Fig. 2: Factors affecting the choice of restoration sites.
From: Restoration cannot be scaled up globally to save reefs from loss and degradation
Partial dependency plots showing the marginal effects of the independent variables included in our model on the predicted probability of a site being the target of restoration. We report both the fitted functions (solid orange lines; n = 10,000) and fitted values (blue dots; n = 3,324). The rug plots on top of the panels show the density of observed values in the target independent variables. The percentage values in parentheses indicate the relative influence of each variable. Gravity was obtained from ref. 73 and represents the summed gravity of locations within a radius of 500 km from a target reef location, with individual gravity of each location within the radius computed as the ratio between the population of that location, and the squared distance (measured as travel time, in minutes) from the location and the target reef location. In the plot, we report the gravity values quoted by 1,000 to ease visualization of labels in the x axis. For the quantification of cumulative impacts, refer to ref. 71. Remoteness is reported as log-transformed travel time from a target reef location to the closest large human settlement, as in ref. 72. Bleaching alert levels refer to NOAA Coral Reef Watch data70 and we considered as ‘severe bleaching alert’ level events, those with alert levels I or II (Methods).
