While you are out hiking, sketch or take a picture of 3 things that you think might be edible.
In a journal or through your sketch make sure to note the following:
Is it an animal or a plant?
Does it have berries or nuts?
Identify it’s different parts: leaves, stem, roots, flowers, berries
What do the leaves look like? (Hairy, smooth, lobed, jagged)
Are the leaves opposite or alternate
How does it smell?
What makes you think they are edible?
See if you can identify the plant with this Plant ID link, then use this Edible Plants link to see if it is something you can eat. If you do not find it on the list, look further to see why it is not on the list.
