Walking in the Wentloog Levels Where Wetlands Meet the Sea

Wentloog Levels aka the Gwent Levels are a Wildlife Haven

I recently went on an epic 7-hour walk in the Wentloog Levels, starting off in the aptly named Marshfield I went to St. Brides where I followed a road to a Welsh Coastal path along the sea wall. I was revisiting an area of important wetlands that lie to the east of Cardiff and extend to the outskirts of Newport. Also known as the Gwent Levels the area bears a resemblance to the Netherlands because it is flat land reclaimed from the sea and traversed by drainage dykes, which are locally called “reens.”

Rare Species

The Wentloog Levels are of great importance because of the amazing variety of species of flora and fauna that live here, some of which including the Lapwing (Vanellus vanellus), the Musk Beetle (Aromia moschata), the Water Vole (Arvicola terrestris) and the Flowering Rush (Butomus umbellatus) are nowadays regarded as rare and declining species. They depend on wetlands such as these for their continued survival. The Great Silver Water Beetle (Hydrophilus piceus) is a very rare but magnificent aquatic insect that is known to occur in reens, ditches, ponds and lakes in this area.

I used to come to Marshfield and the Wentloog Levels as a boy. My father used to bring the family here in his car, and I well remember seeing millions of elvers, the young form of the now Critically Endangered European Eel (Anguilla anguilla) making their way up the reens and climbing and slithering in masses over obstructions caused by sluice gates regulating the water flow and depth. I also remember catching the Ten-Spined Stickleback (Pungitius pungitius) in the reens. They are still there today, I am pleased to report, as are the aquatic plants Frogbit (Hydrocharis morsus-ranae) and Arrowhead (Sagittaria sagittifolia), the first of which resembles a mini-water lily with rounded floating foliage, and the second plant gets its name from its arrow-shaped leaves. Both of these wildflowers have attractive white flowers, and it was good to see them again in the weedy drainage dykes.

The Seawall and Coastal Path

Seawall and mudflats (Photo: Steve Andrews)

The coastal path has a strong seawall that divides the reclaimed wetlands from the mudflats and tidal waters of the Severn Estuary. Here you will find large patches of saltmarsh, and I stopped to have a look in some of the shallow brackish creeks and muddy pools.

Here I saw plenty of small prawns, shrimps and the occasional crab. These crustaceans survive here waiting for the waters to be replenished by a high tide or rainfall. Interesting plants of the saltmarsh included Sea Lavender (Limonium vulgare) and Sea Arrowgrass (Triglochin maritimum).

Butterflies

On the grassy bank with the seawall at the top and a very long reen at the bottom there were very many Meadow Brown (Maniola jurtina) butterflies, and I was pleased to see this species seems to be still holding its own, while many other British butterflies are known to be declining fast.

Earlier on, I was glad to see evidence of Small Tortoiseshell (Aglais urticae) caterpillars that had spun a web over some nettles. The adults of this pretty butterfly were once very common all over the UK, but this is no longer the case. Another once common but now declining species is the Small Heath (Coenonympha pamphilus), and I was happy to see one of these whilst walking the coastal path.

Birds of the Gwent Levels

The Wentloog Levels and the saltmarsh of the estuary are ideal habitats for many birds. Reed warblers (Acrocephalus scirpaceus) and Common Reed Buntings (Emberiza schoeniclus) can often be heard singing and the abundant reed-beds of the wetlands are just what these little birds need. I heard and saw a pair of Skylarks (Alauda arvensis). This is yet another species that has been becoming a lot less in numbers throughout Britain, mainly due to habitat destruction and changes in farming.

Notice Board (Photo: Steve Andrews)

A notice board by the seawall called attention to some of the now rare bird species that make the saltmarsh their homes. The Curlew (Numenius arquata) and the Lapwing are two waders that can be found here.

Both were once common but both now have the Near Threatened conservation status. The notice board calls for "Respect for the locals" and asks people to keep dogs under control, and to stay off the saltmarsh where these birds feed and breed.

I saw another sign that showed that wildfowl shooting was once practiced here, and it was a grim reminder of another way we have lost so many birds.

Still common water-birds I encountered on my walk were Moorhens (Gallinula chloropus) and Coots (Fulica atra), swimming on the weedy waterways and ponds.

After many hours of enjoyable but tiring walking in the hot June sunshine, eventually, I found a pathway that led to a main road near the Lamby Way landfill tip on the outskirts of Cardiff. I thought it was interesting to see how nature was doing so well right next to this rubbish dump.

Save The Gwent Levels

Elsewhere, to the south of Newport, the Gwent Levels are threatened by a proposed motorway being built at fantastic cost, not just financially at an estimated £1.5 billion of taxpayers money, but to the very fragile ecosystem of the area it is intended to cut through. The road, if built, will go through five sites of special scientific interest or SSSIs. Welsh naturalist and TV personality Iolo Williams is one of many people trying to stop this madness. He describes the sites as “Jewels in the Welsh crown.” Find out more about the campaign to Save The Levels and help halt this before it is too late! Take action by supporting and spreading the word about CALM (Campaign Against the Levels Motorway).

Home Grown Exotics

Grow exotic houseplants from fruit and vegetables bought from the greengrocer

There are many fruit and vegetables we can easily buy at the greengrocer’s or the fruit and veg section of the local supermarket, that can be grown as unusual and exotic houseplants.

Pineapple flower

Homegrown Pineapples

The pineapple (Ananas comosus) is one of the best tropical fruits to try growing at home and with a bit of care it will even produce fruit.

I speak from experience, because many years ago when I was still living in Cardiff, I made the HTV News at Christmas with my homegrown pineapple. I was filmed watering my pineapple plant and talking about how I had cultivated it. I said I used soil from the back garden and water from the tap, and that I repotted it when the plant got too big for the pot it was in, but that was all I did. An expert from the Welsh National Botanical Centre praised my achievement, and I was proclaimed as the first Welsh pineapple grower.

All you need to do to follow my example, is to twist the spiky rosette part off from the top of a pineapple, and then remove the leaves at the base to leave a stump. Leave this to dry for a few days before planting by pushing gently into a pot of damp compost. If you are in luck, there may already be tiny roots sprouting from this stump before you plant it.

Once well-rooted the pineapple will grow into a large rosette of spiky leaves and after a few years, all going well, it will produce a flowering stalk right in the centre. Mine took five years to flower but that was in a house with no central heating in Wales! The tiny flowers are a pretty lavender shade and surrounded by reddish spiky bracts.

After the pineapple has ripened and been removed side shoots will form on the main stem. These can be removed for further pineapple propagation or if left on the original plant long enough, they can flower and produce a second crop. I managed to grow another pineapple like this.

Taro or Inhame

The taro (Colocasia esculenta)  is a root vegetable that is sold as “inhame” in Portugal, and “ñame” in Spain and the Canary Islands. The corms are cooked by baking, roasting or boiling, but what many people do not realise is that if planted these corms will produce a most attractive houseplant if given the chance. In fact, the taro is often grown as an ornamental plant known as “elephant’s ears.” It gets this name because it has large heart-shaped leaves.

Elephant's Ears

The taro likes a very damp compost and will grow submerged. You can often see these plants growing in fountains and water gardens. I have grown taro in a pot of compost I stood in a bucket of water.

Kiwifruit

You can grow kiwifruit (Actinidia deliciosa) vines from seeds from kiwis you have bought. It takes a long time for the plants to grow big enough to produce flowers and fruit but it can be done. I managed this when I was living in Wales still and followed up my pineapple story in the local media with my success at harvesting kiwifruit in my back garden. I admit it took five years before I had any fruit on my vines but I felt a real sense of achievement when I had my first crop of seven kiwifruit and my picture in the South Wales Echo. If I can grow kiwis in Cardiff, think how much better they would do here in Iberia!

Avocado

Avocado Tree

The avocado (Persea americana) is another fruit that can be easily grown. Just plant the large pits in a pot of compost and wait for them to sprout. Many people think you need special techniques for getting them to germinate but I have never found this to be the case. Simply burying a pit in a pot of damp soil has worked for me.  Your homegrown avocado will make an interesting houseplant when it is young and can be moved outside in Iberia when it gets bigger. Eventually it will form a large tree.

Ginger

Ginger

Another easy plant to grow is ginger (Zingiber officinale). This root vegetable is commonly used as a spice for curries and other hot dishes, and in herbal teas. Fresh ginger roots or rhizomes are easy to find in supermarkets. They will often start sprouting green shoots when in storage, almost as if they are inviting you to plant them!

All you need to do is to break off sections and plant them in a pot of compost. The shoots will take a few weeks to really sprout but will then keep growing into a plant with long narrow leaves. You can harvest your first crop of ginger later the same year, and fresh ginger you have grown yourself is so much fresher than the ginger you can buy.

There are many more fruits and vegetables that will grow from seeds, pips or roots of shop-bought produce.  Why not see what you can get to sprout? It can be a lot of fun finding out what can be grown and what the plants actually look like!

The Cacti of Iberia

Cacti of Spain and Portugal 

Prickly Pears (Opuntia dillenii)

You will see cacti growing in many parts of Iberia, mainly types of prickly pear cactus, and in some places, such as the Canary Islands, they are so common that it is easy to assume they are part of the native species. They look just right for the semi-desert landscapes. But in fact, there are no endemic cacti in Spain or Portugal, though some species from the Opuntia and Cylindropuntia genera have become widely naturalised. There are actually as many as 20 different types of Opuntia recorded as growing wild in Europe and the Mediterranean, but we are looking at the ones found in Iberia, and the ones you are most likely to see.

Prickly Pears

Harvested Prickly Pears

Cacti in the Opuntia genus are commonly and collectively known as prickly pears. The name refers to their edible fruit, which are found budding from the large and very prickly pads. These cacti have large numbers of tiny spines or glochids that project and will detach easily from the small bumps on the cactus skin that hold them, and which are technically known as aeroles.

There are two main species of prickly pear seen in Iberia: O. ficus-indica and O. dillenii. The first of these is known in English as the Indian fig Opuntia and the Barbary fig. The plant is referred to as “nopal” in Mexican Spanish, and its fruit is a “tuna.” The flowers are red, yellow or white, and the fruits are green, turning yellow or reddish as they ripen. It has been historically grown as a food crop for thousands of years in Mexico. You need to carefully remove the spines on the tunas by rubbing in an abrasive material and also peeling the fruit. They are usually eaten chilled and resemble watermelon in flavour. The fruit are also used to make jams and jellies, and have been used in the production of alcoholic drinks too. You will often see them for sale on fruit and vegetable counters.

The green pads, or nopales, can be eaten too. Again, you must carefully remove the spines, and the sliced pads can be fried or boiled.

Prickly Pear Flowers

The species O. dillenii is also known as O. stricta, and in English it is called the erect prickly pear. It has lemon-yellow flowers followed by purplish-red fruit with smooth skins, though, once again they are protected by spines. I used to eat a lot of these fresh when I lived in Tenerife, and used to manage to safely peel them using my thumb and finger-nails, but it is a tricky procedure so cannot be recommended. The tiny spines are notoriously difficult to get out of you and they hurt! This cactus is actually regarded as an invasive weed in many parts of the world where it has invaded the land. All species of prickly pear spread easily from pads which have broken off from the parent plant but which then root where they have fallen.

Cholla cacti

A very prickly Cholla

Speaking of cacti that spread easily from pieces that have become detached brings me to the cholla cacti in the Cylindropuntia genus. In Spain and Portugal there are two species that are commonly encountered: C. spinosior and C. imbricata. The first of these is known as the walkingstick cactus or the spiny cholla, and the latter species is called cane cholla or chain-link cactus. Both species are well-protected with large numbers of the most vicious spines imaginable all over the sections of the plants. The spines will easily break off, and the sections of cactus can also be readily detached. My advice is be very careful with these plants, because the spines are really painful. Fall accidentally into one of these and you will regret it!

The cholla cacti come from Mexico and the southern states of America but have spread to many parts of the world, where like the prickly pears, they have become invasive weeds.  Although these cacti can be problem plants, they also make formidable fences. Anyone caring to ignore them is asking for trouble!

Peruvian Apples

In addition to the cacti in the Opuntia and Cylindropuntia genera, you may see the Peruvian apple cactus (Cereus repandus/peruvianus) growing in gardens, and also on waste ground in Iberia. This cactus is very tall and produces columns that can easily reach as much as 10 metres in height. It comes from South America but stands up to cold periods in Spain and Portugal well. This cactus produces spectacular cream-coloured flowers that open at night and are only open for the one night. The flowers turn into edible fruit, known as Peruvian apples or pitaya.

Besides all these cacti that might be encountered in Iberia, many gardeners introduce other species into community-used ground near their homes, and cacti often root when they have been thrown out, so you can at times find all sorts of surprises but none are native plants. Gardeners in Portugal and Spain often grow many cacti outside that in the UK are strictly houseplants. The hot summers and mild winters give us an advantage when it comes to cactus growing.

The Endangered Trees of Sheffield and Other UK Cities

Save Sheffield's Trees

The endangered trees of Sheffield are a big concern for me, and a growing number of people from all walks of life. Not just local residents, but celebrities, such as Bianca Jagger and Jarvis Cocker, have joined the campaign to save the trees. Even Michael Gove, who is  Secretary of State for Environment, Food and Rural Affairs, spoke out and accused Sheffield City Council of committing “environmental vandalism.”

What is happening in Sheffield, where thousands of trees have been felled, is bad enough but it is happening in many other UK cities too. Cardiff, Swansea, Liverpool, Birmingham, Bristol, Brighton, and London, are some of the ones I have heard of where trees are being so needlessly felled. I keep hearing of more places where trees are under threat or have been destroyed. A report in The Guardian, states that, over the last three years, as many as 8,414 trees were felled in Newcastle, 4,778 were removed in the county of Wiltshire, and a massive 4,435 got the chop in Edinburgh. The more I have got involved in the battle to save Britain’s city street trees, the more I have found out, and the more concerned I have become.

As it is, I often worry about what is happening to the countryside and wildlife of the UK. I keep reading of the declining numbers of so many species of flora and fauna, and sadly it doesn’t surprise me. The habitats animals and plants need are rapidly being destroyed. Among these habitats are forests, and now city trees are in danger too, and many have already been lost. City trees provide homes for wildlife, nesting and roosting places for birds, food for caterpillars of moths and butterflies, and nectar for bees. City trees help to clean the air, as well as providing the natural beauty of their greenery.

In Sheffield, there was the threat to a surviving elm tree and an entire colony of the endangered white letter hairstreak it supports. This little butterfly has caterpillars that can only feed on elms. After much protest about this potential eco-crime, there was even talk of relocation efforts and a scheme in which butterfly eggs were going to be looked for an moved to other elms. I was not alone in not having much faith in this plan working.

So why is this destruction of British trees happening? Making money and saving money appears to be the answer. Development companies make money by destroying what is there and putting something new in its place. Corrupt city councils save money by not having to pay for the maintenance of established trees. It is much easier to maintain a road with no trees or few trees than one with lines of mature trees. It is much easier to say trees are being replaced, and then plant some saplings, many of which will actually die. It is easy for city councillors to say they care about the health of residents and that they want to see a green city and improve air quality for the future, but then take actions which betray their words, which are just political lies.

The story of Sheffield’s trees is a tragic one. Its main players are Labour councillors and Amey plc versus campaigners who are doing all they can to stop mature and healthy trees from being killed and removed. Police and security forces have been called in to enable the tree killers from Amey to be able to get on with their destructive work.  Bizarre but true news stories have been reported, for example, of over 30 police on duty to enable one tree to be chopped down. The situation has become so crazy it is almost unbelievable, almost surreal. A woman protester was arrested for playing a toy trumpet and a priest for playing a tambourine! Campaigners, who are the true heroes and heroines when it comes to the plight of Sheffield’s trees and efforts to save them, are treated as criminals and ending up in court, while the true crooks walk free.

The public have been lied to by politicians that claim to care about their communities, and many people have learned from this that Labour councillors they voted for did not live up to their image, and were no better than their Tory counterparts after all.

The tree-felling in Sheffield has got worse and worse with respect to how the public have been treated. It has got so bad that not only are protesters being arrested on nonsensical charges by heavy-handed police but operations to fell the trees are being carried out under cover of darkness and several trees have already been killed this way.

Save Roath Trees

It was in Cardiff that I first got involved when I went along to the parks in Roath where trees along Roath Brook had been felled or marked for future felling. Here it was not Amey plc to blame for the destruction but Natural Resources Wales, that had approved a flood defense scheme, even though there had been no flooding. Residents were rightly annoyed and saddened to see trees that provided part of the beauty of the park, and homes for wildlife, being callously marked as targets for removal. Roath Brook supports all sorts of wildlife, including kingfishers, and there have been reports of the endangered water vole living here too.

Disappearing Trees of Roath (Photo: Steve Andrews)

This haven for wildlife is not far from bustling city streets and should surely be looked after and treasured? Removing a large number of its varied tree species can only damage the site. To find that an organisation, supposedly in charge of looking after the Welsh environment was backing this eco-vandalism is shocking. But perhaps not if we think about what the word “Resources” means to these people. To my mind, this is where a great deal of the world’s problems have their source. The natural world is so often viewed as “resources”, that can be bought and sold, resources that can be used or abused by people, who so arrogantly think themselves superior to nature, not part of it and dependent on it.

Fortunately, the ‘work’ in Cardiff has been put on temporary hold, but it is by no means a victory for campaigners yet, and elsewhere in the city other trees and wildlife habitats are under threat. Redrow plc/Redrow Homes is a housing construction company that have started work on the Plasdwr development project, covered in another of my blogs. Campaigners in Liverpool are hoping to stop this company from destroying trees and parkland at Harthill and Calderstones Park.

Redrow Danger Sign (Photo: Steve Andrews)

I actually had a tweet from someone at Redrow after I had been talking about these matters at Twitter: "Hi Steve. We are translocating existing hedgerows as well as planting new native trees at our PlasDwr development. We are currently developing a new biodiversity strategy which focuses on ensuring net gains for biodiversity on our developments.  Kind regards, Nicola" My response to this was asking how can destroying established trees help ensure biodiversity when it destroys existing habitats and species that depend on them, and pointing out new trees take a long time to grow to the size of those replaced. It remains unanswered.

Stand By Tree

Singing and standing by Tree

So what can we do to help save our trees? My answer, as a singer-songwriter and performer was to sing about it. I changed the lyrics of Stand By Me to “Stand By Tree,” and “All we are saying is give peace a chance” to “All we are saying is give TREES a chance.” And also I have changed the lyrics to "Everybody's talking 'bout Jarvis Cocker, he's a rocker, celebrities, saving trees. All we are saying..."

I have been active on social media reporting on the subject of the protest campaigns to save the trees of the UK. I was made into a poster-boy for the campaigns and was interviewed by Jonathan Downes for his GONZO Weekly too.

Other activists have held public demonstrations or put themselves in the way of the tree-fellers. Many have signed petitions, and like myself, used the social media and news-media to have their say. Some brave but unlucky protesters, including poet, singer and musician Benoit Benz Compin, have found themselves under arrest. But we must carry on doing whatever we can.

I am writing a new song and it contains the lines:

"Who will stop the destruction of so many trees?
Who will save the birds, the butterflies, and bees?
It comes down to the protesters,
To campaigners, like you and I,
We cannot let them kill our world,
We cannot let it die."
