Here is a list of scavengable places that can be found in NeoScavenger, each with it's full in-game fluff text.
Wild Places[]
Wild places are a great source of food. When scavenging, it is possible to find berries and mushrooms, though it is important to note that about half are poisonous. In these places, the Botany skill will increase your loot about the same as the strong skill. Using a squirrel snare while scavenging will guarantee 1-2 squirrels.
Open Field[]
Stretch of Forest[]
Forest Shack[]
Ruins[]
Ruins should not be your first choice for scavenging. While they provide similar, though slightly less due to frequent injury, loot to abandoned buildings, the safety is significantly lower, especially when using traits like strong and the crowbar. It is easy to get several scratches and bruises.
Crumbling Apartment Building[]
Destroyed Office Building[]
The Black Swamp[]

Abandoned Buildings[]
Abandoned buildings are the best place to get loot to sell. It is possible to get sleeping bags, clothing, medicine, weapons, backpacks, vehicles, and more here. While there is food to be found here, its mostly foods that are valuable, but not that practical, such as Whiskey, Snack Cakes, and Saltine Crackers.
