Visit SILT Properties: Back Details of Okanagan River Restoration In 2004, SILT acquired four adjacent properties along the Okanagan River that were integral to the multi-million dollar Okanagan River Restoration Initiative (ORRI). SILT retained ownership of these properties until December, 2009, when The Nature Trust of B.C. took over ownership. Today, the property is open to the general public and includes a trail network. YOU CAN HELP SILT is a registered non-profit society and tax receipts can be issued for donations of cash or property or bequests from estates, so consider making a tax-deductible donation of money or land or including the society in your will, in order to further our common objectives of conserving habitat for the Okanagan’s wildlife. Learn more about how you can make a difference. SILT has no paid staff, so all donations go directly to fulfilling the society’s mandate of purchasing and restoring habitat for fish and wildlife. Instead it is operated by a volunteer board of directors.
