Biography 

The focus of Donovan’s professional work over the last 23 years has been on wetland ecology and management. He has gained much experience in a great variety of wetlands under many different land-uses, mainly in South Africa, as well as across eastern and southern Africa, and collaborates with many different government and non-government organizations.   He has worked extensively on the assessment of wetland ecosystem services and ecological integrity for a variety of purposes, including ecosystem rehabilitation and sustainability assessments, as well in the development of several wetland assessment methods.

Qualifications

 PhD

Current Research Projects

  • The development of a model for identifying trade-offs between wastewater and solid waste inputs to a wetland and the multiple ecosystem services supplied by wetlands.
  • To provide technical expertise as the wetland specialist in a multi-disciplinary team conducting a resource economic evaluation of wetlands and their rehabilitation in the upper Breede River catchment.

Recently Completed Projects (2020-23)

  • An assessment of organic soils in five wetlands in the Langeberg Mountains, Herbertsdale: extent, degradation, threats and recommendations.
  • An evaluation of the ecological outcomes at Working for Wetland rehabilitation sites across all of South Africa’s provinces.

Hobbies and Interests

Growing food in the garden, escaping to the mountains frequently, and taking on invasive alien trees for a full body workout.
