Abstract<br />

Afforestation of the former agriculture l<strong>and</strong> is one of the most typical trends of the<br />

contemporary Latvian rural l<strong>and</strong>scape. The study examines development of l<strong>and</strong>scape<br />

ecological succession, its spatial character <strong>and</strong> influencing environmental factors within<br />

ab<strong>and</strong>oned agriculture l<strong>and</strong> in Vidzeme, central part of Latvia. The study area comprises<br />

a great variety in the spatial dynamics of the ecological succession. Character of the<br />

ecological succession is influenced by various factors like soil fertility, moisture <strong>and</strong><br />

light conditions, species composition of surrounding forest, former l<strong>and</strong> use etc. The<br />

study aims to assess impacts of these factors on dynamics of afforestation process in<br />

order to predict its future development.<br />

Keywords: ab<strong>and</strong>onment, afforestation, l<strong>and</strong>scape ecological succession, environmental factors<br />

1. Introduction<br />

L<strong>and</strong> ab<strong>and</strong>onment <strong>and</strong> related natural afforestation process is typical feature of contemporary<br />

l<strong>and</strong>scape in marginal areas all over the Europe <strong>and</strong> most probably this trend will last for the<br />

coming years - modelling of l<strong>and</strong> use development in Europe until 2030 shows decline of<br />

agricultural l<strong>and</strong> as one of the major factors influencing European l<strong>and</strong>scape in future (Stoate et<br />

al 2009). In Latvia afforestation process has been noted from the beginning of the last century,<br />

resulting from frequentative change of political <strong>and</strong> economic situation – if in 1935 forest<br />

occupied ca. 27 % of the l<strong>and</strong> area, than by 2008 its area has almost doubled, reaching ca. 50 %<br />

(Ministry of Agriculture 2009; Nikodemus et al. 2005). During the last ten years forest area has<br />

increased mostly due to natural afforestation, twice exceeding artificial afforestation. This is<br />

related to extensive l<strong>and</strong> ab<strong>and</strong>onment after regaining of independence from Soviet Union in<br />

1991 <strong>and</strong> the following collapse of the collective farming system, urbanisation process <strong>and</strong> l<strong>and</strong><br />

reform (big share of the agriculture l<strong>and</strong> was retrieved by the former l<strong>and</strong> owners, presently<br />

living in city <strong>and</strong> having not much interest in farming).<br />

In the recent years l<strong>and</strong> ab<strong>and</strong>onment has become an important issue in scientific research,<br />

questioning what are the factors influencing this process, how it impacts the l<strong>and</strong>scape structure<br />

<strong>and</strong> biodiversity as well as the potential of ab<strong>and</strong>oned l<strong>and</strong> for use of natural resources or<br />

restoration of habitats. Socio-economic <strong>and</strong> political factors driving the marginalisation process<br />

<strong>and</strong> l<strong>and</strong> ab<strong>and</strong>onment are well studied. However little is known about impacts of<br />

environmental factors on ecological succession process <strong>and</strong> related changes in the l<strong>and</strong>scape<br />

spatial structure. Some authors argue that role of these factors is less significant compared to<br />

socio-economic factors (Łowicki 2008; M<strong>and</strong>er et al. 2004).<br />

Though one should bear in mind that once the l<strong>and</strong> has been ab<strong>and</strong>oned, the ecological<br />

succession process takes over <strong>and</strong> environmental factors becomes determinant. The course of<br />
