The policy implications of agricultural losses caused by high concentrations of ground level ozone have been highlighted by a recent study. The study modelled ozone impacts on 14 of the most important crops grown in the Greater Thessaloniki area of Greece. The results provide information about differences in scale of losses and economic impacts across the region which may be useful in designing agricultural subsidy schemes.

A study in the Czech Republic has found a link between exposure to certain air pollutants and an increase in DNA damage for people exposed to high levels of the pollution. They found that breathing small quantities of a polycyclic aromatic hydrocarbon (PAH), called benzo[a]pyrene (B[a]P), caused an increase in the number of certain ‘biomarkers’ in DNA associated with a higher risk of diseases, including cancer.

LYNCHBURG —Over a week after the rain and wind of Tropical Storm Michael took aim on the Commonwealth, the Virginia Department of Transportation continues to assess roads and bridges in the Lynchburg District affected by the storm. By the time Michael exited the area, over 220 road and 360 structures were under water and as of today (Friday, October 19) only six short-term closures, in addition to the long-term closures below, remain.

LYNCHBURG, Va. – US 58 over Sandy Creek at the Halifax/Pittsylvania County line has been closed to traffic since Tropical Storm Michael struck the Commonwealth in October and motorists have used a lengthy detour that required travel in North Carolina. Weather permitting the eastbound structure will re-open to one lane of traffic in each direction today, Wednesday, November 7.

The Malheur model for fire-caused delayed mortality is presented as an easily interpreted graph (mortality-probability calculator) as part of a one-page field guide that allows the user to determine postfire probability of mortality for ponderosa pine (Pinus ponderosa Dougl. ex Laws.).

Incidence and effects of tree damage by black bear (Ursus americanus altifrontalis) in a 50-year-old, coast Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) plantation are described. Bears girdled or partially girdled 35 dominant or codominant Douglas-fir trees per acre, but only in that portion of the plantation that had been interplanted at age 4 with red alder (Alnus rubra Bong). No red alder were damaged. Bears damaged Douglas-fir in this stand on at least four occasions between 1929 (planting) and 1991. Fully girdled Douglas-fir (six per acre in 1976) died within 2 to 14 years. Of the 29 per acre partially girdled trees, 17 percent died in the 16 years of observation, compared to 9 percent of nondamaged trees. Crosssectional growth of surviving damaged trees exceeded that of matched, nondamaged trees by about 30 percent at three heights on the bole: 6 ft, 4.5 ft, and immediately above the damaged area. Death of six large Douglas-fir trees per acre reduced live stand volume of this species for about 6 years after bear damage until growth of the remaining trees compensated for the volume lost to mortality. Confirmation of the stimulating effects of bear damage on subsequent tree growth is needed at other locations.
