The physical factors within the transition zone between the typical prairie association of the state and the deciduous forest communities occurring along the Des Moines River have been studied. The conditions for plant growth at the source of the river in northwestern Iowa have also been compared with those near the mouth of the river in southeastern Iowa. The purpose of this paper is to report the effect of the modification of factors on the distribution and grouping of woodland species and on the general reactions of the communities to the varying habitat factors.
