The Ridgefield Deer Management Implementation Committee has held a public hearing about the future of controlled hunts.  When the hunt was started in 2007, the goal was to cull the herd from near 70 deer per square mile, down to 20.  Ridgefield officials say a count done last year found the deer population down to about 40 per square mile.  Members of the Conservation Committee asked if it's possible for the hunt to be paused, while others suggested alternating years.  Deer Committee members are concerned that the animal's population would quickly go back up to pre-hunt numbers.
