Mr. Young. Mr. Davison, did the estimate of 345,000 acres of 

 coastal wetlands come from the Fish and Wildlife Service? 



Mr. Davison. Yes, sir. It is an estimate from the National Wet- 

 lands Inventory. It is an initial estimate of the number of acres of 

 estuarine intertidal vegetated wetlands, basically salt marsh. 



Mr. Young. Could you provide me with the maps and the areas 

 where it demonstrates where coastal wetlands are and how you de- 

 termine where coastal wetlands end and the noncoastal contiguous 

 wetlands begin? 



Mr. Davison. We could certainly provide you with that informa- 

 tion. The estimate was based on 1,000 sample plots, each four 

 square miles in size. 



Mr. Young. Who did it? 



Mr. Davison. The National Wetlands Inventory of the U.S. Fish 

 and Wildlife Service. 



Mr. Young. When was it done? 



Mr. Davison. I don't know when it was done. The results are 

 scheduled to be published next year. 



Mr. Young. I want to know the dates, who did it, was it contract- 

 ed out? I want to see the maps. 



The main justification for the administration rejecting the classi- 

 fication system is that it would be extremely expensive, administra- 

 tively unworkable, to classify the Nation's wetlands, especially in 

 Alaska. 



How is it too difficult to map and divide the low, medium and 

 high 45 percent of the land mass in Alaska and approximately 5 

 percent of the land mass in the lower 48, but yet the Secretary 

 claims that the Biological Survey map which came out of this Com- 

 mittee contains every ecosystem and species? 



How can he do one and say it is not expensive and now it is ex- 

 pensive. That is your department. Do you see what I am saying? 



I will just settle for Alaska, all right? I will just settle for that. 

 On the one hand, you say in your report that it is too expensive. 

 On the other hand, we are going to survey the whole United States 

 for everything, wildlife species, endangered species, wetlands, wa- 

 tershed. 



Mr. Davison. I think it has to do with the level of the resolution. 

 The National Wetlands Inventory maps are high altitude maps 

 that are not detailed enough to draw property boundaries or delin- 

 eate regulation wetland boundaries, and that is why they are iden- 

 tified as not for use for regulatory purposes. 



Mr. Young. But my question is: On the one hand, your boss is 

 saying we can do it reasonably priced for everything and now he is 

 saying it is too expensive. I don't understand that. I want to know 

 where this report came from. Were you the brains behind the 

 report on Alaska? 



Mr. Davison. No, sir, I was not. 



Mr. Young. I would like to find the brain, unless it is in an insti- 

 tute somewhere. 



Secondly, Mr. Wayland, what development model did you use to 

 determine Alaska could fill all its remaining coastal wetlands 

 under the 1 percent rule. What model did you use? 



Mr. Wayland. Although I refreshed my memory with this last 

 night, Congressman Young, I took the occasion after your opening
