Why Marine Mammal Rescue Matters

Impact on Individual Animals

Rescuing and responding to marine animals is no small task. Marine mammals strand for a number of reasons: disease, starvation, entanglement in debris or fishing gear, vessel interactions, shark interactions, harassment by beachgoers, and maternal abandonment, just to name a few. Providing direct support and medical treatment to these animals in distress can be life-saving.

Broader Ecosystem Benefits

In the long term, strandings provide information that would be otherwise impossible to collect. Data and samples collected during strandings allow scientists to monitor the health of our oceans - through identification of harmful algal blooms, contaminants, prey availability, etc. This information is crucial for maintaining ecosystem balance and ensuring the health of marine environments.

Human Responsibility

As a marine mammal biologist, I have worked worldwide with marine mammal rescue and rehabilitation programs. These experiences have allowed me to witness numerous stranded or entangled marine mammals, most of which are intricately linked to direct or indirect human impacts on our oceans. It's our responsibility to mitigate these impacts and support rescue efforts. Volunteering, donations, and advocacy are just a few ways we can all contribute.

Common Reasons Marine Mammals Need Help

Entanglement in Fishing Gear

Marine mammals often get entangled in fishing gear, which can lead to severe injuries or even death. This is a significant issue as it not only affects the individual animal but can also have broader implications for the species. Entanglement is one of the most common reasons marine mammals need rescuing.

Disease and Starvation

Marine mammals are susceptible to various diseases and can suffer from starvation due to changes in their environment or food availability. Pollution and environmental changes can exacerbate these issues, making it difficult for these animals to find enough food or stay healthy. Pollution is a key factor contributing to these problems.

Human Interactions

Human activities, such as vessel strikes, harassment by beachgoers, and habitat destruction, can severely impact marine mammals. These interactions often result in injuries or stress that require intervention and rehabilitation. It's our responsibility to minimize these negative impacts and help these animals recover.

The Rescue Process: From Call to Release

Initial Response

When a call comes in about a stranded marine mammal, the rescue team springs into action. Similar to EMTs for humans, they head to the beach to perform physical examinations on the stranded animals. They measure vitals like temperature, heart rate, and respiratory rate, take blood samples, and treat minor injuries or ailments such as dehydration. Each day can be completely different from the next, making this work both challenging and rewarding.

Medical Treatment

If the initial assessment shows that the animal needs more extensive care, it is transported to a rehabilitation center. Here, the animal receives specialized medical treatment tailored to its specific needs. This can include anything from surgery to treat injuries to long-term care for chronic conditions. The goal is always to stabilize the animal and prepare it for eventual release back into the wild.

Rehabilitation and Release

Once the animal is stable, the focus shifts to rehabilitation. This involves a combination of medical care, physical therapy, and sometimes even training to ensure the animal can survive on its own. The ultimate goal is to release the animal back into its natural habitat as soon as it is ready. Whether treated on the beach or taken to a rehabilitation center, the aim is always the same: to give these marine mammals a second chance at life.

Challenges Faced by Rescue Teams

Unpredictable Nature of Strandings

Rescue teams never know what to expect when they head out for a call. Each day can be completely different from the next. Some days, the team might be monitoring a seal on the beach, while other days, they could be collecting information from a deceased dolphin. This unpredictability makes it challenging to allocate resources and plan effectively.

Resource Limitations

Rescuing and responding to marine animals is no small task. Teams often face significant resource limitations, including funding, equipment, and personnel. Support our marine animal rescue and response team by making a donation or volunteering your time. Every bit helps in ensuring these animals get the care they need.

Environmental Hazards

The marine environment itself poses numerous hazards. From rough seas to extreme weather conditions, rescue teams must navigate these dangers to reach and treat stranded animals. Additionally, environmental factors like pollution and debris can complicate rescue efforts, making it even more critical to address these issues for the long-term health of marine ecosystems.

Success Stories: Marine Mammals Given a Second Chance

Whale rescues are some of the most dramatic and challenging operations undertaken by marine mammal rescue teams. These gentle giants often find themselves stranded or entangled in fishing gear, requiring immediate and expert intervention. One notable success story involves a humpback whale that was disentangled from a massive fishing net off the coast of California. After hours of meticulous work, the rescue team managed to free the whale, which swam away with minimal injuries.

Seals are frequently found stranded or injured along coastlines, often due to human activities or environmental hazards. Rehabilitation centers play a crucial role in nursing these animals back to health. For instance, six harbor seals that were rehabilitated and released had similar movements and behaviors to wild seals, indicating successful reintegration into their natural habitat. Rehabilitation not only saves individual seals but also contributes to the overall health of seal populations.

Dolphins, known for their intelligence and social nature, are also common candidates for rescue and rehabilitation. A review of 56 case studies found that approximately one-third of rehabilitated common bottlenose dolphins survived for at least six weeks post-release, exhibiting normal behavior. This is a significant achievement, as it demonstrates that rescued dolphins can successfully adapt back to their wild environment. The efforts of rescue teams ensure that these amazing creatures get a second chance at life.

The Role of Research in Rescue Efforts

Health Monitoring

Research plays a crucial role in monitoring the health of marine mammals. By taking blood samples and measuring vitals like temperature, heart rate, and respiratory rate, rescue teams can assess the immediate needs of stranded animals. This data helps in diagnosing illnesses and determining the best course of treatment. Regular health monitoring also provides insights into the overall well-being of marine mammal populations.

Data Collection

Collecting data is essential for understanding the causes behind marine mammal strandings and injuries. Teams often take pictures, conduct necropsies on deceased animals, and record various health metrics. This information is invaluable for identifying patterns and potential threats to marine life. Detailed data collection enables researchers to make informed decisions and improve rescue strategies.

Informing Conservation Strategies

The data gathered from rescue efforts doesn't just help individual animals; it informs broader conservation strategies. By understanding the health and challenges faced by marine mammals, researchers can advocate for better protection measures. This might include policy changes, habitat preservation, or public awareness campaigns. The ultimate goal is to create a safer environment for marine life, ensuring their long-term survival.

Collaborating for Conservation

Working with other nonprofits and local communities is essential to support wildlife health and public involvement. These partnerships can amplify efforts, share resources, and create a more significant impact. Collaboration is key to tackling the complex issues marine mammals face.

Educating the public to reduce human-wildlife conflict is crucial for promoting healthy marine wildlife and human communities. Community involvement can take many forms, from participating in beach clean-ups to attending educational workshops. When communities are engaged, they become powerful allies in conservation efforts.

Data can also be used to help the government make management decisions that result in long-term conservation of a species. A great example of this is the documentation of North Atlantic right whale mortalities caused by vessel strikes in the early 2000s. This led to the alteration of shipping channels and implementation of vessel speed restrictions to mitigate their interactions. Government support is vital for enacting policies that protect marine life.

Long-Term Impact of Rescue and Rehabilitation

Survival Rates Post-Release

One of the most critical measures of success for marine mammal rescue and rehabilitation is the survival rate of animals post-release. For instance, a study found that 52% of rehabilitated monk seal young survived for at least one year after being released back into the wild. This statistic highlights the potential for rescued animals to thrive once returned to their natural habitats.

Population Health

Rehabilitation efforts can also have a positive impact on the overall health of marine mammal populations. For rare species, releasing rehabilitated individuals can help augment wild populations. This is particularly important for species that are already at risk of extinction. The success of these programs, however, can be challenging to measure without long-term survival data.
