Abstract
This study was conducted in Sekelemariam Dry Evergreen Montane Forest which is situated within 37° 27' and 37° 30' east, and 10° 34' and 10° 36' north, near Dembecha Town in west Gojam Zone, North Western Ethiopia. It is characterized by steeply sloped areas with huge Rocky Mountains extended throughout the middle parts of the forest. The aim of this study was to estimate the soil carbon stock potential of the forest. A systematic transect sampling technique was adopted in this study and following these transects plots of 1mx1m (1m<sup>2</sup>) data was taken from the field. The carbon stock density of soil organic carbon was calculated from the volume and bulk density of the soil as V = h× r<sup>2</sup>. The data analysis was conducted using Microsoft excel sheet used as platform in carbon calculations, and SPSS software version 20 to determine the impact of altitude gradient and slope factors on soil carbon stock potential and to compare the relationship between dependent and independent variables. The carbon stock of the SOC showed increasing trend with increasing elevation. In contrast to the elevation, the forest soil carbon stock decreases as increasing slope gradient. Soil laboratory analysis was conducted in Holeta Agricultural Research center to determine the soil organic carbon density and was estimated to be101.56 ± 3.66 t C ha-1. All in all, this study gives estimation of the soil carbon stock in Sekelemariam State Forest.
Highlights
Global warming and climate change arising due to the greenhouse effect / Greenhouse Gas (GHG) emissions resulting from the effects of development activities in various business sectors, including land use, changes in the function and forest allocation, forest and land fires, a decrease in quality of forests from uncontrolled utilization, as well as the burning of fossil energy [17]
Anthropogenic emission of carbon dioxide leads to global warming and climate change affecting the biodiversity and destabilizing food and livelihood security
The soil organic carbon content of this forest has been assessed with respect to different environmental variables like slope and altitude gradients
Summary
The issue of global climate change has become a central issue and concern of the world by all people at local, regional, national and international levels. Global warming and climate change arising due to the greenhouse effect / Greenhouse Gas (GHG) emissions resulting from the effects of development activities in various business sectors, including land use, changes in the function and forest allocation, forest and land fires, a decrease in quality of forests from uncontrolled utilization, as well as the burning of fossil energy [17]. Anthropogenic emission of carbon dioxide leads to global warming and climate change affecting the biodiversity and destabilizing food and livelihood security. Rise in atmospheric CO2 is because of large scale burning of oil, coal and natural gas, which are the energy sources for modern industrial economies and due to deforestation [13]. Forests are one of the major pools of carbon since plants fix atmospheric carbon in the tissues; thereby transform carbon from atmosphere to the biological systems
