Physical Characteristics
The Cashew tree can grow up to a maximum height of 12-14 meters and has a spreading canopy. The leaves are leathery, elliptical, and dark green in color, while the flowers are small and pink. The tree produces a fruit that is kidney-shaped and contains a single seed, which is the cashew nut. The nut is attached to a fleshy, apple-like structure called the cashew apple, which is edible but not as widely consumed as the nut.
Ecological Role
The Cashew tree plays an important ecological role in India. It is a hardy species that can grow in a wide range of soil types and is resistant to drought, making it an ideal species for afforestation in arid and semi-arid regions. The tree also helps to prevent soil erosion and promotes the growth of other plants by providing shade and shelter.
Importance to Birds, Animals, and Insects
The Cashew tree is an important source of food for birds, animals, and insects. The cashew apple is eaten by a variety of animals, including monkeys and squirrels, while the nuts are a favorite of birds such as parrots and crows. The tree also provides a habitat for insects such as bees, which are important for pollination.
