Study Design and Installation 



Plots used in the study were in a randomized block design with three replications, 

 Each replication consisted of nine different treatments plus a control: 



1. Control 



2. Seed (grass) straw mulch, erosion net, fertilizer 



3. Seed (ponderosa pine), straw mulch, erosion net, fertilizer 



4. Seed (ponderosa pine), straw mulch, erosion net 



5. Plant (ponderosa pine), 1.5 by 1.5-foot spacing, straw mulch, erosion net, 

 fertilizer. 



6. Plant (ponderosa pine), 1.5 by 1.5- foot spacing, straw mulch, erosion net 



7. Plant (ponderosa pine), 2.5 by 2.5-foot spacing, straw mulch, erosion net, 

 fertilizer 



8. Plant (ponderosa pine), 2.5 by 2. 5- foot spacing, straw mulch, erosion net
