To determine the influence of different restoration methods on litter-dwelling arthropod fauna,
we used pitfall traps to sample in long-term plots subjected to experimental restoration methods
in bottomland hardwood habitat in Sharkey County, MS, USA. For the first 15 yr of the experiment,
treatments included 1) Native ?natural? regeneration (NR); 2) Oak acorns (Quercus nuttallii) directly
seeded (SEED); 3) Oak seedlings planted (PLN); and 4) Oak seedlings interplanted between
the rows of a cottonwood (Populus deltoides) plantation (CW), in a randomized complete block
design. The blocking factor in the experiment reflected differences in elevation which are related
to susceptibility of the different blocks to flooding. After 15 yr (in 2006), the CW plots were
divided into split plots with four additional experimental treatments applied: 1) cottonwoods
clearcut and allowed to resprout to coppice, 2) cottonwoods clearcut and sprouts treated with
herbicide, 3) cottonwoods thinned 50%, and 4) control (cottonwoods left unharvested). Findings
from quarterly (seasonal) sampling one year prior to cottonwood harvest suggested the
collembolan family Sminthuridae was affected by block, but these effects depended upon the
season of sampling. In winter, this group was significantly more abundant in blocks with higher
elevation, whereas in summer the lower-lying block had greater abundance. Other groups
exhibited significant responses to the blocking factor during Summer, including Formicidae,
Entomobryidae, Acari, and Carabidae. In general, these groups were more abundant in the
lower-lying block, possibly indicating moisture dependence in these organisms. The sminthurid
collembolans also had variable responses to the restoration treatments. They were more
abundant in CW plots than in NR plots during the summer sampling, but the opposite pattern
was observed in winter. Other organisms showing restoration treatment effects included three
(Sphecidae, Hemiptera, and Hypogastruridae) significantly more abundant in the CW, and one
(Orthoptera) more abundant in the NR treatment. These results suggest that CW treatments
may foster forest litter-dwelling organisms (and possibly jump-start their associated functions)
in hardwood restorations on the Mississippi Delta. Data from two dates following the
implementation of the cottonwood harvest treatments will also be presented and discussed. MenosTo determine the influence of different restoration methods on litter-dwelling arthropod fauna,
