Only 1 native reptile, plus 1 recent arrival

Ireland has only one native reptile, the common lizard. While thought to be widespread in Ireland, to confirm this and pinpoint their most frequented habitats, the Irish Wildlife Trust is doing a National Lizard Survey. Anyone can take part - just don't confuse it with the smooth newt!

Slow worms were introduced to Ireland
Our second reptile, the slow worm (a legless lizard) is a recent arrival to Ireland. Many sources still claim that it is absent from Ireland, but it has been spotted in parts of the Burren in Co. Clare. It is a protected species in the UK.

Ireland's native reptile, the common lizard

Despite being partial to open, sunny, undisturbed and well drained habitats, Ireland's native common lizard thrives particularly well on Irish bogs. It also likes rough grassland, open woodland, woodland edges, sea cliffs, sand dunes, dry-stone walls, hedgerows, roadside verges, railway embankments, disused quarries or sandpits, suburban wasteland and golf courses. Not a fussy one is our lizard!

Our lovely lizard is a protected species
It was added to the species listed on Fifth Schedule of the Wildlife Act 1976 and Wildlife (Amendment) Act 2000 following the enactment of the Wildlife Act 1976 (Protection of Wild Animals) Regulations 1980. This means it receives full protection under Section 23 of the Wildlife Act 1976 and Section 31 of the Wildlife (Amendment) Act 2000. Together these prohibit the hunting, taking or killings of common lizards and wilful interference or destruction of their breeding places or resting places.

Conservation status of birds in Ireland

The conservation status of bird species found in Ireland can be considered at international, European and local levels. For instance:

  • A number of species found in Ireland are classified IUCN red list species in a global context.
  • Thirty three species of bird listed under Annex I of the EU Birds Directive 79/409 are deemed relevant to Ireland. Species listed in Annex I are subject to special conservation measures concerning their habitat in order to ensure their survival and reproduction in their area of distribution.
  • Eighteen species of bird found in Ireland are of conservation concern according to the Heritage Council.
  • Sixteen of these are priorities under the BirdWatch Ireland / RSPB NI Birds of Conservation Concern In Ireland (BoCCI) list which classifies birds as Red, Amber or Green, based on their conservation status and hence conservation priority. These sixteen belie a longer list: in total there are 18 Red list birds (of high conservation concern) and 77 Amber list birds (of medium conservation concern). All other regularly occurring species are classified as Green List and are not considered threatened.

4 distinctly Irish birds

Ireland has 4 species of bird which have adapted to their Irish habitats, are significantly different from their UK/European counterparts and are considered distinct Irish races. These are the
  • Coal Tit
  • Dipper
  • Jay
  • Red Grouse

What is the red list?

The 'red list' or 'red data list' is synonymous with the IUCN Red List of Threatened Species. Maintained and regularly updated by the World Conservation Union (IUCN) it is an international inventory of the global conservation status of over 40000 plant and animal species. The list evaluates and classifies the extinction risk of each species and subspecies. By doing so it impresses the urgency of conservation issues upon the international community and supports them in taking practical steps to reduce species extinction.

Benchmarking Ireland's birds


Ireland and Britain share many bird species (Ireland has even fostered some of Scotland's Golden Eagles) so it is fitting that we share a bird atlas. Bird atlases are the main source of information on the distribution and abundance of birds. Usually revised every 15 to 20 years, they are a benchmark that allow us to monitor bird populations over time. Fieldwork for an updated bird atlas for Ireland and Britain is due to begin in 2007.

The project will review winter and summer distributions of birds, thus providing valuable evidence of how birds are faring in their fast-changing urban and rural landscape. Meanwhile, you can:



  • use previously completed atlases to view and compare the distribution of breeding birds species in Ireland in 1968-72 and 1988-91 or to view the winter distribution of bird species in Ireland during the winters of 1981-82 and 1983-84

  • take a training session in spring 2007 so you can volunteer to help with atlas fieldwork. Contact Birdwatch Ireland on tel: 01-2819878 or email info@birdwatchireland.ie.



The new atlas is being developed by Birdwatch Ireland, the British Trust for Ornithology and the Scottish Ornithologists Club with support from Ireland's Heritage Council and the National Parks and Wildlife Service and Northern Ireland's Environment and Heritage Services.

Donegal's Biodiversity Project

The Donegal Biodiversity Project is gathering together records of all the wildlife found in Donegal. Almost 50,000 records of birds, plants, mammals and insects in the county have been computerised, with many more to be added.

Donegal moths
One group that it is focusing on in particular, is the larger (or macro) moths. Of 572 moth species in Ireland, the Donegal Biodiversity Project has recorded 378 in the county, but believes the true total is very close to 400. Each species is being photographed, its distribution is mapped, the habitat requirements of threatened species are being revealed, and important areas for moth conservation identified.

The largest badger population in Europe

Ireland may now have one of the largest badger populations of any European country. Estimates place between 210,000 - 250,000 badgers in the island of Ireland. Dr. Chris Small's 'The Badger and Habitat Survey of Ireland', published in 1995, 'estimated' the population at 200,000 in the Republic with a further 50,000 in Nothern Ireland.

34-ish mammals in Ireland

Some sources claim that 35 species of land mammal live on Ireland's land and around our coast (an example of a coastal land mammal is a seal). Others (me) say 34 species, still others (ahem... wikipedia) claim only 31. Well there's only one thing for it, a list. You'll find that below.

Some 50% of our current mammals didn't get here themselves, but were accidentally or deliberately introduced by people. I've grouped these together. Ireland's native mammals are those that were present during the last Ice Age and thrived afterwards. These are also grouped together.

Native Irish mammal species

  1. Bat - Common pipistrelle (our smallest and commonest bat)
  2. Bat - Soprano pipistrelle
  3. Bat - Nathusius' pipistrelle
  4. Bat - Brandt's bat
  5. Bat - Daubenton's
  6. Bat - Brown long-eared
  7. Bat - Leisler's
  8. Bat - Natterer's
  9. Bat - Lesser horseshoe
  10. Bat - Whiskered
  11. Red Deer

  13. Red Fox
  14. Pine Marten
  15. Otter
  16. Irish Stoat
  17. Badger
  18. Mouse - Field Mouse (also known as Wood Mouse)
  19. Mouse - House Mouse
  20. Pygmy Shrew (our smallest land mammal)
  21. Hedgehog
  22. Red Squirrel
  23. Grey Seal
  24. Common Seal

And the following were introduced:

  1. Bank Vole
  2. Grey squirrel
  3. Rabbit
  4. American Mink
  5. Feral Goat
  6. Japanese Sika Deer
  7. Fallow Deer
  8. Brown Rat
  9. Black Rat
  10. Brown Hare

While these went extinct:

  1. Wolf
  2. Giant Deer / Irish elk
  3. Brown Bear
  4. Muskrat
  5. Red Squirrel (was extinct, reintroduced, currently threatened)
  6. Reindeer
  7. Roe Deer
  8. Wild Boar
  9. Wild Cat
  10. Wild Pig (Greyhound Pig)

Over 20 Cetacean species (whales, dolphins, porpoises) frequent Irish waters

These include:

  1. Bottlenose dolphin
  2. Orca (killer whale)
  3. Northern minke whale
  4. Common dolphin
  5. Euphrosyne (striped) dolphin
  6. Risso's dolphin

Once upon a time in Ireland - wolves

By 1786, wolves were exterminated in Ireland. Secreted in Irish woodlands, they had survived for 40 years longer than in Britain. But wolf bounties, introduced by Oliver Cromwell, prompted the arrival in Ireland of profit-seeking hunters from Britain and Europe. Coupled with deforestation and habitat destruction this hunting precipitated their demise. Once plentiful, Irish wolves receive a mention in Shakespeare's 'As You Like It' and are depicted in the 800AD Book of Kells. Irish wolfhounds and deerhounds are descendents of wolf-dog crosses.

Wolves are now a protected species in most European countries, even where they are absent in the wild, as is the case in Ireland. This means that if someone can sneak them into the country and establish a population, it would be illegal for anyone to kill them. Interested?

More about wolves in Ireland in the 1600s and how they went extinct:

Once upon a time in Ireland - the Irish Elk

The Irish Elk (Megaloceros giganteus or Megaceros), now extinct, is the largest species of deer ever to have lived. Despite its name, it was not exclusively Irish, and during its reign it occupied open woodland and forest edges throughout Eurasia, from Ireland to China. The last one lived around 9500 years ago. Over 2 meters at the shoulders, it had the largest antlers of any deer, an impressive 3.5 meters from tip to tip - over twice the length of a bath! Their closest living relative is the Fallow Deer. In fact, Irish Elk are not closely related to either of the species we currently call elk.

Lots of Irish Elk fossils have been found in the peat bogs of Ireland. One can be seen in Ireland National Museum of Natural History.

Climate change threat to native Irish woodland

Phenology is the science of recording natural regularly occurring events, such as the annual timing of leaf budding and spring blossoms. Over many years, collection of this information of seasonal occurrences can help demonstrate how climate change may be affecting wildlife habitats, for instance by influencing trees to come into bud burst earlier.

Phenology provides some of the longest written biological records in Ireland. Based on such records, Ireland's Native Woodland Trust believes that climate change is a major threat to what little remains of Ireland's ancient woodland:

Steady increase in temperatures
"The 20th century has seen a steady increase in temperature with 1990s being the warmest on record. The mean temperature for January-March in the 1960s was 4.2°C compared to 5.6°C in the 1990s. The mean temperature in the spring 1999 was 6.1°C. Phenology offers real evidence that climate change is happening now and that it is already having a significant effect on our wildlife. Trees are coming into leaf sooner, and some typical spring flowers are increasingly being seen coming into bloom in November and December. Butterflies are appearing earlier, with evidence that some are begining to overwinter in Ireland. New birds, such as Egrets, and insects, such as some Dragonflies, are moving northwards into Ireland, with some other migratory species showing signs of staying year-round."

1% of Ireland is internationally important wetland

The Ramsar Convention on Wetlands, signed in Ramsar, Iran, in 1971, is an intergovernmental treaty concerned with the conservation and sustainable use of wetlands (especially those of importance as wildfowl habitats) and their resources. It supports conservation cooperation and action at local, national and international levels. The 153 participating countries are required to nominate Wetlands of International Importance based on significance in terms of ecology, botany, zoology, limnology or hydrology. The Ramsar Convention currently lists 1631 such wetland sites. Ireland accounts for almost 3% of these.

1% of Ireland’s own land area is designated as Ramsar site

  • Between 1984 and 1996, 45 wetlands in Ireland were designated, totalling 700 sq km
  • Ireland has four times the average number of individual Ramsar sites per participating country
  • However, each site being small, Ireland's total Ramsar site area is less than a 10th of the average per country
  • Worldwide, Ramsar sites total over 1500000 sq km. Irish sites accounts for approximately .05% of the total area.

Peppered throughout Ireland

A stopover for arctic-nesting species,

Unlike US warplanes, the cead mile birds that use Ireland as a migratory refueling point or winter stopover receive a cead mile failte. Ireland’s mild weather makes it a suitable home for many over-wintering water birds, although the crustaceans and shellfish must shudder in the soupy mudflats when they hear them arrive.

Winter hastens the arrival of arctic wading birds including knot, dunlin, godwit and redshank to probe our estuarine mud. Whooper swans, Canadian and Greenland geese, Icelandic, Russian and Scandinavian ducks make their annual return to our skies. Redwings, fieldfares, starlings, chaffinches, waxwings, also from Scandinavia, come visiting our autumnal gardens, picking at berries, bird tables and teasels. British lapwings and continental curlew and woodcock arrive. Summer visitors to Ireland include swallows, corncrakes, warblers and wheatears.

The habitats of these transitory birds need ongoing monitoring and protection. According to Birdwatch Ireland:

"Ireland's position along the major flyways of arctic-nesting species, together with its relatively mild climate (which provides ice-free feeding opportunities) supports large numbers and a high diversity of migratory and wintering waterbirds. Our diverse wetland habitats provide a home for an equally diverse wetland bird community, which are increasingly coming under threat from human developments. While a large proportion of Irish wetland habitats have already been lost through land claim during this century, the variety, scale and form of developments have never been greater than at present. Proposals for housing developments, marinas, aquaculture, tidal barrages and wind-turbines all threaten essential feeding and roosting areas for wintering waterfowl. The effects are compounded by the associated disturbance problems due to increased recreational usage of shorelines in the light of such developments. Ireland thus have an obligation to protect and conserve these species and the habitats they depend on, so that together with other countries along the various flyways, their populations are maintained."

These international responsibilities are recognised through the Irish government's participation in a number of conventions and agreements, including the

Dick Warner, of the waters and the wild

Dick Warner, environmentalist, contributes to the Irish Examiner and is widely recognised for his television documentaries, Spirit of Trees, Ironing the Land, and Waterways. The latter has an accompanying book, also called Waterways, which traces his watery journey by steam launch through the north-west of Ireland, down the rivers Shannon and Erne, drenched in the reedy landscapes and wildlife.

A decade of opposition to the Nitrates Directive

In 1991 Europe adopted the Nitrates Directive in order to protect waters from eutrophication related to agricultural sources of nitrate. In early 2004 the European Court of Justice judged that Ireland was non-compliant with the Nitrates Directive as the country had failed to establish an associated action programme. Later that year, Ireland sent its Nitrates Action Programme to the European Commission but it was rejected as inadequate.

By 2005 Ireland was the only EU 15 Member State not to have established an action programme and the country was at risk of incurring daily and lump sum fines.

Environmentalists and health experts supported implementation of the directive, citing that, for instance a 2004 Environmental Protection Agency survey revealed one third of all Irish rivers were polluted, and that 70% of Irish drinking water is taken from these rivers.

However, farmers opposed the directive, claiming it would disadvantage many involved in dairying. They argued that implementing the EU levels would make Irish farms uncompetitive and that Irish water quality was improving. The EU-wide limit of 170kg/ha of manure to protect ground water quality was said to be too low for Ireland, where soils and farming conditions were different to those in the rest of Europe. In counter arguement, others claimed that the directive would only financially affect the most intensive 2% of farmers.

The Government ultimately revised its Action Programme to improve the environmental standards while protecting farmers' interests. Ireland applied for a derogation allowing farmers to use higher amounts of manure (up to 250kg/ha) than provided for in the directive on certain grasslands. The EU accepted the derogation in November 2006. The directive had already been signed into law in Ireland in January in 2006.

The Nitrates Directive - protecting waters from agricultural nitrate pollution

The EU Commission adopted the Nitrates Directive in 1991. Its aim is to reduce water pollution caused or induced by nitrates from agricultural sources and prevent further such pollution. Its primary emphasis is on the management of livestock manures and other fertilisers. The Nitrates Directive requires Member States to:
  • monitor waters and identify waters which are polluted or are liable to pollution by nitrates from agriculture
  • establish a code of good agricultural practice to protect waters from such pollution
  • promote the application by farmers of the code of good agricultural practice
  • identify the area or areas to which an action programme should be applied to protect waters from pollution by nitrates from agricultural sources
  • develop and implement action programmes to reduce and prevent such pollution in the identified area: action programmes are to be implemented and updated on a four-year cycle
  • monitor the effectiveness of the action programmes, and
  • report to the EU Commission on progress.

There's only one Eanna Ni Lamhna

She recently sang "I know an old lady who swallowed a fly" in the middle of a shopping centre with as much gusto (but not as much success) as her regular radio broadcasts. Her up-for-anything approach and bubbling enthusiasm breathes life into wildlife and nature. According to Amazon this broadcaster, writer, botanist, entomologist, field naturalist, President of An Taisce, Honorary Member of the Irish Peatland Conservation Council and former diver is also "noted for her matter-of-fact knowledge, humour and folklore-laden take on Irish wildlife". Particularly interested in creepy-crawlies and bats and with a solid knowledge of all things wild. As she travels the country she takes people on nature walks, saves seals, performs general wildlife detective duties and deals with all sorts of enquiries from the general public. Altogether great fun and definitely someone you'd enjoy taking for a pint in the local. Just don't ask her to sing.

Look out for her with co-conspirator Derek Mooney on RTE Radio’s ‘Mooney’ show (also available on podcast via iTunes) or get a copy of one of her books:

Glenveagh National Park, Co. Donegal

This 170 sq km granite-bedded wilderness of lakes, ice-carved cliffs, gentle hills, deep peat bogs and the swampy Owencarrow river valley cradles Ireland's golden eagle reintroduction project. Natural woodlands of oak and birch are inhabited by badgers, foxes and stoats. Bird life includes siskins, treecreepers, redstarts and wood warblers. Pyramidal Errigal, Donegal highest peak overlooks the park, its uplands punctuated by ravens, peregrines, stonechat and grouse, and prettied with the yellow flowers of tormentil and bog asphodel. Glenveagh (meaning Glen of the Birches) contains a herd of red deer (not of native Irish stock).

Ireland's writers, broadcasters, photographers, naturalists

As if peering into a pond, look closely at Ireland's media and Ireland's extensive network of contributers to environmental awareness and conservation becomes clearer. Some of these people are listed below. My plan is to develop this list and write an entry for each individual over time:

  • Michael Viney, natural historian, writer. He may regale us with blustery tales of his life in the west or in a mere three words set us straight on our wildlife observations. Another Life and Eye on Nature are his Irish Times columns. Read a well written review of one of his books.
  • Dick Warner
  • Eanna Ní Lamhna
  • Derek Mooney, television presenter, broadcaster, most importantly of the excellent Mooney Goes Wild
  • And his merry men Richard Collins, Eric Dempsey, Terry Flanagan - read their profiles here
  • Sylvia Thompson, reviews, news, ideas - in her Horizons column in the Irish TimesMike Brown, photographer, author
  • Simon Berrow, Project officer with Shannon Dolphin and Wildlife association
  • Pádraig Whooley, sightings coordinator of the Irish Whale and Dolphin Group
  • Gordon D'Arcy, naturalist and artist
  • Leitrim organic centre (full of great people, and excellent vegetarian chefs!)
  • Vincent Hyland

Book: Images of Irish Nature

By photographer Mike Brown, self-published, November 2006. Available in Easons.
According to an Irish Times review, this book is "full of images of dimensions of nature that happen so quickly we rarely get a chance to observe them properly". Many of the photos were taken in Counties Cork and Kerry between 2004 and 2006. His subjects include foxes, the wood white butterfly, basking shark, whitethroat, convolvulus hawkmoth, cuckoo pint plant, otter and hen harrier.
This follows Mike Brown's first book 'Ireland's Wildlife' published in 2004, and his subsequent involvement in RTÉ's Wild Trial series which, with varying degrees of success, challenged Irish personalities to master the art of wildlife photography.

Pearl mussels vs the Irish forestry industry

Ireland's state forestry department Coillte is being restricted in its forestry activities in an attempt to prevent the extinction of pearl mussels, a protected species under European law. Ireland is one of the last places in Europe where this bivalve survives and has the largest remaining population. The pearl mussel is Ireland’s longest living species, living for up to 120 years. Recent surveys show that in all rivers where previously healthy populations of the species survived it is now facing extinction.

Born before Irish Independence
In recent years, many young mussels have succumbed to deteriorating water quality caused by river pollution and siltation. For instance, in 2004 phosphorous and nitrate silt leaked into the Owenriff river in Galway. This caused an algae bloom that asphyxiated most of the mussels living downstream. Such events are often related to the amount of artificial fertiliser applied to Sitka spruce trees, a species introduced to Ireland in the 1830s and now grown commercially. Sitkas need aerial fertilisation if they are to grow on infertile Irish bogland. When the trees are harvested, subsequent soil erosion leads to silt and fertiliser entering rivers. The mussels that manage to survive pollution events are generally the larger ones, many over 100 years old. Their age means that, even though a population remains, its ability to reproduce is inhibited.

Pearl mussels need unpolluted rivers
In 1990 the pearl mussel occurred in just 10 to 12 rivers remote Irish rivers. At the time, these flowed through rural areas where forestry and fertilisers were minimal. Since then, rapid economic and population growth intensified development and forestry activities throughout the country. As a consequence, water quality has deteriorated.

A mussel.. reforming the Irish forestry industry
The minister for agriculture, Mary Coughlan, imposed a moratorium on forestry activities in all pearl mussel areas in May 2005, 18 months after the problem was identified by officials in the National Parks and Wildlife Service (NPWS). Coillte can now neither continue fertilising the trees in these areas nor, it is claimed, cut them down in an economically viable way. The Irish forestry industry faces millions in lost revenue, and it is unclear what the future holds for the Irish pearl mussels.

Book: Complete Irish Wildlife

By Paul Sterry, Published by Collins, 2004. Small enough to slip in a Hermes handbag, comprehensive enough to iD the slugs eating your vegetables, simple enough to quickly satisfy your bird spotting tendencies. The wipeclean covers are a blessing if you spill your sunscreen, but the size of the photos makes plant identification difficult. Descriptions are short and leave you wanting more, which may be a good thing. The introduction is by Derek Mooney (more on him later). If you only want one guide this is a good place to start.

Highest mountain in Ireland

Ireland's highest point is Carrantuohill in County Kerry. At 1038m high you'd need to stack eight and a half Carrantuohills to reach the height of Everest.

Ireland's coastline

Ireland's coastline measures 1448km. At an average pace of 5.6 km/hr you could walk around Ireland in 259 hours, or 11 days if you didn't stop.

National Parks in Ireland

There are six national parks in Ireland, covering a combined area of 596 sq km, or only 0.86% of Ireland's total land area (68890 sq km). The criteria and standards for national parks are laid down by the World Conservation Union (also known as IUCN - International Union for the Conservation of Nature). Much of the land is also designated as a SAC (Special Area of Conservation (PDF format)) under the EU Habitats Directive.


Travelling clockwise around Ireland from Dublin the national parks:

  1. Wicklow Mountains National Park, Co. Wicklow (159 sq km)
  2. Killarney National Park, Co. Kerry (103 sq km)
  3. The Burren National Park, Co. Clare (17 sq km)
  4. Connemara National Park, Co. Galway (30 sq km)
  5. Ballycroy National Park, Co. Mayo (118 sq km)
  6. Glenveagh National Park, Co. Donegal (170 sq km)

There be golden eagles in them hills

In the cradle of the Glenveagh National Park in Co Donegal, at the edge of northwest Ireland, the Golden Eagle Reintroduction Project has been reintroducing these raptors to Ireland since 2001. Donegal was chosen for its suitable habitat, the locals’ love of wildlife and the rapport between the farming community and conservationists. Tourism groups also have an interest as the Eagles may attract tourists. The majority of their potential ranges here are Natura 2000 sites, protected habitats for flora and fauna of European importance. Research indicates that County Donegal could hold 7-10 pairs of Golden Eagles and Ireland may eventually have 50 – 100 pairs.

Ireland currently has 6 breeding birds of prey species, the lowest number in the European Union. Habitat loss, egg collection and persecution (shooting, hunting, poisoning) caused the extinction of White-tailed Eagle, Osprey, Red Kite, Marsh Harrier and Goshawk since the 1700s. Golden Eagles became extinct in Ireland in 1910.

These raptors have a 2m wing span, can live for over 20 years and hunt rabbits, hares and other prey over a broad (up to 260 square km) territory. The Irish Farmers Association was consulted on and supported the introduction despite some farmers fearing that the Eagles would predate lambs. Compensation was promised should any such predation be proven.
The project is funded by by the National Parks and Wildlife Service and the Heritage Council. Dúchas (Ireland’s authority for nature conservation) is also involved.

The reintroduction project meets 53 reintroduction guidelines laid down by the World Conservation Union (IUCN). Four to five week old Eaglets are sourced from the Scottish wilds under licence. Sourcing Eaglets has recently become more difficult as recent years have been poor for Golden Eagle breeding in Scotland.

Individual released birds are tracked with radio transmitters and can be identified by a tag on each wing. 46 birds have been released, and at least 26 were known to be alive during 2005. Others may be dead or carry failed radio transmitters. Five territories are now occupied. Out of four pairs two produced clutches of eggs, but none successfully hatched – in some cases because the birds are still young and inexperienced breeders. Enough eagles will be released to ensure a sufficient number survive to form a viable breeding population. This project aims to release enough have a dozen breeding pairs at Glenveagh by 2011.

The island of ireland

Once upon a time, and for 15000 years, ice a mile high blanketed Ireland. When the lingering Ice Age finally released and the Irish ice departed it left a landscape scoured. Across land bridges linking Ireland, Britain and mainland Europe plants and animals arrived to colonise the new lowlands, mountains and valleys. The world’s ice continued to melt, the sea levels to rise, and some 8000 years ago Ireland became the island we now know, accounting for just 0.01% of the world's total land area and the most westerly point of Europe.

Though at Alaskan latitudes, the country's climate is tempered, due partly to the neighbouring waters of the Gulf Stream and partly the prevailing southwesterlies that veering and backing make landfall on our sodden coast. These offerings from the Atlantic mean it is never too hot, never too cold. But without doubt it is wet. Rain lingers year round, never far away, though is most frequent in winter, the western counties and, inevitably, on the day of your parade.
