Boulder County, Colorado

Ferberite. which has monochnic tabular crystals, sometimes massive, resembles wolframite, and occurs in Spam and in Boulder County, Colorado. Superb crystals of Ferberite in association with apatite and arseuopyrite crystals occur at Panasqueira, Portugal. 

One model for coexistence between GE and non-GE crops is the program established for publicly owned land in Boulder County, Colorado (Byrne and Fromherz, 2003). The county leases about 4,000 acres of cropland to farmers, some of whom have chosen to grown insect resistant or herbicide tolerant GE corn. An advisory committee of farmers, scientists, and concerned citizens developed a set of protocols to minimize cross-pollination to nearby non-GE corn fields. The protocols include grower notification to the county of their planting intentions, communication among neighboring farmers to work out an acceptable coexistence plan, and establishment of a 150-foot buffer zone between fields to minimize cross-pollination.
