    Priority areas for ecological assessment along samruddi corridor, Maharashtra, India: preliminary report
    (Wildlife Institute of India, Dehradun, 2019) WII
    Global conservation strategies depend strongly on the creation and strengthening of the protected area network. However, several protected areas are facing new challenges of development In their surroundings leading to habitat f fragmentation and species loss. Roads are essential transport infrastructure to support India's endeavors of fulfilling vital transportation needs across the country. In the last decade, negative impacts of road network has been significant. .Special attention. is therefore required to protect wildlife values like corridors and distribution ranges of wildlife species that overlay the alignment of the expressway. The task, therefore, is to foresee conservation beyond protected areas that undergo modification due to growing infrastructural development, which eventually exerts pressure on protected areas. Maharashtra State Road Development Corporation (MSRDC) has proposed to build a smart green expressway connecting Nagpur to Mumbai. The highway aims at strengthening the rural agriculture sector while enhancing mobility. Although, the proposed alignment does not cross through any existing protected areas nevertheless MSRDC has envisaged developing the road as wildlife friendly infrastructure aiming at conservation outside protected area network. The objective of this report is to assist MSRDC and Government of Maharashtra in addressing ecological concerns at an early stage of planning the highway for safeguarding wildlife values. The preliminary report by the Wildlife Institute of India provides a framework for the protection of wildlife along the proposed alignment (701 km) of Nagpur Mumbai expressway, Maharashtra, India. This report aims at developing a roadmap to assess and evaluate ecological implications of future road development in the landscape with special emphasis on wildlife corridor function. Relevant mitigation measures shall avoid these impacts (direct, indirect and cumulative) of road infrastructure on various wildlife taxa and their habitats within the three landscapes of Maharashtra. The consecutive assessments conducted post this report will provide a strategic mitigation plan to present and minimize impacts of the proposed expressway on ecological habitats and wildlife. The Nagpur-Mumbai expressway is planned to be the first of Its kind project, where mitigation measures for wildlife are planned before? the road is built. This report helps in identifying the Important wildlife habltats that may require further assessment to design appropriate mitigation structures

    Ecological assessment of sites designated for collection of sand and bouders from river beds of Uttarakhand : study report
    (Wildlife Institute of India, Dehradun, 2011) WII
    Economic development invariably requires resources. Extraction of resources from the environment involves changes in the state of the environment. Hence, our ability to integrate development and ecological integrity can help in making informed decisions without affecting the ecological values of the ecosystem. The Riverbed Materials (RBM) are renewable resource which are abundantly used as construction materials. RBMs are byproduct of the massive sediment load and deposition that the rivers carry along the course of its flow. In Uttarakhand, most rivers that run through bhabar tract are targeted for their rich deposition RBM ( sand and boulders). Uttarakhand Forest Development Corporation (UAFDC) has proposed extraction of RBM form different rivers in Uttarakhand. Under the direction of Ministry of Environment and Forest (MoEF), vide letter No.11-329/2010-FC, dated 16 November 2010 the Wildlife Institute of India has carried out a study to assess the impact of RBM collection in six rivers (Kosi, Dabka, Nihal, Gola, Sharda and Kiroda Nullah). Subsequently, vide its let No. 8- 80/93-FC (pt.), dated 26 November 2010 the Ministry of Environment and Forests, Government of India directed to add two more sites; viz. Tons and Yamuna Rivers at Kalsi and Rampur Mandi respectively in Chakrata Forest Division. The Terms of Reference (TOR) of the study are as under: 1. Assessment and identification of the adverse impacts, if any, of the collection of sand, boulder and other minor minerals on wildlife and its habitat; 2. Identification of the appropriate ameliorative measures to eliminate if possible, or minimize to the extent possible, the identified adverse impacts of the collection of minor minerals on wildlife and their habitat; 3. Identification/ delineation of the migratory corridors in and around the area proposed for collection of minor mineral; 4. Assessment and identification of the adverse impacts, if any, of the non-collection of sand, boulder and other minor minerals from the area identified as corridor on river geometry and soil erosion pattern along the adjoining river banks; and 5. development of an appropriate plan for management of the identified migratory corridors. Such plan inter-alia may include restriction on collection of minor minerals for major part of the year, with a provision of periodic accelerated collection (preferably during the period having least frequency of wildlife movement) to maintain river geometry.
