The social negotiation of nature conservation policy: conserving pinewoods in the Scottish Highlands

This paper examines the social and cultural processes through which conservation policy is derived. Focusing on the management of pinewoods in Abernethy Forest, Scotland, it explores the cultural politics involved in developing appropriate management practice. Calling upon participant observation, semi-structured interviews with site managers and the analysis of texts, it traces the gradual moves from a policy of minimum intervention towards more complex management regimes. The paper explores the social construction of the forest’s naturalness that underpinned the early policy of minimum intervention and then the ways that the forest was reconstructed as the managers debated the merits of minimum intervention and the degree to which they should intervene. The paper illustrates how managers have considered different forms of intervention and how they have tried to balance their concern with the naturalness of the forest with a need to intervene on behalf of particularly important species. It highlights the importance of conservationists’ culturally derived understandings of nature and suggests that an awareness of these cultures of nature is vital if conservationists are to develop robust policies.

Distribution and importance of the lichen vegetation of the Scottish Highlands

Summary

The mountains of the Western Highlands of Scotland support a lichen vegetation that is apparently unique in Europe, and probably the world. This lichen vegetation consists mainly of microlichens and is important both intrinsically, with a number of rare and apparently endemic taxa and communities, and as a major contributor to the botanical biodiversity of the ecosystem. By contrast, the lichen vegetation of the Eastern Highlands, which consists mostly of terricolous macrolichens, is best considered a fragmented, species-poor outlier of that present in Scandinavia and is of national interest only.     

Red deer range and problems of carrying capacity in the Scottish Highlands

Some general principles underlying the concept of carrying capacity and problems in using the term are illustrated by reference to herbivore/vegetation inter-relationships in intensive pasture systems, regimes of range management and wildlife systems. The approach to management of the deer/range system in Scotland does not fit into any of these categories of land use. Ecological deficiencies arise because deer, rather than the soils and vegetation, are regarded as the resource. Hence, management of the range is animal orientated. It is based on techniques such as burning which give temporary benefits to the animal component of the system. It is argued that this inversion of priorities in management has the long-term effect of encouraging vegetational successions that aggravate problems of animal management, especially on the poorer soils. The characteristics of the deer and the vegetation, and trends of change are considered in this context. It is concluded that within the present framework of management there is little scope for radical improvement. A restructuring of the system is required to give greater control over the biological performance of the deer and of the trends in the vegetation.     

Factors influencing nuisance blackfly (Diptera: Simuliidae) activity in the Scottish Highlands

Abstract. The nuisance activity of blackflies (Diptera: Simuliidae) was investigated in several habitats on Speyside, near Kincraig (57^o08'N, 3^o56'W), Invernesshire, in central Scotland during May-October 1987-89.
The main blackfly species caught landing/biting on humans were Simulium reptans, S. argyreatum, S. variegetum and the S. tuberosum complex, in order of prevalence. Blackfly biting activity occurred from mid-May to mid-September. Numbers of female blackflies attracted to volunteers were correlated with their body posture, habitat and the season. Overall, Simulium activity was greatest in mixed birch/juniper forest, least in spruce plantations and at intermediate levels on pasture, moorland and in Scots Pine forest.
Compared with an adult, a child experienced twice as many Simulium bites per hour (12.2 v 6.3) in the birch forest. On the child's body, 69% of blackfiies landed on the head, neck and back, whereas the majority landed on the legs (48%) and arms (28%) of adults. Bending over, especially during the exertion of gardening, was more attractive to anthropophilic blackfiies than standing or kneeling.     

Conservation with a Gun: Understanding Landowner Attitudes to Deer Hunting in the Scottish Highlands

Conservation conflicts are often difficult to resolve due to a combination of poorly defined property rights, inadequate funding, high transaction costs, and contrasting value systems among stakeholders. This paper explores these barriers to collaboration in the context of the emerging deer crisis in the Scottish Highlands, where deer numbers are now higher than at any time in recorded history. In particular we explore the potential role of recreational hunting in the government’s strategy to contain rising deer numbers from the landowners’ perspective. Using both qualitative and quantitative analysis we find that hunting traditions and personal preferences, reinforced by antipathy to conservationists and their perceptions of land stewardship, are the major barriers to shooting more deer for conservation objectives. We conclude that an expansion of commercial hunting opportunities is the best practical approach to resolving the current conflict over deer, but conservationists and landowners must work together to create a more positive context for hunter-conservation initiatives and activities.

Blanket peat in the Scottish Highlands: timing, cause, spread and the myth of environmental determinism

This contribution describes the geomorphic, stratigraphic, palaeoclimatic, palaeoecological and ¹⁴C dating evidence for the timing within the present interglacial of blanket peat initiation and extension (‘spread’) from five localities throughout the upland and northern regions of Scotland. The results suggest that blanket peat was common or abundant over much of the highland landscape within a few thousand years of the beginning of the Holocene period. Blanket peat developed either as an inevitable but rapid end-stage to soil development in this generally cold and wet climate or was promoted by climatic change. There is no evidence from this data-set that blanket peat developed as a result of anthropogenic activities. It is suggested, indeed, that farming communities successfully resisted the natural spread of peat across their fields.     

Metal content in insects associated with ultramafic and non-ultramafic sites in the Scottish Highlands

1. Concentrations of magnesium, manganese, chromium, and cadmium were measured in Coleoptera, Diptera, Hemiptera, and Hymenoptera captured at ultramafic and non-ultramafic sites in the Highlands of Scotland. 2. The Hemiptera showed the greatest concentration differences between the ultramafic and non-ultramafic sites in manganese, magnesium, and chromium, with greatly increased levels in ultramafic sites. 3. The Coleoptera and Hymenoptera had lower levels of manganese, magnesium, and chromium at the ultramafic site than at the non-ultramafic sites. The Diptera had increased levels of manganese and magnesium at the ultramafic site, but showed no difference in chromium levels from any site. 4. Cadmium occurred at lower levels in all insect orders at the ultramafic site.     

Can Economic Incentives Resolve Conservation Conflict: The Case of Wild Deer Management and Habitat Conservation in the Scottish Highlands

Market-based economic incentives are increasingly perceived as a cost-effective approach to biodiversity conservation but empirical evidence to substantiate this claim is lacking. Using both qualitative and quantitative data analysis this paper investigates the potential role of market incentives to increase venison production as a mechanism to resolve conflicts over wild red deer management in the Scottish Highlands. Our analysis suggests the approach is unlikely to be effective because investments in venison production would bring conflict with more important non-pecuniary objectives of landownership such as ‘sporting quality’ and ‘exclusivity’. At a broader level we urge caution when considering the deployment of economic instruments to resolve contemporary conservation conflicts where profit maximisation is not the dominant objective and/or where the target group is extremely wealthy.     

Assessment of terrain sensitivity on high plateaux: a novel approach based on vegetation and substrate characteristics in the Scottish Highlands

Background: High plateaux in the Scottish Highlands are vulnerable to disturbance and erosion, but there is a lack of quantitative measurements of terrain sensitivity.

Aims: To apply new quantitative methods to assess the sensitivity of such terrain to physical stress.

Methods: We investigated two components of the mechanical properties of the terrain on 10 plateaux underlain by several different lithologies: the tensile strength of the vegetation mat and underlying root zone, and the shear and compressional strengths of the substrate.

Results: Significant differences in tensile strength occur amongst plant communities, but there is also large within-site and between-site variation for particular communities. A significant component of such variability is attributable to the proportional representation of co-dominant species within communities, and inter-site variability is partly explained by substrate granulometry: particular communities exhibit lower strength characteristics when rooted in sandy substrates derived from coarse-grained lithologies than the same communities on silt-rich soils derived from fine-grained lithologies.

Conclusions: Terrain sensitivity to physical stress is conditioned by the interaction of vegetation and substrate characteristics. Generally, grass-dominated (particularly Nardus-dominated) communities tend to be most robust, and communities dominated by bryophytes and prostrate Calluna vulgaris are typically most sensitive. We identify a continuum of substrate strength: peat is the most sensitive substrate type, followed by other organic-rich soils, sandy matrix-supported substrates and silt-rich matrix-supported substrates. Clast-supported substrates and openwork blockfields are the most robust substrate types. Because the near-surface layers of mineral substrates are weakest, erosion is likely to remove these to expose the underlying robust but sterile clast-supported layers, altering soil status and inhibiting plant recolonisation on eroded substrates.     

Prefigured Features: A view from the New Guinea Highlands

Stimulated by a conference on Portraiture and the Problematics of Representation, which aimed to address portraiture as a set of cultural practices under the rubric of ‘any body-representation that stands for an individual’, in this paper I ask some questions raised by materials from Papua New Guinea. I begin with an investigation of the notion of individuation in relation to the heads which are taken in Asmat and Marind-Anim headhunting. I argue that if anyone's individuality is represented by a captured head it is that of the new owner, not his deceased victim. I then turn to Hagen feather plaques and suggest that they are best understood as assemblages of material resulting from mobilising relations, and hence not as portraits embodying notions of likeness.     

Creating Difference: A Contemporary Affiliation Drama in the Highlands of New Guinea

Issues of affiliation to groups, important in Papua New Guinea Highlands ethnography during the 1960s and 1970s, have since been overshadowed by other analytical concerns. But the issues have never gone away and they resound clearly in the life of people there, who are dealing with situations of rapid change that make the crafting of affiliations problematic and strategically important. We examine a case in which an affiliation event was staged in order to mediate between inter-ethnic claims on a child and to refurbish practices of securing these claims in the absence of brideprice payments or virilocal residence. The analysis points out how transactions that the actors engaged in fell ambiguously between the categories of gift and commodity, and how ties of nurturance and food-giving continue to play a crucial part in representations and negotiations. At the core of the event was the extent to which the parties involved shared in the understandings of the event at hand. This underlines the fact that transactions and meanings are always inextricably liinked together. Strategies ar made meaningfully and meanings are made strategically.     

Biotic diversification in the Guayana Highlands: a proposal

Until recently, the high degree of diversity and endemism of the Guayana Highlands was explained within the frame of the refuge theory. Although this hypothesis is unsupported by recent palaeoecological evidence, no new diversification model has been proposed. This paper is a proposal based on the latest palynological findings that indicate a downward biotic migration of c. 1100 m altitude during glacials, and the subsequent interglacial upward shift, in response to colder and warmer climates, respectively. Therefore, during glacials, biotic mixing is expected in the lowlands, thus promoting sympatric speciation, hybridization and polyploidy. At the mountaintops, unknown cold‐adapted taxa and páramo‐like(?) communities are expected to have occurred, and vicariance prevailed. In the interglacials, many taxa have had the opportunity for ascending to the mountains again, allowing genetic interchange among their slopes and summits, while others would have been adapted to lowlands. The interglacial highland communities, where vicariance still predominated, experienced some extinction owing to habitat loss by upland displacement. According to this model, the successive alternation of glacials and interglacials resulted in a net increase of diversity and endemism, favoured by the complex topography and habitat heterogeneity, which allowed high niche diversification. This model has some similarities with the Andean and Amazon modes of diversification, but the special topographical characteristics of the Guayana region made it different in other fundamental aspects. The Guayana Highlands would have acted as a ‘biodiversity pump’ for the surrounding inner and coastal lowlands, due to the repeated speciation and further spreading events, as a response to climate. Several working hypotheses are suggested in relation to the proposed model. The use of coordinated international multiproxy projects combining palaeoecology and genetic analysis of modern taxa is strongly encouraged for exploring these ideas.     

Spring phenology shows genetic variation among and within populations in seedlings of Scots pine (Pinus sylvestris L.) in the Scottish Highlands

Background: Genetic differentiation in phenotypic traits is often observed among forest tree populations, but less is known about patterns of adaptive variation within populations. Such variation is expected to enhance the survival likelihood of extant populations under climate change.

Aims: Scots pine (Pinus sylvestris) occurs over a spatially and temporally heterogeneous landscape in Scotland. Our goal was to examine whether populations had differentiated genetically in timing of bud flush in response to spatial heterogeneity and whether variation was also maintained within populations.

Methods: Two common-garden studies, involving maternal families of seedlings from 21 native pinewoods, were established and variation in the trait was measured at the beginning of the second growing season.

Results: Populations showed genetic differences in the trait correlated with the length of growing season at their site of origin, but the majority of variation was observed within populations. Populations also differed in their levels of variation in the trait; a pattern that may be influenced by spatial variation in the extent of temporal climate variability.

Conclusions: Our findings suggest that populations have adapted to their home environments and that they also have substantial ability to adapt in situ to changes in growing season length.
