I fully agree that a garden overtaken by brambles isn't a nice thing. But it's also not true that scrubland in general is some kind of death to nature.

That means they're good habitats for many species of bird, and also that they're nature's nurseries for woodland, as young trees are protected from passing deer and other animals that would otherwise eat them.
