Are you building or renovating? Then think about including shelter for local fauna.
Find out about species that could nest around your home: which would you like to house? Then, make the necessary arrangements: bore holes in a thick wall and leave small spaces (for bees), make holes in building blocks (for bats), provide access to a granary (for birds of prey and bats), set up nesting boxes on the roof and on balconies, etc.
There is a lot you can do. Having the most diversi?ed garden possible will make it easy for your guests to eat. Never use chemical products (pesticides, fertilizers, paints, detergents, etc.)
