The study aims to produce composite boards from two bamboo species i.e., Bambusa blumeana and Dendrocalamus asper. The composites were termed as “strip-board” and “shavings-board” to indicate that such was processed from shavings and strips, respectively. The strip-board was produced from 1.2 meter poles. The poles were turned into slats and were d...

The study examines the gross morphology of giant bamboo (Dendrocalamus asper) relative to varying elevation, temperature, and relative humidity in five forest areas of Bukidnon province in the Philippines. Results revealed that variations in leaf sizes and the number of nodes and internodes among elevation ranges were not significant. However, the...

A new species and a rediscovery in the genus Saurauia (Actinidiaceae) from Zamboanga Peninsula, Mindanao island, Philippines are presented here. The new species, Saurauia abbreviata, closely resembles Saurauia lanaensis Merr. but can be differentiated by having longer petioles, uniformly setose adaxial leaf surface, longer and wider leaves, more la...

Begonia tinuyopensis is described and illustrated as a new species from Zamboanga del Norte, Philippines. This new species resembles B. mearnsii by having a decumbent stem, scattered hairs over the entire plant, terminal inflorescence bearing 2 staminate tepals and 5 pistillate tepals. However, Begonia tinuyopensis is distinct by having sparse pilo...

Assessment of arthropods diversity was conducted in the three ITP of Central Mindanao University in Bukidnon, Philippines. Three sampling plots consisting of 10 x 10m were randomly laid in each of the Gmelina arborea Juss., Tectona grandis L.f, and Acacia mangium Willd. plantations. Collection of arthropods was carried-out using the combination of...

The study was conducted to evaluate the effects of the two organic concoctions namely Indigenous Microorganism (IMO) and Oriental Herbal Nutrient (OHN), vermicast and inorganic fertilizer on the growth performance of Bakan (Litsea philippinensis Merr.) seedlings. The study was conducted at the Forest Resource Development Division (FRDD) Nursery usi...

This investigation examined the species diversity and vegetation structure of the peat swamp forest on Mindanao Island, Philippines in relation to peat thickness, hydrology and physicochemical properties of soil and water. Sampling plots were randomly established along a relatively straight transect from the eastern side of the fringing tall pole f...

The present study intends to establish the relationship between the leaf size indices of Rhizophora apiculata relative to the zonation of the mangrove ecosystem in Masapelid Island. A transect line with 20 meters width and 160 meters length was established from the sandy soils up to the seaward zone of the forest. The transect was further subdivide...

Statement of the Problem: In the Philippines, industrial tree plantations have the largest share to the country’s current total log production. G. arborea and F. moluccana (= Paraserianthes falcataria) are two commercially important plantation species in the northern and southern regions of the Philippines, respectively. But, often, the quantity an...

Leaf size indices of the tree species in the peatland of Agusan del Sur in Mindanao in Philippines was examined to deduce the variation of forest structure and observed forest zonation. Using raunkiaer and webb’s leaf size classi cation, the leaf morphometrics of seven tree species consistently found on the established sampling plots were determine...

Native tree plantations are often preferred as nurse vegetation to facilitate succession as they are assumed to have favorable habitat for native species regeneration than exotic stands. To ascertain this, we characterized the respective attributes of exotic Gmelina (Gmelina arborea Roxb., Lamiaceae) and native Bangkal (Nauclea orientalis L., Rubia...

The present study was aimed to investigate the occurrence of mycorrhiza in an inland ultramafic mountain ecosystem to determine if the extreme soil conditions associated with high concentrations of toxic heavy metals could deter their presence across various elevation gradients. Twelve (12) sampling plots distributed across the major elevation grad...

Leaf-size indices of two urban tree species namely: Pterocarpus indicus forma echinatus Willd. and Sweitenia macrophylla King growing in polluted and non-polluted areas of Cagayan de Oro City, Philippines were compared to verify if air pollution could directly affect leaf morphology. The streets with the heaviest influx of vehicles per day were con...

Ficus is one of the most important plant groups in the tropical rainforest ecosystems chiefly considered as a major food source for frugivores. Ficus is the fifth most speciose genus in the Philippines comprising 104 species. In this paper, we emphasized the trophic relationship of the Ficus spp. and frugivores including the observed association wi...

Serpentine soils also known as ultramafic soils comprise 5 percent of the total land area of the Philippines. Majority of the ultramafic soils occur at the edges of the mainland and small island groups. However, little information had been known regarding inland ultramafic forest ecosystems just like Mt. Kiamo, which form part of the northern Minda...

Mangrove ecosystems along coastal areas perform a crucial role in filtering sediments and material deposits that could otherwise directly drain into marine ecosystems. Thus, the ability of mangrove species as heavy metal hyperaccumulators is important in phytoremediation. To test whether mangrove species in Pangasihan Mangrove Forest Reserve is hea...

The Philippines is among the severely deforested countries in the tropics and in Southeast Asia. Deforestation resulted to the massive loss of species including aggravated environmental-related disasters and calamities. Recent government program aimed to reforest degraded lands had been initiated through the “National Greening Program” thus the nee...

The peat swamp forest is a newly recognized forest formation in the Philippines following its discovery to science in 2005. This paper aims to present the checklist of plant species in the peat swamp forest of Caimpugan, Agusan del Sur, where such information has been lacking. The checklist was based on the collected specimens during the rapid asse...

A study was conducted to determine the effects of vermicompost application on the growth and seedling quality of Samanea saman (Jac.) Merrill in nursery condition. The experiment was laid out following a randomized complete block design with three replications and three treatments: 1) Compost; 2) 1-kg of vermicompost incorporated into 15 cm of the...

The presence of high mountain ranges in Mindanao has made the island biologically diverse. Several areas are still waiting to be uncovered by science. Information regarding species diversity & composition across the different ecosystems and habitat types is still wanting and a need to speed-up the process so as not to be overwhelmed with the incess...
