Hawke's Bay regional study

This collaboration in Hawke's Bay is mapping environmental stressors, their interactions, and providing guidance for reducing their impacts.

We are working with stakeholders and iwi partners in Hawke's Bay to take a holistic approach to local marine management. Our focus is on implementing ecosystem-based management (EBM) in a real-world example by combining science and mātauranga Māori with the tools and resources from our previous research.

Stage 1 of this project is now complete. Stage 2 is now underway.

Based on scenarios identified by HBMaC, we are now working to adapt EBM tools to identify and prioritise potential management or policy options, and/or fill gaps in both scientific and mātauranga knowledge identified by the conceptual systems map of the two marine stressors.

About stage 1

In collaboration with HBMaC, stakeholders and iwi, we mapped two environmental stressors in the Hawke's Bay marine environment: freshwater sedimentation and loss of benthic (seabed) structure, and their interactions. These are presented in systems maps. We also compiled a list of metadata for existing environmental and socio-cultural datasets that could be used populate model scenarios based on the systems map. The systems maps, summary and webinar recording are available below.

Why Hawke's Bay?

Hawke’s Bay has a diverse coastal marine ecosystem with sandy beaches, inter-tidal reefs, dunes and estuaries. The region has large river systems, fisheries, productive lands and ocean outfalls which can add stress to the marine system and impact on people’s values for the coastal area.

What are marine stressors?

Marine stressors include contaminants or sediment from the land, climate change, habitat loss and fisheries activities. 

Who are HBMaC?

Hawke's Bay Marine and Coastal Group (HBMaC) is a multi-stakeholder group that includes recreational and commercial fishers, tangata whenua and government agencies, and is chaired by Hawke’s Bay Regional Council science staff.
