Citizen Science in El Chalten

At the northern tip of Glaciers National Park in Argentine Patagonia, the small town of El Chalten is situated in an amazing and iconic landscape. However, in spite of being flanked by the Fitzroy Mountains and just over these incredible Andean peaks the icy expanse of the Southern Icefields, El Chalten is not removed from global ecological programs. In the past few years, residents and park rangers have reported sightings of the introduced invasive species – the American mink (Neovison vison).


For this reason, the Argentine National Parks Administration’s Southern Patagonia Coordination Office has initiated a citizen science monitoring program to involve the local community in the detection of this species, to help managers determine quick and appropriate action. Managers, park rangers and scientists have created an education and involvement campaign that will last until February to create greater consciousness of the issue and also establish formal mechanisms for citizens to report their findings.

Chilean-Argentine Collaboration via Internships

Gabriel ZegersIn the spirit of crossing boundaries (geographic, political and academic), the ECO-Link project being developed in Tierra del Fuego with the support of the U.S. National Science Foundation has sought to bring together collaborators from Chile, Argentina and the U.S. to study the social and ecological dimensions of invasive species management and ecosystem restoration. These team members include government agencies, such as the Argentine National Parks Service and the Chilean Agriculture and Livestock Service, but also academic programs, such as Virginia Tech University and the National University of Tierra del Fuego. Beginning in December 2012, this group has expanded to include a nascient collaboration with the Catholic University in Santiago. From mid-December to mid-January, Gabriel Zegers (student of Agronomy with a mention in Environmental Management) conducted an internship at the Austral Center for Scientific Research in Ushuaia. Under the aegis of ECO-Link, Gabriel carried out a preliminary analysis of the political and institutional dimensions of Chilean incentives, laws and regulations surrounding invasive species and ecosystem conservation.

Long-Term Bird Research in Tierra del Fuego

For the past 3 years, researchers at the Austral Center for Scientific Research have led an initiative to establish long-term avian research in Tierra del Fuego Island. With the support of Birder’s Exchange, these scientists are working with the staff of Tierra del Fuego National Park and local tourism operators to link the ecological research with other social actors and bring greater awareness and involvement of the citizens of Ushuaia to the forest birds that surround the world’s southernmost city. To date, this project has helped to establish seasonal patterns of forest avifauna and also determined specific vegetation and habitat conditions required for particular species. The goal of this program is not only to involved different social actors in the research being conducted in the national park, but also bring tools that decision makers can use in the future to improve the design of protected areas, specifically bringing a landscape level focus to the study of biota and habitat in southern Patagonia.

NatGeo Awards Grant to Study Riparian Forest Restoration in Tierra del Fuego

The National Geographic Society recently awarded a Young Explorer Grant to Jon Henn, who together with Drs. Guillermo Martínez Pastur, Vanessa Lencinas and Christopher Anderson, prepared the project to study the methods needed to restore riparian Nothofagus forests in Tierra del Fuego after the removal of invasive beavers. Mr. Henn will work with researchers in Tierra del Fuego for a year with the support of a Fulbright Scholarship, as well. During that time, this team seeks to determine key information regarding the ecophysiology and regenerative capacity of Nothofagus trees in beaver meadows. In this context, the research will also be linked with other ongoing studies funded by the U.S. National Science Foundation to better understand and manage invasive species and ecosystem services in southern Patagonia (see below).

NSF Supports Social-Ecological Research Project in Tierra del Fuego

The US National Science Foundation recently awarded a major grant to Virginia Tech University, Advanced Conservation Strategies and OSARA to conduct a social-ecological research project in Tierra del Fuego during the coming two years. The project, entitled Ecology, Culture & Outcomes: Linking Human Perceptions & Socio-Ecological Thresholds for Ecosystem Restoration (ECO-Link) brings together US researchers with Argentine and Chilean colleagues from academic, NGO, and governmental institutions to determine whether a current lack of participation in ecosystem management initiatives by landowners is influenced by a broken incentive structure that does not account for feedbacks between underlying social perceptions and ecosystem service delivery. Studying efforts to control invasive beavers and subsequently reforest riparian zones on Tierra del Fuego Island, we hypothesize that the thresholds that separate inaction from action in conservation can be overcome by explicitly integrating social and ecological understanding into the design of effective incentives. The link is currently seeking to hire a postdoctoral fellow and a master’s student. More information on MS position can be obtained by contacting Co-PI Dr. Michael Sorice. For notification when the postdoctoral advertisement is posted, contact PI Dr. Christopher Anderson, the project’s lead investigator.

Patagonian Integration

From 6-10 August, the Argentine National Patagonia Center (CENPAT for its acronym in Spanish) hosted the 3rd “Young Patagonia Conservation Leaders” Meeting in Puerto Madryn. Participants came from throughout Patagonia and were invited specifically based on their efforts in marine conservation. Workshops held during the week-long event focused on leadership development with specific courses on interpersonal communication and project design and evaluation. An outgrown of these training initiatives, led by Dr. Alexandra Sapoznikow, is the creation of a new Patagonia-wide emerging leaders network that is meant to help those interested in promoting conservation obtain the networking and professional skills necessary to influence not only research but policy and sustainability outcomes. During these meetings, OSARA President Dr. Christopher Anderson was asked to give a talk at CENPAT on Long-Term Socio-Ecological Research Sites: Conceptual Foundations and Projections in Argentina, which is part of the information recently published in English and Spanish in the August edition of Austral Ecology. Dr. Anderson led a team of 17 co-authors from Chile, Argentina and the US in an effort to establish a joint agenda on LTSER in the Southern Cone.

25th Annual Meeting of the Argentine Ecological Association

The Argentine Ecological Association (AsAE for its acronym in Spanish) will carry out its 25th annual meeting from 24-28 September in the city of Lujan. This year’s meeting coincides with the 40th anniversary of AsAE and is dedicated to “where we’ve come from; where we’re going”. OSARA has officially sponsored this meeting, specifically providing financial support for relevant symposia and activities related to our mission to promote research, education and conservation in southern Patagonia.

Sustainable Forestry – Lessons from Tierra del Fuego for the World

Working with a distinguished team of international colleagues, Guillermo Martinez Pastur recently published a global review article on sustainable forestry in BioScience, one of the most read journals in biological sciences. The article places particular emphasis on the example of Tierra del Fuego, where the Forestry Resources Lab at the Austral Center for Scientific Research (CADIC, Ushuaia, Argentina) has pioneered the harmonization of use and conservation in forested ecosystems since the 1990s.


Article Abstract: The majority of the world’s forests are used for multiple purposes, which often include the potentially conflicting goals of timber production and biodiversity conservation. A scientifically validated management approach that can reduce such conflicts is retention forestry, an approach modeled on natural processes, which emerged in the last 25 years as an alternative to clearcutting. A portion of the original stand is left unlogged to maintain the continuity of structural and compositional diversity. We detail retention forestry’s ecological role, review its current practices, and summarize the large research base on the subject. Retention forestry is applicable to all forest biomes, complements conservation in reserves, and represents bottom-up conservation through forest manager involvement. A research challenge is to identify thresholds for retention amounts to achieve desired outcomes. We define key issues for future development and link retention forestry with land-zoning allocation at various scales, expanding its uses to forest restoration and the management of uneven-age forests.

OSARA Collaborates on Atlas for Tierra del Fuego

In collaboration with the University of Magallanes’ GIS Laboratory, coordinated by Dr. Sergio Opazo, OSARA has been collaborating in the development of a thematic atlas for the Tierra del Fuego Archipelago to highlight tourism, ecological and cultural attractions. The project, funded by a FIC-R grant directed by Ernesto Davis, intends to produce high quality visual material and content in a bilingual book format, which is expected to be published in 2012. OSARA has coordinated the writing of the chapter entitled “Sub-Antarctic Ecology,” including the collaboration of 6 co-authors from the U.S., Chile and Argentina who synthesize a decade of first hand research and information on the region for a general audience, as well as to promote sustainable tourism.

OSARA’s International Coordinator Named to Post as Wildlife Research Director for Southern Patagonian National Parks

Dr. Alejandro Valenzuela, who has been OSARA’s International Field Course Coordinator since 2010, was recently named the coordinator of wildlife research for Argentina’s southern Patagonian national parks. His position, based in Ushuaia, Tierra del Fuego, will assist the regional director in the planning and execution of studies and management of parks in Tierra del Fuego, Santa Cruz and Chubut Provinces. Specifically, Dr. Valenzuela will bring to bear his expertise in invasive species to determine management and control options for the protected areas, as well as help to design long-term monitoring and research priorities to better use the parks as a network of study sites and to improve their sustainable use. Congratulations Alejandro and this opens a whole new host of opportunities to link research with management throughout Patagonia and its links as well to existing OSARA activities.

Socio-Ecological Research Advances in Tierra del Fuego

Jean-Paul Zagarola, a Master’s of Science in Biology student at the University of North Texas, recently defended his thesis entitled “A Socio-Ecological Analysis of Southern Patagonian Watersheds”. Zagarola’s research, which was funded by a Fulbright Scholarship and a National Science Foundation grant (OISE 0854350), was the first in the region to combine empirical scientific ecological methods with social science surveys to link the “ability” of watersheds to provide ecosystem services, and the way that the local community perceives and values these services. In this way, the work is meant to combine social and ecological information to determine whether or not existing management plans are meeting social needs and expectations, thereby integrating ecology and social well being.

New Publication on Invasive Species Management in Tierra del Fuego

Collaborators from OSARA, the University of Magallanes, Patagonia Wildlife Ltda, and the Chilean Agriculture and Livestock Service recently published a new article in the journal Anales Zoologici Fennici. The study, which was based on the research conducted by Ernesto Davis for his undergraduate thesis, helps resolve important technical issues regarding the implementation of effective trapping for invasive mink in Tierra del Fuego. The findings show that it is possible to conduct trapping that does not affect non-target species by applying relatively simple modifications to the trap design. This project also illustrates the successful collaborations that OSARA promotes between the academic and governmental/management sectors.

New Fulbrighter in Tierra del Fuego!

OSARA is proud to announce that Jon Henn (B.S. Biology, St. Olaf College) has been awarded a Fulbright Scholarship to conduct research in Tierra del Fuego on riparian forest regeneration in areas affected by invasive beavers. Under the mentorship of Dr. Christopher Anderson of OSARA and Drs. Guillermo Martinez Pastur and Vanessa Lencinas at the Austral Center for Scientific Research (CADIC) in Ushuaia, Mr. Henn will conduct a year-long study that integrates plant physiological and ecological information to better understand the potential to actively promote regeneration of riparian forests in Tierra del Fuego that have been degraded by beavers. Together, this team is applying for additional research funding for the project from National Geographic and the Argentine Ministry of Agriculture, while one research grant has already been secured from the Argentine Science and Technology Agency.
