Eucaliptes can use great amount of water and stabilise hydrologic regime ViA evapotranspiration, but at the some time will protect land from extreme dry.

Hello

Thank you for your response

In your opinion, is eucalyptus more harmful to the groundwater table or its benefits and use for the ecosystem?!

Eucalypts will certainly deplete groundwater due to their high water consumption therefore it depends on whether you're wanting to lower groundwater levels or increase them......... also in arid or semi-arid regions they will have an even greater impact on depletion
