There has been a 99% drop in visitor numbers to some of Coillte's forests around the country since restrictions on movement were introduced last month.
Portumna Forest Park in Galway, the Devil's Glen in Wicklow and Ards Forest Park in Donegal experienced the sharpest declines amid the ongoing coronavirus measures.
Meanwhile, the number of people visiting Coillte forests in Dublin has fallen by 78%.
Around 720 people visited forests at Kilmashogue, Kiltipper and Rathmichael between March 28th and April 3rd.
That compared with around 3,200 visitors recorded the previous week.
Across all 23 of the forests, a total 6,800 people visited between March 28th and April 3rd - compared to 36,250 the previous week.
Imelda Hurley, Chief Executive of Coillte, thanked the public following the guidelines.
She said: "We understand this is a challenging time, but by observing the Covid-19 related Government and HSE advice, you are helping to save countless lives.
"The significant reduction in footfall recorded across our recreational forests is a clear signal that the public are taking their responsibility seriously and protecting our most vulnerable communities."
Meanwhile, Wicklow County Council says a number of facilities in the county will remain closed over the Easter weekend.
The upper car park at Glendalough, Brittas Bay car parks north and south and the cliff walk between Bray and Greystones are among the temporary closures.
The council says it regrets the closures, but they've made the decision to "support national public restriction on movement and physical distancing requirements".
