With the splendor of the meadows, the diversity of the Moths
honey bees disappearing have it good: at the Latest since the Swiss Director Markus Imhoof six years ago, his Film “More Than Honey” about the global bee die mounted in the cinemas, you’ll get attention for sure. Now a high-ranking politician to fly on the topic. 20. May 2018 is not made for the first time, a world bienentag on the Brummer’s attention, even though they are home to most of the countries originally.
hardly anyone noticed, meanwhile, a possibly larger insects drama – the disappearance of the butterflies.
Where once fire red, sky blue and bright yellow Butterflies across the meadows and fields of led, there is today a green wilderness. The Ecologist Josef Reichholf researched for almost 50 years, the domestic insect world. His status report on behalf of the German wild animal Foundation reads as a tragedy: Since the mid-70s, the number of diurnal is pointed of species to 73 percent. The number of moth species and their frequency has halved since the early 80s.
80 percent of field bird species, threatened
Reichholf, 73, is a figurehead of the environmental movement, wrote to Munich’s two universities as a Professor taught, and more than 30 popular science books. In 1969, he earned his PhD in water butterflies, which spend part of their life, or sometimes the whole under water. Since the end of the 60s the biologist begins with light moths to fall in his Southeast Bavarian home at the Inn, and other Places. The special feature of his method: The butterflies and other attracted insects to stay alive and be able to flutter to the Count.
Not only for optical reasons the Disappearance of the Butterfly is a tragic loss, says Reichholf: “butterfly caterpillars are the main food source of many bird species.” With the Lack of Moths and other insects, more and more birds will disappear. Hatched in 1991, around 300,000 lapwing pairs in Germany, there are now about 100,000. Even worse, it met the partridges, their stocks have dropped since the 80s, even 90 percent. A total of 80 percent of the field’s bird species are now on the Red list for endangered species.
Without the caterpillars, the birds
starving Yourself in the large cities, so far, actually is the haven of biological diversity, on the verge of a disaster. That leaves at least by the German nature conservation Association Nabu, every spring, organized campaign “hour of garden birds” suspect, in the case of the bird lovers count the Piepmätze in their gardens. Seven of the 15 most common garden bird species this year were so rare as never since the beginning of the action 14 years ago. Particularly species such as Tits that eat only insects or their young to feed, and darted particularly rare through the gardens.
About 3700 species of butterflies there are in this country. Nobody knows exactly, because Germany borders on five major European regions. The moth communities inhabiting very different habitats, from the high altitudes of the Alps to the North German plain. According to divers the communities. But one thing unites them: Everywhere collectors find fewer animals and species. For Reichholf, there is a unifying Element: The butterfly loss goes hand in hand with the expansion of industrial agriculture. Even the smallest scrap of green land is turned into arable land. No wonder, then, finally, the EU subsidizes farmers with direct payments, mainly according to the size of your growing area. The result: Always put the meadows and more wet dry and nutrient-pimped-poor areas with fertilizer.
cities to take insects, the food way
soft corn fields, meadows. “So a uniform landscape, in which only a particularly competitive survival of strong species of plants,” says Reichholf. Grasses and herbs are dependent on very special conditions, to stay on track. And with them the specialized insects. The caterpillars of the swallowtail, for example, snacking on the loved ones of the flowers of the Wild carrot. The Aurora butterfly eat preferably foam herb Meadow. These plants disappear, the Butterflies disappear. Of nature conservation, especially the protection of species, was obviously not able to resist.
Even cities and municipalities take away the insects, the food, complained Reichholf: “as soon As along roads and traffic Islands and the flowers poke their heads out of the ground, municipalities, the areas to mow.” These green spaces get then often again splash of color from tulips, or Crocuses missed, but it helps a little. “The insects of this offer at the most Pollen.”
other measures Also do not show the desired effect, such as an international research project. Unused field margins and fallow land have, therefore, a much greater biodiversity, as promoted by the EU for the protection against Erosion and rewarded the cultivation of grasses or crops.
The farmers themselves, you can’t be accused of this. Farms that do not grow, remain in the cut-throat competition on the track. Reichholf argues, therefore, for fair conditions: “If agriculture is industrially operated, it must be treated like any other industry. That is, it is not for the benefit of more tax and their waste water is properly disposed of.“ Then also, Organic farms had more opportunities to survive.
In his home city of Munich, many organic farmers from the middle of Salzburg Land offer their products. For Reichholf no Surprise: Because Austria is from 1995 to the EU, it preserves a larger agricultural diversity. Here is the Newsletter “” subscribe to the Know

The Association intends to plant less Eco
Currently, the EU support for Agriculture to 2020 – a great opportunity to make a change. On 1. June, the EU Commissioner Phil Hogan presented his plans. Among other things, direct payments to farmers should be linked in the future more than in the past in environmental services.
The German farmers ‘ Association promptly responded: “The first pillar (direct payments) of the Common agricultural policy must be environmentally overloaded.” Farmers ‘ Association, President Joachim Rukwied therefore expected major Changes in the further negotiations. Also Minister Julia Klöckner (CDU) in the template “some practice disabled problems and issues for our farmers”.
So perhaps missed a great opportunity to have the ecological wheel to turn back. Possible the would be quite. Because, according to Reichholf: “insects can reproduce rapidly if the conditions are right.”
