Current population of plants and animals

What effect does the BioDiversum have on the animal and plant species living here? In order to be able to assess this in the future, we had experts record the current flora and fauna on our institute premises in 2019. We have summarized the most important findings here.


(Recording: Wette + Küneke)

  • High proportion of intensive grassland and lawn
  • Green areas close to buildings are partly already planted with flowering bushes
  • Grounds and roadside areas have been intensively managed so far and have high potential for upgrading
  • Some trees are not suitable for the site (Note: Unsuitable spruces were felled in autumn 2019 as the population was massively infested by the bark beetle)

Wild Bees

  • Surprisingly high diversity: 68 species, 18 of which are endangered, for example Eucera longicornis and Andrena labialis
  • 10 species specialized on only one plant family or genus, 5 of them specialized on Fabaceae


Gerd Brunken monitored butterflies and grashoppers.

(Recording: Gerd Brunken)

  • With 21 species very low species diversity, dominant: Maniola jurtina
  • Occurance almost exclusively on the fallow land on the north-east of the premises
  • Conspicuous absence of otherwise common species such as Aglais urticae and certain skippers
  • Most species only represented by a small number of individuals


(Recording: Gerd Brunken)

  • Very few, undemanding species with many individuals
  • Dominant: Chorthippus albomarginatus


Ornithologist Michael Corsmann

(Recording: Michael Corsmann)

  • Rather extensive population (due to surrounding forest): 51 species of which 31 breed on the premises
  • 6 species make up 50 percent of the breeding population: blackcap, blackbird, chaffinch, song thrush, robin
  • 20 percent of breeding birds are cave breeders (and thus dependent on corresponding niches and tree hollows)
  • 14 species endangered (according to Red List Lower Saxony and/or Germany) or on early warning list, including the highly endangered spotted flycatcher and garden warbler
  • The highly endangered species grey-headed woodpecker and peregrine falcon probably breed in the adjacent forest
  • Only few species of the open landscape


Bat expert Jürgen Rommelmann

(Recording: Jürgen Rommelmann)

  • 7 species
  • Dominant are Pipistrellus pipistrellus (most common species countrywide) and Pipistrellus pygmaeus
  • No proof of quarters on the premises
