A total of 19,618 sh[ub seedlings were planted in 2 concentrated planting <br />areas in 1997, see drawing 5297 -4A. Table 97.4r lists planting areas, approximate <br />acreages, species composition of each area, and the total numbers planted by species for <br />each area. All plant materials were one-year-old containerized nursery stock developed <br />from bitterbrus h, chokecherry, Ga mbel oak, serviceberr y, snowberry, and Woods rose seed <br />collected from the Seneca II mine site.
