These ferns produce dense stands that prevent the establishment of tree seedlings. While this has been found to be beneficial in limited situations, such as under power-lines and on ski-area trails, these ferns are generally seen as detrimental to forest regeneration.Heather M. Engelman & Ralph D. Nyland (2006). "Interference to Hardwood Regeneration in Northeastern North America: Assessing and Countering Ferns in Northern Hardwood Forests." Northern Journal of Applied Forestry (Society of American Foresters) 23(3):166–175. Dennstaedtia Dennstaedtia punctilobula 2.jpg Dennstaedtia punctilobulahay-scented fern Hay-scented fern (Dennstaedtia punctilobula) is often considered to be an interfering species in New York forest understories, where large deer populations over-browse other native plants but avoid this fern, which prevents tree regeneration.Peter Smallidge (2015).

Most are allotetraploid, derived from diploid Dryopteris parents, including two of the New York diploid species, D. intermedia and D. goldiana, shown above. The other diploid parents, D. expansa and D. ludoviciana, are North American, but not New York natives. A fifth, likely extinct, diploid parent "D. semicristata" has been hypothesized to form the well-supported model used here. The species Dryopteris clintoniana is allohexaploid, resulting from the diploid D. goldiana (above) and the allotetraploid D. Cristata, below. The parentage of the introduced non-NY-native, Dryopteris filix-mas has not been resolved, but it is probably not part of the same North American "reticulate complex" as the rest.Emily B.
