Gardens for Wildlife
Start with as many native species as you can, the more you include the more niche habitats you can create and the wider the variety of wildlife you will attract. Invertebrates need warm sheltered sites (hedges, shrubs, trees). First look for some locations that are in the sunshine and away from the wind and plant some trees or shrubs in these areas. You will find that many of our native trees and shrubs also flower and fruit, and some of the more important to include are birch, hazel, ivy, bramble, elder, blackthorn & dog rose (these will also attract birds and small mammals to the fruit and nuts).

Plant lots of the old cottage garden favourites, the bi-annuals and perennials that throw up beautiful flowers full of nectar, attracting insects and their larvae, that in turn attract small mammals and birds (these will also eat seeds later in the season). Start with evening primrose,

Trees
Trees play a vital role on a global scale. They are the lungs of the earth, they control our weather patterns, create soil, stabilise erosion, act as coolers and lock up vast amounts of carbon (the greenhouse gas). If they are crucial to our survival, they are absolutely critical to wildlife. Native tree species can play host to 400 species of herbivorous invertebrates, which in turn will attract higher species to feed on them. Compare that to a non-native horse chestnut that plays host to just 4! This is why (space permitting) native trees are number one on the wildlife designer’s list.

The sheer scale of a large native tree is part of the secret. Just consider that a mature tree base may occupy a square meter of your garden. But when you add the surface area of trunk, boughs and leaf cover, you may have added a 500 square meters to your garden. Full of niche habitats at every level, it provides places to breed (birds nests, burrowing beetles or spiders webs amongst the leaves), food

Climbers
Climbing plants provide some of the benefits of trees but generally take up less space, can be trained and often have the additional benefit of growing up fences and walls. Climbers typically provide shelter for invertebrates, nesting and roosting sites for birds, and often provide flowers for nectar and fruit for food. Well-chosen climbers also add colour and form to a garden and can be as decorative as they are useful to wildlife. 

Herbaceous Plants 
Flowers, particularly the old-fashioned single-flowers and annuals are stuffed with pollen and nectar. These plants will attract huge numbers of invertebrates, including hover flies, bees and butterflies. And in the flower border you can keep removing the dead heads to extend the flowering season well into the autumn.
The key is to provide year-round food sources, so choose plants that will flower at different times of year, especially during early spring and the late summer. To help in these seasons you can include a few non-native species like aubrietia and buddleia, commonly known as the butterfly bush. While many of the listed plants add colour and shape to please the eye, it is also important to include less popular plants such as nettles if you really want to boost the butterfly and wildlife population because many species use plants as nursery and feeding beds. 

aubrietia, bladder campion, nicotiana, golden rod, foxglove and snap dragon. Also add fragrant herbaceous plants such as marjoram, lemon balm, mint and sage. Undisturbed places are also a requirement and plenty of them. Add log piles in dark corners, stone and rock piles in the sunshine, uncut grass and ivy clad trees and walls. All of these will provide shelter, night roosts and breeding grounds for all types of invertebrates, birds and animals.
A garden pond or a regular source of water is critical to the success and survival of the wildlife garden. Not only for the huge diversity of creatures that will become resident in it (skaters and diving beetles) and the creatures that require water to breed (frogs, newts and dragonflies) but also for the general population that will use it to bathe, drink and feed (bats, birds and mammals). To see the value of a wildlife pond for yourself, simply sit quietly near an established pond on a late spring evening and let all the wildlife parade before you, its fabulous!

(leaves, fruit, nuts, dead wood, leaf litter), shelter or sunshine (hollow boughs, birds perches, leaves and bark). In one square meter of garden you can create hundreds microclimates (niches) exactly the variety you are trying to achieve.If space permits you probably already have a tree (even a miniature) in your garden. But if you can, now you know the full value and potential of trees, plant another one! There is no better choice of all kinds of wildlife.

compaction allows birds access to probe below its surface. 
If you have the opportunity to plant a wildflower meadow, or you can allow your lawn to ‘run wild’ for part of the season, will provide another great wildlife ‘niche’, and with the right grass species and flowers, it will also look very attractive.
