This course will examine the origin and persistence of grass páramo, a high-elevation Andean savanna. Páramo covers extensive areas of the tropical Andes in an altitudinal belt between the tree line and the snowline. Despite its remoteness and wilderness aspect, evidence suggests that the development of grass páramo was driven by late Pleistocene hunter-gatherers.
Readings will examine the three data sets available for elucidating the process of grass páramo formation: fossil pollen, sedimentary charcoal and evidence of early hunter-gatherer occupation. The course will then assess how these data support or refute the conventional wisdom that grass páramo is a purely climatic expression or, as argued more recently, the replacement vegetation of a zonal forest removed by early agriculturalists.
A field trip during Spring Break to three grass páramos in Ecuador, in Cajas, Sangay and Chimborazo National Parks, will ground the information acquired in the literature review. In Ecuador, students will walk páramo landscapes and apply their academic preparation to on-the-ground observations and explanations of current tree lines, forest patches above tree line, the dominance of tussock grasses and giant ground rosettes, the frequency and behavior of fire, and plant tolerance to periodic burning. A trip to a desert páramo in Chimborazo National Park, between 13,000’ and 16,500’, will highlight environmental constraints on the plant community.
By the end of the course students will have a deeper appreciation of humans as a keystone species in grass páramo creation and maintenance. They will have applied the lessons of páramo etiology to an enlightened management and conservation of Ecuadorian páramos. Concurrently, students will have developed a sensibility to the weight of history on contemporary vegetation, and to the ubiquitous but sometimes elusive nature of anthropic inputs.
Students will meet with their instructor via BigBlueButton, a Skype-like feature of Blackboard, about one month before Spring Break. This meeting will anticipate the logistics of the field trip, and introduce a list of readings to be completed before traveling to Ecuador.
Students depart for the field trip on the evening of Friday, March 9, 2018, leaving from JFK in a direct flight to Guayaquil. A bus will transport students from Guayaquil to Cuenca the next morning. During the ensuing week, we will visit páramos of the three national parks mentioned. Return travel will be on Sunday, March 18. Students will be advised regarding specific flight arrangements.
Grading will be based on (i) an introductory exam (30%) given after a páramo excursion the first day in Ecuador and based on pre-Spring Break readings, (ii) participation in the field studies during the Spring Break (40%), and a final exam (30%), prior to the return to the U.S. This course is offered through the Geography Department and earns 3 credits.
Students should have at least sophomore standing, and have taken at least one course in ecology, biology, geography, forestry, environmental studies, anthropology, botany or global studies. Exceptions can be made upon consultation with the instructor.
For the field portion of the course, students will be required to walk every day in páramos at elevations of 11,000’ and above. Those who are comfortable at altitude will have the opportunity to hike to 16,500’ on Chimborazo mountain. They must arrive in good physical condition and have adequate boots, hats and clothing for cold, rain and possibly snow. Students will be housed for most of their stay in a rustic field camp at 11,400’ within Sangay National Park.
The instructor, Stuart White, owns and manages the Mazar Wildlife Reserve in the Cordillera Real of Ecuador, where he has lived since 1982. The MWR is dedicated to conserving 1700 hectares of mountainous native habitats and their fauna, financed largely by the husbandry of an alpaca herd pastured at lower elevations. Stuart received a PhD in Geography at the University of Wisconsin in 1981 and subsequently taught Geography at the University of New Mexico, Albuquerque, until moving to Ecuador. In addition to raising alpacas, Stuart has spent his years in two pursuits: First, promoting the reintroduction of this camelid to the Ecuadorian rural economy; and second, as habitat conservation advocate, crystalized in the establishment of the Fundación Cordillera Tropical (www.cordilleratropical.org), which he headed between 2000 and 2010. Since 2010 Stuart has been a lecturer with the Geography Department at the University of Vermont, where he taught during 2011-2012.
