Nonprofit Begs Sharpshooters to Kill More Than 2,000 Invasive Deer on Catalina Island in California

By: Georgia | Last updated: Nov 21, 2023

Catalina Island, a tranquil oasis off the coast of Southern California, is currently facing a pressing ecological issue. The island, known for its pristine beauty, is experiencing an ecological imbalance due to over 2,000 invasive mule deer. 

Introduced in the late 1920s, these animals are now threatening the island’s delicate ecosystem, leading the Catalina Island Conservancy to seek urgent and effective solutions to mitigate the escalating problem.

The Unwanted Guests

The mule deer, although a part of the island’s fauna for almost a century, have become an invasive species, competing for the limited vegetation. According to Whitney Latorre, the chief executive of the Catalina Island Conservancy, both the island and deer are striving for survival.

The semi-arid land of Catalina is under threat, with its vegetation rapidly depleting due to the overwhelming deer population.

A Controversial Solution

The Conservancy has proposed a bold measure to control the deer population – employing sharpshooters in helicopters to cull the animals. This method has historical precedence; in 1990, around 1,700 goats were eradicated in a similar manner to preserve the island’s ecosystem.

While controversial, such drastic actions are considered necessary by some to ensure the survival and thriving of native species and habitats.

Community Response

Dianne Stone of the Catalina Island Humane Society has voiced concerns about the proposed culling. The mule deer, despite being invasive, have been a part of the island’s ecosystem for decades.

Stone and others believe in the animals’ intrinsic value to the island’s natural appeal. A petition against the mass culling has garnered over 3,200 signatures, reflecting a significant opposition to the Conservancy’s plan.

Ecological Concerns

The conservation challenge is amplified by the ongoing climate crisis. “Unless we address the deer issue, the island will become more and more vulnerable to devastating consequences brought on by rising temperatures and drought,” Latorre emphasized.

The increasing vulnerability of the island necessitates immediate action, with the mule deer’s rapid consumption of vegetation accelerating environmental degradation.

Alternative Solutions

A non-lethal approach, similar to the birth control methods used to manage the bison population on the island, is being advocated by some groups. Dianne Stone questions the morality of killing the deer, proposing porcine zona pellucida immunocontraception as an alternative.

This divide in approaches towards population control illustrates the complex and multifaceted nature of the issue at hand.

Ethical Questions

The proposal of employing sharpshooters raises ethical questions. The considered “gruesome and violent” method is facing backlash from residents and animal welfare advocates.

The Conservancy, however, views this as a potentially effective and immediate solution to curtail the rapid deterioration of the island’s ecosystem. This clash of perspectives underscores the complexity of balancing ecological preservation and ethical considerations.

Historical Interventions

In the past, similar measures were taken to control invasive species on Catalina Island. The elimination of goats and pigs through hunting expeditions proved to be effective in restoring the ecosystem’s balance.

Such historical actions are now part of the ongoing debate, as stakeholders weigh the potential benefits and ethical implications of another mass culling initiative.
