Stability analysis of roadside backfill body at gob-side entry retaining under combined static and dynamic loading
<p>The applications of gob-side entry retaining (GER) techniques tends to increase over time as it can increase the minerals recovery rate and reduce the output of the waste. In the literature, only the performance of the roadside backfill body (RBB) at gob-side entry retaining under static loading has been investigated. However, failure mechanisms of the RBB under dynamic loading with various roof cutting angles have not been addressed. This study presented a numerical simulation of the fracture propagation and distribution in the roadside backfill body along the gob-side under combined static and dynamic loadings using the Trigon model built in UDEC (Discrete element methods) software. The influence of the roof cutting angles on the behavior of the RBB was also discussed. The input parameters were determined by back analysis with the field data. Results of the model show that static loading is a bigger contributor to the failure of the RBB compared to the dynamic loading. Several clear fractures were observed at top left and bottom right of the RBB and the fracture was more intensive at top left. In addition, it was found that if the roof cutting angle is 70°, the influence of the dynamic loading on the RBB is minimum, and the area and severity of the shearing failure in the RBB is minimum as well. As a result, it was determined the optimal roof cutting angle was 70° and a combined support measure of "roof cutting + roof support above RBBs + RBB reinforcement" is proposed. The application of roof cutting in gob-side entry retaining (RCGER) techniques in the Lingzhida coal mine indicates that deformation of the surrounding rocks can be effectively controlled.</p>
FIG. 3 in On the Road Again: Assessing the Use of Roadsides as Wildlife Corridors for Gopher Tortoises (Gopherus polyphemus)
FIG. 3. (A) Log-scaled minimum convex polygon (MCP) home ranges compared between habitat types (i.e., ruderal corridors, inland scrub, and coastal strand). Corridor tortoises occupied slightly smaller home ranges but were not significantly different because of the large variance seen in their home ranges. Inland home ranges were obtained from Smith et al. (1997). (B) Log-scaled average distances traveled between tracking events (m) compared between habitat types (i.e., ruderal corridors, coastal strand) but excluding inland scrub for which the data were unavailable. Average distances were not significantly different between habitat types.

FIG. 2. Details of the two distinct sites within Kennedy Space Center, USA, used for the different parts of this study where (A) and (B) correlate to the study sites outlined in Figure 1. (A) Map of the study site where current roadside corridor use was determined via radiotelemetry of tortoises captured along the roads. Eight example minimum convex polygon (MCP) home ranges are colored showing movement confined to areas along the corridor but no movement directly through the corridor. Tortoise 5221 was the only individual observed moving from the corridor to coastal strand habitat over a distance of 500 m. (B) Map of the study site where we assessed the feasibility of roadsides to function as movement corridors. We translocated tortoises (dotted colored lines) from either inland or coastal habitat into the potential corridor. Daily radiotelemetry (solid colored lines) determined if tortoises used corridors rather than straight-line paths to return to their original home range.

Evaluation and Enhancement of Carbon Sequestration Potential of Existing Vegetation along Roadsides
<p>Corresponding data set for Tran-SET Project No. 18HSTSA01. Abstract of the final report is stated below for reference:</p> <p>"The objectives of this study were to evaluate the vegetative composition and carbon sequestration potential of vegetation along a major roadway in Texas. Soil and vegetation were evaluated along IH-35 within Bexar County for composition and carbon content. Three 20 m transects were placed at each site and percent vegetative cover was estimated and above ground plant biomass, and soil was collected from three 0.25 m2 subplots along each transect. Plant and soil samples were analyzed for carbon content. Two non-native grasses, bermudagrass and King Ranch bluestem, were the dominant cover at all sites accounting for > 90% coverage at several sites. Native plants were rare with only one species, western ragweed, accounting for > 5% mean coverage at all sites. Carbon content of plant species was highest for bermudagrass (699 kg C ha-1) and King Ranch bluestem (401 kg C ha-1), and 6 of 7 sites contained significantly more carbon in non-native plants compared to native plants. The highest native plant carbon content was western ragweed with an average of 15 kg C ha-1. Mean soil carbon content ranged from 3.1 to 6.9 kg C m3 -1 among the sites, and significantly (P < 0.05) greater amounts of carbon were recorded in the upper 0-10 cm compared to the 10-20 cm. The photosynthesis rates of Bermudagrass were significantly greater than rates recorded for King Ranch bluestem indicating the former species is highly adapted to hot semi-arid climate of central Texas, but King Ranch bluestem may gain a competitive advantage along roadways during the spring, fall and periods of increased precipitation. The total available area for the vegetation along the IH-35 highway in Bexar County is estimated to be approximately 81.7 ha (201.5 acres). We suggest the area between sites 5 and 6 (25.1 ha; 62 acres) are ideal locations for carbon sequestration using native plant communities including those with larger diameter woody stems such as trees."</p>

Surrounding landscape effect on roadside verges
<p>Semi-natural habitats are declining throughout the world, thus the role of small anthropogenic habitats in the preservation of plants is becoming increasingly appreciated. Here we surveyed the orchid flora of roadside verges in five Central European countries (Austria, Hungary, Romania, Slovakia and Slovenia) and tested how the surrounding landscape matrix affects the overall number of species and individuals, and also different functional groups of orchids. We found more than 2000 individuals of 27 orchid species during our surveys. According to our results, the increasing coverage of agricultural and urban areas negatively affect both the number of orchid species and individuals on roadsides. Our study further suggests, that differences in the surrounding habitats affect which species are found on roadsides, since the increasing coverage of grasslands or forested areas around orchid occurrences had a significant positive effect on the number of grassland or forest-dwelling species and individuals, respectively. Most variance in orchid numerosity and diversity was explained by the cover of the suitable habitat types of the respective taxa in the surrounding landscape of the sampling points. This highlights the importance of roadsides acting as refugia for numerous species and valuable plant communities as well as supporting biodiversity in general.</p>
Roadside rights-of-way as pollinator habitat: a literature review
<p>Pollination of crops and naturally-occurring flowering plants is a critical ecosystem service provided by managed and unmanaged animal pollinators. Insects are the most studied pollinators, particularly managed honey bees, unmanaged wild bees, and butterflies. Bees and butterflies thrive in early-successional habitat featuring grasses, exposed soil, wildflowers, and shrubs, which is consistently found within transportation and utility rights-of-way (ROW). However, intensive management of ROW can reduce the amount of high-quality pollinator habitat; such practices include frequent mowing, broadcast herbicide use, and planting non-native cool season grasses. Here, we review peer-reviewed academic and non-peer-reviewed gray literature describing ROW management practices and their effects on pollinator populations. Both information sources consistently recommend these management practices to provide pollinator habitat in ROW and promote plant and pollinator diversity and abundance:</p> <ol> <li>Reduce mowing frequency and time mowing to pollinator activity. </li> <li>Target herbicide applications to undesirable plant species using backpack sprayers.</li> <li>Plant native seeds, seedlings, or shrubs, leaving some exposed soil for nesting.</li> </ol> <p>We considered threats to plants and pollinators associated with ROW, including traffic volume and mortality, noise, light, and air pollution, and habitat fragmentation. The literature indicates that these threats vary widely across road sizes, types, and landscape contexts and suggests that the overall negative impacts do not outweigh the potential benefits of promoting pollinator habitat in ROW. Landscape context also influences the composition of ROW plant and pollinator communities.</p> <p>Many state Departments of Transportation have incorporated integrative vegetation management (IVM) principles into ROW management, and we summarize a number of case studies here. Restoration projects in high-visibility areas are common; these can lead to public support for additional pollinator habitat enhancement. Implementing new management practices can be difficult; therefore, we discuss strategies to aid in successful adoption, including gathering public support, collaborations between public and private agencies, and innovative funding opportunities. While assessing vegetation management impacts on bee and butterfly communities in ROW is a rapidly expanding area of research, there are still many gaps in current knowledge. We conclude this report by addressing these gaps and provide suggestions for further study.</p>
