    ABSTRACT: ABSTRACT.–––To determine if manipulation of milkweed’s natural phenology would increase monarch reproduction, strips were mowed in fields in upstate New York in early Jul, late Jul, and mid Aug, 2006, for comparison to an unmowed control. Common milkweed (Asclepias syriaca) was then monitored from Jul 29 through Sep 24 for plant height, vegetative stage, level of herbivory, condition, monarch eggs and larvae, and the position of eggs on leaves and stems. We found that mowing on Jul 1 and 24 spurred the regrowth of milkweed and sustained a more continuously suitable habitat for monarch oviposition and larval development than the control. Mowing on Aug 17 proved too late for recovery of the milkweeds. Significantly more eggs were laid on the fresh resprouted milkweeds than on the older and taller control plants. In the strips mowed on Jul 1, peak egg densities occurred in late Jul; in the strips mowed in late Jul, peak egg densities occurred in early to mid Aug. Depending on the timing of mowing, the milkweed plant height, developmental stage, and condition differed. As predicted, the mowing of fields with Asclepias syriaca extended the monarchs' breeding season and increased overall monarch reproduction. However, timing of mowing was critical and must be determined empirically for different milkweed species and in different locations. This mitigation procedure could be fostered along roadsides, along edges of fields and pastures, in USDA conservation reserve program lands, and along power lines and other rights of way.

    ABSTRACT: Celastrus orbiculatus Thunb. (Oriental bittersweet) is an invasive exotic liana introduced to western North Carolina in the late 1800s that has established in forests across the southern Appalachian region. The twining habit of bittersweet is recognized to have negative impacts on tree growth by constricting trunks, overtopping canopies, and increasing the probability of wind and ice damage. Our study was designed to quantify effects of invasion by C. orbiculatus on Liriodendron tulipifera (tulip poplar) growth. We cored trees on invaded sites with both twined and untwined trees to test for above and below ground competition effects of C. orbiculatus and compared growth to nearby uninvaded sites. Contrary to our expectations, we found radial growth increased after invasion. This increase is likely a release response from a disturbance that allowed C. orbiculatus to become establised. There were many historical ice storms that occured in our region during the time of C. orbiculatus invasion that may have helped it to become established in these stands. Liriodendron tulipifera are known to respond positively after ice storm thinning and this release may mask any initial negative effects of liana competition. The short duration of our study may not have been long enough to capture the transition from the effect of canopy release due to disturbance to competition with C. orbiculatus.
