Abstract During an ecology and environmental science field studies course, students were are able to survey the physical and biological processes in two locations within Chile. During the winter break, a group of students went to Chile to expand their knowledge of ecology and environmental science. Field techniques, methodologies, ecosystem dynamics, issues in natural resource management, and conservation were introduced in this course. During the trip students conducted multiple transects, observed the wildlife, water sampling, and took part of ecotourism opportunities. The students interacted with the professors and students in the University of St. Thomas in Osorno and Santiago. We surveyed two locations in Chile: Rio Clarillo National Reserve and Puyehue National Park. Prior to the Chile trip, students practiced surveying different plant and animal species by using cards which was distributed in a patterned way around the UST academic mall in Houston. These cards included organisms that would be inventoried at the locations in Chile. The group identified plant species, marked distances, and took photos. Line transect survey techniques were used to estimate population density for a variety plant species in the two different Chilean biomes. The purpose is to use the data to determine the biome we are currently in and to monitor the species. The two transect locations represented the Mattoral and Valdivian temperate rainforest biomes in Central and Southern Chile.

In the class, students learned about history of Chile, plate tectonics and South America, biomes of Chile, plants of Chile, animals of Chile, and field work. Field techniques, methodologies, ecosystem dynamics, issues in natural resource management, and conservation were introduced in this course. Summary of the Trip Rio Clarillo Reserve Puyehue National Park Conclusion Climate Rio Clarrillo Mediterranean climate (Mattoral) warm to hot, dry summers and mild to cool, wet winters Puyehue National Park Valdivian temperate rain forests High rainfall Biodiversity The Chilean Mattoral is home to many endangered, endemic, and threatened species. Valdivian Temperate rainforest has broadleaf and mixed forests.

The exercise helps students to understand plants species are found in locations of the Chilean biomes.

The two transect locations represented the Mattoral and Valdivian temperate rainforest biomes in Central and Southern Chile. Based on the transects the Chilean Mattoral Biome is the only one that it has no forest zone before the mountains. Therefore, students find this climate dry and hot mainly found shrubland, thicket or bushes in this biome.In Puyehue national at the crater students mostly find little vegetation compared other locations at the national park. In the other locations in the national park vegetation mostly evergreen angiosperms and bamboos. Cards in the academic mall LocationDescriptionName of Plant Rio Clarillo Tall plant with saw grass plant, has budding flower that is purple. Cirsium vulgare Rio ClarilloBlueberry like plant Aristotelia chilensis Puyehue National Park Vegetation in place of grass with flowering buds that are a light purple flower, the green around it is non-blooming. In continuous patches.. Dicot; multiple flowering parts Puyehue National Park White moss on top of green moss on a tree. It’s a skinnier moss that looks like a bare tree branch close up and it is in patches Protousnea poeppigii Date/DayActivities December 27 th,2014 (Day 1)Airport and fly overnight December 28 th,2014 (Day 2)Arrive in Santiago (free day) December 29 th,2014 (Day 3)Introduction to Santiago (city tour) December 30 th,2014 (Day 4)Rio Clarillo National Reserve (Transect) December 31 th,2014 (Day 5)Flight to Osorno January 1 st,2015 (Day 6)Parque Nacional Puyehue (transect) January 2 nd,2015 (Day 7)Rio Bueno January 3 rd,2015 (Day 8)Coastal ecology experience January 4 th,2015 (Day 9)Cabins at Caulin January 5 th,2015 (Day 10)Chiloe(field work in the wetlands) January 6 th,2015 (Day 11)Chiloe(field work in the wetlands) January 7 th,2015 (Day 12)Back at Osorno (final dinner) January 8 th,2015 (Day 13)Osorno to Santiago January 9 th,2015 (Day 14)Final day in Santiago (go back to Houston) January 10 th,2015 (Day 15)Arrive back to Houston
