Sea-Level Rise Modeling as a Catalyst for Effective Coastal Management in West Hawai’i
Project Status: This project began in September 2016 and is projected to be completed in August 2019
In collaboration with The Nature Conservancy and the Hawaii Sentinel Site Cooperative, we are evaluating the effects of sea level rise of unique coastal habitats on the west coast of Hawai’i. Predictions of sea level rise impacts will guide updates to habitat management plans for the regions.
The west coast of Hawai’i supports groundwater-fed anchialine pools (landlocked bodies of water with a subterranean connection to the ocean), wetlands, and fishponds that occur throughout the west Hawai‘i and support numerous endangered and endemic species as well as provide key ecosystem services to natural and human communities. Predicting the effect of sea-level rise (SLR) on these ecosystems requires models that incorporate groundwater levels which are elevated above sea levels and will exacerbate flooding in the porous basalt aquifer.
What We Are Doing:
This project will improve management effectiveness of coastal areas based on the predicted
response of wetland, fishpond, and anchialine ecosystems to rising sea levels in the west Hawai‘i
area. To accomplish this, we will refine existing water level models with high resolution groundwater data and use the improved models. These improved models will then be used to assess the potential ecological impacts of changes in sea level on high priority groundwater-fed wetlands, fishponds, and anchialine pools and how will these impacts will affect the ecosystem services along the coast. Based the results of these assessments, the project will determine what priority management and policy actions can be implemented to reduce the vulnerability of these coastal habitats and communities.
To maximize stakeholder engagement and application of project results, the project team will coordinate a series of workshops to evaluate and update the South Kohala Conservation Action Plan High resolution data on SLR. In addition, results of project analyses will be incorporated into geospatial products including maps and the online decision support tool - Coastal Resilience (www.maps.coastalresilience.org), to aid conservation planning and management actions for ecological targets effects on local habitats and processes will be a key part of this effort.
The project is led by The Nature Conservancy and is part of the NCCOS Ecological Effects of Sea Level Rise Program.
