The next-generation of ESII is here! Ecosystem Intelligence (EI) is a comprehensive quantification platform for nature-based decisions.
| Survey Question | Landscaped Area: Lawn | |
| A lawn is a manicured grass area which is mostly planted (sod) or seeded grass. Lawns would be mowed on a regular basis (≥2 times /year). Responses shown assume well established and maintained lawn conditions with no other vegetation types present (i.e. no trees or shrubs). All attributes are subject to management objectives and design considerations. Highlighted responses require answers specific to each map unit condition (e.g. soil conditions, slope, water regime, etc.) because these conditions are unique to every map unit for this habitat type. | ||
