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.

Louth Nature Trust nominated for Ireland’s Greenest Places 2026

We are delighted to report that the LNT has been nominated for the long list of Ireland's Greenest Places 2026.

From the Dundalk Democrat: A conservation project for one of Ireland’s rarest breeding seabirds in County Louth has made the long-list of Ireland’s Greenest Places 2026 and as a result is now in contention to win a category award and potentially the overall title in Ireland’s Greenest Places 2026. The project, Baltray Little Tern Conservancy which is located at The Haven, at the mouth of the Boyne Estuary and has been in existence for established 20 years, has been nominated in the Greenest Community category. 

The Conservancy protect a nationally important breeding colony of the Little Tern (Sternula Albifrons), an amber-listed species of conservation concern.  In her pitch Helen Hanratty describes it as one of Ireland's most inspiring examples of community-led nature conservation, protecting one of our rarest and most vulnerable seabirds, while demonstrating how people and nature can successfully share a coastal landscape.

“For 20 years, the project has safeguarded this sensitive coastal habitat through a combination of scientific monitoring, habitat management, public engagement and round-the-clock protection during the breeding season.

The site forms part of a network of internationally important, protected areas (SPAs) and provides critical nesting habitat for Little Terns and other ground-nesting birds. The project tackles significant environmental challenges including habitat loss, climate change, coastal erosion, predation and disturbance from recreational users. Through seasonal fencing, predator management, volunteer support, education programmes and community outreach, the conservancy has successfully balanced public access with the protection of a highly sensitive wildlife site. From 41 fledged chicks in 2007, the colony produced a record 247 fledglings in 2025, achieving an 80% hatching success rate and demonstrating the effectiveness of long-term conservation action. This important east coast colony project contributes valuable scientific data through monitoring and bird ringing programmes that support conservation efforts nationally and internationally. Beyond the ecological benefits, the conservancy has inspired generations of volunteers, educated thousands of visitors about biodiversity and created a strong culture of environmental stewardship in County Louth.”

"Led by the Louth Nature Trust, it stands as a flagship example of how dedication, science, partnership and community action can reverse biodiversity decline and secure a future for wildlife. Baltray Little Tern Conservancy is not only one of Ireland's greenest places, it’s also one of its most successful conservation success stories.”

The Little Tern Conservancy was among almost 90 nominations received from members of the public from all over the country.One of the main aims of the competition is to showcase what can be achieved when people work together to deliver more sustainable and greener communities.

Eamon Ryan, former minister for the environment and leader of the Green Party, is one of the judges. He said the judging panel had been very impressed by the quality and diversity of the environmental projects being undertaken around the country. “It was a real challenge for us to come up with the long-list, and we spent many hours reviewing and debating the entries. But that is a compliment to the excellent quality of the work being done by the people, projects and places which were nominated. So, congratulations to the 23 projects and people who made it onto the long-list but also to everyone who entered and is doing such valuable work. Each place was judged on specific criteria including its beneficial environmental impact, level of ongoing collective engagement by the community and evidence of behavioural change by people. It’s clear that all the projects which entered are not just delivering significant environmental dividends but also really important community benefits also.”

Yes Minister!

We were graced by a visit from minister Chris O'Sullivan on Wednesday last. Chris is the Fianna Fáil TD for Cork South West, but is also a keen birdwatcher. In January 2025, he was appointed Minister of State at the Department of Housing, Local Government and Heritage with special responsibility for Nature, Heritage and Biodiversity. Born and bred in Clonakilty, West Cork, Christopher was a county councilor for 13 years, in which time he served as Mayor of County Cork. He was joined by various dignitaries form the council including Drogheda Mayor and Councilor, Michelle Hall. 

During the visit he toured the site and met several of the volunteers; fortunately the weather held up and the terns performed well. He also announced a number of funding packages for the promotion and protection of wildlife, including the LBAF which funds the little tern project.

Volunteers needed!

This week we are starting work on preparing the site at Baltray for the arrival of the ground-nesting little terns, expected in the next few weeks. The work will initially involve the erection of fencing around the site perimeter. Since there are a couple of kilometers of fencing, this is quite a task. Once this is up, around the end of the month, the job of wardening the site will begin. For volunteers this involves walking the perimeter, scaring away any crows or other predators, and informing members of the public about the project.

Please send an emails, text, WhatsApp message or whatever you prefer to bmartin@regintel.com or 0879145363.

Thanks!
