Simultaneously, tree stature may change from tall to small abruptly or gradually, while trees might also get crippled into krummholz (German for “crooked wood”). Tree cover may stop suddenly to form a discrete boundary between closed forest and alpine vegetation, or the transition may be more diffuse, dominated by single trees or by tree islands. But this transition between forest and alpine vegetation is not the same at every treeline: the spatial configuration of the trees and the change in tree size and shape can differ considerably between treelines in different mountain ranges, or even within them. Thus, one could say that a substantial amount of man and women power has been allocated for this paper – and for a good reason.Īnyone who has ever walked through a treeline must have noticed that it is not actually a line at all, but a transition zone, i.e. Since then the authors have been brainstorming ideas around and beyond this paper, especially in three face-to-face meeting (pre-COVID time obviously): twice at iDiv, Leipzig (Germany), and once in New Zealand.
The idea for this paper was born during a workshop in the Pyrenees, in Jaca (Spain), September 2017.
Bader.Īs treeline researchers, we have been fascinated by treeline spatial patterns and the processes behind these for quite some time.
