Abstract

Agroforestry or tree crops in West Sumatra is called parak, it mostly related to rural and farmers but at some developing areas the parak is still existed with a high potential changes in structure and floristic composition due to commercial orientation. To explore the possible changes of tree community in such developing areas, 11 of 20x20 meter plots were established across parak areas in peri-urban site in Lubuk Alung district, Padang Pariaman Regency, West Sumatra Indonesia, aimed to specifically investigate tree density, stand basal area, spesies distribution and other ecological atributes of the species. We found 24 tree species from 306 trees within 0.44 ha or about 695 tree per ha. Durio zibethinus was the biggest trees, found as a top canopy but few in number and spreaded quite widely across the areas, followed by some other species such as Cocos spp., Areca catecu, Garcinia spp., while small trees, high density but only spreaded at some places was represented by Theobroma cacao. Many species and the structure were typically agroforest that vary in canopy level and economic functions except some species which may be additionally planted to suit the needs of peri-urban community.

Abstract

Microhyla gadjahmadai was first described by Atmaja et al. in 2018. For the newly described species category, there is not much information explaining this species and there has been no further research after this species was described, especially in West Sumatra. This study aims to provide information on variations in the morphological characteristics of M. gadjahmadai in West Sumatra, through morphological and morphometric analysis of 8 samples (1 adult male and 7 adult females) found in Puncak Anai (Dempo Anailand), Kanagarian Guguak, District 2x11 Timber Planting, Padang Pariaman Regency, West Sumatra. This study used the Visual Encounter Survey (VES) method. The result of the present study shows that no significant morphological differences between the holotype and paratype of Microhyla gadjahmadai and other specimens from West Sumatera. However, the present study reported that the morphological variations of this species.

Abstract

Mammal inventory is a survey activity to find mammal species that exist in a certain area at a certain time and point. The existence of mammals in a forest area helps restore forest conditions through their role as natural predators and seeds dispersing. Nagari Forest is one of the efforts to maintain the existence of forests and biodiversity that have ecological, economic, socials and cultural benefits. The aim of this study was to determine the types of mammals found in Pondok Parian Nagari Forest, Lunang based on the results of camera trap recordings. This research is descriptive study, conducted from July 2022 to January 2023. Located in Pondok Parian Nagari Forest, Lunang, West Sumatra. Data collection using the camera trap method. The data obtained was analyzed and then arranged into the table consisting of orders, famili and species. The camera trap succeeded in documenting 19 species of mammals belonging to 14 families and 6 orders. Those identified species were Tapirus indicus, Capricornis sumatraensis, Muntiacus muntjac, Tragulus napu, Cuon alpinus, Neofelis diardi, Prionailurus bengalensis, Pardofelis marmorata, Helarctos malayanus, Martes flavigula, Hemigalus derbyanus, Paguma larvata, Viverra tangalunga, Arctictis binturong, Hystrix brachyura, Macaca namestrina, Presbytis melalophos, Macaca fascicularis, Echinosorex gymnure.

Abstract

Nyamplung (Calophyllum inophyllum L.) is a key coastal species with both ecologyl and economic importance. The tree, is highly recommended for coastal zone restoration, but availability of the seeds and seedlings is less known.This study aimed to investigate flowering/fruiting phenology as well as natural regeneration availability across different in coastal zone of  Padang Pariaman Regency. Weekly phenological observations and regeneration stock measurement were conducted from September to December 2025i, with 34 observed trees in the sites that ranged from ;ow to high land use level. Results showed that most trees were found flowering in September, but it was declined following the increasing of fruiting event at mid to end of October and number of the fruiting trees were declined until end of December. These flowering and fruiting phenology among the landuse types showed a similar pattern with only little variation. In general 0.12 seedlings/m², while tourism areas showed the lowest 0.03 seedlings/m² in the highest disturbed. And is was negatively correlated with distance fron the mother tree(p0.05). This study a range of flowering and fruiting phenology in Padang Pariaman Coastal areas with small variation of the phenology between landuse types, as well as variation in regeneration stock of C. inophyllum across the areas.

Abstract

Nyamplung (Calophyllum inophyllum L.) is a coastal plant species that plays an important ecological role in protecting coastal areas from abrasion, reduce the impact of sea winds, and maintain the stability of coastal environments, while the tree is economically potential as vegetable oil sources for biodiesel. In Padang Pariaman Regency, Nyamplung is also knows as Pinago, the trees are found growing in the coastal areas, both naturally and through planting, but it is still remain unknown the current spatial distribution and the local habitat conditions. This study aimed to investigate the spatial distribution and habitat characteristics of Nyamplung in the coastal area of Padang Pariaman Regency. Field observations were conducted for recording coordinates location of each Nyamplung tree, measuring the diameter at breast height (DBH) and canopy cover, and determining habitat characteristics. The spatial distribution  was analyzed using ArcGIS, while the habitat conditions and the population structure were analyzed in terms of linear regression. The results showed that Nyamplung was distributed partly or clustered at three specific site in  the coastline. Most of the site was sandy habitat with very thin layer of top soil and the trees were moslty exposed to full sunlight. The trees were varied in size, ranged from 2-62 cm dbh, with crown cover ranged from 5-600 m2, and these two variables were positively correlated. This study showed a limited number of Nyamplung trees in the coastal of Padang Pariaman, with less damage of community to canopy. Planting of Nyamplung in this area for a wider positive impact.

Abstract

There are national regulations on conservation of wildlife in Indonesia, but the implementation has not been optimum due to lack of monitoring by the government. This program was trying to initiate local participative on conservation of wildlife, specifically initiating a village constructing their own regulation or local custom for sustainable natural resources management. The program was conducted in Singgalang village Tanah Datar Regency West Sumatra, with multi local stakeholders belong to customary holders, tourism leading group, the official village staffs, women association and schools across the village were involved. The program was officially openned by vice Bupati of Tanah Datar Regency, then it was followed by seminar with Yayasan SINTAS Indonesia for biodiversity richness and the problems, and completed by PAGARI for local custom implementation. The participants were excited with the seminar and took various necessary messages. This provided great insight to let the local stakeholders create their local custom
