Nursery population and habitat maintenance services

Nursery population and habitat maintenance services are the ecosystem contributions necessary for sustaining populations of species that economic units ultimately use or enjoy either through the maintenance of habitats (e.g., for nurseries or migration) or the protection of natural gene pools. This service is an intermediate service and may input to a number of different final ecosystem services including biomass provision and recreation-related services.

Likely response	Effect of variability on services provision	Human action or natural variation	Timescale	Spatial Characteristics
			Short - Long term	Local - areas where terrestrial ecosystems are being used will be most impacted.
