You can use climbers to great effect if you want to attract wildlife to an urban garden. Birds covet fruit or nectar from the flowers of different climbers. Several have leaves which caterpillars enjoy. The caterpillars in turn attract more birds. Thick climbers and scramblers provide good nesting sites for birds. The screening and draping qualities of climbers make them essential features of a wild and secluded garden. Plant them close together so that they intertwine, or train them up trees. (Keep them under control if they climb your favourite trees, however.) Bring down old branches or unsightly alien trees by letting a robust climber run rampant over them.
