Scots pine is one of only three native conifers found in the UK and our only true cone-bearing tree. Although Scots pine can trace its earliest British ancestry back to the end of the Ice Age, it is something of an anomaly in that relatively few of the trees living today are directly descended from those early colonisers. Originally forming extensive forests over most of Britain, a change in the climate to warmer temperatures some 5000 years ago favoured deciduous trees and pushed the range of the Scots pine northwards, out of most of England and Wales. In the seventeenth century, a combination of tree-felling for industrial use and the notorious Highland clearances all but eradicated the tree in northern Scotland. There was estimated to be little more than 10,000 hectares of native Scots pine forest left in Scotland by the 1970s. This tree can grow as high as 40 metres and often has a trunk that is extensively forked. The bark is reddish-brown and forms flaky plates. In common with other pines, the tree bears stiff waxy needles instead of flattened leaves. These grow in pairs from the twigs and are between five and seven centimetres long. The tree also bears its seeds in cones, small egg-shaped woody structures which appear green and resinous in their first year, later drying to produce the familiar mini-pineapple shaped pinecones from which the seeds are dispersed.

Scots pines shed their pollen in May in copious amounts. The male pollen-producing flowers are located at the base of new shoots. The female cones grow at the tips of stronger new shoots and, once fertilised, ripen after two years. The needles are not shed each year but remain on the tree for two or even three years. Their waxy coating protects against excessive water-loss and the needles have fewer pores than the leaves of deciduous trees. Pines seal damage to their trunks and branches by producing resin; a sticky, viscose secretion that protects the tree against entry by insects and fungal spores. This resin sometimes traps unwary creatures and preserves them. When this resin becomes hard it forms amber, sometimes surviving for millions of years, and can provide a unique record of the insect life that lived in the ancient pine forests. Artists and craftsmen have also found pine a useful source of raw materials. The resin can be refined and the volatile component, turpentine, is used as a solvent. The remaining constituent, rosin, has been used to coat zinc or copper plates used in printing engraved images, and for dressing violin bows. The timber, though classified as 'softwood', is strong and used for a huge range of products, from house and boat-building to furniture, toys and railway sleepers. Once treated with preservative, it weathers well and lasts for years. Many square hectares of pine forest are planted each year to supply industry with timber. The sweet fragrance of pine has even found its way into our homes in the form of scented cleaning products!

The Scots pine is the only pine species native to Northern Europe. These pines can live for centuries. In 2006, one of the oldest known Scots pines (estimated age between 355 and 405 years) fell to the ground in the town of Wolfheze (Province of Gelderland). However in the wadden region, these trees are usually cut down after 80 to 120 years. There is too much salty wind for them to reach a ripe old age. Scots pine is the only native pine to northern Europe. It requires so little food that it even grows on humus-poor wind-blown sand. You find them mostly on the sheltered side of dune woods.

This introduced pine is often cultivated because of its evergreen foliage and decorative seed cones. Large specimens of this species, in particular, have orange-red bark along the upper trunk and larger branches that is especially striking. The length of the needle-like leaves is rather variable across different specimens; young fast-growing trees tend to have longer leaves than older slow-growing trees. Different varieties of Scots Pine have been described in Eurasia; the description here applies to the typical variety (var. sylvestris). In North America, this is the variety of Scots Pine that is commonly encountered among the various cultivars. Scots Pine can be distinguished from other Pinus spp. (Pines) from a combination of the following characteristics

This tree is 50-100' tall at maturity, consisting of a single trunk and a rather broad irregular crown. The trunk is often crooked, but sometimes it is straight. The crown can be conical-ovoid to ovoid in shape with widely spreading to ascending lateral branches. The density of these branches varies with the growth of the tree. Trunk bark at the base is reddish gray and shallowly furrowed or fissured, while the thin bark of the upper trunk and major branches is orange-red and flaky. Young twigs are light brown and covered with needle-like leaves, but they become more gray and scaly in appearance with age. The needle-like leaves occur in clusters of 2 along the twigs; they are 1¼–3½' long, gray-green or blue-green, and twisted. The leaves are evergreen, remaining on the tree for 2-7 years (a shorter period of time for warm climates as opposed to cold climates). The upper surface of each leaf is slightly concave, while the lower surface is convex; there are 4-6 white lines that run along the length of the lower surface.

Scots pine ranges across Europe and Asia, from the Iberian peninsular and Turkey in the south to the edge of the Siberian tundra. It has also been introduced to other countries.

Scots pine is the most widely distributed pine in the world. It's
native range includes Scotland, Scandinavia (excluding Denmark),
northern Europe, and northern Asia. It is introduced in many areas in
the United States and Canada, and is naturalized in the Northeast and in
the Great Lakes states [29,32,42].

Scots Pine has naturalized in only a few counties in Illinois, where it is uncommon (see Distribution Map). These naturalized populations tend to persist only in sandy areas. Typical habitats include sandy upland forests, sandy savannas, upland rocky woodlands, and open disturbed areas near cities and suburbs. Sometimes Scots Pine can be found in tree plantations and it is often used as a landscape plant. This tree was introduced into the United States from Eurasia.

More info for the term: tree

Scots pine is an exotic, medium-sized, two-needle pine. Height at
maturity usually ranges from 50 to 100 feet (15-30 m) [18,42]. The
crown is open and spreading. Needles range from 1.8 to 3.6 inches
(4.5-9.0 cm) in length [57]. The bark is relatively thin [18,57]. A
taproot is frequently developed on sandy soils, but is not a universal
trait for Scots pine. The depth of the taproot ranges from 4.9 to 9.8
feet (1.5-3.0 m), but most of the roots are horizontal and within 7.8
inches (20 cm) of the soil surface [42]. A population of middle-aged
Scots pine in Finland had numerous root grafts between neighboring
trees in networks of up to ten trees. Water and nutrients are
transferred from one tree to another through the grafts (Yli-Vakkuri in
[9]).

Scots pine is long-lived; individuals of nearly 1,000 years of age
occur in northern Sweden [59]. Ages of 200 and 400 years are common in
Scandinavia [22].

More info for the term: peat

Scots pine is found from sea level to 8,000 feet (2,440 m) elevation,
and grows on a wide variety of soils including peat, though growth on
peat usually results in stunted trees [42]. Growth is best on
well-drained soils [29]. Soil pH ranges from 4.0 to 7.0, but growth is
best between 4.5 and 6.0 [42,56].

Where it is naturalized in northern New York, Scots pine is associated
with black cherry (Prunus serotina), red maple (Acer rubrum), sugar
maple (A. saccharum), American beech (Fagus grandifolia), quaking aspen
(Populus tremuloides), and eastern white pine [42].

Scots Pine, like other pines, is a food source of many insects. This includes the caterpillars of the butterfly Callophrys niphon (Pine Elfin), the caterpillars of several moths, Pineus strobi (Pine Bark Adelgid), Toumeyella pini (Striped Pine Scale), the aphids Cinara pini and Eulachnus rileyi, Aphrophora parallela (Pine Spittlebug), a few plant bugs, Tomicus piniperda (Common Pine Shoot Beetle), the larvae of several long-horned beetles, larvae of the metallic wood-boring beetles Buprestis lineata and Chrysobothris cribraria, and the larvae of several weevils. The Insect Table lists many of these species. Vertebrate animals, particularly birds and mammals, make use of pine trees in various ways. The seeds and/or buds are eaten by some upland gamebirds and songbirds. These species include the Wild Turkey, Bobwhite Quail, Red-Bellied Woodpecker, Mourning Dove, Black-Capped Chickadee, Carolina Chickadee, Brown Creeper, Red-Breasted Nuthatch, White-Breasted Nuthatch, Pine Grosbeak, Red Crossbill, White-Winged Crossbill, Slate-Colored Junco, Pine Siskin, Common Redpoll, Monk Parakeet (in urban areas), and Pine Warbler. The seeds are also eaten by the Red Squirrel, Gray Squirrel, and White-Footed Mouse, while the foliage and twigs are browsed by White-Tailed Deer and Elk. Pines are favored nesting sites for some birds; these species include the Pine Warbler, Yellow-Throated Warbler, and Blue-Headed Vireo. Because the evergreen leaves provide good cover, the Evening Grosbeak, migrating Robins, various owls, and other birds use these trees as roosting sites.

More info for the term: fire exclusion

Fires in Sweden have given rise to uneven-aged stands of Scots pine,
particularly in virgin types that have not been disturbed by humans
[59]. Fire exclusion in Europe has resulted in a conversion of
pine-dominated forests (including Scots pine) to hardwoods [26].

Prescribed burning followed by tilling, followed by natural
reforestation (known as swaling), has been practiced in Europe for many
years. It has been noted that the more frequently a site has been
swaled, the more likely it is that hardwoods will regenerate on the
site. Sites that have been burned and tilled only once often result in
good Scots pine regeneration [55].

Scots pine does not regenerate on dry sites occupied by Norway spruce
due to excessive humus buildup and shading. Such sites can be made more
conducive to Scots pine regeneration by prescribed burning. The humus
layer is directly reduced by fire. In succeeding years, it continues to
decrease in thickness, probably due to decreased root mass. Prescribed
burning improves many external growth factors needed for Scots pine
establishment, including nutrition, moisture availability, and soil
temperature [55].

Prescribed burning has been used in site preparation for the sowing of
Scots pine seeds in Norway and Finland [3,48]. Performance of Scots
pine approximately 10 years after planting was best on burned sites when
compared to performance on sites that were unburned but had slash
removed, or sites that were unburned and retained slash [55]. Rhizina
undulata root rot has been associated with postfire plantations of
Scots pine. As a result, prescribed burning for site preparation has
been discontinued in Finland and Sweden [1,54,55]. It is possible that
the appearance of Rhizina is associated with prescribed fires that are
too low in intensity [55]. However, the rarity of appropriate fire
weather for prescribed burning, and the labor-intensive expense of
prescribed burning have also contributed to the reduction in prescribed
burning in Scandinavia [3].

More info for the term: wildfire

In Sweden, establishment of Scots pine seedlings at high elevations
increased after fire [15]. Total pine pollen increased after fires in
Swedish core samples dated from 1,430 years BP [4]. A survey of a
burned stand of mature Scots pine in northern China showed numerous
seedlings, but no saplings [50].

Following the 1974 wildfire in Scotland, Scots pine reproduction was
densest on plots with heather. Very few seedlings occurred on sites
where sapling stands had been killed by fire. Regeneration was 2,500
seedlings per hectare at postfire year 6. By postfire year 12, some
seedlings had overtopped the competing vegetation. Postfire mortality
of burned trees was high. By postfire year 6, 45 percent of trees
greater than 2.5 inches dbh was died. Much of the postfire mortality
was attributed to pine shoot beetle (Myelophilus piniperda) attacks on
fire-damaged trees [46,60].

Scots pine may regenerate from seeds released from cones of burned
trees [60] as well as from seed from off-site parent trees. Twenty-four
years after a wildfire in Sweden, numerous Scots pine seedlings
occurred on burned sites, concentrated around surviving trees and near
the edges of the burned areas [52].

More info for the terms: resistance, wildfire

Young Scots pine trees are easily killed by fire due to their thin bark
and shallow roots. Based on the ability to recover after defoliation,
the fire resistance of 8-year-old Scots pine trees is rated as low
[36]. The heat tolerance of 1-year-old Scots pine seedlings is low
compared to a number of other conifers, including eastern white pine
[24]. Mature trees are better able to withstand fire; old trees in
Muddus National Park, Sweden, have numerous fire scars, showing that
they have survived repeated fires (intensity unreported). However,
severe fire will kill even mature trees [52].

A 1974 surface and crown wildfire in Scotland killed 74 percent of all
Scots pine burned. All Scots pine less than 2 inches (5 cm) dbh were
killed outright. Trees greater then 15.2 inches (38 cm) in diameter did
not have immediate mortality, however [60].

Scots pine seeds are moderately resistant to heat damage, and have a
good chance of surviving fire when buried. Seed germination is
good even at depths of up to 4.6 inches (10 cm) [52].

Scots pine bark is more resistant to heat than that of Norway
spruce, sugar maple, or white ash (Fraxinus americana) [14].

More info for the terms: fire cycle, fire interval, fuel, litter, mean fire interval, taiga

Scots pine forests in Sweden are rated as fire-prone and appear to
require repeated fire for their maintenance [15]. In general, pine
forests in Europe (particularly Scots pine forests) which were always
fire-prone have become even more flammable with the advent of fire
exclusion and the discontinuance of the practice of litter collection
for use as animal bedding material, fuel, etc. [26].

In Sweden, Scots pine dominates forests that have burned with a mean
fire interval of 46 years from approximately 1,100 A.D. to the present.
In some areas, the mean fire interval is as short as 30 years, although
the impact of fire has been greatly reduced in the last 100 years with
fire suppression [59]. A fire return interval ranging from 26 to 146
years was calculated for Scots pine/heather forests in eastern Finland
[48]. In the taiga of northern China, the fire cycle for Scots pine
forests was estimated at 130 years [50].

The number of years between fires decreased in areas where Scots pine
basal area increased in Muddus National Park, Sweden. In this area,
Scots pine often predominates at the lower elevations where fire is
more common and is replaced by Norway spruce at the higher elevations
where fire is less frequent [15].

Facultative Seral Species

Scots pine is intolerant of shade [42]. High mortality rates occur for
Scots pine growing under canopy. Few trees survive more than 50 years
under suppression; most do not survive even 7 years of shade [44,47].
Scots pine is not very responsive to release from suppression; trees
under 20 years old show a modest response [44,47]. Scots pine stands
are usually even-aged, or are uneven-aged with distinct age classes. In
Scandinavia, 50 to 70 percent of the trees in a stand commonly belong to
one age class, with the rest of the trees in the neighboring age classes
[22].

Scots pine usually regenerates in gaps (forming even-aged clumps) or
after stand-replacing disturbances [44,47,50]. In Sweden, most Scots
pine dominated-forests are maintained by fire. In the absence of fire,
Scots pine is usually replaced by Norway spruce (Picea abies). On some
sites, however, uneven-aged Scots pine stands are self maintaining in
the absence of fire. Regeneration peaks on these sites occurred at long
intervals and appear to be more related to favorable climatic conditions
than to any disturbances. The ability of Scots pine to reproduce
without disturbance is attributed to the thin humus and litter layers of
these poor sites [44].

The percentage of pine pollen increased after disturbances in soil core
samples dated from 1,430 years BP to present, in an area where Scots
pine is usually present [4].

More info for the terms: density, fern

Scots pine reproduces by seed. Sexual maturity can be reached as early
as 5 to 8 years of age; the usual range is from 10 to 15 years of age.
Scots pine continues to produce viable seed for up to 200 years. Good
seed crops are produced every 3 to 6 years, with light crops in
intervening years. Seed cones require alternating wet and dry weather
to open; seeds can be retained until early spring. Seed dispersal
distances range from 164 to 328 feet (50-100 m) from the parent, though
the maximum distance is greater than 0.6 mile (1 km) [42]. Seed quality,
germination, and establishment decrease with distance from the parent
plant [52].

Scots pine seedling establishment occurs on bare mineral soil. In
England, however, where Scots pine is invading heather (Calluna
vulgaris)-bracken fern (Pteridium aquilinum) heaths, Scots pine
seedlings were found even in dense stands of bracken fern; the limiting
factor on these sites appears to be proximity to seed source, rather
than density of ground vegetation [33].

Moisture stress, in the form of repeated cycles of wetting and drying,
has a pronounced negative effect on Scots pine seed germination [40].
Seedlings establish best with adequate moisture and some shade [42].
Survival is best when seedlings are planted on microsites close to the
tops of hills, and lowest in overly moist depressions [19].

There is no naturally occurring vegetative reproduction [42].

Scots pine pollen cones open from late May to early June. Pollination
occurs in early summer and is followed by fertilization 12 months later.
Seeds mature and cones ripen from September to October. Seed dispersal
occurs from December to March [27,42].

Common in the UK

Scots pine is not a threatened species but for centuries it has been cleared from much of its British range. Today, trees are being allowed to self-set and grow over much of the area where they occurred before the great clearances of the 17th century.

There are several wood boring, root feeding, foliage feeding, and twig boring insects that attack this tree. The most common pest are cyclaneusma needle cast, western gall rust, Lophodermium needle cast, tip moth, sawflies, pine needle scales and giant conifer aphid.

More info for the term: root collar

Scots pine is usually managed with a shelterwood or uniform compartment
system. In the Northeast and the Great Lakes states, reproduction is
abundant on sandy sites [32].

Scots pine requires high light intensities for good growth, but has
modest nutritional demands [55]. Certain ground vegetation types are
used as site quality indicators for Scots pine in Europe [7,35].
Scots pine performance varies greatly with site and seed source
[12,39,42]. Yields for most species in Scots pine stands in Germany
were improved when shade-tolerant species (Norway spruce and European
beech [Fagus sylvatica]) were grown in the understory. Scots pine
yields, however, were slightly decreased under those conditions [2].
Scots pine growth rates decreased with decreasing acidity in greenhouse
tests; optimum seedling growth is on acidic soils [8].

Scots pine has more branches per whorl than red pine (Pinus resinosa)
or eastern white pine (P. strobus), and is thus weaker at the nodes and
subject to wind damage [42].

Scots pine is intermediate in tolerance to foliar sprays of sodium
chloride [49].

Insects and Disease: Damaging insect species on Scots pine include
pine root collar weevil, pine root tip weevil, European pine sawfly, and
others. Scleroderris canker has become a serious problem in Scots pine
plantations in many areas. Other diseases include Lophodermum
needlecast, brown spot needle disease, and western gall rust [42,43].

There are currently no conservation projects for Scots pine.

Scots pine has several intergrading cultivars, differing chiefly in leaf color and growth form. Most have ready use as Christmas trees, although leaves of some cultivars turn yellow-green in winter. Seedlings are available at most commercial conifer nurseries. Seed origin is extremely important in obtaining quality trees for a given sub-region. Consult the state extension forester for information from provenance testing to determine the best seed source for your planting.

Weed control is recommended in areas where the tree is grown for shade or Christmas tree plantings. It is also good to shape the tree for the form that you would like to have at time of harvest.

More info for the term: tree

Scots pine is a highly preferred Christmas tree, accounting for 30
percent of all trees planted for that purpose [42]. As a Christmas tree
crop, it can be highly profitable in agroforestry systems which combine
the production of row crops with tree plantations [30]. Scots pine is
widely planted as an ornamental, and for windbreaks in the central Great
Plains [12,38].

Scots pine is used to monitor the effect of air pollution on plants [13].

More info for the term: cover

Scots pine is planted for erosion control [42]. It is used to reforest
coal mine spoils. Such plantations are valued chiefly for Christmas
tree production, providing screening and wildlife food and cover, and
asthetics [5,21,56]. In Europe, it is planted to reforest burned sites
[54].

The pine grosbeak feeds on the terminal and lateral buds of Scots pine.
Porcupines consume the bark, and girdle small trees. White-tailed deer
will browse Scots pine [10]. Moose browse it in Scandinavia and Russia
[25,34].

Scots Pine prefers full sun, moist to dry conditions that are well-drained, and an acidic sandy soil, although it also adapts to other kinds of soil. Young trees usually grow fairly rapidly, while the growth of older trees is slower. Because of disease, insect pests, and climatic factors, Scots Pine can be short-lived, but at favorable sites longevity is typically 150-300 years.

When compared to other ornamental species, Scots pine is low in
preference for white-tailed deer [10].

Scots pine is used for pulpwood and sawlogs [42].
