Seagrasses are vital ecosystems that store nearly 20% of global carbon, support fisheries, enhance water quality, and protect shorelines. Yet, they are rapidly declining worldwide due to climate change and human-driven habitat alteration, including nutrient enrichment and physical damage. Along Florida’s Gulf Coast, concern is growing among community members, fishing guides, and land managers about the spread of seagrass damage from boat propeller scars. We introduce SCAR MAPS (Seagrass Conservation through Actionable Research: Management Areas for Prevention of Scarring), a co-production project with one of six objectives is to quantify the ecological impacts of boat scars from 2025–2027. Beginning in April 2025, we combined high-resolution scar mapping with direct field measurements to assess the effects of individual scars, scar density, and their interaction on seagrass function, structure, and bioturbation intensity across multiple spatial scales (e.g., 1 m², 10,000 m²). Our research spans three focal areas (~30 km apart), each differing in seagrass composition and nutrient availability. In each area, we established nine 1-hectare plots across a gradient of scar density per hectare. At each plot, we are measuring water clarity, sediment organics, seagrass and faunal (fish and epi-benthic invertebrate) community structure, and bioturbator disturbance intensity. Here, we present first-year findings on how propeller scars influence seagrass bed structure, fish and invertebrate community composition, and natural disturbance intensity. Locally, results are shared with end-users and inform actions under FLDEP’s 10-year aquatic preserve management plan to prevent and repair propeller scars. More broadly, our study advances applied seagrass ecology by elucidating how meadows respond to propeller scarring under different environmental conditions, improving predictability of scar impacts.
