Marchant practices in the areas of water, natural resource, environmental, and real property law.  He was raised on a cattle ranch in southern Idaho where he developed an early appreciation for the use and development of natural resources.  His clients include ranchers and farmers whom he has assisted with various natural resource and water right issues involving the Idaho Department of Water Resources, the Bureau of Land Management, and the United States Forest Service in matters primarily related to the administration of water rights, the National Environmental Policy Act, and the Endangered Species Act.  Mr. Marchant has extensive experience utilizing water right transfers to change elements of water rights to meet the evolving needs of his clients.  He has also assisted clients with obtaining water bank approval for temporary water uses.  In addition, he has appeared before the Snake River Basin Adjudication Court to assist his clients with the adjudication of their water rights.  He has also assisted clients with ditch and canal disputes, and other land use and property matters.
