Are these not a fire risk? They look conceptually similar to brush fences, which are allegedly illegal near me due to fire risk.
They certainly can be in certain climates and areas of wildfire risk. In those circumstances a good biochar session might be advisable as a way to put this type of woody debris towards supporting wildlife, since healthier soils will grow healthier plants which will support the fauna you're aiming to help.
All things green, outdoors, and nature-y. Whether it's animals in their natural habitat, hiking trails and mountains, or planting a little garden for yourself (and everything in between), you can talk about it here.
