Distribution Overview
Water hickory is found in low, wet woods from Texas east to Florida and north to southern Illinois and Virginia (distribution map). Individuals of this species can tolerate both a wetter site and a wider range of soil moisture levels than any other hickory, surviving on poorly drained, tight textured soils that are flooded in winter and parched in summer. It is a major component of two forest cover types: Sugarberry-American Elm-Green Ash and Overcup Oak-Water Hickory. In north Louisiana, water hickory is found in association with C. ovata and C. cordiformis on Guyton soils. The position of the species is distinct, however, with water hickory occupiing the lowest, wettest sites

Tallest of all the hickories
Comments
'bird pecks' leave residue
Deposits - Magnesium carbonate deposits are present in the wood, and 'Bird pecks' leave residue that crystallizes.
Deposits in the wood
This species is a True pecan, and can be separated from the True hickories by weight, and by the narrow bands of parenchyma, which appear between the rays and between the large earlywood pores. (In hickory the band occurs after the first row of earlywood pores.)
