Named for Thomas van der Hammen

The Thomas van der Hammen Natural Reserve or Thomas van der Hammen Forest Reserve is an area of the Bogotá savanna that is under environmental protection. The natural reserve was declared as such in year 2000 by the Ministry of Environment and Sustainable development. [1] It takes its name from the Dutch-Colombian geologist Thomas van der Hammen who devoted his life to the research of the region. The surface area of the protected reserve is approximately 1,395 hectares (3,450 acres) and it is located in the north of Bogotá.

Bogotá savanna

The Bogotá savanna is a montane savanna, located in the southwestern part of the Altiplano Cundiboyacense in the center of Colombia. The Bogotá savanna has an extent of 4,251.6 square kilometres (1,641.6 sq mi) and an average altitude of 2,550 metres (8,370 ft). The savanna is situated in the Eastern Ranges of the Colombian Andes.

Thomas van der Hammen Dutch botanist (1924-2010)

Thomas van der Hammen was a Dutch palaeontologist, botanist and geologist. He has published more than 160 works in five languages.

Contents

The protection area has the purpose of creating an urban forest that connects the Bogotá River and the Eastern Hills of Bogotá, to preserve the underground water sources, improve the quality of the air and protect the diversity and activities of the animal species that exist there. [2] [3]

Bogotá River River in Colombia

The Bogotá River is a major river of the Cundinamarca department of Colombia, crossing the region from the northeast to the southwest and passing along the western limits of Bogotá. The large population and major industrial base in its watershed have resulted in extremely severe pollution problems for the river.

Eastern Hills, Bogotá

The Eastern Hills are a chain of hills forming the eastern natural boundary of the Colombian capital Bogotá. They are part of the Altiplano Cundiboyacense, the high plateau of the Eastern Ranges of the Colombian Andes. The Eastern Hills are bordered by the Chingaza National Natural Park to the east, the Bogotá savanna to the west and north, and the Sumapaz Páramo to the south. The north-northeast to south-southwest trending mountain chain is 52 kilometres (32 mi) long and its width varies from 0.4 to 8 kilometres. The highest hilltops rise to 3,550 metres (11,650 ft) over the western flatlands at 2,600 metres (8,500 ft). The Torca River at the border with Chía in the north, the boquerón Chipaque to the south and the valley of the Teusacá River to the east are the hydrographic limits of the Eastern Hills.

Mayor of Bogotá Enrique Peñalosa has proposed construction in the Reserve that could host 1.5 million people. [4]

Enrique Peñalosa Colombian politician

Enrique Peñalosa Londoño is a Colombian politician. He was mayor of Bogotá from 1998 until 2001, and was re-elected in 2015 for the 2016–2019 term. He has also worked as a journalist and consultant on urban and transportation policy. In 2009, Peñalosa was elected president of the board of directors of the Institute for Transportation and Development Policy (ITDP), a non-profit organization headquartered in New York. Peñalosa resigned from the ITDP board in 2015 upon his election.

Flora and fauna

The Thomas van der Hammen Natural Reserve is a rich natural area important for the biodiversity of the Bogotá savanna. Several endemic species have been registered, and two newly described species of butterflies were discovered in the Reserve. [5]

Biodiversity of Colombia

Colombia is the country with the second-highest biodiversity in the world, behind Brazil. As of 2016, 56,343 species are registered in Colombia, of which 9,153 are endemic. The country occupies the first position worldwide in number of orchids and birds, second position in plants, amphibians, butterflies and fresh water fish, third place in species of palm trees and reptiles and globally holds the fourth position in biodiversity of mammals.

Fauna

Birds

In the area of the reserve 187 species of birds have been registered, some of which are endangered. [6] [7] Two species, registered in the past; Cistothorus apolinari and Polystictus pectoralis have not been reported recently. [8]

Mammals

Registered mammals are among others guinea pigs, Andean white-eared opossum (Didelphis pernigra), [5] tigrillo (Leopardus tigrinus), [9] long-tailed weasel (Mustela frenata), [10] and eleven species of bats. [11]

Guinea pig domesticated rodent species from South America

The guinea pig or domestic guinea pig, also known as cavy or domestic cavy, is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, guinea pigs are not native to Guinea, nor are they biologically related to pigs, and the origin of the name is still unclear. They originated in the Andes of South America, and studies based on biochemistry and hybridization suggest they are domesticated descendants of a closely related species of cavy such as C. tschudii, and therefore do not exist naturally in the wild. They were originally domesticated as livestock, as a source of food, and continue to be.

Andean white-eared opossum species of mammal

The Andean white-eared opossum is an opossum species from South America. It is found in the Andes Mountains, ranging from Venezuela to Bolivia.

Long-tailed weasel species of mammal

The long-tailed weasel, also known as the bridled weasel or big stoat, is a species of mustelid distributed from southern Canada throughout all the United States and Mexico, southward through all of Central America and into northern South America. It is distinct from the short-tailed weasel, also known as a "stoat", a close relation which originated in Eurasia and crossed into North America some half million years ago.
