Summary - what did the authors do and why?

The authors studied the spatial regeneration patterns of ponderosa pine within large patches of high severity fire, specifically regeneration distribution and height from distance to unburned edge.

Publication findings:

Regeneration densities of ponderosa pine decreased with increasing distance to unburned edge. Next, ponderosa pine regeneration could be more strongly influenced by intraspecific facilitation than interspecific competition from dense sprouting species.

How do spatial and landscape patterns of fire relate to tree dispersal, regeneration, and establishment?

Regeneration densities of ponderosa pine decreased with increasing distance to unburned edge. Next, ponderosa pine regeneration could be more strongly influenced by intraspecific facilitation than interspecific competition from dense sprouting species.
