HASTINGS-ON-HUDSON — Heavy snow and red tape resulted in a disappointingly slow start for a pioneering program in a New York suburb to use birth control as a no-kill way to thin the numbers of deer.
Hastings-on-Hudson Mayor Peter Swiderski said that out of 120 deer, only eight doe were tranquilized, tagged and injected with birth control over the monthlong program in March, seven in the final week alone. That was far short of the goal of injecting 40 to 50 does in the first two years.
“It was certainly a humbling experience but we were encouraged in that it was such a strong finish,” the mayor said, adding that officials were committed to the program and trying again next year.
Deer have overrun this 2-square mile village of 7,900 people about 16 miles north of Manhattan, scouring foliage in the park, munching gardens and causing more than a dozen car crashes a year. But residents have resisted lethal methods of culling the herd.
Announced last year, the project is the first birth-control study of a free-roaming deer population in an open, suburban area in the U.S. Workers from the Humane Society of the United States had hoped to start tranquilizing the doe with air guns in February and obtained permission from the state, but they were delayed by both the harsh winter and bureaucratic regulations.
Allen Rutberg, director of the Center for Animals and Public Policy at Tufts University and the architect of the program, said heavy snows pushed the deer out of public Hillside Park, where the team hoped to do most of its work, and into mostly private yards.
That meant officials had to launch a door-to-door effort to get consent from every property owner. It resulted in permission from 340 households and just two rejections, Swiderski said, reflecting broad support for the program, along with some skepticism about whether it will work.
“They know there’s no alternative for us,” the mayor said. “You can’t walk around on quarter-acre zoning with a crossbow.”
People who agreed to let the Humane Society’s experts on their property were given red flags to display.
“There’s a flag in my yard and most of my neighbors, to the left and the right, have little red flags,” said resident Nancy Balaban, who has had to surrender her garden to the deer.
