Ivy is an important plant for wildlife
English Ivy (Hedera Helix) is a valuable evergreen ecosystem. As well as providing nesting sites and shelter, it is a source of food and pollen for wildlife. Beneath its leaves insects, birds, butterflies and even small mammals, frogs and toads will shelter. Its nectar rich autumnal flowers and winter berries provide food when there is little else to feed on.
Only mature ivy, distinguished by un-lobed leaves, will flower then fruit.
Even our Portbury Wharf roe deer will dine out on ivy when the opportunity arises.
Ivy is a liana or climbing plant. People often think it is a parasite, feeding off the trees it wraps itself around, but it is not. It gains no nourishment from the tree it clings to so does not kill the trees it grows up. However it may cause some damage by its sheer weight or by shading the tree. It can also happily grow along the ground or up a wall or even stand on its own if thick enough.
Ivy flowers from September to November. Butterflies, bees, wasps, hornets and many others come to feed on the nectar-rich flowers. So popular are the flowers that in late summer you can hear a heavily flowering ivy bush, it buzzes! It buzzes to the tune of hundreds of bees flying from flower to flower.
In November queen wasps, queen bumble-bees and queen hornets come to fuel up before their winter hibernation.
The Ivy Bee and the beautiful white Swallow-tailed Moth are two species in particular which love ivy. You can read more about these species at www.wildlifetrusts.org/wildlife-explorer/invertebrates/bees-and-wasps/ivy-bee and https://butterfly-conservation.org/moths/swallow-tailed-moth respectively. The caterpillar of the Swallow-tailed Moth brilliantly imitates a twig. It takes some finding!
Many berries start forming while other flowers are only just opening. By December most of these beautifully architectural berries will have ripened to black. Once ripe these calorie rich ivy berries will feed many birds throughout the winter months lasting until April if uneaten. Indeed according to the RSPB, ivy berries contain nearly as many calories as Mars bars!
