Ms. Kerry Sullivan <br /> December 22, 1992 <br /> Page 5 <br /> Page 25 - 4.13-1(d) <br /> "It should be noted here the small sapling planting project presently <br /> underway in the south central part of the site cannot be considered <br /> adequate mitigation for the loss of critical Swainson's hawk nesting <br /> habitat because it would take nearly 100 years for such a stand of young D56 <br /> oaks to grow to the size required by this species for nesting." <br /> According to Pam Muick, some oak trees will be sufficient size for nesting in 30 years. <br /> We believe the habitat has been enhanced by the cutting of the trees because the <br /> hawks now have additional acreage to forage. <br /> Page 28 - Impact 4.13-3 The 1roposed "restoration" of Tracy Lakes wouldrq eatly <br /> reduce or eliminate the water bird habitat value of two thirds of this historic seasonal <br /> wetland site. <br /> "The excavation of all of North Tracy Lake and approximately half of <br /> South Tracy Lake would convert these present seasonal wetland habitats D57 <br /> to relatively deep (15 to 25 feet), steep-sided small reservoir lakes." <br /> Not all of Tracy Lake will be excavated, only the far western end. <br /> Page 29 - Mitigation Measures 4.13-3(b) <br /> "End the current practice of periodically tilling the drying portions of lake <br /> basin so that aggressive pioneer weeds may then invade the entire area." D58 <br /> The property is a working ranch. The lakes are tilled for cultivation of crops. <br /> Page 29 - 4.13-3(d) <br /> "Retain a hydrologist to design a dry year summer water maintenance <br /> program for South Tracy Lake. Sources of water for such a program <br /> would presumably be the North Tracy Lake reservoir or wells." D59 <br /> How does the author propose to pay for the installation of the well and electricity to <br /> pump the water? <br /> VI-79 <br />
