Later that year, he started a movement to help develop a National forest policy for the United States of America.

Due to symptoms of "Meniere's Symbole",[6] Graves resigned from his position as Chief Forester, completing his duties in 1920.

Both Henry Graves and George Cromie [Yale Forest School, 1911 and 1st Superintendent of Trees, City of New Haven, CT] provided technical forestry management assistance to George Dudley Seymour for the woodlands surrounding the Hale Homestead, which would become the Nathan Hale State Forest in 1946.

Graves was the third person to receive this SAF award for distinguished service to American forestry.

Clarence Korstian read a prepared statement by Gifford Pinchot in presenting the medal to Graves: "...I have the honor and the profound pleasure of presenting to you the Sir William Schlich memorial medal for distinguished service to American forestry.

The Henry Solon Graves Grove is located within Del Norte Coast Redwoods State Park.

A Leader of unusual ability in the profession of forestry in which he has rendered distinguished service to his country".
