MacKinnon spent a decade working in the field on tropical ecology in Indonesia and became recognised for her knowledge and expertise. Her focus developed into the planning and management of protecting areas because of their conservation value, and she worked for another 20 years on other conservation projects around the world taking leadership roles to apply knowledge to conservation of biodiversity, natural resources and the issues of local communities living in these regions.^[3] She was a member of several national and international committees and organisations working on nature conservation. She was the lead biodiversity specialist at the World Bank for 16 years (1994–2010), and led the consideration of conservation within all development programmes.^[4] She was a member of the leadership of Wetlands International from 2011 until 2021 and encouraged the organisation's involvement in the conservation of peatlands.^[5] She was the deputy chair of the IUCN World Commission on Protected Areas followed by two terms as Chair (2015 until 2021), having been involved with the organisation since 2010.^[2][3] MacKinnon co-chaired the IUCN WCPA Specialist Group on Other Effective Area-based Conservation Measures with Harry Jonas from 2016 to 2023, which included securing a decision by Parties to the Convention on Biological Diversity that sets out a definition and criteria for identifying OECMs.^[6]
