Wildfires decrease the local-scale ecosystem spatial variability of Pinus canariensis forests during the first two decades post fire

The spatial variability (i.e. heterogeneity) of environmental variables determines a wide range of ecosystem features and plays a key role in regulating key ecosystem services. Wildfires are among the most significant natural disturbances that forests face, but our knowledge about their effect on ec...
