Natural lawnmowers

Particularly sustainable and natural lawnmowers have been in use at many places in the city for several years: these are the goats and sheep that spend the whole summer keeping the grass on the meadows in check. On the Bisamberg, around 40 goats help mow the meadows. The animals are ideally suited to caring for drygrass areas, as most of their nutrition comes from leaves and twigs. In this way, the special, very steep landscape is protected against scrub encroachment, and species diversity is restored and maintained. The mowing sheep on Danube Island also help to naturally keep the grasses low every summer. Waldschaf, Zackelschaf, and Steinschaf, Coburger Fuchsschaf, Shropshire and Berrichon du Cher – from mid-May through November, approx. 70 sheep graze the northern end of Danube Island, where they replace mechanized meadow cutting. The herd of sheep comprises various old and rare species. As animal employees, they will spend their summer season over the next three years on Danube Island. In the autumn, they relocate to their winter area.

Nothing to bleat about

That's so true of the goats of the Rautenweg landfill site. The highest elevation in the twenty-second district, Vienna’s largest, is a huge mountain of rubbish. This special hill is located on Rautenweg. Like Mordor for the orcs, this mountain of trash is ground zero for a herd of Pinzgau goats. They are the security detail at the landfill site, where they have been bleating and clambering their way around the tip since 1993. Saving this endangered species, which originates from the province of Salzburg, was a key priority. Today, the fleet-footed mountain goats work as natural lawn mowers to keep all the greenery that springs up at the dump in check. And with more than 100 kids born at Rautenweg, the scheme really is doing its bit to boost the population of these rare animals. “The animals know exactly who we are and run over the minute they see us. Some of the kids were bottle-fed and it looks as though they can still remember. One of them was nicknamed ‘cuddler’,” says waste depot worker Herbert Diesenreiter lovingly of his four-legged helpers.

Between May and October, you can visit the goats and go on a tour of the area:
