“…It is not only the Matoa trees that are endangered by the local wisdom of the local people, but also other species may die if the trees are felled down. The fluctuation of the growth of the population may result from the gap of the crown because of the felling of the trees (Fayolle et al, 2014;Kuswandi &Murdjoko, 2015). So, it is necessary to introduce a new method in harvesting Matoa fruits, such as by directly picking the fruits without felling the Matoa tree down.…”

The detailed causal factors of flood have not been established, whether because of the damage of upper watershed, sedimentation resulting in shallow river, forest conversion, the decrease in abundance and structure or high rainfall. The study aimed at finding out the species diversity and structure of the limited production forest (LPF) from the seedling to the tree stage of Arui watershed in Manokwari district. The species diversity was determined based on Shannon-Wiener index, while vegetation structure was determined based on Importance Value Index. There were totally 92 plots of samples drawn using systematic sampling. The results of vegetation analysis showed that there were 174 species of 43 families with the species diversity of 1.5-1.8 that was categorized as moderate. The four dominant species that were always found in seedling, sapling, pole and tree stages included: Pometia pinnata, Teijsmanniodendron bogoriense, Chisocheton ceramicus, and Horsfieldia irya. The conversion of the LPF into non-forestry sector for the purpose of accelerating development must be reviewed by considering hydrology, land, biodiversity, and social and regional aspects in order to prevent and to reduce flood in the coming days.

“…This diameter distribution shape is similar to that of natural primary forest. This is a typical feature for uneven-aged and multispecies stands in tropical rainforests as studied by Kang et al (2014), Nguyen et al (2014), De Lima et al (2016) and also in logged forest (Kuswandi and Murdjoko 2015).…”

Matius P, Tjwa SJM, Raharja M, Sapruddin, Noor S, Ruslim Y. 2018. Plant diversity in traditional fruit gardens (munaans) ofBenuaq and Tunjung Dayaks tribes of West Kutai, East Kalimantan, Indonesia. Biodiversitas 19: 1280-1288. Munaans are traditionalfruit gardens of the Benuaq and Tunjung Dayaks tribes of West Kutai, East Kalimantan, Indonesia. This research was conducted inMencimai, a Benuaq Dayak’s village and Sekolaq Darat, a Tunjung Dayak’ village. A 1.0 ha plot of old munaan lou (lembo lamin) inMencimai Village was used as representative study site for Benuaq ethnic traditional fruit garden and 1.0 ha plot of old munaan luuq(lembo lamin) in Sekolaq Darat Village as the study site representing Tunjung ethnic fruit gardens. Index of diversity was calculated byusing Shannon-Wiener (H') formulae and evenness by using Pielou. Species richness in munaan lou of Mencimai was 174 and munaanluuq of Sekolaq Darat was 165, which consisted of trees and understorey plants such as tree saplings, seedlings, shrubs, herbs, bamboos,lianas, and rattans. Diversity indices (H’) for all stage of plants within both munaan lou of Mencimai and munaan luuq of Sekolaq Daratwere 4.45 and 4.21 with the evenness (E) were 0.86 and 0.82 respectively. The common species of fruit trees found in munaan lou ofMencimai were Lansium domesticum, Durio zibethinus, Nephelium sp., Artocarpus integer, Nephelium lappaceum, Baccaureamacrocarpa, and Baccaurea edulis. Meanwhile, D. zibethinus, L. domesticum, Artocarpus anisophyllus, A. integer, Nepheliumuncinatum, and B. macrocarpa were the common fruit species in munaan luuq of Sekolaq Darat. The munaans serve many functions in thelocal context, and the local communities mainly use them as sources of fruits, wood, medicinal plants, tools, and legality of land tenure.

“…Similarly, the population of stands in post-selective logging was rising despite the fact that a gradual decline was in the beginning after logging. Those fluctuations of population growth rate resulted possibly from the gap of the canopy by logging (Fayolle et al, 2014;Kuswandi & Murdjoko, 2015). This condition can trigger all vegetation to compete each other in order to get sunlight (Win et al, 2012).…”

“…This is in line with previous research for other species in this area that after selective logging e.g. Vatica rassak, Syzygium sp., Litsea timoriana and Canarium asperum (Kuswandi & Murdjoko, 2015) were growing as well. In contrast, previous research showed that some tree species like Actinodaphne nitida and Blumeodendron sp did not show a rapid growth, even though there was an optimistic prediction that those species would recuperate from damage by logging (Murdjoko, 2013).…”

“…The southern part of Papua is a lowland tropical rainforest and some parts of them have been experiencing logging for about over the past decades (Kuswandi & Murdjoko, 2015;Kuswandi, 2014;Murdjoko, 2013). Hence, this leads to alterations of floristic composition, structure as well as the growth of vegetation in logged forest as a response to logging impact (de Avila et al, 2015;Sandor & Chazdon, 2014).…”

Tropical rainforest changed in term of structure, composition and population, resulting from logging. One of target trees during logging is Pometia. Our goals of this research were to answer that (1) How were survival, growth, fecundity and population growth rate (λ) of Pometia within remnant stands?; (2) what were driving factors to explain population dynamics of Pometia within logged forest?. Data were derived from three hectares-permanent sample plot (PSP) in logged forest of PT Tunas Timber Lestari. Integral Projection Models (IPMs) were applied to analyze population dynamics. The study showed dynamically that probability of the individuals of Pometia survived in this area did not significantly differ among their size, while stands showed the significant difference between small and large individuals. The growth of both individuals of Pometia and stands varied significantly in different size. The probability of fecundity both Pometia and stands were significantly different among size. The population of Pometia has been increasing for about a decade as the population of all stands was growing as well. Moreover, the regular documentation of species composition and structure before and after logging is necessary as a control of biodiversity. Therefore, a proper protocol to monitor the biodiversity should be designed by government and disseminated it to logging companies.
