Teno-Rasca Marine Conservation Zone Faces Threat from Unregulated Tourism

The Teno-Rasca Marine Conservation Zone, renowned for being home to Europe’s first official whale sanctuary, is currently grappling with escalating pressures stemming from unregulated tourist activities. This situation poses a significant threat to the delicate marine ecosystem that thrives within this protected area.

Impact on Marine Life

Situated off the bustling south-west coast of Tenerife, the Teno-Rasca Marine Conservation Zone spans an impressive 70,000 hectares and was designated as a conservation area in 2011. This vital habitat is not only a sanctuary for over 300 resident pilot whales but also supports up to 20 other species of cetaceans, alongside various threatened marine turtles. The ecological significance of this area cannot be overstated, as it plays a crucial role in the preservation of marine biodiversity.

Despite the establishment of strict regulations intended to protect these marine creatures—such as prohibitions against swimming with whales and dolphins, chasing or feeding them, and limitations on the number of boats allowed near pods—the enforcement of these rules remains alarmingly inadequate. As a result, significant disturbances to marine life have become increasingly common.

Reports from conservation groups indicate that jet skis, speedboats, and unauthorized excursions frequently approach marine wildlife at dangerously high speeds. Such reckless behavior has led to numerous collisions, heightened stress levels, and alterations in the animals’ natural behaviors. A local researcher has raised concerns about the chronic stress experienced by these animals, while marine turtles face the threat of collision, and whales are reportedly changing their natural behaviors to evade disturbances. The underwater noise generated by these vessels further disrupts the communication and resting patterns of these sensitive species.

Challenges for Licensed Operators

For many licensed local operators, whale and dolphin watching represents a crucial source of income. However, these legitimate businesses are increasingly facing unfair competition from illegal operators who offer kayak and snorkeling trips with dolphins and turtles for as little as €40. While licensed operators are required to display a “Blue Boat” flag to signify their compliance with regulations, authorities acknowledge that inspections and sanctions against illegal operators are sporadic at best.

In an effort to mitigate the damage caused by unregulated tourism, Spain’s Ministry for Ecological Transition imposed a moratorium on new licenses for whale-watching boats in 2023. However, experts argue that this measure is insufficient without a robust system for monitoring private recreational craft. The surveillance vessel Mar Canario, which was purchased in 2019 specifically to patrol conservation areas, has reportedly been absent during the peak tourist summer months, further exacerbating the challenges faced by licensed operators.

Anthropologists and marine biologists from the University of La Laguna have pointed out that the lack of coordination between various administrative bodies and the limited enforcement of existing regulations represent the greatest weaknesses in the sanctuary’s management. They emphasize that while education for tourists and businesses is essential for fostering awareness, it cannot replace the need for effective regulation and consistent surveillance to ensure the protection of this fragile ecosystem.

For visitors to Tenerife, the message is clear: the whale sanctuary is not only unique but also incredibly fragile, deserving of protection and respect. It is imperative for tourists to adhere to the established rules when booking excursions or utilizing watercraft, as this is vital for ensuring that future generations can continue to experience and appreciate these extraordinary marine animals in their natural habitat.

Key Points

• The Teno-Rasca Marine Conservation Zone is under threat from unregulated tourism.
• It is home to over 300 pilot whales and various endangered species.
• Strict rules exist but enforcement is limited, leading to disturbances in marine life.
• Illegal businesses compete with licensed operators, undermining conservation efforts.
• A moratorium on new whale-watching licenses was imposed in 2023, but experts call for stronger monitoring.
• Education and effective regulation are essential for the sanctuary’s protection.
