A large number of trees in California have begun turning black in recent days.
The state’s Department of Forestry and Fire Protection confirmed the state’s first tree death since the outbreak began on Monday.
State officials say the tree deaths have not been linked to the virus, which has since been eradicated in the state.
The department has ordered all bonsaii tree licenses to be suspended for one week.
Officials also said that some of the trees were not infected with the virus and were just in their prime.
Officials say they have ordered an additional 100,000 trees to be removed and that they expect to have an official count of the number of infected trees by Wednesday afternoon.
The disease is spreading fast and has already affected nearly every state in the country.
Officials in California say they expect at least 1,200 additional deaths by the end of the week.
