Salisbury Wildlife and the Avon Valley Nature Reserve

Visiting Salisbury


I recently had the pleasure of visiting the city of Salisbury in Wiltshire for a few days and fell in love with the place. I was happy to see that wildlife is thriving here, despite increasing declines in species throughout much of the UK.

Even in the heart of the city I spotted Cinnabar Moth (Tyria jacobaeae) caterpillars on Ragwort. There were plenty of these brightly-coloured caterpillars on plants growing on the riverbank right by the Waitrose supermarket. These larvae have orange bodies, banded with black rings. The adult moth is also a very pretty creature with red and black wings. It flies by day and could easily be thought to be a butterfly. This moths caterpillars eat various species of Ragwort and Groundsel (Senecio species). Although these plants are classed as weeds they are very important sources of life for many additional species, in addition to the caterpillars of the Cinnabar Moth. The Buglife charity, which is concerned with the conservation of invertebrates, has reported that over 30 other species of insect depend on Ragwort alone.




Avon Valley Local Nature Reserve

I was in Britain for Summer Solstice at Stonehenge and also visiting my friends, author Chris Stone, and Druid and eco-warrior King Arthur Pendragon and his partner Kazz. Arthur and Kazz live locally and they suggested we could go on a walk in the nature reserve that is on the banks of the River Avon. I love nature, so was happy to agree to their suggestion, and was very highly impressed with what I saw.

The River Avon looked really clean and there were very many fish that could easily be seen swimming in the current. I spotted Brown Trout (Salmo trutta), Minnows (Phoxinus phoxinus), and what looked like Dace (Leuciscus leuciscus).

Meadowsweet (Photo: Steve Andrews)


There are extensive water meadows bordering the river too, and in the marshy ground was plenty of Meadowsweet (Filipendula ulmaria) in bloom. It has a most amazing perfume that reminds of summer meadows and freshly mown grass, and is a most beautiful herb that is actually in the rose family (Rosaceae).



As well as Meadowsweet, there  were plenty of Creeping Thistles (Cirsium arvense) in flower, and also the very poisonous, but attractive to insect pollinators, Hemlock Water Dropwort (Oenanthe crocata). Kazz spotted a colourful moth feeding on the nectar from this dangerous plant, and she asked me what it was. It was a Scarlet Tiger Moth (Callimorpha dominula), a pretty moth that flies by day, and is of interest because it is unusual for being able to feed. Most other species of tiger moths have no mouth-parts and do all their feeding as larvae.

On the thistles I saw several Small Tortoiseshell (Aglais urticae) butterflies. This was a good sign because this once common species has been declining fast in the UK over the past few years. There were plenty of clumps of Stinging Nettle (Urtica dioica) growing nearby, and this is its main food-plant for its caterpillars.

Water Voles

Near a bridge over the Avon there was an information board showing species of wildlife that can be found on the reserve. I was happy to see the Water Vole (Arvicola amphibious) included. This is a British mammal that has become increasingly rare, so it was very good news to see that it is holding its own here. Kingfishers (Alcedo atthis) too frequent the area I learned, and I was not surprised, because it is an ideal habitat with plenty of small fish they can hunt.




Elsewhere in Salisbury

 I also went for an evening stroll with Chris around Salisbury and around the area outside Salisbury Cathedral. The atmosphere was calm and peaceful and it was a glorious summer evening. I was really impressed with how there was no litter to be seen, no graffiti, and no damage to trees of the city, unlike elsewhere in the UK, where trees are being felled with the support of local councils. How is it that Salisbury doesn’t appear to have the problems other towns and cities have I wondered? “I would love to live in Salisbury,” I told Chris. “I think you will find properties here are very expensive,” he told me. He also pointed out that Salisbury is a Tory stronghold, and suggested that might have something to do with how it is there. He was right that houses and flats in the city are very expensive to buy and rent, and also that the Conservative party is in power there.

In no way do I support the Tories, but it got me thinking about how it seems that it is mostly Labour councils that are behind the destruction of so many city trees in Britain. For example, this is the case in Sheffield, a city that has made world news with regard to the thousands of trees that have been felled there by Amey Plc with the support of Labour politicians. I haven’t done the research yet but I wonder how many cities have lost their street trees due to corrupt Labour councillors?

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

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.

Coot (Photo: Steve Andrews)

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!

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.
