Welcome to Louth Nature Trust

Biodiversity is a widely used word these days. On the face of it, it means diverse life, or maybe just lots of different species together in one place. But it is really a reflection of the genetic diversity of species and their interaction with one another and with the environment. The highest biodiversity is achieved in places where species have been living together for a long time. This is because over time species evolve together. This massively increases the biological productivity of systems because these close interactions that develop over millennia are extremely efficient. It also drives speciation processes as species become more and more specialised, increasing species richness and abundance in these systems, and is the reason why native species are so important

Globally the most diverse systems are in tropical rain forests, or coral reefs.

In county Louth the most biodiverse systems are to be found in Louth’s several estuaries: the Boyne, the Dee and Glyde, the Fane and the Castletown and Flurry. Also notable for biodiversity is Carlingford Lough, and in particular its tidal rapids and shore in places. Ardee bog, despite its past exploitation for turf, still supports significant biodiversity. Over the years I have searched of ancient Oakland habitats in Louth but so far only a few patches in Ravensdale and perhaps north of Omeath, and maybe at Dunaney Point.

The whole of the Louth shore represents good biodiversity areas, some better than others.

Away from the coast, the other main source of biodiversity are in its wetlands, most of which have been surveyed. Notable are the rivers, the three small loughs, Drumcah, Toprass and Cortial Loughs. Several wetland areas in the Cooley mountains are high biodiversity, especially around Corakitt, the White bog and a few other patches. Though not huge biodiversity, the Cooley mountains and Clogherhead represent relatively unspoilt habitats supporting specialist species. Similarly several dune systems represent great examples of succession ecology, especially between the Baltray and Clogherhead. There are also several other small bogs, fens, marshes and ponds scattered around the county which are of good local interest, and a few of national or international importance.

But biodiversity is under constant threat, mostly from human impacts, from development, farming, industrial activity, transport and all the rest. Global warming has increased the pressure, contributing further to the habitat loss which is the main driver of biodiversity loss.

The Louth Nature Trust supports a halt to biodiversity loss through the restoration a protection of natural habitats.

The Louth Nature Trust operations are largely funded by Local Biodiversity Action Plan fund, operated by the National Parks and Wildlife Service of the Department of Housing, Local Government and Heritage, through the Heritage Office of Louth County Council.

Mell Quarry update

According to local ecologist Tony Conaghy, the tufted ducks successfully produced several ducklings on the ponds this year, which the kestrel pair produced four to five chicks. in the meantime debate continues over the future of Mell Quarry: https://www.independent.ie/regionals/louth/drogheda-news/pictures-show-potential-for-louth-towns-very-own-central-park/a2012775358.html

Green Island

A small population of sandwich terns has set up to breed on Green Island in Carlingford Lough, arriving late (end of June) probably from a failed colony elsewhere. Over recent years attempted nesting on green island has consistently failed in recent years, mainly doe to the presence of large numbers of herring and great black-backed gulls, as well as over washing during spring tides. This may be exacerbated by the passage of the Seatrucks usually travelling at 20 knots up the lough. There are also several pairs of herring gull nesting in close proximity.

Botany Update

Botanical team Ciaran and Enda Flynn have recorded an exceptional year for lesser butterfly orchids (Platanthera bifolia) with 39 specimens recorded at a regular site in the Cooley mountains this year. Ciaran discovered a new record for the county two years ago in the form of Killarney fern (Trichomanes speciosum) in the Cooley Mountains, written up in the latest edition of Irish Botanical News. Other finds over recent years include bog orchid (Hammarbya paludosa) one of our rarest wild flowers, and many others. Ciaran is a county recorder for the BSBI in County Louth.

National Heritage Week launched at Beaulieu House

National Heritage week 2024 was launched at Beaulieu house on the 18th July at Beaulieu House in a very well attended event featuring many aspects of Irish heritage. The event started with a steam train from Dublin to Drogheda. The Louth Nature Trust put up a stand that was very well attended and drew particular interest from Minister Malcolm Noonan. After the opening speech adn the exhibition a wonderful lunch was provided.

RTE visitation to Little Tern site

On Friday morning 19th July we had a visitation from Laura Hogan from RTE to cover the news for the Baltray little tern site. She was shown around the site and fencing by Dominic and Bronagh, who outlined the huge volunteer effort that goes into the project. Fortunately this has been a very successful year, and may break previous records. The sotry is cered here on the RTE web site and will feature on the Six pm News on Saturday the 20th July.

Bird Flu Back?

We are getting worrying reports of bird flu at Rockabill island, possibly signaling the continuation of the bird flu epidemic that started in 2020. it is not clear which strain the particular version is but there is evidence from around the world that it may be H5N1: https://www.smithsonianmag.com/science-nature/four-important-questions-about-bird-flu-answered-180984378/
