To date, Staten Island has invested $4.1 million into their sterilization project, according to reports released Friday. The city hired wildlife contractors White Buffalo to carry out the project in 2016. It would be the world’s first attempt to curb deer by sterilizing only males, according to media reports. The borough’s herd reached approximately 2,053 individuals in 2017 which amounted to an 8,454% increase in less than a decade.
