Poplar species

Poplars are generally trees (although sometimes bushes) that naturally grow along riverbanks. Their natural habitat is in the northern hemisphere, and botanists have identified 30 different species, which can be divided into 5 principal groups.
The best known species in Europe are the Black Poplar, the White Poplar and the Common Aspen. The best-known species in America are the Eastern Cottonwood and the Black Cottonwood, both of which can also be found in Asia and Africa.
Since some species are able to reproduce with others (hybridisation), at least 20 further different types of poplar which mix the traits of 2 or sometimes even 3 basic species. This characteristic, along with the trees´ ability to regenerate themselves indefinitely from stump or root shoots, means that the planting of poplars is both efficient and effective.

Ecological characteristics

Poplars love light and water. They reproduce easily from seed and different species can be crossed. They can also be grown from stump, root and adventitious shoots, which enables the life of an individual specimen to be prolonged indefinitely, constituting that which is technically known as a clone.
The trees grow rapidly as long as they are planted in good soil and they provide major environmental benefits to society, such as the absorption of CO2 which helps combat climate change. They also help prevent the erosion of riverbanks and provide protection for nearby crops. Furthermore, they are able to survive in polluted soil.
Together, all these characteristics make them one of the primary woody species colonising barren regions next to the riverside, where other species have trouble surviving.
Finally, they are often found close to cities and towns located on plains.

Poplar wood

The main characteristic of poplar wood is its lightness and low density in comparison with that of other leafy or conifer trees. There are very few species that weigh less while offering the same level of resistance and hardiness.
The sapwood is white while the heartwood is darker and has a pleasant smell. Since the trees grow very quickly, it is easy to distinguish their growth rings and calculate their age. The texture of the wood is fine and the grain regular, giving it an attractive,clean appearance.
Hardness, however, is not one of its qualities, and the wood is easily marked if it is struck or knocked by a hard object.
Because it grows so quickly, it accumulates growing tension that is released when the tree is cut. This usually gives rise to cracks, thus rendering it unsuitable for peeling. This is a major problem because it is the peeling process that makes the manufacturing of plywood board possible. This defect has been partly solved by selecting only the best varieties that are well adapted to the soil in which they are grown, and by ensuring proper cultivation practices.

Basic tree for forestry research

Its qualities make it an ideal model and a useful tool for forestry research. In this sense, it is comparable with other model species, such as the Drosophila (vinegar fly) in biology and the Arabidopsis (rockcress) in agriculture, the first species whose genetic map was identified. Today, the genetic map of the poplar is also known, thus enabling enormous progress to be made in addressing some of the major problems facing humanity, such as the fight against climate change and the distribution of natural forests.
“Knowledge, not wood, will solve humanity´s need for this raw material in the 21st century.”

The wood of the 21st century

Until the 20th century, the majority of mankind’s wood supply came from the felling of trees growing in natural or semi-natural conditions. The FAO estimates that wood consumption will have risen from 1,600 million m3 in 1992, to 2,420 million m3 by 2020. To meet this demand without destroying natural forests, mankind will need to grow wood in plantations in accordance with the principles of environmentally sustainable, social and economic management.
Just as the domestication of agricultural plants has enabled us to produce food safely and efficiently within a small area, the domestication of trees and their cultivation for wood production will enable us to guarantee a steady supply of this raw material.
Due to its qualities, in the 21st century poplar wood will prove vital for the future of mankind on Earth.
In accordance with the thinking of Patrick Moore, founder of Greenpeace, we at Garnica believe that the correct forestry policy is to plant two trees for every one that is cut down.

Composition
Sample Image

 

Our plywood is produced using POPLAR veneers throughout, crosswise glued with urea-based resins (UF- IF20) or with urea-melamine based glues (MUF- A100). Outer faces are usually long grain running in the sense of the length (LONG GRAIN panels). The production process in checked in all its stages.

The exclusive use of POPLAR gives a white colour and the panel is flexible, light and strong.

Classification according to outer faces

Poplar plywood is usually classified according to the external faces.
Our poplar plywood can be:
AB/BB - B/BB - BB/BB - C/C
