Many crops Hangkerimians use are known in OTL, like maize, potato and yucca.
Maize was first grown in OTL Mexico 8000 years ago in small communities, and reached Hangkerim territory about 6000 BP. When the Hangke confederation was formed, maize was cultivated by all mayor nations.
Potato was mainly used by highland cultures, among them the Moscha and the Kogila. Moscha had an important repertory of roots for consumption.
Yucca and mandioc were mainly used by lowland cultures like Calamy and Hembica. All these crops are extensively used now a days
Precolombine hangkerimians had developed ways of using parts of feeding plants for extracting their fibers for textile industry, but there was some plants specially used for their fibers, the main are cotton and agave.
In construction guadua, a bamboo species, was grown. Hard wood trees ware used as well. Guadua has a growing popularity in the last years after is a renovable resource.
Among all the plants with allucinating effects, coca and tobacco has been the most important. Coca was known for several tousend years but begun to be grown circa 4000 BP. Coca chewing is the most important use, coca tea use was limited in Hangkerim and refined cocaine was only used by shamans.
Tobaco was brought by Semtalika people during the invasion.
Unlike OTL America, in Zera Timeline, many animals were domestic by Native Americans.
Hangkerimians had imported Andean llama by 3000 BP, and were mainly used by highland people like Moscha. Llamas where used as burden animal as well as for their wholl, milk and meet.
The Appalachian llama that survived in ZTL were tamed by 5000 BP and a lowland variety was brought by Semtalika people 2500 BP. This kind of Llama was mainly used as burden animal and for its meet. Semtalika also brought a few number of horses but they where never used by Hangkerimians and eventually became wild or died in cautivity. Horses were never riden by any Native American culture before Europeans came.
Besides llama and horses, Hangkerimians had domesticated or imported many mammals, rodents mainly, like guinea pigs and capybara. Another kind of domesticated animals were tapir.
On birds, only turkeys were used after Semtalika brought them. Some ducks where also kept and used but they where not grown by people and remained wild.
Other kind of animals where farmed for meet, like iguana and some species of fish. Now a days, those farmed iguanas and fish are counted as domestic, while some other species of fish and reptiles (like cayman) are being farmed.
Hangkerimians had no companying animals before the Semtalika invasion, when dogs where brought.
Between the main animals Europeans brought to America are the Eurasian horse, kine, shep, hog and cats.
