The negative impacts of urbanization on biodiversity are well known, and the use of native vegetation in private gardens and streetscapes have been shown to improve the species richness and abundance of native wildlife, thereby improving the biodiversity of the local area. This study poses the question of whether the general public is interested in planting native species, to determine whether a cultural shift in garden planting style is feasible. A total of 3707 questionnaires relating to nature in the backyard were delivered to residents in metropolitan Melbourne, Australia with 417 responses received (11.2% response rate). The results indicate that the public perception of the aesthetic appeal of native gardens is fairly positive and that Melbournians have considerable interest in planting native species in residential gardens and that a large number would like wildlife in their yards. The paper concludes that there is scope to encourage the use of native plants in residential landscaping.

If wildlife gardening programs wish to maximize their contribution to the biodiversity of their area, they need to be recruiting individuals who would not have undertaken wildlife activities of their own accord. This study sought to assess which program features equate to the most success in recruiting previously unengaged members. Providing site assessments and native/indigenous plants or vouchers to members were features shown to increase the likelihood of recruiting individuals who were not planning on creating a wildlife garden; however, these are not currently recruiting unengaged participants on a large scale and there is a need to develop other strategies to attract more previously unengaged individuals to the wildlife gardening cause.

The notion of designing with change constitutes a fundamental and foundational theoretical premise for much of what constitutes landscape architecture, notably through engagement with ecology, particularly since the work of Ian McHarg in the 1960s and his key text Design with Nature. However, while most if not all texts in landscape architecture would cite this engagement of change theoretically, few go any further than citation, and when they do their methods seem fixated on utilising empirical, quantitative scientific tools for doing so, rather than the tools of design, in an architectural sense, as implied by the name of the discipline, landscape architecture.

Abstract The enemy release hypothesis predicts that native herbivores will either prefer or cause more damage to native than introduced plant species. We tested this using preference and performance experiments in the laboratory and surveys of leaf damage caused by the magpie moth Nyctemera amica on a co-occuring native and introduced species of fireweed (Senecio) in eastern Australia. In the laboratory, ovipositing females and feeding larvae preferred the native S. pinnatifolius over the introduced S. madagascariensis. Larvae performed equally well on foliage of S. pinnatifolius and S. madagascariensis: pupal weights did not differ between insects reared on the two species, but growth rates were significantly faster on S. pinnatifolius. In the field, foliage damage was significantly greater on native S. pinnatifolius than introduced S. madagascariensis. These results support the enemy release hypothesis, and suggest that the failure of native consumers to switch to introduced species contributes to their invasive success. Both plant species experienced reduced, rather than increased, levels of herbivory when growing in mixed populations, as opposed to pure stands in the field; thus, there was no evidence that apparent competition occurred.
