The Pecos pupfish faces extinction from invasive species and pollution. Act now to save this unique species and protect our vital ecosystems for future generations.


The Pecos pupfish (Cyprinodon pecosensis) is facing extinction. This tiny fish, less than two inches long, calls the Pecos River Basin in New Mexico and Texas home. Once widespread, the pupfish now struggles to survive amidst mounting threats1.

Invasive Species Devastate Native Populations

Invasive sheepshead minnows, introduced in the 1970s and 1980s, have devastated the pupfish population. These minnows breed with the Pecos pupfish, creating hybrids that outcompete the native species for resources2. The resulting hybrid fish are larger, grow faster, and dominate the habitat, leaving little room for the purebred pupfish to thrive3.

Climate Change and Pollution Threaten Survival

Climate change exacerbates the situation by reducing surface water availability and degrading water quality. Rising temperatures and altered precipitation patterns threaten the delicate balance of the river ecosystem, making it harder for the pupfish to survive1. Additionally, oil and gas extraction activities in the region lead to groundwater depletion and pollution, further diminishing the pupfish's already limited habitat1.

The U.S. Fish and Wildlife Service (FWS) has taken a crucial step by proposing to list the Pecos pupfish as a threatened species under the Endangered Species Act. This proposal includes designating 136 river miles and over 26,000 acres of critical habitat in New Mexico and Texas4. These areas are essential for the pupfish's survival and will receive protections to prevent further habitat loss and degradation5.

Conservation Efforts in Action

Conservation efforts are underway to save the Pecos pupfish. The Texas Parks and Wildlife Department is leading initiatives focused on captive propagation and genetic security. By breeding pupfish in controlled environments and reintroducing them into the wild, these efforts aim to bolster the population and maintain genetic diversity2. Such strategies are vital for ensuring the long-term resilience of the species against ongoing environmental challenges2.

Public involvement is critical in this fight. The proposed listing and habitat designation are open for public comment until January 21, 20255. Your voice can influence the final decision, helping to secure the necessary protections for the Pecos pupfish4.

Protecting Biodiversity Benefits All

Preserving the Pecos pupfish goes beyond saving a single species. It ensures the health and stability of the entire aquatic ecosystem in the Pecos River Basin. Healthy water habitats support a diverse array of wildlife, including insects, amphibians, and waterfowl, contributing to the overall environmental balance2. By protecting the pupfish, we safeguard the intricate web of life that depends on these water resources, benefiting countless other species and future generations5.

Immediate and sustained action is essential to prevent the extinction of the Pecos pupfish. Federal protection under the ESA will provide the legal framework needed to protect critical habitats, regulate harmful activities, and implement effective recovery plans. Without these measures, the pupfish may disappear forever, resulting in an irreplaceable loss to our natural heritage1.

The Petition:

To the Director of the U.S. Fish and Wildlife Service,

We, the undersigned, urgently call upon the U.S. Fish and Wildlife Service to list the Pecos pupfish (Cyprinodon pecosensis) as an endangered species under the Endangered Species Act (ESA).

The Pecos pupfish, native to the Pecos River Basin in New Mexico and Texas, faces imminent threats from invasive species, climate change, and industrial activities such as oil and gas extraction. These factors have drastically reduced their habitat and population, pushing this resilient fish to the brink of extinction. Without immediate federal protection, the Pecos pupfish may be lost forever, leading to a significant decline in the biodiversity of our native aquatic ecosystems.

Conservation and stewardship are paramount in preserving the Pecos pupfish. Listing the species under the ESA will provide the necessary legal framework to protect its critical habitats, regulate harmful activities, and implement recovery plans. These measures are essential to halt the decline of the pupfish and promote the restoration of their natural environments.

By taking decisive action to protect the Pecos pupfish, we ensure not only the survival of this unique species but also the health and stability of our broader ecosystem. Preserving the Pecos pupfish safeguards the intricate web of life that depends on healthy water habitats, benefiting countless other species and future generations.

We urge the U.S. Fish and Wildlife Service to act now to save the Pecos pupfish and secure a sustainable and thriving future for all.

Sincerely,

To Top
