Tom Colbert <br /> Date. january 10, ; 985 <br /> Re: rYOoay ,^.lant me^Sit'` Sams:'nn f0• 4no r r,�S , ,-,S We <br /> exp 1 orat i on riaa <br /> ? Ti,e veaetatic^ community comcrisir.q the roar cor dor : ,;,c mappel <br /> anc sam led in the orlainai vegetation oaseline inventory done several <br /> years aqo by WRD. The area encompassing the road corridor was maooem as <br /> part of this inventory as the soruce/fir parHana vegetation type. Tne <br /> road corridor area was not sampled, n,owever. But a considerable area of <br /> this vegetation type was sampled in the original inventory and a reference <br /> area was established. Therefore, information contained in the Coal Bann <br /> Mane permit application already includes quite a bit of information about <br /> this vegetation type. Sample aaeauacy was achieved for tnis vegetation, <br /> type in the original vegetation inventory. <br /> This situation is exactly the same as the situation with the asper <br /> vegetation type at the Sutey property. in that case, the Division deemed <br /> it not to be necessary to re-sample this type completely There should be <br /> no reason to do it for the proposed roam either. (See Map l i l-i^-2 of the <br /> permit application.) <br /> 2 According to policy of the Division, woocy olant density 3amplinq !_ <br /> not remained for communities where woody pianr cover is less tr un ' S <br /> percent. The measured cover for wooay species for the gas well <br /> exploration road is only 7.4 percent. Altnougn tree canopy cover was <br /> not measured, it is iikely that comoined woody plant overstory ana <br /> understory cover is less than 15 percent for the gas well exploration <br /> road area by itself (the spruce/fir oarklano type considered over the <br /> entire inventoried area does nave woody plant cover greater than 15 <br /> percent). The original vegetation baseline inventory states that <br /> conifers..."although visually dominant...contributed only 2.5 percent <br /> cover, owing to the patchiness of their distripution." Therefore, the <br /> necessity of woody plant censity samplinq at all is doubtful, according to <br /> the Division's own definition of a woody vegetation type, if the inventory <br /> of the road corridor vegetation were to stand alone. <br />
