The Holiday Tree Thief

Dec 18, 2017

You might steal a kiss under its green branches, but in nature, mistletoe is a parasitic plant that attaches to and steals nutrients from trees. It's not a complete parasite as its leaves can convert sunshine into energy. And it's not a complete bum as its flowers, fruits, and leaves provide many benefits.

The white berries which you see around Christmas are toxic to humans and some animals, but provide food when it’s scarce for mammals like deer, elk, squirrels, and chipmunks. Chickadees, bluebirds, robins, and other birds eat the berries and spread the sticky seeds in their droppings or by wiping them off on branches. Seeds will tap into tree branches and trunks and create a pipeline drawing out water and minerals as the plant grows.

Mistletoe grows naturally in southern Missouri in clumps high up on trees. It's rare in Missouri but can be found in river valleys on sycamore, elm, river birch and oaks. It grows in tangled balls as much as five feet across. House wrens, chickadees, mourning doves, and other birds build nests in them. Squirrels will set up house there, too.

Three types of butterflies rely on mistletoe for survival. The great purple hairstreak, found in Missouri, lays its eggs on mistletoe and the young eat the leaves. Adults feed on the nectar, as do some native bees.

Mistletoe has been used as a folk remedy for centuries and is currently being studied for cancer treatment. The oak mistletoe, our most common, was once believed to extinguish fire. This comes from an earlier belief that a flash of lightning brought mistletoe to trees.

Mistletoe can overtake and kill some trees and flowering shrubs. The dead trees will also provide nesting homes for birds and wildlife. Mistletoe is a beneficial parasite that feeds and shelters wildlife and fills our homes with greenery and joy during the holidays.

Learn all about this popular holiday plant with these facts from The National Wildlife Federation

  • There are 1,300 mistletoe species worldwide. The continental United States and Canada are home to more than 30 species, and Hawaii harbors another six.
  • All mistletoes grow as parasites on the branches of trees and shrubs. The genus name of North America’s oak mistletoe—by far the most common species in the eastern United States—is Phoradendron, Greek for “tree thief.”
  • Mistletoes produce white berries, each containing one sticky seed that can attach to birds and mammals for a ride to new growing sites. The ripe white berries of dwarf mistletoe, native to the western United States and Canada, also can explode, ejecting seeds at an initial average speed of 60 miles per hour and scattering them as far as 50 feet.
  • The mistletoe’s white berries are toxic to humans but are favored during autumn and winter—when other foods are scarce—by mammals ranging from deer and elk to squirrels, chipmunks, and porcupines. Many bird species, such as robins, chickadees, bluebirds, and mourning doves, also eat the berries.

Why Healthy Deer Matter and How You Can Help

Nov 04, 2018

WHY HEALTHY DEER MATTER AND HOW YOU CAN HELP:  Over the last 100 years, Missouri's white-tailed deer were brought back from an all-time low of 400 to more than 1.2 million today.  They're one of our most valuable species for outdoor recreation, jobs and tourism.  The work of keeping our deer herd healthy today is as important as the early work to restore them.  Scientists work with hunters and landowners to prevent the spread of disease, especially Chronic Wasting Disease (CWD), which is always fatal.  Learn more about deer health, CWD, and mandatory testing in this week's Discover Nature Note.
