Extended Data Fig. 3: Exposure level to the unprotected matrix for each biogeographic region.
(A) Box plots of the exposure level to the unprotected matrix for each biogeographic region. Each sample corresponds to a 1 km spatial resolution cell (n = 15,459,063). Box plots show the median (centre line), the first and third quartiles (box limits), and the 95% confidence intervals of the distributions (whiskers). (B) Cumulative growth curves of the total area protected for “distance to the unprotected matrix” for each biogeographic region. Dots indicate the contact zone, that is the protected cover fraction <2 km from PA edges.
