Abstract

Forests play an essential role as source and sink in global carbon cycle. Development and other human induced activities have led to degradation of forest land, and ultimately, it results in loss of biodiversity and increases concentration of CO₂ in atmospheres. Therefore, there is urgent need to estimate regional and national level carbon stock for making forest-based policies and strategies for mitigation of CO₂. Variable and periodic information is available on biomass and carbon stock of Gambo Natural Forest. This review presents a systematic review on the Biomass Carbon Stock Estimation Options for Trees and Forests Resources: Within and Around Mago National Park, Southern Region of Ethiopia. In order to review and gain information from existing research on types of forest, basal area, biomass/carbon stock, sequestration pool in different forest ecosystems of Mago National Park, a literature search was carried out during January 2022 to October 2022 using Web of Science, Google Scholar Citation, Research Gate,IPCC, United Nations Framework Convention on Climate Change (UNFCCC) and REDD+ report, offline journals, book chapters, , government scientific reports, Forest Survey data, Botanical Survey data, as well as reports published by Ministry of Environment, Forest and Climate Change. The review is limited to in and around Mago National Park forest ecosystem in relation to above and below biomass and carbon stock estimations. Formulating allometric equations for all woody plants in Ethiopia is quite desirable for accurately quantifying the biomass and carbon stock of forests to achieve accurate national and international reporting of carbon dioxide emission inventories. Depending on this in Ethiopia several study undertaken regarding allometric equation for biomass estimation, but it is not as forest resource of the country. Most of the study undertaken was depend on semi-destructive method which is not accurate as destructive measurement.
