7ithiieuf cover and woody plant density will be sampled accoroing to the methods outlined under Task 1. The actual sampling period will be determined during the growing season. (nfnrmation on local Conditions, includingtcmpcraturc and prccipitatian trends, will be obtained from wFU during the spring and suntmer.'['ttis information will he used by Grcystane to estimate the period of maximum vegcwticn cover.

This assessment will include thu vegetative cover and woody plant density samplinb of tasks 1 and 2. [n addition, hcrhacCOUS praductiunsamplingwillbccunductcd. The sampling and sample udcyuacy calculation mctlwds fur all three suncys will he the same as dcscribcd for task 1.

Huts ever, the sampling will probably be conduct- ed later in the SCa50n t0 more accurately estimate mean herbaceous production. Task 4 -Third Test Plot Assessment The third test plot assessment will occur during the 1995 growing season. Na activity is planned for the 1994 growing season. Sampling will consist of sun~cys of vegetal ive Inver, herbaceous production, woody plant density, and plan[ rooting depth. Estimates of cover, production. and woody plant depth will 6c Determined with the same methods dcscribcd under task 1. 405 UMut sweet Lakc•~ Colorado aoz:a _. __ ,,.~,onv_a.)6 Sail pits will Mc excavated to czposc plant roots. For major species, the depth of these exposed cools will be measured and recorded. These data, along with information extracted from the litera- turc, will be aced ur evaluate rooting depth for plants in each test plot.

'fltcsc factors include plant density and the numhcr nCmaj~r species prescnt. Bct:ausc pWnt density and number of spcciu successfully cstahlishCd on a plot can vary widely and depend hCavily on climatic conditions prescnt at the site over the next five to six growing seainns, the ultimate numhcr and dimensions of sail pits cannot be determined at this time. Fnr the purposes of this proposal, we arc assuming .¢ soil pits will be necessary fur each tu,t plot. Task 5 -Report Preparation and Reproduction The objective o[ this lack is to prepare, reproduce, and distribute project reports. Four reports arc anticipated. Thrcc will he interim reports present- ing the results of the sun•eys conduc[cd under Tasks 2 and 3. The fourth report will be the final rcpnr[ and will be prepared following the 1995 licld effort (Task ~t). !twill prescnt all information collected over the entire prnjectand determine the revegetation success of each test plot. Grcvstonc anticipates preparing draft and final versions of each report. Five topics of each draft will be submitted to WFU for review. Once WFU's review Comments are received, Grcystone will prepare the final version. Five topics of the final version nleach report will he submitted to WFU upon, completion. Copies of each final report will also be sent to C~tLRD, unless Gfcystnne is directed otherwise by WFU.
