“…The spotted nutcracker (Nucifera caryocatactes) is responsible for spreading P. cembra seeds, with lots of seedlings found above the current tree limit at both OZ and GT. Up to 100,000 seeds are spread by each bird per year, and on average, six seeds are buried together, one reason, why P. cembra recruits in clusters (e.g., Tomback et al 1993;Müterthies 2002;Neuschulz et al 2018;Gugerli et al 2022). However, GPS bird tracking revealed that a great fraction of these seeds is also buried in places unsuitable for P. cembra (e.g., in dense spruce forests; Sorensen et al 2022).…”

“…So, it was difficult to separate temperature from land userelated tree abundance (Didier 2001;Gehrig-Fasel et al 2007;Ameztegui et al 2015;Shi et al 2022;He et al 2023). Although currently protected, both the OZ and GT sites are under browsing and grazing pressure (young cattle, deer, chamois, ibex; Gugerli et al 2022). Along our high slopes at OZ, it was hard to find trees that had not lost their terminal bud at least once during the past 10 years (2021 was a particularly "bad" winter with a lot of browsing damage).…”
