The environments in which native orchids grow were examined in terms of factors which might determine the survival and reproduction of the various species. Soil tests were made for 34 species now known to be growing in Rhode Island. Soil reaction appears to be related to growth of orchids, but other factors in the environment were found to be of equal if not greater importance. These include light, moisture, temperature and destruction by animals. Fertility was not found to be limiting under the conditions observed.
