OBGA works with local conservation groups including The Freshwater Habitats Trust (FHT) who run the ‘Saving Oxford’s Wetland Wildlife Project’. OBGA is currently propagating plant species for the FHT for its ‘Species Conservation Hub’ at Boundary Brook Nature Park, for example Sium latifolium, a plant once typical of wet, species-rich, tall-herb fens in the UK, now much declined. Our horticulturalists have successfully provided FHT with Sium latifolium plants for new ponds created in Oxfordshire. We also propagate other rare aquatic species including frogbit bareroot Hydrocharis morsus-ranae, and bladderwort Utricularia australis. We are also collaborating with Christ Church and TVWMRP to develop a restoration programme for Christ Church Meadow as part of the Thames Valley Wildflower Meadow Restoration Project.
