Sta. Maria, sprawling under the southern blue skies of Davao del Sur, is a span of 22, 489 hectares of verdant forest, arable lands, beautiful beaches with white sand, cascading waterfalls, brackish waters, natural fish sanctuaries, winding streams and diverse flora and fauna. It is inhabited with a number of tribes that bonded together into a small community of persons. Majority of the people are from Tagakaolo tribe, and the rest are mixed cultures of Cebuano, Ilonggo and Muslims.
Four decades ago, Sta. Maria was formerly, named “KIBULAN” because of its beautiful streams & creeks. It became a Barrio by virtue of Republic Act Number 3570– The famous Barrio charter authored by Hon. Pedro Orata. History has it that the Tagacaolo aborigines originally chose to name this place “DOOL”. However,the name gradually lost in the memory of the people and was changed to Sta. Maria which was then created as a municipality by virtue of Executive Order Number 104 in 1965 by his Excellency President Diosdado Macapagal. However, Sta. Maria was reverted back to its original status as a Barrio when Executive Order Number 104 was declared through Congressman Ismael Veloso.
If there was anything among other great things that President Ferdinand E. Marcos has done to Sta. Maria, was the restoration of its status as a municipality on June 18, 1968 by his approval of Republic Act Number 4743 under which the stifling effect of creation of Sta. Maria as a town that was favorably considered. At present, the municipality is struggling to attain its ultimate vision of attaining a community that is progressive, self-sufficient, globally competitive, harnessing strengths in agriculture and industry within the context of a balanced and harmonious ecosystem. The goals could be made possible with responsible citizens & leaders of dignity & integrity. above all, with God’s controlling power, plans will come to pass.
