They are back: Sheep and goats graze the Wannsee campus again

The meadows are lush green, the ice saints (almost) over: Now is the perfect time for the sheep and goats to return from their winter quarters! Until late autumn, they will now graze the near-natural HZB campus in Wannsee and serve the natural preservation of the landscape - completely without a lawn mower.

The meadows are lush green, the ice saints (almost) over: Now is the perfect time for the sheep and goats to return from their winter quarters! Until late autumn, they will now graze the near-natural HZB campus in Wannsee and serve the natural preservation of the landscape - completely without a lawn mower.

On 14 May 2020, shepherd Olaf Kolecki brought his "protégé" back to the Wannsee campus. Among them are five sheep (4 white Skudden and one black Skudden-Pomeranian Landschaf crossbreed, five lambs (3 white Skudden lambs and 2 black lambs, mother is the crossbreed) and five goats (2 Boer goats, the brown and the brown-white and three goat lambs).

Since goats and sheep have different food preferences, this mixture is just right for maintaining the green areas. The grazing is particularly insect-friendly and contributes to increasing the biodiversity of the wild meadows. And also many employees have grown fond of the animals over the past year and have missed the bleating on the campus a little bit in the last weeks.

In an interview (GER) last year the shepherd answered many questions about his work.

Before the arrival of the sheep and goats, the fenced-in eastern area in Wannsee was still being cleaned up. At the beginning of the year the old meadow orchard was "revived". For this purpose, sheds were torn down and some trees were felled to give the old fruit trees more light again. The wood of the felled trees was piled up in several deadwood heaps. This has created an important habitat and refuge for insects and small animals.

Sustainability at HZB on the Intranet

The HZB is intensively engaged in sustainable action and research. An overview of the topics and measures can be found on the newly designed intranet pages on sustainability (GER).

    Nanodiamonds can be activated as photocatalysts with sunlight
    Nanodiamond materials have potential as low-cost photocatalysts. But until now, such carbon nanoparticles required high-energy UV light to become active. The DIACAT consortium has therefore produced and analysed variations of nanodiamond materials. The work shows: If the surface of the nanoparticles is occupied by sufficient hydrogen atoms, even the weaker energy of blue sunlight is sufficient for excitation. Future photocatalysts based on nanodiamonds might be able to convert CO2 or N2 into hydrocarbons or ammonia with sunlight.
