Fulbourn Fen Nature reserve

I am quite excited by Fulbourn Fen , it was my first time there today I found a large aggregation of Ivy Mining bees , over thirty hornets. I am looking forward to seeing what solitary bees emerge in the spring and summer amongst other insects.

Its good to see so many fallen trees just left where they fall.

Fulbourn Fen is a SSSI

The site holds species-rich neutral grassland on calcareous loam and peat, together with remnants of ‘fen’woodland. These habitats are now rare in lowland England where only small fragments are known topersist. Areas of secondary woodland have also developed on the drier areas and contribute to the overall habitat variety of the site and its value to bird and invertebrate life.
The calcareous loam pastures are dominated by a range of herbs and grasses. Of the grasses, Yorkshire fog Holcus lanatus and red fescue Festuca rubra are particularly common along with herbs such ascowslip Primula veris, salad burnet Sanguisorba minor and purging flax Linum catharticum. Thewetter areas support tall fen vegetation including species such as marsh-orchids Dactylorhiza spp., fen
bedstraw Galium uliginosum, meadowsweet Filipendula ulmaria and fleabane Pulicaria dysenterica.
The ‘fen’ woodland areas have been rather modified by planting but are retained with the site boundary for the natural elements which still remain and for their ornithological and entomological value in association with the other areas. Wych elm Ulmus glabra, alder Alnus glutinosa, oak Quercus robur and ash Fraxinus excelsior occur as characteristic components of ‘fen’ woodland. The ground flora
includes stinking iris Iris foetidissima, stinking hellebore Helleborus foetidus and wood sanicle Sanicula
europaea.
