Birds of Loharghat Forest Range, Assam

Study Extent

August 2021 to June 2023

Sampling

Transect Data collection Analysis

Method steps

1. Transect: A total of 78 km2 was covered across 22 transects for 368 hours. In Barduar, a 39.6 km2 transect was walked in the Barduar Reserve Forest between 0630 h and 1300 h, and 38.4 km2 in the Mayang Reserve Forest between 0530 h and 1200 h. Of all the transects, 15 were surveyed three times, and seven were surveyed twice. Each time, 2–3 observers were present, ensuring data reliability. Data collection & Analysis: Data collection sheets and e-bird were used to record observations, including date, time, weather conditions, species, flock size, coordinates, record type (vocalisations/sightings), and habitat type. The occurrence status of bird species is determined by the proportion of days with sightings from the research area throughout the length of the survey period: Very Common (VC) >50%, Common (C) = 25–50%, Uncommon (UC) = 5–25%, and Rare (R) = 1–5%.

Loharghat Forest Range, within the Indo-Burma biodiversity hotspot, features diverse habitats like wetlands, scrublands, grasslands, tropical and deciduous forests. Chandubi, a vital tectonic wetland in the landscape, is designated as Important Bird Area (2003) and Key Biodiversity Area (2005) but remains largely unexplored. This study aims to establish a baseline database of avifaunal assemblages from the Loharghat Forest Range in Kamrup District, Assam, which includes the Mayang Reserved Forest and Barduar Reserved Forest.
