<br />C <br />C <br /> <br />14 <br />pine-oak vegetation type. Again, the occurrence of dense litter and • <br />shade from the tree canopy restricted abundant herbaceous (understory) <br />growth. Grass species and several fortis were dominants. <br />Cover values for the willow carr reference area are presented <br />in Table 13. Artemi.sia dracunculus had a mean cover value of 8.5%. <br />Linaria vuloaris had a mean cover value of 5.6", Carex sp. had a mean <br />cover value of 5.5°6, Cirsium vulgare had a mean cover value of 4.7%, <br />•)uncus sp. had a mean cover value of 4.4°;, and Eriaeron speciosus had <br />a mean cover value of 3.4%. The remaining species had mean cover <br />values of 2.8% and below. Most of the crass species fell into this <br />lower category. The total mean herbaceous cover was 49.5%, litter <br />accounted for 44.4% of the cover, and bare ground accounted for 5.9%. <br />Plo rocks were encountered. <br />rented in Table 14. Linaria vulgaris had a mean production of 12.9 <br />gins/m2, and Juncus sp. had a mean production of 11.8 gms/m2. Carex sp. <br />had a mean production of 9.3 gms/mZ, Artemisia dracunculus had a mean <br />production of g.2 gms/mZ, and Cirsiuin vulgare had a mean production of <br />8.1 gms/m2. The remaining species had production means of 3.9 gms/m2 <br />Production values for the willow carr reference area are pre- • <br />and belor+. The total mean production for the o-+illoti•+ carr reference <br />area +•,as 74.5 gms/mz. <br />Density ~neasurer~ents for the rrillor+ carr reference area are <br /> <br />presented ir, Table 15. iJo trees nr saplings ~•+ere encountered. In the <br />shrub category, Salix exigua had a mean density of 1.1/m~, and Rosa <br />woodsii had a mean density of 0.3/m2. The total shrub density o-+as <br />1.4 individuals/mz. <br />
