The city says there are fewer deer on Staten Island and credits a sterilization program for the decline.
The Parks Department says the borough's overall deer population has dropped from 2,053 deer in 2017 to 1,884 this year.
Births are also down more than 50 percent.
"We expect those declines to continue, and they will, in turn, cause the impacts to decline," said Sarah Aucoin, chief of education and wildlife with the city Parks Department. "That is our expectation and our hope. Fewer deer collisions, less of an impact on the environment."
The Parks Department is also working to protect the ecosystem on Staten Island. It is placing fences around planted forests and installing deer-resistant plantings.
