The Unsung Hero: Bolivia's Most Vital Plant

Bolivia is a landlocked country in central South America with a diverse range of terrains and ecologies, from tropical rainforests and dry valleys to mountains and river basins. It is home to a wide variety of flora, including the Bolivian Begonia, Yareta, Fire Flag, Creeping Oxeye, and Cuplet Fern. The country's rich biodiversity is reflected in its numerous native plants, which are used for construction, dietary purposes, aesthetic fuel, and medicine.

One of the most important plants in Bolivia is the Puya Raimundi, the largest succulent plant in the world, with a flower stem that can reach up to 12 meters in length. This plant is so special that it takes a hundred years for it to flower. Another significant plant is the potato, which is widely cultivated in the Andes and has over 200 species. The yuca, maize, and quinoa are also important food sources for the people of Bolivia.

The country's geographic variation and diverse climates provide a unique habitat for a vast array of plant species, making it challenging to pinpoint a single plant as the most important. However, the Puya Raimundi and the potato certainly stand out as two of the most notable and significant plants in Bolivia.

Bolivia's native plants

Bolivia is a landlocked country in central South America with one of the richest biodiversities in the world. The country's geography varies significantly, from the Andean mountain range in the west to the eastern lowlands situated within the Amazon basin. This enormous geographic variation results in a wide array of native plants.

The Bolivian Andes, for example, are home to the Bolivian Begonia, a tuberous plant that grows in rock crevices and near streams. It has fiery orange flowers and is used for landscaping. Another plant found in the Bolivian Andes is the Yareta, a slow-growing evergreen plant that produces lavender flowers and is well-adapted to poor nutrition and acidic or alkaline soils. Yareta is also found in the high grasslands of Peru, Chile, and Argentina, and some plants are estimated to be 3,000 years old.

In the tropical rainforests of the Amazon basin, one can find the quina tree, which produces quinine, and the Pará rubber tree. There are also over 2,000 species of hardwoods, as well as vanilla, sarsaparilla, and saffron plants. Palms, sweet potatoes, manioc, peanuts, and a wide variety of fruits are also native to this region.

The Altiplano, a high plateau in the Andes, does not support much plant life due to the cold temperatures and low rainfall. However, low shrubs, cacti, succulents, mosses, and yellow grass pollen can be found here. The keñua tree species is particularly noteworthy as it can survive at altitudes of up to 5,200 meters.

The Yungas, or eastern mountain slopes, are covered with cloud forests, ferns, mountain bamboo, and subtropical forests with orchids, bromeliads, and palms. Many small trees and lianas grow under the gigantic trees of the tropical rainforest, along with begonias and paradise flowers or heliconias.

The Chiquitania, a unique ecoregion in eastern Bolivia, is the world's largest intact tropical dry forest. It is a transition zone between the Amazon rainforest and the dry Chaco forests and provides many ecosystem services, with rural communities depending on it for their livelihoods. The Chiquitania is home to iconic plants such as giant water lilies and fire-resistant trees.

Other notable native plants of Bolivia include the Mistol, which produces edible fruits and wood used for tools and fuel, and the Puya Raimundi, the largest succulent plant in the world with a flower stem up to 12 meters long.

The Chiquitania dry forest

The Chiquitania is characterised by three distinct habitats: the Pantanal, the Cerrado, and the Chiquitania dry forest itself. The Pantanal, the world's largest tropical wetland, is known for its iconic giant water lilies. The Cerrado is a savanna landscape consisting of shrubs, grasses, spiny and fleshy plants, and fire-resistant trees. Meanwhile, the Chiquitania dry forest boasts an impressive array of plant species, with 3,500 plants recorded so far, 244 of which are globally endemic.

However, the Chiquitania dry forest is highly vulnerable to the impacts of climate change and human activities. Droughts and fast-spreading fires pose significant threats to the region, and deforestation has increased dramatically in recent decades due to agricultural expansion. To protect this ecologically rich region, organisations like Kew have partnered with local institutions in Bolivia to identify globally important sites for plants and habitats that are unique to the Chiquitania and require conservation.

The Cerrado savanna

Bolivia is a country of diverse terrains, with a wide range of ecologies, from tropical rainforests to dry valleys, mountainous areas, river basins, and tropical savannas. The Cerrado savanna is one of these ecologies.

The Cerrado is a savanna that is comprised of shrubs, grasses, spiny and fleshy plants, and fire-resistant trees. This unique habitat supports a wealth of animal and plant species. The savanna is also home to many indigenous communities who depend on it for their livelihoods.

The Cerrado is vulnerable to drought and fast-spreading fires, which have been worsened by climate change and deforestation. In 2019, huge human-made uncontrollable fires swept through the savanna, potentially devastating the ecosystem.

The Cerrado is also under threat from soybean and cattle farming. Scientists and conservationists have been working to identify habitats and plants within the Cerrado that need protection. They have recorded over 3,500 plant species, of which 244 are globally endemic.

Some of the unique plant species found in the Cerrado include:

• Fire-resistant trees with corky bark
• Hippeastrum lily, which flowers after forest fires
• Shrubs
• Grasses
• Spiny plants
• Fleshy plants

The Pantanal wetland

The name "Pantanal" comes from the Portuguese word "pântano", meaning swamp, wetland, bog, quagmire, or marsh. The region is characterised by its gently sloping basin, which receives runoff from the upland Planalto highlands and slowly releases water through the Paraguay River and its tributaries. The Pantanal's formation is a result of a large, concave, pre-Andean depression in the Earth's crust, influenced by the Andean orogeny of the Tertiary period.

The Pantanal encompasses various subregional ecosystems, each with distinct hydrological, geological, and ecological characteristics. During the rainy seasons, about 80% of the Pantanal floodplains are submerged, fostering a diverse array of aquatic plants and supporting a dense population of animal species. The vegetation of the Pantanal, often referred to as the "Pantanal complex", includes a mix of plant communities typical of surrounding biomes, such as moist tropical Amazonian rainforest plants, semiarid woodland plants of northeast Brazil, Brazilian Cerrado savanna plants, and plants of the Chaco savannas of Bolivia and Paraguay.

The Bolivian Pantanal, surrounded by dry Chiquitano and Chaqueño Forests, boasts impressive biological diversity. Approximately 1,700 plant species have been identified in the Brazilian section, and research in Bolivia continues to uncover unique species. The Pantanal ecosystem is known for its rich wildlife, including capybaras, alligators, and a spectacular variety of aquatic birds.

The wetland has two protected areas established in 1997: Otuquis in the southeast and San Matías in the northeast. The town of Puerto Suarez is located in this area, and it serves as the starting point for expeditions into the Bolivian Pantanal. Visitors can explore the rivers and lagoons, observe wildlife, and engage in birdwatching, camping, or lodging in basic accommodations.

The Yungas cloud forests

Bolivia is a country of diverse terrains, with a wide range of ecologies, from tropical rainforests to dry valleys, and mountainous areas to river basins. The country's enormous geographic variation means that Bolivia has many native plants, including the Bolivian Begonia, Yareta, Fire Flag, Creeping Oxeye, and Cuplet Fern.

The Yungas is a transitional zone between the Andean region and the Amazon basin. The Andean region is characterized by its puna vegetation, which includes thorn bushes and cacti, while the Amazon basin is home to tropical rainforests. The cloud forests of the Yungas provide a habitat for a diverse range of plant and animal life, including many species found nowhere else on Earth.

The cloud forests of the Yungas are an important source of water for the region, as they capture moisture from the clouds and release it slowly into the soil and waterways. This helps to maintain the local water supply and prevents flooding during the rainy season. The cloud forests also play a crucial role in carbon sequestration, absorbing carbon dioxide from the atmosphere and storing it in their dense vegetation.

The Yungas is home to a number of indigenous communities who have lived in the area for centuries. These communities have a deep knowledge of the local plant and animal life and have developed sustainable practices to manage their natural resources. However, in recent years, the Yungas has come under threat from deforestation and climate change, which have led to a loss of habitat for many plant and animal species.

The Bolivian government has recognized the importance of the Yungas cloud forests and has taken steps to protect this unique ecosystem. In collaboration with international organizations, the government has implemented conservation measures and supported sustainable development initiatives in the region. These efforts aim to preserve the rich biodiversity of the Yungas and ensure that local communities can continue to benefit from its natural resources in the long term.
