We’d originally considered making a sand martin habitat but the construction and maintenance involved have put us off. However, the environmental architect has proposed the idea about a ‘sand bank’ involve building up a ‘layer cake’ of sandy soil with layers of cement or lime mortar mixed between to create a low ‘cliff’. There would be some basic ‘building’ work involved in that a digger would be needed and using shuttering to allow the layers to set. This would potentially serve as habitat for bees, wasps and other invertebrates and not need the annual maintenance of the sand martin bank.
Have we any potential volunteers from businesses in the building, construction or associated trades? A project for a team of apprentices, perhaps?
The investment in this bank would be in the future of the planet’s pollinators and other wildlife.
