Points indicate a site at a given sampling time. Point colors indicate pre- (grey) and post-fire (green) plant communities and color shades indicate pre-fire spruce density. On panel a), the standard deviation ellipse is shown for each spruce density group, with the color shadings corresponding to pre-fire spruce density. Light grey lines link the same site before and after fire. On panel b), the dark grey arrows are overlays of species vectors significantly associated with plot position in the ordination space ( p ≤0.001). Arrow lengths were halved to facilitate visualization. Species codes can be found in S2 Table .
