Dennstaedtia globulifera (IV= 21.75 %) occurring in 83 % and 100 % of the plots (Table 2).

Los helechos usualmente se encuentran en ambientes mas humedos como las exposiciones norte y noreste asi como en los margenes de arroyos; se encontro Alsophila firma, un helecho de tipo arborescente, asi como otros propios del estrato arbustivo como Marattia weinmanniifolia, Ctenitis melanosticta,
Dennstaedtia distenta, Diplazium franconis y Lophosoria quadripinnata.
Penrod & McCormick (1996) observaron que en bosques mixtos de robles en Pennsylvania, el banco esporal de
Dennstaedtia punctilobula disminuia su viabilidad con la distancia, oscilando los valores maximos y minimos entre 4 y 50m respectivamente.
Hayscented fern (
Dennstaedtia punctilobula) also was abundant throughout the understory due to excessive herbivory from historically high white-tailed deer densities (Keyser and Ford, 2005).
