According to https://www.riigiteataja.ee/en/eli/ee/510022014001/consolide there are exceptions to that rule and it's 2 years. I only have information available to me, but I do not think this is a hard set rule. What if they were cut down for housing?

https://www.globalforestwatch.org/dashboards/country/EST/ appears to suggest that within the past decade tree loss has doubled. While the population has been flat. So it does suggest that what you are saying is not happening.
