For example, by increasing light levels, thinning of mesic floodplain and hillslope forests could increase the density, biomass and cover of the ferns Thelypteris noveboracensis and Dennstaedtia punctilobula
and the grass Brachyelytrum erectum at the expense of a more diverse ground-layer flora (Horsley 1977), a generally undesirable condition when managing for system diversity.
Six sites, in which the herb/shrub stratum was dominated by the clonal ferns Dennstaedtia punctilobula
and Osmunda claytoniana, were randomly located within Harvard Forest property.
Six sites were chosen for study that had a prominent fern stratum composed primarily of Dennstaedtia punctilobula (hayscented fern) and Osmunda claytoniana (interrupted fern).
2] plots randomly located within clones of both Dennstaedtia punctilobula and Osmunda claytoniana.
Other species that occurred frequently in relatively high biomass in 1995, but were not identified in 1968, were Rubus alleghaniensis, Dennstaedtia punctilobula and Clematis virginiana.
