In the framework of the evaluation of ecological measures promoted by the Swiss Government, a botanical survey was undertaken in three regions in 1997 or 1998. Plant species per 100 m2 were investigated in 88 meadows under different cultivation regimes (from extensively to intensively cultivated).<br>With mean of 15 to 27 spexies per region and type of meadow diversity was generally low. Meadows registered as ecological compensation areas showed a trend to a higher number of species. The influence of the region, however, was greater than that of the cultivation regime. In regard to biodiversity, a large number of meadows registered as ecological compensation areas could not be distinguished from more intensively cultivated ones.
Grass-based beef production is markedly less productive than intensive year-round indoor-housing system-based production. Agroscope experts therefore studied how grass-based farms can produce both economically and in an ecologically sound manner.
Orchard crop spraying using unmanned aerial spraying systems commonly referred to as drones can lead to drift, posing a risk to residents and bystanders. The study shows that the risks arising from this are taken into account by the current registration process.
Trials conducted by FiBL have shown that conversion to organic farming also promotes endangered Red List species such as the carabid beetle species Amara tricuspidata. This species and other species consume seeds of forbs and grasses and thus supports natural weed control.
