Direct answer

Wildfire risk area is a defined term in the International Fire Code (IFC) 2009, in Definitions. The code's own words are: “Land that is covered with grass, grain, brush or forest, whether privately or publicly owned, which is so situated or is of such inaccessible location that a fire originating upon it would present an abnormally difficultjob of suppression or would result in great or unusual damage through fire or such areas designated by the fire …” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 3 chapters of this corpus, most often in General Requirements (IFC 2009), Scope and Administration (IFC 2009), Definitions (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.
