Small Atlas Of Mountain Trees (2nd part)

Welcom to the second part of our small atlas of moutain trees. I the first part we wrote about coniferous trees. In this one we talk about deciduous trees present in european moutain and the northern hemisphere.
Here the italian version of this atlas.

Index

In this atlas we present the following trees::


Beech (Fagus Sylvatica)


The most common deciduous tree in the Alpine area, the plant that colors the woods with her bright green. It can form pure or mixed forests with spruce trees, starting from an altitude of 600-700 meters even up to the tree line.

Leaves: oval, the edge almost flat or slightly wavy, medium-sized, slightly shiny.

Chioma: wide and thick oval-elliptical tending upwards. Some adult specimens can reach a height of around 20-30 meters. The trunk is tapered in young specimens, in which can be found in strains with numerous ramifications; in adult specimens it is irregular and gobboso.
Bark is light gray with biacastre patches, smooth, horizontal streaks, not particularly thick.
Fruits: the seeds are enclosed in red-brown wood casings oval, covered with prickly spines not, that remain on the plant for several seasons.



BIRCH (Betula)


It 'a typical plant of the northern hemisphere, in particular, with regard to Europe, in Scandinavia. And 'an elegant tree, with a tapered stem which can grow up to 25 meters, and is known for its great flexibility.
Often it grows in sunny areas, away from other trees of the forest.

Leaves: drop-shaped, with a length between 4 to 5 cm; the flap is notched, the matte surface and rough, from not really bright green.

Foliage: in adult specimens reaches an oval shape, not particularly thick because of the small size of the leaves. The thin twigs tend downwards in the terminal part.
Cortex: the main feature is the color white. The rind is thin, striped horizontally.
Fruits: form a small tubular spike, green and compact initially, light brown and tends to fall apart when mature.


CHESTNUT (Castanea sativa)


This tree is well known for its fruit. Growing at different latitudes, but in low mountain it is located in the area between 300 and 800 meters, in mixed forests with ash, hornbeam, walnut and hazelnut.
Form a large diameter stem which can reach up to 2 meters, with more derivations tending upwards.

Chestnut

Leaves: elongated, between 10 and 20 cm, the edge is serrated and ends with a tip; the surface is glossy and deep green at the top, clearer on the lower one.

Chioma: large and dense in adult specimens, it may tend to assume a spherical shape and irregular indicated by huge ramifications.
Bark: smooth, thick, brownish-gray, with deep vertical streaks. The stem can be screwed over time and become highly irregular.
Fruits: the chestnut grows in curls that they collect from 1 to 3, at maturity the hedgehog opens in four releasing the fruit.


MAPLE (Acer pseudoplatanus)

Pianta ad alto fusto (può raggiungere i 25-35 metri), che cresce in boschi collinari e di bassa montagna, spesso su terreni abbandonati e colonizzati da vegetazione mista, in particolare insieme al frassino.

Leaves: from the typical form in five lobes, have serrated margins and large-area (also 15x15cm), opaque, dark green above and gray below.

Coma: dense, rounded, face up.
Bark: gray-brown, it is generally smooth and furrowed by small horizontal cracks.
Fruit: the fruit is recognizable, consisting of a protected seed from a yellow-green membrane that stretches up to create a helix, which allows you to spread far from the parent plant.


ELM (Ulmus glabra)


Pianta dal fusto dritto e molto ramificato dal basso, mediamente alto (fino a 25m), si può trovare a quote variabili, dai 400 ai 1400 metri.

Elm

Leaves: oval with obvious point at the end, serrated margins, reduced size (about 5 cm), dark green on the upper surface, lighter and hairy on the bottom.

Elm

Chioma: large and irregular because of the many ramifications that depart from the bottom.
Bark: initially smooth gray-green color, with age it becomes flaky and uneven.
Seafood: the "maple keys" are gathered in groups, it is a nearly oval translucent membrane that encloses the small seed.


HORNBEAM (Ostrya carpinifolia)


Reduced plant height, is located in the medium-low altitudes in mixed woods with maple trees, oaks, pines. In the woods usually it assumes a clumping form.

Hornbeam
Hornbeam

Leaves: oval and pointed, serrated from margin, medium size.

Chioma: sparse, spherical and irregular.
Bark is brown in color, is smooth and dotted in juvenile stage and becomes wrinkled with age.
Fruits: the seeds are enclosed in green membranes (a brown maturity) of elongated oval shape, gathered in drooping clusters that remain on the branches even in advanced seasons.
