Abstract

Mit einjährigen Blühstreifen möchte man die Trachtlücke für Bienen und weitere Bestäuber zwischen Ende Mai und Ende Juli verkleinern und natürliche Gegenspieler von landwirtschaftlichen Schädlingen in die Kulturen locken und ernähren. Für die Etablierung eines optimalen Blühstreifens spielen nebst Mischungsgestaltung und Standorteinflüssen auch die Erfahrungen der Landwirtinnen und Landwirte eine wichtige Rolle. Seit 2015 führen Agroscope, FiBL und HAFL deshalb eine Umfrage in Form eines Fragebogens durch, in welchem die Teilnehmenden Angaben über ihre praktischen Erfahrungen mit Blühstreifen machen. Bis Ende 2020 wurden 299 Fragebogen zu Bestäuberblühstreifen (BBS) eingesendet und ausgewertet. Die Anlage eines BBS erfolgte bei den meisten Befragten mit dem Ziel, Bestäuber und andere Nützlinge zu fördern, Schädlinge zu reduzieren und die Attraktivität für Spaziergänger zu erhöhen. Die persönlichen Beobachtungen der Landwirtinnen und Landwirte zeigten ein positives Bild: Die Mehrheit der BBS lief gut auf, verursachte einen vertretbaren Unkrautdruck sowie einen mässigen Pflegeaufwand und wies eine hohe Abundanz an Blüten und Insekten auf. Die meisten Teilnehmenden waren mit ihrem BBS zufrieden und würden erneut einen solchen anlegen. Einzig die tiefe Beratungsquote und die oftmals suboptimale Auswahl der Saatmischung haben Verbesserungspotential.

Abstract

Floral plantings are promoted to foster ecological intensification of agriculture through provisioning of ecosystem services. However, a comprehensive assessment of the effectiveness of different floral plantings, their characteristics and consequences for crop yield is lacking. Here we quantified the impacts of flower strips and hedgerows on pest control (18 studies) and pollination services (17 studies) in adjacent crops in North America, Europe and New Zealand. Flower strips, but not hedgerows, enhanced pest control services in adjacent fields by 16% on average. However, effects on crop pollination and yield were more variable. Our synthesis identifies several important drivers of variability in effectiveness of plantings: pollination services declined exponentially with distance from plantings, and perennial and older flower strips with higher flowering plant diversity enhanced pollination more effectively. These findings provide promising pathways to optimize floral plantings to more effectively contribute to ecosystem service delivery and ecological intensification of agriculture in the future., Floral plantings are promoted to foster ecological intensification of agriculture through provisioning of ecosystem services.
