SAVE THE FROGS DAY 2022 Report from Portugal

 Special report from Quinta do Conde for SAVE THE FROGS Day! 

With my friend, fellow singer-songwriter Ana Lisa Meier, for this year's SAVE THE FROGS Day, we decided to create a report about frogs and wetlands in the Quinta do Conde area of Portugal where we are. Ana is very lucky because she has a colony of Iberian Water Frogs in her garden. They live in, and around, the two garden ponds, which shows how valuable ponds like this are when it comes to amphibian conservation.  Here I am enjoying listening to the frogs and the birds singing.

We went to explore the wetland areas near where we live, took some photos and captured some video footage there. There is an area of wetland behind a sports stadium that depends on a lot of winter and spring rainfall to be of any use to amphibians. This year the rains came very late, after a winter drought, presumably due to the Climate Crisis. The water sadly drains away fast and feeds a river nearby, as well as being absorbed by the sandy ground. I feel this area could be greatly improved as a wetland habitat if some restoration work was done there so that the water was retained longer. 

We went to look at the river, which some years gets nearly dried up, although there are usually some pools left standing. Frogs can be found here and at this time of year you can hear Iberian Water Frogs singing, though they are very difficult to spot. 
 

I once saw a European Pond Tortoise here too. I wasn't able to get a photo because it dived in the water. This species is endangered, so I was pleased to see that at least one was surviving in a wildlife habitat near where I live.  Further along this river there is a bridge and the frogs can be heard loudly there, although we were unable to actually see any. They stop calling when you approach. 
Sadly right by this bridge we encountered some highly polluted water from a drain entering the river. This is really bad because this river feeds an Ecology Park further along its course.  Water pollution is a serious threat to amphibians, fish and other wildlife. 
Back by the stadium and right by a main road are a lot of temporary pools that fill up in winter and spring and are always used by local amphibians. Tadpoles can be seen in the cloudy water but it is always a race against time for them because the pools always dry up, leaving just cracked mud until next rainy season. making the situation worse, people enjoy driving through these pools. I once saw a vehicle stuck in one of them with the mud flying up. I must admit I thought it was funny and had no sympathy for the driver. It was as if this was "Instant karma."
 
Ana and I next went to take a look around the Ecology Park of Quinta do Conde, a place I have written about before in this blog. There is a small lake there and when I last visited, it was full of water and there were plenty of frogs about. Sadly this was not the case this time, though Ana spotted one tadpole. The water was very low and we discovered yet another source of pollution because there was oil floating on the surface at one end of the lake and a trickle of oily water entering it there. Someone had thrown a shopping trolley into the water and a landing stage for visitors to stand on to get a better look over the water had been demolished for some reason. 
 

The Ecology Park was showing neglect and was disappointing, although there are extensive reed beds there, and many other smaller pools and dykes in an area used for allotments that local people grow fruit and vegetables in. Because the water was so low in the lake I thought that Herons and Storks had probably caught a lot of the frogs and any fish that live there. Storks congregate in the fields next to the park, and Herons are also seen here. Storks and Herons, of course, have to find food, and are just as important as frogs. Although our visit to this park was somewhat disappointing, it fitted in with what we were trying to do, which was to conduct an exploration of our neighbourhood, to keep things local. I think it is important for anyone who wants to help with conservation of amphibians and other species of wildlife, to do what you can in the area you live in. This applies wherever you are in the world. If you have found this report interesting and would like to find out more about what you can do to help SAVE THE FROGS, please visit the SAVE THE FROGS website! Now I'm off to help SAVE THE FROGS!

The Ecological Park Varzea in Quinta Do Conde in Portugal

A lot more to the town of Quinta Do Conde
Map of the Ecological Park (Photo: Steve Andrews)
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.
Turtle Lake and White Storks

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.

Pussy Willow (Photo: Steve Andrews)
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!

Walking in the Wentloog Levels Where Wetlands Meet the Sea

Wentloog Levels aka the Gwent Levels are a Wildlife Haven

Marshfield (Photo: Steve Andrews)

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.

Small Tortoiseshell caterpillar web (Photo: Steve Andrews)

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.

Saltmarsh (Photo: Steve Andrews)

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.

Private Shooting sign (Photo: Steve Andrews)

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! Take action by supporting and spreading the word about CALM (Campaign Against the Levels Motorway).

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 Second Pond (Photo: Steve Andrews)

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.

Habitat created for Great Crested Newts (Photo: Steve Andrews)

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.

Aquatic plants (Photo: Steve Andrews)

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.

Info board (Photo: Steve Andrews)

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.

Cuckoo Flowers (Photo: Steve Andrews)

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.
