Appendix 1 Variables Used in the Equal-stratified Sampling Design

The mean annual temperature and percentage of forest cover were each split into three classes by identifying the natural breaks in their distributions in ArcGIS (ESRI 2009). Bedrock types were reclassified qualitatively as granitic rocks, schistose rocks, and all other types that have a limited distribution in the area. The study area was then stratified by combining these classes to generate 27 strata, of which 23 were represented in the area. This stratification was performed using the ArcGIS Spatial Analyst extension (ESRI 2009).

Appendix 4 Results of Information-Theoretic-Based Model Selection Based on the Akaike Information Criterion for Total Species Richness (SR), C-strategists Richness (SRc), S-strategists Richness (SRs), and R-strategists Richness (SRr), Detailing Number of Model Parameters (k), Maximised Log-likelihood Function (logL), Adjusted Deviance Explained (adj.D2), the Small-sample Bias-corrected Form of Akaike’s Information Criterion AICc, Akaike Differences (∆i) and Akaike Weights (wi)

Note that the Akaike weights (wi) always sum up to 1.

Appendix 5 Pearson Correlation’s Value Between Observed and Predicted Values (10-folder cross validation); Model Averaging Coefficients, Linear and Polynomial Forms for Total Species Richness (SR), Competitor Species Richness (SRC), Stress-tolerant Species Richness (SRS) and Ruderal Species Richness (SRR)

Appendix 6 Patterns of Conflict Between Alien Invasive Plants and the Several Targeted Ecosystem Services: Type of Spatial Conflict (Detailing the Six Types of Potential Conflict Between the Ecosystem Service Value and Invasive Species Richness); Invasive Richness (Detailing the Class/es of Invasive Species Richness for the Six Types of Conflicts); ES Value (Representing the Classes of Ecosystem Service Value Mapped Considered in Each of the Six Types Of Conflicts)

The following columns summarize the values of the area (%) of the spatial conflicts, for each ecosystem service mapped (1. Water cycle; 2.Carbon sequestration; 3.Biodiversity/habitat protection; and 4. Wood production), and for each response variable (SR – total richness; SRC – C-strategists richness; SRS – S-strategists richness; and SRR – R strategists richness)
