IKONOS-Based Juniper Extraction

During the Fall 2003 - Spring 2004 field campaign, 441 trees of twenty-two species were surveyed. In addition 166 trees, greater then 30 cm DBH were extracted from the Bloody Hill Database (Mlekush et al., 2000). The species of the total 607 historic trees, their abundance and the per species average DBH have been qunatified. The field tally shows that the majority of the trees are in good health, with relative low amounts of fuel accumulation and juniper encroachment.

Chinquapin Oak (Quercus muehlenbergii) is the most dominant species in the sample however the average dbh of this species is only 43.7 cm. Black Walnut (Juglans nigra) is the second most dominant species sampled with a higher average dbh of 50.3 cm. The largest dbh of 128.2 cm is that of a Bur Oak (Quercus macrocarpa), located near the Skegg Branch Stream adjacent to the Park Tour Road., the second largest dbh belongs to a White Poplar (Populus alba) near the Ray Springhouse.

The fuel load, health, dbh, height and juniper encroachment based on the field assessments were also mapped.
