WILDLIFE <br /> <br />The present fauna on the Martin Marietta Silica property has a <br />rather low diversity with specific populations quite low. These obser- <br />vations have been made over the last seven to eight years while the <br />quarry has been in operation. The observations, not recorded, were <br />made by lay persons and in no wa.y reflects a professional opinion. <br />A number of factors are possible contributions to the low popula- <br />tions of various wild animals: <br />(a) Extensive farming and ranching has resulted in a landscape <br />characterized by pastures and irrigated hayfields and crop- <br />lands. <br />(b) Extensive grazing by cattle and buffalo has reduced the cover <br />for suitable habitat for many species. <br />(c) The development and activity associated with the mining <br />operations also affects the fauna of this region. <br />(d) The entire open area is being reduced by housing and indus- <br />trial projects. With a higher population density, the wild- <br />life population will surely decrease. <br />• The following is a list of animals and birds seen on Martin Marietta <br />property. These animals and birds have been seen by Martin Marietta <br />personnel since 1969. <br />Mamm~lc <br />Cottontail Rabits <br />These rabbits are very popular and can be seen almost daily. <br />Jackrabbits <br />These rabbits are also quite popular. Many of these rabbits are <br />seen in the mine workings among the rocks and boulders. <br />Ground Squirrels <br />These squirrels are seen almost daily. It seems the mining opera- <br />tion has not had much affect on these animals. <br />Coyote <br />The coyote is common locally. Several have been sited on the property. <br />Some coyotes have been taken by predator control operations on adjacent <br />properties in past years. <br /> <br />
