Abstract. Solfiyeni, Mukhtar E, Syamsuardi, Chairul. 2022. Distribution of invasive alien plant species, Bellucia pentamera, in forest conservation of oil palm plantation, West Sumatra, Indonesia. Biodiversitas 23: 3667-3674. Bellucia pentamera has been found in disturbed forests across Indonesia, but little is known about how it spreads under its tree canopy. The spread of the invasive plant B. pentamera in the PT KSI conservation forest area was investigated. The goal of this research is to study B. pentamera's strategy for exploiting forest gaps horizontally and vertically on degraded forest vegetation invaded by B. pentamera at various degrees of invasion. An Unmanned Aerial Vehicle (UAV) and direct field mapping are used for the mapping approach. Aerial photographs revealed 40 B. pentamera trees and 32 non-B. pentamera trees in forest areas with varying degrees of B. pentamera invasion (based on the ratio of B. pentamera non-B. pentamera: dense and loose). Bellucia pentamera trees were distributed evenly in a large gap and randomly in a small gap/space between the canopy, whereas sapling and seedling B. pentamera trees were distributed in groups, uniformly and randomly, according to microhabitat conditions under the canopy of B. pentamera and non-tree trees. Bellucia pentamera seedlings and saplings were detected under the parent tree's canopy rather than in the canopy gaps. Different responses were seen in seedlings, saplings, and juvenile stages concerning the explanatory factors investigated and between the two stands. The purpose of the study was to determine the factors that influence the distribution of the B. pentamera species in conservation forest areas with different compositions of existence, both vertically and horizontally, using drones and direct measurements in the field.

“…Evolvulus nummularius (L.) L., commonly known as "roundleaf bindweed," is a species under the Convolvulaceae (morning glory) family that grows in tropical and subtropical regions around the world (Iqbal et al 2020). The species is considered native to Mexico, Central America, and other South American countries (Stearn 1972;Iqbal et al 2020). In the Philippines, there is only one species previously reported under this genus -the Evolvulus alsinoides (L.) L., which has a bushy herbaceous habit and sky-blue colored flowers (Burkill 1985).…”

“…It is considered to be widespread throughout the country (Pelser et al 2011 onwards) but can be found growing in tropical and subtropical regions around the world (Kuppusamy et al 2021). On the other hand, the alien E. nummularius species has been reported outside its native range such as in Africa, China, India, Bhutan, Pakistan, and neighboring countries like Malaysia, Myanmar, Bangladesh, and Taiwan (Sultana and Rahman 2016;Iqbal et al 2020) but never in the Philippines. This paper is the first report on the occurrence of the said species in the Philippines, particularly in Davao City, Mindanao.…”

“…To verify the correct identification of the species, all the information regarding its taxonomic descriptions was obtained from the study of Stearn (1972), Sultana and Rahman (2016), and Iqbal et al (2020. Based on its protolog, Linnaeus named the species Convolvulus nummularius in the Species Plantarum: i 57 (1753), with information as follows: Type locality: Jamaica.…”

Evolvulus nummularius (L.) L. of the Convolvulaceae family has a pantropical distribution, but its occurrence is reported first time in the Philippines. The discovery of this alien species began during the photo documentation of the plant specimens in the botanical garden at the College of Science and Mathematics, University of the Philippines Mindanao campus. It was found growing on clayey soil and thought to be naturally growing in the botanical garden. However, we found out that it was intentionally planted as a cover crop to avoid soil erosion and to reduce mud formation on the pathway to the garden during rainy days. The species is believed to be introduced in the country by traders or enthusiasts as an ornamental or medicinal plant. Though its cultivation is contained within the botanical garden, the species is considered invasive in many countries. Therefore, its cultivation needs to be regulated, and proper management must be put in place in the botanical garden in order to prevent its possible colonization in surrounding areas and across the country.
