Biodiversity and Habitat Assessment of Mount Malindawag Naawan, Misamis Oriental, Philippines

Abstract

Abstract.Habitat fragmentation results to displacement of inhabiting floral and faunal species. The resulting geographic isolation of various species affect regeneration, genetic flows and recruitment. Hence, a study was conducted in a forested area of Mt. Malindawag in Naawan, Misamis Oriental. Sampling stations were designated at the agro-forest, mid-forest and upper-forest habitat types. Species characterizations were based on DAO 2007-01 and IUCN Red List for conservation status. Results showed highest diversity index of flora at mid-forest while lowest diversity was observed in the agro-forest area. A tree species Canarium racemosum obtained highest Species Importance Value (SIV) at 38.6%, 42% and 30.8%, respectively in the three habitat types. The highest endemicity of flora was at mid-forest with 24% per DAO 2007-01 and 26% per IUCN conservation status. Majority of faunal species were birds that were mostly resident and common and were usually observed at upper-forest habitat. The relatively low diversity and endemicity of flora and fauna species could be due to the influx of human population. Various activities undertaken were threatening the inhabiting biodiversity, and therefore, demand immediate protection and conservation measures from formulating policies to increasing awareness of various stakeholders. Future related studies were recommended to increase scientific understanding on the interrelationships of socio-economic and ecological interactions of biodiversity to the inhabiting human population.

Vegetation diversity and its interspecies association with merbau (Intsia bijuga) at three habitats of tropical rain forest in West Papua, Indonesia

“…The other is positive associations (R 2 = 6.11) with strong relationships (IO = 0.83; ID = 0.81; IJ = 0.69) which found in HBGMS (Bembab mountain forest). This finding suggests that the relationship is not always exclusive to one form, either positive or negative, which is in line with Canastares et al (2017) that reported similar results. Pratama et al (2012) explained that negative associations show no tolerance for co-living in the same area or the absence of mutually beneficial relationships.…”

Inventory of Annonaceae in Abasig-Matogdon-Mananap Natural Biotic Area, Camarines Norte, Bicol, Philippines

“…Very few studies were made after Merrill, particularly on Annonaceae. Floristic studies accross the country are available (De Guzman et al 2014;Castañares et al 2017;Malabrigo et al 2017;Lillo et al 2018;Ordas et al 2019;Suba et al 2019;Paclibar and Tadiosa 2020;Moran et al 2020;Batuyong et al 2020;Biag and Alejandro 2021;Batuyong et al 2021;Biag and Alejandro 2021;Cordero and Alejandro 2021). Results of these inventories were general listings of different plant families, their distribution, ecology and conservation status.…”
