The typical vegetation along the canal towpath comprises Field Maple, Hazel, Alder, Rowan, Guelder-rose, willows and some very large poplars, and in one spot a large Crataegus pedicillatus Cockspur Thorn, the first of many interesting plants we were to encounter during the day. The “Perry Pond” containing Ranunculus trichophyllus Thread-leaved Water-crowfoot Moving on from where the canal ends we headed along the main path, keeping Grove Pool to our left and Middle Pool to the right, and leaving this path onto a smaller path, we made our way to the “Perry Ponds”, a group of small ponds named in honour of the late naturalist Alan Perry, one of the two local men (the other being Brian Jones) who had the vision of saving the Fens as a nature reserve, and started the Pensnett Wildlife Group, without which the reserve may never have been created. The ponds were originally excavated to provide a cluster of breeding ponds for amphibians, and in particular, for the large population of Great Crested Newts that Fens Pools is renowned for. The typical vegetation in and around the pond Ranunculus trichophyllus Thread-leaved Water-crowfoot margins included Eleocharis palustris Common Spike-rush, Myosotis laxa Tufted Forget-me-not, Juncus tenuis Slender Rush, Elodea nuttallii Nuttall’s Waterweed, Ceratophyllum Once satisfied that we had recorded everything from the emersum Rigid Hornwort and in each of the small ponds we Perry Ponds we continued along the main path towards the encountered a submerged aquatic not found in the others. cindery mounds where Cerastium arvense Field Mouse-ear, a The first pond contained a colony of Zanichellia palustris low-growing, early-flowering perennial has been known from for many years.

For many years this meadow has traditionally been a favourite spot for locals to graze their ponies and with very few animals here now the long-term effect this will have on the flora in this area remains to be seen. Ophioglossum vulgatum Adder’s- tongue fern has long been known from this meadow and at one time was relatively easy to find. In recent years heavy grazing from tethered ponies has all but eradicated it from the open parts of the meadow so a challenge was put out to Osmunda regalis Royal Fern the group to see who would be the first to find an Adder’s- tongue. After several minutes of searching the honour went Time constraints prevented us from exploring the large area to Paul Reade who discovered several plants tucked well in of open grassland that opened out before us, so reluctantly amongst bracken, one of the few places that the ponies tend we started to make our way back, pausing briefly to admire to avoid.

THOMAS KING was born on the I4th April 1834, at Yardfoot, Lochwinnoch, Renfrewshire, a farm which was owned and occupied by his father. He received his early education in a small school in the village of Glenhead. He was destined to be a teacher, and in 1855, after the sale of his birthplace, and the removal of the family to Glasgow, he entered the Normal Training College of the Free Church of Scotland. The early bent of his mind revealed itself in his attendance on the class of Botany in that Institution. In 1862 he was appointed teacher of English in the Garnet Bank Academy, where, in addition to the ordinary subjects, he taught an advanced class of Botany. The work of the session, however, proved too much for his strength, which had never been robust, and he was obliged to relinquish the position.

  • Irish Vegetation Classification (IVC) Community Synopsis
    Irish Vegetation Classification (IVC) www.biodiversityireland.ie/ivc Community Synopsis Scientific name Trichophorum cespitosum/germanicum – Eriophorum angustifolium bog/heath Common name Deergrass – Common Cottongrass bog/heath Community code BG2F Vegetation Trichophorum cespitosum/germanicum is the main component of this community, forming large wefts of mottled brown stems later in the year. Calluna vulgaris and Erica tetralix form the patchy dwarf shrub layer. Other constants are Eriophorum angustifolium , Molinia caerulea , Potentilla erecta and Narthecium ossifragum . In the bryophyte layer, cushions of Racomitrium lanuginosum are the most regular feature but it tends not to dominate and is frequently joined by Sphagnum tenellum , Sphagnum capillifolium , Hypnum jutlandicum and Pleurozia purpurea . Further investigation amongst these plants will often yield some diminutive strands of Odontoschisma sphagni and Diplophyllum albicans . Several other species of sphagna are occasional. Cladonia uncialis is frequent but provides sparse cover. Ecology This is a community of upland peatlands (mean altitude 370 m, n = 112) occurring on wet, acidic and infertile peats. Mainly these are the deep, ombrogenous peats of upland blanket bog, but this vegetation also occurs on shallower soils as wet heath. Sub-communities No sub-communities have been described for this community. Similar communities In no other community does Trichophorum attain such dominance.

  • Site Synopsis
    SITE SYNOPSIS SITE NAME: CLOONLOUM MORE BOG NHA SITE CODE: 002307 Cloonloum More Bog NHA is situated approximately 5 km south-west of Tulla, mainly in the townlands of Cloonloum More and Clooncool in Co. Clare. The site comprises a raised bog that includes both areas of high bog and cutover bog. The north-western margin of the site is bounded by a road, while the other margins are bounded by areas of cutover and grassland. The raised bog consists of one crescent-shaped lobe. There is an absence of permanent pools and hummocks/hollows on the high bog and there are large areas of cutover. This raised bog is of particular interest as it is one of the few remaining raised bogs in the county. A small lake, Lough Gara, is included at the south of the site. Much of the high bog vegetation is typical of raised bogs in Ireland, consisting of Ling Heather (Calluna vulgaris), Cross-leaved Heath (Erica tetralix), White Beak- sedge (Rhynchospora alba) and Deergrass (Scirpus cespitosus). Bog-rosemary (Andromeda polifolia) is found on this bog, although not in abundance. The bog moss (Sphagnum spp.) cover is quite variable, with species such as S. capillifolium, S. magellanicum and S. fuscum. The cutover areas surrounding the bog have become dominated by Purple Moor-grass (Molinia caerulea) and Gorse (Ulex europaeus). The lake at the south of the bog is surrounded by the Common Reed (Phragmites australis) and the Bulrush (Typha latifolia). Current landuse on the site consists of peat-cutting around the edge of the high bog, and the drainage associated with this.

R Meade To cut, or not to cut. A very straightforward question, but so much Foreword more succinct than the answer. This is the dilemma often faced by managers of land for nature conservation where the easiest solution is to just follow what others are doing. As a former habitat specialist for a statutory nature conservation body, I am familiar with the pressures to provide clear guidance and one I remember well is the popular belief that any trees on lowland raised bogs should be cut down and prevented from regrowth. While there is a case for adopting this principle in many situations there are those in which it is not necessary, and is even undesirable from other perspectives such as the trees’ contribution to the landscape. It means that the conservation land manager must not only be aware of the bare bones of the received wisdom, but also of the caveats that make it possible for him or her to arrive at a reasoned judgement for their specific situation.

Confirmed Date: Dec 2005: Site surveyed and assessed for designation; designation boundary identified. Summary - Reasons for Selection/Interest of Site: Very extensive mosaic of ‘ffridd’ habitats and former mine spoil supporting complex of semi- upland and lowland habitats, partly contained within conifer plantation. Main components are ancient semi-natural woodland fragments, other semi-natural woodlands (mainly upland oak, Quercus sp) together with wet woodlands of alder (Alnus glutinosa), wet heathland, dry heathland, marshy grassland and semi-improved neutral grasslands. Also there are some bracken slopes, scrub, small ponds, streams and sections of dismantled railway. There are areas of semi- improved acid grasslands to the south especially. The habitats intergrade to form a complex mosaic, and may therefore also include some small areas of improved or low diversity semi- improved grassland, but any such areas are a very minor component. Great crested newt occurs in small pools within the SINC, and noctule and pipistrelle bats have both been recorded. Water vole may occur and a small badger sett is present.

    SITE SYNOPSIS Site Name: Galtee Mountains SAC Site Code: 000646 Situated in east Limerick and south Tipperary, the Galtee Mountains are Ireland's highest range of inland mountains. Galtymore has an elevation of 920 m and the main ridge, mostly above 700 m, extends approximately 10 km from east to west. The mountains are derived from folding of Old Red Sandstone and Silurian rocks. Heath is the main vegetation type within the site, with significant amounts of humid grassland and blanket bog occurring also. There is a series of small corrie lakes on the northern side of the mountain range, and the site encompasses the headstreams of numerous tributaries of the river Suir. The cliffs above the corries support arctic- alpine vegetation and the site as a whole supports several notable Irish rarities. The site is a Special Area of Conservation (SAC) selected for the following habitats and/or species listed on Annex I / II of the E.U. Habitats Directive (* = priority; numbers in brackets are Natura 2000 codes): [4010] Wet Heath [4030] Dry Heath [4060] Alpine and Subalpine Heaths [6230] Species-rich Nardus Grassland* [7130] Blanket Bogs (Active)* [8110] Siliceous Scree [8210] Calcareous Rocky Slopes [8220] Siliceous Rocky Slopes In areas of dry heath Heather (Calluna vulgaris) dominates the vegetation, with Bilberry (Vaccinium myrtillus) also common. This habitat type often grades into wet heath and alpine/subalpine heath. It is probably best developed on the steeper slopes. Additional species recorded from the areas of alpine/subalpine heath include Dwarf Willow (Salix herbacea), Heath Bedstraw (Galium saxatile), Hare’s-tail Cottongrass (Eriophorum vaginatum), Great Wood-rush (Luzula sylvatica) and Starry Saxifrage (Saxifraga stellaris), amongst others.

  • GRAPHIE by Cornelia D. Niles with INTRODUCTION and BOTANICAL
    A BIBLIOGRAPHIC STUDY OF BEAUVOIS' AGROSTO- • GRAPHIE By Cornelia D. Niles WITH INTRODUCTION AND BOTANICAL NOTES By Aones Chase nrntODTJCTiON The Essai d?une Nouvelle Agrostographie ; ou Nouveaux Genres des Graminees; avec figures representant les Oaracteres de tous les Genres, by A. M. F. J. Palisot de Beauvois, published in 1812, is, from the standpoint of the nomenclature of grasses, a very important work, its importance being due principally to its innumerable errors, less so because of its scientific value. In this small volume 69 new genera are proposed and some 640 new species, new binomials, and new names are published. Of the 69 genera proposed 31 are to-day recognized as valid, and of the 640 names about 61 are commonly accepted. There is probably not a grass flora of any considerable region anywhere in the world that does not contain some of Beauvois' names. Many of the new names are made in such haphazard fashion that they are incorrectly listed in the Index Kewensis. There are, besides, a number of misspelled names that have found their way into botanical literature. The inaccuracies are so numerous and the cita- tions so incomplete that only a trained bibliographer* could solve the many puzzles presented. Cornelia D. Niles in connection with her work on the bibliography of grasses, maintained in the form of a card catalogue in the Grass Herbarium, worked out the basis in literature of each of these new names. The botanical problems involved, the interpretation of descriptions and figures, were worked out by Agnes Chase, who is also respon- sible for the translation and summaries from the Advertisement, Introduction, and Principles.
