i <br />-14- <br />- ~ RE~iDLTS AND DISCDSSICN <br />Those studies dealing with the entire study area,exclusive of individual <br />vegetation types are presented first. These include vegetation type <br />mapping and vegetation species ernposition. }y3~a1;^A vegetation data <br />such as tree density and basal area, Dover, fra;uerxy, prWuctivity and <br />shrub heightg gathered in different vegetation types on Nucla Mine are <br />presented below: A description o£ the major vegetation parameters <br />ueasured and an evaluation of samplin3 adequacy concludes the report sec- <br />tion. Faw aryl analyzed data are provided on orn~uter print-outs in Appen- <br />dix E. Simnary tables are utilized in the text where appropriate. <br />Nhather conditions within a given year, notably the amount and nortthly <br />distribution of precipitation, can have a considerable effect on ~~-*~~^ <br />vegetation parametew, especially Productivity which, during unusually <br />wet years, may increase dramatically. Therefore, in the interest of <br />• - qualifying the vegetative data base presented in the report for the <br />1979 9~i3 season, precipitation data gathered at a nearby weather sta- <br />tion are included for the 1979 gxcxrirg season a~ for the six months <br />preoeedi<g the 1979 growirnJ season (Table 2). Precipitation data for the <br />six marith period prior to the grc7wing season is irgoxtant because the <br />amount and distribution of precipitation durity this period influence <br />total soil ~misture and thus, the amount of moisture -- `'`le to plants <br />during the £ol3owirg growing season. . <br />VEL;EIATIVE TYPE [+WPPING <br />Delineation of vegetation types on the study area is depicted on Map 1, <br />("Vegetati.~ Types").
