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.

开展和参与促进私人花园本地物种的活动

住户在花园中开展的活动具有增强全市生物多样性的巨大潜力，但旨在激活住户的计划需要了解鼓励或阻碍开展不同类型活动的因素。我们从六种可能性中免费为 42 位住户提供了两项物种增强活动（以消除初始成本的障碍）。我们收集了社会人口数据以及关于常见城市物种、环保行为和自然联系的知识的信息。我们在两个时间点监测持续参与：1 个月和 6 个月。选择不同活动的住户在环境参与程度、对常见物种的知识以及花园大小方面的特征各不相同；例如，喂鸟器和养蜂器分别受到不知道常见物种名称和不特别从事环保活动的人的欢迎，而蜥蜴栖息地的创造对已经从事野生动物园艺活动的人很有吸引力。继续活动的成本对某些人来说是一个重大障碍，但大多数住户愿意在小空间内进行相对便宜的活动。在改善无脊椎动物栖息地时，美学是一个需要考虑的重要因素（例如，虫子旅馆比木桩更有吸引力，蜜蜂的花盆里有五颜六色的花朵）。一个普遍提到的障碍是缺乏有关野生动物友好活动的信息，尽管网上有很多信息。大多数参与者 (85%) 与他人谈论他们的活动，
