F -- VEGETATION AND CLIMATE CHANGE PROJECT ASSESSMENTS DUE 071299 POC Marilyn Hutchison, Purchasing Agent, 303-236-5900, x327, or FAX 303-236-2710 E-MAIL: USGS, CR, Acquisitions & Federal Assistance, mhutchi@usgs.gov. Concerns having the ability to furnish the services described herein are requested to give written notification (including the telephone number for a point of contact) to the procuring office above within 45 calendar days from the date of this synopsis. The US Geological Survey is conducting on-going research on both past and future vegetation and climate changes in the western United States. The USGS requires data on the potential scope of the environmental effects of climate changes in terms that are accessible to land managers, policy makers, and others who manage resources or estimate future hazards. The contractor shall provide unique numerical analysis capabilities, software, visualization tools, and experience for the analysis and illustration of the relations among climatic variables and vegetation distributions for: 1) the analysis of gridded vegetation and climate data using response surface methodology; 2} the estimation of past and future vegetation distributions from the output of numerical climate models; 3) the estimation of past climatic parameters from fossil plant assemblages; and 4) the scientific visualization of the climatic parameters that potentially control modern plant distributions. Datasets required include: 1) vegetation data and quantitative modern vegetation/climatic relationships for comparison of observed conditions (both past and present) with the results of numerical model simulations and 2) statistical relationships between vegetation and climate for use in analyzing climate models and estimating amplitude on environmental changes through time. Based on information available at this time, and in accordance with 41 U.S.C. 253(c) (1), implemented by FAR 5.302-1, the Government considers the services specified as a sole source from University of Colorado, Institute of Arctic and Alpine Research, Boulder, Colorado, and proposes to negotiate a contract with that firm on that basis. However, should additional sources be identified, they will be considered. Firms who feel that they can furnish the required services are invited to submit in writing an affirmative response to this announcement, and such other materials which correspond to the required items stated herein. This information will be evaluated and used to determine if competitive opportunities exist. Since no solicitation document exists, requests for such documents without accompanying information will be considered non-responsive to this request without further consideration. This notice may represent the Government's only official notice of this procurement. See Note 22. Posted 05/28/99 (W-SN337292). (0148)
