“…En este sentido, el resto de las especies detectadas en el transecto (y en la isla en general) no quedan ajenas al peligro de la actividad humana: la Isla Decepción es una de las más visitadas por turistas. Cada año, desde finales de los 90, más de 10.000 turistas desembarcan en la costa interior, principalmente en Whalers Bay, Telefon Bay, Baily Head y Pendulum Cove, alcanzando un peak de más de 25.000 turistas de visita en la isla durante los veranos 2006-2007y 2007(Pertierra et al 2014. Así mismo, las dos estaciones científicas aún operativas en la isla, han mantenido un flujo de investigadores que ha ido en aumento en los últimos años, siendo más de 50 personas las que han hecho presencia en la base Gabriel de Castilla durante la época de verano, para desarrollar actividades de investigación (Pertierra et al 2014).…”

transecto de aproximadamente 2 km entre el Lago Irízar y la pingüinera (Pygoscelis antarcticus) de Punta La Descubierta. Fueron detectados un total de 39 carpetas de vegetación formadas principalmente por briófitos, distribuidas en tres sectores principales, aledaño al Lago Irízar, en Collado Vapor y en Punta La Descubierta. Los briófitos registrados corresponden a 15 especies de musgos y sólo 2 hepáticas, con 11 familias representadas. Se detectó que dos musgos, Sanionia uncinata y Politrychastrum alpinum, con 31 y 9 registros, dominaban las carpetas, con mayor abundancia y frecuencia. Además, se encontró un nuevo registro para la isla del musgo Bryum orbiculatifolium, el cual crece directamente asociado a la pingüinera. Además, se encontró que hay 5 especies de musgos comunes a los tres sectores, aunque otras 5 especies crecen solo en el sector de la pingüinera, diferenciándose esta comunidad de las otras dos. No se detectaron plantas vasculares en todo el sitio de estudio, por lo que se discute la posibilidad de que estos sitios se encuentran en estados de colonización temprana y donde su biota está marcada por la presencia de musgos pioneros que crecen alrededor de las pingüineras, influenciadas probablemente por el aporte de nutrientes del guano depositado.

“…Impacts caused by increasing visitation and the potential establishment of permanent infrastructure (noting that these are not exclusive to tourism) could include: a loss of wilderness and aesthetic values (Summerson and Tin, 2018), increased risk of the introduction of non-indigenous species (Chown et al, 2012), increased risk of pollution events at both small (e.g., dropping of litter) and large scale [e.g., fuel spill from a ship (Aronson et al, 2011)], disturbance of wildlife by humans (Burger and Gochfeld, 2007;Tejedo et al, 2016;Dunn et al, 2019) or aircraft (Hughes et al, 2008), increased atmospheric emissions from vessels, aircrafts and land vehicles (Amelung and Lamers, 2007;Eijgelaar et al, 2010) and increasing cumulative impacts at ice-free locations where scientific, logistic and tourism activities coincide (e.g., Deception Island) (Pertierra et al, 2014).…”

Local Drivers of Change in Southern Ocean Ecosystems: Human Activities and Policy Implications

et al. 2021

View full text Add to dashboard Cite

Local drivers are human activities or processes that occur in specific locations, and cause physical or ecological change at the local or regional scale. Here, we consider marine and land-derived pollution, non-indigenous species, tourism and other human visits, exploitation of marine resources, recovery of marine mammals, and coastal change as a result of ice loss, in terms of their historic and current extent, and their interactions with the Southern Ocean environment. We summarise projected increases or decreases in the influence of local drivers, and projected changes to their geographic range, concluding that the influence of non-indigenous species, fishing, and the recovery of marine mammals are predicted to increase in the future across the Southern Ocean. Local drivers can be managed regionally, and we identify existing governance frameworks as part of the Antarctic Treaty System and other instruments which may be employed to mitigate or limit their impacts on Southern Ocean ecosystems.

“…Deception Island has been identified as critically vulnerable to human impact (Chown et al 2012a, Pertierra et al 2017. In addition to characteristics such as its volcanic activity, unstable terrain and relatively rapid regional climate warming, it has some of the highest numbers of cruise ship visits and tourist landings anywhere in Antarctica (Pertierra et al 2014). The island also has a long history of industrial activity (sealing from early 19th century and whaling until 1931) and scientific activity (with up to four research stations operational during periods between 1944 and the present) (Dibbern 2010, Pertierra et al 2014.…”

Furthermore, there is growing evidence of impacts within some of the ASPA sub-sites as a result of different scientific research activities that conflict with the values for which the sub-sites were designated.…”

Conflicting science requirements impact on rare moss conservation measures

The Antarctic Treaty recognizes the outstanding scientific values of the Antarctic environment through the designation of Antarctic Specially Protected Areas (ASPAs) that have rigorous management plans specific to each site. Deception Island has the largest concentration of rare bryophyte species and communities in Antarctica, while also offering substantial opportunities for research in a range of scientific disciplines due to its volcanic nature. As a result, conflicts between research interests and conservation goals may arise. On the summit ridge of Caliente Hill severe trampling damage to the moss assemblages growing in association with localized geothermal activity was observed. The range of species affected included the entire known population of Schistidium deceptionense, an endemic moss known only from this site, as well as other very rare Antarctic mosses (Ditrichum ditrichoideum, Bryum orbiculatifolium, Bucklandiella subcrispipila, Pohlia wahlenbergii and Dicranella hookeri). A photomapping study was undertaken to characterize further the status of the site and monitor changes within it. Increased awareness, co-ordination of activities and a spatial zoning within the site could help mitigate damage from permitted activities. Nevertheless, prioritization of longer term conservation goals over short-term research interests may ultimately be necessary where local human impact cannot be managed by other means.
