“…The number of community treatments for each focal species was derived from the fact that (1) one species mixture (with E. nitens ) was only represented for E. pauciflora and (2) the single community plot comprising the mixed planting of the focal species constituted a community treatment for both species. The E. nitens / E. pauciflora treatment was included as these species had been the focus of previous research in the Midlands region (Close et al ). The Cassinia aculeata treatment was represented in two community plots per replicate due to suitable plants for another planned treatment being unavailable at the time of planting.…”

The stability of species and provenance performance across diverse environments is a major issue in restoration, particularly for assisted migration and climate‐adjusted provenancing strategies. This study examines how differences in species and provenance performance are affected by plant community composition in a dry sclerophyll forest restoration experiment. Five indices were measured over 6 years post‐establishment to evaluate the relative performance of community composition using 10 provenances of two focal eucalypts (Eucalyptus pauciflora and Eucalyptus tenuiramis) under six community treatments for E. pauciflora and five for E. tenuiramis. Community treatments varied according to the species planted as the immediate neighbor to the focal species, and included same species, same genus, or one of three different genera. Significant species and provenance differences were observed for all measured performance indices, with no evidence of interaction effects with community treatments. E. tenuiramis was more susceptible to insects and frost, and had poorer establishment but greater growth of the survivors than E. pauciflora. Generally, nonlocal provenances were more susceptible to insect herbivory and frost damage and had higher mortality than local provenances. At this early life‐stage there was no evidence that co‐planted species affected the relative performance of focal species or provenances, arguing transfer functions are likely stable across different planted communities. While species and provenance performance was not affected by community context, focal species differed in their response to upslope migration and any climate‐adjusted provenancing may require staged transfers to avoid maladaptation under contemporary growing conditions.

“…First, species may be planted into a more benign environment (in terms of irradiance levels and temperature extremes; von Arx et al 2013). Second, the already established plants may provide a positive 'nurse' plant effect (e.g., Close et al 2010) via either physical (e.g., spines) or chemical (e.g., toxins) protection from herbivory or by simply reducing the visibility of newly established plants to herbivores (Smit et al 2007). However, while this strategy might reduce herbivory, beneficial effects from nurse plant are not consistently observed in restoration studies since increased competition resulting from the close proximity of neighbours can outweigh facilitation effects (Gómez-Aparicio et al 2004;Caldeira et al 2014;Poulos et al 2014): facilitation is most likely to be observed with increasing abiotic stress.…”

Factors affecting the long-term survival and growth of planted understorey species in reintroductions and restoration are poorly known. Seven understorey species were planted in jarrah forest restored after bauxite mining in the Southwest of Western Australia to test the effects of the competitive environment (both over-and understorey) and herbivory by large mammals on survival and growth over a 16-year period. Differences in the overstorey environment were achieved by planting the study species into restored sites differing in age (0, 1, 4 and 10 years of age). The understorey competitive environment was manipulated by removing other understorey species at the time of planting. Reducing both herbivory (using plant guards) and competition with other understorey plants significantly increased survival, spread and height growth of the study species. Planting into different ages of restored site significantly affected plant responses: survival and growth were maximal in either newly restored (year 0) or the oldest (10 years of age) sites. Across species, survival decreased to *50 % after 2 years, but thereafter mortality was low. These data demonstrate survival and spread of planted species over a 16-year period indicating that planting nursery-raised plants can be a viable strategy for establishing long-term persistent plant populations in both newly restored and older restored sites.

“…(subsp. pauciflora) is an important restoration species used in plantings throughout Tasmania and mainland Australia (Close et al, 2005(Close et al, , 2010. These species are from different Eucalyptus subgenera (E. globulus from subgenus Symphyomyrtus, E. pauciflora from subgenus Eucalyptus) that differ qualitatively in their chemical profiles.…”

Stability of Plant Defensive Traits Among Populations in Two Eucalyptus Species Under Elevated Carbon Dioxide

Plant secondary metabolites (PSMs) mediate a wide range of ecological interactions. Investigating the effect of environment on PSM production is important for our understanding of how plants will adapt to large scale environmental change, and the extended effects on communities and ecosystems. We explored the production of PSMs under elevated atmospheric carbon dioxide ([CO(2)]) in the species rich, ecologically and commercially important genus Eucalyptus. Seedlings from multiple Eucalyptus globulus and E. pauciflora populations were grown in common glasshouse gardens under elevated or ambient [CO(2)]. Variation in primary and secondary chemistry was determined as a function of genotype and treatment. There were clear population differences in PSM expression in each species. Elevated [CO(2)] did not affect concentrations of individual PSMs, total phenolics, condensed tannins or the total oil yield, and there was no population by [CO(2)] treatment interaction for any traits. Multivariate analysis revealed similar results with significant variation in concentrations of E. pauciflora oil components between populations. A [CO(2)] treatment effect was detected within populations but no interactions were found between elevated [CO(2)] and population. These eucalypt seedlings appear to be largely unresponsive to elevated [CO(2)], indicating stronger genetic than environmental (elevated [CO(2)]) control of expression of PSMs.
