This study was conducted to assess the species composition and conservation status of pteridophytes in the
north-eastern portion of Mount Timolan Protected Landscape. The studyrevealed a total of 98 species comprising
52 genera from 21 families. Tectariaceae, Polypodiaceae and Dryopteridaceae was the most represent family with
Tectariaceae accounts the highest in terms of genera (9), followed by Polypodiaceae (8) and Dryopteridaceae (6). Whereas,
Polypodiaceae has the highest in terms of species record (16 spp.), tailed by Tectariaceae (14 spp.) and Dryopteridaceae
(10 spp.). Out of 98 recorded species, 95 were only identified up to species level. High number of accounted family
of terrestrial ferns and lycophytes are known as good ecological indicator taxa for habitat destruction and level of
human disturbances. In terms of status, eleven (11 spp.) are endemic to Philippines, eighteen (18 spp.) are economically
important species, nine (9 spp.) vulnerable, five (5 spp.) classified as other threatened species and two (2 spp.) are nonnative
species of ferns and lycophytes was recorded. Generally, the high species richness of pteridophytes found in the
north-eastern portion of Mount Timolan Protected Landscape are influenced by elevation gradient and susceptibility to
human disturbances. Less
