City Flora #1 - The Lawn
Among ecologists and environmentalists, lawns have a well-deserved reputation as "green deserts." This is because, despite being defined by an extensive cover of green plants, they are not very biologically diverse landscapes. Across the world, lawns tend to be sown not only with the same grass species, but also with the same varieties, limiting both genetic and species diversity within and between lawns (Ignatieva and Ahrne 2013). What's more, only a handful of wild plant species are able to elbow their way into growing among the grasses and these are often the same across wide geographic areas (Ignatieva and Steward 2009; Wheeler et al. 2017). This lack of plant diversity in turn limits the insect communities that can find suitable habitat and forage in a lawn. Meanwhile, all the management that is needed to maintain homogenous acres of grass contribute significantly to other environmental problems, such water pollution and scarcity (Robbins et al. 2001; Milesi et al. 2...
