FRasin

Frasin, in the Romanian language, refers to ash trees, belonging to the genus Fraxinus in the olive family Oleaceae. Ash trees are deciduous and commonly reach substantial size, with a broad or oval crown. They typically have opposite, pinnate leaves with 5–9 leaflets, though leaf form can vary among species. Flowers are generally inconspicuous, and the fruit is a winged samara that is dispersed by wind. In forests and urban landscapes across the Northern Hemisphere, frasin species often play a key ecological and aesthetic role.

The genus Fraxinus contains numerous species, including notable ones such as Fraxinus excelsior (European ash), Fraxinus americana (white ash), and Fraxinus pennsylvanica (green ash). European ash is common in European woodlands and hedgerows, while white and green ashes are widespread in North America. Ash species typically prefer temperate climates and well-drained soils, and many are valued as canopy trees in forests and streetscapes.

Ecology and threats: Ash populations face significant threats from introduced pests and diseases. The emerald ash borer (Agrilus planipennis) has caused extensive mortality in North America, while Hymenoscyphus fraxineus has led to ash dieback in parts of Europe. Urban stress, drought, and climate change can exacerbate susceptibility and decline.

Uses: Ash wood is prized for its strength, elasticity, and workability. It is used in furniture, flooring, cabinetry, tool handles, sports equipment such as baseball bats, and oars. Because of their timber value and ecological role, frasin trees are often targets of conservation and careful urban management.
