Hobson’s Brook Bioblitz took place on the 14th and 15th  June 2024. The Bioblitz was held at Brookside Gardens and New Bit Meadow, Cambridge. New Bit Meadow occupies a position between Hobson’s Conduit and Vicar’s Brook. Brookside Gardens form a narrow strip of greenspace adjacent to Hobson’s Conduit to the north. Experts and volunteers ran hour-long identification sessions and guided walks at the site.  Despite the changeable weather, almost a hundred people participated in the event. The Bioblitz sessions covered plants, small mammals, birds, bats, moths, other insects and freshwater invertebrates.

Brookside Gardens and New Bit Meadow produced 193 different taxa (mostly identified to species level). These included 14 species of birds, 4 mammals, 2 fish, 1 amphibian, 65 types of invertebrates (including 12 moths) and 107 different plant species. Freshwater invertebrates were particularly abundant and diverse in the section of Hobson’s Conduit adjacent to Brookside Gardens and the Botanic Garden.

These results compare well with the 2023 Bioblitz at Darien Meadow and highlight the diversity of habitat present along this part of the Hobson’s Brook corridor.

Bioblitz highlights were the Goldcrest, the Common Blue Damselfly and Water Scorpion, the Serotine Bats, the Green Oak Tortrix Moth, the Pyramidal Orchid, Bee Orchid and Ivy Broomrape.

This Bioblitz has emphasised 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.
