ABSTRACT Historical records indicate that Matelea decipiens (Asclepiadaceae), oldfield milkvine or climbing milkweed, is known from Jackson, Saline, and Williamson counties in southern Illinois, where it is listed as endangered. Although a previous unvouchered occurrence has been noted in the Illinois Natural Heritage database, a recent collection from Monroe County, reported herein, officially extends the range north and west in the state.

ABSTRACT In order to provide vegetation managers with information on roadside habitats in West Virginia, a statewide roadside vegetation study was conducted in 2000. The vegetation along nearly 1,500 km of four-lane highways was sampled in 339 randomly selected 20 m wide strip plots. An index of occurrence class (IOC) for each species was calculated using the product of the percent frequency of occurrence and relative abundance. A total of 467 species were documented, 325 of which were native. Seven families accounted for more than 50% of all species. When ranked on the basis of total IOC values, 15 of the top 25 species were introduced. Mean IOC values for introduced species (6.0) were significantly greater than native species (4.3, p¼0.0013). We propose that despite initial variability of landform, parent material, forest cover types, and climate, the relative similarity of species composition along the highways we sampled was the result

ABSTRACT Logging has recently been used as a restoration tool in Florida scrub, a pyrogenic shrubland ecosystem that often develops a pine canopy in the absence of fire. We studied the effects of logging and fire, alone and in combination, on fire-suppressed Florida scrub on the Lake Wales Ridge in south-central Florida. Restoration goals were both structural (reduce pine canopy, hardwood subcanopy, shrub stem density; increase bare sand) and compositional (increase rare plant occupancy and forb diversity). In 2- and 5-yr posttreatment surveys, all treatments significantly reduced pine density and the hardwood subcanopy relative to the control, but no treatment was successful in reducing shrub stem densities. Burning alone exposed sandy substrate for forb recruitment, but the logging treatments created significantly larger areas of bare sand. Treatments had little effect on species richness and rare species abundance, but two rare species recruited into logged plots. The weak treatment effects on

Juglans nigra (black walnut) is widely distributed throughout the US eastern forest, with high concentrations occurring in Missouri and the Ohio and Tennessee River basins. It is an extremely desirable tree for wildlife forage and timber production on forest land, and for shade, aesthetics, and wildlife forage in urban areas. Current (2009–2010) estimates from US Forest Service Forest Inventory and Analysis (FIA) data indicated that there were 306 million live black walnut trees in the eastern United States with a live volume totaling 112.76 million cubic meters (m3). This resource is currently threatened by the newly discovered presence of thousand cankers disease (TCD) in Pennsylvania, Tennessee, and Virginia. Thousand cankers disease may have been present in these areas for at least 10 years prior to discovery; however, no evidence of TCD in the forest at large was apparent in the crown condition and mortality data collected by FIA between 2000
