Résumé :	Identifying and protecting microhabitats with conservation value is becoming a high priority for conservationists under projected climate change. Information on the buffering effects of microhabitats and its major drivers is a prerequisite to implementing effective conservation. We collected hourly temperature data from 70 alpine-subalpine sites nested within 9 boulder field clusters in an area measuring approximately 60 km x 30 km in New South Wales, Australia, over a period of more than 2 years. We studied the thermal buffering effect of the boulder fields and investigated the factors driving the effect using multilevel (i.e., sampling points nested within boulder field clusters) regression modeling. We found remarkable seasonal and spatial variations in the thermal buffering effect of boulder fields. Boulder fields buffered the surface temperature maxima by 2.91 degrees C at a depth of
