Flowering meadows for endangered butterflies

When was the last time you saw a shimmering yellow Golden Eight flying over the meadows? Or a shimmering bluish Purple Emperor butterfly? The number of butterflies has declined massively over the last 30 years - studies estimate a decline of up to 75% (Hallmann et al., 2017). This is already having an enormous impact on bird life, as many birds such as swallows and swifts live on insects. For a large number of small birds, insects are particularly important during the rearing phase. Our own food supply is also dependent on the help of insects: of the 107 most commonly grown crops worldwide, 91 are pollinated to varying degrees. Strawberries, cherries and rapeseed produce particularly rich yields when pollinated by wild bees or other insects.

Flowering meadows for endangered butterflies
need
Meadows rich in flowers and herbs to protect endangered butterflies and other insects.
activity
The NABU Foundation buys meadows at Windknollen and guarantees the grazing by a local shepherd necessary for the preservation of the meadows.
Measurable performance
Number of square meters of meadow that are permanently purchased and placed under nature protection.
Result
Grazing by the shepherd can continue and the biodiversity at Windknollen is actively protected.
Systemically relevant impact
The protection of the wind turbine is guaranteed in the long term and biodiversity is protected.
background

The main cause of the loss of insect species such as butterflies and bees is the constant intensification of agriculture with high use of pesticides, overfertilization, draining of wet meadows and the conversion of grassland to arable land. Even in nature reserves, conventional agriculture is generally permitted, with all the problems of pesticide use and overfertilization. There is often also a lack of proper care to preserve the biodiversity of flora and fauna in the long term. Without grazing, species-rich meadows become overgrown with bushes - sensitive plants and numerous insects retreat in favor of a few species.

This is precisely the danger that threatens the Thuringian nature reserve “Windknollen”. A very high level of biodiversity has been preserved here because no pesticides or artificial fertilizers have been used to date. Instead, a flock of sheep regularly grazed the wide, species-rich semi-arid grasslands, over which butterflies such as the Golden Eight, Large and Small Purple Emperor and the Blue Butterfly fluttered. Now 195 hectares of this nature reserve are up for sale from the previous owner, the Thuringian State Development Company. If a new owner were to terminate the collaboration with the shepherd, this would mean the end of the immense biodiversity and the meadows would become overgrown within a few years.

The good deed

In order to preserve the special biodiversity at the "Windknollen", grazing must continue. In order to guarantee this in the long term, the NABU National Natural Heritage Foundation has negotiated the purchase of the 195 hectares at the Windknollen with the previous owner, the Thuringian State Development Company. The NABU National Natural Heritage Foundation will buy this natural paradise by 2021. Today's good deed will help to buy parts of the area and place them under nature conservation. As the owner, the foundation can secure grazing by the traditional shepherd in the long term and thus preserve the special biodiversity at the Windknollen. This will protect another area in which numerous endangered species live.

Human Development Index (Human Development Index)

Germany is very densely populated. Many areas are used for agriculture. Studies show that even in German nature reserves, insect diversity has declined by 76% since 1990 (Hallmann et al., 2017).
