Wildflowers are finding a surprising refuge in urban areas across the UK, despite facing significant challenges in the countryside. Intensive farming practices, including the use of fertilisers, pesticides, and herbicides, along with reduced grazing, are major factors contributing to their decline.
The UK has seen a 97% loss of its wildflower meadows over the last century, and more than half of the country's native flowers have been in decline for 70 years. Other pressures include building developments, competition from invasive plant species, and the climate crisis.
Cities, often perceived as stressful environments, can paradoxically benefit wildflowers by limiting competition from other plants like grasses. Wildflowers generally thrive in low-fertility soils, which allows them to establish themselves. Urban areas also offer a variety of specialised habitats and microclimates in places such as pavement gaps, walls, roadsides, disused railways, and riverbanks.
Even derelict sites can serve as plant refuges. Some of the most effective environments are those where local councils intentionally avoid using herbicides and restrict mowing to encourage wild plant growth.
