Do you garden for wildlife? If so, what type of wildlife are you aiming to attract? Let me take a guess…
If you’re like most wildlife gardeners, you’ll be feeding the birds and hedgehogs and providing the birds with food, water, nest boxes and roosting pockets, and perhaps growing things like Teasels and Pyracantha for the seeds and berries. You’ll be growing pollinator-friendly flowers and putting up bee houses, and looking for the little round cut-outs on your rose leaves made by leaf-cutter bees. Hedgehogs will benefit from des res hibernation houses, holes cut into fences for access, and from being fed. You’ll be delighted to see foxes on your patio, and you’ll perhaps be throwing them scraps of food, or even whole raw chicken wings. A dedicated wildlife guardian might even feed them jam sandwiches laced with mange treatments. All this is a huge step in the right direction, but here’s the question: do you also leave greenfly alone, and allow slugs & snails to go about their business without poisoning them?
Maybe you’re more like me. I garden for invertebrates and positively welcome the arrival of aphids in the spring, because I know that without aphids, a whole host of miniature life might well starve or fail to find a way to raise their next generation and Blue Tits could struggle to raise their broods.
If you’re like me, you’ll know that invertebrates, from microscopic soil creatures to slugs and snails are, in partnership with native plants, pretty much the builders, keepers and recyclers of all the earth’s ecosystems. Without them, there’d be no soil, no crops, and no higher animals at all, so it’s very worrying that we are losing our insect biomass hand over fist right now. Climate change? That’s only partly to blame.
The problem feels so vast that we feel helpless, and yet we can all of us do something to help. Small actions do very much add up to big gains here because so many invertebrates really don’t need huge amounts of territory.
Take a look at the average garden. Firstly, the chances are that there’ll be a lawn, and that lawn will be pretty well manicured to present a nice, flat, green appearance, and there’s absolutely nothing wrong with that, as long as we don’t use chemicals to keep it that way, and as long as it’s balanced with other features, because some invertebrates and wildflowers positively thrive in very short grass: ground-nesting bees, for instance, and Self-Heal.
Secondly, an increasing number of gardens have large, paved areas and nothing much else, or they have artificial grass instead of a lawn, and without soft landscaping in the form of living plants, these gardens have nothing much to offer our wildlife. To our small scurrying, creeping, crawling friends, they are barren and inhospitable, and what’s more, they are often regularly dosed with toxic chemicals to keep weeds, ants and algae away.
And thirdly, an awful lot of gardens have no trees. It’s hard to overestimate the importance of trees to our native wildlife. They provide leaves as food for caterpillars and leaf-miners and leaf beetles, and when the leaves drop they provide the raw material from which humus will be made by earthworms and other dead-leaf-eaters, and they are a ‘duvet’ for overwintering invertebrates. Trees provide nectar for pollinators, bark and crevices for invertebrates, shade, shelter and nesting opportunities for so many different animals. Some provide more than others, of course: fruit trees provide food for pollinators, fruit eaters and detrivores, and – for instance – did you know that an Oak tree supports more wildlife than any other tree? An astonishing 500 different species of animals, butterflies, moths, insects and other invertebrates use oak trees to feed, breed and roost, and some of the specialist species rely solely on the Oak to survive. Other trees might have less impressive lists, but they all support invertebrates which birds and other animals come to feed on and space to rest and nest, and it’s important to note that if you have a bird feeder, birds will be much happier to use it if they have a tree to hide in while they check that the coast is clear before coming to feed. Most modern garden could not accommodate an Oak, but even a small tree like a fruit tree or a Rowan is honestly very useful – and these days it’s well worth thinking about the fact that they can reduce the ambient temperature in their shade area by several degrees.
As trees age, they become more and more useful, and when they get so old that bits start falling off, or the whole tree ends up on the ground, they continue to be useful – nay, essential – to some species as the decomposers arrive and eat their way through the dead wood. Forms of life from the tiniest springtail to sizeable fungi* and the larger animals all arrive to eat them and to use the dead wood to shelter under, or as a larder (woodpeckers, for instance, love a fallen tree).
A good way to understand the interconnectedness of our ecosystems is to take one example and follow it through. The dead wood lies on the ground, gets damp, and is soon populated by springtails (one of our smallest visible creatures). Those springtails eat the rotting wood, and are in turn eaten by, for example, a predatory beetle. The beetle (if he’s unlucky) is eaten by a mouse, and the mouse is caught and swallowed by an owl. The owl dies, falls to the ground, and is found and eaten by a Carrion Crow, which in turn dies and is eaten by a whole truckload of animals from fly maggots, slugs, mice, and Red-Tailed Kites, to the odd very hungry fox. The droppings from all of these things fertilise the soil to provide nourishment for trees, which die, fall, and provide food and shelter for, guess what? The springtails. And this is just one example. Imagine all the different strands! I could have followed a slug, which will certainly have mites, and might be eaten by a hedgehog, which probably has ticks which are eaten by birds or predatory insects … you see where I’m going with this. And as you will know, all of this delicate balance is affected by temperature, by rainfall, by lack of food, by pesticides & weedkillers, by over-fishing, by agriculture, by … yes, and by our management of gardens.
To close this blog I will leave you with a statistic: if you add all of the gardens of the UK together, they collectively cover more ground than all of our nature reserves put together.
Oh yes. We can make a significant difference.
* Oh, fungi … that is a huge, and hugely important story all by itself. And it’s one on which so many things depend, including us.
