CERA Safety
Stay on the Trail!
Blazes, or painted rectangles on trees, are used along the trails in CERA to mark the path. Yellow blazes mark the Herbert Run Greenway trail and white blazes mark the CERA Interpretive Trail.
Blaze placement is meant to tell you the direction the trail is taking.
For example, a single blaze means the trail continues straight, while two blazes next to each other can mean the trail turns either left or right.
Watch out for Poison Ivy!
Poison ivy is a woody vine that can be found within CERA. Poison ivy can cause a skin rash that can be very itchy and painful. A common saying people use to remember how to identify poison ivy is “Leaves of three, let it be!”
The entire plant (leaves, stems, and roots) is poisonous, so you want to avoid touching any part of the poison ivy plant.
You can protect yourself by (1) staying on the trails, (2) wearing long sleeves, pants, and tall socks, and (3) knowing what poison ivy looks like so you avoid coming in contact.
Be Tick Smart!
Ticks are small animals that like can be found on leaves or grasses and can attach themselves to your skin by biting you. You can protect yourself from ticks by (1) staying on the trails, (2) wearing long sleeves, pants, and tall socks, and (3) checking for ticks after returning from your walk.
