All five fixed vegetation plots have shown a positive trend in average stem height. The average stem
height across fixed vegetation plots is 10.2 feet, with individual plots ranging from 6.9 to 16.6 feet.
Vegetation plot 1 has an average stem height of 6.9 feet, which includes a resprouted willow oak that is
13 cm tall. If this stem were removed from the average stem height calculation, vegetation plot 1 would
have an average height of 8.7 feet, which exceeds the seven -foot height requirement. The site has
exceeded the MY5 requirement of an average stem height of seven feet and is on track to close out at
the end of MY7.
