This is the first plant functional trait database for Nova Scotia, Canada. The data contained here were collected between 2016 and 2019 from locations around Halifax, Nova Scotia. The species selected for trait collection were chosen based on species inventories taken across Nova Scotian coastal barrens and from green roofs at Saint Mary's University. The purpose of the coastal barren trait data was to understand community assembly in this understudied ecosystem. The green roof inventory was included as coastal barren species are known to succeed on green roofs in Nova Scotia. The green roof trait data was used to answer questions surrounding coexistence and trait divergence, and community assembly and spatial heterogeneity. In total, this database contains 14,341 trait values from 203 species comprising 130 genera and 53 families. The majority of species are commonly found on coastal barrens (84 species), disturbed sites (48 species), and forests (27 species). Additionally, this database contains trait data for 30 species that have been successfully established (survival for >1 year) on green roofs in Nova Scotia and ruderal species that commonly colonize both green roofs and coastal barrens. This database contains 12 plant functional traits: leaf thickness (203 species), leaf area (203 species), specific leaf area (203 species), leaf dry matter content (203 species), plant height (203 species), canopy width (203 species), seed mass (79 species), seed shape (61 species), root radius (22 species), leaf phosphorus content (3 species), leaf nitrogen content (30 species), and leaf carbon content (30 species). The species in this database can be subdivided into 10 growth forms, with the majority of species characterized as forbs (75 species), shrubs (56 species), or graminoids (33 species). This data set is freely available for scientific use; when used in published analyses, this paper should be referred to as the data source.
这是加拿大新斯科舍省的第一个植物功能性状数据库。这里包含的的数据是在 2016 年至 2019 年间从哈利法克斯周边地区和圣玛丽大学的绿色屋顶收集的。用于性状收集的物种是根据在新斯科舍沿海荒地和圣玛丽大学绿色屋顶上进行的物种清单选择的。沿海荒地性状数据的目的是了解这个研究较少的生态系统中的群落组装。绿色屋顶清单包括在内，因为已知沿海荒地的物种在新斯科舍省的绿色屋顶上成功。绿色屋顶性状数据用于回答关于共存和性状分歧、群落组装和空间异质性的问题。该数据库共包含 203 个物种的 14341 个性状值，这些物种包含 130 属和 53 科。大多数物种常见于沿海荒地（84 种）、干扰地（48 种）和森林（27 种）。此外，该数据库还包含 30 种在新斯科舍省绿色屋顶上成功建立（存活时间超过 1 年）的物种和常见于绿色屋顶和沿海荒地的繁殖物种的性状数据。该数据库包含 12 种植物功能性状：叶片厚度（203 种）、叶面积（203 种）、比叶面积（203 种）、叶片干物质含量（203 种）、植物高度（203 种）、冠层宽度（203 种）、种子质量（79 种）、种子形状（61 种）、根半径（22 种）、叶片磷含量（3 种）、叶片氮含量（30 种）和叶片碳含量（30 种）。该数据库中的物种可细分为 10 种生长形式，其中大多数物种为草本植物（75 种）、灌木（56 种）或禾本科植物（33 种）。该数据集可供科学使用；在发表的分析中使用时，应将本文作为数据源。
