Wetlands

We offer a wide range of wetland-related skills ranging from desktop mapping and catchment-based wetland studies through to detailed wetland delineation and site-based PES and functional assessments. We also have excellent experience in wetland rehabilitation planning and can assist in designing efficient wetland offsets in line with best-practice.  Given our active involvement in developing best-practice guidelines, we are able to apply best available science in the work we undertake.
