Botanical Identification
Ecology
The ecology of Salix alba is characterized by its preference for riparian environments, specifically inhabiting places near rivers and other moisture-rich zones. This species exhibits a broad altitudinal distribution, spanning from sea level up to a maximum elevation of 3100 m AMSL. Across its natural range, the plant maintains an average elevation of approximately 2450 m AMSL, demonstrating a significant capacity to adapt to diverse vertical gradients within its hydrological habitats.
- Elevational range max:
- 3100 m AMSL
- Elevational range mean:
- 2450 m AMSL
- Elevational range min:
- 0 m AMSL
- Habitat :
- inhabited places, rivers
Life history
The life history of Salix alba is characterized by its existence as a perennial species, allowing it to establish long-term presence within its riparian habitats. As a phanerophyte, the plant maintains its photosynthetic organs on elevated woody structures, specifically categorized under the phanerophyte life form classifications which indicate its stature as a tree. Its seasonal rhythm is defined by its deciduous nature, meaning it sheds its foliage annually in response to environmental cues, typically entering a period of dormancy during colder months. This combination of a perennial lifecycle, a phanerophyte life form, and deciduous phenology enables the species to thrive and regenerate across multiple growing seasons.
- Deciduousness :
- deciduous
- Life form :
- phanerophyte
- Lifecycle :
- perennial
Morphology
The morphology of Salix alba is characterized by its growth form as a woody tree, which functions as a self-supporting structure rather than a climber or vine. As an independent organism, it does not exhibit parasitic or epiphytic behaviors, maintaining a terrestrial habit. The plant reaches significant dimensions, with its height typically ranging from a minimum of 5 meters to a maximum of 30 meters, maintaining an average plant height of approximately 19.04 meters.

Physiology
The physiology of Salix alba is characterized by a C3 photosynthetic pathway, operating as a non-carnivorous organism that does not possess the ability to fix nitrogen. The plant's leaf morphology exhibits significant variation, with leaf lengths ranging from a minimum of 5 cm to a maximum of 12 cm, maintaining a mean length of 8.5 cm. The leaf width is similarly variable, spanning from a minimum of 0.5 cm to a maximum of 3 cm, with a mean width of 2 cm, resulting in a mean leaf size of 7.82125 cm². Furthermore, the plant demonstrates a mean Specific Leaf Area (SLA) of 118.94 cm²/g, reflecting its leaf mass distribution per unit area. Supporting its structural integrity, the stem maintains a mean stem specific density (SSD) of 385 mg/cm³.

Reproduction
The reproduction of Salix alba is characterized by a sexual process that is strictly dioecious, meaning individual plants are either male or female, and self-fertilization is noted as absent. The flowering period typically commences in April and concludes in May. During this phase, the plant utilizes a biotic pollination syndrome, specifically relying on insects for the transfer of pollen. Following successful pollination, the plant develops fruit in the form of a capsule. These capsules are dehiscent, meaning they split open at maturity to release the seeds. The seeds are remarkably lightweight, with a consistent mean, minimum, and maximum mass of 0.00012 g. For dispersal, the species employs an anemochorous syndrome, utilizing the wind to transport its tiny seeds to new locations. Notably, asexual reproduction is absent in this species.
