What is "reseeding"

Usage examples of "reseeding".

Ever hear of a disease organism that simply killed the cells around it, without spreading, or reseeding itself at a distant site?

All of the others, from Donald at Henley to Gervase at Maidenhead, from Thomas near Reading to Lucy near Marlow, from Ferdinand in Wokingham to Serena in Bracknell, and even Vivien in Twyford and Alicia near Windsor, all of them seemed to have put down roots in a ring round the parent house like thistledown blown on the wind and reseeding.

Trees were a renewable resource, and the logging companies had been pretty good about reseeding the land, but the fact remained that they were cutting a lot faster than the trees were growing.
