As winter rolls in, birds fly south, mammals curl up in their burrows and amphibians prepare for a long season of hibernation. For many species, these months are crucial for survival, as they must find a safe and viable place to rest until the warmth of spring returns. As gardeners, you have a unique opportunity to play a crucial role in providing and protecting these much-needed habitats. In this article, we will explore what you can do to help these creatures in your garden and around pond areas during the winter months.
Creating a suitable habitat is the first step towards supporting amphibians during the winter. Ponds are the most common and beneficial habitats for amphibians, as they provide a water source, food and a place to breed.

While many amphibians, such as frogs and toads, are well adapted to withstand the cold, they still need places where they can seek shelter and hibernate safely. Piles of leaves, logs, and rocks are ideal as they mimic the natural environments these species use for hibernation. By leaving a wild area in your garden with these elements, you will provide a perfect sanctuary for amphibians to ride out the winter.
You can also construct a hibernaculum, which is a man-made structure that provides a place for amphibians to hibernate. Typically made from logs, soil, and leaf litter, these structures provide a secure and insulated space for hibernation.

If you have a pond in your garden, it can become a vital winter haven for many amphibian species. Planting native pond plants will help provide cover and food for hibernating amphibians. These plants are also beneficial for pond health, as they help to oxygenate the water and reduce algae growth.
You should also consider the depth of your pond. A shallow pond is likely to freeze solid in the winter, endangering any animals that have chosen it as their hibernation spot. By making sure part of your pond is at least one meter deep, you will provide a space that doesn't freeze, offering a safe environment for hibernation.
While amphibians will typically have eaten their fill before winter sets in, providing a supply of food can help those that emerge on milder winter days or those that didn’t manage to store enough energy. Leaving a small area of your garden messy will encourage insects and other invertebrates, which are a vital food source for amphibians.
Amphibians do not drink water, but they do absorb it through their skin. Providing a source of fresh water that doesn't freeze, like a bird bath with a heating element, will provide an essential resource for amphibians during the winter months.
A significant part of protecting amphibians in your garden is about reducing threats. Human activities can disturb or harm hibernating animals, so it's important to be mindful of where amphibians might be sheltering. Avoid turning compost heaps or disturbing piles of leaves or logs during the winter, as these could be home to hibernating amphibians.
Cats are a common predator of amphibians, and their presence can be distressing for these creatures. If you have a cat, consider keeping it indoors at night when amphibians are most active, or at least away from pond and garden areas where amphibians might be present.
Lastly, keeping a record of the amphibians in your garden can provide valuable information for local wildlife organisations. By recording when you see amphibians, what species they are, and where in your garden they are found, you can help to build a picture of local amphibian populations.
Monitoring your garden and pond for signs of amphibians can also alert you to any problems. Unusual behaviour or a sudden drop in numbers could indicate a disease outbreak or other issues. By acting quickly, you can help to prevent further loss and contribute to the overall conservation of amphibians.
As gardeners, you have a unique role in the protection of amphibians. By creating suitable habitats, providing food and water, reducing threats, and monitoring their presence, you can help to ensure that these fascinating creatures continue to thrive in your gardens and our wider environment, even during the harsh winter months.
Providing a robust food source for amphibians is another crucial step gardeners can take. Food plants play a vital role in the ecosystem by attracting insects and other invertebrates, which are the primary diet for many amphibians. Native plants to the UK like ivy, hawthorn, or bramble can be very beneficial due to their appeal to insects. These plants not only provide food but also excellent coverage for amphibians seeking shelter.
In addition, a compost heap is another worthwhile addition to your garden. Not only does this help with your garden's waste management, but a compost heap is also a hotspot for various insects. As such, common toads, in particular, are known to be attracted to compost heaps due to the abundance of food it offers. However, remember that compost heaps can become hibernation spots for amphibians during winter. Therefore, gardeners should avoid disturbing compost heaps to prevent harming any potential residents.
A wildlife-friendly garden caters to all forms of garden wildlife, including amphibians, reptiles, and garden birds. One of the essential aspects of a wildlife-friendly garden is diversity. A varied garden with different plants, habitats, and food sources will attract a wide range of wildlife. For example, log piles and rockeries can provide shelter for many species, including amphibians and reptiles.
Ponds are also a key feature of a wildlife-friendly garden. Even a small pond can be a valuable habitat and breeding ground for many species, from frogs and toads to garden birds and insects. A wildlife pond doesn't need to be perfectly maintained or cleaned, as a little bit of algae or pondweed can provide important cover and food for amphibians.
Moreover, reducing the use of pesticides and herbicides can significantly improve the health of your garden's wildlife. These substances can harm amphibians directly or reduce their food supply by killing off insects. Opting for natural pest control methods instead, such as encouraging the presence of amphibians, which are natural predators of many pests, can ensure a healthier ecosystem for all your garden's inhabitants.
Protecting our native amphibians is a responsibility that lies with all of us, but gardeners have a unique role to play. Through thoughtful actions such as creating suitable habitats, planting beneficial plants, reducing threats, and monitoring the health of the local amphibian population, you can help support these fascinating creatures throughout the harsh winter months and beyond.
From building hibernacula and compost heaps to implementing wildlife-friendly practices, every effort you put into protecting amphibians in your garden contributes to the overall health of your local ecosystem and the preservation of our British wildlife. Whether you're providing an oasis for common frogs or transforming lives for endangered species, remember, your garden is more than just a plot of land. It's a crucial piece of the wider landscape that helps our unique and varied wildlife to thrive.
