Title: Ten-year growth of woody species planted in reclaimed mined banks with different slopes

Abstract

In landscape reconstruction in an opencast coal mine, a gradient of slopes can be obtained. The slope gradient can affect different processes, such as plant growth, especially in semi-arid conditions. On the other hand, to favor the heterogeneity of habitats and ensure long-term restoration, late successional woody species have been planted but with heterogeneous results. In this study, the effect of a slope gradient (from 11.4 to 15.5 degrees) on the growth and survival of five Mediterranean woody species 10 years after the reconstruction of mining banks was evaluated. Slope gradient reduced height growth significantly from 10 cm degree{sup -1} (lentish) to 25 cm degree{sup -1} (pine) in 10-year- old woody species. This gradient also reduced basal diameter growth from 0.22 mm degree{sup -1} (juniper) to 0.58 mm degree{sup -1} (pine). Survival and slope were not significantly correlated. Growth and survival of the 10-year- old woody species were equal to or higher than those of the same species in other afforestations in semi-arid conditions. This outcome demonstrates the adequacy of species and applied techniques of restoration that allow a long-term reliability of reclaimed mine slopes.

  • Steep north- and south-facing slopes on an artificially formed earth mound were seeded with cheatgrass in the autumn of 1971 and left unattended. In 1978, canopy cover and phytomass measurements were made on both slopes. The vegetative cover on the north-facing slope provided more canopy cover and more live phytomass than the south-facing slope. Live aboveground phytomass was measured at 830 g/m/sup 2/ on the north-facing slope and 163 g/m/sup 2/ on the south-facing slope. The large amount of primary production on the north-facing slope is attributed to temperature-water relationships rather than to soil nutrient differences because the mound wasmore » composed of the same homogeneous mix of soil of common origin.« less
  • The Surface Mining Control and Reclamation Act of 1977 requires that coal mine sites in the United States be reclaimed to establish vegetative cover that is diverse, native, and capable of plant succession. However, there is a question as to whether vegetation established on coal mine sites reclaimed with biosolids is diverse and capable of plant succession. The influx of nutrients with the addition of biosolids leads to long-term dominance by early-successional species, most notably grasses, and consequently, a low establishment of woody and volunteer species. Additionally, many grass species commonly planted in reclamation have aggressive growth habits that leadmore » to their dominance in coal mine plant communities. The establishment and growth of selected grass mixes was evaluated to determine whether alternative grass mixes would be less competitive with woody and volunteer species as compared to commonly used grass mixes. Percent vegetative cover, species richness, and the survival of direct-seeded woody species were assessed for each treatment grass mixture. It was found that Poa compress and a mixture of P. compress, Panicum virgatum, and Trifolium repens provided adequate coverage while still allowing the highest species richness and survival of woody species. Use of these species mixtures in coal mine reclamation with biosolids in the eastern United States would likely lead to establishment of a more species-rich plant community with a greater woody species component while still providing erosion control and site protection.« less
  • Seeds of eleven woody species were exposed to 2.3 cm/wk of simulated sulfuric acid rain at pH values of 3.0, 3.5, or 4.0, or to a simulated control rain at approximately pH 5.6. All treatments also contained a neutral mixture of cations and anions based on concentrations reported for Hubbard Brook, N.H. Seeds or seedlings were subject to ambient conditions, except deposition. Seeds were planted in winter, 1977; seedlings were harvested the following summer. The dry weights of the top and roots of each seedling were recorded. Although eight species were affected by simulated acid rain, the direction and magnitudemore » of effects varied with species and with treatment. Seedling emergence was stimulated by at least one acid treatment for four species, while root growth was inhibited for one species. Except for one species, whose emergence rate and top growth were both affected, effects were confined to one measured parameter.« less
  • White birch, yellow birch, bigtooth aspen, eastern cottonwood, Japanese larch, and white spruce seedlings were fumigated with 25 pphm ozone for 110 days. Height growth of the white birch seedlings was reduced, but not by a significant amount; growth of the other species was not affected. The number and size of the white birch leaves were also reduced during the fumigation period.
  • HIFU has been recognized as a minimally invasive treatment option for localized prostate cancer. The purpose of the study was to assess with a long-term outcome of HIFU for prostate cancer. From January 1999, a total of 657 patients who had HIFU with at least 2 year follow-up were treated with four different types of Sonablate registered (Focus Surgery, Indianapolis, USA) devices. Thirty-three patients were treated with Sonablate registered 200 (S200) from 1999 to 2001, 406 patients with Sonablate registered 500 (S500) from 2001 to 2005, 200 patients with Sonablate registered 500 version 4 (V4) from 2005-2008 and 19 patientsmore » with Sonablate registered 500 TCM (TCM) from 2007. Biochemical disease-free survival rate (bDFS) in all patients was 59% in 8 years. bDFS in 8 years in patients with S200 and S500 groups were 55% and 56%, and bDFS in 4 and 2 years in patients with V4 and TCM group were 72% and 84%, respectively. bDFS in low, intermediate, and high risk groups were 75%, 54%, and 43% in S200/S500 and 93%, 72%, and 58% in V4/TCM group. Negative prostate biopsy rate after HIFU was 97% in S200, 79% in S500, 94% in V4 and 100% in TCM group. HIFU as primary therapy for prostate cancer is indicated in patients with low- and intermediate-risk (T1-T2b N0M0 disease, a Gleason score of <=7, a PSA level of <20 ng/mL) and a prostate volume of less than 40 mL. The rate of clinical outcome has significantly improved over the years due to technical improvements in the device.« less
