    Economic valuation of ecotourism resources as a conservation tool for the Makiling Botanic Gardens

    The Makiling Botanic Gardens (MBG) is one of the ecotourism points of interest in the Mount Makiling Forest Reserve ASEAN Heritage Park (MMFR AHP) and the nearest mountain ecosystem to Metropolitan Manila, Philippines. The MBG serves as a living collection and sanctuary of endemic and endangered plant species in the Philippines and promotes public awareness and appreciation of biodiversity through conservation education. The MMFR’s recognition as AHP in 2013 has received support and assistance from different agencies to further develop its ecotourism potential. However, developments are anticipated to be at the expense of low-priced ecotourism services. The study aimed to estimate the willingness to pay of MBG visitors for its enhanced conservation using the contingent valuation method. The contingent valuation survey was administered through face-to face interviews. Results show that out of 253 respondents, 79% expressed willingness to pay (WTP) for the enhanced conservation of MBG. The elicited mean WTP is PhP 73.79 ($1.46) on top of the current entrance fee of PhP 50.00 ($1)/visit. The significant factors affecting visitors’ WTP were bid amount, income, and education. Given the elicited mean WTP added to the current entrance fee and the average number of visitors of MBG (41,281) annually, the potential revenue of MBG if the WTP will be captured is about PhP 6.3 million ($124,758). Results of the study can serve as a reference in adjusting the entrance fee of the MBG to support the full implementation of MMFR's management plan in the context of an ASEAN Heritage Park.

    Tourists’ willingness-to-pay for groundwater conservation, Mt Makiling, Philippines
    XV World Forestry Congress, 2-6 May 2022

    Mt Makiling is a dormant volcano that supplies hot water to springs and groundwater in Los Baños and Calamba City, Philippines, spurring the development of a resort-based tourism industry that is heavily extracting groundwater. The paper discusses the results of a contingent valuation survey that sought to evaluate the tourists’ knowledge about the resorts’ water source and use practices, reasons for visiting, willingness-to-pay for improved water conservation practices and the conservation of Mt Makiling as water source, and whether they would visit the resorts during the COVID-19 pandemic. About 50% of 492 respondents were aware of the resorts’ water source, with about half saying that the source is hot springs, but only a few were aware of groundwater as the water source. The main reasons for visiting the resorts are for relaxation and the resorts’ accessibility and affordability. The estimated mean WTP ranged from PhP75/visit (payment card) to PhP174/visit (dichotomous choice), and the respondents were willing to pay because they would like to contribute to the conservation of the groundwater resource of Mt Makiling and because groundwater is limited. On the other hand, some respondents were not willing to pay because they could not afford the additional amount and they perceive that they should not be made to pay for the cost of proper recycling of pool water. Most of the respondents said they would still consider visiting resorts during the pandemic to enjoy the pools and the environment and for the health benefits from the hot-water pools. A higher preference for private resorts was observed because these can be used exclusively by a group. The respondents who do not want to visit resorts during the pandemic said they would consider visits again if compliance with health and safety protocols would be assured. Finally, majority of the respondents recognize that the new health and safety standards for resorts will result in higher fees charged by resorts.

    Variability in the early growth of Parkia timoriana (DC.) Merr. from Mount Makiling Forest Reserve, Luzon, Philippines and its applications in conservation and forest restoration

    This study evaluated the early growth performance of selected mother trees of Parkia timoriana (Fabaceae) and characterized the suitable environmental (soil and light) factors for the growth of the species. P. timoriana seedlings from different mother trees from the Mount Makiling Forest Reserve (MMFR), Luzon, Philippines were grown in two soil media under greenhouse condition and field trial planted in the University of the Philippines Laguna-Quezon Land Grant (LQLG), where P. timoriana is not occurring naturally and soil and climate differ significantly with the MMFR. Early growth performances in height and ground basal diameter (GBD) or root collar diameter (RCD) both in the greenhouse and field trial plot were measured. Nursery-based performance showed that the average RCD was generally higher in MMFR than LQLG soil but the overall difference was not statistically significant. In contrast, overall average height was consistently higher in LQLG than in MMFR soil, but similar to RCD the difference was not statistically significant. Under different light conditions in the field trial, there was significant difference in mortality, tree height, and GBD. The differences in both the height and GBD may be attributed to the genotype of the mother trees, but height can additionally be attributed to the interaction of the genotype and the different light conditions. Results suggest that P. timoriana can be grown in areas of different soil condition, but it requires partial shade in order to achieve its full growth potential during the early stage of its growth. Hence, P. timoriana when used in reforestation or tree planting projects must consider differences in the early growth response of seedlings according to its genotype as well as light conditions. However, it is highly suggested that growth performances among provenances of P. timoriana and other environmental variables that may affect growth of the species should be looked into.
