ORAL PRESENTATION

ECOSYSTEM DESCRIPTION - - FEATURES - ISSUES

  1. Read about the ecosystem assigned to your group. Search and choose an specific example of it. read more info about it. Write min 350 words - max 400:
a.The description of the ecosystem (name, location, type of ecosystem, etc). b.Specific features of its biotic and abiotic elements (flora, fauna, soil, temperature, weather coonditions). c.The environmental problems caused by human activities in it. d.Include a graphic - Respect AUTHOR'S RIGHTS. 2. Hand in ON TIME the written work to your teacher - TEAMS 3.Create a poster for your oral activity. All members of the group must present.

Description Example

The Sumapaz landmoor is located in the Altiplano Cundiboyacense mountain range, It surrounds a part of Bogotá, Meta, Huila and some municipalities of Cundinamarca. Its Muisca name means “peaceful moorland”. it is a terrestrial ecosystem with an elevated area of rocky mountains and wet soil. This paramo has a cold, wet, windy and foggy weather and the air is thick with humidity. Temperatures range from −10 °C to 17 °C. This is the world’s largest paramo. You can find in the valleys of the moor freshwater bodies like rivers, crystal clear springs and cold lakes. Sumapaz houses a unique animal and vegetal biodiversity. It is the home of vegetal species like frailejons (some up to 12m tall), mosses and lichens. During the rainy season, these plants soak up the water from torrential rains, this ability to retain water means that the moor can continue to supply local reservoirs even after the weather turns dry. The animals that live in this moor are mammals like spectacle bears, tapirs, coatis, and deers. The spectacle bears are also known as Andean bears, they are considered the second most endangered bear species in the world. Besides, Sumapaz paramo houses birds such as the black golden eagle, tiny and colorful hummingbirds, torrent duck and Paramo duck. In the past, it used to be a clean and sacred place for the Muiscas. But now, the moor is in danger specially due to the growing agriculture and touristic activities in it. Climate change has also increased the risk of fires within this paramo. Research has stablished that fires in Sumapaz are mostly of human origin. They are started to clear vegetation and create open grassland. The higher temperatures and likely drier conditions under climate change in this area will make fires easier to start and harder to control with more frequency in Sumapaz. For instance, in February 2020 a massive fire burned at least 30 square km in the moor. The flames were so bad that the Colombia’s Disaster Risk Management Agency had to attend the disaster. This environemntal catastrophe caused air-pollution alerts in nearby Bogotá. These human activities threaten both the moor ecosystem and its important production of water which is a key resource, especially for the Bogotá savanna.
