Gov. Andrew Cuomo directed additional state emergency workers to an upstate brush fire that so far has consumed about 300 acres.

First responders were building a perimeter around the blaze that on Sunday was moving south within the mountainous Sam's Point nature preserve near Ellenville in Ulster County.

To contain the wildfire that started Saturday, two state police helicopters are dropping water on the hottest parts of the blaze. And bulldozers are being used for the perimeter operation.

More than 100 members of various local and state agencies were battling the fire, from parks employees and police to employees of the Department of Environmental Conservation.

They include the 40 additional emergency workers the governor ordered deployed on Sunday.
