Three ecological environments (cultivated plots - palm groves, fallow plots and forests) were selected in order to study the distribution of Pteridophytes (fern plants), and also to study the evolution of these species over the age of crops (palm groves) in Southeast Côte d’Ivoire. The study site which contains these ecological environments has an area of 29710 km2 . A distinction was made between plots grown in village-based cultivated plots and industry-based cultivated plots. The results showed that only the forests are ecological communities that have the largest number of Pteridophytes and more the aged that the palm groves are, the greater number of Pteridophytes they contain. Forests are the development of supportive environments Pteridophytes, so it is important to protect these ecological environments (forests) to maintain these taxa.
