rice, coconuts, fruits and root crops.


  • The climate of Corcuera falls on type II with a long summer usually from November to April accompanied by northeasterly winds or Amihan.  The rainy season is from May to October usually accompanied by the southwest monsoon or the Habagat as the locals call it.


  • Suba Bay, a 28 hectares body of water with an outlet which could be fenced and developed for fish, prawn and shrimp culture located between Mabini and San Roque.  It can also be an ideal site for the establishment of a canning industry now that electric power is available.
  • There are also two (2) creeks located at Colong-colong which can be sources of water for agriculture through the construction of water impounding dams or reservoir.

  • Three hundred sixty-three (363) hectares are presently used for the production of lowland crops such as rice and corn and one thousand seven hundred ninety-nine (1,709) are planted to upland crops such as coconuts, bananas, vegetables and fruit trees. Thick mangroves constitute the 36 hectares of marsh land in Suba Bay.
  • Pasturing is done in the lowland areas after the harvest of rice, corn, and other crops.  It is also done under the coconut trees because there is no available land for grazing of cattle, goats and other animals except in idle land which are just small portions.
  • From a distance, a quick glance of Simara shows that it seems to be teeming with plantations.  But in reality agricultural productivity is low because of the lack of irrigation and lack of large bodies of fresh water.
