Vegetation Data Summary

Stem counts were conducted within four strategically placed 10-meter by 10-meter plots. The plots
were located based on a representative sample of the entire area of disturbance. They are scattered
throughout the Project Site in order to cover the majority of the habitat variations. Vegetation Plots #1,
#2 and #4 are related to stream and buffer mitigation credit and occur within the 50-foot buffer of the
channel. Vegetation Plot #3 is outside of the 50-foot zone and falls under either buffer mitigation credit
or Nutrient Offset Nitrogen Reduction credit.

A total of two supplemental plantings were conducted at the Brock site. In March 2013, an additional
840 containerized hardwood trees were installed due to low vigor. In March 2014, an additional 50
bareroot hardwood trees were installed due to a minor landowner encroachment.

The chart below provides a summary of the vegetation counts within plots as of March 2014. All
vegetation plots met the success criteria required for buffer mitigation or Nutrient Offset Nitrogen
credit, as well as the success criteria for stream mitigation credit.

Vegetation Total Stem Count/ Acre Planted Stem Planted, Hardwood Stem Count/ Acre
Plot No. (SMU Credit) Count/ Acre (BMU or Nutrient Offset N Credit)

2 364 364 364
3 n/a 323 323
4 647 323 323

Note that the March 2014 planting took place ĂźĊśʼn the MY5 vegetation counts, therefore, are not
reflected in Table 9 on the following page.
