From microscopic organisms and tadpoles to dragonflies and frogs, every species contributes to a thriving freshwater habitat. By taking a moment to pause and look closely, visitors can discover an extraordinary diversity of wildlife living within these seemingly quiet waters.

Whether you're searching for frogspawn in spring, watching dragonflies in summer, or simply enjoying the peaceful surroundings, the ponds of Balloch Castle Country Park offer an ever-changing window into the natural world.

Hedgehogs are most active after dusk, emerging from their daytime shelters to forage for food amongst woodland edges, grasslands and areas of dense vegetation. Their diet consists mainly of insects, beetles, caterpillars, earthworms and other invertebrates, making them an important part of the park's natural ecosystem.

The variety of habitats found throughout Balloch Castle Country Park provides ideal conditions for hedgehogs. Woodland margins, hedgerows, wildflower areas and leaf-litter-rich environments offer valuable shelter, nesting sites and feeding opportunities. These connected green spaces allow hedgehogs to move safely through the landscape as they search for food and mates.

During the spring and summer months, female hedgehogs raise their young, known as hoglets, in carefully constructed nests hidden amongst dense vegetation. As autumn approaches, hedgehogs begin preparing for winter by building hibernation nests from leaves, grass and other natural materials. They then enter a period of hibernation until warmer temperatures return in spring.

Although they are rarely seen during daylight hours, signs of hedgehog activity can often be found throughout the park. Their presence is a positive indicator of healthy habitats and a thriving invertebrate population. The continued sightings recorded by Park Rangers highlight the importance of maintaining wildlife-friendly spaces where native species can flourish.

For visitors, the knowledge that hedgehogs are living within the park adds another layer of interest to an evening walk or wildlife adventure. While encounters are often brief and special, these charming mammals remain an important part of the rich biodiversity that makes Balloch Castle Country Park such a valuable place for nature.

One of the most familiar sights on the water is the swan, often seen gliding across the loch or nesting in sheltered bays and along the shoreline. A variety of duck species also make use of the loch, including Mallards, Tufted Ducks, Mandarin Ducks and Goldeneye. During the winter months, Loch Lomond becomes particularly important for visiting waterbirds, providing feeding and resting areas for species escaping harsher conditions elsewhere. These seasonal visitors contribute to the loch's reputation as one of Scotland's most significant freshwater habitats for birdlife.

The loch also supports a range of specialist waterbirds. Great Crested Grebes can often be seen diving beneath the surface in search of fish, while Goosanders use their slender, serrated bills to catch prey underwater. Grey Herons are regular visitors to the shoreline, standing motionless in shallow water before striking with remarkable speed. Cormorants are another familiar sight, often seen perched along the water's edge with their wings spread to dry after fishing.

Beneath the surface lives one of Loch Lomond's most distinctive species – the Powan. This rare freshwater fish is found in only a handful of Scottish lochs and is particularly associated with the deep waters of Loch Lomond. Considered a relic of the last Ice Age, the powan is an important part of the loch's unique biodiversity and contributes to its national conservation significance.

The loch's margins and shallow waters are equally important. Reeds, aquatic plants and wetland vegetation provide shelter for countless insects, amphibians and young fish, creating valuable nursery habitats that support the wider ecosystem. These productive waters attract a diverse range of wildlife and help maintain the delicate balance of life within the loch.

The variety of species found in and around Loch Lomond reflects the health and importance of this internationally recognised freshwater environment.

For visitors to Balloch Castle Country Park, spotting a red squirrel can be a memorable wildlife experience. Whether glimpsed darting through the canopy or quietly feeding amongst the trees, these distinctive mammals add colour, character and a sense of wildness to the park's woodland landscapes.

The presence of Red Squirrels highlights the importance of maintaining healthy woodlands and diverse habitats within the park, helping to support a wide range of wildlife and preserve the natural beauty of this special place on the shores of Loch Lomond.

Several species of bat are known to use the wider Loch Lomond area, and the Park’s varied habitats provide excellent feeding opportunities. Woodland margins, mature trees, hedgerows and sheltered waterways all attract a wide range of flying insects, which form the main food source for bats. Common and Soprano Pipistrelle bats, Daubentons and Brown Long-eared bats are found in the Park and be observed weaving through woodland and around parkland features, sometimes appearing as small, fast-moving silhouettes against the evening sky.

Bats use echolocation to navigate and hunt in the dark, emitting high-frequency sounds that allow them to detect obstacles and prey with remarkable precision.

Daytime roosts are typically found in tree cavities, loose bark, buildings and other sheltered structures. The mature trees and varied landscape of Balloch Castle Country Park provide potential roosting opportunities, while the surrounding environment offers rich feeding grounds throughout the warmer months.

Bats are protected in the UK and are recognised as important indicators of a healthy environment. Their presence reflects a strong insect population and a well-connected network of habitats that support wildlife across the landscape.

For visitors, early evening walks through the park can offer the chance to see bats in action as they begin their nightly hunt. Whether flickering through woodland clearings or sweeping low over the water, these elusive mammals add a fascinating dimension to the park’s rich and varied wildlife.

Birds of Prey are typically seen soaring slowly, scanning the ground below for signs of movement. Their diet is varied and opportunistic, with small mammals forming an important part of what they eat. From perches in trees or while gliding overhead, buzzards help to maintain a natural balance within the park’s ecosystems.

The park’s varied habitats provide excellent conditions for both predators and their prey. Woodland edges, rough grassland, hedgerows and quieter undisturbed areas all support a range of small mammals that live largely out of sight of visitors. These include species such as field mice, voles and shrews, which play a vital role in the food chain as both seed dispersers, insect controllers and a key food source for birds of prey and other predators.

Small mammals are most active at dawn, dusk and during the night, making them rarely seen but constantly present within the ecosystem. Their tunnels, burrows and feeding sites help aerate soil and support plant growth, demonstrating their importance far beyond their size.

The presence of Birds of Prey over the park is a sign of a healthy, functioning environment, where natural processes continue to shape wildlife populations. Their soaring flight and distinctive calls are now a familiar feature of the skies above Balloch Castle Country Park.

Together, birds of prey and small mammals represent the balance of life within the park—hidden activity beneath the grass and leaves, and wide-ranging movement above the treetops. For visitors, a quiet moment outdoors may reveal both the subtle signs of small mammal life and the sweeping presence of one of Scotland’s birds of prey.

The “Who Lives Here?” project is an invitation to explore this living landscape more closely. It brings together some of the wildlife that makes the park so special, helping visitors discover the animals that share this space and the habitats they depend on. Whether it’s birds in the treetops, mammals moving through the undergrowth, insects among wildflowers or fish beneath the surface of the loch, every species plays a role in shaping the park’s natural environment.

Some of these creatures are easy to spot during a walk, while others are more elusive and reveal themselves only through patient observation or subtle signs. Together, they form a complex and interconnected ecosystem that changes with the seasons and responds to the rhythms of nature.

This project aims to help visitors notice more of what is already around them. A rustle in the leaves, a flash of movement at the water’s edge, or a call from the canopy can all be signs of the rich wildlife that calls the park home. By learning more about these species, visitors can deepen their connection to the landscape and better understand the importance of protecting it.
