The Spontaneous Vascular Plant Flora of New York's Central Park

This work details the spontaneous vascular plant flora of New York City's Central Park for the period 2013 to 2017. We divided the 341-ha (843-acre) park into 36 zones and used a modified timed-meander sampling method to collect herbarium specimens and silica-dried samples (for DNA analysis) of...

Description
Summary:This work details the spontaneous vascular plant flora of New York City's Central Park for the period 2013 to 2017. We divided the 341-ha (843-acre) park into 36 zones and used a modified timed-meander sampling method to collect herbarium specimens and silica-dried samples (for DNA analysis) of spontaneous, naturalized plants. We collected each new species until we ceased to find any species that had not been previously encountered in any zone. We collected 1,468 specimens, representing 438 species and two subspecific taxa from 262 genera and 89 families, and a number of cultivated species not analyzed is this work. We find that 45% of the flora are native (198 species) and 54% (240 species) are nonnative. Three species are of unknown native status (
