Fern Diversity in the Satpura and Maikal Ranges of Madhya Pradesh
Ferns form a quiet but important part of central India’s hill flora. The Satpura and Maikal ranges give them moist ravines, rocky slopes, and forest shade. As a result, these mountains support more pteridophytes than the surrounding dry plains.
The Satpura range runs across southern Madhya Pradesh. Pachmarhi, Tamia, and Patalkot are especially rich. The Maikal range continues east toward Amarkantak and the upper Narmada. Together, these hills create cooler microclimates. Therefore, ferns can survive in a region that is otherwise seasonal and dry.
Published surveys from the Satpura hills report a large set of ferns and fern allies. Some studies list around ninety taxa. Common families include Thelypteridaceae, Polypodiaceae, Pteridaceae, Athyriaceae, and Aspleniaceae. Frequent genera include Asplenium, Pteris, Adiantum, Athyrium, Nephrolepis, and Cheilanthes. In addition, tree ferns such as Cyathea gigantea and Cyathea spinulosa occur in sheltered sites.
The flora is biogeographically mixed. Some species also grow in the Himalaya. Others are shared with South Indian hills. A smaller set appears in both regions. Hence, the Satpura–Maikal belt acts as a meeting ground. Pachmarhi is often described as the best example of this mix.
Habitat decides where ferns grow. Most species prefer shady ravines, stream banks, and the interior of moist deciduous forest. Rock crevices hold drought-tolerant forms such as Actiniopteris and Cheilanthes. Epiphytic ferns remain few. In contrast, terrestrial species dominate the ground layer during the monsoon.
Local use adds another layer of interest. Tribal and rural communities in Chhindwara, Hoshangabad, Mandla, and Amarkantak use several pteridophytes in traditional medicine. Adiantum, Selaginella, Dryopteris, and Tectaria appear in such records. However, harvest should stay limited. Many ferns occupy narrow habitats and recover slowly.
Threats are rising. Forest cutting, fire, road building, and tourism disturb moist pockets. Climate stress can also dry ravines earlier in the year. Consequently, rare and moisture-dependent species face higher risk. Tree ferns and shade-loving spleenworts need special watch.
Future work should combine field surveys with herbarium checks and GPS mapping. Researchers can compare Pachmarhi with Maikal sites such as Amarkantak. They can also study phenology after the monsoon and track habitat loss. In this way, fern diversity becomes a tool for conservation planning, not only a list of names.
The Satpura and Maikal ranges therefore offer a compact laboratory for Indian pteridology. They hold tropical and temperate elements in one landscape. They also show how topography protects fragile plants in central India. Careful documentation can still save that richness.
