Lullymore West is a cutaway bog from which peat was commercially extracted in the 20th century. The bog has regenerated to become an important refuge for wildlife. Over 300 species of bird, plant, insect and animal are found here. The variety of habitats on the bog including grassland, scrub woodland, pools and ditches support the biodiversity of life on the site.

Location of Lullymore West Bog

Lullymore West Bog is one of three properties owned and managed by the Irish Peatland Conservation Council in Kildare. The map below shows the location of Lullymore West Bog in relation to the Bog of Allen Nature Centre and Lodge Bog (north).

Lullymore West Bog Location map

Lullymore West Bog is part of the great Bog of Allen. The site is located on the north western edge of the mineral soil island of Lullymore, approximately 7km from Allenwood. Land use around Lullymore West Bog includes a coniferous forest plantation to the west and agricultural land to the north and east. The south side of the bog is privately owned raised bog. Lullymore West Bog was donated by Bord na Móna to the Irish Peatland Conservation Council (IPCC) for conservation in 2005.

Kildare, IrelandThe image to the left is a surface view of Lullymore West in summer showing the purple flowers of Devil’s Bit Scabious, the food source for the caterpillars of rare European Marsh Fritillary Butterfly. Adult butterflies take nectar from the flowers.

Lullymore West Bog is 4.5ha in extent and is being conserved by the Irish Peatland Conservation Council for its diversity of butterflies and moths. With 21 out of the 31 butterflies occurring in Ireland found here and over 150 species of moth, the site is exceptional in Ireland. The endangered Marsh Fritillary Butterfly (Euphydryas aurinia), an insect protected under the EU Habitats Directive is just one of the species being conserved here.

Habitats for Wildlife

Lullymore West Bog, Co. Kildare Habitat Map 2007Habitat Map of Lullymore West Bog, Co. Kildare overlain on the air photograph for the site. Different symbols show the locations of the habitats described on the bog. The reserve boundary is in red. Land use around the reserve can be seen including coniferous forestry to the west, grassland to the north and east and privately owned cutover bog to the south. The access point to the bog is shown by the black arrow. Map drawn by Pádraic Fogarty in 2007.

Six habitats have been recorded and described on Lullymore West Bog. The distribution of the habitats on the bog can be seen in the habitat map which was prepared by Pádraic Fogarty working with IPCC staff. The habitats found on Lullymore West Bog are:

  • scrub woodland
  • grassland
  • cutaway bog
  • bare peat
  • wet depressions and drains
  • recently felled woodland

The grassland habitat is the most species rich and visually is most stunning in late summer when knapweed, devil’s bit scabious and measdow sweet are flowering among the moor grass giving a very distinct pink and purple hue to the site.

On crisp cold bright sunny days in spring, the treelines on the perimeter of the site are stunning when the yellow catkins of willow are seen against a beautiful blue sky.

In spring, after the rains, the wet depressions are filled with water. These become alive in March with tadpoles of frogs. In the damp areas, the mosses are very visible at this time especially the orange brown moss Calliergonella cuspidata.

The total number of animal species on Lullymore West excluding moths and butterflies is 66. Early in spring green tiger beetles are commonly seen in the cutaway bog habitat. Most obvious in the summer months are the craneflies, hover flies and spit bugs. In early autumn spiders make funnel shaped nests in the grassland and you may catch a glimpse of a female with her egg ball near the nest.

The site is rich in moths with 156 species recorded in 2006 by the Moth Society of Ireland from light traps placed on the site overnight.

In 2004 Dr Martin Speight discovered a species of Hoverfly at Lullymore West, which was new to Ireland. The species is Eupeodes goeldlini. Dr Speight collected a male hoverfly whilst it was feeding on dandelion flowers during the month of May.

The birch and willow woodland habitats are a refuge for bullfinch, chiffchaff, cuckoo, willow warbler, white throat, thrush, robin and gold finch. Thrush anvil sites are commonly seen on the bog where there is rocky mineral soil exposed. Banded snail shells are seen in such areas in abundance.


21 different species of butterfly are found on Lullymore West Bog, out of a total Irish species list of 31. In 2007, IPCC began a programme of butterfly monitoring on the reserve. A 1km butterfly transect has been established throughout the site. Regular walking of the transect is undertaken between April and October.

The grassland habitat at Lullymore West bog is a breeding area for the Marsh Fritillary butterfly because of the abundance of its food plant Devil’s Bit Scabious in the vegetation. IPCC monitor the population of this butterfly in Spring and Autumn each year. The larvae overwinter in webs deep and they emerge on sunny days in spring. For example in the Spring season of 2007 we counted 21 nests of the marsh fritillary butterfly larvae. These had survived the winter period of 2006/2007. In autumn 11 nests of the larvae were recorded which were due to over winter on the bog in 2007/2008. Poor weather during the flight period of June and July, scrub woodland encroachment onto the grassland habitat of the butterfly larvae and the development of purple moor grass into large clumps are all factors that determine population breeding success each year.

Devil's Bit Scabious (Succisa pratensis) - food plant of the Marsh Fritillary Butterfly (Euphydryas aurinia)Succisa pratensis or Devil’s Bit Scabious ­ the food plant of the marsh fritillary butterfly was found to be most abundant in the open habitats of the site including grassland, recently-felled woodland and bare peat. In these habitats cover of the plant reached up to 100% of the vegetation.

Conservation Management of Lullymore West Bog

IPCC’s Conservation Management Plan for Lullymore West Bog focuses on the actions that need to be undertaken each year to protect and enhance the butterfly and moth diversity of this site and to raise awareness of the wildlife importance of the bog. Records of wildlife are being kept by the IPCC on an on-going basis, the spread of scrub woodland is being controlled, drains have been blocked and the whole site has been fenced off as a safety precaution. Scientific monitoring of the Marsh Fritillary Butterfly is on-going annually. The increase in abundance of Devil’s Bit Scabious, the food plant of the Marsh Fritillary Butterfly larvae is a management priority. A butterfly transect on the site is being monitored each year in liaison with the National Biodiversity Data Centre.

IPCC developed a Conservation Management Plan for Lullymore West Bog to guide activities at the site for the next five years. The overall aim of the Conservation Plan for Lullymore West Bog is to conserve the biodiversity of butterflies and moths on the site. The plan contains eight conservation objectives as follows:

  1. To maintain the marsh fritillary butterfly population on Lullymore West Bog and to expand the area of suitable habitat for the butterfly.
  2. To ensure that the boundaries of Lullymore West Bog are visible to the public.
  3. To prevent harmful human affects to Lullymore West Bog.
  4. To increase the Health and Safety awareness of visitors and researchers.
  5. To monitor Lullymore West Bog so as to ensure the effectiveness of the Conservation Plan.
  6. To encourage further research on Lullymore West Bog and to maintain an archive of research findings.
  7. To retain the traditional use of Lullymore West Bog as a training site for surveyors of the Marsh Fritillary Butterfly.
  8. To seek local and national recognition of the conservation importance of Lullymore West Bog.


Volunteers play a vital role in the on-going reserach and management work being undertaken at this site. Please contact IPCC if you would like to participate in the annual programme of work which includes weekly butterfly transect monitoring between April and October, marsh fritillary nest monitoring in Spring and Autumn, tree removal and spread control in summer, regular site clean ups and drain blocking. Wetland habitat creation is also planned on the site. You can contact us from this link
