Do not click links or open attachments unless verified. Send all suspicious email as an attachment Report Spam. Katie — Axiom completed the supplemental vegetation survey work at Pancho last week. They performed five survey transects (4m x 25m) within the area of vegetation plots 11 and 12 (see attached map for specific locations). I asked Axiom to compare the results of their survey work to the original planting list to determine which species were planted and which were natural recruits. Axiom flagged planted stems with white flagging, and natural recruits with orange flagging. When totaled, all vegetation transects met success criteria based on planted species and the natural recruit of planted species, averaging 566 stems per acre. Diospyros virginiana (common persimmon) and Juglans nigra (black walnut) are two high desirable species that were not on the planting list but have naturally colonized the area. When these species are added to the total, the area averages a density of 834 stems per acre. During the site visits, we also observed pine and sweetgum recruits, when these two species are included, the stems per acre density is above 1,500 per acre. I have attached the data for your review. With this additional survey data and the information I provided in my e-mail on April 4t" (below), I think it is clear that the area is meeting success. Diffused flow is being accomplished, sediment is nowhere close to reaching the receiving waters, and the buffer is naturally regenerating with primary and secondary successional species. Please do not hesitate to contact me if you would like to discuss the data presented. Sincerely, Raymond H. Raymond J.

The area measures 1.0482 acres or 6.341% of buffer & nutrient generating acreage. You will note that I did not detail out the individual open areas and was broad with my delineation. Credit Area Acres Buffer 5.2 Nutrient 11.33 SUM = 16.53 Area of No. of Sup. Sup. Concern AOC in Sq. M Veg. Plots (100 Area Sup. Survey Arei (4,046.86 sq. Veg. % of Area of (AOC) m per. ac.) Sq. Meters Survey Concern) (Acres) ea) Area 1.0482 4242.0279 5 500 11.787% AOC as a % of Buffer & 6.341% Nutrient Credit Area The attached figure also details where I have asked Axiom to perform supplemental monitoring. When we do supplemental monitoring, we typically do plots that equal 100 sq. m. (same as a CVS veg. plot). Axiom will be performing five transects within the area of concern covering 11.78 % of the area in question. I have asked Axiom to follow the typical CVS protocol when performing the survey work. We will try our best to identify planted vs. natural recruits and will use the original planting list as a guide. Feel free to give me a call if you have any questions. Thanks, RH Raymond J.
