Biodiversity and conservation

In the past 50 years, global wildlife populations have fallen by 68 per cent. This biodiversity loss is driven by changes in land use, climate change, herbicides and pollution. Taking action to improve biodiversity locally is a key element of our Climate and Ecological Emergency work, which is one of our six Corporate Priorities.

Wildflower meadows

The UK has lost 97 per cent of its wildflower meadows in less than 100 years.

Wildflower meadows and areas of long grass provide a range of essential benefits:

  • Wildflowers provide essential homes and food sources for pollinators such as bees, butterflies and other insects, which in turn are crucial for supporting larger wildlife populations that depend on them, such as birds and mammals.
  • They can contain up to 40 different species per square metre, making them a precious resource for enhancing biodiversity and preserving native UK species.
  • They can store up to three tonnes of carbon per hectare. This helps to reduce the amount of carbon in the atmosphere and mitigate climate change.
  • These types of habitats are much better suited to dealing with extremes of wet and heat, and are able to absorb large quantities of water – making them useful in helping to play a role in mitigating future flooding events.
  • These biodiverse areas act as a gateway for everyone to enjoy the natural world in their local community and provides more opportunities to learn more about nature and interact with wildlife.

We have been actively creating more wildflower-rich and biodiverse grasslands across the borough. These areas are managed differently, to encourage them to flourish. The grass may have a different cutting regime to encourage wildflowers to grow, be seeded with wildflower seeds, or laid with wildflower turf.

We have created an interactive wildflower map to show which areas we are carrying out this work. Take a look and discover which areas are close to you:

To help you identify these areas, we have also installed some colourful signs in the areas where we have created meadows - look out for them on your next walk.

Please note: it can take a while for these areas to establish - in the meantime they may include docks, thistles and nettles. While many people would class these plants as weeds and would not want them growing in their garden, in the wild, these are important food and breeding sources for many different species and with time the areas will become beautiful biodiversity hotspots.

Solitary bees

Solitary bees are in decline, due to loss of habitat and modern farming practices. They provide an essential function, pollinating our crops and ensuring that plant communities are healthy and productive. Without them, mammals and birds would not have the seeds, berries or plants on which they depend, with approximately one in three mouthfuls of food and drink requiring pollination.

As part of our biodiversity commitment, we have been introducing bee houses to our parks and open spaces. These little houses encourage declining solitary bees, like the Red Mason and Leaf-cutter bees to start nesting and laying eggs in the small cardboard tubes that the houses hold.

At the end of the summer, these tubes are safely transported across to Mason Bees UK. The bee cocoons are removed from the tubes and checked for parasites and anything else that may harm them. Once this is done, the cocoons are kept safe over the winter. When spring arrives, they are sent back to us and the whole process starts again.

Pollinator-friendly plants

Pollinators such as bees, butterflies and other invertebrates are critical to our own existence. To ensure their ongoing survival, we plant pollinator-friendly plants wherever we can. These plants provide the much-needed nectar and pollen that bees, butterflies and other insects rely on to survive. Examples of pollinator-friendly plants include Nepeta (Cat mint), Achillea, Helenium and Echinacea.

Gadebridge Park River Restoration

River Gade, Gadebridge Park

We're working with the Environment Agency and Affinity Water to help restore the River Gade in Gadebridge Park, a globally rare and valuable chalk stream. The project will provide multiple benefits, including improved habitats for wildlife, the protection of water resources for both people and the environment, and allowing local residents and visitors to get closer to the river and enjoy nature.

This project is part of Revitalising Chalk Rivers, a wider programme of projects led by the Environment Agency and Affinity Water that aims to protect and restore rare chalk streams. As part of this programme, Affinity Water has recently completed a project in the upper section of Gadebridge Park to provide new river habitats for wildlife and to improve the river’s water quality. Find out more about this project.

Our latest proposals will improve the river in the lower section of Gadebridge Park, between the Grade II-listed White Bridge and Queensway.

The Environment Agency and Affinity Water are funding the river restoration project and we will be contributing to its recreational and amenity aspects. We expect the restoration works to begin on site in spring 2023.

More information

The Environment Agency will soon be sharing its draft detailed designs. You will be able to view the designs and provide your comments on the Environment Agency’s website

If you'd like to join the Environment Agency’s mailing list to receive future updates, including when the draft detailed designs are available to view, please email gadebridgepark@environment-agency.gov.uk.

In the meantime, if you have any questions we will be happy to help:
