A supporting device is disclosed for the removable attachment thereof to a wooden object such as a tree trunk that avoids the insertion into the wooden object of a metallic fastener that could later damage machinery used while processing the wooden object. The supporting device includes a support plate having a first face and a second face and a first and a second edge. The support plate defines a plurality of apertures, each aperture of the plurality of apertures extending between the first and the second face of the support plate. A plurality of legs are provided with each leg having a first and a second extremity. Each leg threadably cooperates with a corresponding aperture of the plurality of apertures. A plurality of feet are provided with each foot being attached to a corresponding second extremity of each leg such that in use of the supporting device, the plurality of feet abut against the wooden object for supporting, stabilizing and spacing the support plate relative to the wooden object. The support plate further defines a first slot and a second slot spaced from the first slot with each of the slots extending from the first face to the second face. An elongate flexible strap has a first termination and a second termination such that in use of the supporting device, the flexible strap extends through the first slot and the second slot of the support plate. A tensioning fastener attached to the flexible strap includes a first portion secured to the first termination of the flexible strap. A second portion is attached to the flexible strap between the second termination of the flexible strap and the first portion of the tensioning fastener. The arrangement is such that in use of the supporting device, the flexible strap loops around the wooden object and the first portion of the tensioning fastener cooperates with the second portion of the tensioning fastener for selectively tensioning the flexible strap. The flexible strap extending between the first slot and the second slot of the support plate is disposed between the support plate and the wooden object.
