Silver birch also demands slightly more summer warmth than does Downy birch, which is significant in the cooler parts of Europe.

The most common tree species are the native Norway spruce, Scots pine and Downy birch.

Betula pubescens (Downy birch)

The downy birch aphid has a pale green body, lightly dusted with bluish wax particles, membranous wings and long legs.

Around this an outer circle of Downy Birch trees has been planted by the parks department in 2010 to supply the need for further ex-service dedicated plaques.

The bark of the downy birch is a dull greyish white, whereas the silver birch has striking white, papery bark with black fissures.

Specimens of the subarctic populations are usually small and very contorted, and are often distinguished as "arctic" downy birch, Betula pubescens subsp.

Typical boreal species are Norway spruce, pine, downy birch, grey alder, aspen, rowan, wood anemone and Viola riviniana.

Withybed Wood is home to a variety of tree species including Downy Birch, English Oak and White Poplar.

The predominant tree species in the wood is Corsican pine, interspersed with beech, wild cherry, rowan, ash, silver birch, downy birch and sycamore.

The lower part of this zone also has conifers, but the tree line in Norway is mostly formed by mountain birch, a subspecies of downy birch (ssp.

Euceraphis punctipennis, the downy birch aphid or European birch aphid, is a species of aphid in the order Hemiptera.

The downy birch aphid feeds on sap and exudes copious amounts of honeydew which coats the leaves on which it feeds.

Species of tree and shrub include Ash, Downy Birch, Hazel, Hawthorn, Yew and Rowan.

Downy birch can be distinguished from silver birch in having smooth, downy shoots, which are hairless and warty in silver birch.

They are also distinguished cytologically, silver birch being diploid (with two sets of chromosomes), whereas downy birch is tetraploid (four sets of chromosomes).

It doesn't seem to have the disease problems of white birch, so I would like to plant more, but can't find them.

Betula pubescens (Downy birch)

In Europe, the closely related downy birch (Betula pubescens) has its own species of aphid, Euceraphis punctipennis.

Here, Willow (Salix glauca) and Birch (Betula pubescens) trees grow up to a height of several meters.

As the peat has become drier, areas have been taken over by purple moor grass Molinia caerulea and by downy birch Betula pubescens.

The scrub community of Allt Volagir, also in South Uist and mentioned in the same paper, is somewhat similar, but Betula pubescens is absent.

At Langley Moor there is an area of woodland which is dominated by downy birch, Betula pubescens, with some sessile oak, Quercus petraea.

The larvae feed on Alnus, Betula pendula, Betula pubescens, Carpinus betulus and Corylus avellana.

Silver Birch (Betula pendula) / Downy Birch (Betula pubescens)

Other characteristic species present apart from the three by which the community is named are Populus tremula, Betula pubescens, Sorbus aucuparia, Salix auritalcinerea and Epilobium montanum.

The larvae feed on various plants, including Vicia, Rumex, Scirpus, Calluna vulgaris, Betula pubescens, Stachys palustris and Vaccinium uliginosum.

It is also a fairly common Icelandic name given to girls meaning birch, specifically the most common native tree of Iceland, Betula pubescens tortuosa (Arctic Downy Birch).

These woods are also home to some deciduous trees such as rowan, silver and downy birches (Betula pendula and Betula pubescens) and willows (Salix spec.)

Foremost among them were the birches, Betula pubescens and Betula pendula, accompanied by Sorbus aucuparia and Quaking Aspen, Populus tremula.

Although the scientific name populetorum might suggest the larvae feed on Poplar, they only feed on the leaves of Betula species, including Betula pendula and Betula pubescens.

There are also areas of grassland and a secondary woodland of downy birch, Betula pubescens, with a groundcover of rush, bog mosses and purple moor-grass, Molinia caerulea.

In the British Isles, there is some difference between the environments of Betula pendula and Betula pubescens, and some hybridization, though both are "opportunists in steady-state woodland systems".

NVC community W11 (Quercus petraea - Betula pubescens - Oxalis acetosella woodland) is one of the woodland communities in the British National Vegetation Classification system.

The principal species are sessile oak, Quercus petraea, birch, Betula pubescens and hazel, Corylus avellana, with alder, Alnus glutinosa, locally dominant along the watercourses and at springlines.

The larvae feed on Alnus, Betula lutea, Betula pubescens, Carpinus betulus, Crataegus laevigata, Malus domestica, Sorbus aucuparia and Tilia species.

The larvae feed on Betula ermani, Betula grossa, Betula humilis, Betula nana, Betula obscura, Betula pendula and Betula pubescens.

At still lower altitude is the adjacent montane birch zone with small (2-5 m) mountain downy birch (Betula pubescens) above the conifer tree line; some stunted spruce and pine, and many lakes and bogs.

In addition to the pine and the spruce, Betula pendula, Betula pubescens, Populus tremula, and Alnus glutinosa (the latter along some creeks) are the taller tree species encountered in the national park.

The hill slopes are wooded with downy birch, Betula pubescens, mixed with ash, Fraxinus excelsior, and rowan, Sorbus aucuparia, with an understorey of hazel, Corylus avellana, a species not usually associated with birch.
