The MPA Resilience Self Assessment Tool (R-SAT) helps MPA managers better understand and prepare for emerging threats and change due to external stressors. The tool helps MPAs assess weaknesses and determine priority elements that should be integrated into their resilience-oriented management activities and plans. In situations where relevant data is limited, MPA managers can take a collaborative approach in which they define the data needed to answer the main evaluative questions and work with partners and stakeholders from a range of disciplines and institutions to produce this data. R-SAT is an online tool where users answer multiple choice questions. An Excel spreadsheet is available to record answers before they are transferred online to avoid losing work due to poor quality internet connections. A demonstration version helps new users understand how the tool works. An assessment takes 1-2 hours to complete, and the tool is available in English, French, Spanish, and Portuguese.
