THE CHARACTERISTICS OF FOREST UNDERSTOREY IN MYRTILLOSA MEL. FOREST SITE TYPE IN LATVIA
Abstract
Forest resources are the most significant natural wealth of the state of Latvia. According to the data of the 2nd stage of the forest resource monitoring for 2014, Latvia has 3575 thousand hectares of forest land comprising 55.3 percent of the total territory of Latvia, while the total timber stock estimated at 668 million cubic meters. Each forest stand has a certain amount of undergrowth and understorey ? small dimensions woody plants (shrubs) which is few researched until now. The most precise determination of the amount of energy wood in Latvian forests, would be of great benefit to Latvian economy. The research data were collected in forests of Jelgava Forest District of Agency ?Forest Research Station? in Latvia. The research was carried out in several forest subquarters of forest site type Myrtillosa mel. by establishing of circle shaped sample plots with an area of 25 m2. That was concluded that the volume of the potential energy wood in understorey in Myrtillosa mel. forest site type conditions is significant reaching 12 tons per hectare and it is advisable to use it as a raw material for energy production together with felling residues. However, it is necessary to evaluate the technical and technological capabilities from the economic point of view in each particular case.
