Abstract: A method and apparatus for controlling human scent from hunters in tree stands. The apparatus in its preferred form is a portable tree stand in combination with a heat shield and a heater holder selectively attached to the bottom of the tree stand foot platform to define a plenum and a portable heater holder. In operation the heater, such as a propane heater, heats the air in the plenum which expands and rises like all warm air and carries with it the human scent which is then directed up past the body and away.
