Upcoming Workdays

Vine Cutting Work Day
Saturday, 2/17
9 am – 1 pm
Blue Bell Hill Parking Lot

There are many types of vines commonly found in the park and most are invasive, causing lots of damage to our already fragile tree canopy. Vine species like Oriental Bittersweet, Wisteria, Honeysuckle, and English Ivy are all aggressively invasive and will be targeted during the workday. At this workday, you will learn how to identify these vines and how to remove them. Additionally, you will learn how to identify and avoid Poison Ivy and why it is a beneficial native plan that we like to keep around.

Register for this work day here.
