The objective of the present paper is an analysis of the impact of shelterbelts on adjoining fields basing on the analysis of the species diversity and patrolling intensity of the soil surface by the two mainly predatory, abudantly represented arthropod group - spiders and carabid beetles. In the shelterbelt - managed areas the biomass of patrolling arthropods was lower inside the fields than at the field margins and in the shelterbelts. The biomass of patrolling arthropods and individual weight increased with the age of strips
