Costa Rica's Court Ruling Aims to Protect Howler Monkeys from Power Line Electrocution

The Lead: Costa Rica's Legal Victory for Wildlife

In a landmark decision, Costa Rica's constitutional court has ruled that the state-owned electricity company and the Ministry of Environment and Energy must take immediate action to protect howler monkeys from electrocution on uninsulated power lines. The ruling comes after years of increasing incidents linked to development in popular tourist areas and follows a nationwide campaign by conservation organizations.

The Event Details: Court Mandates Power Line Safety Measures

The court ruled in January that the Costa Rican Electricity Institute (ICE) and MINAE had failed to implement effective measures to reduce and prevent wildlife electrocution, primarily affecting howler monkeys in the Nosara district. The government entities were given six months to implement necessary corrections to the bare wiring in power lines constructed in the area.

This legal action followed the campaign "This Is NOT Pura Vida" launched by 20 conservation organizations and rescue centers, including International Animal Rescue Costa Rica (IARCR). The campaign called for urgent government action to address what has become a growing crisis for wildlife in the region.

The Data Analysis: Alarming Electrocution Statistics

The scale of the problem is significant. In 2025 alone, IARCR reported 108 electrocuted animals, with howler monkeys accounting for up to 90% of incidents. Francisco Sánchez, a veterinarian at IARCR, has observed a rise in cases over the past decade, attributing it to increased development in the area which has become popular with tourists and immigrants from the US and Europe.

Nationwide, electric shock is one of the biggest causes of death among wildlife in Costa Rica—the only country thought to regularly log wildlife electrocution numbers. Between June 2022 and June 2023 alone, there were 6,262 documented cases of wildlife electrocution.

The Impact Analysis: Changing Development and Wildlife Coexistence

The court ruling could have major ramifications for wildlife protection nationwide. Gavin Bruce, chief executive of International Animal Rescue, emphasizes that while the case was built on data from the Nosara area, the problem extends throughout Costa Rica.

Development in previously undisturbed forest areas has exacerbated the problem. "Now, we have new areas [of electrocutions] appearing that we didn't have in the past," says Sánchez. "This is because of the development of houses, restaurants and hotels. We are rescuing from further inside the forest."

The Prediction: Global Implications and Future Protection

Although this case is specific to Costa Rica, the issue represents a global challenge for wildlife conservation. Justo Martín Martín, an environmental consultant specializing in the issue for the International Union for Conservation of Nature (IUCN), notes that while systematic studies are limited, evidence suggests the problem is global.

Conservation groups will now monitor the implementation of the court ruling and consider how to scale these protections across the entire country. "We hope it will force Costa Rica's electricity providers to finally do what needs to be done to keep wildlife safe," says Bruce. The success of this approach could serve as a model for other countries facing similar challenges in balancing development and wildlife protection.
