An enumeration of the pteridophytes in the lowland (60-600 m) part of a tropical rain forest of Khao Nan National Park, Nakhon Si Thammarat Province, southern Thailand, is presented and is the first report for the area. A total of 418 specimens of pteridophytes were collected and classified into 205 species from 27 families, the highest pteridophyte biodiversity in lowland Thailand and likely highest overall biodiversity region for pteridophytes in Thailand. Although ferns dominated at all taxonomic levels, fern allies were significant accounting for ~7% of all species found. According to habitat types, the specimens can be classified into 4 groups: terrestrials (116 species), epiphytes (27 species), lithophytes (81 species), and aquatic plants (1 species), although 19 species were found in more than one habitat. Two species are new records for Thailand, i.e. Huperzia carinata (Desv. ex Poir.) Trevis. var. laxum (C. Presl) Christ and Selaginella commutata Alderw., but were found onl...
Pteridophyte Flora of Huai Yang Waterfall National Park, Prachuap Khiri Khan Province, Thailand
A total of 128 species of ferns and fern allies belonging to 63 genera and 26 families were recorded from Huai Yang Waterfall National Park, Prachuap Khiri Khan Province. This is the first report for the area which includes 11 species in 4 genera from 3 families of fern allies. Three families of true fern, namely Polypodiaceae, Aspleniaceae and Thelypteridaceae are among the common families. Polypodiaceae included 28 species in 15 genera. Whilst Aspleniaceae and Thelypteridaceae included 11 and 10 species, respectively. The study area is 161 km 2 and the elevation ranges from 100-1,250 m. The vegetation is divided among Dry Evergreen Forest, Mixed Deciduous Forest, Tropical Evergreen Forest, and Hill Evergreen Forest. It was found that Hill Evergreen Forest has the highest number of pteridophyte species. The collected specimens have produced new information on pteridophyte distribution of the Malesian elements. The overall pteridophyte number in the national park represents about 20% of the total in Thailand.

Biodiversity of small islands, particularly in tropical region, always encourages scientific curiosity. Such curiosity is much greater when the small island of interest has been through various land use changes, such as in Karimun Besar Island. This island is one of thousand islands in Riau Islands Province, Indonesia and poses different land uses. However, studies on the biodiversity of flora in this island have not been recorded, including for pteridophyte or fern members. This study aimed to examine the diversity, floristic structure and composition of pteridophyte at six different study sites in Karimun Besar Island representing varying habitat conditions (i.e., primary forest, secondary forest, rubber plantation, road side, coastal area and mined land. The sampling was collected by using transect method to measure density, dominance and frequency. A total of 32 species of pteridophytes were recorded from the six study sites that belong to two divisions, Polypodiophyta (31 species) and Lycophyta (1 species). The number of species of pteridophyte varied across the six habitats. The highest number of species (21) was found in primary forest, while the lowest (9 species) was found in rubber plantation. The dominant species for each study site were Taenitis blechnoides (Pteridaceae) (rubber plantation), Dicranopteris linearis (Gleicheniaceae) (secondary forest), Sticherus truncates (Gleicheniaceae) (primary forest), Pteridium caudatum (Dennstaedtiaceae) (road side), Achrosticum aureum (Pteridaceae) (coastal area) and Nephrolepis hirsutula (Nephrolepidaceae) (mined land). The result of this study provides the first data of fern in Karimun Besar Island that support pivotal information on the biodiversity of small islands in tropical region.
Diversity of Ferns (Pteridophyta) in the Several Mountains of West Java
BIOLINK (Jurnal Biologi Lingkungan Industri Kesehatan)
The diversity of ferns (Pteridophyta) in the five mountainous in West Java (Mt. of Patuha, Papandayan, Tangkuban Perahu, Pangrango, and Guntur) has not been widely reported. The aim of this research was to obtain data on diversity and similarity of fern species in the five mountains in West Java. This research was conducted by exploring and descriptive analysis method. Comparison of species diversity among all reseach field were calculated by the index of species similarity according to Sorenson. The diversity of ferns in Mt. Patuha, Papandayan, Tangkuban Perahu, Pangrango, and Guntur were 27, 14, 26, 40 and 5 species, respectively. The total number of ferns species in five locations are 83 species from 25 families. Comparison of species diversity among fileds based on the Sorenson similarity index is low (<50%), except between the Mt. Patuha and Mt. Papandayan areas is high (> 50%).

Pteridophytes are vascular, spore-bearing plants, which are composed of ferns and their allies. Although commonly used in horticulture, it is also known to have medicinal values. This study identified the fern species present in Kalikasan Park, a forest fragment adjacent to Bicol University main campus in Legazpi City, Philippines. The Line Transect Method was employed wherein a 50 m transect line with an alternating 5x5 meter plot was set in the two sampling sites. A total of 14 fern species belonging to nine families and nine genera were found in the two sampling sites. Shannon’s Index of Diversity (H’) value of 2.08 and an Evenness (E) value of 0.8354 were recorded in sampling station 2. The anthropogenic disturbance and infrastructure expansion without clear-cut boundaries is a challenge to the fern population in the area. It is recommended that a comprehensive plan to safeguard the biodiversity of Kalikasan Park and of the university’s main campus be put in place.

Pteridophyte Flora of Manaslu Conservation Area, Central Nepal
The pteridophytes comprising ferns and fern allies constitute an important part in Nepalese flora. Pteridophyte flora of the Himalayan region is considered to be the basic requirements for the knowledge of pteridology. This paper aims to provide the overview of fern and fern allies present in the Nubri valley and its adjoining areas of Manaslu Conservation Area (MCA), Central Nepal. A total of 105 species belonging to 45 genera were recorded, with Dryopteris as the largest genera including twelve species followed by Athy-rium, Pteris and Polystichum. With regard to habitats, most of the species were terrestrials followed by lithophytes and epiphytes.

International Journal of Fauna and Biological Studies, 2017
Akamala forest station belongs to Machad forest range in Thrissur district. No literature is available regarding the diversity of flora and fauna of this forest range. The current study focuses on the diversity of pteridophytes in the Attoor beat of Akamala forest station. The survey has been carried out from June 2015 to August 2016. A total of 24 species of pteridophytes were collected from the study area. Floristic analysis of collected specimens was carried out to find out the families, genus and species. The collected species belonged to17 genera, 14 families and 2 classes. Except different species of Selaginella ((Lycopsida) all other members belonged to the class Filicopsida (Fern group). The most frequently represented species were Selaginella, Adiantum, Hemonitis and Pteris. Most of the collected species were terrestrial. Epiphytes, lithophytes and aquatic species were also reported, but few in numbers. Regarding the conservation status, 2 species belonged to ‘endangeredâ...
