"Warming hiat.s" occurred in t.e Alt.ySayan Mount.in Region, Siberia in c. 1997–2014.

During t.e hiat.s, EGC area increased in t.e highlands(>1000 m)(+30%), whereas at.low and middle elevat.ons(t.e EGC area decreased(-7%). t.e EGC area increase was observed on t.e rain-ward nort.west.slopes mainly. In highlands, EGC area increase mainly correlat.d wit. summer air t.mperat.re, whereas at.low and middle elevat.ons EGC area decrease correlat.d wit. drought.index SPEI and vapor pressure deficit.VPD).

t.e phenomenon of t.ee waves （hedges and ribbons） format.on wit.in t.e alpine ecot.ne in Alt.i Mount.ins and it. response t. observed air t.mperat.re increase was considered. At.t.e upper limit.of t.ee growt. Siberian pine （Pinus sibirica） forms hedges on windward slopes and ribbons on t.e leeward ones. Hedges were formed by prevailing winds and orient.d along winds direct.on. Ribbons were formed by snow blowing and accumulat.ng on t.e leeward slope and perpendicular t. t.e prevailing winds, as well as t. t.e elevat.on gradient. Hedges were always linked wit. microt.pography feat.res, whereas ribbons were not. t.ees are migrat.ng upward by waves and new ribbons and hedges are forming at.or near t.ee line, whereas at.lower elevat.ons ribbons and hedges are being t.ansformed int. dosed forest.. t.0}e series of high-resolut.on sat.llit. scenes （from 1968 t. 2OLO） indicat.d an upslope shift.in t.e posit.on ribbons averaged 155＋26 m （or 3-7 m yr^-1） and crown closure increased （about.35%-90%）. t.e hedges advance was limit.d by poor regenerat.on est.blishment.and was negligible. Regenerat.on wit.in t.e ribbon zone was approximat.ly 2.5 t.0}es （5060 vs 2120 ha^-1） higher t.en wit.in t.e hedges zone. During t.e last.four decades, Siberian pine in bot. hedges and ribbons st.ongly increased it. growt. increment. and recent.t.ee growt. rat. for 50 year-old t.ees was about.t.ice higher t.an t.ose recorded for similarly-aged t.ees at.t.e beginning of t.e 20^t. cent.ry.
