Dudman Limited specialise in sand extraction and quarry restoration through the importation of inert materials. The Ecology Co-op assisted them with a project at Rock Common Quarry in West Sussex - a 33.5ha site that has been in operation since the 1920s and subject to several planning permissions since the 1950s.

As an independent charity that manages a portfolio of royal palaces, HRPs Sustainability Action Plan sets an ambitious target: to achieve nature-positive carbon net zero by 2050, adapting its gardens and parks to be more resilient to the effects of climate change. To work towards this, the charity needed robust and measurable ecological baselines established across four of its iconic sites.
