Increasing loss of mature boreal forests around protected areas with red-listed forest species

Ecological Processes

Table 1 Mean values (± standard error) in the proportion of forests clear-cut in 2000–2019 in the buffer zones around RFPAs (PAs where red-listed forest species were observed) and their significance between the different forest vegetation zones
