This year the Trustees of Hobson’s Conduit thank St Mary’s School for their kind permission to base our sixth annual Bioblitz in their Brookside garden.

In 2023 our Hobson’s Brook Bioblitz was held at Emmanuel College’s Darien Meadow, Long Road, Cambridge. Darien Meadow lies between Hobson’s Brook and the railway.

A dozen experts and volunteers ran hour-long identification sessions and guided walks at the site. The Bioblitz sessions covered plants, small mammals, birds, bats, moths, other insects and freshwater invertebrates.

180 different taxa were found (mostly identified to species level). These included:

  • 28 species of birds
  • 6 mammals
  • 3 fish
  • 1 amphibian
  • 85 types of invertebrates (including 17 moths), and
  • 57 different plant species.

 

Bioblitz highlights were the Blackcap, Buzzard and Kestrel, the Common Blue Damselfly and Speckled Wood Butterfly, the Soprano Pipistrelle Bat, the Bank Vole, the Small Grass Shieldbug, and theGlaucous Sedge.

These results are comparable with previous Bioblitzes: 2022 at Clare College’s North Paddock, 2019 at Clare Sports Ground, 2018 at Hobson’s Park, Trumpington and 2017 at Nine Wells and Empty Common.

Together they capture the diversity of habitats along the Hobson’s Brook Corridor.This year we will focus on the Brookside gardens, the Conduit along the Botanic Garden frontage, New Bit and Vicar’s Brook.

On Friday early evening and on Saturday morning Trustees will conduct guided walks along Hobson’s Brook and Conduit.

Our programme of Bioblitz events has highlighted the biodiversity of green spaces close to the built environment, and shows the importance of the Hobson’s Brook ‘green corridor’ in preserving wildlife in the City of Cambridge. Maintaining a strong flow of high quality water in Hobson’s Brook is clearly essential for the continued success of these ecosystems, which offer considerable benefits to the people that live close by.

The Hobson’s Brook corridor forms part of the Cambridge Nature Network.
