Course abstract

Aim of the course is to provide students with basic information on the achievements, newest results and perspectives of forest tree breeding to improve parameters of forest stands. Master students will gain information about the prognosis of climate changes in Latvia, expected negative influence to forests and adaptation possibilities with emphasize on role of genetic factors.

Learning outcomes and their assessment

During the course students gain knowledge about predicted changes in climatic conditions and there potential negative influence on forest stands in territory of Latvia. After the accomplishment of the course student are competent to recommend ways of forest management aiming at improvement of adaptation capacity of forest stand. Students are skilled to evaluate and quantify effect of various forest management decisions on carbon balance and stability of stands.
