Great and Little Sta. Cruz Islands Protected Landscape/Seascape and Regional Geography

The protected area is best known for its dual designation as both a protected landscape and a protected seascape, bringing together small offshore islands and their surrounding marine waters into a single conservation unit. It represents an early example of integrated land-and-sea protection in the southern Philippines. The Sta. Cruz Islands are also recognized as one of the notable natural tourism anchor points of the Zamboanga region. Local and national authorities have formally supported the development of the islands as a destination for high-quality ecotourism, making the area notable for the way conservation planning and tourism strategy have been linked from an early stage.

The Great and Little Sta. Cruz Islands Protected Landscape/Seascape was formally established on 23 April 2000 through Presidential Proclamation No. 271. The proclamation created a combined protected landscape and seascape around Great Santa Cruz Island and Little Santa Cruz Island, setting the foundation for integrated management of the islands and their surrounding waters.

In 2011, the Philippine Department of Tourism and the Tourism Infrastructure and Enterprise Zone Authority, working with the city government of Zamboanga City, signaled their support for developing the Sta. Cruz Islands into a premium ecotourism destination. An architectural study was commissioned to guide the design of any future developments and to ensure consistency with environmental and aesthetic goals. A budget of 20 million Philippine pesos was allocated for this initiative.

The area continues to be managed under the National Integrated Protected Area System, the overarching Philippine framework for protected-area governance, linking the islands to the country's broader biodiversity and conservation planning efforts.

The landscape setting of the protected area is defined by its position just offshore from the southern tip of the Zamboanga Peninsula. The Zamboanga Peninsula is a long, narrow arm of Mindanao reaching southwestward, and the Sta. Cruz Islands sit in the coastal waters near where this peninsula approaches the Sulu Sea.

Great Santa Cruz Island and Little Santa Cruz Island together with their surrounding waters make up the core of the protected landscape and seascape. The dual designation reflects the inseparability of the islands and the sea around them, with sandy shores, intertidal zones, and nearshore waters forming a continuous coastal mosaic. A buffer zone extends the protected area outward into the surrounding marine environment.

As a combined landscape and seascape protected area, the Sta. Cruz Islands Protected Landscape/Seascape is designed to conserve both island habitats and the adjoining marine environment. The protected status links the ecological condition of the islands to the health of the coastal and nearshore waters, recognizing that the two systems are functionally interdependent.

The area forms part of the broader suite of protected natural assets of the Zamboanga Peninsula region, an area recognized for its mix of coastal, marine, and terrestrial habitats in the southern Philippines.

The protected area is one of several formally designated conservation zones on the Zamboanga Peninsula, standing alongside other protected landscapes, natural biotic areas, and resource reserves across the region. Its combined landscape-and-seascape designation provides a legal and management framework for protecting both the islands and the productivity of the surrounding marine environment, including through the use of a marine buffer zone.

By placing land and sea under a single proclamation-driven management regime, the area serves as a model of integrated coastal conservation in the southern Philippines, helping to preserve ecological connectivity and reduce fragmentation between terrestrial and marine management efforts.

The defining feature of the Sta. Cruz Islands Protected Landscape/Seascape is its combined protected landscape and protected seascape status, one of the simpler yet more instructive examples of integrated conservation governance on the Zamboanga Peninsula. The protected area's recognition as a regional tourism anchor, supported by formal ecotourism planning linked to conservation, makes it a useful case study in sustainable destination development.

The buffer-zone arrangement, which adds marine space around the core island territory, also highlights how the Philippine protected-area framework accommodates coastal and marine values alongside traditional terrestrial protections.

The protected area's coastal and island setting gives it a tropical maritime climate shaped by the broader weather patterns of the southern Philippines. Sea conditions around the Sta. Cruz Islands tend to be calmer during typical dry-season months, which is also when accessibility by ferry from Zamboanga City is generally more favorable. Visitors interested in coastal scenery, island landscapes, and the marine environment can expect a tropical island atmosphere year-round, with seasonal patterns influencing sea state more than temperature.
