Distribution: : Southern coast of South Africa (Knysna, Keurbooms and Swartvlei Estuaries)

Status: Endangered

    • Collate and synthesise information of major threats to H. capensis (habitat loss and alteration)

    • Collate and synthesis all applicable legislation and review implementation and related conservation success. (in line with Objective 2 of the IUCN Specialist Group).

    • Increase awareness of the conservation status of H. capensis and its related habitats through outreach and media. (High priority)

    • Increase and develop working relationship with conservation authorities to allow for effective knowledge sharing and conservation actions (High priority)

    • Monitor trade of syngnathids in South Africa and check for presence of Hippocampus capensis. (Low priority).

    • Continue to monitor the distribution and abundance of Hippocampus capensis across its range to inform population status and to assist in determining the effectiveness of recovery actions (High priority).

    • Continue the investigation of the ecology of H. capensis within different habitat types, specifically focusing on population size, home-range and growth (High priority).

    • Implement research using eDNA to investigate the range of Hippocampus capensis in estuaries along the South African south coast (High priority).

    • Implement genetics research of H. capensis to investigate population divergence between estuaries and habitats and promote/facilitate future conservation actions based on conservation genomics (Medium priority).

    • Support community and government groups involved in monitoring and recording the presence of Hippocampus capensis and facilitate dissemination of information (Medium priority).

    • Where appropriate, actively encourage community involvement in aspects of Hippocampus capensis recovery including for example, research and monitoring programs (Low priority).

    • Conduct and/or facilitate the mapping and continued monitoring of suitable habitat for H. capensis (High priority).
