Quezon Protected Landscape (QPL) is a tropical rainforest situated at the southern Sierra Madre mountain range. However, it is subjected to anthropogenic pressure that poses threats to its flora and fauna. This study was conducted to describe the plant diversity, assess their ecological and conservation status, and to identify current anthropogenic threats in various vegetation types in QPL. Vegetation assessment was done using quadrat method established at different land use types wherein ninety 10×10 m nested plots were used for trees, 5×5 m subplots were used for herbs and shrubs, and 1×1 m subplots were used for grasses. The study documented a total of 328 species belonging to 84 families and 208 genera with 2,737 individuals. Species diversity is high as revealed by the values obtained from species diversity (H’) and species evenness (J’) indexes. Out of 172 tree species identified, the most important species are: Parashorea malaanonan (Blanco) Merr. in the regenerating and lowland evergreen dipterocarp forest; Diospyros pyrrhocarpa Miq. in the karst forest; Leucaena leucocephala (Lam.) de Wit in the secondary forest; and Cocos nucifera L. in the agroforest. Assessment of ecological status showed that out of 328 species, 213 (64.94%) are native, wherein 65 (19.8%) are endemic, and 115 (35.06%) are introduced. Forty-five species (13.72%) are threatened in which 25 of those are endemic in the Philippines. Overall, QPL has a wide array of plant species and threats such as the illegal extraction of natural resources, encroachment, cleanliness and presence of invasive alien species. So, it is recommended that protection and awareness campaign should be done for conservation and sustainability.

Despite extensive surveys conducted in the past, many remote areas in the Philippines remain unexplored and many species are unknown to science. The Mount Hamiguitan Range (MHR) is among these areas, containing large remaining forests tracts. In this study, we report new records of amphibians and reptiles from MHR and propose removing two species from the previously listed species from this mountain range. We used standardized techniques to sample populations of amphibians and reptiles in fragmented forests of Mt. Hamiguitan. Our survey resulted in 16 new records of species (four frogs, three lizards and nine snakes). Combining our results with previous studies, the known species diversity from the MHR is now increased to a total of 61 taxa. Our results highlight the underestimated diversity of herpetofauna of Mt. Hamiguitan, and we discuss the importance of repeated surveys for determining species occurrences and assessing their conservation status.

The present study was aimed at documenting species composition, utilization and conservation of plant species growing in home gardens of 10 residential areas of Coimbatore city, India. Household interviews and home garden surveys revealed that all the 109 plant species included in 60 families included have someeconomic uses or with ornamental significance. Higher number of species was herbs followed by shrubs, trees, climbers, succulent herbs, vines and sub-shrubs. The families viz., Asteraceae, Apocynaceae and Acanthaceae contributed higher number of plant species than the other families to the home gardens. Thespecies namely, Celosia cristata, Chrysanthemum odoratum and Ocimum basilicum have registered 50% frequency among the home gardens sampled which indicates that these species have distributed and maintained in comparatively higher number of home gardens. The home garden species are mainly under thecategories of vegetables, fruits, ornamentals, economic important species and medicinal. These results further report revealed that homegardens satisfy various household needs like food, ornamentals, medicines, building material, religious and ceremonial uses.

The aims of the present study were: 1) to perform a detailed mapping of the distribution of conservationally significant (endemic, vulnerable, endangered and protected) plant species in the group "Kanarata and Quarry Drenaka" of the protected area "Pobiti Kamani" for 2020 yr in GIS environment; 2) based on the overlap of the distribution sites of plant species, to determine the "hot spots" of plant biodiversity, access to which should be limited in order to protect them and at the same time to identify areas with no or low concentration of conservationally important species in order to trace and mark the tourist paths in the protected area. In order to investigate the distribution of six plant communities, a detailed GIS mapping was performed. As a result of the study, detailed distribution maps of investigated species communities in Central Group were drawn. Special attention is paid to the zones where two or more communities were overlapped. The identification of the areas with concentration of conservation-significant species and localization of "hot spots" is crucial for protection management of the group "Kanarata and Quarry Drenaka" of the protected area "Pobiti Kamani". The model of "hot spots" and the model of overlapping are applicable and in combination with detailed distribution maps are fundamental for more successful protection and conservation. The suggested touristic zones with lack of conservation species can be used to trace and to construct environmentally friendly tourist trail and paths without destroying and harming the species, their habitats, and the aesthetic and recreational value of the landscapes.

This study serves as the first generation research on the rich yet not poorly known ferns and lycophyte species of the Mount Timolan Protected Landscape (MTPL). A total of 151 species from 62 genera and 24 families were recorded from December 2019-May 2019. Overall, the species of MTPL respectively holds 14%, 40% and 71% of the recorded total species, genera and families of ferns and lycophytes in the Philippines. The most represented families in terms of the number of genera is Polypodiaceae (10 spp.), whereas, the most represented genera in terms of the number of species were Selaginella (11 spp.). The results of the study showed that Mount Timolan Protected Landscape harbours number of some endemic species (17 spp.), critically endangered species (1 spp.), endangered species (3 spp.), vulnerable species (5 spp.), threatened, non-native species and economically important species (25 spp.). Based on conservation and ecological status of assessed ferns and lycophyte species, it is likely to strongly suggest to set species-specific conservation management strategy to protect the threatened species. However, additional studies and thorough field explorations should also be done to conduct a re-inventory on the pteridophyte species in order to arrive a more scientific results to establish a real profile of the ferns and lycophyte species of Mount Timolan Protected Landscape.

Abstract. Biag RA, Alejandro GJD. Diversity, distribution, and conservation status of Rubiaceae species in Peñablanca Protected Landscape and Seascape, Luzon, Philippines. Biodiversitas 22: 3627-3636. Peñablanca Protected Landscape and Seascape (PPLS) is the largest protected area (PA) in the province of Cagayan, Luzon, Philippines. As part of the Sierra Madre Mountain Range and being contiguous with the Northern Sierra Madre Natural Park, there is no doubt that this PA would display species endemism and richness. Hence, botanical surveys through purposive sampling in seven barangays/districts were conducted in the PPLS to determine the species diversity and distribution of Rubiaceae. This study also aims to identify the endemic species and determine their conservation status. Forty-two species of Rubiaceae belonging to 19 genera and 13 tribes were documented in the current study. The most species-rich tribes are Spermacoceae (9 sp.), followed by Psychotrieae (7 sp.), Pavetteae (6 sp.), Naucleae (5 sp.), Ixoreae (4 sp.), Aleisantheae (2 sp.), Mussaendeae (2 sp.), and Vanguerieae (2 sp.). The rest of the tribes, i.e., Augusteae, Coffeeae, Gardenieae, Knoxieae, and Morindeae, are represented by a single species. Minanga, Nabbabalayan and Sisim harbor the most species. Results show that 19 Philippine endemic species are thriving in the PPLS. Of these, four are threatened species; one is near threatened, three being least concern, two as data deficient, and the rest were not evaluated.

Kuswanda W, Sunandar AD. 2019. Analysis of land use change and its relation to land potential and elephant habitat at Besitang Watershed, North Sumatra, Indonesia. Biodiversitas 20: 350-358. Land use change from forest into plantation at a watershed could be detrimental both for humans and wildlife. This study was aimed to analyze land use change and its impact on the habitat potential of Sumatran elephant (Elephas maximus sumatranus Temminck, 1857) in the upstream of Besitang Watershed located at Gunung Leuser National Park (GLNP), North Sumatra, Indonesia. The study was conducted from April to November 2015. Data collection was made through land cover map analysis, ground check and vegetation analysis using strip transect method. Land use change was analyzed using ArcView 3.2 software, species diversity was calculated using Shannon-Weiner formula and community evenness indices. Based on map delineation, total extent of Besitang Watershed is about 95,428 hectares. The analysis results showed that, in the past 25 years, about 15,989 hectares of land was changed from forests and farms to monoculture plantations. These changes have caused conflicts and threatened elephant population. As many as 168 species of plants were identified during vegetation analysis in the three study locations, namely Bukit Mas primary forest (88 species), Sekundur mixed secondary forest (91 species) and Halaban secondary forest (68 species). Average Importance Value Index (IVI) was below 40% which indicates that there are no dominant plant species. Tree density was between 360 and 497,5 individual/ha, sapling density was between 2,640 and 4,680 individual/ha, and density of seedling and understory plants was between 27,750 and 38,500 individual/ha. Species diversity index for each plant growth stage was relatively high (H’>3) and the similarity of plant species across locations was generally low (IS = <50%). Analysis of the correlation between land cover differences and habitat features showed statistically significant effects on species density and frequency. The highest effect of land cover change is on species density with the correlation reaching 94.5%. Forests in GLNP will be able to regenerate naturally to reach a stable state if there is no more land clearing to raise plantations.

The Philippines has approximately 1,100 species of lycophytes and ferns, and this represents approximately 9% of the worldwide fern flora. Botanical explorations and local documentations continue to expand the list. Local documentations increase our knowledge on species distribution and conservation status, which are essential in biodiversity conservation. This paper reports on a survey of the pteridophytes of Adams, Ilocos Norte, one of the remaining floristic sites in Luzon Island, Philippines. A series of floristic surveys conducted at selected sites in Adams recorded and vouchered 47 species, 34 genera and 21 families of pteridophytes. Among all these pteridophytes, six are threatened Philippine plant species. These are Platycerium coronarium, Ceratopteris thalictroides, Tectaria psomiocarpa, Psilotum nudum, Blechnum egregium, and Angiopteris evecta. This study contributes to the baseline data on Philippine pteridophytes especially on their distribution, and can serve as reference for biodiversity conservation and restoration efforts as ferns may help in the stabilization of degraded lands and facilitation in plant communities.

The historical information about natural vegetation of Lumbini is not clearly known. Modern day human colonization around Mayadevi temple could have been intensified after Khadga Samsher's visit to Lumbini in 1896, followed by the eradication of Malaria in the Tarai of Nepal around the 1950s. The dense human settlements around the Mayadevi temple (place where Buddha was born) was gradually shifted outside the area of Lumbini Development Trust (LDT) (16 x 4 km2 area), and the area was planted with a huge number of plant species. Hence, the forest within LDT is essentially a secondary forest without a scientific method of forest management (only plantation), as a result some species were not able to get naturally established and disappeared gradually. Studies indicated that there were around 354 species of plants species in LDT (Siwakoti, 2008) however, a recent vegetation survey (Tiwari, 1919) recorded only about 250 species including 39 tree species and other herbs and shrubs (the data is being produced, and needs second round survey to confirm). Some very common plant species have not been found from the region, indicating the heavy anthropogenic pressure including construction activities, grazing, fire, and plantation of trees without knowing microhabitat have taken the toll, and also by the encroachment of alien and invasive plant species both in terrestrial and aquatic environment. It is quite important to update the biodiversity, study regeneration of plant and animal species and management of invasive species in order to restore the natural ecosystems of Lumbini to develop it as both a sacred pilgrimage site and nature reserve. Ecosystem conservation and reintroduction at LDT could be done by following the strong reliance of Gautam Buddha's teaching about nature and life.

The Impact

Aim: Drastic changes in fire regimes are altering plant communities, inspiring ecologists to better understand the relationship between fire and plant species diversity. We examined the impact of a 2011 megafire on woody plant species diversity in an arid mountain range in southern Arizona, USA. We tested recent fire-diversity hypotheses by addressing the impact of the fire severity, fire variability, historic fire regimes, and topography on diversity. Location: Chiricahua National Monument, Chiricahua Mountains, Arizona. USA., part of the Sky Islands of the US-Mexico borderlands. Taxon: Woody plant species. Methods: We sampled woody plant diversity in 138 plots before (2002-2003) and after (2017-2018) the 2011 Horseshoe Two Megafire in three vegetation types and across fire severity and topographic gradients. We calculated gamma, beta, and alpha diversity and examined changes over time in burned vs. unburned plots and the shapes of the relationships of diversity with fire severity and topography. Results: Alpha species richness declined and beta and gamma diversity increased in burned but not unburned plots. Fire-induced enhancement of gamma diversity was confined to low fire severity plots. Alpha diversity did not exhibit a clear continuous relationship with fire severity. Beta diversity was enhanced by fire severity variation among plots and increased with fire severity up to very high diversity, where it declined slightly. Main Conclusions: The results reject the intermediate disturbance hypothesis for alpha diversity but weakly support it for gamma diversity. Spatial variation in fire severity promoted variation among plant assemblages, supporting the pyrodiversity hypothesis. Long-term drought probably amplified fire-driven diversity changes. Despite the apparent benign impact of the fire on diversity, the replacement of two large conifer species with shrubs signals the potential loss of functional diversity, emphasizing the importance of intervention to direct the transition to a novel vegetation mosaic.

UDK: 581.55(497.6) The ecosystems of the class Festuco-Brometea in Bosnia and Herzegovina play an important role in the overall biological diversity. They are distinguished by a large number of vegetation units, as well as by significant number of rare, endemic or relict plant species. The study area, Prečko polje, covers 1.27  at 1100 m a.s.l., and takes place in the heart of mountain complex Treskavica-Visočica-Bjelašnica. We analised thermophylous meadows of Prečko polje after method of phytocoenological relevé. The class Festuco-Brometea in study area is being differentiated into the alliances Xerobromion erecti (with suballiance Fumano-Scabiosenion leucophyllae) and Mesobromion erecti (with suballiance Eu-Mesobromenion). In general, thermophylous meadows are characterized by high degree of species diversity. Moreover, within thermophylous meadows of Prečko polje we have identified nine species which are considered to have certain conservation status, according to the national and/or international legislation. Our study has shown that investigated area should be considered as potential Natura 2000 site for it is inhabited by a significant number of rare and/or endangered orchid species.
