“…Occasionally, the management authority also monitors the spatial distribution of species, density, coverage, species richness, and community structure (Markov and ECOSS Partnership, 2019). Data on the status and distribution of P. marinus, A. fallax, and seagrasses are deficient, while much more information is available for the identified target seabirds (Ente Regionale Parco Delta del Po Veneto, 2010; Verza et al, 2011;Bon et al, 2013;Scarton et al, 2013;Verza, 2015;Scarton et al, 2018;Valle and Scarton, 2018;Miocǐc-Stosǐcé t al., 2020;Scarton and Valle, 2020;Valle and Verza, 2020;Scarton, 2022). However, regular monitoring, necessary to detect population trends of these species and guide the adoption of adequate measure, is still lacking (Markov and ECOSS Partnership, 2019;Golec and ECOSS Partnership, 2020).…”
