Abstract

Tapir is a large endemic mammal on the Sumatra island, this animal is prioritized for conservation because it is categorized as an endangered species. The population is at risk of extinction >20% over a 20 year period, when no conservation efforts are made in accordance with their habitat. Tapirs can live in swamp habitats, lowlands, mountains, hilly forests, secondary forests, shrubs and palm plantations. All of the most important types of habitat are the availability of food, water and shelter. A habitat that is suitable for the survival of the tapirs is needed, such as the availability of sufficient food and an environment that supports tapirs to breed. This research aims to find out the characteristics of Asian tapir habitat (Tapirus indicus) in several types of primary forest vegetation, secondary forests and shrubs in the working area of Resort Lahai SPTN II Belilas Bukit Tiga puluh National Park and surrounding areas in Riau Province. This research was conducted using purposive sampling method by determining the characteristics of tapir habitat. The characteristic of tapir habitats in TNBT and surrounding areas in the three vegetation are the closure of tree headers in the bush 0%, secondary forests 3.63%-54.21% and primary forests 4.37%-85.66%. Availability of feed plants in primary forests 3.03%-83.33%, secondary forests 39.13%-100.00%, shrubs 50.00%-100.00%. The characteristic of tapir habitats in primary forests, Secondary forests and shrubs include low land with topography ramps up to rather steep, distances with natural forests from primary forests are 633.54 m-1,155.00 m, secondary forests 1,253.32 m-1,791.76 m and shrubs 1,539.76 m-1,985.14 m. Distance by river from secondary forest 100.84 m-325.95 m, primary forest 126.58 m-290.99 m and shrub 111.33 m-356.04 m.

Abstract

The Indonesian government is committed to reducing carbon and greenhouse gas emissions through the Forestry and Other Land Uses (FOLU) Net-Sink 2030 scheme. Efforts that can be made to support the FOLU Net-Sink 2030 is by knowing the carbon storage potential in a forest area. This research aims to calculate the amount of potential biomass carbon storage in the talang forest. The methods used in this research are non-destructive sampling and destructive sampling. The method with destructive sampling for seedlings, understorey and litters, while for saplings, poles, trees and necromass with non-destructive sampling method. The calculation results showed that carbon stocks were trees (77.76 tons/ha), poles (9.56 tons/ha), saplings (7.99 tons/ha), seedlings and understorey (0.65 tons/ha), litters (1.20 tons/ha) and necromass (2.39 tons/ha). Aboveground carbon storage in the talang forest was found to be 99.56 tons/ha. The total aboveground carbon storage potential of the gutter forest was 7,933 tons of carbon.

Abstract

Timor deer (Cervus timorensis) is the second largest tropical deer after sambar. Compared to other Indonesian tropical deer, the timor deer (Cervus timorensis) is unique in that it is a deer that has many sub species, with a wide spread area. Timor deer (Cervus timorensis) are widely bred in various locations because they have high economic value, in which all parts can be utilized. The potential of timor deer can be developed as part of environmental services that have high value as recreational objects. The purpose of this study was to determine the potential of timor deer feed (Cervus timorensis) at the University of Riau and determine the production of timor deer feed (Cervus timorensis) at the University of Riau. The study was conducted at a prospective location for timor deer breeding (Cervus timorensis), Riau University campus covering an area of approximately 2.07 ha. Sampling was carried out using a plot of 41 plots, with a size of 1 m x 10 m. Riau University has potential as a location for timor deer breeding (Cervus timorensis). Production of all types of deer feed in captive breeding sites amounted to 2,878.67 gr/m.
