47 Figure S2. First year population success (a-c) calculated as summed biomass of all individuals
48 within a plot), percent overwinter survival (d-f) and second year population success (g-i) in
49 relation to aspect and elevation in neighbor removal sub-plots. For graphing purposes we present
50 site means to better illustrate patterns, but analyses were conducted on plot data. A significant
51 positive relationship between population success and elevation and/or a significantly higher
52 population success on north-facing aspects indicates that relocated species do better in cooler
53 environments. Vertical dashed lines represent current upper elevation range limit for the three
54 target species; North-facing aspects (N: white symbols, black dashed line) south-facing aspect
55 (S: grey symbols, grey line) and non-aspect sites (X: black symbols); Black solid lines represent
56 regressions when all three aspects (N, S, X) are combined.

Figure S3. Mean species responses at early life stages (% germination and logRR at germination)
59 on north-facing (white circles, dashed lines) south-facing (grey circles, grey line) and non-aspect
60 (black circles) sites along the elevation gradient. Here we used the same analysis (GLMM:
61 aspect, elevation, and the interaction between aspect and elevation, site as a random factor) as we
62 did with population success. Horkelia and Phacelia germination were higher on north aspects >
63 700m. Arabis responses were not strongly influenced by aspect, but were influenced by elevation
64 with little germination or survival and lower biomass at higher elevations. Neighbors had a
65 positive effect on the germination of Phacelia at higher elevations. Neighbors had no effect on
66 germination of Horkelia or Arabis . Black vertical dashed lines show upper elevational range
67 limit for each species. For graphing purposes we present site means to better illustrate patterns,
68 but analyses were conducted on plot data.
