The Orkney Local Biodiversity Action Plan 2002 The Orkney Local Biodiversity Action Plan A plan for action to conserve Orkney’s Biodiversity Prepared by Orkney’s Biodiversity Steering Group for The Orkney Environment Partnership December 2002 Orkney’s Community Biodiversity Project is supported / funded by the following organisations: Orkney FoundedField in 1959 Club Aim: To encourage the study and conservation of the natural and cultural heritage of the County Environment & Rural Affairs Department © 2003 Printed by The Orcadian Limited, Hatston, Kirkwall, Orkney, KW15 1DW Tel: 01856 879000 www.orcadian.co.uk FOR FURTHER INFORMATION ON ANYTHING CONTAINED WITHIN THIS MANUAL, PLEASE CONTACT: NADINE RUSSELL COMMUNITY BIODIVERSITY PROJECT 8 BROAD STREET KIRKWALL ORKNEY KW15 1NX TEL: 01856 888760 EMAIL: [email protected] Glossary Biodiversity: The term biodiversity describes the variety of life at all biological scales, from diversity within ecosystems, communities, species and populations, to the level of genetic variation present within species and their constituent populations. In short it encompasses the diversity of all life on earth. CITES: Convention on International Trade of Endangered Species Community: A naturally occurring assemblage of plant and animal species living within a defined area or habitat. Communities are named after one of their dominant species (e.g. pine forest) or the major physical characteristics of the area (e.g. a freshwater pond community). Conservation: The sensible use of the earth’s resources in order to avoid excessive degradation and impoverishment of the environment. This includes the maintenance and preservation of natural environments and the creation of new ones (e.g. nature reserves, national parks, and SSSIs). CPS: Countryside Premium Scheme (agri-environment scheme concluded in 2000) Dystrophic: A body of water that contains a large amount of undecomposed organic matter derived from terrestrial plants. Poor in dissolved nutrients and therefore unproductive. EC: European Community Ecosystem: A biological community and the physical environment associated with it. Endemic: Describes any species that is restricted to one or a few localities in its geographical distribution. Endemic species are often confined to islands and are vulnerable to extinction. EU: European Union Eutrophic: A body of water where increased mineral and organic nutrients has reduced the dissolved oxygen, producing an environment that favours plant life over animal. FA: Forestry Authority FC: Forestry Commission FWAG: Farming and Wildlife Advisory Group Habitat: The place in which an organism lives, which is characterised by its physical features or the dominant plant types.

Conserving the Biodiversity of Orkney Biodiversity is simply "the Variety of Life, and refers to the whole range of animals, plants and microorganisms on earth, from the tiniest bug to the mightiest whale, along with the ecosystems in which they live. Conserving biodiversity is not just about rare and threatened species and habitats, but the commonplace as well. All those who care about the countryside are in fact appreciating biodiversity. It is important for maintaining the quality of our lives and is intimately bound up with it. Although the countryside may still appear visually attractive, it has become apparent that much of its richness and diversity is under threat; some plants and animals that were once familiar are now rare, others have become extinct altogether. This century the UK has lost over 100 species including 7% of our dragonflies, 5% of our butterflies and more than 2% of our fish and mammals (according to the UK Biodiversity Action Plan). More are in danger of disappearing, especially at the local level. Nature has an in-built propensity to change, continually evolving new variants and new species, but all of this occurs naturally over a length of time. The world is losing species at a faster rate now than ever before, as a result of human activity; biodiversity cannot evolve fast enough to compensate for losses at anything like the current rate and so is declining at an accelerating rate. Orkney is a place of great beauty and biodiversity, but here too the marine and terrestrial environments are under pressure from increased economic activity. In the last half-century some species have greatly declined or even disappeared and the area of semi-natural vegetation has greatly decreased. There are many reasons why we should conserve biodiversity: • In the context of sustainability we should be handing on to future generations a world that is richer than the one we inherited; • Species which evolved over thousands of years may be lost very quickly, and cannot be re-created; • Natural processes help to protect our planet, e.g. through regulating climate and air quality; • In maintaining the productivity of our crops we rely upon a reservoir of their wild relatives and the pool of genetic material that they hold; • In conserving the biodiversity of Orkney not only will we be taking responsibility for the quality of our local environment, we will be contributing to global biodiversity. This plan marks a major step in the conservation of Biodiversity in Orkney. It has been authored by the Biodiversity Steering Group of the Orkney Local Biodiversity Forum, which is now part of the Orkney Environment Partnership, and is proposed for adoption by the constituent members of the Forum. A 1 2. The Orkney Local Biodiversity Action Plan and its National Context The UK Biodiversity Action Plan (UKBAP) was launched in 1994 as a means of meeting the UK's obligations under the Biodiversity Convention (signed by the UK and over a hundred other countries at the Rio Earth Summit in 1992) to "develop national strategies, plans or programmes for the conservation and sustainable use of biological diversity”. The stated goal of the UK BAP is to "conserve and enhance biological diversity within the UK, and to contribute to the conservation of global diversity through all appropriate mechanisms". A UK Steering Group has been established to take this forward. The Scottish Biodiversity Group (SBG) was established to progress the UKBAP in Scotland. The SBG has now evolved into the Scottish Biodiversity Forum (SBF). This Group is chaired by the Scottish Executive and includes representatives from statutory conservation agencies, non-governmental organisations, landowners and land managers, fisheries interests, commerce and industry, academics and recreational interests. “Biodiversity, the UK Steering Group Report” (1995) sets out the Government’s goals for Biodiversity into the 21st Century and details those habitats and species for which Action Plans should be produced. The report identifies 39 Priority habitats. The report also identifies 1,250 species, which are globally threatened, or declining in the UK, and sorts them into two groupings “Species of Conservation Concern”; and within this “Priority Species”. The intention was that action plans would be produced for the entire “Priority Species” list, but not for the other species on the published “Species of Conservation Concern” list. Six volumes of National Action Plans have been produced to date. National Action Plans have been prepared for all Priority Species and Habitats. The Local Process To achieve the UK's commitments, action has to be taken at both national and local levels. Local Biodiversity Action Plans (LBAPS) are seen as the means by which the UKBAP will be delivered at the local level. Targets set nationally for species and habitats of conservation concern will be translated into actions, which are achievable in a local context. In addition, LBAPs are expected to provide a focus for the conservation of locally valued species and habitats. The Orkney Local Biodiversity Action Plan (Orkney LBAP) is Orkney’s contribution to the process of conservation of biodiversity, which is taking place throughout the country. This plan identifies actions which we can take locally, and which will make a contribution to the conservation of those species and habitats identified as being “at risk” or “threatened” in the UK as a whole. It is presented as a series of individual species, habitat and area action plans and associated guiding principles. All these plans will identify the most important sites, both designated and non-designated. A key element of the LBAP

Biogeographic relict, extinction risk, global warming, species richness, sub-alpine prairies Abstract. During the last few decades the tree line has shifted upward on Mediterranean mountains. This has resulted in a decrease in the area of the sub-alpine prairie habitat and an increase in the threat to strictly orophilous moths that occur there. This also occurred on the Pollino Massif due to the increase in temperature and decrease in rainfall in Southern Italy. We found that a number of moths present in the alpine prairie at 2000 m appear to be absent from similar habitats at 1500–1700 m. Some of these species are thought to be at the lower latitude margin of their range. Among them, Pareulype berberata and Entephria flavicinctata are esti- mated to be the most threatened because their populations are isolated and seem to be small in size. The tops of these mountains are inhabited by specialized moth communities, which are strikingly different from those at lower altitudes on the same massif further south. The majority of the species recorded in the sub-alpine prairies studied occur most frequently and abundantly in the core area of the Pollino Massif.

  • Cruising the ISLANDS of ORKNEY
    Cruising THE ISLANDS OF ORKNEY his brief guide has been produced to help the cruising visitor create an enjoyable visit to TTour islands, it is by no means exhaustive and only mentions the main and generally obvious anchorages that can be found on charts. Some of the welcoming pubs, hotels and other attractions close to the harbour or mooring are suggested for your entertainment, however much more awaits to be explored afloat and many other delights can be discovered ashore. Each individual island that makes up the archipelago offers a different experience ashore and you should consult “Visit Orkney” and other local guides for information. Orkney waters, if treated with respect, should offer no worries for the experienced sailor and will present no greater problem than cruising elsewhere in the UK. Tides, although strong in some parts, are predictable and can be used to great advantage; passage making is a delight with the current in your favour but can present a challenge when against. The old cruising guides for Orkney waters preached doom for the seafarer who entered where “Dragons and Sea Serpents lie”. This hails from the days of little or no engine power aboard the average sailing vessel and the frequent lack of wind amongst tidal islands; admittedly a worrying combination when you’ve nothing but a scrap of canvas for power and a small anchor for brakes! Consult the charts, tidal guides and sailing directions and don’t be afraid to ask! You will find red “Visitor Mooring” buoys in various locations, these are removed annually over the winter and are well maintained and can cope with boats up to 20 tons (or more in settled weather).

Jørgensen: Dept. of Natural History, University Museum of Bergen, Box 7800, NO –5020 Bergen, Norway. Abstract: We estimated phylogeny in the lichen-forming ascomycete family Pannariaceae. We specifically modelled spatial (across-site) heterogeneity in nucleotide frequencies, as models not incorporating this heterogeneity were found to be inadequate for our data. Model adequacy was measured here as the ability of the model to reconstruct nucleotide diversity per site in the original sequence data. A potential non-orthologue in the internal transcribed spacer region (ITS) of Degelia plumbea was observed. We propose a revised generic classification for the Pannariaceae, accepting 30 genera, based on our phylogeny, previously published phylogenies, as well as morphological and chemical data available.

We suggest a method of constructing red numbers for plant species, in order to set priorities in con- servation policy. The red number is an additive index, summarising values of four parameters: 1. Rarity – The number of sites (1 km2) where the species is present. A rare species is defined when present in 0.5% of the area or less. 2. Declining rate and habitat vulnerability – Evaluate the decreasing rate in the number of sites and/or the destruction probability of the habitat. 3. Attractivity – the flower size and the probability of cutting or exploitation of the plant. 4. Distribution type – scoring endemic species and peripheral populations. The plant species of Israel were scored for the parameters of the red number. Three hundred and seventy (370) species, 16.15% of the Israeli flora entered into the “Red List” received red numbers above 6. “Post Mortem” analysis for the 34 extinct species of Israel revealed an average red number of 8.7, significantly higher than the average of the current red list.

  • Reconstructing Palaeoenvironments of the White Peak Region of Derbyshire, Northern England
    THE UNIVERSITY OF HULL Reconstructing Palaeoenvironments of the White Peak Region of Derbyshire, Northern England being a Thesis submitted for the Degree of Doctor of Philosophy in the University of Hull by Simon John Kitcher MPhysGeog May 2014 Declaration I hereby declare that the work presented in this thesis is my own, except where otherwise stated, and that it has not been previously submitted in application for any other degree at any other educational institution in the United Kingdom or overseas. ii Abstract Sub-fossil pollen from Holocene tufa pool sediments is used to investigate middle – late Holocene environmental conditions in the White Peak region of the Derbyshire Peak District in northern England. The overall aim is to use pollen analysis to resolve the relative influence of climate and anthropogenic landscape disturbance on the cessation of tufa production at Lathkill Dale and Monsal Dale in the White Peak region of the Peak District using past vegetation cover as a proxy. Modern White Peak pollen – vegetation relationships are examined to aid semi- quantitative interpretation of sub-fossil pollen assemblages. Moss-polsters and vegetation surveys incorporating novel methodologies are used to produce new Relative Pollen Productivity Estimates (RPPE) for 6 tree taxa, and new association indices for 16 herb taxa. RPPE’s of Alnus, Fraxinus and Pinus were similar to those produced at other European sites; Betula values displaying similarity with other UK sites only. RPPE’s for Fagus and Corylus were significantly lower than at other European sites. Pollen taphonomy in woodland floor mosses in Derbyshire and East Yorkshire is investigated.
