Bubalus arnee Forage under Threat: an Assessment of Koshi Tappu Wildlife Reserve, Nepal

Open access
·2019·International Journal of Research Studies in Zoology

Abstract

Wild water buffalo (Bubalus arnee) are categorized as endangered on the IUCN Red list, with global population of less than 4000 individuals distributed over less than 20,000 km 2 in Nepal, India, Srilanka, Bhutan, Cambodia, Myanmar and Thailand.In Nepal Bubalus arnee is locally called Arna or Jungali bhainshi is larger and heavier than domestic buffalo weighing from 800 to 1200 kg.They are probably grazers by preference, feeding mainly on grasses, but also eat herbs, fruits, barks and browse trees and shrubs.There were 432 Bubalus arnee in Koshi Tappu Wildlife Reserve in 2016.Threats were identified through literature review and verified during the sample plots survey, questionnaire and expert views.50 foraging plots were set where fresh dung of Bubalus arnee existed and recorded in survey form.Six potential threats were identified viz flooding, domestic cattle grazing, collection of forest products, invasive plant species, forest fire and shrinking habitat.Flooding and domestic cattle were highly significant threats to the foraging plants.Measures to control threats will perhaps help to protect the human wildlife conflict in the area.

TL;DR

This study identifies six potential threats to forage plants preferred by endangered wild water buffalo (*Bubalus arnee*) in Koshi Tappu Wildlife Reserve, Nepal. Flooding and domestic cattle grazing were the most significant threats reported.

Key findings

  • Six potential threats were identified: flooding, domestic livestock grazing, collection of forest products, invasive plant species, forest fire, and shrinking habitat.
  • Flooding was recorded in all 50 foraging plots and accepted by all 50 questionnaire respondents; domestic cattle grazing was recorded in 40 plots but accepted by only 23 respondents, while forest product collection was recorded in 28 plots and accepted by 21 respondents.
  • Invasive species were recorded in 23 of 50 plots and accepted by 23 respondents; *Mikania micrantha* was recorded as consumed by *Bubalus arnee* in 10 plots. Forest fire was recorded in 12 plots.
  • Shrinking habitat was accepted by 17 respondents and linked to population growth from 63 individuals in 1976 to 432 in 2016, reducing space from 2.78 km² to 0.41 km² per individual.

Methods

  • The study was conducted in Koshi Tappu Wildlife Reserve, Nepal, on the Saptakoshi river floodplain.
  • Fifty 5 m × 5 m foraging plots were set where fresh *Bubalus arnee* dung was directly observed; a survey format recorded plot data, cattle presence, habitat, GPS coordinates, and existing plants.
  • Potential threats were identified from plot surveys (n=50), a questionnaire with local community members (n=50), literature review, and expert views; data were analyzed using SPSS version 20.

Limitations

  • The paper states that there was a lack of information directly suggesting threats to plant species, so the research depended on other relevant threats such as threats to *Bubalus arnee*, KTWR, and biodiversity.
  • The paper notes that accurate numbers of purebred *Bubalus arnee* in KTWR remain unclear because censuses were based on morphology rather than genetic study.
  • Evident from the text: threat identification relied partly on cause-and-effect reasoning and secondary information, and plot survey results and questionnaire responses disagreed for domestic cattle grazing and forest product collection.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Conflicting conservation status for Bubalus arnee

    Minor

    The paper describes Bubalus arnee as endangered on the IUCN Red List, but later calls it critically endangered.

  • Invasive-species responses did not increase over plot observations

    Minor

    The text says invasive species increased in respondents' responses, but reports the same count-23-for respondents and surveyed plots.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
