Ecology experts are calling on urban residents to take action to support local wildlife this spring and summer, as new data reveals how disconnected city dwellers are from the natural world.

The British Wildlife Insights report, released by ecology consultancy firm Arbtech, found that just 1 in 3 Londoners have seen a hedgehog in the last five years – a stark contrast to the national average of 52%.

The survey, which asked 2,000 UK adults about the wild animals they’ve spotted across the country, highlights the species that are now rarely seen – even outside of the capital.

Otters, moles and seals were among the least spotted, while foxes, rabbits and deer were the most common sightings in the capital.

And despite widespread concern about biodiversity loss, city residents are falling behind when it comes to taking action.

91% of Londoners say they’re worried about the decline in UK wildlife, yet 28% admit they’ve done nothing to support wildlife locally.

So Arbtech is urging people living in urban areas to take simple steps to help reverse the trend.

Suggested actions included leaving out food, water, and shelter, taking part in conservation efforts, and supporting local wildlife charities – providing options even for those without a garden.

The report reveals that the further people live from natural habitats, the more likely they are to lose touch with Britain’s native species – an issue that experts warn could lead to long-term indifference unless addressed.

In London, only 30% of residents have seen a hedgehog in the past five years – well below the national average of 52%.

And similarly, while 62% of the UK population have spotted a wild deer, this drops to 55% among Londoners.

Commenting on the report, a spokesperson for Arbtech said: “It’s alarming to see how scarce some of the UK’s most iconic species have become. In London, only 30% of residents have seen a hedgehog in the past five years – well below the national average of 52% – while sightings of wild deer are also less common in the capital compared to the rest of the UK.

“This reflects a broader issue: habitat loss and urbanisation are making it harder for wildlife to thrive and for people to connect with nature.

“The fact that almost a third of respondents living in London take no action to support local wildlife, despite widespread concern for its decline, highlights the urgent need for greater public engagement – even in urban areas.

“Small steps, like leaving out food and water and donating to local wildlife charities can make a real difference in reversing this worrying trend.

“Even small changes can have a meaningful impact. Whether you have a garden, a balcony or just a windowsill, there are ways everyone can support local ecosystems.”

Five ways Londoners can help wildlife:

Put out food and water

Leave a shallow dish of water on a balcony or windowsill, and scatter bird seed or chopped fruit to help birds and hedgehogs – especially during dry spells or cold snaps.

Create a mini wildlife corner

Even a small planter box or window box with pollinator-friendly plants (like lavender or wildflowers) can provide food for bees and butterflies.

Join local conservation groups

Get involved in local wildlife initiatives or community gardening projects. Many London boroughs have conservation schemes or volunteering opportunities with charities like London Wildlife Trust.

Be a wildlife-friendly neighbour

Avoid using pesticides, and leave part of your garden, balcony or outdoor space a little ‘wild’ to give insects, frogs or hedgehogs a safe haven. If you live in a flat, you could even encourage your building manager to consider green roofs or planting schemes.

Report sightings and support research

Use apps like iNaturalist or participate in national surveys to record wildlife sightings. This helps conservationists monitor populations and protect endangered species.
