Well, as I put on a tin helmet, I think walls and fences covered in ivy and Hydrangea x petiolaris
are wildlife havens. They can accommodate several neighbouring nests for different species at different nesting heights, provide night roosts all year round, offer nectar early in the season and shelter countless invertebrates. Butterflies, moths and spiders particularly.
(English Heritage & The National Trust funded research showed that unless the mortar is already degraded the ivy prevents fluctuations from baking sun to rapid drops in night temperatures, wind and rain erosion and air pollutiion. Ivy is even shown to be a protecting factor in towns and cities where car exhaust emissions are high).
