This indicator is developed from a model that combines aerial mapping of the Island with data from the planning process. The term green space combines two formal land use categories: land under cultivation; and, natural environment. The latter includes woodlands, dunes, grassland, cliffs and shrub. This indicator divides the total amount of green space by Jersey's total land mass, excluding inland water (e.g. ponds, streams and reservoirs) and inter-tidal areas.

In 2022, 70.6% of the Island consisted of land under cultivation or natural habitat. This figure does not include man-made green space such as private gardens, public parks, sports fields, and golf courses, which account for another 14% of Jersey's land mass.
