Adrian Lloyd Jones: Return of the Beaver

This was a fascinating talk giving us a real insight into these wonderful creatures and an understanding of how nearly they were taken to extinction by man's hunting

With the aid of some props we really had an insight into how these creatures live and how close to the riverbank they are confined in their lifestyle

I had not realised how far the considerations of doing a managed release in Wales had moved forward so it was really interesting to hear about the work of the Welsh Beaver Project http://www.welshbeaverproject.org/home/


Adrian gave us the link for all the detailed documents that show the net benefits to wildlife, environment, and especially flood prevention http://www.welshbeaverproject.org/downloads/ and went through us the net benefits and the very few considerations that need to be taken into account and showed how easily these are dealt with

He also talked to us about the less reputable side of introductions (Beaver Bombing) which was something many of us were unaware of and a bit of research today turns up this upsetting article on National Geographic http://news.nationalgeographic.com/news/2014/08/140804-beavers-science-environment-britain-extinct-animals/ From reading that I can see how much education is needed of people to understand that the Beaver Dams will reduce not cause flooding. It's also clear from the comments that you need to be careful dealing with reporters from any publication as there is a need to clarify the article so read down for all the facts (and some opinions)

At the end of the talk we did a straw poll on the opinion of the audience as to whether we are in support of the project and I am pleased to say we agreed 100% with the proposal and we would be really happy to see it go ahead

Report on Sally Snow's whale shark lecture

 
Sally took time out of her busy schedule to give the Cardiff Naturalists’ Society a fascinating, entertaining, and very informative talk about the whale shark (Rhincodon typus) and the work she has been involved in with the Large Marine Vertebrate project (LAMAVE), an initiative of the NGO Physalus, in the Philippines. The talk on Monday 13 Oct was illustrated with spectacular images by LAMAVE photographer Steve De Neef. Sally was accompanied by Dr Alessandro Ponzo, the President of Physalus and her partner, who kindly took the group photo above.

Whale sharks can be individually identified by their unique pattern of spots. Sally explained how an area on the left side behind the head is photographed, and a computer algorithm used to confirm an individual’s identity compared with a database of whale shark images. To date, over 700 individuals have been identified from photographs. This relatively cheap technique has advanced the study of the shark’s behaviour. Whale sharks can swim considerable distances; satellite tracking of tagged sharks have revealed journeys of over 5,000 km in Asia. Combined with biopsy data, we now know there are no isolated populations of whale shark – genetically they mix across the globe.


The whale shark can grow up to 20 metres long and live for over 50 years. They are filter feeders and capable of deep dives. The biodiverse seas around the Philippines are a vital habitat for the species and they are known to give birth there. They are now protected in the Philippines, though not in other the seas off neighbouring countries, with bans on catching whale shark been put into place relatively recently. They are now being exploited in a new way: tourism.

Sally emphasised that not all wildlife tourism is eco-tourism, in fact most is not. There are four areas where tourists are taken out in boats to see whale sharks in the Philippines. She contrasted whale shark tours in Oslob, where guidelines are not enforced, with an eco-tourism operation in Leyte that LAMAVE is helping operate. In Oslob, the whale sharks are crowded by too many boats and are approached too closely by divers; over 2,000 people can be in the vicinity of the sharks in a five-hour period. In Leyte, strict rules are enforced on how to approach whale sharks to minimise disturbance.

Commercial whale shark tourism operations are now provisioning – artificially feeding the whale sharks from boats to facilitate tourism. The LAMAVE team’s scientific data is showing that this can affect the sharks’ behaviour in an adverse way. They do not provision in Leyte and Physalus recommend that provisioning be stopped. Eco-tourism when carried out in a responsible manner, however, provides an alternative local source of income, can benefit conservation if environmental fees are charged, and can have a beneficial educational role.

Next Indoor Meeting, on 13 Oct: Sally Snow on Whale Sharks

At the next indoor meeting of the CNS, on Monday 13 October, Sally Snow will talk about 'The world's largest fish: an introduction to the whale sharks of the Philippines'.

The meeting will be held in Room 0.23 (ground floor) at the Cardiff School of Management, Llandaff campus, Metropolitan University, Western Ave, Cardiff.

Sally Snow was born in west Wales. She grew up sharing a house with wildlife, because both her parents were also Doctors of Zoology. Sally studied Zoology and Psychology at Bristol University, which led to her working both as a researcher and associate producer on programmes for the BBC, National Geographic and S4C.

In 2012, her interest in whale sharks took her to the Philippines. She joined a team at WWF-Philippines, and then became involved with Physalus, a non-governmental organisation specialising in Marine Vertebrates. Sally is now part of the small team that helps run Physalus’ Large Marine Vertebrates Project in the Philippines (LAMAVE). It is her work with Physalus that will form the basis of her lecture to the Cardiff Naturalists' Society. 

According to her website: "She continues to divide her time between her production work, developing her own film projects, working with rural communities to help them develop sustainably, conducting conservation research and holding her breath underwater for as long as possible to identify Whale Sharks and the occasional Manta Ray."

We look forward to welcoming you to the talk.

Wenvoe orchards: Sat 6 September 2014

Bruce McDonald led this fascinating walk in the Wenvoe area, attended by around ten CNS members, which took in four newly-planted orchards, a community nature reserve, two churchyards and an ancient burial chamber.

Orchards are a priority habitat and relatively easy to create, so the Wenvoe Wildlife Group is currently focusing on them to promote local biodiversity. The trees in commercial orchards are regularly replaced, often within a decade of planting, and are subject to numerous agrochemical sprays every year; so they have become a very poor habitat for wildlife. The Wenvoe group planted traditional tree varieties in four diverse locations last year that should provide a haven for wildlife for many years to come. These orchards are being primarily managed for wildlife biodiversity and not intensive fruit production; although they should eventually yield abundant fruit for community picking.


The first stop was the Community Orchard, on the edge of the playing field to the east of Wenvoe. A mixture of trees has been planted here, including traditional varieties of apples (e.g. Bardsley Grenadier, Ribston Pippin, and also crab apples), pears and plums (including greengage), along with medlar, quince, mulberry and hazel. The orchard has an impressive bee hotel, with a noticeboard on the back. Bruce mentioned that it would make a good research project for someone, investigating the species using it. Bumble bee nests are also being created, using buried flower pots, and Bruce is on the lookout for mouse droppings (so they can better mimic the abandoned mouse nests favoured by bumble bees). A pond has been dug, which in its second year is supporting a range of aquatic flora and fauna.


Taking the underpass, the next stop was St Mary’s churchyard in Wenvoe. Here we saw the old yew tree and a Balm-of-Gilead.


The tour continued along Pound Lane and through Wenvoe Woods to the farmland beyond, where the Elizabethan Orchard is located, in a fenced-off corner of a field. This was part-funded through the Glastir programme, whereby farmers get paid to increase biodiversity on farms. Using a National Trust listing of fruit trees in an Elizabethan orchard, the Wenvoe Wildlife Group planted medlar, quince, and apple and pear varieties that would have been familiar to the Elizabethans. Trees are widely spaced, up to 10m apart, based on old orchard records. The group is also constructing a Shakespearean garden here, with herbs that are mentioned in the Bard’s plays. A log pile and a pond are among the other habitats being created.


The walk continued along the golf course, through more woods and up to the St Lythans burial chamber - an ideal spot for a picnic lunch. This megalithic dolmen was built around 6,000 years ago, as part of a chambered long barrow (so it’s significantly older than Stonehenge). Current thinking suggests that corpses where put into a cave in nearby Goldsland Wood, and the skeletons moved to the St Lythans burial chamber (and the nearby and larger Tinkinswood burial chamber that is of a similar age).

The third orchard – the Welsh Orchard – is just around the corner from here on a triangular area surrounded by farmland. All the 28 trees planted in this area last year have Welsh connections, either having their origins in Wales or being varieties popular over long periods in Wales. They include the Nant Gwrtheryn Golden Russet variety, which has just been put on the market after its rediscovery on the Llŷn Peninsula. Two flower beds are being created here with medicinal herbs described by the Physicians of Myddfai, who were influential herbalists who lived in the twelfth century in the Carmarthenshire settlement of Myddfai. At least 40 plants they used were noted in the literature; and a selection is being planted here, including wormwood, tansy, angelica, marsh mallow, agrimony, henbane and others that you won’t find in the Cowbridge Physic Garden because of Health and Safety concerns! Beehives are also present in the Welsh Orchard and a new pond will be put in place this winter. The numerous insects (including grasshoppers and crickets of note), birds (e.g. willow warbler) and scuttling small mammals seen attest to the site’s value to wildlife.


A walk along the road took us to St Lythans village and its churchyard. From here it’s a short walk to the fourth and final orchard: the linear Wild Orchard. Here, trees have been planted along a field edge to enhance the existing trees and shrubs, which includes crab apples and other wild-type fruits. Among the trees planted last year were hazel, wild cherry, bird cherry and plum.


We continued towards Twyn-yr-Odyn. By the quarry monument we took a path, which had only been opened a few weeks previously, and soon found ourselves in the Upper Orchid Field. This 5-acre Community Nature Reserve is, like the new orchards, managed by Wenvoe Wildlife Group. The sloping meadow contains over 300 species of flowers, grasses, insects and birds. The seven orchid species recorded here are best viewed in June. There is one annual mowing to encourage meadow wildflowers. This is a habitat type fast disappearing in the UK. The field is surrounded by woodlands and hedgerows. Here you can explore and find Molluscopolis, a secluded area with information boards, where snails and slugs are positively encouraged.


The path at the bottom of the field continues down into Wenvoe.

INDOOR MEETINGS: AUTUMN 2014

The Cardiff Naturalists’ Society indoor meeting programme for 2014/2015 was recently announced. Click on the ‘Programme’ tab above to see the full programme.

Here, Indoors Meeting Secretary Hilary Wicks gives further information about the Autumn 2014 series of evening lectures. These all start at 7.30pm in Room 023 (ground floor) of the Cardiff School of Management (Metropolitan University, Llandaff Campus, Western Ave, Llandaff, Cardiff), unless otherwise stated. If lost, members can ask at the Main Building reception where a notice and signs to the lecture theatre will be placed.

The meetings start on Monday 22nd September with the AGM, followed with a talk by Linda and Rob Nottage on ‘Wildlife of the Dolomites’. Expect photos of snow-capped peaks, flower-filled meadows, and interesting insects, as they present highlights of their recent wildlife holiday in Italy.

The next lecture on Monday 13th October is by Sally Snow: ‘The world’s largest fish: an introduction to the whale sharks of the Philippines’. She will introduce us to the whale shark, the world’s largest fish, with fascinating insights into its biology, distribution and migration in the Philippines, with a look at the potential impacts of developing whale shark tourism initiatives both in the Philippines and worldwide. This lecture centres around the work of the NGO Physalus and its Large Marine Vertebrate Project, which has been studying whale sharks in the Philippines since 2011.

The following meeting on Wednesday October 22nd will be a talk by Paul E Bowden: ‘Birds and Mammals of Southern India (Bangalore to Kochi)’. He found Southern India a great place to visit in January, with favourable weather - a little rainfall and the temperature not too hot. Also at that time of year there was very little insect activity, so no malaria tablets were needed. He covered about 1,000 km (630 miles) in a three-week journey that took in Bangalore (Karnataka), Valparai (Tamil Nadu), and Thrissur and Kochi (Kerala), visiting five Nature Reserves. He recorded a total of 181 species of birds, including 14 endemics, and captured 113 species on HD video and 83 species as stills; while also photographing leopard, tiger, Asian Elephant, mongoose, spotted deer and numerous other mammals. Tea and rubber plantations were visited, and the journey included a drive across the Western Ghats. The whole trip was done by taxi, which he suggests is the best way to travel in India. By the end of the trip, the taxi driver was well trained in bird and mammal recognition!

In contrast, the next lecture by Adrian Lloyd Jones on Monday 6th November is entitled ‘Return of the Beaver’. This will be an illustrated presentation on Eurasian Beaver (Castor fiber) and how they create and manage wetland ecosystems for the benefit of many other species. The presentation will also cover the Welsh Beaver Project and its proposal for a reintroduction of the beaver to Wales.

The meeting on Thursday 13th November is a lecture by Kate Mortimer-Jones called ‘Seabed Life around Wales’. This is a combined meeting with Cardiff Group South and West Wales Wildlife Trust and Cardiff University student Wildlife Society, and will be held in the Wallace Lecture Theatre (Ground floor), Cardiff University, Park Place, Cardiff.

The last meeting in 2014 is the XMAS BASH on Monday 15 December, with Adam and Dave’s Biodiversity Quiz. They will test your (often obscure) knowledge of the plants and animals found in South Wales and the (crazy?) people who record them.

WENVOE ORCHARDS - Saturday 6th September

Our next field trip takes us around the 4 newly-planted orchards surrounding Wenvoe and ends with a walk through the Community Nature Reserve. This is a chance to see the pond, the Bee Hotel, St Lythans burial chamber and the new access to the Upper Orchid Field through Whitehall Quarry. A rural walk of 4 to 5 miles taking in whatever wildlife is around. Walking gear a good idea as recent rain has made some of the paths a bit muddy. If the weather is not good the walk will be shortened. Bring lunch. Dogs on leads are welcome but there are a few stiles.
 
Meet at 10am in the middle of Wenvoe village outside the Village Hall (large white building) at the junction of Old Port Road and Station Road West which is next to the school. For Satnav users the Village Hall does not have a postcode but CF5 6AG gets you close.

Rhos Pasture - Sun 3 Aug

The next Cardiff Naturalists Society field trip is to the rhos pastures near Brynna on Sun 3 Aug. It will be a day trip starting at 10.30am, so bring a packed lunch.

The trip will be led by Gill Barter of the Countryside Council for Wales. Among the distinctive flora and fauna to be seen on this distinctive purple moor-grass and rush pasture land are whorled caraway and bog bush cricket.

A late summer visit coincides with when the grazing cows are in the lower fields, allowing better access to the species-rich pastureland.
There is limited parking, so car sharing is recommended.
The entrance is at SS 970834. On a narrow lane going north from Pencoed, it is the last gate on the left before a hump back bridge over an old railway line. There is a footpath sign at the entrance.
Directions:
  
From B4280, on the northern edge of Pencoed, take the minor road signposted for Rhiwceiliog. Follow this lane, ignoring turnings, and take care on blind bends. After 1km you will see a field entrance on the left with a footpath sign, at grid ref SS 970834 and this is where we will meet. If you cross a hump back bridge over a disused railway line you will have gone too far so turn round - in the driveway entrance you will see on your right - and come back.
 
I assume people will have maps but if you think directions from the M4 are also needed, these are as follows.  From junction 35 of the M4 take the A473 northwards towards Llanharen. Go straight over two roundabouts (the second one is by the entrance to Pencoed college) and turn left at the third. You are then on the B4280 heading West, and the minor road signposted to Rhiwceiliog (mentioned above) is the first turning on the right.
