Factors of biodiversity transformation and loss

201

Threatened Reptiles of Colombia

The evaluation of the reptilian species of Colombia shower that 50 % of crocodilian and 37 % of turtle species are theatened and there is not enough information to categorize 20 % of all reptile species. It therefore necessary to strengthen conservation and management efforts for threatened species, as well as develop more research concerning those that lack information.

Plant Groups of Conservation Interest

All species of tropical cycads and magnoliids, in addition to 20 % of palms, are under some threat category. Also, 36 species that are endemic to the tropical dry forest are endangered. In this scenario, it is essential to implement conservation actions for these species and include them in restoration plans.

203

Species Composition and Changes in Land Use

In the country, biodiversity has on average decreased by 18% due to changes in the use of the land. This number could increase if current patterns of exploitation and consumption are maintained.

204

Threatened Species in Colombia

The red list index shows a greater extinction risk for species globally threatened in colombia and alerts about the need to work on achieving target 12 of the strategic plan of the convention on biological diversity in the coming four years.

205

Climate Change and Extinctions on Mountain Summits

The complex topography of the andes mountain range restricts the altitudinal movements that species may have in response to climate change. This phenomenon could increase the number of threatened species in tropical mountains and cause extinctions.
