Piedmont Mesic Forests


Piedmont Mesic Forests grow in cool, shaded sites such as north-facing slopes, within ravines, and on high terraces by streams. These sites are evenly moist but not saturated.  Indicator species are American beech, northern red oak, and tulip-tree.   Soils here tend to be deeper and richer than those of oak-pine-hickory forests, fostering greater diversity.   These forests rarely experience large scale natural disturbance, so trees can grow old and huge.  Mesic forests growing over fairly acidic rock are sometimes called "beech forests".   Basic mesic forests grow over nutrient-rich amphibolite or marble, and have more diversity and lush growth.  Indicator species for the more basic soils include  white basswood, white ash, and southern sugar maple.  
​
What's special:  These forests, especially  those over basic rock, host beautiful spring wildflowers before the trees leaf out.  T
he moisture, and nutrients  encourage a lush diversity of trees and wildflowers and support a rich animal life, with many amphibians. 
Landscapes
​
​Conservation:  Mesic forests experience a small-patch disturbance pattern, in which shade tolerant saplings live for long periods under the canopy, and grow into the canopy  (are "released") when a small gap is created by an individual tree or large limb falling to the ground, allowing in more light.   Prescribed fires, which can destroy larger patches of trees in a single event, should be kept from reaching the mesic forests.

Grades to Oak-Pine-Hickory Forest sites as grow drier..  Grades to Bottomland Forest near floodplains.
