Mariposa Woodland Oak Habitat Enhancement Project <br /> Current Status and Next Steps <br /> In 2003, the POS Division hired IGR for $500 to count and mark the trees that needed to be thinned in <br /> the area. The following table identifies the number and sizes of trees recommended for removal or <br /> snag creation. Marking was done with Jesse Cary -Hobbs who worked alongside Darrin Stringer to gain <br /> experience in this work. <br /> Table 1: Mariposa Woodland Tree Removal Estimates <br /> City of Eugene Ridgeline Trail Tree Marking Project <br /> May 8,2003 <br /> Completed by Darin Stringer, IRM <br /> Trees Marked for Snag <br /> Trees Marked for Removal Creation <br /> Douglas- Oregon Douglas- Oregon white <br /> DBH* fir white Oak Pear fir Oak <br /> 0 - -4 14 277 50 0 0 <br /> 4 - -8 37 44 20 0 0 <br /> 8 - -12 23 2 10 0 0 <br /> 12 - -16 12 0 1 0 <br /> 16 - -20 2 0 4 0 <br /> 20 - -24 1 0 <br /> Total 89 323 80 5 0 <br /> *DBH =tree diameter at breast height <br /> The next step will be to implement the tree removal component which would be completed by City <br /> staff. Some snags may also need to be topped to reduce risk that they may fall toward the trail. This <br /> work would likely be contracted out, possibly to IGR. After the trees have been cut the downed wood <br /> will need to be removed. There are two options: piling chipping and hauling, or jackpotting. As <br /> Darrin Stringer explains, <br /> ...'jackpotting" which is essentially to make small piles the size of a large campfire, put a <br /> piece of wax paper (non -toxic when burned compared to black plastic), and to burn the <br /> piles in November after a few soakers when there is zero risk of fire. Then we can come <br /> in and seed the pile circles to prevent thistles and other weeds. I understand if you are <br /> reluctant to burn. Jackpotting is widely used by the forest service, and it is much cheaper <br /> than a chipping operation. <br /> Darrin Stringer provided a rough quote which will need to be updated. He estimates that chipping and <br /> hauling would cost about $7000 while jackpotting would cost $3,300. Because it is more cost <br /> effective, the jackpotting option is recommended. In addition, it would be valuable to develop these <br /> skills since access for hauling slash out is very limited on the majority of other potential oak <br /> restoration sites. Similarly, the chipping/hauling method will require permission to bring materials <br /> across Janet Reeves property incurring possible liabilities should damage occur.
