By simply leaving things a bit messy you can provide a home to all kinds of wildlife:
Seed Heads
Leaving the seed heads of plants such as wild carrot provides essential food and shelter for birds and insects.
Leave the leaves
By simply allowing leaves, twigs and sticks to pile up yo can provide a cosy home for hedgehogs and dormice to hibernate.
Just add water
It's important to supply wildlife with water over the colder months, especially in freezing temperatures.
Berries
Avoid pruning berry or fruit-bearing bushes or trees as these provide indispensable food for birds over the colder months.
Provide Shelter
From bird boxes to bug hotels creating habitats can provide warm and safe space for wildlife.
Log Piles
Another way to create shelter is to make a log pile. Providing an habitat for all kinds of plants, animals and fungi.
