Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only

Background The People's Republic of China and the United States of America, in accordance with the consensus recommendation of the 12th meeting of the Plants Committee (Leiden, 2002), prepared a proposal for the 13th meeting of the Conference of the Parties (CoP13; Bangkok, 2004) to include the remaining Asian species of Taxus (i.e., other than T. wallichiana) in Appendix II, but did not propose the inclusion of Taxus spp. from other regions due to the lack of evidence that trade, particularly for the pharmaceutical industry, was adversely affecting species outside of Asia. The proposal for CoP14 Prop. 36 – p. 1 CoP13 therefore only included Taxus chinensis, Taxus cuspidata, Taxus fuana, Taxus sumatrana and all infraspecific taxa of those species (proposal CoP13 Prop.

The ENEMY: Japanese Yew (Taxus Cuspidata) Strategy: Also Known As the 'Tree of Death' As Dedicated to the Gods of Death. Th
The ENEMY: Japanese yew (Taxus cuspidata) Strategy: Also known as the ‘Tree of Death’ as dedicated to the Gods of Death. This perennial evergreen tree grows to a height of 25 foot if in the right site. This pest is planted all over the U.S. in landscapes and as an ornamental. It is quite often used in Christmas wreaths. Its needles are arranged flat on the stem of which forms red berries. The plant grows in sunny or shady sites as long as there is a medium amount of moisture and well-drained soil. The plant is native to Asia. Due to the types of sites it is planted in it does not generally develop a very deep tap-root. Attack: This plant does not spread very rapid as many other plants do. Its biggest attack on our environment is its toxicity to animals. News stories can be found where 50 antelope were found dead or the elk that were found dead in the Boise foothills. Many livestock producers have had livestock die where they were found to have fed on the Yew tree. Dogs have known to have been killed by eating the stomach of animals that have eaten the tree. Defense: Don’t plant it….In fact due to wildlife issues in the certain areaa, the local officials listed it as a noxious weed and landowners have agreed to remove it from there properties and landscape companies are no longer planting it. If you cut it down ensure that you treat the stump immediately after the cut-down process.

Comparative Transcriptome Analysis of Non-Model Taxus Species for Taxol Biosynthesis
Available online www.jocpr.com Journal of Chemical and Pharmaceutical Research, 2015, 7(3):800-805 ISSN : 0975-7384 Research Article CODEN(USA) : JCPRC5 Comparative transcriptome analysis of non-model Taxus species for taxol biosynthesis Prashant Saxena and Balasankar Karvadi * Department of Bioinformatics, Sathyabama University, Chennai, Tamilnadu, India _____________________________________________________________________________________________ ABSTRACT Taxol is a known drug, approved by the food and drug administration in 1992 for the treatment of a wide range of cancers. Taxol is obtained from the taxus plant. Taxus plant has a very long life cycle and the production of taxol from the plant is a tedious process. In this study, we have tried to find new species of taxus which can be able to produce taxol and can overcome the burden of Taxus baccata plant. For this study we have used the next generation sequencing pipeline. In this study, we have collected three transcriptome data of taxus species namely Taxus X media, taxus cuspidata, and Taxus baccata. The transcriptome data contain lots of noise, to remove that noise quality check study were performed to generate high quality data. Once the high quality data were obtained trinity tool was used to generate the high quality reads. Blastx was used to find the homologous enzymes against the high quality reads. The mapping and annotation studies were performed to find out the function of the homologous enzymes. This comparative transcriptome analysis revealed that the enzymes present in the Taxus X media shows higher similarity with Taxus baccata and contains major enzymes which are involved in the taxol biosynthetic process. So the overall postulates of this study decipher that Taxus X media may be used as a new source for taxol production and it may overcome the burden of taxus plant.

Taxus (Yew) Production (Draft) by Mark Halcomb UT Area Nursery Specialist
1 Taxus (Yew) Production (draft) by Mark Halcomb UT Area Nursery Specialist Commonly produced yews: Taxus cuspidata 'Capitata' (Capitata Japanese Yew) W type 4, cone upright Taxus cuspidata 'Densa' (Dense Spreading Japanese Yew) H spreader Taxus x media 'Densiformis' (Densiformis Yew) W type 2, semi-spreading Taxus x media 'Hicksii' (Hicks Yew) H, W type 5, broad upright Propagation Yews are propagated by rooted cuttings. Most of our yew producers buy their liners from liner producers rather than root their own. They will be 6-10 inches tall when lined out. Local liner producers are Carl Bouldin, Myers Cove, Phytotektor, Schaefer, Shadow, and Tennessee Valley Nsy in Winchester. Site Selection Yews require a very well drained soil, like dogwood and peach. Select a site without a fragi-pan; where water never stands. Fertility Yews grow best with a soil pH of 6.0--7.0. A medium to high level of phosphorus and potassium is desirable. Soil test early enough so that any lime, phosphate or potash can be broadcast prior to planting. Problem: Yews generally take on a pale green to a yellowish green color during the winter, possibly affecting sales. In September, 1987, Dr. Will Witte, UT Woody Ornamental Researcher with the Experiment Station, shared some Ohio State University research on how they suggest to maintain dark green foliage on yews throughout the winter. The research suggested 6 pounds of actual nitrogen per 1000 square feet or 264 pounds of actual nitrogen per acre per year. It should be equally split into 3-4 applications per year. Four applications would mean 66 pounds actual nitrogen per application.

The Reproductive Ecology of the Pacific Yew (Taxus Brevifolia Nutt.) Under a Range of Overstory Conditions in Western Oregon
AN ABSTRACT OF THE THESIS OF Stephen P. DiFazio for the degree of Master of Science in Botany and Plant Pathology presented on May 5, 1995. Title: The Reproductive Ecology of Pacific Yew (Taxus brevifolia Nutt.) Under a Range of Overstory Conditions in Western Oregon Abstract approved:Redacted for Privacy The influence of overstory openness on the reproductive ecology of Pacific yew (Taxus brevifolia Nutt.) was investigated on 4 sites in western Oregon over 2 years. The breeding system of T. brevifolia was found to deviate from pure dioecy under a broad range of canopy and site conditions. Production of female strobili was observed on 17 of 58 predominantly male trees, while no male strobili were observed on 57 female trees. Genet sex ratios were significantly biased in only 1 population, where male genets outnumbered female genets by almost 2 to 1. Mean floral sex ratios were significantly male-biased in all populations and ranged from 5 to 12. Pollen-ovule ratios were in excess of 1,000,000 for all populations. In contrast, reproductive effort based on masses of mature strobili were female-biased by a factor of 1.1 to 5 for all sites. Seed masses also varied inversely with elevation. Pollination phenology varied with elevation and overstory openness. Pollen first began shedding at the lowest sites, and earlier in trees under open conditions than in trees with overstory canopy cover. The duration of pollen shedding varied from 3 to 20 days, and tended to be more protracted at lower sites and under open canopy conditions. Most of the variation in reproductive potential, as indexed by strobilus production, occurred within sites and within trees.

The Complete Mitochondrial Genome of Taxus Cuspidata (Taxaceae)
Kan et al. BMC Evolutionary Biology (2020) 20:10 https://doi.org/10.1186/s12862-020-1582-1 RESEARCH ARTICLE Open Access The complete mitochondrial genome of Taxus cuspidata (Taxaceae): eight protein- coding genes have transferred to the nuclear genome Sheng-Long Kan1,2, Ting-Ting Shen1, Ping Gong1, Jin-Hua Ran1,2* and Xiao-Quan Wang1,2 Abstract Background: Gymnosperms represent five of the six lineages of seed plants. However, most sequenced plant mitochondrial genomes (mitogenomes) have been generated for angiosperms, whereas mitogenomic sequences have been generated for only six gymnosperms. In particular, complete mitogenomes are available for all major seed plant lineages except Conifer II (non-Pinaceae conifers or Cupressophyta), an important lineage including six families, which impedes a comprehensive understanding of the mitogenomic diversity and evolution in gymnosperms. Results: Here, we report the complete mitogenome of Taxus cuspidata in Conifer II. In comparison with previously released gymnosperm mitogenomes, we found that the mitogenomes of Taxus and Welwitschia have lost many genes individually, whereas all genes were identified in the mitogenomes of Cycas, Ginkgo and Pinaceae. Multiple tRNA genes and introns also have been lost in some lineages of gymnosperms, similar to the pattern observed in angiosperms. In general, gene clusters could be less conserved in gymnosperms than in angiosperms. Moreover, fewer RNA editing sites were identified in the Taxus and Welwitschia mitogenomes than in other mitogenomes, which could be correlated with fewer introns and frequent gene losses in these two species. Conclusions: We have sequenced the Taxus cuspidata mitogenome, and compared it with mitogenomes from the other four gymnosperm lineages.
