Estimating Pre-treatment Variation in the Oak Leaf-chewing Insect Fauna of the Missouri Ozark Forest Ecosystem Project (MOFEP)

Abstract

We describe spatial and temporal variation in the insect herbivore communities associated with the MOFEP, prior to application of contrasting cutting regimes. No pre-treatment differences were found in total insect density on either black (Quercus velutina) or white oak (Q. alba) during 1993-1995. There was great seasonal variation in insect abundance on both host species as well as high variation across years for white oak. White oak on north- and eastfacing slopes tended to have more insects than white oak on southand west-facing slopes. Sites under the auspices of the Missouri Department of Conservation for a longer time had higher insect densities than more recently acquired sites.
