Our research was based on data obtained from a questionnaire administered in 2005 distributed to 80 farms in Wigry National Park in northeastern Poland. The questionnaire concerned agricultural production and the attitudes of farmers for future plans, especially connected with sustainable development, e.g. organic farming. The data were analyzed using a classification based on two-dimensional criteria: farm size (in ha of UAA) and type of production, as well as multivariate statistical methods such as cluster analysis and principal component analysis. From the analyses, six groups of farms were identified according to the characteristics of their farming systems, and the relationships between the examined variables were evaluated. A large percentage of the farms (approximately 32%) were classified as units that served primarily social functions, with an average area of approximately 10 ha. The other groups of farms identified were characterized by medium- or lowintensity agricultural production. Only one group, consisting of approximately 13% of the farms, performed intensive cattle production (LSU above 1 per ha) and used higher levels of fertilization (above 100 kg NPK per ha).
