I reseeded my lawn with clover and saw a huge increase in all kinds of lightening bugs, bees, etc. Alos rabbits which surprised me (I'm in the middle of a dense urban area... there is a park nearby, though)

Nice! I forgot to mention that I also added microclover the the mix last fall. The bees love the little clover flowers.

lawn grass massively harms the environment, as do topiaries
