Back in 2002 Dr. Robert Van Pelt published a list of the World Rucker Index on our discussion list:
Bob, et al.,
I applied the Rucker Index to my database to uncover all of the places that exceed 200. Here are the results:
Rucker Index locations over 200
United States 292.8
Canada/British Columbia 235.9
Olympic National Park 233.7
Vancouver Island 225.4
Prairie Creek Redwoods 219.1
New South Wales 201.4
The low diversity of trees in some Western forests quickly reduces the Index to below 200. Humboldt Redwoods SP, for example, has the world's tallest tree, and 86 trees over 350'. Due to the overwhelming dominance by redwood, the Index drops below 200 after only six species are included!
Borneo will probably make this list, but good data are scarce.
This list is certainly outdated, and I don't have a list of what tree species were included in each list. The Hyperion tree by itself would push the index for the World, North America, and California up by almost a foot. Let us try to compile a new Rucker Index Listing for each of these localities and add in the Eastern united States and Europe.
Olympic National Park
Prairie Creek Redwoods
New South Wales
Eastern United States
Ideally I would like to see the tallest 20 species listed along with location (state or country) for each category. For some we may not have the data to do so, but lets give it a shot and try to get at least an updated 10 species Rucker Index for most of the sites.
