Summary: These wooded vernal pools are small shallow circumneutral freshwater wetlands of glacial origin that partially or totally dry up as the growing season progresses. They are documented to occur in northern Idaho and western Montana. These vernal ponds and wetlands usually fill with water over the fall, winter and early spring, but then at least partially dry up towards the end of the growing season. Depending on annual patterns of temperature and precipitation, the drying of the pond may be complete or partial by the fall. These sites are usually shallow and less than 1 m in depth, but can be as much as 2 m deep. The pool substrate is a poorly drained, often clayey layer with shallow organic sediments. The freshwater ponds have pH ranges from 6.2 to 7.8 with most measurements between 6.5 and 7.5, i.e., relatively neutral. The ponds in Montana were thought to be isolated, but it has been shown that in high water years the ponds spill over, and there is an exchange of surface water between ponds. The pools have a ring of trees surrounding the ponds that provide shade and influence their hydrology. A variety of tree species dominant the upper canopy, including Abies grandis, Abies lasiocarpa, Larix occidentalis, Picea engelmannii, Pinus contorta, Pseudotsuga menziesii, and the broadleaf trees Populus balsamifera ssp. trichocarpa (= Populus trichocarpa), Fraxinus latifolia, and, to a lesser extent, Populus tremuloides and Betula papyrifera. Common shrubs include Alnus incana, Cornus sericea (= Cornus stolonifera), Rhamnus alnifolia, and Salix spp. Alopecurus aequalis, Callitriche heterophylla, Carex vesicaria, Eleocharis palustris, and Phalaris arundinacea are common herbaceous plant associates.
