ABSTRACT
Activities undertaken by householders in their gardens have huge potential to enhance city-wide biodiversity, but programs aimed at activating householders require an understanding of the factors encouraging or acting as barriers to the uptake of different kinds of activities. We provided 42 householders with two species-enhancing activities, selected from six possibilities, free-of-charge (to remove the barrier of initial cost). We collected socio-demographic data as well as information on knowledge of common urban species, pro-environmental behaviors and nature connectedness. We monitored ongoing engagement at two time points: 1 and 6 months. Characteristics of householders opting for different activities varied in terms of their degree of environmental engagement, their knowledge about common species, and the size of their gardens; e.g., bird feeders and bee planters were popular with people who did not know the names of common species and were not particularly engaged in pro-environmental activities respectively, whereas lizard habitat creation was attractive to people who were already engaged in wildlife gardening activities. Cost to continue with activities was a significant barrier for some people, but most householders were willing to practice relatively inexpensive activities in small spaces. Esthetics was an important factor to be considered when enhancing invertebrate habitat (e.g., bug hotels are more attractive than log piles, and planters for bees contain colorful flowers). A commonly cited barrier was lack of information about wildlife-friendly activities, despite much being available online. Most participants (85%) talked about their activities with others, potentially acting as influencers and shifting social norms.
