Moist to wet deciduous or mixed conifer-hardwood forests, often in springy or seepy sites or along streams; conifer swamps; very local, especially southward.
A much more delicate and slender plant than Equisetum arvense, shade forms of which are often mistaken for it. Fertile stems are rarely collected and poorly known. Branching of the fertile stems after the strobilus is spent seems more erratic and irregular than in E. sylvaticum. Occasional fertile stems may not develop branches and simply wither, but this requires more field observations. The internodes of the main stem of E. pratense are finely papillose-roughened, even on the fertile stems.
