Ticks spread when there are host mammals, nearly regardless of vegetation height.

I'm with you on the dead ecosystem thing. Besides the vegetable patch, my garden is deliberately a happy self-regulated mess of grass and wild strawberries, trees and bushes, planted flowers and all sorts of plants and mushrooms. I only remove the thorns, and walk though with a scythe twice a year (one tough enough to cut the smaller saplings). It's quite rewarding to watch the birds, small mammals and amphibians that thrive there, and a delight for my young daughter. It is quite a surprise to hear that I'd have trouble doing that in the land of the free. Thank you for the insight !
