2. Possible Impact of Habitat Extension on the Management
of Blackbuck (Antelope cervicapra) in Hirapur Phanta of Suklaphanta
National Park
Project start and end date:
Started from mid of November 2016 and ended within April 2017
4. 1. INTRODUCTION
Blackbuck (Antelope cervicapra) locally known as Krishnarsar, is an elegant, gazelle-like animal,
regarded as the most handsome member of the ‘Bovidae’ family and is a medium size
antelope.
It has been endemic to South Asian Sub-continent (Nepal, India and Pakistan).
In Nepal, scattered population of blackbuck occurred in Banke, Bardiya and Kanchanpur
districts of western Nepal as late as 1960s.
Now it is restricted in Khairapur of Bardiya district (281 BB) and Kanchanpur district (50 BB)of
western Nepal.
In Kanchanpur, Re-introduced Blackbucks are kept in predator proof fenced enclosure of 17 ha.
at Hirapur phanta of younegst SuNP.
5. Introduction..
The blackbuck inhabits low growing grassy plains and thinly
forested areas., while they avoid densely forested and hilly
areas.
They are primarily grazers and some time browse leaves of
trees, fruit and shrub.
They shows sexual dimorphism where characteristics of
body coloration and horns are used to differentiate
male (buck) and female (doe).
6. 2. RESEARCH OBJECTIVES
General Objective:
To assess the possible impact on the conservation and management of
Blackbuck population from habitat extension and their release to a natural
habitat condition of Hirapur Phanta.
Specific Objective:
• To assess the habitat suitability of Hirapur Phanta for blackbuck
population.
• To investigate possible threats to the management of blackbucks in
Hirapur Phanta after their release from the enclosure
7. 3. RESEARCH METHODOLOGY:
3.1 Study Area
Study Site:
Hirapur Phanta
Total Area =150
hectare
Predator proof
Enclosure area =17
hectare
8. 3.2 Data Collections
3.2.1 Primary data
Reconnaissance Survey
Vegetation inventory
House Hold Survey
Discussion with Key Informants
9. Sampling Design
For Vegetation composition ( RD, RF,RC)
Quadrate sampling along transect lines was carried.
- 14 transect lines were laid through out Hirapur Phanta
- East west direction
- Transect line to transect line distance= 200 m. (Jnawali,1995)
- Altogether 53 sampling plots were taken (40 sampling plot outside while 13 inside the enclosure)
- Quadrate size= 1m × 1m. ( For ground vegetation)
- Sampling plot to sampling plot distance along transect line = 150 m. (Khatri,1993)
For Household Survey
• 29 HHs ( 10%) out of 283 HHs were selected randomly from Simalphanta village which was
adjacent to eastern part of the Hirapur Phanta.

13. 4.1.2 Vegetation composition
• Altogether 16 grass species were recorded during the month of February.
• Among them less preferable Siru has the highest relative cover followed by highly preferable
Dubo and moderately preferable Kuro respectively both inside and outside of the enclosure.
• Dubo has the highest relative frequency and IVI both inside and outside of the enclosure.
• Unwanted species like Tapre, Besarma were relatively abundant outside the enclosure.
14. • Comparison between Relative cover of some
Blackbuck preferable grass species found inside and
outside of enclosure in Hirapur Phanta.
Comparison between Relative cover of less preferable
and unwanted grass species found inside and outside of
enclosure in Hirapur Phanta.
17. 4.2 Objective 2: Threats to the management of Blackbuck habitat

4.2.1 Possible tendency of meeting Blackbuck and Livestock
18. 4.2.2 Possibility of Disease Transmitting
• Hirapur Phanta was grazed by more than 450 cattle each
day.
• Common diseases of cattle in the study were Foot and
Mouth Disease i.e. Khoret followed by Rinderpest,
Pneumonia, Worm infestation, Tila, Diphtheria, Scabies
(Luto rog) and Diarrhea.
19. 4.2.3 Possible Threats due to Predation
• Figure 6: Possible Threats due to
Predators in Hirapur Phanta
21. 4.2.5 Invasion of Grassland by Unwanted Species
• Outside of enclosure, unwanted species of grasses and shrubs like
Tapre, Gandhe jhar and Besarma (Ipomoea fistula) were invading
BB preferable grasses.
• Besarma (Ipomoea fistula) was also poisonous for BB.
22. 5. CONCLUSION
• BB preferable grass species are comparatively abundant inside the enclosure
while less preferable and unwanted species are abundant outside the enclosure.
• Predation by Leopard, Jackal, Wild boar, Tiger and attack of Stray dogs are major
possible threats to Blackbuck in the Hirapur phanta.
• Higher possibility of transmission of FMD Khoret and Rinderpest disease from
livestock when they share same grazing fallow and water source.
• Poaching is not serious problem for Blackbuck in Hirapur Phanta at the moment
• Habitat management issues like invasion by unwanted species and heavy grazing
are challenging threats.
23. 6. RECOMMENDATION
• Unwanted invasive species should be controlled and eradicated.
• Conduct Vaccination camp for cattle.
• BB desirable cereal should be cultivated on certain parts of the Phanta cereal
crops should be cultivated on certain parts of the Phanta to provide
supplementary food during food deficit period.
• sterilization of the female dogs.
• Sufficient number of artificial water holes should be constructed and their timely
maintenance
• Range improvement activities like ploughing, controlled fire burning,grass cutting
and other pre release operation should be carried out.
• Should prepare a national conservation action plan for the long term survival and
management of Blackbuck in Nepal.
