Paddleboarding is a beautiful way to explore our coastline and can often provide unique access to remote areas that would otherwise go unseen. However, with this level of accessibility comes a responsibility to leave the areas visited as you found them.
Encountering a seal whilst out on the ocean can be an incredible experience, but if you are lucky enough to come face to face with these globally rare animals, you should proceed with caution. Seals may look cute and approachable, but these are, in fact, Britain’s largest land-breeding mammals with a bite four times stronger than that of a dog and the largest males reaching up to three metres in length. They are perfectly adapted to their marine environment, commanding the respect of even the most experienced sea users.
Whilst it may seem that seals pose a potential risk to humans, it is, in fact, humans that pose the greater threat to seals. Seals need to haul out on land to conduct vital life processes such as pupping, moulting, resting, socialising, digesting food and replenishing oxygen levels. However, when hauled out, they are incredibly vulnerable to being disturbed.
As the UK’s coastal ecotourism, recreation and leisure sectors expand - especially with recent restrictions on travelling abroad - there is increasing overlap between the spaces utilised by both seals and people. Some encounters reported to the Cornwall Seal Group Research Trust (CSGRT) that were thought to be harmless have been recorded as unintentional disturbance events that potentially had major disruptive impacts on wild seals, their behaviour and functions. Disturbance can be defined as ‘changing an animal’s behaviour to affect its health, wellbeing or survival’, and sadly this is all too common for our native seal population.
Disturbance can take many forms and is not always easy to spot. There are several behaviours to look out for whilst out on your board that signal a seal is aware of your presence and is at risk of being disturbed:
Suppose you spot any of these behavioural reactions, slowly and quietly back away to avoid increasing the chances of disturbing them further. Allow them the space they need within their habitat.
Some seals will show signs of habituation, whereby they have become used to the presence of people and do not demonstrate a natural, cautionary response to their presence. However, this does not mean that they are immune to the impacts of disturbance. Some seals will not react to a single paddle boarder, but after their third or fourth encounter, they will start to show signs that they are not fully relaxed. This is known as sensitisation, where the seal responds to repeated activity rather than a single event.
Which seals are worst affected?
The effects of disturbance are often invisible but are always a waste of energy for seals. Some of the physiological impacts of disturbance include increased stress and cortisol levels, a rapid heartbeat, increased breathing rate, cold water shock, cracked ribs, damaged and ripped out claws, open wounds, and long-term impacts on unborn and new-born pups as well as moulted pups who are still teaching themselves to hunt.
