    (Wildlife Institute of India, Dehradun, 2018) Rajpur, V.; Johnson, J.A.; Srivastava, Ajay
    The aim of the report is to give an overview regarding the areas in Askot landscape which are in need for conservation in terms of aquatic habitat. This study is a part of the project Biodiversity Conservation and Rural Livelihood Improvement (BCRLIP) in Askot landscape. This report deals with the assessment of aquatic resources of Askot landscape with reference to human footprints available there. The focus is mainly on the assessment of fish density and people dependency on fishes along with the caused disturbances. People were-highly dependent on stream Rautis which is located at lower altitude of the landscape. Several human disturbances were identified in the landscape which is electrofishing, bleaching, water diversion, dynamiting, regulated water, sand mining, roads, stream crossings and waste discharge. Riparian quality was assessed in the streams of Askot landscape and found out Dhauli coming under the category F which shows low quality because of changes in the habitat. This provides the health and ecological status of all streams. On the basis of indicator criteria two indicator species was narrowed down as Schizothorax richardsonii and Naziritor chelynoides. So habitat requirement for both the species was studied and found out different requirement for substrate as boulders for Schizothorax and sand, silt for Naziritor. Further monitoring protocol is made for managing the Askot landscape in terms of aquatic fauna.
