British Columbia is covered in highlands; its eastern boundary is the Rocky Mountains. Agricultural production in British Columbia supplied the gold rush industry, mining and logging industries. Agricultural producers relied on these local markets, following the economic boom and bust of each enterprise respectively. The British Columbia Fruit-Growers' Association was established in 1889 to foster an export market of this commodity. The Canada Agriculture Museum preserves Canadian agricultural history. In 2015, there are approximately 20,000 farms in B.C. that are involved in agricultural activity, such as dairy, livestock, fruit and vegetable farming.
