Florida’s orange groves are still shrinking as the state battles the tree-killing citrus greening disease and farmers sell their land, the annual Department of Agriculture census showed on Thursday.

The number of commercial orange trees and total acreage devoted to orange groves have steadily shrunk over the last five years in Florida, which accounts for two-thirds of U.S. citrus fruit production.

The state has 63.78 million commercial orange trees, down about 1.9 percent from 2009, the USDA said.
