Larger box with two curved internal voids narrowing down to tight crevices at the top. Suitable for a range of bat species, mating roosts and spring and autumn roosts where the thermal mass is a benefit. Similar to Kent type bu with a rot hole entrance and more natural appearance. Top loop for more comfortable carrying and quick initial attachment to the tree and two through the box nail holes for secure attachment.
Bark Boxes are constructed using an incredibly tough felt made of recycled polyamide combined with a cement and recycled cellulose fibre mix. The felt makes the construction of curves and more natural forms easy, the cellulose fibre will allow the outer layers to mellow and support lichens and mosses in time.
