(b) changes in effects of predators 



(c) increase of hunting pressure 

 (3) present status of common species 



(a) abundant 



(b) scarce 



(c) endangered 



(j) Strip or Open Cut Mining 



(1) extent of denudation 



(2) extent of revegetation 



(3) effects on wildlife 



(4) economic factors for and against 



(2) Which of the 16 "violent reactions" listed in chapter 8 are 

 affecting your county? Record specific evidence. 



(3) What remedial measures are underway in regard to Activi- 

 ties 1 and 2 ? This is a question of much importance, not to be avoided 

 in any study of this nature. It is an essential followup of Activity 1, 

 but may be done simultaneously with each section. From the as- 

 sembled information a judgment may be made of conservation prog- 

 ress and what remains to be done. It will form a basis for community 

 planning, and such planning should be indulged in by students. 



(4) What is the trend of rural population in your county over the 

 past 40 years, more or less? A steady decline from a high point 

 may reveal serious damage to the climax conditions of the landscape, 

 forcing man off the landscape. There may, of course, be other factors 

 bearing on population decline. 



(5) We would hardly expect rural people to be unable to sup- 

 port themselves. The land is commonly supposed to be the escape 

 hatch from economic depressions. But, if your county is one where 

 erosion is serious, look up the records of direct relief for the open 

 country folks during the depression of the thirties ; if the records are 

 not easily available, inquire of older people who may know. 



(6) If there has been a school dental survey in your state, it will 

 be informative and convincing to compare a map showing the average 

 occurrence of defective rural teeth in various counties with an erosion 

 map of the state. City teeth may not reflect poor local soils because 

 of the large percent of foods shipped in.
