“…1). Mean annual rainfall in Biu is about i000 mm/a with a wet season (May-October) of about 160 days (Tuley 1972). According to White (1983) the vegetation of the Biu Plateau can be characterised as undifferentiated woodland of the Sudanian zone, whereas Keay (1959b) attributes this region to the northern Guinea zone.…”

“…the taller plants produced with shelters often showed reduced stem calipers (tuley 1981;Smith 1983;lantagne et al 1990;Kjelgren 1994;Burger et al 1996). Sometimes a smaller root system was produced, causing potential stability problems for the plants after removing the shelter (Potter 1991 ;Burger et al 1992;mayhead & Jenkins 1992;mayhead & Boothman 1997).…”

A 3-year study was conducted to evaluate the effects of tree shelters on young olive (Olea europaea) tree growth and physiology. The trial was carried out in the Apulia region in southern Italy using 1-year-old plants of the cultivar 'Coratina'. Four different types of polypropylene shelters were tested: 75-cm-high brown; 90-cm-high brown; 75-cm-high green; 120-cm-high light-green vented, with holes in their basal part. Both green shelters significantly increased the vertical growth of the trees, especially the 120-cm light-green vented ones. Shelters did not increase the amount of dry matter produced, but they modified its allocation within the tree, favouring vertical growth and the development of shoots in the apical parts of the trees.

“…At the highest elevations are moorlands (Callunadominated heaths) managed by burning to favour conditions for red grouse (Lagopus lagopus), and also deer stalking. The forest history refl ects that of the region with a long history of management and use of clearfelling and replanting as the main form of management (Tuley 1987). As early as 1507 forest rights were being granted to land-owners in Strathdon (Matthews 1976), treeplanting was recorded from 1745, and by 1792 there were 'no natural woods of any consequence' (Anderson 1967).…”

Ray, D.2002. An approach to predicting the potential forest composition and disturbance regime for a highly modifi ed landscape: a pilot study of Strathdon in the Scottish Highlands. Silva Fennica 36(1): 233-247.The existing native forests of Scotland are fragmented and highly modifi ed and none are 'natural'. There is considerable interest in expanding the area of this oceanic boreal forest and restoring forest habitat networks to benefi t biodiversity. However, unlike regions with substantial remaining natural forest, it is diffi cult to provide reference values for forest composition and structure using methods related to historical variability. An alternative approach is to combine models that predict woodland type from knowledge of site conditions, and disturbance regime from knowledge of the disturbance agents (particularly abiotic agents).The applicability of this approach was examined as part of a public participatory planning exercise in a highly managed landscape in Eastern Scotland. Models of site suitability (Ecological Site Classifi cation) and wind disturbance (ForestGALES) were combined to determine potential woodland composition and structure, and derive options for native woodland expansion. The land use of the upper Strathdon catchment is currently dominated by agriculture and planted forests of non-native species, and only small fragments of semi-natural woodland remain (< 0.5% of the land area). Model results indicated that a very substantial proportion of the land area could support woodland (> 90%) but of a restricted range of native woodland types, with Scots pine communities predominant. Structural types likely to be present included wind-induced krummholz (treeline) forest, forest with frequent stand replacement by wind, and also a large area where gap phase (or some other disturbance) would predominate. The merits of the approach are discussed, together with the diffi culties of validation, and the implications for the management of existing forests.
