Four Season Virtual Tree Trail

Station Ten - Bitternut Hickory    Carya cordiformis

 

Like other hickories, the bitternut hickory is a member of the Walnut Family.  It normally reaches a height of around 100 feet and a trunk diameter of 2 or 3 feet.  It ranges over much of the eastern United States, with the exception of most of Florida and the Gulf Coast.  Its range extends farther north than any of the other hickories.

 

Habitat:  Moist soils along streams; occasionally in drier uplands.

  Bitternut Hickory Leaf

Identification:  The leaves are 6 inches to 10 inches in length, and are alternate, pinnately compound, shiny above and paler and lightly hairy below.  Each leaf has 7 to 11 sessile leaflets.   The margins of the leaflets are serrate.  The rachis is slender and slightly hairy.  Compare these leaves to those of the Shagbark Hickory, and to those of the White and Blue Ashes.  Note the alternate pattern of the leaves and branches, which distinguishes this tree from the ashes, which are opposite.

 

   
 
Bitternut Hickory Bark

 

The bark of the Bitternut Hickory is a slate gray.  In older trees the bark becomes shallowly fissured with interlacing ridges.

 

 

 

 

 

 

 

 

This species is monoecious, with both male and female catkins appearing on the same tree.  You may want to use binoculars to help spot the catkins.

 

Other Uses and Lore: 

The wood of the bitternut hickory has been used for tool handles and agricultural implements.  It is also used in the curing process for curing hams and bacon.   Early settlers pressed an oil from the nut, which some used as a remedy for rheumatism, while others used it to fuel crude lamps.

 The nuts are eaten by a wide variety of wildlife, including wild turkey, squirrels, small rodents, raccoon, and white-tailed deer.

 

 The Trail From Station Ten to Station Eleven

American Toad

From Station Ten, the trail is pretty flat as it traverses the bottomland area near the river.  As you cross this wetter area and approach the river, listen for the long high trill of the American Toad.   These amphibians begin calling in early March and continue calling through the spring months.  It is a short distance to Station Eleven, and it will be on the left side of the trail.
