Angelica Tree & Wisteria Control

Continuing with the wildlife habitat restoration priorities outlined in the Hilltop Reservation’s Master Plan and in its Invasive Plant Management Plan, Essex County has engaged a contractor to address the large infestations of Japanese angelica tree and Japanese wisteria on the Reservation’s eastern slope (Aralia elata and Wisteria floribunda, respectively).  The contractor is using a combination of foliar spray and basal bark application methods to treat leaves and stems (see photos below).  As these two species are very resilient, the contractor will be returning in early summer 2020 to ensure eradication.
