The survey showed that a total number of 109 species of NTFPs were traded locally in the tamu (open market), comprising 35 species of wild edible plants, 32 species of medicinal plants, 8 species of orchids, 4 species of bamboos, 6 species of rattans, 8 species of fish, 8 species of wild fruit trees and 8 species of other products. This survey covered ten most common tamu and major ethnic groups in Sabah, mainly Kadazandusun, Rungus and Murut.

This study aims to examine the willingness to pay (WTP) of visitors to pay an entrance fee for conservation purposes in Serinsim Substation, Kinabalu Geopark. The Contingent Valuation Method (CVM) was put into the application as the elicitation method. A total of 161 respondents were distributed using convenience sampling; however, 11 questionnaires were not usable because respondents did not completely answer them. An open-ended eliciting method was adopted and multiple linear regression was used to analyse the contingent valuation method analysis. The result shows that a total of 113 (75.3%) respondents are willing to pay more for the admission fee if the conservation fee were to be increased, while 37 (24.7%) respondents are unwilling to pay more. In addition, age and frequency of visits are the independent variables that have the greatest impact on visitors’ willingness to make. Admission fees can be increased to generate more revenue for Serinsim Substation’s efforts to conserve resources.

Improvement in the durability of oil heat treated Acacia mangium through accelerated laboratory tests was studied. A. mangium logs of 16-year-old harvested and segregated into the bottom, middle, and top portions. These were oil-heat treated in a stainless steel tank with oil palm oil as a heating medium at temperatures 180, 200 and 220 °C for the duration of 30, 60 and 90 minutes respectively. The wood samples dried and grounded into sawdust, air-dried again before undergoing durability tests. Accelerated 12 weeks laboratory durability studies conducted on the treated A. mangium. Fungi of Pycnoporus sanguineus, Gloeophyllum trabeum and Coriolus versicolors inoculated on the woods. Untreated samples used as controls. The results showed that durability of the wood improved with an increase in temperature and duration of the treatment. The oil heat treatment process reduced the attack of G. trabeum from 5.02%, 4.41% and 4.38% in the control samples to 0.54-4.55%, 0.91-4.41% and 1.08-4.38% at the bottom, middle and top portions, respectively. The attack of C. versicolors reduced from 11.48%, 14.27% and 15.68% in the control samples to 1. 87-10.19%, 3.10-12.69 and 4.78-15.10% at the bottom, middle and top portions. However, the attacked of P. sanguineus were less effective with 31.42%, 18.24% and 10.53% in control samples to 3.71-10.18%, 5.74-14.59% and 4.37-17.08% at the bottom, middle and top portions. Heavy colonization of mycelia occurs in vessels of the untreated A. mangium wood in comparison to the oil heat treated wood observed through scanning electron microscope.

This study was conducted to identify the types of non-wood forest products from the mangrove forests that are used by people of the mangrove fringe, reviewing the contribution of non-wood forest product sales of mangrove forest on the edge of the mangrove population income sources and investigate the local use of mangrove’s non-wood forest products of socio-economic development of the mangrove fringe population. The method which was used is by distributing the questionnaires and carried out formal interviews with the respondents. The locations which were studied are Kampung Limau Limauan, Kampung Bukit Kelapa, Kampung Longgom Kecil and Kampung Indrasun Laut. The questionnaires comprises of three parts which the first, second and third parts are containing the information regarding on the demographic of the respondent, the inventory of the mangrove’s non-wood forest products which sells by the respondent and the contribution of the mangrove’s non-wood forest product to the development respondent’s socioeconomy respectively. The respondents as a whole are more than 53 people and only 13 people only involved in the recruitment of mangroves. Of the total, found only three respondents whoactually depend on the mangrove’s non-wood forest products, while 10 others were only made to take the job as a sideline of mangrove forests. The types of mangrove’s non-wood forest products stated are mangrove crab (Scylla sarrata), shell (Cerithidea obtuse), cat fish (Plotosus sp.), mullet fish (Valamugil seheli) and marine shell (Polymesuda expansa). However, only four out of six products are marketed which are marine shell, shell, and mangrove crab and cat fish while the other is for domestic purposes. Based on data collected on correlation of the relationship between the average incomes of non-wood forest product sales of mangrove forests with a total average monthly income of respondents, it shows a positive relationship with r=0.527. The value of contribution of the average income from the selling of mangrove’s non-wood forest product over the total average of monthly income is 28.7 %. The Local usage value of mangrove’s product is calculated based on the formula of Local usage value = ?Pi Qi – Ci. The value of the local use non-wood forest products from the mangrove forests which are marketed by RM 1924.40 per month while the total value of products marketed locally applied to each individual is at RM 148.03 a month. As a conclusion,mangrove forests do contribute to the development of residence’s socio-economy although the value is low.

Vascular epiphyte category as well as diversity of epiphytic was studied in Pusat Sejadi, Kawang Forest Reserve Papar Sabah. Five randomly sampling plots of 50m x 40m (0.2 ha) were presented for 1 ha of the forest for the purposed of data collection. The result showed that 3 types of phorophytes (host tree) on which the vascular epiphyte attached to: standing tree, dead standing tree and fallen tree (deadwood). The standing and dead standing tree were subdivided into 3 zones which known as basal part, trunk and canopy to analyse the species richness. A total of 137 numbers of individual species with 2 groups (Angiosperm and Pteridophyte), 7 families and 15 species were found growing epiphytically on the phorophytes. According to the Shannon -Weiner biodiversity index analysis, it showed (H') was 0.98 which the vascular epiphytes were diverse, although they were not equally abundant based on the calculated value of Evenness Index (E=0.36). The species richness also less with I Margalef = 2.8. Pteridophytes (ferns) contributed more significantly to species diversity. Vascular epiphytes were more diverse in standing and fallen tree. In standing tree, fewer species were found on the tree trunk (4 species) than in the basal (5 species) and crown or canopy (5 species). Aspleniaceae and Polypodiaceae were 2 families consisted of more species which each of it had 4 species. Four species were found presented on all types of phorophytes: Asplenium nidus, Nephrolepis spp, Arcypteris irregularis and Microsorum musifolium. Asplenium nidus was the commonest species presented in all plots with good adaptations in any conditions of the forest whether in shady, partially or fully sun.
