MARINE AND COASTAL SHIPPING ….. LESSONS LEARNED!

The International Maritime Organization’s (IMO) recently announced vessel lane changes for the approach to San Francisco Bay, the Santa Barbara Channel, and the Los Angeles and Long Beach port complex, will involve extending some shipping lanes, narrowing the width of others, and shifting the southbound lane in the Santa Barbara Channel and Channel Islands National Marine Sanctuary one nautical mile north. These routes pass through the National Oceanic and Atmospheric Administration‘s (NOOA) Cordell Bank, Gulf of the Farallones, and Channel Islands national marine sanctuaries where endangered blue, humpback, and fin whales feed and congregate.

The proposed route adjustments are a response to the high number of whale deaths from ship strikes over the past six years. Although the IMO’s goal is to adjust shipping routes along the California coast to protect whales from collisions with giant cargo ships, oil tankers, and cruise ships is laudable, the proposal doesn’t go far enough. The Great Whale Conservancy advocates moving the Channel Islands shipping lanes entirely out of critical feeding habitat by sending the ships south of the Northern Channel Islands, at least for the months of July through October. No one knows exactly why whales are so vulnerable to ship strikes.

These sentient beings, among the largest animals on the planet (blue whales being the largest), are extremely agile — which leaves scientists puzzled as to why they cannot avoid ships. It is hypothesized they become disoriented by the multiple sounds generated by engines, rudders, sonar, and hull movement from so many ships close by. There is also some evidence to suggest the high speeds of the ships make it difficult for the relatively slower-moving whales to avoid them.

There are many reasons why whales must be protected from potential ship strikes. Because of dwindling numbers and low reproductive rates, each species listed above is protected under the Endangered Species Act, the Marine Mammal Protection Act, and the National Marine Sanctuaries Act. But perhaps the most compelling reason for saving whales is the fact that they meet the conditions for being considered legal ‘persons’: they possess the largest and most complex brains on the planet; they have intricate cultures complete with different dialects; they are self-aware, autonomous, and capable of emotion. Which makes every whale death a significant tragedy.

Originally hailing from the UK, Wendy gained her Bachelor of Education in 1990, and spent 15 years teaching Physical Education in London to high school students. She moved to South Africa in 2005, beginning work as a research assistant with large carnivores, working on research projects initiated by the Endangered Wildlife Trust. Wendy’s education background has stood her in good stead as a tour guide, since she believes in an interactive approach, engaging guests in specialist carnivore research tours. In addition to her research and tours, Wendy is also the main organiser of the aptly named “BIKE4BEASTS” mountain bike race, organised annually to raise funds for the Endangered Wildlife Trust (www.bike4beast.coza) Wendy is a field worker with the Endangered Wildlife Trust’s Wildlife and Transport Programme. She recently completed her Master’s degree at Rhodes University, Grahamstown South Africa, which examined the impacts of roads on South African wildlife.
