Nitrogen is Not Only Long Island Sound's Problem

Excess nitrogen is not only a problem for estuaries and coastal ecosystems like Long Island Sound, it's also helping make rare native plants even more rare. This article from the University of California at Irvine explains.

One eyebrow raiser: excess nitrogen "creates a competition among plants for space that drives rare plants – plants that are uncommon and not abundant – out of existence."

So that's what rare plants are! Plants that are uncommon and not abundant! Glad they explained it.
