• WP1: The PAB, comprising national authorities, regional conventions, and international organizations, actively co-created tools and deliverables, shaping the EBM and toolbox needs.
• WP2: New methods for addressing HABs, jellyfish outbreaks, invasive species, and top predator decline were developed and tested at learning sites, contributing to the toolbox.
• WP3: Methods for ecosystem services assessment, tipping points, scenario modeling, and capacity building were applied to case studies and learning sites, including multiple pressure and climate change scenarios.
• WP4: Tikta software version 2.1 was released, featuring Cumulative Effects Assessment (CEA) and Nested Environmental status Assessment Tool (NEAT) modules, with improved functionalities. It is being tested at learning sites.
• WP5: Data management plans were updated, and learning sites prepared scenarios for testing Tikta and other approaches. Methods for monitoring HABs, invasive species, and jellyfish blooms were reviewed and tested, including biologging and molecular strategies for top predators. Tools developed include Pressure2Eco, SCAIRM, Tikta, EasySat Indicators, GES4HABs, MAMBO, CIMPAL+, and SEAS4GES, supporting status and pressure assessments and decision-making.
