Attributes of property parcel owners are hypothesized to impact land management outcomes, because different types of owners are likely to have different capacities and motivations for land stewardship. We used emerging data resources to examine how owner type relates to the prevalence of overgrown vegetation in Toledo, Ohio, and Trenton, New Jersey, USA. Overgrown vegetation was characterized at the property parcel scale using data from comprehensive parcel surveys in each city, and owner attributes were categorized using local property tax databases. We categorized owners into types (e.g., individuals, investors, nonprofits), classified owners as local or non-local, and determined whether or not parcels were owner-occupied. Then we tested for differences in rates of overgrown vegetation across owner types using inferential statistics including chi-squared tests and autologistic regression. Individual owners had lower rates of overgrown vegetation than other owner types. Neighborhood context was also important, as overgrown lawns were more prevalent in high-vacancy areas. Among parcels owned by individuals, overgrown vegetation was less prevalent when the owner resided locally, and when the property was owner-occupied. This study advances our understanding of social-ecological outcomes in US shrinking cities by exploring how land ownership is related to vegetation management in ways that can dictate whether vegetation is serving as an amenity to the community. These findings may help promote desirable social-ecological outcomes and lead to more equitable futures in high-vacancy neighborhoods. Specifically, our results point to more equitable vegetation outcomes when parcels are owned by individuals, and particularly owners who reside on-site or locally.

假设财产地块所有者的属性会影响土地管理结果，因为不同类型的所有者可能具有不同的土地管理能力和动机。我们使用新兴数据资源来研究所有者类型如何与美国俄亥俄州托莱多和新泽西州特伦顿的杂草丛生的植被流行率相关。使用来自每个城市综合地块调查的数据，在地块范围内对过度生长的植被进行了表征，并使用当地财产税数据库对所有者属性进行了分类。我们将业主分为不同类型（例如，个人、投资者、非营利组织），将业主分为本地或非本地，并确定地块是否为业主自用。然后，我们使用包括卡方检验和自逻辑回归在内的推论统计来测试不同所有者类型之间杂草丛生率的差异。与其他类型的所有者相比，个人所有者的植被过度生长率较低。邻里环境也很重要，因为杂草丛生的草坪在高空置率地区更为普遍。在个人拥有的地块中，当业主居住在当地时，以及当业主自住时，杂草丛生的植被不太普遍。本研究通过探索土地所有权如何与植被管理相关，从而决定植被是否为社区提供便利设施，从而加深了我们对美国收缩城市的社会生态结果的理解。这些发现可能有助于促进理想的社会生态成果，并在高空置率社区带来更公平的未来。具体而言，我们的结果表明，当地块归个人所有时，尤其是居住在现场或当地的业主拥有时，植被结果会更加公平。
