Protected Areas of La Paz Could Be Part of an Ecological Corridor

At the closing of the project that began in September 2024 and included phases such as wildlife monitoring and ecological and urban connectivity, the possibility was raised that the city of La Paz could encompass an ecological corridor including municipal protected areas (MPA) such as the Pura Pura woodland and the Auquisamaña mountain ranges.

“What we have done is identify biodiversity core sites and see how these can be connected through the urban matrix, and within that matrix determine how species could be moving from one site to another, how they are moving, and whether those biological corridors are being effective,” said Rhaiza Cortez, coordinator of the project carried out by the environmental platform “Ciencia Molotov.”

An ecological corridor is considered something like a “nature highway” that increases biodiversity and resilience and mitigates the effects of fragmentation caused by climate change driven by human greed: it is equivalent to “a strip of vegetation, a natural route that connects fragmented habitats, allowing the safe movement, migration, and exchange of various species.”

“Possibly La Paz could itself be an ecological corridor. It could be—it’s kind of a crazy idea—but it could happen that the Pura Pura woodland and the Auquisamaña woodland might connect, not entirely, but at some point species could spread from certain locations, pollinators for example; therefore green areas are very important,” said Carola Copa, who in the project worked on collecting data on vertebrates.

The project “Revitalization of the Municipal Protected Area of Auquisamaña” was developed by the platform Ciencia Molotov, the World Wide Fund for Nature (WWF by its English acronym), and the Embassy of Sweden in Bolivia. Among other materials, it produced a manual for monitoring biodiversity in the Auquisamaña MPA, brochures on wildlife connections, and mini-guides to birds and butterflies.

Land parceling and earthmoving

It should be recalled that the municipal protected area Bosquecillo and Serranías de Auquisamaña covers more than 101 hectares. It is located in the dry valleys and puna ecoregion between 3,300 and 3,800 meters above sea level, offering interpretive trails, recreational areas, native flora and fauna where, among other activities such as trekking, birdwatching tourism can also be practiced (see “Advances of the Revitalization Project of the Municipal Protected Area of Auquisamaña Presented,” 06/04/25).

In order for the competent authorities to act in favor of that protected area, it is necessary to stress that the sector is threatened by factors that undermine its integrity, its biodiversity, and the environmental services it provides, referring to the constant leveling and earthmoving generated by land parceling and the extraction of aggregates (see “Private property? A barrier of earthmoving threatens the protected area of Auquisamaña,” 08/10/22, ANA; “Logging and destruction of flora continue in the Auquisamaña woodland,” ANA, 06/20/21).

“They are bringing down a lot of material, machinery that is really affecting the area a great deal, but nothing can be done because it is not part of the protected area, yet it affects it. In this connectivity project, in this final part, the idea is to see how the protected area connects with other green areas, and by bringing down these blocks of earth, trying to level the terrain and so on, they are eliminating habitats that are important for fauna and flora and are displacing animals to other places or they are simply dying,” Copa emphasized.
