Gardening for wildlife…but
Part One
Gardening for wildlife is great, hugely rewarding and satisfying.
I’m confident that most of us can agree on that.
Like many others, both at home and at our allotment, we’ve embraced pollinator-friendly planting and solitary bee hotels. We’ve added ponds, log piles and messy corners to our plots and, with residential gardens collectively covering around 4–5% of UK land, the way we manage them really does matter for wildlife in an increasingly nature-depleted world.
But – and it’s a big but…a huge, stonking capital-letter BUT…even if every single garden in the UK were finely tuned for biodiversity, the total area would still be insignificant compared with the dominant land use, and main driver of nature loss in this country: animal agriculture.
Almost 70% of the UK’s land surface – around 17 million hectares – is farmed, the majority of it for livestock grazing or to grow feed crops rather than food for people to eat directly. Vast tracts are given over to cattle and sheep, or to producing cereals and protein crops that are consumed by farmed animals long before they reappear, vastly diminished from a protein and calorific point of view, on our plates as meat, dairy and eggs.
The Hidden Cost of Our Countryside
The ecological consequences of this are huge. Habitats are fragmented, simplified or erased altogether, often leaving a biological desert. Species-rich grasslands become monocultures or tightly grazed pasture with little structural or floral diversity. Feed crops such as wheat and barley are commonly grown in intensive systems that lean heavily on pesticides and herbicides, compounding the damage.
Pesticides are designed to kill, and they’re not fussy about who, inevitably poisoning non-target insects including pollinators and the less charismatic species that keep ecosystems ticking. Herbicides strip away wildflowers and “weeds” – precisely the plants that support grubs, insects, birds and soil life. These chemicals, together with slurry and fertiliser run-off from livestock systems, don’t politely stay put; they seep into soils, rivers, groundwater and even the air, contributing to a wider fog of pollution and contamination.
Long-term monitoring paints the same grim picture. Farmland bird populations have collapsed since the mid-20th century, while insect numbers have plummeted, with some studies suggesting declines of over 60% in just a few decades. Hedgerows and orchards have been grubbed out, wetlands drained, field margins shaved to the nub. The modern farmed landscape is, in many places, increasingly hostile to the very species that underpin soil health, pollination and natural pest control.
Shifting Baselines and Silent Mornings
For old farts like me, this isn’t an abstract statistic; it’s a lived experience. In my own lifetime, the changes have been dramatic. Dawn choruses that once were almost cacophonous at home in south-west London have diminished to token twitters. On summer evenings we can throw open the windows with the lights blazing and barely see a moth, let alone clouds of insects we were once used to.
Younger generations won’t notice. Shifting baseline syndrome means that what we’re experiencing now is, for them, normality. They’ll never know who they’ve lost but anyone with a memory stretching back a few decades can see that nature is fading in front of our eyes – if we’re willing to open them that is.
Today the UK is routinely described as one of the most nature-depleted countries on Earth, with collapsing insect populations, dwindling farmland birds and degraded soils now familiar features rather than distant warnings.
Land Use, Diet and the Space for Recovery
Against this backdrop, wildlife gardening is both a blessing and a distraction. It’s a blessing because it shows a growing public appetite to help, and gardens genuinely can provide vital oases for insects, birds and small mammals. It’s a potential distraction because it risks suggesting that biodiversity collapse can be fixed with a few bee-friendly perennials and a mini-pond while we ignore what’s happening across the 70% of land used for farming.
If we’re serious about tackling the crisis, we have to talk about diet and land use. Plant-based food systems are far more land-efficient than livestock production because they skip the wasteful step of feeding crops to animals first. Research by Poore and Nemecek shows that moving towards a global plant-based diet could reduce food-related land use by about 76% – freeing up an area of land approximately equivalent to the size of Australia, China, the EU and the USA combined…!!!!! That’s a mind-boggling statistic by any standards but one that the meat and dairy industries would like to keep hidden from consumers.
Freed land is not an empty abstraction; it’s the physical space in which ecosystems can mend, forests recover, rivers breathe, and soils rebuild their intricate life.
Rewilding, allowing natural processes revive, has shown remarkable results where it’s been tried. Projects like Dunsany in Co Meath, Ireland demonstrate how quickly birds, insects and plants can rebound when grazing pressure is relaxed and landscapes are allowed to become messy, dynamic and diverse again. Set aside agricultural land for nature and the benefits, in terms of biodiversity, carbon storage, flood mitigation and water quality, can be transformative.
The problem is that animal agriculture is barely mentioned in the gardening press when talking about biodiversity collapse or climate change. In part two I’ll cover why.
