3rd July Green Drinks Ocean 2012

IWT's summer of sustainable seas continued on 3rd July at its monthly meeting of Green Drinks with Mike Walker from OCEAN2012 (http://www.ocean2012.eu/) coming to speak about overfishing and the OCEAN2012 campaign. OCEAN2012 is an alliance of organisations dedicated to stopping overfishing, ending destructive fishing practices and and delivering fair and equitable use of healthy fish stocks.

Mike outlined to the meeting some of the shocking facts and figures associated with overfishing. Currently, 63% of fish stocks in the Atlantic are overfished, 82% in the Mediterranean, and four out of the six stocks for which scientific advice is available in the Baltic. Over 20% of fish stocks are being fished beyond safe biological limits, meaning their very future is threatened. North Sea fish catches have declined from 3.5 million tonnes a year in 1995 to 1.5 million tonnes in 2007, and the larger fish at the top of the food chain are dying out as we literally eat our way through them. For example, North Sea cod reach spawning age at four years old, while the average age of cod caught in the North Sea is 1.6 years, meaning that 93% of cod are caught before they can reproduce. This means that there are virtually no large mature cod left. The difference between the cod caught in the past and the cod caught today can be seen in the two images below

At present, not only is the EU fleet is estimated to have the capacity to fish two to three times the sustainable level, but much of the fishing fleet is sustained by subsidies, meaning we are paying twice for our fish. The EU's Common Fisheries Policy needs to be changed urgently to bring about a sustainable fishing industry. Review of the Policy is underway at present, but vested interests opposing change mean it is vital to keep the pressure on policy makers.

23rd June Visit to SEALIFE Bray and fish shape

The Dublin Branch went on a tour of the National SEA LIFE Centre in Bray on Saturday June 23rd. This special guided tour of the aquarium with a dedicated SEA LIFE expert brought the group face to face with a Giant Pacific Octopus, sharks and many other creatures. This year’s new feature of the aquarium is a trail of rays featuring Ireland's only Cownose Rays. The tour took about an hour and afterwards IWT members and members of BirdWatch Ireland gathered on the beach for an Oceans 2012 campaign fish-shape photograph!  

16th June Visit to Ireland's Eye

Last Saturday 16th June the Irish Wildlife Trust went on a boat trip to Ireland's Eye off Howth in north Co. Dublin. Ireland's Eye is a designated SAC (Special Area of Conservation) and SPA (Special Protection Area). You can learn more about those designations by following the link to the National Parks and Wildllife Service website:

 There was a good turnout for the trip and the weather was cloudy but it stayed dry (mostly). Ireland's Eye is a spectacular island with its own Martello Tower and ruined church, and of course it contains a huge amount of wildlife, especially seabirds. Among the birds we saw were kittiwakes, nesting herring gulls and shags, (unfortunately some of these were dead). IWT's Conn Flynn who was leading the trip also showed the group some of the wild things on the seashore, including little insects that live in the seaweed called sandhoppers and some of the varieties of seaweed.

12th June EU Fisheries Meeting a "failure"

The coalition Ocean 2012 consider last Tuesday's agreement reached by the Minister of Fisheries of the European Union (EU) was a "failure". The agreement delays the end of fishing discards and defers the goal of maximum sustainable yield (MSY) of resources beyond 2015. Below is a link for a live blogging update and webcast of the meeting:

In the EC's own words: 'Europe’s fisheries policy is in urgent need of reform. Vessels are catching more fish than can be safely reproduced, thus exhausting individual fish stocks and threatening the marine ecosystem'. In many cases, fisheries rules, regulations and enforcement measures are not efficient; fishing capacity and efforts are not sufficiently limited or controlled and scientists’ recommendations for catch quotas that would allow fish stocks to recover are routinely ignored. There is a lack of transparency and traceability, and a lack of implementation/enforcement - the Common Fisheries Policy Reform aims to remedy this but the road ahead is long.

The OCEAN2012 coalition, including representatives from IWT, had formed this fish shape 4 days in advance of the meeting to highlight the need for change in fishing policy

9th June Killiney Beach Walk

Dublin Branch Ocean 2012 – Killiney Beach Walk – In Celebration of World Ocean’s Day 9^th June 2012

After 2 heavy rainy days in Dublin, the IWT Dublin Branch were spoilt by not only a mild dry and overcast day, but also by the leader, Tim Clabon, a marine and wetland expert and volunteer.

We explored the kelp beds and associated rock pools which were well exposed due to the very low tide, and learnt about the different seaweeds, including serrated wrack, sea lettuce, sugar kelp and oar kelp (see photo). A range of different crab species were temporarily caught and stored by Tim in a bucket (see photo).

Sadly litter was found including the plastic rings found on drinks cans and the remains of balloons (see photo). Both of these while looking harmless causes fatalities to wildlife either by ingestion as in the case of balloons and whales or plastic rings that can encircle diving birds.

Several South Dublin rivers enter the Irish Sea along Killiney Beach including the Deansgrange River and the Loughlinstown River. Tim came well prepared to demonstrate the abundant fresh water wildlife of the latter and took several samples of the water. In the net he pulled up a range of aquatic invertebrates, including eel and a very young flounder. 

On the return we explored the coastal vegetation and some brave souls even sampled the edible plants including sea radish and sea rocket (word of warning – only eat after an expert tells you its safe). After two stormy days it was not surprising to see a few fatalities including a female crab with her nest of eggs (see photo). Other wildlife seen today included, sand martins, cormorants a grey sea and some early attendees had even spotted some dolphins off shore.

Many thanks to Tim for a great celebration of World Ocean’s Day.

3rd June Habitats of Howth

Time and date: Sunday 3rd June, 11:00
Meeting point: Howth DART station
Details: Declan Doogue, one of the country’s leading botanists and author of Wild Flowers of Ireland: The Habitat Guide, led a walk through selected areas of Howth Head. Howth has a rich flora and a number of plant species that are not common in Ireland. The focus was on some of the habitat types that are quite rare as well as more familiar habitats like shingle ridges, coastal cliffs and the sea shore. Despite bad weather which meant there was a small turnout, those on the walk found it very informative.

12th May Himalayan Balsam Bash

Time - 10.00 - 13.00

Site – Bushy Park

Dublin IWT Himalayan Balsam Bashing

The Dublin Branch of the IWT joined forces with Dublin City Council, Ireland’s Inland Fisheries, Dodder Angling Club and various members of the public to attempt to deal with one of Ireland’s most unwanted invasive plant species. Himalayan Balsam (Impatiens glandulifera) is also known as Indian balsam, and Policeman’s Helmet due to the shape of the flower.

We also were honoured by a visit from the Lord Mayor, Andrew Montague and Minister of State, Fergus O’Dowd TD. The EU is currently developing a new EU Directive aimed at invasive species. Himalayan Balsam is one of Ireland’s invasive plants threatening our river ecosystems. The plant can grow up to 1.5 – 2m. It is an annual and so completely dies down in the Winter. It is a prolific seeder and the seed can last up to two years in the ground. However, unlike many other invasive species, Himalayan Balsam, can be very easily removed by young and old alike. Its shallow root system ensures that anyone can gently but firmly pull the stem and remove the plant. Large areas can be cleared and a second visit to the area in the second year will remove the plants that germinate from the soil’s seed bank.

Due to its rapid growth it can take over riverbanks forcing native species out. After it dies in the Autumn the riverbanks are left exposed and vulnerable during heavy rains. Native species would have good root systems that bind the soil on riverbanks.

It is important to either remove the pulled plants to prevent them from quickly going to seed or the pile of plants can be effectively covered blocking out any sunlight. Himalayan balsam has a high water content and rots very quickly. At the end of the day we all cleaned and disinfected our boots to prevent the spread of any seeds or diseases.  Dublin City Council treated all volunteers to freshly made sandwiches and bottles of water which were eagerly consumed!
