The Ecological Park Varzea in Quinta Do Conde in Portugal

A lot more to the town of Quinta Do Conde

If you were driving through on the main road through the town of Quinta do Conde in Portugal you might not think there was much to see there. You might think it was merely a typical Portuguese town with plenty of houses, apartment blocks, local businesses, a share of restaurants and bars, as well as shops, roads, and all the usual urban ingredients.  A pleasant enough place if you lived or worked there perhaps, but not a lot else there, and not much to see. However, you would be very wrong. If you are interested in nature, ecology and gardening, Quinta Do Conde has an amazing Ecological Park known as the Parque Ecológico da Várzea da Quinta do Conde. This park is actually right next to the main road, and just minutes from the busy local Continente and Pingo Doce supermarkets, but it is a real haven for wildlife, a wonderful place for relaxing, and it even has an allotment area where local people can grow fruit and vegetables.

The Ecological Park has a lake known as Lagoa Cagados, which means Turtle Lake in Portuguese and presumably refers to freshwater terrapins that can be found there. I didn’t see any any when I visited but I did see a number of frogs jumping into the water. They were Iberian Water Frogs, a species that is common here. There is a large area of swampy meadow where I have seen flocks of White Storks gather. They are easy to see from the main road and I have noticed them on my way to the shops. I expect these large birds are hunting frogs that are plentiful in the park. I saw more of these amphibians in a reedy pool but the creatures were too quick for me to get any photos.

According to an information plaque, Grey Herons also frequent the wetlands provided here. I am not surprised because there are many ponds, water canals and reed-beds. In one part there is a lookout point for birdwatchers.

Walking Areas
There is a system of paths and walking routes around the park, as well as areas with tables and benches where you could relax or enjoy a picnic. I was impressed with the number of small birds I saw and heard in the park, and also there were plenty of honeybees collecting nectar from the catkins of the Sallows, or “Pussy Willows” as I also know them.

I noticed a lot of Fennel sprouting amongst the greenery, and this plant is eaten by the caterpillars of the Swallowtail Butterfly, which breeds in the park. I found a clump of Salad Burnet too, which is another edible herb.

Woodlands
There are plenty of trees and woodland areas in the Ecological Park and many of the trees are labelled. I saw an Alder covered in catkins, and there are also Cork Oaks, Pines, and at least one Strawberry Tree. In one part of woodland I noticed a large pile of rocks. It had been fenced off and I wondered if this was intended as a place for reptiles and amphibians to shelter and hibernate in winter. It would make a great place for this. According to an information board I saw, the Viperine and Ladder Snake can be found there, as can Fire Salamanders and the Common Toad. I would not be at all surprised. It is simply a wonderful location for wildlife of most types.

The Allotments

Continuing my walk around the grounds of the Varzea Ecological Park of Quinta Do Conde, I had a look at the area given over to allotments. This area is very much for wildlife as well as people, and I noticed nest-boxes were in use to encourage nesting birds.

Here in the allotment section, local gardeners grow cabbages, kale, onions, leeks and many other vegetables.
Vegetable Plot (Photo: Steve Andrews)
The plants all looked very green and healthy, and the plots of ground are watered with water from the ponds and water channels. These pools and areas of freshwater provide further areas for aquatic life, amphibians and water birds, and I could see thousands of the Mosquito Fish (Gambusia holbrooki) in one of the larger ponds. This is a fish I was used to seeing in Tenerife when I lived there some years ago. Mosquito Fish have become naturalised in many subtropical parts of the world where they were originally brought, as their name suggests, in an effort to control mosquitoes. These little fish are very adaptable and can tolerate high and low temperatures, polluted and brackish water.

I saw a few dragonflies too and would think the park would have loads of these insects later in the year. I am lucky to have this park near to where I live so will be making many more visits and seeing what goes on there in spring and summer. I imagine the ponds will have a loud chorus of frogs and plenty of tadpoles will be swimming in the water. I love the sound of frogs croaking!

How A Council Estate Like Ely Can Be A Haven For Wildlife

Gardens in Ely

The Ely council estate in Cardiff can be a great place for wildlife as I found out when I lived there for 24 years. The gardens attract a lot of birds, butterflies, moths, amphibians, and at least one reptile, which is the Slow-worm. "Slowgies" the local kids used to call them. This legless lizard was very common in gardens and you even saw them in the streets at times. They are no longer so commonly found in Britain.

Many of the species that can be found in Ely are now recognised as being in an alarming decline in the UK, so anywhere they are still thriving is important as a conservation area. Anyone who is actively helping these creatures is doing a great job in helping preserve the world of nature. Gardens can easily become mini nature reserves! You just need to grow some wildflowers, leave some parts untended, and a garden pond always works wonders! A Buddleia Butterfly Bush will help attract these pretty insects and other pollinators as well.

When I lived in Ely, I had a makeshift pond I created from an old bath that had been thrown out. I sunk it in the ground in the back garden and within a couple of years it supported a colony of Common Frogs as well as Palmate Newts.

I know Common Toads could be found fairly near where I lived too because a man I knew called Graham used to complain about male toads strangling his goldfish, which can happen. The unattached male toads will grab onto anything they think might be a female of their species.

The Common Toad is one amphibian that is known to be experiencing a decline in Britain and elsewhere. All amphibians are under threat worldwide though, due to loss of habitat, pesticides and herbicides, pollution, invasive species that predate on them, and Climate Change. I am proud to be a member of SAVE THE FROGS! Charity set up to help these creatures.

One of the last times I was in Ely I went to visit Parker Place the street I used to live in and was saddened to see that what used to be my front and back garden had been ruined by the Council workers, who had removed the hedge, tree, lawns and flower borders in the front, as well as the Virginia Creepers I had growing on the wall. In the back my pond had gone, as had trees I had been growing for the many years I was there, as well as a grape vine that used to attract flocks of starlings, as well as blackbirds that used to eat the fruit each year. My nettle patch for butterflies had, perhaps not surprisingly, also been removed. It was very sad to see how all my work in helping wildlife had been wrecked but I was heartened to find that Jess, who had been my neighbour, was still there and she told me she now had a pool in her back garden. It was good to know I had helped inspire this!

Moths and Butterflies

Garden Tiger Moth (Photo: Pixabay)
It is a well-known fact that many species of British butterfly and moth have been doing very badly in recent years. Once common species, such as the pretty Small Tortoiseshell Butterfly and the large and gaudy Garden Tiger Moth are no longer commonly seen.
Small Tortoiseshell (Photo: Pixabay)
They need all the help they can get. I used to have Small Tortoiseshell and Red Admiral caterpillars on a patch of Stinging Nettles I had growing at the bottom of my garden. I also had Painted Lady larvae feeding on Hollyhocks I had growing in the back and front. Garden Tiger Moths needed no help then and I often saw the large furry “Wooly Bear” caterpillars and the striking orange, creamy-white and chocolate-brown moths with dark blue-black spots on their hind-wings.


Cinnabar Moth (Photo: Pixabay)
The attractive day-flying Cinnabar Moth with red and black wings and orange caterpillars striped with rings of black were a common sight. They feed on Ragwort and Groundsel, both of which were common weeds. The Cinnabar has been declining as well over the past decade. I also remember having Comma Butterfly caterpillars one year on my gooseberry bushes, and Common Blue butterflies used to frequent the front lawn of one of my neighbours, who had Bird’s-foot Trefoil growing in the grass. Now I live in Portugal I often see the same species doing well on lawns between housing blocks in built-up areas. The reason being they find trefoils, clovers and Sorrel (Oxalis species) growing amongst the grass. Butterflies need food-plants for their caterpillars and nectar from flowers for their adult stage. If we supply both we will probably attract butterflies to our gardens.

Are all the species I have mentioned still to be found in Ely? I don’t know because I no longer live there but if they are, then residents of the estate can help them survive and can have something to be proud of. I am sure there must be lots of people in this vast estate who are interested in nature. Perhaps a local group could be set up? Ely is also surrounded by some excellent countryside for wildlife, with Plymouth Woods being a deciduous forest that used to have a pond and marshy area. I know frogs and newts used to live there and many birds are attracted to the wooded parts and undergrowth. Ely is an example of a council housing estate that I know, and that I also know could make a great contribution towards nature conservation. The same conceivably goes for all the other estates in the UK.

Young people need to learn about the wonders of the natural world. It gives them something to take a real interest in, and interest that can stay with them for life. All the famous naturalists, like Sir David Attenborough and Chris Packham, began learning about nature when they were children. I started when I was four! I hope this article encourages more people to learn about plants and animals living on their doorsteps, so to speak, and most importantly to help conserve the natural world by making their gardens wildlife friendly.

Here Be Dragons

The Mysterious Dragon Tree Produces Dragon's Blood


Dragon Tree (Photo: Pixabay)

The dragon tree (Dracaena draco) is a very weird-looking plant that grows to the size of a tree and can live a very long time. One known as the “Drago Milenario,”  that grows in Icod de los Vinos in Tenerife, is said to be 1000-years-old or more, though other estimates put it at more like 650 years.

Dragon's Blood

The dragon’s tree is the source of a resinous substance known as dragon’s blood, which is formed when the tree is cut. The sap that oozes out dries a dark red colour. Dragon’s blood is said to have magical and medicinal properties. It has been used in varnish and also as an ingredient in incense.

Dragon trees are native to the Canary Islands, Cape Verde and Madeira but are very rare in the wild, though extensively planted in parks, gardens, and public squares. Having lived in Tenerife for many years, I was used to seeing them around the island, so was very pleasantly surprised to find specimens of the dragon tree growing well here in Iberia too. I have seen them in Gibraltar and there are some rather splendid examples in the botanical gardens of the University of Lisbon. The dragon tree has also been introduced to the Azores.


The dragon tree grows very slowly and can take around 10 years just to reach 1 metre in height. It can flower for the first time then but will not branch until it has flowered. Each branch then takes a long time before it flowers and branches again. As this process continues the dragon tree produces a characteristic umbrella or mushroom-shaped crown of branches. Dragon trees produce spikes of perfumed whitish flowers which develop into orange-red berries, each one containing one or two very hard and almost globular seeds.

Dragon Tree Berries (Photo: Steve Andrews)

The dragon tree seed takes a month or even longer to germinate from seed and first of all produces a rosette of spiky and leathery evergreen leaves. The silvery and scarred trunk gets formed as the plant grows bigger and the lower leaves die and get removed.
The lower branches produce aerial roots which hang down and have been likened to a dragon’s beard. These roots can fuse with the trunk as they descend and reach the soil and in this way very broad and curious-looking trunks get formed in very old specimens.
Dragon trees are monocotyledons in the Asparagaceae or asparagus family, and do not produce annual rings inside their trunks. Because counting these rings is the usual way of discovering the age of a tree, it is very hard to work out how old a dragon tree actually is. It is done by counting the branching points and estimating how long it has taken to form these.
La Orotava Dragon Tree (Photo: Public Domain)

There was once an enormous dragon tree in La Orotava in Tenerife that was even bigger and older than the Drago Milenario, mentioned earlier. The naturalist and explorer Alexander von Humboldt was amazed when he saw its height and girth. This dragon tree was 70 feet (21 m) tall and 45 feet (14 m) in circumference, and was believed to be 6000 years old. It was destroyed by gales in a terrible storm in 1868.

In Greek Mythology

Not surprisingly there is much folklore and myth built up about this strange tree, and the story goes that the first dragon trees grew when the legendary hero Hercules of Greek mythology killed the hundred-headed dragon Ladon, who was guarding the Garden of the Hesperides. Where the blood of the monster fell little dragon trees sprouted.
Dragon trees are easy enough to grow from seed but you need a lot of patience to wait for them to germinate and to produce much growth, although this plant will make a very interesting houseplant when young and a wonderful addition to the subtropical garden when bigger. They are drought resistant, and in the wild they often grow on rocky hillsides and cliffs.
Ready-grown dragon trees are sometimes available from gardening centres and ornamental plant suppliers and buying one this way could be the easier option for getting hold of one. However you get your own dragon tree, it will certainly make a great talking point, and the plant could still be alive hundreds, and maybe thousands of years, from now!

Forest Farm and Glamorganshire Canal are Great Places for Nature

Forest Farm Reserve and the Glamorganshire Canal


Photo: Steve Andrews

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.

Why Tenerife is a paradise for naturalists

Tenerife is a naturalist’s dream
Tenerife forested mountains
Tenerife is a popular island in the Canary Islands for tourists who spend their holidays there but it is also every naturalist’s dream. With its forests, mountains, semi-desert areas, cliffs, sand dunes and range of beaches there is a real diversity of habitats. There are so many types of countryside on the island, and also a range of very different microclimates. This is why so many forms of flora and fauna can be found there, both endemic species and introduced and naturalised plants and animals.
Laurel Pigeon (Photo: DrPhilipLehmann)
There are two main sorts of forests: pine forest and ancient evergreen laurel forest. The latter of these is very important because the patches of this type of woodland that still stand on Tenerife and some of the other Canary Islands are some of the only remaining stretches of this form of forest in the world. Rare birds, such as the laurel pigeon (Columba junoniae) and endemic plants like the Canary Islands foxglove (Isoplexis canariensis) can be found in the laurel forests.

Viper's Bugloss species

Red Bugloss
Tenerife has a very great range of species in the Echium genus of viper’s bugloss. The most spectacular species is the red bugloss or Teide bugloss (Echium wildpretii), which as its name suggests has red flowers that form in tall spikes, and it is found growing high on Mt Teide where there is a very extreme habitat. Because it is so high the sunlight is very strong but it gets very cold at night. The ground is dry and rocky and it looks like another planet in the Tenerife highlands.
There is a shortage of naturally occurring freshwater in Tenerife because it drains quickly into the ground and down to the sea after it rains but this has not prevented a fascinating selection of freshwater creatures and water birds being found on the island. Many species of dragonfly, two species of frog and the mosquito fish (Gambusia affinis) mainly depend on the reservoirs and irrigation tanks used by farmers for collecting water for their crops. The frogs, by the way, are the Mediterranean tree-frog (Hyla meridionalis), and the Iberian water frog (Rana perezii). In the village of Erjos, however, there are some large ponds that formed after the topsoil was removed many years ago. These pools attracted all sorts of wildlife and make a wonderful area for appreciating nature and walking in the surrounding hills and forests. 
Grey Heron
The grey heron (Ardea cinerea) is a bird that uses natural and artificial freshwater pools to search for fish and frogs and is often seen on the island. It will also take goldfish from ornamental ponds in parks and gardens.
Tenerife has lizard species, two types of gecko and a skink but no snakes, despite having excellent habitats for these reptiles.
Monarch butterfly
There are many interesting insects to be found on the island. A butterfly to look out for is the monarch (Danaus plexippus). It was able to colonise the Canary Islands because the tropical milkweed (Asclepias curassavica) is often grown in gardens, flower borders and parks. This large and beautiful butterfly can be seen flying all year round and is most often seen in cities, towns and resorts where its caterpillar’s food-plant grows in gardens. The massive and strange looking death’s head hawk moth and its larva are often found on Tenerife. This moth gets its name due to the skull-like marking on its thorax. The fact that it can squeak too has added to its weirdness and has made it the subject of various superstitions. The caterpillars are very big and feed mostly on thorn-apple (Datura stramonium), which is a very common weed on the island, and also on the shrub Lantana (Lantana camara).  There are also some species of praying mantis that can be found on Tenerife.
Mantis
Botanists will be excited by the very large number of succulents that grow wild on Tenerife. There are many endemic species of Aeonium and Euphorbia. The Canary Island spurge (Euphorbia canariensis) looks more like a cactus and grows in large clumps on arid and rocky ground around the island.

Look out too for the prehistoric-looking dragon trees (Dracaena draco), which can still be found occasionally growing wild but are very rare. They are much more commonly seen in parks and gardens around Tenerife, and there is the famous “Drago Milenario,” said to be 1,000-years-old that is in its own park in Icod de los Vinos.

If you are interested in wildlife you will find plenty to interest you wherever you are on the island.

The Ladder Snake is aptly named because of the ladder markings on its back

Ladder snake (Elaphe scalaris) Photo by Pascal Dubois




The ladder snake (Rhinechis scalaris) is an attractive harmless snake found in Portugal, Spain, southern France and some parts of Italy. It is also found on Menorca but is thought to have been introduced there. 

The ladder snake is in a group of snakes known as “rat snakes” because they have a tendency to feed on rodents. It is also known as Elaphe scalaris, which is the genus the other rat snakes are in.
The ladder snake takes its name from the dark markings between two blackish parallel lines down its spine that look like the rungs of a ladder. 

The ladder snake is more highly coloured when young when this patterning really stands out.  These juvenile snakes are a yellowish or pale brown in colour with the ladder marking in a contrasting black. There are dark markings on the sides and belly of these snakes too but the colours fade as they grow older.

Young Ladder Snake Photo by Steve Andrews


Adult ladder snakes reach around 160 cm and are mainly a dark brown or greyish for their main colouration.

Ladder snakes can be found in a variety of habitats, including scrub-land, clearings in forests, orchards and vineyards. These reptiles also have a liking for stone walls in which they can hide and hunt their prey. They also frequent rocky ground where there are plenty of boulders.

Ladder snakes feed on mice, shrews, small rats, birds, lizards, spiders and some other insects. Young snakes take small lizards and baby rodents, and also have a liking for spiders and grasshoppers. Adult ladder snakes will hunt birds in their nests by climbing into bushes and trees. Ladder snakes are active by day and night. 

Female ladder snakes lay between four and 24 eggs. The mother snakes will remain with the baby ladder snakes for a few days.

The ladder snake is in the Colubridae family of snakes, many of which are also non-venomous. The ladder snake will bite in defence, however, and will hiss if captured.

Because the ladder snake has a very wide distribution and lives in many habitats it is not regarded as in any current danger. Its conservation status is of Least Concern. Some ladder snakes become road casualties though, and the danger of getting run over by traffic is serious threat to many other types of reptile and amphibian.
