植物的生物多样性受到水、养分和阳光等有限资源的影响。然而，在城市环境中，例如住宅庭院，有限的资源还可能包括花在庭院护理上的时间和金钱等社会因素。为了研究这些宝贵的人力资源在决定植物群落结构和多样性方面所发挥的作用，我们调查了巴尔的摩市和巴尔的摩县（马里兰州）12个社区的房主及其庭院，共访问了96处住宅。我们根据居民的收入中位数（代表金钱）和生命阶段（代表时间）来选择社区，这些数据由ESRI的Tapestry数据集确定[老年人（>65岁，最有可能退休，有更多的空闲时间）与年轻人（
Plant biodiversity is affected by limiting resources such as water, nutrients, and sunlight. In urban settings, such as residential yards, however, limiting resources may also include the social factors of time and money spent on yard care. To examine the role that these precious human resources play in determining plant community structure and diversity, we surveyed homeowners and their yards in 12 neighborhoods across Baltimore City and Baltimore County, Maryland, visiting a total of 96 residential properties. We chose neighborhoods based on residents' median income (a proxy for money) and lifestage (a proxy for time) as determined by ESRI's Tapestry dataset [older (>65 and most likely retired with more free time) versus younger (
