The Caves of Cefn Meiriadog, Denbighshire , a Bishop Darwin, a Chimney Sweep, Landmines and Science

Dr Elizabeth Walker enteretined us with the fascinating history of the Pontnewydd Cave and it's surrounding area, on the side of the Elwy Valley.

The history goes back to when the first human beings lived here. They were hunter gatherers who found warmth and shelter in the cave. There are a number of small remains (teeth)

By the 1530s, the caves of the Elwy valley were already famous, being noted by the antiquary John Leland in his itinerary of 1536–39, but their potential archaeological significance was not examined until 1830, when Cefn Old Cave was visited by the Reverend Edward Stanley (later Bishop of Norwich)

In more recent times Darwin visited the area along with Adam Sedgwick. Darwin considered this trip to North Wales to be one of his most important formative tours before he headed off for his most famous adventures.

More recently it was also used as an arms storage centre during the war.

Programme Change

Please note that the Roath Park walk on Sunday the 13th of May bas been changed from a 10:00 start to an 11:00 start.

It's sure to be a wonderful day with Tony Titchen see the programme for more details

Birds, Ecosystems and Climate Change

We had a fascinating talk by Dr Rob Thomas whi is a Lecturer in Biosciences at Cardiff University

He explained the many ways in which bird studies on the macro and more local level can be really useful as indicators of climate change and the development of mmodels from the decades of records taht have been collected by the birders amongst us

Dr Thomas asked that we let people know of the ways that they can get involved in these research studies, or just support the researchers by opting for an eco friendly holiday in one of the research areas.

We're happy to do so for a supporter of the society, and you can find more details here

CNS Transactions now on-line

Many years ago the National Library of Wales asked us if they could scan and put on-line the Cardiff Naturalist's Society Transactions

We heard nothing despite chasing, but finally they see to have got around to it and they have been spotted by one of our members

So here they are... Reports and transactions (Cardiff Naturalists' Society), 1900-1981

It's a fantastic resource and secures a copy of our works into the digital age

There is a comment in the text that "Reports and transactions (Cardiff Naturalists' Society) was published annually, containing scholarly articles on geology, archaeology and natural history, with book reviews and society notes. It was published between 1870 and 1986. For digitisation, the publication has been split into two sequences: Vol. 1 (1867) – Vol. 31 (1898-1899) and Vol. 32 (1899-1900) -Vol. 100 (1986)."

I can't find part 1, if anyone spots it please let us know

Pond Conservation

We recently received this which is something that we'd like to pass on and publicise

A Happy New Year from all at Pond Conservation

Have you seen frog or toad spawn in your garden pond? Then join in with our Big Spawn Count, so that we can find out more about the breeding success of our frogs and toads in garden ponds nationally.

The Big Pond Dip and Thaw surveys have given us a lot of new information about garden ponds. Now we are working with our colleagues at Amphibian and Reptile Conservation (ARC) and Amphibian and Reptile Groups of UK (ARGUK) to find out more about the numbers of frogs breeding in garden ponds.

We are also keen to find out more about our common toad. Although, toads are less associated with garden ponds – there is some indication that the use of gardens is becoming more frequent due to loss of traditional breeding habitat. This is something we would like to find out more about.

You can take part in our Big Spawn Count by going to your pond and counting the number of spawn clumps present. For more information about this, and to enter your results online go to our Big Spawn Count pages.

We'll certainly try and give it a go at our house
