The Verrazano-Narrows Bridge, along with the other three major Staten Island bridges, provide access to Staten Island from New Jersey, Brooklyn, Manhattan, and areas farther east on Long Island. Deer are able to swim the approximately 2 miles from New Jersey and other locations to the island.
Staten Island deer kill was backed by state and feds, Oddo says, SILive, Oct 4, 2017Ultimately the city decided to sterilize hundreds of Staten Island bucks. More than 875 vasectomies have been performed on them since the program began last year. An unrestrained deer herd can harm parks and private property, spread tick-borne illness like Lyme disease and wander into roads more often, increasing the risk for deadly vehicle collisions. Manipulating deer fertility is only permitted by the state as part of scientific research. The state Department of Environmental Conservation approved the city’s vasectomy program last year.
Huge jump in deer collisions on Staten Island, SILive, Sept 23, 2107Thirty-five collisions between vehicles and deer have been reported on Staten Island through August of this year and a city contractor is on track to remove more of their bodies from borough streets than in 2016, according to officials. A Sanitation Department contractor took 106 dead deer off city streets and other public property on Staten Island this year through Sept. 20, an agency spokesman said. The same contractor collected just 118 deer carcasses in the borough all of last year and 79 in 2015.
Solving Staten Island’s Deer Problem With a Snip and a Stitch, NYTimes, Sept 22, 2017 “People said it was just not logistically possible to capture this many deer and sterilize them,” said Sarah Aucoin, chief of education and wildlife for Staten Island’s parks department. “But we can tell you that it’s not logistically impossible. We are reaching the number of deer we were hoping for.” Staten Island oversaw 720 vasectomies last year, when the project launched, and they estimate that about 92 percent of the sexually active male deer on the island were sterilized. Last month, a six-person team began searching for the remaining adult bucks, as well as younger males, which they estimated to be about 250 in August.
Staten Island’s Deer Population May Not Have Dropped This Year, City Says, DNAInfo, July 20, 2017STATEN ISLAND — An aerial survey found 266 fewer deer living in Staten Island than last year, but officials warned it doesn’t necessarily mean the population has decreased. In February, the Parks Department conducted a second aerial survey that expanded to include the entire borough, instead of just focusing on parkland, the Staten Island Advance first reported. The latest survey found only 527 white-tailed deer in the borough, down from the 793 found in parkland in 2014, according to the Parks Department.
“The aerial surveys conducted in 2014 and 2016 confirmed that deer are present on Staten Island and illustrated expanding patterns of distribution, providing data necessary to the City’s deer management strategy,” a spokeswoman for the agency said in a statement.
However, the Parks Department said that it hadn’t found evidence of deer dying off or migrating out of Staten Island and the numbers don’t mean the population has decreased. The survey only gives a minimum population number for deer and the planes have a better chance of spotting the animals when flying on cloudy days, which they did in 2014. In 2016, the surveys were done on days with clear skies, Parks said.
70 deer vasectomies on Staten Island so far, SILive, Sept 15, 2016A city contractor performed 70 vasectomies on male deer in the 10 nights since the three-year effort to cut the white-tailed herd began on Labor Day, officials said.
Buckle up! Staten Island deer vasectomies begin Labor Day, SILive, Sept 2, 2016Anthony DeNicola of White Buffalo will begin sterilizing hundreds of male deer on Monday night in time for the whitetail rut this fall, City Hall said. The Parks Department is paying White Buffalo and DeNicola $2 million this year as part of the three-year plan to cut down the Island’s out-of-control herd.
D’oh! Just 527 deer on Staten Island in latest city count, SILive, July 14, 2016Only 527 deer were found on Staten Island during the city’s latest aerial survey of the herd — 236 less than the last count two years ago and well below what the city expected. The Parks Department insists that the data will nonetheless play a crucial role in plans to perform hundreds of vasectomies on borough bucks to help manage what is still believed to be an expanding herd.
New York’s Deer Vasectomy Plan is Absolutely Idiotic and Won’t Work, D+DH, Jun 21, 2016 “This plan has very low likelihood of success,” said Paul Curtis, another ecologist at Cornell who was part of the city’s interagency deer task force. A few bucks in Ithaca, N.Y. were given vasectomies as part of a multi-year study on deer controls in and around the campus there. “We could only do three vasectomies — it wasn’t safe for the deer and wasn’t safe for us,” Curtis said.
The Times, They Are A-Staying the Same, San Antonio Live, June 19, 2016So besides the fact that it’s impossible to get all the deer, and that one buck could impregnate pretty much all the does on the island, and the fact that tranquilizing deer is often fatal, not to mention expensive and time consuming and dangerous for the people doing it, besides all that, the very idea is contrary to its own purpose, which is to accord the deer the same rights as people.
New York Mayor Supports a Very Different Kind of Birth Control Program, Wayne Pacelle’s Blog (HSUS), May 12, 2016Staten Island’s multifaceted approach will include sterilization, education, and the protection of natural resources, and is “smart, effective, and humane,” Mayor de Blasio said in a press release. “We’re confident this is the best plan to ensure the safety and happiness of Staten Islanders who have been affected by the growing deer population,” he added. The city hopes to reduce deer vehicle collisions, vegetation and habitat loss, and personal property damage. The public education component of the plan will include outreach on topics, including public health issues such as tick-borne disease transmission. The deer population itself will be addressed with surgical intervention, by giving vasectomies to males in the herd.
Sterilize Staten Island’s male deer: City unveils plan to cut the herd, SILive, May 9, 2016The Parks Department plans to sterilize hundreds of male deer to help manage Staten Island’s out-of-control and expanding herd, starting as soon as this fall’s rutting season if the plan is approved by the state. “We do aim to get all of them in order to completely limit the reproduction,” said Sarah Aucoin, Chief of Wildlife and Education at Parks. The three-year effort is expected to eventually reduce the borough herd 10 to 30 percent. The city would spend $2 million this first year, with the annual cost going down as fewer males are left to sterilize.
Why are there so many deer on Staten Island? Watch this video to see how they get here, SILive, Feb 3, 2015In most cases, the population of a newly arrived species grows, as long as there is enough food to support healthy numbers. The maximum number of animals that can be supported by the resources in an area is called the carrying capacity. A new population usually overshoots the carrying capacity slightly, then levels off near the number of healthy animals that can be sustained. But variations in the carrying capacity, from changes in resource productivity, the population of predators and disease, may affect the animals’ population size from year to year.
