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

Vegetation plays an important role in overcoming hydrological processes in an area, including protected forest areas. Changes in vegetation cover in protected forests will affect the water flow of a watershed ecosystem. However, there is still a lack of information about the vegetation structure of the Bukit Barisan I protected forest, so it is important to do research to find out the vegetation that makes up the Bukit Barisan I protected forest, the Lubuk Paraku Sub-watershed in Lubuk Kilangan District, Padang City. The research was conducted from November 2022 - March 2023. This type of research is descriptive using a survey method. For field data collection, the single plot method was used in 2 areas, the natural forest area and the forest adjacent to the garden. In each area, 3 single plot plots were made, 2 x 2 m plots for undergrowth and seedlings, 5 x 5 m for saplings, 10 x 10 m for poles, and 20 x 20 m for trees. Found at the seedling stage 145 individuals from 20 families, saplings 51 individuals from 10 families, pole stage 29 individuals from 10 families and tree stage 48 individuals from 12 families. The most individuals at the seedling level are included in the Araceae family, the most individual saplings and trees are included in the Moraceae family, the most individual pole stages are included in the euphorbiaceae family.

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

Parak is the most common agroforestry site, especially on dry land in the form of gardens or fields. The term parak is only used by people in West Sumatra, and is a release of the ecosystem between agricultural land and forests. Parak has many different species, with many trees, and a complex and layered vertical structure. The purpose of this study was to determine the structure and composition of vegetation in the Parak ecosystem in Nagari Lubuk Pandan, 2X11 Enam Lingkung District, Padang Pariaman Regency, West Sumatera. The method used is a field survey method by making observation plots measuring 10m x 10m for trees and sub-plots 5m x 5m for poles, 2m x 2m for undergrowth placed in the parak area in Nagari Lubuk Pandan District 2X11 Enam Lingkung, Padang Pariaman Regency, West Sumatera. The results of this study obtained the highest INP value, namely the type Durio zibethinus L. with an INP value of 32.57. The index value of hostility in the parak ecosystem in Nagari Lubuk Pandan is high and community stability is high with a diversity index of 3.50. The composition of plant species in the parak ecosystem consists of 61 plant species with 35 different families.

Abstract

Parak is one of the transitional ecosystems from agricultural land and forests, it can also be called agroforestry. Parak agroforests produce a variety of forest products that are both for sale and for household needs including construction timber, firewood, and non-timber products such as fruit, forest vegetables and medicines. The purpose of this study was to determine the community structure of trees in the Parak ecosystem in Tanjung Raya District, Agam Regency. This type of descriptive research using field survey methods. Data collection was carried out at 4 locations by making 10 observation plots at each location in Tanjung Raya District, Agam Regency. At each location area a 20x20 plot is made to measure the trees contained in the plot. The results of this study obtained data that there were 31 species with a total of 959 individuals. The highest IVI value at location 1 Cinnamomum verum was 61.45. The highest IVI was at location 2 Myristica fragrans of 86.08. The highest IVI at location 3 Cinnamomum verum was 66.63 and at location 4 was obtained by Durio zibethinus of 56.44. The species diversity index (H') at location 1 was 2.29, at location 2 was 1.59, at location 3 was 1.68 and at location 4 was 2.78. While the overall obtained is 3.31. The species diversity index (H') at locations 1,2,3 and 4 belongs to the medium category, and overall belongs to the high category.
