Ecological responses to cumulative effects
This project brings together mātauranga Māori and western science to develop new knowledge about cumulative effects

This project addresses the cumulative effects of multiple stressors on soft-sediment and rocky reef biodiversity and ecosystem function. This knowledge is necessary to underpin models, decision-making processes and to implement EBM.
- Co-develop place-based tohu (traditional indicators) of the ecological condition of our estuaries and coasts
- Develop ecological footprint analysis to support improved decision-making, investment and knowledge of how activities and stressors impact on biodiversity and ecosystem services
- Investigate bottlenecks to recovery of reef and soft-sediment seafloor ecosystems
- Develop new methods to map ecological response footprints of stressors and their impacts on ecosystem services
- Provide a cumulative effects assessment framework that is based on understanding of interactions between ecosystem components to inform marine spatial planning and risk assessment
- Identify the constraints on ecosystem recovery to better manage risk and expectations.
We will engage in field studies, develop models and work with broader environmental initiatives across Aotearoa New Zealand proposed by iwi, community groups, central or regional government that support EBM developments. This includes:
- Hauraki Gulf Seas Change process
- Tauranga Harbour and Ōhiwa Harbour in response to actions to improve biodiversity and ecosystem function
- Marlborough Sounds with multi-sector interests in trailing EBM
- Southland estuaries with interests in enhancing the removal of nitrogen from the coastal ecosystem
In the context of each of these initiatives, we will work ecological communities and processes that play important roles in ecosystem service delivery and resilience.
For example, in Ōhiwa Harbour we will work with the potential for shellfish populations to enhance the ecosystem recovery of estuaries and rehabilitate negative effects of sediments and nutrients.
This research will allow us to develop frameworks across the Challenge that improve the way we make decisions about the risks posed by different activities in the marine environment, and the opportunities we have to improve the ecological health and mauri of our coasts and estuaries.
