Restoration is a key component of global and national efforts to combat ecosystem degradation, reduce biodiversity loss, and adapt to climate change, and there is currently an impetus to scale up restoration efforts. However, our ability to track progress toward restoration targets is limited by the lack of consistent and standardized data on objectives, interventions, and outcomes. To address this, a collaboration of conservation practitioners and scientists from around the world have developed the Mangrove Restoration Tracker Tool (MRTT), an application to record and track outcomes from mangrove restoration projects. The MRTT records information across the lifetime of a project, capturing data describing the site background and pre-restoration baseline and the restoration interventions and costs, as well as post-restoration monitoring that incorporates both socioeconomic and ecological factors. The MRTT allows decision makers, practitioners, and site managers to access information that is essential in making informed, evidence-based decisions on restoration interventions to maximize impact and success.
