“…Bracken is distributed worldwide, except in very cold or dry conditions and has become dominant in some grasslands [37,38]. Although it has deleterious effects on animals such as cattle and also on human health [39], its first sprouting is an important food item in East Asia, including Korea and Japan [40][41][42]. This is because its carcinogenic contents can be largely removed by boiling the harvested sprouts in water with wood ash or sodium bicarbonate [43].…”

Abstract:Once local expert knowledge regarding the harvesting of various non-timber forest products (NTFPs) is lost, it is difficult to recover. We investigated whether the knowledge of expert forest harvesters can be used to determine the habitat distribution and harvesting sites of three popular edible wild ferns, i.e., ostrich fern (Matteuccia struthiopteris), bracken (Pteridium aquilinum), and royal fern (Osmunda japonica), in mountainous communities of western Fukushima, Japan. Using multi-criteria evaluation (MCE) based on the analytic hierarchy process (AHP) and geographic information system (GIS), we found that harvesters were easily able to recognize differences in the spatial characteristics of the habitat distribution of fern species due to both natural and anthropogenic factors. These factors were described by various GIS layers, such as vegetation and terrain features (e.g., gradient, aspect, and slope position) derived from a 20-m digital elevation model (DEM). Harvesting sites were limited by their distance from a roadway, which differed among species. By comparison with the GPS records of actual harvesting sites, we estimated the potential harvesting sites of each fern species with reasonable accuracy, particularly for bracken. Our results show that the knowledge of expert forest harvesters can be quantified using MCE and GIS, which is useful for determining the spatial characteristics of NTFP harvesting and ensuring sustainable management practices.

“…A good number of species of this plant group are used as ornamentals and medicinals (Nayar, 1957;Benerjee and Sen, 1980;Dhiman, 1998;Dixit, 1974Dixit, & 1975Hodge, 1973;Kaushik, 1998;Singh, et al, 1989). Many pteridophytes occurring in Bangladesh are also reported as ethno-medicinally useful (Uddin, et al, 1998;Uddin, et al, 2008;Sarker and Hossain, 2009).…”

Pteridophytes growing in the Rajkandi Reserve Forest of Moulvibazar district were indentified and a total of 52 species belonging to 30 genera of 20 families have been documented. The family Pteridaceae with nine species was found to be the largest, which was followed by Polypodiaceae with seven, Tectariaceae with six and Thelypteridaceae with five species. The genus Pteris with six species was found as the largest, which was followed by Tectaria with five and Bolbitis, Lygodium and Selaginella, each with 3 species, and the rest of the genera consisted of two or one species. Most of the species were recorded from the woodlands and three species, viz., Tectaria chattagramica and Cyathea gigantea enlisted in Red Data Book of Bangladesh (Khan et al., 2001), were found as common in this reserve forest.

“…They have also been used for food, fiber, crafts, building materials, abrasives, decoration, and apart from their use as medicine [6][7][8][9][10][11][12][13][14][15] . Recently interest in ethno botanical studies of fern and their allies have attracted a number of researchers and they have supplied a lot of information about different uses worldwide [16][17][18][19][20][21][22][23][24][25][26] .…”
