Abandonment of agriculture land and subsequent natural afforestation have been common features of the contemporary Latvian rural landscape, particularly in the period since 1990. This process affects the structure, ecology and visual qualities of the landscape. The study examines spatial characteristics of afforestation in relation to various environmental factors. The study was conducted in the central part of Latvia, where there is abundant abandoned agriculture land and a great variety of spatial afforestation patterns. The most typical patterns in this area were linear, mosaic, and continuous afforestation, as well as development of afforestation from the forest edge. The results of the study show that the spatial patterns of natural afforestation of abandoned agriculture fields can be very diverse, and do not follow the classical secondary succession model. Afforestation can be delayed by a dense cover of herbaceous vegetation for a period of up to 20 years. There are many interacting factors that affect succession and development of afforestation patterns, such as soil properties, size and configuration of fields, previous land use and also the random nature of plant colonization by seed. Further studies on afforestation patterns would help to understand better their ecological, economic and social effects as well as to determine optimal solutions for the use of abandoned agriculture land.
