hunting , gathering of seasonal food sources required intimate knowledge of local plants of several regions tribe used territory throughout year. annual peregrination involved moving follow seasonal emergence of tubers, fruit, seeds, nuts, insects , possibly migrating animals or birds , collecting aquatic food. knowledge of clams, mussels, & seasonal fish gathered water sources bulbs & berries along riparian or littoral shore along migration route.

people developed culture based on knowledge of surrounding habitat. culture passed along details , differences of many different ecologies. knew timing of plant emergence seasonal changes, amounts needed harvest , how collecting habits influenced plant/animal populations.

along went development of tools , techniques in stone age culture. burning clear encroaching brush , other management techniques (weeding, pruning, transplanting encourage desirable wild plants) used long before agricultural tilling/sowing/reaping/storing became primary support of permanent villages. there continual gathering of knowledge , skills passed along , added on time cultures went gathering domestication.
