Hazel trees are deciduous, so they lose their leaves in winter. Hazel trees are wind pollinated but some bees will visit the\u00a0catkins<\/a>\u00a0for pollen.<\/p>\n\n\n\n

Flowers<\/h2>\n\n\n\n

Hazel is monoecious, meaning that both male and female flowers are found on the same tree, although hazel flowers must be pollinated by pollen from other hazel trees. The yellow male catkins<\/a> appear before the leaves and hang in clusters from mid-February. And male flowers release pollen before falling off. Female flowers are tiny and red, and appear as wispy red petals protruding from a small bud, typically on the branch just above the catkin.<\/p>\n\n\n\n

Fruits<\/h2>\n\n\n\n

Once pollinated by wind, the female flowers develop into oval fruits which hang in groups of one to four. They mature into a nut with a woody shell surrounded by a cup of leafy bracts (modified leaves).<\/p>\n\n\n\n

Hazel trees are a valuable resource for wildlife, providing food for insects, birds, squirrels and dormice, as well as a habitat for butterflies. Hazel trees are also used by birds to shelter in. In woodland, hazel trees are coppiced to help create a better habitat for wildlife, mimicking the actions of beavers. The result is a multi-stemmed shrub, which provides a place for dormice to nest and also lets more light into the woodland. This allows more flowers to grow on the ground, which is good for pollinators.<\/figcaption><\/figure>\n\n\n\n
