There are no raw data with the submittal, Therefore, the Division cannot <br />verify results, tables, statistics or conclusions. <br />2. No sample adequacy calculations were performed. We would also need raw <br />data to independently verify these calculations. <br />3. No results are given for woody plant density. <br />4. There are no results from the reference areas for reclamation success <br />comparisons. <br />5. Vegetative production was not sampled. <br />6. Sample dates were not specified. <br />
