Mexico City’s Endemic Species Under Threat: Axolotl, Teporingo, and Sierra Sparrow Face Disappearance
Mexico City, May 16, 2026 – Mexico City boasts a significant diversity of endemic species, meaning those found exclusively in this region and nowhere else globally. This rich biodiversity is intrinsically linked to the lacustrine, forested, and mountainous ecosystems that persist within the urban sprawl, despite intense urbanization.
In observance of Endangered Species Day, the Secretariat of Environment of Mexico City (Sedema) reiterated its commitment to protecting the city’s biodiversity. Unique species such as the axolotl, teporingo, and Sierra sparrow are currently at risk of disappearing. The conservation of these species is crucial for maintaining ecological balance and ensuring the continuity of the region’s urban and rural ecosystems.
Native Species Under Threat and Conservation Actions
The mountain stream axolotl (Ambystoma altamirani), a symbol of the capital’s fauna, faces severe threats from pollution, climate change, and habitat loss. According to Sedema, a professional care colony exists at the UMA El Pantano, located in Desierto de los Leones, where successful reproduction has been achieved under controlled conditions. Wild axolotl populations are also monitored in natural protected areas to assess their status and develop conservation strategies.
The teporingo (Romerolagus diazi), known as the ‘volcano rabbit,’ is another emblematic endangered species. The Directorate of Conservation Centers of the Secretariat of Environment of Mexico City maintains reproductive colonies of teporingo under professional care in the conservation centers of Chapultepec, Los Coyotes, and San Juan de Aragón. These initiatives aim to increase the species’ population and ensure its survival in forests and high-mountain areas.
The Sierra sparrow (Xenospiza baileyi) relies on the integrity of the capital’s grasslands. Support programs have been implemented to protect these habitats and strengthen the communities responsible for their care. Additionally, reforestation efforts, fire prevention, and the promotion of good agricultural practices are underway to safeguard their environment.
Other significant species, such as the transvolcanic long-tailed partridge (Dendrortyx macroura) and the false large maguey (Furcraea parmentieri), are also part of conservation efforts. The partridge is monitored using camera traps in national parks like Desierto de los Leones and Miguel Hidalgo e Insurgente Costilla, obtaining visual records without disturbing its habitat. The false large maguey has been documented through citizen science, identifying its presence in areas such as the Sierra de Santa Catarina, Los Dinamos, and Bosque de Tlalpan.
Summary of Other Key Endemic Species in CDMX:
- Xochimilco Axolotl (Ambystoma mexicanum)
- Altiplano Axolotl (Ambystoma velasci)
- Mountain Stream Axolotl
- Teporingo (Romerolagus diazi)
- New Chapultepec firefly (Photinus sp.)
- Various species of bats, frogs, and reptiles restricted to the altiplano region
These ongoing efforts highlight the dedication of Mexico City’s environmental authorities and local communities to preserve the unique natural heritage that defines this vibrant metropolis.
