Abstract:

Agroforestry offers ecosystem benefits and services such as controlling soil erosion, modifying the microclimate to enhance yield, economic diversification, livestock well-being and production, and water quality protection. Also, agroforestry practices can affect ecosystem services offered by insect pollinators through increased functional and structural diversity in agricultural landscapes. This thesis aimed to assess the effect of modern agroforestry systems in the Czech Republic on the species richness and diversity of insect pollinators. This study was conducted in experimental station Central Bohemia. Insect pollinators were captured in four habitats (Agroforestry tree line, Agroforestry crop line, Open field, and Natural habitat) from May to September 2019. In total, 1,795 insect individuals belonging to 15 families were captured. The families with the highest number of species and number of individuals were: Halictidae, Colletidae, Crabronidae, Pompillidae, and Andrenidae. The highest abundance across all habitats was recorded in mid-July. Species richness and diversity were different in each of the habitats. The agroforestry tree line is a central area of all habitats. The highest species abundance and richness were found in the agroforestry tree line, followed by the agroforestry crop line, the natural close habitat and the open field. The agroforestry crop line was merged with the agroforestry tree line. The agroforestry tree line and the agroforestry crop line being the most similar of all habitats. The lowest values were observed in open field habitats. A well-managed agroforestry system has the potential to sustain a wide variety of native pollinator species Průhonice-Michovky.
