2006年，在枫树沼泽边缘附近建造新的水处理拱顶，为绿色屋顶栖息地进行了实验的机会。
为了为绿色屋顶为本土昆虫和地面嵌套提供“栖息地岛屿”，他们应该种植原生物种，但是众所周知，东部北美植物可以在苛刻的屋顶条件下存活。
The goals for the WCBG green roof are to evaluate native plants for potential use on roofs, and to sustain a diverse community of native plants without supplemental water or nutrients in standard green roof growing conditions (e.g. a maximum depth of 6” of a growing medium composed mostly of expanded shale). Of the 28 species originally planted in April 2006, all native to eastern North America, most individuals of all but one species survived the first two growing seasons, including the extended drought of late summer 2007, and some species are spreading (Fragaria Virginiana）或播种大量（Sedum Nevii.）。没有计划额外的种植。
植物每次春天监测。拉击毒品杂草被拉了，但没有应用其他管理。截至2007年秋季的屋顶持续存在的物种是杂草的混合物（草本流动的植物不是草，壮洲，匆忙），草，低生长灌木和蕨类植物，相当多样化的社区。屋顶上许多物种的个体也被种植在相邻的花园中，以比较在对比生长条件下的生长和生存。
