A ''special region'' on Mars for the purposes of [[Planetary protection]] is a region classified by COSPAR where terrestrial organisms are likely to propagate, or interpreted to have a high potential for existence of
(A special region is considered to be "... a region within which terrestrial organisms are likely to propagate, or a region which is interpreted to have a high potential for the existence of extant Martian life forms. Given current understanding, this applies to regions where liquid water is present or may occur." (Reference: COSPAR 2002 & 2005, NASA, 2005))"''}}</ref>. . Based on current understanding, this includes any region with a high enough temperature for Earth organisms to propagate (above -18°C), and with water in a form accessible to them (water activity higher than 0.6) {{refn|name=special_region_def|(see section 7.1.1.
