Argentina and Chile Decide Not to Leave it to Beavers.

Importing the incisor-toothed hydrologists from Canada to the southernmost tip of South America seemed like a good idea in 1946, but it wasn’t. 

Rarely has the inception of an environmental disaster been so triumphantly documented.

In a recently unearthed black-and-white newsreel, which played before movies in theaters across Argentina in 1946, a newscaster reported that 20 beavers have been trapped in Canada and flown to Tierra del Fuego—the island that straddles the border between Argentina and Chile at the southernmost tip of South America. Argentine Pres. Juan Perón’s administration had imported the animals in hopes that they would thrive and reproduce, fostering a fur trade in the economically lackluster territory. “The beavers, who eat branches of trees and bark, will find abundance here,” the newscaster stated, as the camera pans across kilometers of virgin Fuegian forests. The beavers, released from their cages, slip into a river as the voice added gravitas to the dam-building beasties’ entry into their new environs, “Now they are in God’s hands.”

Abundance they found. Six decades later the descendants of those 20 pioneers number in the tens of thousands in Patagonia. The beasts have swum from Tierra del Fuego to the continent and beyond, and now occupy an unknown number of islands in the vast uninhabited archipelago off the coast of southern Chile. As they waddle their way north, building dams, creating ponds and procreating, they lay waste to vast tracts of land, which appear scorched or bulldozed. The destructive power of the beavers in Patagonia surprised ecologists in North America, where the same animals have been reintroduced to wetlands in need of restoration. Read more by clicking here.

Science and Tourism Unite Tierra del Fuego

100_0259Scientists from the University of Magallanes in Chile have teamed up with colleagues in Argentina at the National Parks Administration, the National University of Tierra del Fuego and the Austral Center for Scientific Research to develop an innovative project that links science & tourism and bridges the historical gap between the two countries in the Tierra del Fuego Archipelago. In general, such collaborative ventures are considered “outreach,” whereby the scientific organization “helps” the private sector. In this project, funded by the Chilean Science and Technological Commission – CONICYT, the dialogue is reciprocal; scientists not only are training local tourism guides, but also involving them in the research and monitoring projects in the archipelago.

The goal is to value the deep knowledge and capacity of the tourism industry to generate new information, monitor its own impacts and provide a service to the academic community by helping implement a monitoring and sampling network in remote parts of Tierra del Fuego, where few scientists venture. Working in this pilot effort with the company Cruceros Australis, the project’s directors have begun five new data collection protocols: a) following of plant phenology, b) description of intertidal marine communities, c) monitoring of invasive species and birds, d) sampling ocean chemistry and e) recording trash throughout the navigation routes. In this way, scientists and the private sector hope to promote a binational approach to sustainable development options via ecotourism and also implement much needed long-term research and monitoring in one of the world’s most remote archipelagos.

Perceiving Patagonia


Jean-Paul Zagarola and colleagues from the U.S.A. and Argentina recently published the cover article in the journal Environmental Management entitled  “Perceiving Patagonia: An Assessment of Social Values and Perspectives Regarding Watershed Ecosystem Services and Management in Southern South America.” This research, which was funded by a Fulbright student grant and a U.S. National Science Foundation IRES award, was the first of its kind by simultaneously exploring the mentalities of “regular citizens” and “specialists” on both sides of the Fuegian Archipelago.

Research on human dimensions of ecosystems through the ecosystem services (ES) concept has proliferated over recent decades but has largely focused on monetary value of ecosystems while excluding other community-based values. This study conducted 312 surveys of general community members and regional researchers and decision makers to understand local perceptions and values of watershed ES and natural resource management in South America’s southern Patagonian ecoregion. Results indicated that specialists shared many similar values of ES with community members, but at the same time their mentalities did not capture the diversity of values that existed within the broader community. The supporting services were most highly valued by both groups, but generally poorly understood by the community. Many services that are not easily captured in monetary terms, particularly cultural services, were highly valued by community members and specialists. Both groups perceived a lack of communication and access to basic scientific information in current management approaches and differed slightly in their perspective on potential threats to ES.

New Book on Chilean Biosphere Reserves as “Sustainability Laboratories”


After several years of research and preparation, Drs. Andrés Moreira (P. Univ. Católica, Chile) and Axel Borsdorf (Univ. of Innsbruck, Austria) have published an edited volume, entitled Chilean Biosphere Reserves – Laboratories for Sustainability, which includes conceptual and practical analyses of how to compatibilize human well-being and environmental conservation and provides descriptive case studies for the 10 biosphere reserves found in Chile. Dr. Christopher Anderson was invited to contribute the chapter on Cape Horn.

Two of the World’s Iconic Landscapes Together in One New Project for Research and Sustainability

2013-01-18 18.42.42So, what do the Grand Canyon and Patagonia have in common? Well, they are both places whose names evoke iconic imagery of some of the world’s most amazing landscapes. Now, they are also the sites of a binational project funded by the U.S. National Science Foundation entitled Patagonia Research Experiences for Students in Sustainability (PRESS):  Understanding Social-Ecological Drivers & Consequences of Global Change.

This project will fund up to 8 students per year from Northern Arizona University to conduct research with mentors based at the Austral Center for Scientific Research, the Argentine National Parks Association, the National University of Southern Patagonia and the National University of Tierra del Fuego to study i) climate and land use change, ii) invasive species and iii) tourism/development in protected areas.

OSARA Facilitates First Patagonia Graduate Course on “Socio-Ecology”

DSC_0713Between 9-14 December 2013, 19 student participants came together in the Austral Center for Scientific Research (CADIC) to participate in a course organized by the National University of Tierra del Fuego in conjunction with the Department of Forest Resources and Environmental Conservation at Virginia Tech. The course, entitled “Integrating Human and Natural Dimensions to better Study and Conserve Socio–Ecological Systems,” brought together professors from the U.S. and Argentina and students from Argentina, Chile, U.S. and Columbia to explore what and how to incorporate humans not only into our studies of the world, but also the very way we conceive nature and the “human-nature” relationship.

OSARA Sponsors Socio-Ecology Symposium at 5th Chile-Argentina Binational Ecology Meeting

IMG_0317Socio-ecology: advancing towards the integration of the “human dimension” in the study and understanding of ecosystems in southern South America. 5th Binational Ecology Meeting, Puerto Varas, Chile. Salón Osorno, Hotel Patagónico, 8:30-11:30, 5 November 2013

The objective of this panel was to analyze how the study and management of socio-ecological topics can generate a greater understanding and favor the search for solutions at the local/regional level. Through presentations, discussions and associated posters, this symposium seeks to achieve a revision and analysis of the conceptual and methodological advances that are necessary to achieve a true and effective integration between natural and social sciences and the humanities. From this symposium, we hope to generate proposals that contribute to the projection of socio-ecology in Chile and Argentina as well as a Latin American and global scale. A manuscript for the Debates section of Ecologia Austral is currently in preparation by the symposium participants.

Research Center Expands in Tierra del Fuego

Wampliacion cadicith more than 30 years of history, the Austral Center for Scientific Research (CADIC for its initials in Spanish) is the major research center in the Tierra del Fuego Archipelago and indeed for southern Patagonia’s sub-Antarctic ecoregion. Hosting more than 100 scientists, technicians, students and support staff, CADIC works in a diverse array of areas, ranging from forestry, geology, archaeology, international relations, outreach, ecology and horticulture. Now, with an investment of nearly $2 million USD, the research institute has nearly doubled its space. The inaugural ceremony was presided over by President Cristina Fernandez by videoconference and the physical presence of Provincial Governor Fabiana Rios, demonstrating the highest political support for research in Tierra del Fuego, but also was attended by local scientists and citizens of Tierra del Fuego. For more information: CONICET website.

National Invasive Species Strategy

APNThe Argentine National Parks Service organized a workshop from 2-4 May in Calafate, Santa Cruz Province to advance a national strategy for invasive species. Organizers from the National Conservation Office lead participants from throughout the country’s regional scientific offices in progressing the formation of a national agenda that will complement similar efforts being advanced by the National Secretary of Environment and Sustainable Development. The event permitted authorities from diverse parts of Argentina to come together and recognize common threats and plan methodologies that will allow them to more effectively deal with the problem of introduced and invasive flora and fauna.

Tierra del Fuego Promoting Integrated Education

UNTDFThe recently launched National University of Tierra del Fuego has taken on several major challenges.  Not only is it the world’s southernmost institution of higher learning, but it has also taken on the challenge of meeting modern societies needs and placing its universities at the forefront of leading the development of the territory. One way this is being accomplished is by having all incoming students attend a course entitled “Introduction to the Study of Society, Culture and Environment”. UNTDF also is constituted by 4 interdisciplinary institutes, rather than the traditional “faculty” system made up of established fields of study within specific domains. In this way, the university is working to not only break rigid academic structures but also make sure that its work is relevant for social and environmental realities of Tierra del Fuego.



Enhancing the Link between Science and Society

100_0259Increasingly science funding agencies around the world are recognizing the need to link academic research and private and public sectors. Chile’s national science and technology commission (CONICYT) recently created a program to encourage precisely that type of linkage. One of the selected projects was presented by Dr. Silvia Murcia and Ernesto Davis, previously the beneficiary of an OSARA scholarship to conduct his masters. Their proposal, entitled Scientific-Technological Transfer for the Training of the Tourism Sector in the Magallanes and Chilean Antarctic Region, includes the participation of COMAPA, one of the major tourism companies in southern Patagonia. Over the course of a year, this co-financing of CONICYT and COMAPA will allow a systematic training regime to be implemented for the company’s guides. However, a novel aspect of the program will be not merely to teach the guides scientifically-related topics, but also to train them to become monitors within the national parks they visit to collect important (and hard to access) data and also as a “real-time” feedback mechanism for the company itself to evaluate and improve its practices, such as environmental impact but also the development of new narratives and content for the offerings provided to tourists. OSARA’s role in the project will be to advise the development of monitoring criteria and protocols and training for guides in the area of sustainable development and conservation.

Canadian Researchers Initiate Collaboration in TDF

cherieA group of five eco-hydrologists and riparian restoration specialists, led by Dr. Cherie Westbrook at the University of Saskathchewan, visited Tierra del Fuego from mid-February to mid-March to initiate a collaboration with the Austral Center for Scientific Research, the National University of Tierra del Fuego and the Argentine Administration of National Parks. Their team based their work in Tierra del Fuego National Park and started a long-term study of the effects of beavers on the hydrology and geomorphology of Tierra del Fuego’s watersheds. Ultimately, these results will be crucial to understand how and if riparian ecosystems can be restored upon beaver removal. An associated project, led by Dr. Colin Whitfield, studied the effects of beavers on carbon dynamics, specifically emission of methane. These results too will prove crucial in filling gaps in our current knowledge and understanding about the impacts of beaver invasion in southern Patagonia, particularly as they relate to carbon storage and sequestration.

Tierra del Fuego Set to Conform Network with “Archipelagic” Universities

UNTDFAs part of the Argentine Ministry of Education’s efforts to increase networking capacity of its universities, the National University of Tierra del Fuego (UNTDF) recently was awarded a project to lead the conformation of a network of “archipelagic” universities that include the University of the West Indies with various campuses throughout the Caribbean and the Universidad de La Laguna in Tenerife, Canary Islands, Spain. The proposal includes plans to work over the coming year to define the areas between these universities where collaborative projects can be developed in the areas of student exchange, territorial development, and environmental management/conservation with a specific emphasis on how each of these axes interface with the particular condition of being found in an archipelagic setting.

Birder’s Exchange Supports Avian Research in Tierra del Fuego

In January, the Program Director o2012-12-28 08.21.46Birder’s Exchange (BEx) Betty Petersen visited southern Patagonia on a trip organized by Mass Audubon. During that trip, she provided a BEx donation of binoculars and reference books on bird banding to support the long-term ornithological research coordinated by Tierra del Fuego National Park and the Austral Center for Scientific Research (CADIC). OSARA is proud to help facilitate the relationship between the American Birding Associations BEx Program and conservation and research agencies in southern Patagonia. This important contribution will help not only researchers and park rangers conduct their work, but also provide opportunities for tourism operators and lay people to be involved in the projects taking place in Tierra del Fuego.
