It isn’t easy being green in the Big Apple.  By some counts, New York City has lost 75% of its native plant species.  Most have been non-woody ground layer vegetation.  These herbaceous plants, frequently the vast majority of plant species diversity, appear to be acutely susceptible to natural and anthropogenic disturbances. The latter is especially germane on an archipelago teeming with 8 million humans.  Charting the health of this vegetation and threats to its continued survival is thus imperative.

Canada Mayflower (Maianthemum canadense) is a good plant to notice. Its presence an indicator of a thriving mesic hardwood forest.

Wild bean (Apios americana). Herbaceous, perennial, twining vine in the pea family (Fabaceae) found occasionally in the city (so a NYC rarity).  This one was found in a canopy opening in a moist forest.  I wonder why this isn’t available horticulturally?  Pelham Bay Park, Bronx.
