An Australian designer develops hempcrete tiles to recreate tree hollows and rocky crevices; shelters aim to help threatened wildlife, including eastern quolls and ringtail possums

• Australian designer Xavier Earls has developed Bush Cradle, a modular wildlife habitat system made from hempcrete tiles that mimic natural shelters such as tree hollows, fallen logs and rocky crevices.
• The system is designed to help conservationists create customised refuges for native animals facing habitat loss.
• Its four interlocking tile designs can be assembled into different configurations, including tree hollows and ground dens, with entrances tailored to individual species.
