You do not need a large water feature or pond to attract wildlife. Ten years ago I bought an oak barrel, filled it with water and planted up. I did not realise but two species of native snails were brought in on the plants. One was the Great pond snail, the other the Great ramshorn snail. They have grown in numbers and there is now a small colony.
This feature is also used by the birds. A small branch placed in the appropriate place allows them to drink.
Correct planting keeps the water clear and healthy.
A nice addition to any garden.
Happy Sunday safari.
