Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Green Hawthorn - Downy Hawthorn Ruderal Shrubland

Colloquial Name: Ruderal Hawthorn Bottomland Shrubland

Hierarchy Level:  Association

Type Concept: Shrublands (conceptually approaching short forests) dominated by variable composition of Crataegus viridis, Crataegus mollis, or mixtures of the two. Other associated species include Celtis laevigata var. laevigata, Diospyros virginiana, Ilex decidua, Laportea canadensis, Parthenocissus quinquefolia, Ulmus alata, and Smilax rotundifolia. This association occurs as a successional type in old pastures and old fields in bottomlands, and is reported from localized areas in east-central and eastern Oklahoma.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: In Oklahoma, this apparently represents the temporarily flooded part of Hoagland''s type (Crataegus crus-galli - Ilex decidua - Crataegus viridis shrubland association in Hoagland 1997). Crataegus viridis and Crataegus mollis occur together in the bottomlands (B. Hoagland pers. comm.).
