Was involved with a study on dairy cattle in the area where the elk were eventually placed. Was in 1977. Dairy cattle expressed deficiency symptoms consistent with copper deficiency. UC Davis found no copper deficiencies in the cattle expressing the symptoms. Leslie salt rep said that copper supplemented salt would work and it did. Leslie rep then said that molybdenum toxicity can express as copper deficiency. SCS did soil studies that confirmed high molybdenum levels and found historical records of an active molybdenum mine in that area of the Point Reyes National Seashore. Since the Tule Elk were introduced into the area where the cattle expressed the copper deficiency, and they may well have also suffered from molybdenum toxicity. The Tule Elk may have resolved the pseudo copper deficiency by utilizing the salt licks that Leslie salt supplied to the local dairy farms. Rbudding (talk) 23:14, 8 November 2019 (UTC)
