Flocks tend to arrive from Siberia in early October and it is not the first time the site has been fenced off for them.
A spokesperson from Southsea Coastal Scheme added: “Last year we successfully used this area for the geese, with our highest number spotted in the refuge at one time coming in at 380.
“Throughout the wintering period we recorded 12 three-figure counts of geese, four of which were in excess of 300.”
Southsea Common is officially recognised as a Solent Wader and Brent Goose Strategy site.
The refuge will be monitored throughout the winter and the fencing will be removed as the geese begin their long journey back to Siberia for the summer.
