NYBG EcoQuest November 2017 - Week Two
INVESTIGATE INVASIVES!
November 1–14
Twenty-four naturalists have made one hundred and thirteen observations of Common Reed (Phragmites australis), Japanese Angelica Tree (Aralia elata), Italian Arum (Arum italicum) and Porcelain-berry (Ampelopsis glandulosa) and associated organisms. A new infestation of Italian arum was just discovered on the Bronx River in Westchester county. This is a new county record. Until they are eradicated, these plants pose a threat downstream in the Bronx.
Observations: 113
Places: Manhattan, 45; Bronx, 32; Queens, 24; Staten Island, 11; Brooklyn, 1.
Observers: @susanhewitt, 31; @bioethics, 15; @mpitaro, 13; @cbarron, 11; @laura622, 7.
