Growing Regions

The range of sycamore extends from southwestern Maine west to extreme southern Ontario, southern Wisconsin, Iowa, and extreme eastern Nebraska; south to south-central Texas; and east to northwestern Florida and southeastern Georgia. It also occurs in the mountains of northeastern Mexico [30,35,50]. Sycamore has become naturalized to some extent from plantations outside of its native range, chiefly in southern Maine, southern Michigan, southern Minnesota, and eastern and southern Iowa [35].

     

General Information

The currently accepted scientific name for sycamore is Platanus occidentalis L. (Platanaceae) [13,35,48,50]. There are no accepted infrataxa. The London plane tree (P. xacerifolia [Ait.] Willd.) is a hybrid of Oriental plane (P. orientalis) and sycamore and perhaps includes a number of backcrosses [50,78].

Sycamore is found in quantity only in bottomland forests, particularly
of elm-ash-cottonwood (Ulmus spp.-Fraxinus spp.-Populus deltoides) types
as defined by Shifley and others [66], and cottonwood-willow (Salix
spp.) types.  It usually occurs singly or in small groups [78].
Sycamore is found occasionally along intermittent streams within upland
stands of oak-hickory (Quercus spp.-Carya spp.) communities.  It is a
major pioneer species in the floodplains of large rivers [74].  In the
Southeast pure stands of 40 to 100 acres (16-40 ha) are sometimes
formed; it rarely forms extensive pure stands in the northern parts of
its range [78].  In the northern states sycamore is rarely the dominant
species; it increases (replacing silver maple [Acer saccharinum]) with
decreasing latitude [27].

Sycamore is listed as a dominant or indicator species in the following

     of Maryland [14]
2) The natural communities of South Carolina [58]
3) Land Classification in the Blue Ridge province: state-of-the-science
     report [55]

     States [56]

     Forest, State Resort Park, and Wildlife Management Area in west
