This blog post is about the different habitats, wildlife and plants at Livermore Falls.

Presence of Poison Ivy

Let’s face it; many of us have had our run ins with poison ivy, but have you ever wondered if there are ecological benefits of the plants? Poison Ivy (Toxicodendron radicans) is actually vital to the environment and has several important roles. Poison ivy roots are like a spider web, only stronger. They hold the soil in place very effectively and prevent water and wind erosion. This is especially important near the Pemigewasset River, where floods occur. There are no dams in place above Livermore Falls, which increases the chance of floods. In addition to this ecosystem service, poison ivy produces a berry in the fall season. Many birds rely on the berry, and if you ever wondered how poison ivy spreads, you can now blame it on the birds.

There is an abundance of poison ivy at Livermore Falls, but do not let this scare you off! As long as you stay on the paths, you will not encounter poison ivy, but it is important to know it is there and how to identify it.

Myths Versus Facts

There are many myths about poison ivy; so let’s set the record straight. First and foremost, poison ivy, poison sumac and poison oak all have the same oil called “urushiol.” This oil is what gives people an allergic reaction, or rash.

  • Myth: Scratching Poison ivy blisters will spread the rash.

Fact: The fluid from your blisters will not spread the rash. The rash can only be spread by urushiol. That is why it is important to clean any infected area to remove the oil.

  • Myth: Poison ivy rashes are contagious.

Fact: The rash itself is not contagious, however if the oil is still on the infected area, it can easily spread the rash.

  • Myth: After an initial reaction, I cannot get a poison ivy rash ever again.

Fact: Although we wish this were true, it is not. People generally become more sensitized with each encounter and can therefore have worse reactions to poison ivy.

  • Myth: Once allergic, always allergic to poison ivy.

Fact: A person’s sensitivity changes over time. Sensitivity can even change from season to season. Just like any allergy, if you were allergic as a child, you may grow out of it as an adult, or experience worse cases.

  • Myth: Dead poison ivy plants are no longer toxic.

Fact: The oil, urushiol, can remain active on a surface for up to five years! Avoid handling dead poison ivy and wash any surface that comes in contact with it.

If you plan to spend time at Livermore Falls, or anywhere in the outdoors, it is important to be able to recognize poison ivy, poison sumac and poison oak. Poison ivy has 3 pointed leaves that are mostly green, but can also be red. The leaves are shiny, due to the urushiol. The plant can vary in form which means poison ivy can grow low to the ground, or as a vine high above your head. If you came in contact with one of the three plants, immediately wash the infected area with soap and water; the sooner the better! (

Rule of Thumb: Leaves of 3, Leave it be!
