Conservation of Killarney fern - Trichomanes speciosum
28th January 2008

Spores of the Killarney fern have been successfully germinated by Noeleen Smyth, Sinead Phelan & Gerry Douglas of Kinsealy Teagasc Research Station.

To date the lack of a suitable sterilisation technique for the sensitive spores has been a drawback, however, a low nutrient and somewhat acidic medium has given a 42% germination rate.

A catalogue of alien plants in Ireland - now on-line
13th April 2007

Over the last 200 years or so, nearly as many alien plants have been recorded in Ireland as there are native taxa. This catalogue, published in 2002, is the first annotated check-list of the approximately 920 alien plant taxa recorded in Ireland.
Catalogue entries include comments on frequency of plants, whether they are established or not, habitats where found, possible means of introduction, historical records and vice-county distribution. The catalogue also includes an historical overview and description of the current alien flora - some 645 taxa recorded between 1987 and 2001.
Copies of the catalogue are available from the National Botanic Gardens visitor centre.

Club sedge - Carex buxbaumii
19th May 2006

This plant has only ever been found on one tiny islet in Lough Neagh - Harbour island. It was discovered in July 1835 by David Moore, who later became Curator of the Gardens. By 1890 the plant had become extinct due to scrub clearance and cattle grazing on the island.
However the dedicated interest of a number of botanists ensured its survival in gardens in Dublin, Down and Louth, and we still have original material growing at the Gardens.

Irish Fleabane - Inula salicina
19th May 2006

A community-based conservation project to consolidate and establish new populations of the highly endangered Irish Fleabane has been initiated by the village of Terryglass (Co. Tipperary), the National Botanic Gardens and BEC Consultants.
Once widespread around the shores of Lough Derg, this species began to decline due to the changes in lake level which the area has undergone since the construction of the Shannon hydroelectric scheme in 1927, and the the marked fluctuations in lake level during the period 1939-45, when demands for water from the lake was at its greatest.

Sea Stock - Matthiola sinuata
15th May 2006

A new educational display of the Sea Stock is being established at the National Botanic Gardens as part of its native plant conservation and education programme on the threatened flora of Ireland. Extinct in Ireland since the 1930s, sea stock is a native of south-wetern coasts of Europe, and was probably at the limit of its geographic range.
However, disturbance of coastal dune systems, where it formerly grew, is a major factor in its disappearance.

Global Partnership for Plant Conservation
27th October 2005

The National Botanic Gardens hosted the 1st international conference of the Global Partnership for Plant Conservation from the 22 to 25th October 2005.

The Wollemi Pine - Wollemia nobilis
2nd September 2005

The Wollemi Pine is one of the world's oldest and rarest tree species belonging to a 200 million-year-old plant family - Araucariaceae - the monkey-puzzle family.
It was known from fossil records and presumed extinct until it was discovered in 1994 by a bushwalker in the Wollemi National Park just outside Australia's largest city, Sydney. Dubbed the botanical find of the century, fewer than 100 Wollemi Pines exist in thew wild, and these show no genetic variability. A major project to propagate the species was undertaken in order to develop financial support for its continued survival.

Encephalartos woodii
26th July 2005

This cycad, one of our most treasured plants, was put back on show in the east wing of the Curvilinear house in July 2005. As a South African plant it is an appropriate place for it to be grown.
Encephalartos woodii has only ever been found once in the wild, what is more the only plants are male, which means this species, with no surviving females, is unable to reproduce, so technically it is already extinct.
Our plant was obtained in somewhat peculiar circumstances, and the register records it as "Encephalartos way of E. Alten[steinii]" costing 1 guinea from Sander & Sons.

British and Irish Botanic Gardens adopt Plan to save endangered species of plant
8th April 2005
