I am currently assisting in the restoration/creation of a wetland found in southwest Arizona along the lower Colorado River. Part of this effort is also incorporating some sort of recreational use of the area by creating trails. I was wondering if anyone has information on what type of rock would be recommended for these trails and which I should stay away from? Current plans for the trails call for using decomposed granite, but my concerns are using some type of material that may alter some element of the wetland such as its pH or salinity etc... I recall in the past reading an article where a constructed gravel road adjacent to a wetland significantly altered the wetlands water chemistry after heavy rainfall, but I have unfortunately been unable to track it down.
Any information or suggestions on this would be greatly appreciated. Thanks, Tab Bommarito ________________ Thomas (Tab) Bommarito Habitat Specialist II Arizona Game & Fish Department 9140 E. 28th Street Yuma, AZ 85365 (928) 341-4069
