St. Williams Nursery & Ecology Centre sells mixes of native grass and wildflower seed for roadside restoration. They typically recommend a nurse crop be planted alongside, both to provide better conditions for the native species. and to meet the request of customers that "green and stable" conditions are created quickly at newly disturbed sites. Roadsides are harsh environments, with high salinity, high nitrogen, high levels of disturbance and invasion by weeds. The proposed research will address their questions of which is the best nurse crop under roadside conditions, and which native species are best adapted to the roadside. In a farm field at St. Williams Nursery& Ecology Centre, the researcher will grow native plant mixes, varying the cover crop and adding different amounts of roadsalt and nitrogen. Both early growth, with measures of "green and stable", and later restoration success, with measures of biomass and native diversity, will be assessed. Comparing species performance in normal and roadside-type conditions will indicate which native species do best in roadside conditions. The results of this study will help St. Williams Nursery & Ecology Centre provide more appropriate recommendations for roadside restorations, which will increase the success of their restoration projects. Higher success rates will help in marketing their product, promoting higher seed sales. St. Williams Nursery& Ecology Centre and the researcher will publish the results in a report available to any organization engaging in roadside restoration projects that use native seed. This will benefit not only existing firms like SWENC and their clients, but will encourage the formation of new businesses, and the expansion of an industry which has tremendous potential to solve important natural resource problems in the province.

圣威廉姆斯苗圃和生态中心出售本地草和野花籽的混合物，用于路边修复。他们通常建议在旁边种植保护地作物，这两者都是为了给本土物种提供更好的条件。并满足客户要求，在新扰乱的场地迅速创造“绿色和稳定”的条件。 路边环境恶劣，高盐度、高氮、高干扰和杂草入侵。这项拟议的研究将解决他们的问题，即在路边条件下，哪种作物是最好的育苗作物，以及哪些本土物种最适合路边种植。在圣威廉姆斯苗圃和生态中心的一块农田里，研究人员将种植本地植物混合物，改变覆盖作物，并添加不同数量的路盐和氮肥。将对早期增长和恢复成功进行评估，包括“绿色和稳定”的衡量标准，以及生物量和本地多样性的衡量标准。比较物种在正常和路边类型条件下的表现，将表明哪些本地物种在路边条件下表现最好。 这项研究的结果将有助于圣威廉姆斯苗圃和生态中心为路边修复提供更合适的建议，这将增加其修复项目的成功。更高的成功率将有助于营销他们的产品，促进更高的种子销售。圣威廉姆斯苗圃和生态中心和研究人员将在一份报告中公布结果，任何从事路边修复项目的组织都可以使用本地种子。这不仅将使像SWENC这样的现有公司及其客户受益，还将鼓励形成新的业务，并促进一个具有解决该省重要自然资源问题的巨大潜力的行业的发展。
