Very important video! Bees seek out rotten logs to make hives in. This is because the mushroom mycelium growing in these logs gives medicine to the bees immune systems! (They drink the liquid from the mycelium!!!)
Please put more dead wood and logs in your gardens and land. For the pollinators and mycelium (mushrooms) and other lifeforms that benefit from it. The more diverse an ecosystem (your garden/land) is the healthier it is!
