“…Botanical exploration continues adding to our knowledge, including publishing new species, e.g., Eragrostis episcopulus , first recorded in St Helena in 2012 (Lambdon, Darlow, Clubbe, & Cope, 2012), and Nassauvia falklandica in the Falkland Islands (Upson, Clubbe, & Hind, 2013). Species range extensions are regularly recorded, e.g., in the British Virgin Islands (Bárrios, Sustache, Goyder, & Hamilton, 2020; BVI TIPAs National Team, 2019).…”

“…Considering the target upland species investigated here, there have been no previous studies into the ecology of Acaena antarctica or the recently described Nassauvia falklandica [68]. Research on Azorella selago at its sub-Antarctic locations indicates a sensitivity to drought and competition from faster growing species [69] therefore making it at risk from both direct and indirect impacts of climate change.…”

Potential Impacts of Climate Change on Native Plant Distributions in the Falkland Islands

The Falkland Islands are predicted to experience up to 2.2°C rise in mean annual temperature over the coming century, greater than four times the rate over the last century. Our study investigates likely vulnerabilities of a suite of range-restricted species whose distributions are associated with archipelago-wide climatic variation. We used present day climate maps calibrated using local weather data, 2020–2080 climate predictions from regional climate models, non-climate variables derived from a digital terrain model and a comprehensive database on local plant distributions. Weighted mean ensemble models were produced to assess changes in range sizes and overlaps between the current range and protected areas network. Target species included three globally threatened Falkland endemics, Nassauvia falklandica, Nastanthus falklandicus and Plantago moorei; and two nationally threatened species, Acaena antarctica and Blechnum cordatum. Our research demonstrates that temperature increases predicted for the next century have the potential to significantly alter plant distributions across the Falklands. Upland species, in particular, were found to be highly vulnerable to climate change impacts. No known locations of target upland species or the southwestern species Plantago moorei are predicted to remain environmentally suitable in the face of predicted climate change. We identify potential refugia for these species and associated gaps in the current protected areas network. Species currently restricted to the milder western parts of the archipelago are broadly predicted to expand their ranges under warmer temperatures. Our results emphasise the importance of implementing suitable adaptation strategies to offset climate change impacts, particularly site management. There is an urgent need for long-term monitoring and artificial warming experiments; the results of this study will inform the selection of the most suitable locations for these. Results are also helping inform management recommendations for the Falkland Islands Government who seek to better conserve their biodiversity and meet commitments to multi-lateral environmental agreements.

“…The species of Nassauvia commonly inhabit the arid extra-Andean semidesert and the Andean highlands. The information on the distribution of specimens of Nassauvia is based on the literature (Cabrera 1971(Cabrera , 1982Kalin Arroyo and Marticorena 1988;Upson et al 2013;Katinas 2015), on the investigation of herbarium materials, and on databases. Our team has conducted fieldwork for decades in the natural habitats of the genus, and besides this we have revised and compiled a large database for Nassauvia.…”

“…Global threat category of the 39 Nassauvia species have been assessed according to the IUCN criterion B, thus we provide the first IUCN category of risk for 36 species. As far as we know, only the three Malvinian/ Falklandian taxa had been previously evaluated against the IUCN scheme: N. gaudichaudii and N. serpens were included with a LC (Least Concern) category in the IUCN Red List (http://www.iucnredlist.org; February 1, 2016), and N. falklandica was categorized as CR (Critically Endangered) in its description (Upson et al 2013). Our assessment using current and projected scenarios (for both AOO and EOO) for the first two taxa gave rise to VU (Vulnerable) and EN (Endangered) risk categories, respectively.…”

The elaboration of a comprehensive database about the distribution of the South American genus Nassauvia has allowed investigate its conservation biogeography. The combined use of historical (Dispersal Vicariance Analysis) and ecological (UPGMA) biogeographical approaches has led to detecting past, present and future critical areas in the evolution and persistence of the genus. According to the size of distribution areas, number of locations, environmental niche models, and predicted shifts of these spatial characteristics following the Intergovernmental Panel on Climate Change forecasts for the next decade, it has been possible to award the level of global and national risk for all species of the genus and assign their corresponding IUCN categories. Severe gaps in legal and in situ conservation policies have been detected within the region, making it urgent the adoption of measures aimed at preventing the extinction of the most endangered species. We identify a future dramatic loss of Nassauvia species in the Andes and conversely a species increase in Patagonia. Patagonia has emerged as the cradle of the genus and could be its refuge in the future according the predictions targeted by climate change. Communicated by Daniel Sanchez Mata.
