Scientific and Technical GuidanceGIS AnalysisNEWS: Roger Tomlinson, scientific advisor to Salvemos al Rio Laja and "Father of GIS" receives Distinguised Career Award from Assocation of American Geographers April 2005. GIS (Geographic Information Systems) analysis is being conducted by Dr. Roger Tomlinson of Ottawa, “the father of GIS,” to prioritize locations where river work can be done to the best advantage. The Mexican government's Instituto de Ecologia and hydrologists from the University of Mexico and the U.S. Forest Service are assisting. To learn more about GIS see "An Overview: The Future of GIS" by Dr. Roger Tomlinson and the USDA Forest Service discussion of Geographic Information Systems to analyze surface features. OrnithologyAn avian census was established in the watershed forest, Santa Rosa, in 1993 with funding from the US Fish and Wildlife Service and technical assistance from the Theodore Roosevelt Sanctuary in New York. The census has been ongoing. A preliminary census of water and shorebirds in the manmade lake near San Miguel was initiated in 2000 by the Theodore Roosevelt Sanctuary, with funding from North Shore Audubon Society in New York, which established the lake to be a valuable location for water and shore birds. This survey will continue with funding provided by the North American Wetlands Conservation Council. Stream EcologyStream Ecology analysis is being conducted by Cornell University. By studying invertebrates in numerous streams, work sites can be prioritized. Invertebrates indicate which areas of the watershed are polluted and which are healthy and should be high on the list of work sites. Clean water above helps freshen streams below. River RestorationExperts from the U.S. Forest Service have provided intensive instruction on river restoration techniques to selected candidates from this area. As restoration continues, they will also provide follow-up instruction. |
