Abstract:
This study examines the conservation status of Rafflesia magnifica, an endangered species endemic to Maragusan, with
a focus on its population, local awareness, and conservation practices. Data were collected through structured surveys and
key informant interviews to assess the residents’ knowledge, attitudes, and practices on the conservation of R. magnifica in
Barangays Mapawa and New Panay, which serve as key monitoring sites for the species. Population monitoring revealed a
significant decline in R. magnifica. In Barangay Mapawa, the number of healthy buds dropped from 13 in 2022 to just two by
May 2024. Successful blooms also decreased from five in 2022 to four in 2023, with four buds blooming in early 2024. In
contrast, Barangay New Panay recorded no buds in 2023 and only one bloom bud in May 2024, highlighting a severe
decline. The study also assessed local awareness of R. magnifica conservation. Knowledge was low (mean score: 1.65),
while attitudes were moderate (mean score: 1.75), and practices were also low (mean score: 1.76). Despite these gaps, 93.3%
of residents were aware of the species’ existence, and most recognized its critically endangered status. However, 40%
believed habitat protection did not affect blooming. The community expressed strong support for conservation, with over
90% backing protected area legislation and showing interest in conservation training. These findings emphasize the need for
immediate education programs, community engagement, and a formal management plan to ensure the survival of R. magnifica
in Maragusan
