  abstract = {{S}ustainable coastal social-ecological systems rely on healthy ecosystems known to provide benefits to both nature and people. {A} key ecosystem found globally is seagrass, for which maps at a scale relevant to inform conservation and management efforts are often missing. {E}elgrass ({Z}ostera marina), a species of seagrass found throughout the northern hemisphere, has been declining in {P}lacentia {B}ay, an ecologically and biologically significant area of {C}anada's east coast subject to an increasing human impact. {T}his research provides baseline information on the distribution of eelgrass meadows and their anthropogenic stressors at seven sites of {P}lacentia {B}ay and three sites of the adjacent {T}rinity {B}ay, on the island of {N}ewfoundland. {H}igh-resolution maps of eelgrass meadows were created by combining ground-truth underwater videos with unmanned aerial vehicle imagery classified with an object-based image analysis approach. {V}isual analyses of the imagery and underwater videos were conducted to characterize sites based on the presence of physical disturbances and the semi-quantitative cover of epiphytes, an indication of nutrient enrichment. {A} total eelgrass area of similar to 1 km(2) was mapped across the 10 sites, with an overall map accuracy of over 80% for 8 of the 10 sites. {R}esults indicated minimum pressures of physical disturbance and eutrophication affecting eelgrass in the region, likely due to the small population size of the communities near the eelgrass meadows. {T}hese baseline data will promote the sustainability of potential future coastal development in the region by facilitating the future monitoring and conservation of eelgrass ecosystems.},
