Biomass is the world's fourth largest source of energy after oil, coal and natural gas. Biomass is the largest and currently the most important renewable energy option and can be used to produce various forms of energy. As a result, biomass, together with other renewable energy options, is able to provide all the energy services needed in today's society, both locally and globally. Among many other aspects, the renew-ability and versatility of biomass as an energy source is also an important advantage. In addition, compared to other energy sources, biomass is widespread around the world.
The aim of the study is to evaluate the energy wood resources available in the understorey and undergrowth of drained forests in Latvia. There are the resources of undergrowth and understorey of Agency "Forest Research Station" in Jelgava Forest district used, as well the data of State Forest Resources Monitoring realized by Latvian State Forestry Research Institute "Silava". The study estimates the amount of biomass to be obtained in Myrtillosa mel. and other drained forest site types. The mass models are designed to calculate the mass of absolutely dry wood for State Forest Resources Monitoring data. The results of the study conclude that a higher amount of biomass of undergrowth and understorey is obtained in stands with lower density. Countrywide, there in the drained forest site types, most biomass is obtained in Mercurialiosa mel. forest site type - in average 10.55 t ha-1 and in Oxalidosa turf. mel. - in average 7.96 t ha-1. The the lowest biomass is found in forest site type Callunosa turf. mel. - in average 0.7 t ha-1 and in Callunosa mel. - in average 0.18 t ha-1. |
