Description

The dataset represents the count data of Odonates, which comprise Dragonflies (Anisoptera) and Damselflies (Zygoptera) found in Sikkim and Darjeeling Hills in West Bengal, India, collectively called the Kchangchendzonga Landscape. Sailendra Dewan collected the data between 2019 and 2020. The dataset is the consolidated data of counts conducted along a transect 200 meters Long and 2 meters wide. Transect count was made along the rivulets, springs, and artificial water channel constructed for irrigation.

Title	Biodiversity of Sikkim and Darjeeling
Study Area Description	Khangchendzonga Landscape, which encompasses the state of Sikkim and the districts of Darjeeling Himalaya (Darjeeling and Kalimpong) in the state of West Bengal (26.49 N to 28.12 N and 87.99 E to 88.79 E) is a part of the the Eastern-Himalayan region of the Himalaya biodiversity hotspot (Mittermeier et al., 2011). The region falls under the Warm pre-humid Agro-Ecological Zone (AEZ), and has been recognized as one of the agro-biodiversity hotspots of India. This AEZ is characterised by high precipitation (2,000 - 4,000 mm), lesser potential evapotranspiration (<1,000 mm) and longer growing seasons (>210 days). The elevation within the region varies from less than 50 meters in the foothills of Darjeeling to the towering height of 8,586 meters, represented by Mt. Khangchendzonga.

Sampling Methods

Adult odonates were sampled using the transect count method. Permanent line transects of 200m length and 5m width were laid in different land use types.

Study Extent	The sampling was conducted in the Khangchendzonga Landscape (Figure 1) , which encompasses the state of Sikkim and the districts of Darjeeling Himalaya (Darjeeling and Kalimpong) in the state of West Bengal (26.49 N to 28.12 N and 87.99 E to 88.79 E) The region is a part of the the Eastern-Himalayan region of the Himalaya biodiversity hotspot (Mittermeier et al., 2011). The region falls under the Warm pre-humid Agro-Ecological Zone (AEZ), and has been recognized as one of the agro-biodiversity hotspots of India. This AEZ is characterised by high precipitation (2,000 - 4,000 mm), lesser potential evapotranspiration (<1,000 mm) and longer growing seasons (>210 days). The elevation within the region varies from les than 50 meters in the foothills of Darjeeling to the towering height of 8,586 meters, represented by Mt. Khangchendzonga.
Quality Control	The odonates which remained unidentified in the field were photographed and later identified with the help of official portal of odonates of India (Joshi et al., 2019) and available literatures (Fraser, 1933, 1934 & 1936; Subramanian, 2005; Subramanian and Babu, 2017).

Method step description:

These transects were laid along artificial rivulets, water channels and paddy pools in the agricultural landscape. A slow and steady pace was maintained during the transect walk and all the individuals of odonates found within the 5m band on both sides of the transect were recorded along with identification details. Sampling was carried out between 09:00 and 14:00 hours during calm and sunny days because most odonates are active and the probability of encounter was high during this time.
