William F . Jennings 360 Mart i ri Dr . Boulder , Colorado 80303 303-494-5159 July 25, 1986 Dick Antonio Open Space Agricultural Manager Real Estate Services/Open Space 1405 S . Foothills Hwy Boulder , Colorado 80303 Dear Dick : As you have requested during our meeting this morning, I am submitting a proposal for an inventory of the Spiranthes diluvialis populations on the South Boulder Creek floodplain in the vicinity of US 36 (Denver/Boulder Turnpike) , generally in the northeast quarter of section 9, T1S R70W. I think that for the area of densest concentration, about two days of field work , composed of mapping and counting, should be sufficient to delineate the populations . You would have to provide me with aerial photos or a large-scale topo map (at least 200 feet to the inch) to use as a base map. If you want some or all populations flagged, then a supply of flags would be required. I would criss-cross the fields both north/south and east/west to ensure complete coverage . Each population, cluster , or outlier plant would be noted on the base map. Additionally, I would collect botanical specimens to distribute to the major regional herbaria ( such as Univ. of Colorado, Colorado State Univ . , and Univ. of Wyoming) and to Dr . Sheviak at the New York State Museum. It would probably be worthwhile to take some photographs of the plant to accompany the inventory, so that interested parties can see what the plant looks like out of season without having to resort to herbarium specimens or a written description. For two days of field work, an annotated map, a short (2 or 3 pages at most ) report , some photographs, and botanical specimens , I would charge $ 100 per day. if, at the end of the two days of work, you decide to extend the contract so as to cover other areas , 1 would maintain the same rate . However , I do riot think that populations as large as the South Boulder Creek/Turnpike population will be found, so a point of diminishing return will likely be reached very rapidly. On the other hand , this is really the time to do an exhaustive search of Open Space lands , as the plant is nearly impossible to find at other seasons . I am familiar- with 10 other rare plants that are found on the city Open Space, so it may be worthwhile to combine this search with search for other rare species .
