This dataset contains the effect of stress and herbivory on the establishment of alternate provenances of a foundation tree species. This data relates to plant fitness and could be used for more broader studies in this area. We established a common garden experiment within a 238 ha restoration site owned and managed by the South Australian Water Corporation (SA Water), near the township of Clarendon (-35.0882°S, 138.6236°E). We grew ca.1500 seedlings sourced from one local and two non-local provenances of Eucalyptus leucoxylon to test whether local provenancing was appropriate. The three provenances spanned an aridity gradient, with the local provenance sourced from the most mesic area and the distant provenance sourced from the most arid. We explored the effect of provenance on four fitness proxies after 15 months, including survival, above-ground height, susceptibility to insect herbivory, and pathogen related stress.

Purpose
The data set are from a project that forms one component of the author's PhD thesis where they explored the relationship of provenance-to-site distance of a core restoration species in temperate Australia (i.e. a Mediterranean biome). The PhD focuses on promoting durable restoration plantings. The author explores the relationship of provenance-to-site distance, through common gardens and reciprocal transplant experiments. The author is also developing new monitoring tools incorporating next generation sequencing of the soil microbiome that will be used for restoration metrics and adaptive management interventions.
Lineage
1) Apical height: We scored aboveground height in cm for each plant with a graduated telescopic surveyors stave (Alumi Staff Pty. Ltd). Height was recorded as the vertical distance between the ground and the most distal photosynthetic tissue of each plant.
2) Invertebrate herbivory: The presence of (herbivory=1) was scored as present when ca. >5% of the entire foliage showed signs of herbivory, ca. <5% herbivory=0.
3) Pathogen related stress: Stress =1) was scored if leaf browning and leaf fall were evident or leaf blight or rust was observed on the plant, (no stress=0) was scored when no obvious signs of pathogens were evident on the plant.
