Abstract/Contents:"The faunistic variety of turf can be considerably promoted by increasing the plant variety of native plants adapted to the site. Since it is not only the composition of the species which is of importance but also the areal structure of the stock, the management should be adjusted to the biology and particularly to the development cycles of the insects and other invertebrates. Of great value is moreover a structuring of more extensive areas in the form of a mosaic, so that more ecological niches can be established." It is estimated that for every single kind of wild plant, ten insect species are dependent upon it. Many flowers have evolved to be specifically pollenated by butterflies alone, so the mere planting of any wild flower, or the mere inclusion of butterflies into an area where no flower exists from which they can get their needed nourishment is bound to fail. The amount of wild flower species needed to maintain merely a single nest of wild bees is enormous. Each mowing resembles a catastrophe; depending on the mower used, many of the insects either escape, or are mowed down along with the grass. Due to the needed room and plant diversity, a single island of vegetation is barely enough; far better is a net of closely located vegetation, to enable the insects to easily move from one to another. Careful attention to the kinds of wild flowers planted can promote a diverse, healthy insect population as well. The use of rotary mowers should be avoided, and no pesticides should be applied, even high levels of herbicides have proven to severely harm the insect populations.
