Diversity of moths in forest plantations and natural forests in Sabah

AbstractThe diversity of macromoths in the various fast-growing exotic tree plantations and natural secondary forest in Brumas, Sabah, Malaysia was assessed by means of an annual cycle of light-trap samples. The moth diversity in the forest plantations, viz. Acacia mangium, Gmelina arborea, Paraserianthes (=Albizia) falcataria, Pinus caribaea, and in particular Eucalyptus deglupta, was unexpectedly high. Eucalyptus deglupta showed moth diversity as high as that in the natural secondary forest, a finding attributed to the fact that the E. deglupta plantation had a very diverse understorey both in terms of plant species (secondary regrowth species) and architecture, and thus supported a more diverse moth fauna. Subsidiary samples showed that primary natural forest in the neighbouring Danum Valley does not show higher moth diversity compared to the disturbed forest habitats in Brumas, though moth diversity at Danum is lower than that recorded in other Bornean primary forests. The value of plantation forests for conservation of invertebrate diversity is discussed, together with the implications for plantation management strategy.

AbstractCanopy knockdown of arthropods using mist-blowing was carried out in Brumas, Sabah (north-east Borneo), in plantations of exotic (non-indigenous) tree species (Acacia mangium, Eucalyptus deglupta, Gmelina arborea, Paraserianthes [=Albizia] falcataria, and Pinus caribaea), plus secondary natural forest and dense understorey within E. deglupta stands. Each habitat had three 1 m2 samples taken four times in one year. The average arthropod species richness within the stands of the exotic tree species ranged from 27 in E. deglupta, to 68 in natural, secondary forest. The total number of individuals caught ranged from 137 in G. arborea to 1628 in secondary forest. The dense and plant-species rich understorey within E. deglupta stands yielded both higher numbers of species and individuals than the eucalypt trees themselves, indicating the importance of allowing the development of a luxuriant understorey for the enhancement of conservation and biodiversity. Though arthropod biodiversity is reduced by the conversion of tropical forests to plantations, abundance and richness are still substantial in the latter habitats.

This study was aimed to identify the dominant species establishing during regeneration, their species diversity and whether selection thinning could enhance the regeneration of secondary forest species. Chittagong University Forest was selected for the study and harvested and unharvested sites of forest plantations were demarcated and set 30 quadratic plots (3m × 3m) for each site. Ten per cent selection thinning was done in harvested site although a little anthropogenic disturbance was noticed in both the plantations. Regenerations were identified into species level and their numbers were counted. Shannon-Weiner diversity index for unharvested plantation was 2.21 and it was 1.45 for harvested plantation. Species evenness index was recorded as 0.81 and 0.74 for unharvested and harvested plantations respectively. Both the plantations did not show a significant difference in diversity of species. According to the Important Value Index (IVI) the dominant species in the harvested site were Acacia auriculiformis followed by Acacia mangium and Albizia lebbeck. In the unharvested site, IVI was the highest for Acacia auriculiformis followed by Aphanamixis polystachya and Lagerstroemia speciosa. In both the sites, Acacia auriculiformis had a significantly (p<0.05) higher number of regeneration in harvested plantations than those of unharvested plantations. Therefore, thinning has a positive impact on natural regeneration and Acacia auriculiformis is the best for natural regeneration in plantations.

Primary natural forests generally have higher biodiversity and biomass compared to secondary forests. This study aimed to analyze the species composition, forest structure, biomass and carbon stock in the Old Secondary Forest (HST), Young Secondary Forest (HSM), and Old Shrub Forest (HBT) in Peatland Protection Area, Musi Banyuasin Regency, South Sumatera Province. Forest inventory was conducted in measurement plots of 100 m x 100 m in the HST, HSM, and HBT. The results recorded 39 species of 20 families and 565 standing trees with a diameter of ≥ 10 in the HST, 48 species of 20 families and 430 standing trees in the HSM, and 2 species of 1 family and 4 standing trees in the HBT. Vegetation at the tree level in the HST was dominated by Eugenia sp., Alseodaphne insignis, and Adenanthera pavonina, while the HSM was dominated by Macaranga maingayi, Koompassia malaccensis, and Alseodaphne insignis, and the HBT was dominated by Acacia mangium and Acacia crassicarpa. The biomass and carbon stock of standing trees in the HST were 181,61 t/ha and 90,79 t C/ha, respectively; in the HSM were 117,04 t/ha and 58,51 t C/ha; while in the HBT were 1,33 t/ha and 0,66 t C/ha. The results revealed that carbon stock in the HST was higher than that in the HSM and HST.Keywords: carbon stocks, carbon uptake, Musi Banyuasin, peatlands, vegetation structure

In the period between 2003 and 2009 we evaluated the abundance of adults of Melolontha hippocastani Fabr. and Melolontha melolontha (L.) cockchafers in four forest regions of the Czech Republic. During this period each of the evaluated localities was hit twice by heavy swarming. The course of swarming, species composition, abundance of the respective tribe, sex ratio during swarming and the correlation between the course of swarming and average daily temperature were monitored by means of a light trap, an automatic meteorological station and observations in the open space; the data were represented in the form of graphs. We evaluated how the trend of the abundance of the particular species developed in the respective localities in order to work out a more specific prediction of the occurrence of the cockchafer in subsequent years and the extent of damage caused by the grubs to forest plantations. Research will continue in 2010–2011.

Storage Pools

Natural forests may be viewed as containing nested nutrient cycles: an "external" cycle mediated by atmospheric processes, a "soil" cycle of litter production and decay, and one or more "plant" cycles involving retranslocation and internal storage pools. The goal of plantation forest management should be to enhance all of these cycles. Stimulating the "external" cycle by adding fertilizer nutrients is likely to increase "soil" and "plant" cycling rates as well. A basic understanding of how these nested cycles are linked can improve the management of nutrients in forest plantations.

Policy Makers

Forest plantations have expanded rapidly in response to financial support from the state and local governments and have had significant positive impacts on rural livelihoods and development in Vietnam, since the late 1980s. This study used net present value (NPV) and internal rate of return (IRR) to examine the economic performance of plantations for three species, Acacia mangium Willd, Eucalyptus (Eucalyptus urophylla S.T. Blake × Eucalyptus camaldulensis Dehn), and Manglietia conifera Dandy, in Bac Kan province. On the basis of an annual discount rate of 6%, the results showed that rural households earned positive financial returns from forest plantations with seven-year rotations. Eucalyptus generated the highest NPV but A. mangium generated the greatest IRR. The plantations were facilitated by financial support from the state, land tenure reforms, and wood exports. The results provide valuable business information and policy implications for both local farmers and policy makers. Since the farmers consider more of the short term and economic return of the plantations, the results provide valuable information for policy makers to apply subsidies and other support to promote plantations with significant ecological and environmental benefits for sustainable development of rural economies.
