Officials plan to reduce the number of Canada geese in New York State by two-thirds, eventually trimming the population to 85,000 from 250,000, according to a report prepared by several city, state and federal agencies.

The reduction is part of a larger plan that also calls for the near halving of the Canada geese population in 17 Atlantic states, to 650,000 from 1.1 million. The New York Times obtained a copy of the report.

In New York City, the report says, the current goose population of 20,000 to 25,000 is “five times the amount that most people would find socially acceptable,” suggesting the number would be reduced to about 4,000.

A high-level official of the United States Department of Agriculture who is familiar with the proposal called it a “one-of-a-kind plan.”
