Urban residents impressions of Invasive Alien Plants in South African towns

Invasive alien species are considered a major contributor to biodiversity loss. Yet many are favoured for particular ecosystem services that they provide. This is often so in urban environments experiencing rapid environmental and social change and land transformation. Public support is viewed as critical for invasive alien species prevention and management. Furthermore, it is assumed that local citizens are more likely to be willing and ready to engage if they are informed about the costs and benefits associated with invasive alien species. However, the use of, and attitudes towards, invasive alien species in urban areas is poorly understood, especially regarding urban gardens under private ownership and control. This lack of understanding is likely to compromise potential management interventions.
Here we report on a survey of 240 people across 12 small towns in the Eastern Cape province of South Africa to determine their knowledge and perceptions regarding woody invasive alien plants..., In each of the 12 study towns, 20 residential households were randomly selected using Google Earth. To randomly select households in each town, each household was identified on Google Earth, assigned a unique number, and then a random sample drawn, using Microsoft Excel. Randomly selected households were then approached for face-to-face  interviewers and in situations where there was nobody available or willing in a randomly selected household, the next available household was sampled. Permission was asked from the owner to survey their garden and list any woody Invasive Alien Plants (IAP) present. Within the selected households, a willing adult respondent was interviewed to gather information on knowledge, perceptions and willingness to control woody IAPs. The interviews were conducted either in IsiXhosa, English, Afrikaans, or according to the respondent’s preference. If the preference was another language, then a translator was hired to assist and recorded the responses which were la..., , # Data from: Urban residents impressions of Invasive Alien Plants in South African towns

The data set provides data from the interview sample of urban respondents in 12 towns in South Africa, with 20 interviews per town, providing a total of 240 samples. Thereafter, the columns of data follow the questions posed in the interview questionnaire provided in supplementary materials. Data codes are provided. Not all respondents answered every question of the survey; thus blank responses are indicated using n/a. The number of indirect identifiers was reduced and limited to three (town, age, gender).

Column A: name of town.
Column B: Had the respondent heard of Invasive Alien Plants (IAP) before (1=yes; 2=no).
Column C: if a respondent answered yes to the previous question, then what was the source the information?

Column D: self-rating of the extent of the their knowledge about IAP (1=none; 2=poor; 3=neutra...

外来入侵物种（Invasive Alien Species）被视为生物多样性丧失的主要诱因之一。然而，诸多外来入侵物种却因其所提供的特定生态系统服务而受到青睐。在经历快速环境与社会变革、土地转型的城市环境中，这种现象尤为普遍。公众支持被视作外来入侵物种防控与管理的关键环节。此外，学界普遍假设：若当地居民了解外来入侵物种相关的成本与收益，将更愿意且有能力参与相关行动。然而，当前学界对城市区域中外来入侵物种的使用情况及公众态度的认知仍较为匮乏，尤其是针对私人所有与管控的城市花园这一场景。这种认知不足可能会削弱潜在管理干预措施的实施效果。

本研究针对南非东开普省12个小镇的240名居民开展了一项调查，以了解居民对木本外来入侵植物的认知与看法……在12个研究小镇中，每个小镇随机选取20户住宅家庭，选取方式基于Google Earth：先在Google Earth上识别每户家庭并分配唯一编号，随后使用Microsoft Excel进行随机抽样。对抽中的家庭开展面对面访谈；若抽中家庭无人应答或不愿参与，则选取下一户符合条件的家庭。需先征得户主同意，方可对其花园开展调查并列出其中存在的木本外来入侵植物（Invasive Alien Plants, IAP）。在抽中的家庭中，招募愿意参与的成年受访者进行访谈，收集其对外来入侵植物的认知、态度及防控意愿相关信息。访谈可使用IsiXhosa（科萨语）、英语、Afrikaans（南非荷兰语），或根据受访者偏好选择其他语言；若受访者偏好其他语言，则聘请翻译协助并记录访谈内容，后续内容因原文截断未完整呈现……

本数据集包含南非12个城镇的城市受访者访谈样本数据，每个城镇完成20份访谈，总计240份有效样本。数据列对应附录材料中访谈问卷的提问项，同时附带数据编码。并非所有受访者均回答了问卷的全部问题，因此空白响应以n/a标注。间接标识符的数量已缩减至三项，分别为城镇、年龄与性别。

列A：城镇名称
列B：受访者是否曾听闻外来入侵植物（IAP）（1=是；2=否）
列C：若受访者在上一题选择“是”，则填写其获取相关信息的渠道
列D：受访者对自身外来入侵植物知识掌握程度的自评（1=完全不了解；2=较差；3=一般……，原文后续内容截断未完整呈现）
