Crataegus (aestivalis, opaca, rufula) Seasonally Flooded Forest Alliance

accession code: VB.CC.24043.CRATAEGUSAESTIV

Southeastern Ecology Working Gro... |

This alliance includes communities dominated by one or more of the mayhaws, Crataegus aestivalis, Crataegus opaca, and/or Crataegus rufula, occurring in seasonally flooded depressions, which may occur either in floodplains or in uplands of the Coastal Plain of the southeastern United States. The mayhaws often dominate seasonally flooded depressions, and are small trees to 12 m tall and to at least 30 cm dbh. Canopy coverage in mayhaw ponds may vary from a closed canopy to an open, scattered, or zonal canopy of mayhaw. In the Florida Panhandle and adjacent portions of Alabama and Georgia, the various nominal species can occur intermixed. Crataegus aestivalis occurs from southeastern North Carolina through South Carolina and Georgia to northern peninsular Florida and eastern Panhandle Florida. Crataegus opaca occurs from eastern Texas east to southern Alabama and extreme western Panhandle Florida. Crataegus rufula occurs in southwestern Georgia, southeastern Alabama, and Panhandle Florida. Mayhaw forests occur in broad depressions of the central flatwoods of the Florida parishes of eastern Louisiana. The distributions of mayhaw communities are not very well understood. |

This woodland association is know only from Canyonlands National Park and Glen Canyon National Recreation Area but likely occurs elsewhere on the Colorado Plateau in Utah. Stands occur on the deep soils of plateaus, stream terraces, benches, and wash banks. Sites are on flat to gentle slopes between 1362 and 1865 m elevation. Bare soil or litter cover most of the unvegetated surface, depending on density of the vegetation and degree of disturbance. Dead wood and biological soil crusts provide sparse to moderate cover. Soils are rapidly drained sandy loams or loamy sands derived from alluvium or eolian deposits. The vegetation is characterized by an open canopy, typically 2 to 5 m tall, of <i>Juniperus osteosperma</i> with 6 to 30% cover, and an understory dominated by <i>Mahonia fremontii</i> with 3 to 12% cover; total vegetation cover ranges from 23 to 61%. Associated shrubs include <i>Rhus trilobata, Ephedra viridis, Atriplex canescens, Symphoricarpos longiflorus, Yucca angustissima</i>, and <i>Gutierrezia sarothrae</i>. Herbaceous species provide sparse cover and may include <i>Achnatherum hymenoides, Pleuraphis jamesii, Aristida purpurea, Sporobolus airoides, Machaeranthera canescens</i>, and <i>Lepidium montanum var. jonesii</i>. Biological soil crusts are well-developed but sparse in some stands and provide up to 43% cover in others. |
