Spatial Distribution and Temporal Change of Carbon Storage in Timber Biomass of Two Different Forest Management Units

Abstract

Forests make up large ecosystems and can play an important role in mitigating the emissions of CO2, the most important greenhouse gas. However, they are sources of atmospheric carbon when they are disturbed by human or natural causes. Storage of carbon through expansion and adaptive management of forest ecosystems can assist in reducing carbon concentrations in atmosphere. This study proposes a methodology to produce spatially explicit estimates of the carbon storages (aboveground plus belowground) depending on land use/cover changes in two different forest ecosystems during various periods. Carbon storages for each forest ecosystem were projected according to inventory data, and carbon storages were mapped in a geographic information system (GIS). Results showed that total carbon stored in above and belowground of both forest ecosystems increased from one period to other because of especially increase of productive forest areas and decline of degraded forest areas as well as protection of spruce forests subject to insect attacks.

Forest cover change and fragmentation using Landsat data in Maçka State Forest Enterprise in Turkey

“…The causes are mainly mismanagement, heavy grazing of pasture land adjacent to forest areas, illegal use of forest resources and insect attacks and ecosystem dynamics. The impacts are loss and conversion of some natural forest types, increase of productive forests, exposure of some lands to soil erosion and carbon emission to the atmosphere (Sivrikaya et al 2007b). …”

Edades óptimas de corte en bosques de álamos híbridos incluyendo captación de carbono: Un estudio de caso en Turquía

“…También existen algunos estudios que analizan los efectos del uso de suelo y los cambios en la cubierta sobre las cantidades de captura de carbono de los ecosistemas forestales (Kadıoğulları & Karahalil 2013;Keleş, Kadıoğulları, & Başkent, 2012;Sivrikaya, Keleş, & Çakır, 2007). Sin embargo, la determinación de las edades óptimas de corte en el manejo forestal,…”

“…There are also some studies to analyse the effects of land use and land cover changes on carbon sequestration amounts of forest ecosystems (Kadıoğulları & Karahalil 2013;Keleş, Kadıoğulları, & Başkent, 2012;Sivrikaya, Keleş, & Çakır, 2007). However, determining optimum cutting ages in forest management including multiple forest ecosystem values has not yet been sufficiently appraised in the scientific literature in Turkey.…”

Case Study of the Effects of the Japanese Verified Emissions Reduction (J-VER) System on Joint Forest Production of Timber and Carbon Sequestration

“…Recently, the benefits of carbon sequestration by forests have been highlighted and carbon sequestration has been measured throughout the world: in the United States (Sakata 2005;Calish et al 1978;Foley et al 2009;Ehman et al 2002;Im et al 2007), Europe (Backèus et al 2005;Liski et al 2001;Matala et al 2009;Pohjola and Valsta 2007;Sivrikaya et al 2007;Kaipainen et al 2004;Seidl et al 2007), Canada (Hennigar et al 2008;Thompson et al 2009), Oceania (Campbell and Jennings 2004) and Asia (Ravendranath 1995;Han and Youn 2009). Forests not only have economic value through the production of commercial timber, but they also have other values to society including acting as carbon sinks, supporting biodiversity, and providing water protection (Pukkala 2002).…”
