Here are some web links that have interesting information about the Puget Sound prairies:

1)          http://www.southsoundprairies.org/documents/Indigenousburning.pdf [1]

2)          http://www.davidsonia.org/files/17_2_dunwiddie.pdf [2]

3)          http://www.wnps.org/plant_lists/counties/thurston/documents/MimaMounds.pdf [3]

4)          http://www.wnps.org/plant_lists/counties/thurston/documents/ThurstonCounty.doc [4]

I have been skeptical about moving in more plants as the weather is getting warm.
