Water flow regulation services

Baseline flow maintenance services are the ecosystem contributions to the regulation of river flows and groundwater and lake water tables. They are derived from the ability of ecosystems to absorb and store water, and gradually release water during dry seasons or periods through evapotranspiration and hence secure a regular flow of water. This may be recorded as a final or intermediate ecosystem service. Peak flow mitigation services are the ecosystem contributions to the regulation of river flows and groundwater and lake water tables. They are derived from the ability of ecosystems to absorb and store water, and hence mitigate the effects of flood and other extreme water-related events. Peak flow mitigation services will be supplied together with river flood mitigation services in providing the benefit of flood protection. This is a final ecosystem service.

Respuesta probable	Efecto sobre la variabilidad	Acción humana o variación natural	Escala de tiempo	Características espaciales
			Long term	Local to regional - the areas where wildfires occur
			Short term	Local to regional - impacts can be in the immediate vicinity but also can affect neighboring regions/countries

Respuesta probable	Efecto sobre la variabilidad	Acción humana o variación natural	Escala de tiempo	Características espaciales
			Short - Long term	Local to global - local areas and regions differ in their emission of greenhouse gas emissions, however this form of pollution acts on a global scale
			Short - Long term	Local to global - emissions often occur locally, but atmospheric lifetimes are long enough for them to be transported across continents
			Short - Long term	Local to global - impacts can be observed ranging from local to global level

Respuesta probable	Efecto sobre la variabilidad	Acción humana o variación natural	Escala de tiempo	Características espaciales
			Mid - Long term	Local - impacts can have local cooling and warming atmospheric effect
			Long term	Local to global - climate is changing on a global level, with some regions experiencing more rapid and/or intensive changes in weather than others
			Short - Long term	Regional to global - impacts are mostly observed at large regional levels but can also be global

Respuesta probable	Efecto sobre la variabilidad	Acción humana o variación natural	Escala de tiempo	Características espaciales
			Short - Long term	Local - areas where terrestrial ecosystems are being used will be most impacted.
			Short - Long term	Local - areas where invasive species occur can act as fire agents that affecting the local area

Respuesta probable	Efecto sobre la variabilidad	Acción humana o variación natural	Escala de tiempo	Características espaciales
			Mid - Long term	Local - impacts can negatively affect migratory species
			Short - Long term	Local to regional - impacts can be local but also further downstream.
