Preserving a Dying Spring

FB_IMG_1488976199398.jpg

The Filipino Cave Divers is proud to be part of a landmark move to preserve a dying spring.

As of March 5, 2017, the blue lagoon area of Enchanted River is closed for swimming. The decision came after a series of scientific studies and multi-partite consultations with the Hinatuan LGU, local tourism stakeholders, Department of Tourism, Department of Environment and Natural Resources and its Environmental Management Bureau, a team from Department of Biology, University of San Carlos, Cebu City, Filipino Cave Divers, and Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ).

In the past, swimmers would intentionally and unintentionally break off rocks from the delicate limestone walls. The rocks descend down to the underwater cave and block the mouth of the spring. As the mouth got smaller, this decreased the optimal flow of freshwater, allowing seawater to come in and destroy the river. As more tourists visited and swam in the blue lagoon, the situation became irreparable to the point that no freshwater was coming out of the spring.

Since the closure of the blue lagoon to swimming, the spring has been restored to its original condition-bluer than blue freshwater has been coming out and forcing salty water back to sea. The unimpeded flow of the freshwater benefits the ecosystem of the river which extends out to Hinatuan bay, the traditional fishing grounds of Hinatuanons.

A new swimming area downstream has been opened just outside the blue lagoon area. This will ensure visitors will still be able to experience the spring’s clean and blue freshwater.

Hinatuan Enchanted River is the most famous tourism site in Mindanao and is gaining more fame around the country and in the world. Help us protect it for the present and future generations to come. It is the only one of its kind in the Philippines.

Biophysical Survey of the Enchanted River: A Scientific Report

Foreword by Ms. Ethel Wagas:

This article is an output from FCD’s project entitled “Rapid Resource Assessment of Four Philippine Underwater Cave Systems”, funded by The Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) under the PAME Project, in partnership with the Department of Biology of the University of San Carlos and the local government unit of Hinatuan, Surigao del Sur.

This was the very first scientific investigation on the flora, fauna and water properties of the Hinatuan Enchanted River Underwater System. The exploration was made possible through the collaboration divers, field scientists and representatives from the local government – with the aim of better understanding the ecosystem of both the underwater cave system and its connecting river. This is also the first scientific article produced by the Filipino Cave Divers published in Annals of Tropical Ecology.

The Marigondon Cave of Mactan: A scientific study made in 1993

Foreword by Dr. Danilo T. Dy:

The 1993 scientific article was USC’s first contribution to the study of underwater caves. It was a collaborative effort between a marine geologist from the Univ. of Hamburg, Germany and researchers of the Marine Biology Section, USC. The article provided initial data on the dimension of the cave, the range of temperature, salinity, pH, dissolved oxygen & the meiofauna density inside the three sections of the cave.

Freshwater cave system in Cebu yields an undescribed species of fish

The recent exploration (Dec.7-8, 2015) to Casili Underwater Cave System in Brgy. Arpili- Balamban, gave the team the opportunity to video document a previously unobserved denizen of the deeper portion of the site.  Captured on video is a  yet-to-be described fish that was spotted at a depth of 32 meters and around 600 meters away from the cave entrance. Length of the specimen is approximately 5 inches long. The team was unable to secure a live sample for study.

Alex Santos, Jaime Lapac and Bernil Gastardo composed the  team. For the successful 2-days of exploration, much appreciation and gratitude goes to the hearty support and kind cooperation of the local council and barangay tanods led by Barangay Captain, Hon. Rhodessa Paulin.

2014: A Year of Discoveries & Trial by Fire for the FCD

The Filipino Cave Divers started the year 2014 with a series of epic discoveries. Mid-year, it suffered a devastating loss of a beloved co-founder. Forging ahead through such bitter challenge, the organization maintained its core values and expanded its membership, networks and partners. The future of the country’s underwater cave explorations, protection and management is secure in the vision that FCD has set forth. The FCD is discovering more of its potential and 2015 is going to be another year of awesome discoveries indeed!

January 12, 2014– The Siargao Island was initially explored by Doc Amores, Lyndon Cubillan and Larry Williams. Located in Baragngay Tuburan were 3 promising springs that were reported (by locals) to connect Tuburan II to Tuburan I some 2 kilometers away. https://filipinocavedivers.com/2014/01/16/search-for-new-underwater-caves-siargao-island/

January 20, 2014– The Pawod Cave was surveyed by Doc Amores, Lyndon Cubillan, Andy Berame and Jaime Lapac. This survey was to determine if the area suffered any damage during the Oct. 15, 2013 earthquake which, at its epicenter in Bohol, registered 8-9 in intensity. No damage was observed in any of the areas especially in the main chamber, and main tunnel.
https://filipinocavedivers.com/2014/01/21/pawod-and-the-big-earthquake-of-2013/

January 26, 2014– The Pawod Cave was relined by Doc Amores, Andy Berame and Jaime Lapac. Several cave divers using the cave had been leaving temporary lines in the area that were confusing. These temporary lines were removed by the team and yellow permanent lines were installed.

February 23, 2014– Doc Amores and Jake Miranda went to Tagbilaran, Bohol to attend the 18th National Cave Committee meeting chaired by the Biodiversity Management Bureau. Together they presented the credentials and exploration reports of the FCD to the committee. After viewing the presentation, NCC Chair and BMB Director Mundita Sison-Lim said, “With cave diving expertise now locally available, we have a partner in FCD to finally explore the numerous freshwater and sea caves in the different parts of the country. Previously we had to rely on foreign expertise. This partnership boosts our local capability to conduct studies on cave geology and biodiversity inside the underwater caves.”
https://filipinocavedivers.com/2014/02/27/fcd-attends-the-18th-national-cave-committee-meet/

February 27, 2014– Jake Miranda added one more letter to the cave divers TGADL acronym. FCD now utilizes the mnemonic “Thank God All Divers Live Long”. L (ong) stands for Local. As his article explains, “Local knowledge of the cave includes cave geologic characteristics and composition, water flow, depths, chambers, established lines, and important data from previous expeditions. The new letter in the acronym is added to reflect the need for the cave diver to properly study the cave and prepare for his dive inside its environment. Each cave is different and presents unique challenges to the cave diver.” https://filipinocavedivers.com/2014/02/27/thank-god-all-divers-live-long/

April 2 – 3, 2014– Doc Amores, Lydon Cubillan, Jaime Lapac, Ferdinand Edralin, Jake Mirand and Larry
Williams returned to Siargao Island to explore the several sites in Siargao Island. The Del Carmen Cenote No. 1 which was considered by the team as an epic find. The water movement in the area is affected by the tidal flow. With proper tide timing, this can either be a no-current dive or a spring dive with significant flow for pull-and-glide dive propulsion exercises.

https://filipinocavedivers.com/2014/04/18/kantoloi-twin-cenotes-of-pilar-siargao-island/

April 5, 2014– The Siargao Exploration team proceeded to explore the other sites in Del Carmen, Siargao Island. The crown jewel of the expedition was the discovery of the “Inner Sanctum”. Bamboo ladders and skills in rappelling were required to access the water’s edge. https://filipinocavedivers.com/2014/04/09/the-inner-sanctum-of-del-carmen/

May 17, 2014– Doc Amores signed-off 3 new FCD members that he started training a few months back.
Considered certified as FCD Cave Divers are Dean Apistar, Ferdinand Edralin and Marc Berame.

June 17, 2014– A very bleak point in the history of FCD was when Doc Amores passed away while exploring the Hinatuan Enchanted River. An undiagnosed heart condition was the cause of his death. He was recovered by Jake Miranda inside the main chamber, 40 meters deep with his right hand intentionally wrapped in the cave line. It was assumed that he did it so that he wouldn’t drift deeper into the cave. Doc’s last decision made the recovery safer for the team.
https://filipinocavedivers.com/2014/07/08/doc-amores-an-explorer/

June 25, 2014– In the shadow of Doc Amores’ passing and during his wake, the FCD held its first election of officers. Elected as President and Vice- President is Bernil H. Gastardo and Andy Berame respectively. The Board of Directors and the new officers vowed to continue Doc’s advocacy to protect and preserve the country’s underwater caves and marine resources.

July 2, 2014– 7 Concept Note proposals for the exploration and consequent protection of 2 sites in
Cebu and 5 sites in CARAGA region were sent to the main office of the DENR-GIZ Protected Area Management Enhancement (PAME) Project. These proposals were initially worked on by Doc Amores.

August 11, 2014– The Final Proposals for the survey and protection of cave sites in Cebu and CARAGA region were hand-carried to the PAME HQ in Quezon City by Joseph Nacario to meet the deadline. This was after a rigorous 4 days & 3 nights writing binge by the FCD proposal writing team composed of Jake Miranda, Joseph Nacario and Dean Apistar.

September 8, 2014– Executive Order 2014-24 which is “An Order Organizing Task Force Pawod” was enforced by the Lapu-Lapu City Hall. The committee is composed of 12 members– the City’s elected officials, executives and 1 private organization (FCD). The initial meetings opened a lot of possibilities for the development and protection of the Pawod Underwater Cave System. A management workshop will be conducted on January 2015.
https://filipinocavedivers.com/2014/07/26/docboys-cave-aka-the-pawod-underwater-cave-system/

September 26, 2014– The FCD held its 1st Convention in Mactan. Members joined in the survey of Pawod and an Advanced Buoyancy, Trim and Propulsion Workshop was conducted by UTD Instructor, Juan Naval. https://filipinocavedivers.com/2014/10/17/the-1st-fcd-convention/

October 14, 2014– Alex Santos conducted an IANTD Cave Diver training in the exotic and beautiful Paglugaban Cave in El Nido, Palawan.
https://filipinocavedivers.com/2014/11/09/the-paglugaban-cave-of-el-nido-palawan/

November 28, 2014– The FCD signed a Memorandum of Understanding with the University of San Carlos- Biology Department for the exploration and study of the underwater caves in the country. https://filipinocavedivers.com/2014/11/29/fcd-and-usc-a-partnership-for-the-underwater-caves-of-the-philippines/

Dec. 1, 2014– A contract was awarded to FCD by GIZ to survey 4 underwater cave systems until May 2015. The sites to be surveyed starting January 2015 are Casili (January), Silop (February), Hinatuan (March), and Bababu (April).

The Silop Cave Complex

Silop Cave Complex (SCC) is in Barangay Silop, Surigao City, Surigao del Norte, Caraga, Philippines, which silop2is accessible via daily flights from Manila and Cebu.  SCC is located at 9.740553°N, 125.515011°E. It is just 15 minutes from the Surigao City Airport.  It now has sixteen-cave entrances system (out of a possible 23) as of June 2014.

Of particular interest is Cave 4a which is part of the established 16 other entrances. It is the only water cave in the system where freshwater runs through the cave at an average depth of 5 feet in the dry season. Certain lengths are as deep as 8 feet. Source pool is 20 feet deep or deeper. The cave is estimated to be 1,000 meters long to reach the source pool.

As of today, there is no baseline information for which the LGU can use as basis to start protecting the area. Today cave 4A’s waters remain an enigma as to its contents, composition and importance to the surrounding forest. Since 2011, the FCD members have spent personal finances to investigate the nature of the SUCS to find out about the value of protecting the area against urbanization. silop_image

Fish, shrimp and bats are commonly found. However, it is under threat from siltation and runoff caused by gold-panning activities in nearby upland areas. In the surrounding areas, unclassified bats and primates are commonly seen.

The Silop Underwater Cave System (SUCS) is a contiguous ecosystem joining the underwater cave and the terrestrial area that are unique and a home to a wealth of unexplored biodiversity. Concerned stakeholders now fear that the gaining popularity of the site will result in the degradation of the critically fragile ecosystem and will result to the loss of the still undocumented biodiversity treasure.

The main threats that can be reduced are the siltation and brown water effect that unfortunately are diffusing to nearby Barangay Silop. The other major threat that this project wants to address is the lack of site-specific policy and mechanisms to safeguard this fragile ecosystem. There is also lack of framework in which development and utilization of the area can follow on

The Local Government Unit is amenable to the conservation of the area due to its enormous potential for eco-tourism and understands that intervention must be brought-in in order to preserve the area’s main attraction-its pristine and water feature. It can be said that currently, there are no significant interventions for conservation being done in the area.

The key stakeholders of the SCC and terrestrial ecosystem include the people and communities of Surigao City, the barangay of Silop and of the Province of Surigao del Norte, along with the tourists and the tourism service sector.

This is one of the areas that the FCD will be surveying early next year with the funds received from the BMB- GIZ PAME project.

A Journey of Discovery

what lies bemeath..The Filipino Cave Divers (FCD) has been contracted to take the lead in an exciting and pioneering project called the “Assessment of Terrestrial and Aquatic Biological Diversity in Selected Aquatic Cave Systems”!

This ground- breaking endeavor which will be undertaken with FCD’s scientific partner, the University of San Carlos- Biology Department,  is under the close supervision of the Department of Environment and Natural Resources (DENR) which has partnered with the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB). The implementation of the cave assessments falls under the Protected Area Management Enhancement (PAME) Project.

PAME projects are jointly implemented by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and DENR’s Biodiversity Management Bureau (BMB).

A rapid source assessment of 4 underwater cave systems will be made in Cebu (1) and CARAGA (3):

  1. Casili Underwater Caves System – Balamban, Cebu
  2. Silop Cave Complex- Surigao City, Surigao del Norte
  3. Enchanted River Underwater Cave System- Hinatuan, Surigao del Sur
  4. Bababu Lake Underwater Cave System- Basilisa, Dinagat Islands

The main tasks and activities that are expected from the FCD and from the University of San Carlos- Biology Department are as follows:

  1. Generate biological profile of the underwater caves including invertebrates;
  2. Produce vegetation profile outside the cave;
  3. Mapping of the underwater cave (inside and outside);
  4. Generate hydrological profile to include water quality (temperature, pH, nutrients, coliforms, salinity and biological oxygen demand), water current directions and velocity and water level rise;
  5. Develop management options per cave as basis in management planning;
  6. Develop assessment and monitoring protocols for the underwater caves.

The project contract was signed last December 4, 2014 and project activities will be undertaken until May 31, 2015.

Please stay tuned for updates as the Filipino Cave Divers and the USC- Biology Department embark on a journey of discovery that will show to the country and to the rest of the world the beauty, complexity and the biodiversity that reside in the underwater world of freshwater and anchialine caves in the Philippines!
