Vergroten van Biodiversiteit op de Campus
Kijk regelmatig op deze pagina voor meer informatie over het vergroten van de biodiversiteit aan de Universiteit Leiden.
Leiden heeft een van de meest versteende binnensteden van Nederland. Dit is niet bevorderlijk voor de biodiversiteitscrisis en de Universiteit Leiden, met een flink aantal gebouwen binnen de Singels. De prioriteit moet zijn om een positieve impact op de zaak te hebben.
Momenteel onderneemt LUGO samen met interne afdelingen en Hortus Botanicus stappen om de gebouwen en de omgeving een positieve invloed te laten hebben op de biodiversiteit. En, we beginnen vandaag bij de oude Universiteitsbibliotheek! Annetje Ottow, voorzitter van het College van Bestuur, heeft zojuist de eerste planten geplant voor het LUGO-biodiversiteitsproject aan de Universiteit Leiden!
Voor meer informatie over de uitkomst en toekomstige projecten, volg de Leiden University Green Office, schrijf je in voor de maandelijkse LUGO nieuwsbrief of neem een kijkje op de LUGO website.
Expertise
Leiden University has the in-house expertise and the connections to develop innovative plans and project which will have an positive impact on the local biodiversity. Together with the Hortus Botanicus and Naturalis we examined the bee species which were spotted at the Hortus as shown in the list below.
List of bees (in Dutch):
- Grasbij, Andrena flavipes
- Tweekleurige zandbij, Andrena bicolor
- Vosje, Andrena fulva
- Roodzwarte dubbeltand, Nomada fabriciana (nestparasiet van o.a. Andrena bicolor)
- Langkopsmaragdgroefbij, Lasioglossum morio
- Aardhommel-groep, Bombus terrestris/lucorum/magnus/cryptarum
- Steenhommel, Bombus lapidarius
- Akkerhommel, Bombus pascuorum
- Weidehommel, Bombus pratorum
- Gehoornde metselbij, Osmia cornuta
- Rosse metselbij, Osmia bicornis
- Gewone sachembij, Anthophora plumipes
- Tuinhommel, Bombus hortorum
- Vierkleurige koekoekshommel, Bombus sylvestris
- Viltvlekzandbij, Andrena nitida
- Grijze rimpelrug, Andrena tibialis
- Wormkruidbij, Colletes daviesanus
- Klimopbij, Colletes hederae
- Roodpotige groefbij, Halictus rubicundus
- Grote wolbij, Anthidium manicatum
- Grote klokjesbij, Chelostoma rapunculi
- Grote bladsnijder, Megachil
Opening of Biodiversity Project at Old University Library
Since the desire to support these species and enable to travel further grew, we wanted to create more biodiversity hotspots around University buildings. These hotspots needed to have special vegetation which these specific types of bees can thrive on. For that reason, the vegetation was to be selected based on the properties desirable for these types of bees.
Locations
Oude UB, Rapenburg 70
- Before, the symbolic and iconic entrance garden used to be a grass lawn not enabling insects and animals to nestle and make it their home. The garden was totally renovated using the plant sorts provided by Hortus, it now consists of 4 sections where plants can grow freely separated by pathways for people to take a closer look at the amazing vegetation. The sign is there to inform people walking by about the project as well as motivate them to do something themselves.
Gravensteen
- The back garden, where the bikes are stored, used to consist only of stone without any vegetation. For that reason, a small strip of green was made. In collaboration with local staff members working at Gravensteen, the garden is maintained offering them fresh herbs for tea.
Kamerlingh Onnes Gebouw
- The Kamerlingh Onnes Building already has a green roof where vegetation can grow freely, however at the ground level there is little green beneficial for the biodiversity. In collaboration with the municipality, we created 2 strips at the west- and east-side of the building where vegetation can grow freely. This project is still in progress and the plants will be put in the ground somewhere next spring.
Other Initiatives
- The Leiden Bio Science Park is heavily focussing on building with biodiversity in mind. The park itself, but also the relatively new buildings are required to live up to nature inclusive building standards with the aim to make as little impact possible to the established biodiversity.
- ‘Stoepplantjes’ is an interactive project from the Hortus, anyone can help! It is a project aimed to create more awareness of the beautiful and important little plants growing between tiles and rocks in Leiden. These wild plants may be considered weeds, or make it look untidy. However, these plants are really important for the rainwater drainage as well as the biodiversity. Want to help? Simply get your chalk and name the type of plant and share it on social media! Check out their website for more information.
