The Aymara Indians have historically cut down these trees for fuel, and as a result, the Keñua remains only in remote and almost uninhabitable districts.

The unique ecological conditions of the Bolivian Andes support a diverse range of tree species, each with its own characteristics and uses. These trees play a crucial role in the region's biodiversity and contribute to the rich natural heritage of Bolivia.

Bolivia's endangered trees

Bolivia is a country of diverse terrains, with one of the richest biodiversities in the world. The country has a variety of ecological regions, including tropical rainforests, dry valleys, mountainous areas, river basins, and tropical savannas. The country's broad range of altitudes, from 6,542 meters above sea level to 70 meters above sea level, also contributes to its diverse flora.

While Bolivia boasts a vast array of plant species, some face the threat of extinction. The main dangers to endangered plant species are deforestation, invasive species, and climate change. One of the most prominent examples of a threatened tree species in Bolivia is the Mara tree, also known as big-leaf mahogany (Swietenia macrophylla). This tree, which can grow up to 50 meters tall and live for over a century, is native to western South America, including Bolivia. The wood from the Mara tree is highly sought-after for the production of high-end furniture due to its attractive appearance and durability. However, this has led to its endangerment, as illegal logging by "wood pirates" in Bolivian national parks has become a significant issue. Despite efforts by authorities to combat this illegal activity, the high profits involved and the involvement of organised crime syndicates have made it challenging to protect this vulnerable species.

In addition to the Mara tree, other tree species in Bolivia are also facing threats. The Chacoan Guanaco, a native species and one of the largest wild mammals in South America, is endangered due to the loss of its natural food source, the Chaco grasslands. Overgrazing by farmed cattle and infrastructure development have contributed to the eradication of these grasslands, leaving the Chacoan Guanaco's habitat at risk. It is estimated that only 200 Chacoan Guanacos remain in the Bolivian grasslands, with a total of less than 600 across Bolivia, Paraguay, and Argentina combined.

The Spectacled Bear, also known as the Andean Bear, is another species facing threats in Bolivia. This bear, the only surviving bear species in South America, has seen its habitat diminished by deforestation and the development of infrastructure and industry, such as mining and petroleum extraction. Additionally, local farmers hunt these bears to protect their crops, further endangering their population.

The rich biodiversity of Bolivia is a precious resource that requires protection. The country's diverse terrains and ecological regions support a wide variety of plant species, many of which are unique to the region. While some species are resilient and well-adapted to their environments, others are vulnerable to the threats posed by human activities and climate change. Conservation efforts and the enforcement of regulations are crucial to ensuring the survival of Bolivia's endangered trees and maintaining the ecological balance of this biodiverse country.
