The suggestions outlined in the “plant species” section represent a set of species that could possibly grow at your site, based on predictive models that correlate on-the-ground observations (in this case the presence of different plant species) with environmental data (things like the local climate, elevation and the type of soil present) to estimate where a given species might occur. The environmental variables that inform the models we’ve included are typically relatively low resolution (often 1km2 or more), meaning that they can provide predictions at broader scales, but cannot capture very local-scale variation. Our species lists may therefore not be perfectly accurate at the scale of your backyard (for example), which might be drier than average for the area, have less fertile soil, etc. – this is a great example of why global data needs to be paired with on the ground knowledge and experience! We always recommend consulting with local experts before starting any new restoration projects.
