Nature and biodiversity are meant to be varied – not just a monoculture (of one species of plant or animal). All creatures depend on others (plant and animal) for their survival. In terms of Nature, nothing is considered a ‘good’ (or a bad) one. Everything is part of the food chain.
A central principle of ecology is that each living organism has an ongoing and continual relationship with every other element that makes up its environment.
However, if you want a garden full of butterflies, you must start with a space that is butterfly-friendly. There are great ideas for reducing the major negative impacts that can affect your butterflies and host plants in our  Online Course.
