Populations have increased tenfold in the past two decades, leading to a new national strategy to halt the rapid spread
Populations of feral deer have increased tenfold in the past two decades with numbers now too high to be managed by recreational hunting or other recent control measures.
Numbers of the invasive species are now so large in some parts of the east coast that a new national strategy by federal and state governments proposes establishing a “containment zone” to stop the spread of the animals westward across the country.
