The United Nations General Assembly declared 2011–2020 the United Nations Decade on Biodiversity, with the goal of significantly reducing biodiversity loss worldwide.
Selecta one has been involved in the project “Flower island – flowers for pollinators in the city”. The project is a joint afford of the Heidelberg State Research Institute, the Regional Institute for Apiculture of the Hohenheim University, Selecta one (our employees Sebastian Mainz and Domink Losert were mainly engaged) and Floricultz to contribute to the conservation of Biodiversity. It has been awarded as an official project of the United Nations Decade on Biodiversity at February 13, 2020 with Andrea Dohm attending the presentation of the certificate as a representative of Selecta one.
The project partners jointly developed measures to promote the biodiversity in urban space. At 14 locations in Stuttgart – from densely populated to open habitats – field trials recorded the pollinators’ approach to exemplary plantings. Helpers counted in detail which pollinator prefer which plants. This was done about 20 times per season for two weeks. Wild and honey bees account for the largest share, but also wasps, hornets, hoverflies, butterflies and folder act as a pollinator.
Essentially, this project had the goal to analyse the meaning of bedding and balcony plants as a food source for insects, especially bees and possibly deduce information about “bee friendly” varieties for breeding. Besides single crops and varieties it was also about plant combinations and to see the influence of size and location. Pelargonium, Dianthus and Verbena had been approached relatively little. Pollinators prefer Bidens, Lavandula and Salvia.
One main conclusion is that, bedding and balcony plants can’t compete with wild plants regarding “bee friendliness” but they contribute as an important in-between food source while wild plants do not flower. Furthermore, every little bedding or container was found by bees, especially in urban spaces like inner cities. A combination of different plants is advisable to offer food sources for different insect groups for the longest possible period.
