Summary Bilberry (Vaccinium myrtillus L.) is a prominent species in moorland and woodland vegetation which spreads and survives mainly by vegetative growth from buds. Each berry contains many seeds but seedlings are rarely seen in Scotland. Thus, it is of interest to establish whether the lack of seedlings reflects a low production of viable seeds, their dormancy status, or germination requirements or seed longevity. Samples of V. myrtillus berries were collected from moorland in the east Grampian mountains, Scotland. Each berry contained about 70 seeds. Small seeds did not germinate but large fresh seeds achieved over 80% germination in laboratory tests. Seeds stored dry for one year did not lose viability. Seedsstored in moist cold conditions (to mimic conditions in the soil over winter) lost viability progressively and none germinated after about 43 weeks. Germination occurred over the range 15–24°C. These seed germination and longevity characteristics may currently severely limit the window of opportunity for germination of seeds of V. myrtillus in Scotland and have implications for the spread of V. myrtillus if average temperatures increase.
越橘(Vaccinium myrtillus L.)是沼地和林地植被中的一种重要植物,主要通过芽性营养生长进行传播和生存。每个浆果都含有许多种子,但在苏格兰很少见到幼苗。因此,确定幼苗的缺乏是否反映了可活种子的低产量、它们的休眠状态、萌发要求或种子寿命是有意义的。在苏格兰格兰扁山东部的沼地中采集了桃金娘的浆果样本。每个浆果含有大约70颗种子。小种子不发芽,但大新鲜种子在实验室试验中萌发率超过80%。干燥储存一年的种子没有失去活力。储存在潮湿寒冷条件下的种子(模拟冬季土壤条件)逐渐失去活力,大约43周后没有发芽。萌发发生在15-24°C范围内。这些种子萌发和寿命特征可能严重限制了苏格兰myrtillus种子萌发的机会窗口,并且如果平均温度升高,对myrtillus的传播有影响。

Summary There is a range of legislation and policy relating to plant conservation in Scotland, including international, European and domestic measures (Scottish Office, 1998). There are, in addition, opportunities and challenges for plant conservation as a result of devolution. This paper reviews examples taken from the range of current policies and laws to illustrate both where these have been beneficial and where they have not been so successful for plant conservation, and offers some views on what lessons have been learnt from these actions.
苏格兰有一系列与植物保护有关的立法和政策,包括国际、欧洲和国内措施(苏格兰办事处,1998年)。此外,权力下放给植物保护带来了机遇和挑战。本文回顾了从现行政策和法律中选取的例子,以说明这些政策和法律在哪些方面对植物保护有益,哪些方面不太成功,并就从这些行动中吸取的教训提出了一些看法。

Summary Back from the Brink is Plantlife's practical conservation response to the current crisis of species loss and decline in Britain, targeting the wild plants and habitats that are seriously threatened in Scotland. It currently includes 59 species of vascular and lower plants in Scotland, most of which are also biodiversity priority species under the UK Biodiversity Action Plan. The programme combines laboratory and field research with hands-on management to achieve effective action for rare and threatened plants. Examples of action for three priority species are given: Linnaea borealis L., Pilularia globulifera L. and a group of stipitate hydnoid fungi. A major distribution study has been undertaken of Pilularia globulifera and positive conservation management has been undertaken at several sites. Work on the genetics of Linnaea borealis has given insights into its conservation management, and recent felling of timber in one plantation has provided a significant opportunity to learn more about the ecological requirements of the species. A recent national survey of stipitate hydnoid fungi has led to proposals for further research into the ecological requirements of this group. Plantlife's priorities for future work are outlined, including the launch of a new conservation forum, Plantlife Link Scotland.
Back from the Brink是Plantlife针对当前英国物种丧失和衰退危机的实际保护回应,目标是苏格兰受到严重威胁的野生植物和栖息地。它目前包括苏格兰的59种维管植物和低等植物,其中大多数也是英国生物多样性行动计划下的生物多样性优先物种。该计划将实验室和实地研究与实际管理相结合,以实现对稀有和受威胁植物的有效行动。给出了三个优先物种的作用实例:北方Linnaea borealis L.,毛毛菌globulifera L.和一组具刺的水螅真菌。对毛毛菌的分布进行了重大研究,并在若干地点进行了积极的养护管理。对北方林的遗传学研究使人们对其保护管理有了深入的了解,最近在一个种植园砍伐木材为了解该物种的生态需求提供了一个重要的机会。最近的一项关于棘齿水螅类真菌的全国调查提出了进一步研究这一群体的生态需求的建议。Plantlife未来工作的重点是概述,包括启动一个新的保护论坛,Plantlife Link Scotland。

Summary The paper reports demographic studies of the endemic Cerastium nigrescens and the very rare Arenaria norvegica ssp. norvegica on the Keen of Hamar ultramafic outcrop on Unst, Shetland from June 1994 to November 1996. Plants of Cerastium nigrescens showed a Deevey type II curve and mature plants had a half-life of 3.8 years. Plants of Arenaria norvegica ssp. norvegica showed a Deevey type I curve with high mortality after flowering in the second year. There was some evidence of increased mortality during droughts but this had little impact on the total population. Seed production and seedling recruitment for both species was good throughout the study period. Seed bank measurements ranged from 12–13 m2 for Cerastium nigrescens and 24–43 m-2 for Arenaria norvegica ssp. norvegica. The study showed that there was no immediate threat to the populations of the two species but because of their isolated occurrence they are susceptible to extinction and should be carefully monitored.

Contexts, developing ideas and emerging issues in the conservation management of the RSPB Abernethy Forest Reserve 英国皇家鸟类保护协会阿伯内西森林保护区的环境、发展思路和新出现的问题
Pub Date : 2003-01-01 DOI: 10.1080/03746600308685055

Summary Native pinewoods are fragmentary in extent and floristic integrity. In maintaining and extending these remnants, managers should recognise the diversity of potential communities and the unique mix of species in their flora. At the RSPB Abernethy Forest Reserve management aims to develop a self sustaining forest of natural character over the potential woodland area. A present-natural forest provides one model for the attributes and processes, which this forest should contain. Habitat management experiments have recently commenced investigating ways of increasing blaeberry Vaccinium myrtillus in forest areas, and increasing tree regeneration at the forest edge. The possible wider role of management intervention in pinewoods is discussed.
本土松林在范围和区系完整性上都是支离破碎的。在维护和扩展这些遗迹时,管理者应该认识到潜在群落的多样性和植物区系中物种的独特组合。在皇家鸟类保护协会阿伯内西森林保护区,管理的目标是在潜在的林地地区开发一个自我维持的自然特征的森林。现在的自然森林为这个森林应该包含的属性和过程提供了一个模型。生境管理实验最近开始研究如何在森林地区增加越橘,并在森林边缘增加树木更新。讨论了松林管理干预可能发挥的更广泛作用。

Plant chromium toxicity on Summerford Bing, Falkirk, central Scotland 苏格兰中部福尔柯克的萨默福德冰上的植物铬毒性
Pub Date : 2003-01-01 DOI: 10.1080/03746600308685007
L. Paterson, James R. Anderson, J. Proctor
Summary Summerford Bing is an old industrial site near Falkirk which was contaminated from about1860–1970 by chemical and other works. The industrial wastes were redistributed in a spoil heap about 300 m × 300 m in area. Drainage water from the heap was known to have high concentrations of chromium. An attempt to establish birch on the spoil heap's slopes has been partially successful but many of the trees were very stunted. Soil analyses showed that hexavalent chromium toxicity was the most likely cause of the poor birch growth and this was confirmed by an experiment on birch seedlings. Acute plant chromium toxicity is a rare phenomenon in Britain where it is always associated with anthropogenic soils. The possibility of the site's toxicity to humans is discussed and it is concluded that the site is potentially hazardous to health.
Summerford Bing是福尔柯克附近的一个老工业区,从1860年到1970年被化学和其他工程污染。将工业废弃物重新分布在面积约300 m × 300 m的废渣堆中。众所周知,从堆中排出的水含有高浓度的铬。在废土堆的斜坡上种植桦树的尝试取得了部分成功,但许多树木都非常矮小。土壤分析表明,六价铬毒性是导致桦树生长不良的最可能原因,并通过对桦树幼苗的实验证实了这一点。急性植物铬毒性在英国是一种罕见的现象,它总是与人为土壤有关。讨论了该场地对人类毒性的可能性,并得出结论认为该场地对健康有潜在危害。

Fungal conservation in Scotland: Recent progress and future priorities 苏格兰的真菌保护:最近的进展和未来的优先事项
Pub Date : 2003-01-01 DOI: 10.1080/03746600308685047

Summary In recent years, fungal conservation in Scotland has made substantial progress, particularly as a result of field surveys undertaken in support of the Biodiversity Action Plans developed for selected species. Results are presented from four recent surveys: (i) fungal diversity in conifer plantations, (ii) hydnoid (‘tooth’) fungi in coniferous forests, (iii) grassland fungi, (iv) fungal survey of the Mar Lodge Estate. These surveys have substantially improved knowledge of the conservation status of a number of threatened taxa, and have also provided insights into patterns of fungal diversity at a range of scales. The results indicate that some of the fungal communities of Scotland, such as those associated with unimproved grasslands, are of international conservation importance. The implications of the survey results for conservation management are discussed, and suggestions are made regarding priorities for future work. In particular, there is a need to provide conservation managers with guidance on how fungal conservation can be achieved in practice.
近年来,苏格兰的真菌保护取得了实质性进展,特别是在支持选定物种的生物多样性行动计划的基础上进行的实地调查。结果来自最近的四项调查:(i)针叶林的真菌多样性,(ii)针叶林的齿状真菌,(iii)草地真菌,(iv)马洛奇庄园的真菌调查。这些调查大大提高了对一些受威胁分类群的保护状况的认识,并提供了对各种尺度真菌多样性模式的见解。结果表明,苏格兰的一些真菌群落,如那些与未改良草地有关的真菌群落,具有国际保护意义。讨论了调查结果对保护管理的影响,并就未来工作的重点提出了建议。特别是,有必要为保护管理人员提供指导,如何在实践中实现真菌保护。

Summary The paper describes the status of surviving montane willow scrub on or adjacent to Ben Lawers NNR, referring to eight species of willow and juniper. Most of these have no viable future on the Reserve. The evidence and reasons for decline are discussed, and the conservation work initiated since 1987 described, including its rationale and the associated objective problems. Intervention with fencing and planting is intended to test the feasibility of restoring a viable scrub community, with the proximate objective of reestablishing seed-producing populations of the respective species. The long term and uncertain nature of the work is discussed. Plant names used are according to Stace (1991).

Summary The blanket bogs of Caithness and Sutherland are the finest examples of their type in the world. Restricted to a few parts of the world where cool, oceanic climatic conditions prevail, Britain holds approximately 13% of the total global resource of blanket bog, of which the bogs of Caithness and Sutherland form the largest and most intact area. In recent times, extensive areas of the peatlands of Caithness and Sutherland have been damaged – principally through drainage and forestry. In 1994, the Royal Society for the Protection of Birds (RSPB) purchased Forsinard Estate in the heart of the peatlands as part of a EU LIFE funded project on blanket bog conservation. In partnership with Scottish Natural Heritage and Caithness and Sutherland Enterprise, this four year RSPB led project promoted a number of initiatives on awareness raising and ecotourism as well as a range of practical demonstrations on restoring damaged blanket bog. More recently, a follow up LIFE Peatlands Project was launched in 2001 where RSPB extended the partnership to include SNH, Forest Enterprise, Plantlife and the Forestry Commission. This paper gives an over-view of the partnership approach to the management and restoration of damaged blanket bog in Caithness and Sutherland.
凯斯尼斯和萨瑟兰的地毯式沼泽是世界上这种类型的最好的例子。英国的地毯式沼泽资源仅占全球地毯式沼泽资源的13%,其中凯斯尼斯和萨瑟兰的沼泽面积最大,也是保存最完整的地区。最近,凯斯内斯和萨瑟兰的大片泥炭地遭到破坏-主要是由于排水和林业。1994年,英国皇家鸟类保护协会(RSPB)购买了泥炭地中心的福西纳德庄园,作为欧盟生命基金会资助的地膜沼泽保护项目的一部分。在与苏格兰自然遗产、凯斯尼斯和萨瑟兰企业的合作下,RSPB领导的这个为期四年的项目促进了一系列关于提高意识和生态旅游的倡议,以及一系列关于恢复受损毯沼泽的实际示范。最近,2001年启动了一个后续的泥炭地项目,RSPB将合作伙伴关系扩大到包括SNH,森林企业,植物生命和林业委员会。本文概述了在凯斯内斯和萨瑟兰被破坏的毯状沼泽管理和恢复中的伙伴关系方法。
