“…Within the recent occupation by humans of Galápagos in the past 190 years (Andrade et al, 2010; Grenier, 2007; Hennessy & McCleary, 2011; Quiroga, 2009), the archipelago has been transformed, and the human population has proliferated as a direct consequence of tourism and migration (Celata & Sanna, 2012; Grenier, 2007; Hennessy & McCleary, 2011; Ospina, 2001; Walsh et al, 2010; Watkins, 2008). Tourism has increased by 37% from 2009 (163 000 tourists) to 2018 (276 000 tourists) with 180 000 to more than 200 000 tourists annually visiting the islands in the past decade (Galapagos Government Council, 2021; Mazur et al, 2018; UNESCO World Heritage Centre, 2019). Partly to help serve that growing tourism industry, the total human population is increasing in the Galápagos' main populated islands (including Santa Cruz, San Cristóbal, and Isabela; Figure 1), from 25 884 in 2010 to approximately ~33 000 inhabitants in 2020 (i.e., 21.7% increase), with a positive population growth rate averaging 5% per year since the early 1970s (Alava et al, 2014; Galapagos Government Council, 2021; Instituto Nacional de Censos y Estadísticas [INEC], 2022).…”
