Great Crested Newts in Heath Park Pond and the Flora and Fauna of Heath Park

Heath Park is a wonderful nature conservation area

Heath Park in Cardiff is a wonderful area for nature conservation and is home to a colony of the rare great crested newt (Triturus cristatus). The amphibians breed in the pond there that has been in the park for very many years.

Great Crested Newts

Those responsible for the park and pond’s upkeep have very wisely left dead tree-trunks around the edges of the pool and in the woodland that surrounds it.

Water plants, such as watercress (Nasturtium officinale) are enclosed in mesh so that they are protected and this creates a wonderful area for the newts to lay their eggs in and to hide. Great crested newt females wrap their eggs in the leaves of aquatic vegetation, as do other species of newt.

An information board gives a lot of information about the great crested newt, including how far it travels away from water. The much smaller palmate newt (Lissotriton helveticus) also breeds in Heath Park Pond. This comes as no surprise to me because I used to have a girlfriend many years ago, who lived in the nearby King George V Drive that circles Heath Park, and these far commoner newts could be found in the garden pool of the house where she lived. On the info board, there are illustrations and notes about the other interesting species of wildlife that can be seen in the pond. The common frog (Rana temporia) is another amphibian that breeds here.

Aquatic insects that use the Heath park Pond include the great diving beetle (Dytiscus marginalis), the water boatman (Notonecta glauca) and dragonfly and damselfly species. The great diving beetle and its larva hunt tadpoles, small newts, fish and worms. The larvae have large mandibles with which they grab their prey as they suck out the life-blood. Both adults and larvae will bite. The adult beetles fly by night to look for suitable stretches of freshwater. The water boatman or backswimmer can also fly. It is a predatory bug that feeds on mosquito larvae and other small water creatures. It gets its name from its habit of swimming upside down and using its legs as paddles to propel it through the water.

Alien and invasive species

Parrot's Feather

The information board includes a warning and request: the public are asked not to release species that are non-native and alien to this country. An example being species of terrapin that can be a danger to British wildlife. The species of water milfoil known as parrot’s feather (Myriophyllum aquaticum) is mentioned as an example of an invasive species, and it is pointed out that this particular plant caused a problem at Heath Park Pond where it grew abundantly and had to be carefully removed. It is a threat to British species because it grows so well that it displaces native plants.

Elsewhere in Heath Park

Elsewhere in Heath Park they have constructed a second pond near the golfing area. The information board explains that great crested newts do best in places where there are more than one pond, so that if one pond dries up in hot weather, for example, the amphibians can still breed in another. I don’t know if any newts are using it but it is certainly big enough and there were two mallard drakes swimming around on it.

Walking a dog to Heath Park Main Pond

There is quite a lot of woodland and areas which were once rough ground and scrub have been allowed to grow into thickets of small trees and bushes. There are plenty of great places for birds and other wildlife to live in the park. It is reported that the green woodpecker (Picus viridis) lives in this woodland, and I wouldn't be at all surprised because it is a great place for them.

Paths help you enjoy walking around the woodland and many people take their dogs for walks in Heath Park.

In the grassland and extensive lawns of Heath Park there are extensive colonies of lady’s smock or cuckooflower (Cardamine pratensis), which takes its name from its habit of flowering around the time when the first cuckoos could be expected to arrive in the UK.

It is of especial interest, and a useful plant when it comes to wildlife conservation, because it is one of the main food plants of the caterpillar of the orange tip butterfly (Anthocharis cardamines). This pretty species, with orange tips on the forewings of the males, has been increasing again in numbers in some parts of Britain, so anywhere that plants that its larvae feed on grow, is going to be helpful in ensuring this butterfly’s survival. The cuckoo flower used to be gathered as a substitute for watercress, and like the latter plant it likes to grow near water.

The abundance of lady’s smock plants in the park, as well as the natural woodland, and the obvious great attention that had been paid to making the ponds a suitable habitat for great crested newts and other aquatic wildlife, made me feel that Heath Park is one of the best parks in Cardiff for nature conservation.

Pentrebane Farm, Barn Owls and the Great Crested Newt

Barn Owls and Great Crested Newts Threatened by Plasdwr

Steve Andrews and Michael Deem at Pentrebane Farm

The Plasdwr housing development plan threatens to destroy green belt countryside on the outskirts of Pentrebane, St Fagans and Radyr in the west of Cardiff. Rare species, such as the barn owl (Tyto alba) and the great crested newt (Triturus cristatus) live and breed in this area. Pentrebane Farm is one place they can be found and if those behind Plasdwr and Redrow Homes, who are doing the building, have their way, this historic farmhouse will be converted into a pub and the fields will be built all over.

TV presenter and naturalist Iolo Williams has called the Plasdwr proposal “sheer madness” and has pointed out that it threatens many species, including the great crested newt, the barn owl and the lesser horseshoe bat (Rhinolophus hipposideros). Williams is not only very concerned about the destruction of the habitats of these species, but also explains that the building of some 6,000 houses will mean a lot more traffic on the already overburdened roads in and out of this side of Cardiff.

A visit to Pentrebane Farm

Sue Caldwell and Michael Deem

I went along to Pentrebane Farm with my friends Sue Caldwell and Michael Deem. Michael, by the way, is a councillor for Radyr and Morganstown Community Council and South Wales Central Regional Assembly Candidate at Plaid Cymru. Along with Neil McEvoy, Assembly Member for South Wales Central at Y Senedd, he has been campaigning ardently against Plasdwr.

Michael Deem makes a new friend

My first impression of Pentrebane Farm was what an amazing place it is, and this impression was to be confirmed and to grow. The farm is a still-surviving example of an old-style farm with a muddy farmyard, barns full of hay, cowsheds, cows out in the fields, several friendly sheepdogs, and a stables for the horses.

Pentrebane Farm

There are plenty of green fields, hedges, trees and large pond with a stream. Pentrebane Farmhouse is a Grade II Listed Building in St Fagans. It dates back to the 18th century and has a largely unaltered Victorian character. The views are wonderful in this very rural setting.

Barns and Barn Owls

Pentrebane Farm Barn

Amongst its attractions are its barns. Barn owls nest in these in the special boxes placed there for them. There are two pairs using the farm as a place to live and hunt from. These owls are having problems throughout the UK and a home for them such as this is vital for their survival and wellbeing.

Inside the Barn

It would be a real tragedy to think that this majestic barn could one day just become part of a modern public house, if the planners get their way. The barn owls would no longer have this wonderful home, and if somehow they managed to adapt, they would have to hunt over houses and streets, instead of the fields and countryside.

Pentrebane Farm Pond

 Pentrebane Farm Pond

We went to have a look at the pond too. It was very muddy but we all had ‘wellies’ on and I went wading about in the shallow. Sue’s dog Cleo jumped in and made the water even muddier. I didn’t see any newts but could see that it would be a great place for them. Newts don’t mind a lot of mud! The experience took me back to my childhood when I used to spend a lot of time wading around in ponds, as can be read in previous blogs about ponds and newts.

Redrow Homes have already started

Redrow Homes Danger Sign

Right next to Radyr, Redrow have already been given the go ahead and have begun work. They have fenced off fields that are all ploughed up. Hedges have been felled, bulldozers, ‘Keep Out,’ and warning notices complete the depressing picture. It is too late here but, hopefully, not for Pentrebane Farm and other parts included in the Plasdwr plan.

The Solution

Fields

Iolo Williams explained on a video presentation, in which he talks about the problem of Plasdwr, that a solution exists. Obviously houses need to be built somewhere but there are brownfield sites in the Cardiff area that could be utilised without any need to destroy the beautiful countryside threatened by the plans. Concerned residents are urged to contact their AMs and local MPs and voice their worries. Let’s Say NO to Plasdwr, and Save Our Green Fields!

TV presenter Iolo Williams speaks out against the Plasdwr housing plan

Plasdwr threatens the Great Crested Newt and other wildlife

Popular TV presenter and naturalist Iolo Williams has spoken out against the Plasdwr housing development proposal that threatens to destroy countryside in the green belt area of Cardiff northwest. Plasdwr is being promoted as “Cardiff’s garden city” but Williams calls the plan “sheer madness.”

He points out that already endangered wildlife species, including the great crested newt (Triturus cristatus), the barn owl (Tyto alba) and the lesser horseshoe bat (Rhinolophus hipposideros) all have populations that depend on habitats that exist on land scheduled for use, if the building of 6,000 new houses goes ahead.

The plan of Redrow Homes is to build all over countryside bordering on St Fagans, Fairwater (Pentrebane), Danescourt and Radyr, all on the outskirts of the north-west of Cardiff. There are large ponds in the fields and farmland affected by the housing development proposals, ponds, such as the Pentrebane Cottage Ponds, that are known to be used by the great crested newt, an amphibian that has been declining fast in the UK and is protected by law.

Barn Owl (Photo: Public Domain/Pixabay)

The barn owl is another British species of wildlife that has been dropping in numbers throughout the UK and is the subject of conservation schemes set up to protect this beautiful nocturnal bird of prey. Williams has pointed out that this magnificent bird is found in the area threatened by the development of the land.

The lesser horseshoe bat is one of the smallest mammals in the world. It roosts in colonies and in the UK, Wales is one the parts it is found. This bat is absent from Scotland. Threats to its survival include disturbance and destruction of roosting locations and the loss of suitable habitats in which it can forage for its prey, which are small insects and spiders. This bat flies low over the ground and will grab small creatures it can eat off of rocks and bushes.

Cardiff Council and the Local Development Plan (LDP)

Cardiff Council are favouring developers over the wishes of residents of the city when it comes to its LDP.  A report by Ruth Mosalski for WalesOnline points out that Cardiff’s Civic Society has claimed that Cardiff Council “ignores the public.” Many residents of the city are worried about these development plans and have voiced their concerns. It is not only because of the threatened destruction of the countryside and the wildlife it is a home to that is causing worries, but also because of the very real problem of traffic. Roads into and out of the west of Cardiff are already experiencing traffic chaos and adding another 6,000 houses and a potential 10,000 more cars can only acerbate the problem turning it into an absolute nightmare. Cardiff simply does not have the roads in place to cope with the increased traffic.

Increased traffic causes increased air pollution too. At present, the growth of lichen and mosses on tree trunks and walls throughout the city shows that the air quality has improved, but a dramatic increase in the number of vehicles using Cardiff’s overburdened roads will halt and reverse this, as well as being a known cause of ill-health for people.

There is a solution

There is no denying that people need somewhere to live and that more housing should be built. However, none of the problems the Plasdwr development will create have to exist because a viable solution already exists. As Williams points out in the video, there are brownfield sites in Cardiff where houses can be built instead. Also there are empty buildings that could be used to provide housing. He asks concerned residents to get in touch with their AMs and local MPs and to put in their complaints.

Councillor for Radyr & Morganstown Community Council and Plaid Cymru candidate for Radyr and Morganstown, Michael Deem, is campaigning against the destruction of the green belt, and so is Neil McEvoy, who is Assembly Member For South Wales Central at Y Senedd and County Councillor for Fairwater.

Say NO to Plasdwr, Save Our Green Fields!

The Coal-yard

The Coal-yard That Became Housing

Restharrow - Ononis repens (Photo: Public Domain)

Today, I am going to write about somewhere my family called “The Coal-yard.” It was on the other side of the railway line and railway bank behind where we lived. As a child fascinated by nature, I used to go there to look for wildflowers, butterflies, moths and once common reptiles. The coal-yard was a wonderful unrecognised nature reserve because it supported so many species of wildlife. It was presumably viewed by the local authorities as little more than waste ground, of no use now the coal mines were no longer a thriving business and British Railways were no longer using it. What was once my coal-yard was destroyed and became a site for housing and a short road, together with the almost obligatory lawns.

All of the wildflowers and wildlife have gone, including the common lizards that lived there.

I recently blogged about habitat destruction and natural environments that I have seen destroyed and vanish locally. The same picture is happening globally. Just think about how many woods, fields, ponds or other wild places that have gone from the area you live in. I am sure you will know what I mean.

Here is a poem I wrote describing the coal-yard and what was once there.

Common Lizard (photo: Public Domain)

The Coal-yard of my Vanishing World

The coal-yard has long gone,

Once there were wildflowers in the abandoned sidings,

Pink restharrow, golden bird’s-foot trefoil and purplish tufted vetch

Added colour to the picture

And nectar for the bees and butterflies;

Small heath, small copper,

Common blue, grayling,

Wall brown, meadow brown,

Small tortoiseshell, and the day-flying burnet moths,

Once added their beauty on the wing,

Flitting from one floral delight to the next,

Basking in the sunlight.

Lizards sunned on sleepers and anthill mounds,

Slow-worms slithered under rusty corrugated iron;

Catch them if you can, and I often did.

It was a boy naturalist’s paradise,

Over the railway bank,

A secret heaven,

A pasture of delights.

Now apartment blocks, a cul-de-sac

And manicured lawns are the replacements.

Plums and apples fall in season

And rot on the grass,

Where tenants leave them,

And passers-by pass by.

People are starving elsewhere in my vanishing world.

About the Butterflies

Several species of the butterflies mentioned are now recognised as being in a serious decline in numbers throughout the UK. The small heath (Coenonympha pamphilus) is, as its name implies, a small butterfly and fairly inconspicuous with its yellowish-brown wings. It likes a grassy area and its caterpillars feed on various grasses. It was once very plentiful, and although still widely distributed, many of its former colonies have gone.

The wall brown, or simply wall butterfly (Lasiomammata megera) was once very common but has suffered serious declines, although Climate Change is thought to be a reason behind its disappearance. Like the small heath, its caterpillars feed on grasses, so lack of food-plants is not a problem for these species.

Small Tortoiseshell (Photo: Public Domain)

The small tortoiseshell (Aglais urticae) was once one of the most common British butterflies and was found in a  wide range of habitats, including our gardens. Over the past decades, however, it has experienced a dramatic slump in its number. This is not adequately explained because its food-plant is the stinging nettle and there are plenty of these plants about. It is thought that changes in weather brought about by Climate Change are negatively affecting this pretty butterfly.

Forest Farm and Glamorganshire Canal are Great Places for Nature

Forest Farm Reserve and the Glamorganshire Canal

Just on the outskirts of Cardiff lies a wonderful area for nature that I have been visiting since I was a boy. I am talking about Glamorganshire Canal and the Forest Farm Nature Reserve, which offer long stretches of freshwater, pools and wetland habitats, forests and fields.

Photo: Steve Andrews

There are several ways to get there but I usually walk up through Hailey Park in Llandaff North and continue along Ty-Mawr Road that goes past the old Melingriffith Tin and Iron Works and the old water wheel which is still there as a relic of the South Wales industrial past. The Melingriffith Works that were founded sometime before 1750, closed in 1957.  At the end of the road you reach the end of Velindre Road, which is part of the suburb of Whitchurch.

Here you can either go into the Forest Farm reserve or wander along the banks of the canal, which ends below Tongwynlais and in the area of the Coryton Interchange. It is also possible to get there by crossing the River Taff from Radyr.

Herons and Kingfishers

Birdwatchers can easily spot herons in this area and if lucky you can get a glimpse of the kingfisher too as it hunts for prey in the waters of the canal. I remember seeing one there many years back and it inspired me to write a song, aptly entitled "Kingfisher."

Mallard ducks are very common here and can be seen on the Glamorgan Canal and on the feeder which runs alongside it, as are moorhens. Water rail, snipe, dippers and reed warblers are also reported from Forest Farm Reserve. Even the elusive bittern have been seen here.

Beech and Oak

Beech and oak are the main trees that grow alongside the Glamorganshire Canal and in the Long Wood. Some of the trees are said to be 200 years old. In autumn the dead leaves in their brown and golden autumnal shades can be seen coating the ground and floating on the canal’s surface.

Common Toads

Common toads gather to spawn in the canal in springtime, and I remember when some ponds many miles away on the banks of Llandaff Weir were destroyed many years ago. I remember seeing toad tadpoles in the canal that year and wondered if it was possible that some of the displaced toads had somehow found the canal even though it was miles away. I often wonder what amphibians do when they return to spawning grounds to find them gone.

Grass Snakes

I have seen grass snakes swimming in the Glamorgan Canal too. It is good to know these once much more common reptiles, have found a home here.

Waterlilies

In summer the surface of a lot of the Glamorgan Canal is covered by the large rounded leaves of the yellow water lily. However, when I recently visited in late autumn they had all died back. Nevertheless, I really enjoyed my recent walk along this canal that is an interesting place to visit all year around.
