How can I identify edible berries/fruit in the wide and avoid the poisonous varieties? Is there a general guideline that can be followed or is each plant specific?
I'm curious how one could get/make some glue when in the wilderness. How did the Native Americans do it?
I know I could just carry a bottle, but scavenging is much more fun. What is a good source of vitamin C in the wild? Have spruce needles really got enough?
