Rhododendron (Rhododendron ponticum)

Rhododendron originated in Armenia and eastern Turkey and was first introduced to the UK as seed in the 1760s and became readily supplied by the nursery trade throughout the late part of the 18th Century and early part of the 19th Century. Its ability to send out suckers from any buried root material and its effective seed production mean that it has now reached invasive levels in many parts of the country.  It often shades out many of the native flora and has overtaken the growth of more native species in the oak woodlands and heathlands of Western Europe. Soil and weather conditions in the UK are also ideal for the growth of Rhododendrons.

There is no danger to the health or safety of humans or animals. Danger to biodiversity is the main problem posed, where in some areas the population of birds, earthworms and other wildlife can be massively reduced in an area invaded by Rhododendrons.

Clearance is usually the first stage in habitat regeneration. Once access has been gained the exposed stems and roots of the plant can be treated. In some cases this may involve injecting the roots with a herbicide, and in other cases complete mechanical removal of the root ball material.
