The ALRV already launched its “Garden Eden” project in 1999. New plants being planted on the grounds guarantee the continual beautification of the traditional site at the Soers. For a donation trees could and still can be sponsored at the CHIO grounds. In the meantime, there are around 400 trees (particularly lime trees) and 4.6 kilometres of hedges with around 30,000 plants across the grounds. Rainwater is collected in a biotope next to the Deutsche Bank Stadium.
