The quality and connectivity of ecological compensation areas (ECA) may be improved by habitat connectivity projects. The effects of such a project on the distribution of field cricket (Gryllus campestris) and large gold grasshopper (Chrysochraon dispar) were studied in the Plain of Wauwil (canton of Lucerne). The presence of both species, as well as eight habitat variables were mapped. The connectivity of ECAs was vital for both species, especially links to ECAs where the species had already settled. Field crickets favoured short vegetation and meadows farmed at a medium or low intensity; they avoided damp sites with a dense sward of tall plants. Moreover, the probability of encountering field crickets increased with field size. For the large gold grasshopper it was important that the vegetation was not mown on part of the area and remained undisturbed over winter. We show that insects with a restricted mobility like the field cricket and the large gold grasshopper profit from habitat connectivity projects. Depending on the species’ requirements, however, specific factors have to be considered.
Agroscope has developed a scoring system for plant protection in vegetable crops. The system enables the creation of incentives for reducing the use and environmental risks of plant-protection products and promoting preventive and non-chemical measures.
Many consumer goods contain activated carbon, which can be contaminated with pollutants like polycyclic aromatic hydrocarbons (PAHs). Agroscope showed that current analytical methods and legal bases used to address PAH content are incomplete.
Dry summers can see a loss of up to 25% of total Swiss roughage production. This is because grassland yields are strongly correlated with summer drought, as shown by a new analysis conducted by Agroscope and the Swiss Farmers’ Union.
