Irish Vegetation Classification (IVC) Community Synopsis Irish Vegetation Classification (IVC) www.biodiversityireland.ie/ivc Community Synopsis Scientific name Cynosurus cristatus – Trifolium pratense grassland Common name Crested Dog’s-tail – Red Clover grassland Community code GL3D Vegetation The main grass species of this rather low sward are Cynosurus cristatus and Agrostis capillaris, with Holcus lanatus, Anthoxanthum odoratum and Festuca rubra also constant (mean graminoid height = 13.2, n = 198). The broadleaved herbs comprise chiefly Plantago lanceolata, Trifolium repens, Prunella vulgaris, Trifolium pratense, Cerastium fontanum and Hypochaeris radicata (mean forb height = 8.7 cm, n = 198). Rhytidiadelphus squarrosus is a constant beneath and can be abundant. There are often signs of some agricultural improvement, with Senecio jacobaea, Bellis perennis, Lolium perenne and Cirsium arvense being fairly frequent. Ecology The Cynosurus cristatus – Trifolium pratense grassland may be regarded as a fairly standard neutral, semi-natural pasture community of mineral soils (mean organic content = 18.4%, n = 130) in the lowlands (mean altitude = 88 m, n = 198). It occurs on sloping (mean slope = 9.7°, n = 198), well-drained soils of medium fertility. Sub-communities No sub-communities are described. Similar communities This community is similar in composition to the GL3C Festuca rubra – Trifolium pratense grassland and the GL3E Festuca rubra – Rhinanthus minor grassland. Its lower sward is typically more species-rich than either, however. It lacks the tussocky grasses found in GL3C and some of the more calcareous indicators found there (e.g. Galium verum, Briza media). In GL3C Agrostis stolonifera rather than Agrostis capillaris is a constant. GL3D differs from GL3E by lacking Rhinanthus minor and also by being somewhat more semi-improved.

    British & Irish Botany 1(2): 107-116, 2019 Long-term monitoring of Green-winged Orchid (Anacamptis morio) at Upwood Meadows NNR, Huntingdonshire Peter A. Stroh* Botanical Society of Britain and Ireland, Cambridge University Botanic Garden, 1 Brookside, Cambridge CB2 1JE, UK *Corresponding author: Peter Stroh: [email protected] This pdf constitutes the Version of Record published on 21st May 2019 Abstract The results of monitoring a population of Anacamptis morio over a 40-year period (1978-2017) in a permanent plot at Upwood Meadows NNR, Huntingdonshire, are presented. Flowering and vegetative plants were recorded each year, with individuals relocated using phenomarkers and triangulation. The majority of plants flowered for over half of their lifespan, the average lifespan of an individual plant was almost 10 years, and the known maximum lifespan above-ground for an individual was at least 36 years. The average age of the cohort became much younger over the course of the study, with potential reasons given including extreme old age, a lack of recruitment, and climate. Key words: demography; fixed plot; recruitment; mortality; triangulation Introduction In 1962 Terry Wells became the Nature Conservancy’s first grassland ecologist, based at Monks Wood, Huntingdonshire. In his first three years at the Research Station he set up a number of long-term monitoring projects, mainly across the chalk and limestone of southern England, designed to study the dynamics of British orchids and changes to associated vegetation. One of the first of these studies, set up in the early 1960s, followed the fate of a cohort of Autumn Lady’s Tresses (Spiranthes spiralis) at Knocking Hoe in Bedfordshire.

Therefore, the aim of our research was to describe elements of seed propagation of some minor grass species. On the basis of field experiments, different spacing and seed quantities were investi- gated for Beckmannia eruciformis, Cynosurus cristatus and Elytrigia elongata aiming at an optimal seed production. Satisfying seed yields were obtained even at a reduced (50% to 75%) amount of seed quantity, as compared to theoretical (or normal) values, calculated on the basis of number of plants per area unit. Key words: Beckmannia, Cynosurus, Elytrigia elongata, seed yields, INTRODUCTION European semi-natural grasslands are a result of long, stable utilization of lowland and mountain areas for hay and as a pasture. Their botanical com- position was extremely rich since the absence of fertilization enabled the presence of many low-growing species (Scotton et.al. 2012). Recent changes in agriculture, with the use of mineral fertilizers, mechanization, drainage and the introduction of highly selected varieties of forage species, led to a significant changes of grassland ecosystems with for example re- duction of species and varieties used.

We also appreciate the mapping expertise brought to the project by Fernando Fernandez Valverde. Finally, we thank the farmers of Offaly and Roscommon for giving us permission to survey their land and for the background information they provided. Executive Summary Ninety-one sites and 305 relevés in Roscommon and Offaly were surveyed from May to September 2007. Of the 91 sites 39 were within a designated area, SAC (Special Area of Conservation) or NHA (Natural Heritage Area). Wet grassland was the most frequent semi-natural grassland habitat, recorded at 65% of sites, and dry-humid grassland was the least frequent found at 8% of sites. The most common EU Annex I grassland habitats were Festuca-Brometalia (6210/6211) recorded at 18% of sites and Molinia meadows (6410) recorded at 13% of sites.
