Identifying spatial conservation priorities using Traditional and Local Ecological Knowledge of iconic marine species and ecosystem threats

Abstract

Marine Protected Areas (MPAs) can be an effective spatial approach to conservation, especially when they involve genuine consultation that considers the diversity of stakeholders. Participatory mapping and semi-structured interviews were conducted with 52 stakeholders and 22 managers and scientists to identify ecological priorities and concerns across a large temperate MPA in Port Stephens-Great Lakes Marine Park, Australia. There were 19 iconic species of fish, dolphins, whales, and sea turtles that were the focus of ecological priorities and stakeholder interactions with the marine environment. Effectiveness of the current MPA management plan for addressing stakeholder priority and concerns, was assessed using GIS spatial modelling that created fuzzy-set species distribution models (SDMs) based on Traditional and Local Ecological Knowledge as well as scientific and citizen-science survey data. These spatial models for the iconic species across the MPA were then overlaid with ecological concerns of the stakeholders to create a spatial understanding of local threats, and priority areas for targeted management. Poor water quality from terrestrial primary sources was the main concern of stakeholders, more so than in-water threats such as poor fishing practices or impacts to iconic species. While local managers and scientists were relatively reluctant to answer interview questions, there was a general misalignment in approaches to iconic species management, especially for mobile and migratory species, and misunderstanding of stakeholder perceptions of threats. Participatory mapping of social-ecological values provides a method for stakeholders and decision-makers to better understand, discuss, and adapt marine spatial management approaches that support a diversity of conservation and management priorities.
