Dale, Nice to see some of this data being updated. I was looking at the Clarion River Rucker Index and data from more recent trips to the river. Do you have the measurements Carl and I took between the Gravel Lick Bridge and Mill Creek from Oct 2008? Anyway. almost all of the trees in the upper end of your Rucker index are from Cook Forest itself. However three are some heights for other species outside of the park that would make the tallest for the speciesin the Clarion River corridor.: http://www.nativetreesociety.org/fieldtrips/penna/clarion_river_rucker_index_pa.htm (Sept 2008)
Dotted hawthorn 2.3 41.7 Portland Mills Juneberry N/A 67.5 Portland Mills Shagbark hickory 4.5 113.6 SGL-Piscataqua N. red oak 10.1 126.7 CCSP-River Trail Red maple 8.2 106.4 CCSP-River Trail Sugar maple 6.4 110.4 CCSP-Irish Rock Trail Yellow birch 6.6 99.2 CCSP-Minich Run doted hawthorn 2.5 43.4 Millstone Creek Am. Hornbeam 2.9 38.0 Millstone Creek silver maple 9.7 107.3 Portland Mills staghorn sumac 1.7 36.9 Portland Mills sycamore 4.8 130.6 Portland Mills CCSP is Clear Creek State Park a few miles upstream from Cook Forest. Millstone Creek Area http://www.nativetreesociety.org/fieldtrips/penna/millstone/millstone_creek_area.htm is farther upstream along the Clarion than Clear Creek State Park, but not nearly as far as Portland Mills. I am not sure where the SGL at Piscataqua is located. - I believe it is below the Gravel Lick Bridge a few miles downstream from Cook Forest. I know there are some taller black gum and witch hazel along the river south of the park that Carl and I encountered on our canoe trip in October 2008 http://www.nativetreesociety.org/fieldtrips/penna/gravellick/clarion_river_gravel_lick_to_mil.htm but unfortunately we did not measure them. At the time we did not realize they would be the tallest documented yet in the corridor.
