The prime Greater One-horned Rhino's (Rhinoceros unicornis) habitats include a mosaic of grasses, oxbow lakes, Shorea robusta forests, and alluvial floodplains and the major habitat of this species is riverine grasslands dominated by Imperata cylindrical and riverine forests dominated by Trewia nudiflora. This study was mainly focused on the analysis of habitat suitability of Rhinoceros unicornis in Nawalparasi, Chitwan, and Parsa districts of Nepal. The secondary data such as bioclimatic and topographical variables were collected from relevant sources. Spatial data were processed using various tools of ArcGIS while the presence data were converted using Excel, and analysis was done with Maxent. The results showed that approximately 75.17% (53.32 sq. km) of suitable area is occupied by Chitwan National Park. Similarly, Barandabhar Corridor Forest occupies 7.38% (18.89 sq. km) of the suitable area of the landscape. While, there is no area suitable for Greater One-horned Rhinoceros in Parsa National Park. Among Land Use Land Cover (LULC), the riverbed was found to be the most important variable. Invasion of invasive plants was found to be the most frequent disturbance factor followed by human disturbances and forest fires. Though grassland management is an important part of habitat management, it is highly recommended that the management of waterholes should be done. Protected Area manager should conduct localised habitat suitability assessment once the area is found suitable at the landscape level and further field verification should be done. Invasive plant control measures and alternatives to meet the forest product demand should be promoted.

Predicted declines in suitable habitat for greater one‐horned rhinoceros (Rhinoceros unicornis) under future climate and land use change scenarios

Rapidly changing climate is likely to modify the spatial distribution of both flora and fauna. Land use change continues to alter the availability and quality of habitat and further intensifies the effects of climate change on wildlife species. We used an ensemble modeling approach to predict changes in habitat suitability for an iconic wildlife species, greater one‐horned rhinoceros due to the combined effects of climate and land use changes. We compiled an extensive database on current rhinoceros distribution and selected nine ecologically meaningful environmental variables for developing ensemble models of habitat suitability using ten different species distribution modeling algorithms in the BIOMOD2 R package; and we did this under current climatic conditions and then projected them onto two possible climate change scenarios (SSP1‐2.6 and SSP5‐8.5) and two different time frames (2050 and 2070). Out of ten algorithms, random forest performed the best, and five environmental varia...

Identifying and prioritising climate change adaptation actions for greater one-horned rhinoceros (Rhinoceros unicornis) conservation in Nepal

Ganesh Pant
Climate change has started impacting species, ecosystems, genetic diversity within species, and ecological interactions and is thus a serious threat to conserving biodiversity globally. In the absence of adequate adaptation measures, biodiversity may continue to decline, and many species will possibly become extinct. Given that global temperature continues to increase, climate change adaptation has emerged as an overarching framework for conservation planning. We identified both ongoing and probable climate change adaptation actions for greater one-horned rhinoceros conservation in Nepal through a combination of literature review, key informant surveys (n = 53), focus group discussions (n = 37) and expert consultation (n = 9), and prioritised the identified adaptation actions through stakeholder consultation (n = 17). The majority of key informants (>80%) reported that climate change has been impacting rhinoceros, and more than 65% of them believe that rhinoceros habitat suitabil...

Determinants of abundance and habitat association of mammals in Barandabhar Corridor Forest, Chitwan, Nepal

Barandabhar Corridor Forest (BCF), the biologically functional corridor, is surrounded by the large human settlements that exploit the corridor where large mammals such as tigers, leopards and their prey such as ungulates, primates, and rhinoceros occur. This study aimed to evaluate major determinants that affect the distribution of large mammals in BCF, Chitwan, Nepal that connects the biologically significant Chitwan National Park with the Mahabharat range. The status and distribution of large mammals along the habitat and disturbance gradients were determined by using 29 line transects (mean length = 4.59 ± 0.38 km) that covered a linear distance of 133.13 km. The chital were the most abundant mammals (density per km2 (D) = 8.9095 ± 1.4570 and encounter rate per km (ER) = 1.49) followed by rhesus monkey (D = 38.896 ± 16.013, ER = 0.28), wild boar (D = 14.814 ± 3.57, ER = 0.62), northern red muntjac (D = 9.6566 ± 2.9514, ER = 0.62) and sambar (D = 5.392 ± 2.319, ER = 0.38).

Identification of suitable habitat for Swamp Deer Rucervus duvaucelii duvaucelii (Mammalia: Artiodactyla: Cervidae) in Chitwan National Park, Nepal

Swamp Deer is a globally threatened large-sized deer species confined within small patches of the Indian subcontinent. Historically, Swamp Deer occurred in Chitwan National Park, Nepal but was extirpated in the 1960s primarily due to widespread hunting. We assessed the habitat suitability at present for the Swamp Deer in Chitwan National Park using multi-criteria analysis in GIS and vegetation assessment using frequency, dominance, and cover. Within the 952.63km2 area of the national park, the habitat suitability analysis identified 14.57km2 as highly suitable, 134.87km2 as suitable, and 803.19km2 as moderate to least suitable area. Most of the national park’s grassland is suitable for Swamp Deer. Grassland is dominated by Saccharum spp.; Imperata cylindrica is the most widely distributed grass species followed by Saccharum spp., Narenga porphyrocoma, and Apluda mutica. Grass species of the Poaceae family are the most preferred species by Swamp Deer, which are found within sho...

Seasonal variations in food plant preferences of reintroduced Rhinos Rhinoceros unicornis (Mammalia: Perrissodactyla: Rhinocerotidae) in Manas National Park, Assam, India

The food preferences of translocated Rhinos in Manas National Park were studied to find out variations in seasonal and annual preferences. A total of 139 plants species belonging to 39 families were observed to be consumed as food. On an average, grasses (n=33) contributed 24% of Rhino food, aquatic plants (n=23) 16.5%, shrubs (n=11) 7.5%, herbs (n = 31) 22.3% trees (n=26) 18.7%, creepers (n=3) 2.1% and agricultural crops (n=12) 8.6%. Among the grasses, throughout the year Arundo donax, Cynodon dactylon, Imperata cylindrica, Saccharum elephantinus and Saccharum spontaneum were the maximum preferred species. Rhinos were observed to browse shrubs and tree twigs during the winter season and browsing was found to be very limited during the monsoon due to the abundance of young grass. Various anthropogenic pressures such as unregulated grassland burning, cattle grazing, invasions of Bombax ceiba and shrubs like Chromolaena odorata, Leea asiatica and herbs like Ageratum conyzoides ha...
