Characteristics of Populus tremula
El Populus tremula tree, commonly known as aspen o aspenIs a deciduous tree Native to the mountainous and humid regions of Europe and Asia. This tree stands out for its large size and elegance, reaching heights of up to 30 meters. Its trunk is straight, with a bark that is initially greens, turning grey over time and showing cracks in older specimens.
the leaves are simple, alternate and have a long, flattened petiole that allows them to move easily in the wind, creating a characteristic visual effect that gives it its name of 'trembling'. During the fall, the leaves present a range of vibrant colors that vary from the yellow al Red, which makes them especially attractive.

Structure and morphology
Populus tremula is known for its leaf-shaped leaves. heart o oval, whose dimensions vary between 2 and 8 cm in diameter. In young trees, the leaves can reach up to 20 cm, but their shape remains different, typically being larger and more irregular. The tree's structure is ideal for forming wind chimes, which is often associated with its presence in open, bright areas.
Reproduction and life cycle
The aspen is a dioecious species, meaning it has both male and female trees. The flowers appear in comments hanging, in spring, before the leaves sprout. The flowers are pollinated mainly by the wind and produce capsules that release countless seeds in summer, which are dispersed through the air thanks to delicate cottony hairs. This dispersal method ensures that the seeds can travel long distances, where they can eventually find suitable soil to germinate.
Habitat and distribution
Populus tremula thrives in a variety of habitats, from river banks but also mixed forests, often found at altitudes ranging from 50 to 2,000 meters. In Europe, it is found in regions from northern Scandinavia to southern Spain and Turkey. Specifically in the Iberian Peninsula, it is most common in northern mountainous areas and in humid areas along rivers, such as the Ebro basin and the Sierra de Guadarrama mountain ranges.

Uses and benefits
The wood of Populus tremula is appreciated for its lightness y elasticity, making it ideal for a variety of uses, from the production of boxes y packaging until the manufacture of furniture and kitchen utensils. In addition, its bark and buds have traditionally been used in folk medicine, acting as febrifuges and antiscorbutics, as well as in treatments for hemorrhoids.

ecological characteristics
Populus tremula is considered a pioneer species in reforestation, as it establishes itself quickly in disturbed areas. This tree is resistant to frost, which allows it to survive in extreme climates. However, it is susceptible to certain diseases such as cancer, which requires regular monitoring of trees planted in urban or rural areas.

Protection and conservation status
Despite its wide distribution, the aspen has been classified in some places as Threatened speciesThis may be due to habitat loss and changes in land use. In the Iberian Peninsula, conservation plans have been implemented to protect Populus tremula populations and ensure their presence in local ecosystems.
Other related species
The gender Populus It includes several species, being the the white one of its closest relatives. Hybrids between these species, such as Populus × canescens, are also common and have been used in forestry for their rapid growth rate and timber value.
