Beautiful photos of flowering trees at the foot slope of the Mount Kanla-on Natural Park in Negros Island have spread online during the past weeks. Specifically found in Sitio Calapnagan, Brgy. Biak-na-Bato, La Castellana in Negros Occidental, about two to three hours drive from Bacolod City, the blooming trees, with the imposing background of the Kanla-on Volcano, were photographed by several persons and they uploaded some photos in social media. The views are, indeed, marvelous as they really look like the Cherry blossoms, or Sakura trees, which are popular attractions in Japan. From then on, according to MKNP staff, the number of visitors increased at Calapnagan, where the administration center of the park is also located.
Alleged Palawan cherry blossoms
One article posted at www.choosephilippines.com claimed that residents in the area called these trees Palawan cherry blossoms. It caught my curiosity, because I was suspecting that the trees, with a mixture of pink, red, white, and yellow colored flowers, are not the Palawan cherry blossoms (Cassia javanica ssp. nodosa) that are recently known to me. The photo accompanying the said online article reminded me of similar pictures I took at the site almost two decades ago.
I requested one of the MKNP staff, Errol Gillang, to take close-up photos of the flowers, trunk, and leaves of the tree so I could consult some of my friends, who are botanists or with interests and working on botanical concerns, as to the exact identification of the species. After receiving several photos from my namesake, I shared them online, particularly Facebook, and responses to my post are interesting. Some friends pointed out the tree is similar to Palawan cherry, but a few suspected it as Salingbobog, known to science as Craveta religiosa, and one of our native species that can be found as well at the Diliman campus of the University of the Philippines. Surprisingly, Gillang told me they found a plate in one of the trees that states it is Akle (Albizia acle), a species native in the country.
Antsoan and Pink shower trees
It was botanists Pat Malabrigo and Pieter Pelser of the UP Los Baños and University of Canterbury, respectively, who confirmed that the species is Cassia javanica ssp. javanica or Antsoan, which is a non-native species of the Philippines, or an exotic one. Malabrigo further asserted that the so-called Palawan cherry, known as Pink cassia or Java cassia, is not native to the Philippines although it bears Palawan as its popular name, simply because it is widespread in that province.
Gillang sent me additional set of photos of lovely pink-colored flowers of another tree he found in Sitio Pabrica, Brgy. Cabagna-an, La Castellana and within the MKNP, too. I similarly posted the photos on my Facebook account, and Pelser identified it as Cassia grandis, a species native to tropical America. The common English name of this tree is Pink shower, according to biologist Renee Paalan of the Silliman University.
My Facebook posts on the two flowering plants received numerous and varied reactions. Many of my friends were amused of the beautiful color and gorgeous look of flowers, and some requested information where to secure the seeds or seedlings of trees, while many expressed interest to visit the sites where the two species are found. On the other hand, several friends in the conservation community were alarmed to know the presence of these exotic species in the protected area, and they urged the planting of indigenous or native trees, while suggesting the eradication of non-native species, because they might affect the biodiversity of the MKNP.
Forester Edgardo Cueto, a Ph. D on forest resources management recommended for the conduct of risk analysis to determine the impacts of exotic species on the MKNP’s biodiversity. He said the introduction of exotic species might “entail the modification of entire ecosystems, including overgrowing and shading out native species, changing fire regimes, and modifying water and nutrient systems.” Cueto added the species hybridization and introgression and ultimately the invasive meltdown are possible consequences. The result of the assessment shall be used in the decision-making by either extirpate the species or let them be managed properly, Cueto said.
Other exotic species and reforestation
The Antsoan is not the only exotic plant found at the MKNP administration center, as there are also mahogany, gmelina, eucalyptus, and a particular species of teak (Tectona grandis), among others, although several native species are available at the site, too. These trees were planted in the 1960s to 80s as part of the reforestation project of the then Bureau of Forest Development, and later on the Department of Environment and Natural Resources, forester Johnny Flores, who served as a manager of the project site at one point in time, said.
I could only assume that the planting of these exotic species in the area was done with noble intention of reforesting the site that was badly deforested prior to it, according to local folks. I think, the issue of exotic species in relation to biological diversity has never been considered seriously at that time. If my recollection is right, it was only in the mid 80s when the issue of biodiversity started to become popular and the advocacy for planting of native plant species emerged.
I could recall that the late forester Larry Cayayan, who was then the Provincial Environment and Natural Resources Officer of Negros Occidental in early 1990s, once told me the reforestation at Calapnagan included the planting of flowering trees at the park’s boundary so there would be visible markers that will separate it from private lands. He opined that in a way these flowering trees would be an added attraction of the park.
Most likely, with the influenced of the government’s reforestation project, settlers, not only at Calapnagan but also in other barangays within Mount Kanla-on, planted trees, comprised mostly of exotic species, in their backyards and farm lots, while others established tree farms. While Mount Kanla-on was established as a national park in 1934, it has never been spared from settlements that became political units as barangays through the years.
Mount Kanla-on and NIPAS
Mount Kanla-on became an initial component of the National Integrated Protected Areas System with the enactment of Republic 7586 in 1992. The NIPAS Act transformed the national parks and other nature reserves to protected areas, and from then on, biodiversity conservation was the focused on the establishment and management of these sites. Prior to this, we were largely following the American-tailored national park system, as introduced by the American colonial regime in 1932. As one measure to protect the biodiversity, the DENR came out with a guideline prohibiting the introduction of exotic species in protected areas.
When I was the park superintendent of the MKNP, from 1995 to 2002, my staff and me were aware of the presence of these exotic species. We knew these flowering trees, but with all honesty, we were unsure at that time if this so called Palawan cherry is an exotic species, although we were more in suspicion that it is, indeed, a non-native tree. I did not take much interest over these trees, because some are planted in the disputed “private lands” within the MKNP. I reviewed the 1st management plan of the MKNP, but unfortunately it did not list and discuss exotic species.
Considerations and possible options
The Protected Area Management Board of the MKNP, when I was still the park superintendent, came out with a policy allowing the cutting of planted and exotic species in the area. The purpose of the guideline was to minimize pressure to remaining natural forests by allowing communities to utilize and benefit from their planted exotic trees. In every tree cut, a replacement of five native species was required. It was also a way to eradicate exotic species in the area. The policy did not include cutting of trees at the government’s reforestation sites, as there might be issues on audit regulations.
I was at the MKNP administration center last year, and I observed that it seems the number of these exotic trees did not increase. I noticed some mahogany trees are already invaded with vines and other plants, while several undergrowth species are noticeable. The interest of the local government of La Castellana to promote this area for tourism purposes is understandable and a good idea. In fact, in the original management plan of the MKNP, this site has been identified as ecotourism zone, because, aside from the remaining natural forests found in the area, it is here where one can have a good view of the towering Kanla-on Volcano, and it is ideal for picnic, camping, and other outdoor activities.
I am amendable to Cueto’s recommendation to conduct a study on exotic species and its impacts, not only at Calapnagan, but the entire MKNP so that appropriate conservation measures shall be adopted by the PAMB. MKNP is also gifted with numerous native flowering plants that can be propagated. The MKNP Act of 2001, or Republic Act 9154, prohibits the establishment and introduction of exotic species with allelopathic effect, or those detrimental to endemic species, or without prior PAMB permit.*

The Protected Area Management Board, the site-based policy and administrative body of the Northern Negros Natural Park, should heed the recommendation of its Technical Working Group to order the demolition of illegal structures in the protected area, especially those that were constructed by private individuals, who have no right to stay in this biodiversity-important site.
The recommendation of the TWG came after it was tasked by the PAMB to assess and evaluate the different structures in the NNNP and to come out with possible courses of action.
It can be recalled that the Provincial Environment and Natural Resources Office has issued at least 89 cease-and-desist orders to private individuals, who have been found to have constructed vacation houses in the NNNP without prior permit from the PAMB. Since NNNP is a component of the National Integrated Protected Areas System of the Philippines, as provided for in Republic Act 7586, it is a requirement that the construction or maintenance of any kind of structure, fence or enclosures, and conducting business enterprise, require the issuance of appropriate permit from the PAMB.
The PAMB is not in the position to make any decision that are contrary to the NIPAS. The regional executive director of the Department of Environment and Natural Resources in Region VI, who acts as the chair of the management board, should make sure that the PAMB acts within its power and authority, and in conformity with appropriate laws, rules and regulations. The DENR Secretary has the power to overturn decisions rendered by the PAMB that are not appropriate in the management of protected areas, like the NNNP.
While it is true that NNNP is a protected area, it is not absolute that occupancy is not allowed. However, it is only allowed in the designated multiple use zone and restricted only to the so-called tenured migrants. Based on the revised implementing rules and regulations of the NIPAS Act, the household head shall be considered a tenured migrant if proven to have actually and continuously occupied a portion of the protected area five years before its designation under the NIPAS, and solely dependent therein for subsistence.
Tenured migrants should be organized to avail a land tenure privilege, known as the Protected Area Community Based Resource Agreement, which shall be awarded by the DENR upon the endorsement of the PAMB. The purpose of this arrangement is to control occupancy and create strong social fence. It is the responsibility of the beneficiaries of land tenure to ensure that no additional migrants will stay in the awarded sites.
Based on the initial evaluation by the DENR, the recipients of the CDOs are not actually tenured migrants, since all of them are residents of areas outside the NNNP and they are not subsistence persons.
Aside from violating the NIPAS once the PAMB allows the owners of these vacation houses to occupy portions of the NNNP, it shall become a precedent and others may also follow. If that is the scenario, the PAMB will be out of control and becomes an ineffective management body of the NNNP.

The recent Asian Waterbird Census in Negros Occidental jointly conducted by the Philippines Biodiversity Conservation Foundation, Inc., Negros Forest and Ecological Foundation, Inc., Department of Environment and Natural Resources and Provincial Environment and Management Office affirmed the province’s importance in terms of biodiversity conservation in global scale. The findings of the survey may also boost the potential of Negros Occidental as an important birding site in the Philippines.
Lisa Paguntalan, PBCFI Director for Field Operations and one of the members of the survey team disclosed that migratory bird species are abundant in wetlands and coastline areas of Pulupandan, San Enrique, Pontevedra and Ilog municipalities and Kabankalan City. The variety and number of species found in these areas are good enough to propose their declaration as Wetlands of International Importance under the Ramsar Convention.
In Pulupandan, the survey team recorded a total of 38 waterbird species comprising of 2,851 individuals. This site accounts the highest number and population of duck species among the areas covered by the survey. Among the species recorded in this site were Black-winged stilts, Egrets and Whistling duck. The endemic Philippine duck has been noted also in Pulupandan wetlands. In San Enrique-Pontevedra wetlands, some 37 waterbird species involving 10,939 individuals were counted by the survey team. Thirty two species in these sites are migratory birds. Species identified in San Enrique-Pontevedra wetlands included Asiatic dowitcher, Chinese egret, Eurasian curlew, Far eastern curlew and Black-tailed godwits.
On the other hand, the survey in Kabankalan-Ilog wetlands recorded a total of 50 waterbird species of which 34 are migratory birds. The individual species count in these wetlands reached about 13,764. Some species identified in these sites are similar with the species discovered by the survey team in San Enrique-Pontevedra wetlands.
Paguntalan, an ornithologist by profession, said the recent waterbird census in Negros Occidental yielded some interesting scientific notes and facts. She claimed the survey recorded the Little stint (Calidris minuta), which was only recorded in the country in 1903 and it was the first record of the species in Negros since 1888. The survey also resulted to the 4th record of Caspian tern in the Philippines and so far the highest number of individuals recorded. The 4th record in the Philippines and second record in Negros of Sanderling (Calidris alba) were similarly obtained during the waterbird census. The 3rd country record of the Broad-billed sandpiper (Limicola falcinellus) was further made during the survey.
The surveyed areas are actually considered migration or navigational routes of the migratory birds or also known as Migratory Flyways. In the Philippines, only the Olango Island in Cebu has been recognized as part of the East Asian – Australian Flyway. These migratory sites are very important to several species of birds that are taking refuge in tropical countries during winter. Usually migratory birds attract the interest of global birding community.
So far, there are only four sites in the Philippines declared as Wetlands of International Importance and these are the Olango Island in Cebu, Naujan Lake in Oriental Mindoro, Tubbataha Reef in Palawan and Agusan Marsh in Agusan del Sur. The Convention on Wetlands of International Importance or popularly known as Ramsar Convention is an inter-governmental treaty providing the framework for national action and international cooperation for the conservation of wetlands and their resources. It is the only global environmental treaty focusing on a particular ecosystem and was adopted in 1971. The Philippines is one of signatories of the treaty.
