12th March - Trip to St. Enda's

On Saturday 12th March, the Dublin Branch went to visit St Enda's: Carmel, our guide, was excellent. She took us through all the important rooms in the Pearse Museum, engaging with everybody and keeping information at just the right level. After a brief visit to the so-called Nature Room we went round St Enda's Park where Carmel showed us the various follies. Certainly the most interesting of these were the 'Summerhouse', the 'Hermit's Cave' and 'Emmet's Fort', which she unlocked for us so that we could have a good look around this astonishing little building. A very interesting day out.

21st February Birdwatching Broadmeadow Estuary

On Sunday 21st February the Dublin Branch went birdwatching in Broadmeadow Estuary. Despite terrible weather, our guide Sean Fox showed us quite a few species of birds, including brent geese, teal, black-tailed godwit, stonechats, little egrets, cormorants, and of course the mute swans for which the estuary is famous. Highlight of the trip however, was the sight of a sparrowhawk hovering over the motorway in search of prey. Alas the weather was too wet for the kingfisher which Sean assured us was a regular visitor.

As the morning wore on the wind and rain eased off, and we were able to look through our binoculars and telescopes without getting fogged up. The sun fitfully came out and we had time to look at the swans at close quarters as they gathered around us looking for some bread to eat. There was no need to panic, however, as Sean informed us that the old story about swans being strong enough to break a  man's leg was nothing but a myth!

2nd February - Green Drinks The Pine Marten

This month the IWT Dublin Branch heard Ruth Hanniffy, Ireland Projects Support Officer in the Vincent Trust give a talk on these fascinating and little known animals, that are making a bit of a comeback in Ireland, and may just be helping to control the grey squirrel!

Once common throughout the country, by the 20th century the pine marten had become extinct from the majority of Ireland, surviving only in a few isolated and fragmented populations mainly in the west. The main reasons for the species’ decline were related to hunting for its fur; loss of habitat through the destruction of forests; direct and indirect poisoning and persecution as a potential predator of livestock/game populations. As all of these factors declined, so has the pine marten recovered so that it has extended its range across most of Ireland. However, the most recent estimate is that there are only about 2,700 individuals on the island, so it is still Ireland's rarest mammal and will remain vulnerable for the foreseeable future.

The spread of the pine marten has coincided with the decline of the grey squirrel, which is now missing from large parts of its former range in the midlands, roughly the same areas where the pine marten is now expanding. It is thought that the pine marten may have a hand in this, by predating on the greys more than the reds, as the greys are heavier, and live more on the ground, making it harder for them to escape. At the moment however, this is only speculation, and further investigation is needed. Ruth will shortly be beginning studies on behalf of The Vincent Trust trying to get further evidence of what exactly is going on, by studying the interaction of both red and grey squirrels with this elusive creature.

January 23rd - Trip to National Botanic Gardens

On Saturday January 23rd the Dublin Branch took a trip to the National Botanic Gardens in Glasnevin. Our guide Niamh was a mine of information about the many interesting things to be seen in the gardens, even in January. For example, there was already a beautiful display of snowdrops, rises and other bulbs, and Niamh showed us the shrub wintersweet, which flowers in January with a delicious, delicate fragrance. Mistletoe could also be seen growing on some of the trees, one of the few places in Ireland it can be seen. Niamh informed us however, that it is a bit of a pest and needs to be cut back regularly to avoid damaging its host tree. A tree looking beautiful at this time of year was the myrtle with its striking cinnamon coloured bark, looking a bit like a eucalyptus.

After a while Niamh took us into the warmth of the glasshouses, which was very welcome on a cold January day. There we learnt that all cacti are succulents, but not all succulents are cacti. According to Niamh, cacti are only seen in the Americas, which means you will never see them appearing in a spaghetti western! We also learnt many other interesting facts, such as teabags are made out banana leaves, and that vanilla comes from the seedpod of an orchid. Even in winter there were many orchids in flower in the orchid house, giving a gorgeous display. Finally Niamh showed us the carnivorous plants, like the pitcher plant, and our own native butterwort, which trap insects with their sticky juices, and slowly digest them. Alas there were no venus flytraps on display, as apparently people can't resist poking them to make them snap shut, and the plants become exhausted and die. Overall, the group were very happy at all that they saw, and agreed that a trip to the Botanic Gardens is highly recommended!

Green Drinks 5th January - 'Our Grass has always been this Green'

This month Dublin's Green Drinks heard IWT's Padraic Fogarty talking about how agriculture has shaped our landscape for centuries, but in its modern form just how environmentally friendly is it? Despite the official image of Ireland promoted by the government in its Origin Green labelling programme, with its slogan that 'our grass has always been this green', a lot of modern agriculture is having a destructive impact on our environment. Farmland biodiversity has been declining for the last three decades, which makes a mockery of the idea that Irish food is sustainably produced.

While Origin Green does monitor carbon emissions, it does nothing to stop the pollution of our watercourses from farm run-off, the decline in farmland birds, the needless culling of badgers, or the degradation of our uplands. For example, pollution of our rivers from silage and slurry run-off threatens the survival of species, such as the rare fresh water mussel, and the continuing destruction of our hedgerows is depriving many wildlife species of desperately needed habitat.

Pádraic also talked about what's in store for nature as government plans for ever-increasing production are rolled out, and about the ways we can accommodate the needs of farming and nature conservation. However, it is obvious that at the moment, environmental concerns are not given anything like the weight they should by politicians and civil servants, and conservation agencies remain badly underfunded. Unless things change we are facing a serious biodiversity crisis on this island.

November 15th - Birdwatching Bull Island

On Sunday November 15th IWT Dublin Branch went birdwatching on Bull Island, led by Sean our ever knowledgable guide. Despite the blustery weather and works to the sea wall at the causeway (don't mention the war!), the branch got to see quite a few birds. There were the pale bellied Brent geese, mallard, shelducks, shovellers, teal and wigeon, along with little egrets, curlews, herons and of course some hooded crows. An interesting fact that Sean shared is that there will always be lots of birds where streams come out into the sea, because believe it or not, the birds like to wash the salt off their feathers. So, at the point where the Naniken river comes out into the lagoon, there were indeed lots of birds gathered. Altogether an enlightening afternoon.  Photos courtesy of Brendan and Stephen.

Green Drinks 3rd November - Community Energy

The November Green Drinks, on Tuesday, November the 3rd, saw Kate Ruddock of Friends of the Earth Ireland talking on Community energy - how small local community groups can together use energy and resources most efficiently, and in a way that does least ecological damage. This has been slow to take off in Ireland compared to other countries, for various reasons, including a difficulty in selling excess energy onto the national grid. However, with enough determination, communities can achieve successful projects that provide them with self sufficiency in clean renewable energy.  

One of the most hopeful projects is happening on the Aran Islands, where the islanders are aiming to make the islands completely self sufficient in energy using wind power by 2022. Another place where this has been done is in Templederry, Co. Tipperary where the Templederry Community Group have constructed a windfarm.

The government is also going to introduce a White Paper for a scheme to allow local communities to form co-ops and invest in windfarms. It is hoped that this will chart a way forward for local communities and also help to lay to rest some of the controversies that have sprung up around windfarms in recent times. Progress towards renewables is happening, even if the pace of change is often frustratingly slow.
