The 2019 State of Nature report shows the UK’s biodiversity is declining and 15% of species are threatened from extinction, but what can we do to help? Here are some tips from on what you can do to give mother nature a helping hand:

Leave nature as you found it
Stick to designated paths in areas where your footsteps might erode or destroy important habitats, and don’t collect natural souvenirs without careful consideration of how it might affect wildlife!

Think about what you pack
Avoid single-use plastic like water bottles and take a reusable shopping bag, whether it’s to local markets or windswept hilltop picnics.

Take public transport where possible
You’ll help carbon emissions and reduce the environmental damage caused by vehicles on delicate thoroughfares by taking a bus or a train to the nature spot.

When you’ve got to your destination, stretch those legs! As long as you’re respectful of animals and their habitats, the best way to enjoy Mother Nature is up close.

Go local
By consuming local products you’ll save on the carbon emissions and packaging waste created by long-haul transportation.

Support can be a souvenir
Many beauty spots are maintained and protected by charitable bodies like The National Trust. A small donation or show of support will help preserve the local fauna and flora.

Shannon Keary from had this to say: “We’re becoming increasingly aware of the environment and our impact on biodiversity. At we want to encourage people to explore and enjoy what mother nature has given us in different areas of Great Britain, whilst doing their bit to preserve the local wildlife for future generations to come”.

Notes to editors
All data on the number of species was extracted from National Biodiversity Network Atlas as species having at least 1 occurrence within the boundaries of a given local area. Areas with the highest total number of distinct species were deemed more biodiverse and areas with a lower count of distinct species were deemed less biodiverse.
