Celebrating World Otter Day with the Cardiff Stand for Nature Youth Group

Luke Massey

Our Stand for Nature forum member Lauren writes about this iconic river species, and how we are working with partners to highlight the importance of a healthy river system here in Cardiff.

World Otter Day is a perfect opportunity to shine a spotlight on these fascinating creatures and the vital role they play in our ecosystems. At The Wildlife Trust of South and West Wales, the Stand for Nature Youth Group is passionate about otter conservation and the health of our local rivers. By engaging in various projects and campaigns, we strive to protect river wildlife and ensure the cleanliness and biodiversity of our waterways. Our commitment is demonstrated through our work with the Cardiff Otter Project as part of the Save Our Taff campaign, which plays an integral part in our efforts to foster a sustainable and thriving environment for otters and other wildlife.

How River Pollution Affects Otter Populations

It is no surprise that freshwater pollution can degrade the quality of otter habitats. Pollutants can reduce the availability of clean water and suitable prey, making it harder for otters to find the food and shelter they need to survive. Pollution can also lead to the destruction of aquatic vegetation and other important habitat features that otters rely on for hunting and denning.

Through our research and conservation efforts within the Save Our Taff campaign, we aim to mitigate these impacts by advocating for cleaner rivers and healthier ecosystems. By addressing pollution sources and promoting biodiversity, we can help ensure that otters continue to thrive in the River Taff and beyond.

Working with Cardiff University Otter Project

For the Save Our Taff campaign, our dedication to otter awareness stems from our active involvement in the Cardiff University (CU) Otter Project. Laura, who is one of the placement students working on the CU Otter project, said:

“The Cardiff University Otter Project is a research group using otters as sentinels for chemical contamination of the environment and studying the genetics / genomics, health and behaviour of the Eurasian otter. We run a national scheme collecting otters found dead in England, Scotland and Wales for post-mortem examination and environmental surveillance and have been running for 30 years.

As Eurasian otters live at the top of the aquatic food chain, the otter is a key indicator of the health of aquatic systems. For example, in the 1950s-70s otter populations declined dramatically and disappeared from many parts of the UK completely. This was thought to be due to the use of persistent, bioaccumulative and toxic chemicals (PBTs).

Populations began to recover once legislation was put in place to restrict or ban the use of PBTs in addition to other conservation legislation and improvements on water quality. This is one of the ways that otters can demonstrate a clean and healthy ecosystem.

As a diurnal, solitary, and elusive species, population estimates and presence of otters can be quite hard to gauge. Spraint and track surveys, such as those that the Save Our Taff group have been assisting our project with, can give us valuable information on population distributions and are a fantastic indirect method of otter monitoring.”

The Stand for Nature forum has been helping the CU Otter project with these vital surveys, helping to identify field signs such as  footprints, scratches, droppings (spraints), and slides into the river. These indicators are crucial for understanding where otters are thriving and where they might need more protection.

As Laura has suggested, an important aspect of their work is seeing how river quality impacts the survival of this important river predator. By monitoring otter populations and their health, they can assess whether impacts on otter population levels stem from river pollution.

This research is essential for understanding how pollution affects river biodiversity and strengthens our advocacy for cleaner rivers. Participating with the Otter Project and their otter surveys has allowed us to gain a greater understanding of the river Taff as a natural habitat for essential river creatures. Adding weight to our arguments against river pollution, and for protecting our biodiverse rivers.

How the Save Our Taff Campaign is Highlighting Our River Wildlife

Our Save Our Taff campaign is a pivotal part of our mission to protect and preserve the river’s wildlife, including otters. We believe that clean and biodiverse rivers are essential not only for wildlife but also for people. Healthy rivers support a wide range of species, including otters, fish, and birds, and provide recreational and aesthetic value for local communities. By promoting the importance of clean rivers, we advocate for a healthier environment for everyone and future generations.

One of the main objectives of the Save Our Taff campaign is to identify key areas of pollution along the River Taff. By pinpointing these areas, we can focus our conservation efforts where they are most needed and work towards reducing pollution sources. Also, by spreading awareness about our campaign and connecting with community groups to we have had the opportunity to discuss avenues of analysing river pollution levels at certain areas along the River Taff. This community-driven approach fosters a sense of ownership and responsibility towards maintaining a clean and healthy river ecosystem. Public participation and involvement at any level is essential for successful environmental protection and progress.

The Importance of Protecting Otters Along the River Taff

Protecting otters along the River Taff is crucial for several reasons. Otters are top predators and key indicators of river health, meaning their presence signifies a thriving ecosystem. Their conservation helps maintain the ecological balance, as they control fish populations and contribute to the diversity of the river environment. In Cardiff, the River Taff is a significant natural resource that supports a wide array of wildlife and provides recreational opportunities for the community. By safeguarding otters and their habitat, we ensure the river remains a vibrant and healthy ecosystem, benefiting both wildlife and people.

On this World Otter Day, we celebrate the resilience and beauty of otters while reaffirming our commitment to their conservation. Through the Cardiff Otter Project and the Save Our Taff campaign, we work tirelessly to ensure that otters continue to thrive in a clean and vibrant River Taff. Join us in our efforts to protect these wonderful creatures and their habitat!
