Nature in Caerphilly

Caerphilly County Borough lies in the South Wales Valleys, bordered to the south by Cardiff and Newport and to the north by Powys and the Brecon Beacons National Park. The county contains 23 diverse habitat types, including species-rich and marshy grasslands, fragments of ancient woodland, and an extensive network of rivers and ponds. This wealth of habitats supports a wide range of species, notably an important maternity roost of greater horseshoe bats and a strong population of the marsh fritillary butterfly. Other species, such as Cornish moneywort and the peregrine falcon, are also of significant local importance.

About

The Caerphilly Nature Partnership is a collaborative network of people and organisations committed to nature recovery and biodiversity enhancement within Caerphilly County Borough. It brings together a wide range of partners including members of the public, council representatives, land and business owners, public services, and wildlife professionals, to share ideas and work collectively towards improving our local environment. The partnership currently has over 100 members, representing more than 40 organisations such as Natural Resources Wales, Amphibian and Reptile Conservation, Buglife, and Gwent Wildlife Trust.

The Partnership is open to anyone interested in joining. Members can access quarterly meetings, resources, events, and opportunities including volunteering roles, research projects, and citizen science initiatives.

Our Aims

The main aim of the Nature Partnership is to conserve and enhance biodiversity in Caerphilly.

Our additional aims are to:

  • Protect existing habitats, restore former habitats, and create new ones.
  • Educate people of all ages about the importance of biodiversity and how to support its conservation.
  • Encourage the community to get outdoors and enjoy their local wildlife.
  • Research and survey species and sites to increase and share knowledge.
  • Promote activities and behaviours that are sensitive to local wildlife.

Train and support amateur naturalists and students, providing valuable CPD opportunities to help build the future of biodiversity work.

How are we going to achieve it

We plan to achieve our aims by:

  • Publishing the Caerphilly Local Nature Recovery Action Plan (NRAP) in 2026, which will identify priorities for nature recovery and ecosystem resilience across the county.
  • Using the Nature Partnership to build strong collaborations between people and organisations that protect and care for nature.
  • Supporting development that contributes to the aims of the Partnership, addresses local priorities, and helps inform and strengthen funding applications for nature recovery projects.
  • Delivering school outreach by presenting information on local flora and fauna and providing materials such as bird boxes, hedgehog homes, and otter holts.
  • Supporting and facilitating community engagement through events such as Go Wild!
  • Carrying out research and surveys throughout the year, including the annual marsh fritillary web survey and great crested newt surveys.

Examples of work completed or underway include:

  • The management of 9 country parks and nature reserves, as well as additional nature sites by CCBC.
  • Installation of heronry platforms to support local heron populations in Fochriw.
  • Community-led restoration work converting land to native heathland in Aberbargoed.
  • Annual marsh fritillary web surveys at Aberbargoed Grasslands
  • Dipper and Wagtail box scheme along Rhymney, Sirhowy, and Ebbw rivers by Glamorgan and Gwent Bird Club
  • A wildflower meadow, pond, and education session log circle have been restored and created in Parc Coetir Bargoed
  • 4 artificial otter holts were placed along the River Rhymney as it cuts through Parc Coetir Bargoed in a partnership with CCBC and Gwent Wildlife Trust with the assistance of pupils from Ysgol Gyfun Cwm Rhymni.

Becoming a member is the best way to access resources, information, events, volunteering opportunities, research projects, and citizen science initiatives. Get in touch if you’d like to get involved!

Volunteer
For opportunities within Caerphilly Council, click here. For other opportunities, join the Nature Partnership to stay up to date. Volunteering activities may include habitat management and restoration, species and habitat surveys, wildlife rescue and rehabilitation, and helping to organise events.

Record
Submit your wildlife sightings to the South East Wales Biodiversity Records Centre (SEWBReC). These records help us understand changes in wildlife populations and identify areas where conservation efforts are needed. You can also take part in citizen science surveys run by conservation organisations, which provide all the guidance you need to begin identifying and recording wildlife. Popular initiatives include The Big River Watch, Big Butterfly Count, Big Garden Birdwatch, and Flower-Insect Timed Counts.

Garden
You can create a wildlife haven in your own garden. Recommendations include planting wildflowers, installing bird boxes and feeders, creating hedgehog highways, adding a mini pond, composting, leaving dead wood and rock piles, installing bee hotels, avoiding artificial pesticides and fossil-fuel-derived fertilisers, and taking part in No Mow May. Find more tips here.

Invasive Species Management
Learn to recognise invasive species (e.g. Himalayan balsam, Japanese knotweed, American signal crayfish, American mink). Report sightings to Caerphilly Council’s Countryside & Landscape team or through the INNS Mapper. You can support biosecurity by cleaning gardening tools and boots after use to prevent spreading seeds or spores, and by washing boots after entering waterways to avoid transferring crayfish eggs. For more information click here. Keep up to date with ongoing initiatives run by wildlife organisations, such as the UK Squirrel Accord and INCC’s South Wales American Mink Partnership.

Training & Education
Everyone, from beginners to experienced naturalists, can benefit from training and continued learning. Organisations such as the Field Studies Council and the Bat Conservation Trust offer high-quality resources, courses, and seminars. Partners in the Nature Partnership also deliver workshops and presentations, and the annual Wales Biodiversity Partnership conference provides valuable learning and networking opportunities.

Places to see nature in Caerphilly

Caerphilly offers a wide range of locations where you can enjoy its rich biodiversity. Here are some examples:

Aberbargoed Grasslands National Nature Reserve
Designated as a Site of Special Scientific Interest (SSSI), this reserve is protected as a site of European importance. It supports a strong population of Marsh Fritillary butterflies and features Purple Moor grass and rush pasture habitats.

Ynys Hywel Farm
A vibrant community hub hosting regular events and allotments. The farm is also home to an impressive variety of fungi species, including waxcaps.

Parc Cwm Darren
Once the Ogilvie Colliery industrial site, this area has been transformed into a wildlife-rich landscape with grasslands, woodlands, lakes, and the Cwmllydrew Meadows Local Nature Reserve. It has earned a Green Flag Award and contains coal spoil heaps that provide vital habitats for invertebrates and fungi.

Llanbradach Quarry
An abandoned quarry now thriving as a haven for wildlife has been designated a SSSI. Its exposed rock faces and surrounding scrub provide nesting sites for birds, including the Peregrine falcon, and habitats for specialist plants and invertebrates. This site is moderately accessible and suitable for experienced walkers and birdwatchers.

Parc Cefn Onn

A Grade II listed historic country park, providing access to the footpath network of Caerphilly Mountain. The park is renowned for its woodland gardens, streams, and ponds, creating a tranquil setting rich in wildlife. It features a diverse collection of native trees, seasonal floral displays of rhododendrons, azaleas, camellias in spring, and the largest of two remaining frog orchid populations in South Wales.

More details on other country parks and nature reserves can be found here.

Highlights

Marsh Fritillary Butterfly
South Wales is a UK stronghold for this rare species. Aberbargoed Grasslands is a key site, where Nature Partnership members such as Butterfly Conservation work to maintain and improve habitat quality.

Coal Spoil Habitats
Caerphilly’s coal spoil heaps are vital for invertebrates and fungi, supporting heathland, species-rich grassland, woodland, and wetlands. Buglife recently hosted a conference on their ecological value in Gwent.

Greater Horseshoe Bat Roost
Ruperra Castle hosts one of only five maternity roosts in Wales, and the only one in south-east Wales. The castle and surrounding woodland are designated as an SSSI. Guided bat walks are held annually by our partners at Ruperra.

Frog Orchids
These orchids have declined due to agricultural changes, under-grazing, and drought. Parc Cefn Onn supports the largest of two remaining populations in South Wales.
