AMARILLO, Texas (AP) — Texas ranchers are facing at least $21 million in agricultural damages from wildfires that blackened more than 750 square miles in the Texas Panhandle.

Economist Steve Amosson tells the San Antonio Express-News (http://bit.ly/2mN9ZcX ) that damages last week included $6.1 million in lost pasture land, $6.1 million in lost or damaged fencing, $3.8 million in lost buildings, $4 million in livestock deaths and $1 million for emergency hay and feed.

Amosson says long term effects can depend on how the remaining 13,000 to 14,000 cattle will be fed with reduced grazing land.

The Texas Animal Health Commission determined Wednesday that 2,500 head of cattle and 1,900 swine were lost to the fires in Texas.

At least six people died in the wildfires.

Texas Gov. Greg Abbott has declared a state of emergency in six counties.
