Emerald Ash Borer Coleoptera: Buprestidae Current Rating: None Proposed Rating: A
CALIFORNIA DEPARTMENT OF cdfa FOOD & AGR I CULT URE ~ California Pest Rating Proposal Agrilus planipennis Fairmaire: Emerald ash borer Coleoptera: Buprestidae Current Rating: None Proposed Rating: A Comment Period: 01/25/2021 – 03/11/2021 Initiating Event: On January 14, 2021, the United States Department of Agriculture removed the federal domestic quarantine for emerald ash borer, a pest that is not known to be present in California. It was determined that the resources currently being used for this quarantine would be more effective if directed towards biological control. Emerald ash borer has not been rated. Therefore, a pest rating proposal is needed. History & Status: Background: Adult emerald ash borers reach 14 mm in length and are narrow and metallic blue-green in color. The larvae are white and flattened and reach 32 mm in length (Center for Plant Health Science and Technology). Adult emerald ash borers feed on leaves (including those of ash (Fraxinus spp.) and white fringetree (Chionanthus virginicus), although this is not reported to cause significant damage (Peterson, 2019). Eggs are laid on tree branches or trunks from 2.5 to more than 90 cm diameter (McCullough, 2019). The larvae tunnel into and feed on phloem and outer sapwood. The feeding damage causes dieback and eventual death (in as little as two years) of the tree (United States Department of Agriculture, -- CALIFORNIA DEPARTMENT OF cdfa FOOD & AGRICULTURE ~ 2018). Adult emergence holes have a characteristic D-shape (Center for Plant Health Science and Technology). Development requires one to two years depending on climate; the larva is the overwintering stage in both cases (Herms and McCullough, 2014).

The Tropical Madrean Flora of Yécora, Sonora, Mexico
Van Devender, T.R. and A.L. Reina-Guerrero. 2016. The Tropical Madrean flora of Yécora, Sonora, Mexico. Phytoneuron 2016- 7: 1–23. Published 15 January 2016. ISSN 2153 733X THE TROPICAL MADREAN FLORA OF YÉCORA, SONORA, MEXICO THOMAS R. VAN DEVENDER ANA LILIA REINA -GUERRERO GreaterGood.org 6262 N. Swan Rd., Suite 150 Tucson, Arizona 85718 [email protected] & The University of Arizona Herbarium P.O. Box 210036 Herring Hall 1130 East South Campus Drive Tucson, Arizona 85721 ABSTRACT The Municipio de Yécora is in the Tropical Madrean zone of the Sierra Madre Occidental in eastern Sonora, Mexico. The flora is very diverse with 1777 taxa in 150 families and 687 genera. The most important families and genera are Asteraceae (14.5% of the flora), Poaceae (11.3%), and Fabaceae (10.6%), Muhlenbergia (38 taxa), Euphorbia (31 taxa), Cyperus (29 taxa), Ipomoea (26 taxa), Quercus (23 taxa including 7 hybrids), and Dalea (22 taxa). Herbaceous plants dominate the flora (71.3%). Twenty-one species in the Yécora flora have protection in NOM-059-SEMARNAT- 2010. Non-native species are 6.2% of the flora but only buffelgrass ( Pennisetum ciliare ) in the tropical lowlands and Natal grass ( Melinis repens ) in grassland and oak woodland are invasive in natural habitats. Vegetation is zoned from foothills thornscrub and tropical deciduous forest in the lowlands to oak woodland and pine-oak forest in the uplands. Plant species diversity increases with elevation and rainfall, peaking in pine-oak forest. The Yécora flora in the Madrean Tropical Madrean zone serves as a baseline to evaluate Madrean affinities in floras in the Madrean Archipelago in northeastern Sonora and southeastern Arizona.

Ecology of Old-Growth Forests in Chihuahua, México
THE TREASURE OF THE SIERRA MADRE: ECOLOGY OF OLD-GROWTH FORESTS IN CHIHUAHUA, MÉXICO By Citlali Cortés-Montaño A dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Forest Science Northern Arizona University December 2011 Approved: Peter Z. Fulé, Ph.D., Chair Ernesto Alvarado-Celestino, Ph.D. Tina J. Ayers, Ph.D. Margaret M. Moore, Ph.D. José Villanueva-Díaz, Ph.D. Abstract THE TREASURE OF THE SIERRA MADRE: ECOLOGY OF OLD-GROWTH FORESTS IN CHIHUAHUA, MÉXICO By Citlali Cortés-Montaño Old-growth forests are valuable but declining worldwide. México still holds large areas covered by temperate forests in the mountains of the Sierra Madre Occidental, but few of these retain old-growth characteristics. These forests provide habitat for Thick- billed Parrots (Rhynchopsitta pachyrhyncha: Psittacidae; “guacamaya”), a CITES-listed endangered species. We studied four old-growth remnants in Mesa de las Guacamayas, a site in the Sierra Madre Occidental in Chihuahua, México, to assess the composition, structure, and age characteristics of the overstory, relating it to fire histories and continental and regional climatic data. We linked our findings to the habitat needs of Thick-billed Parrots reported by the literature, and we studied the β-diversity of the understory plant communities at these sites and related them to the composition, cover, density and fire regimes of the overstory. We found that frequent disturbance by surface fires appears to have contributed to maintaining open, diverse, and productive forests for at least 250 years. While climate was a historical driver of the fire regimes in this mountain range, humans appear to have played a role in the fire regime interruptions of the second half of the 20th century.

The Status of Fraxinus Papillosa (Oleaceae): Sem Study of Epidermal Features
14 LUNDELLIA DECEMBER, 2010 THE STATUS OF FRAXINUS PAPILLOSA (OLEACEAE): SEM STUDY OF EPIDERMAL FEATURES Justin K. Williams1 and Guy L. Nesom2 1Department of Biological Sciences, Sam Houston State University, Huntsville, TX 77341-2116 22925 Hartwood Drive, Fort Worth, TX 76109, USA www.guynesom.com Abstract: The abaxial leaf surfaces of Fraxinus in the southwestern USA and northwestern Mexico are sometimes white-glaucous and have been describedas ‘‘papillose.’’ Individuals exhibiting this morphology have been identified as F. papillosa, a species reported from Arizona, New Mexico, Texas, and Mexico. In the original description of F. papillosa, its leaf epidermal structure was compared to F. americana L., but the abaxial surface morphology of F. papillosa is distinctly different from that of F. americana. In the latter, a cuticular reticulum overlays the epidermis and partially obscures it, while the abaxial surface of F. papillosa is similar to that of F. velutina in its lack of a cuticular overlay. In F. papillosa each epidermal cell is abruptly convex or folded upward into a papilla-like structure, compared to the relatively flat-surfaced cells of F. velutina—intergradation occurs but whether the two are appropriately considered conspecific remains to be determined. SEM photographs of the abaxial leaf surface morphology of F. papillosa, F. velutina, and other species that are similar to F. papillosa are provided.

Merging Science and Management in a Rapidly
Preliminary Assessment of the Moth (Lepidoptera: Heterocera) Fauna of Rincon de Guadalupe, Sierra de Bacadéhuachi, Sonora, Mexico John D. Palting Department of Entomology, University of Arizona, Tucson, Arizona Abstract—The Sierra de Bacadéhuachi is a poorly sampled extension of the Sierra Madre Occidental (SMO) located in east-central Sonora near the town of Bacadéhuachi. Sampling of moths using mercury vapor and ultraviolet lights occurred in summer and fall 2011, and spring 2012 at Rincón de Guadalupe, located in pine-oak forest at 1680 m elevation. Approximately 400 taxa of moths were identified from this locality. Species occurrences demonstrate connections to the famously diverse Yécora area, to the higher, more me- sic SMO in Chihuahua, as well as the Rocky Mountains to the north. Several unidentified and presumably new moth species from Rincón de Guadalupe await further study and description. Two species previously known only from the type specimens (destroyed in WWII) were rediscovered at Rincón de Guadalupe. A complete list of the moths identified from Rincon de Guadalupe is available as a Research Species List in the Madrean Archipelago Biodiversity Assessment (MABA)/Southwest Environmental Information Network (SEINet) online database (Madrean.org). Introduction Bacadéhuachi are Asteraceae (54 taxa), Fabaceae (47 taxa), and Poaceae (36 taxa) (Van Devender and others, Preliminary Flora of The Sierra de Bacadéhuachi is considered the westernmost mas- the Sierra Bacadéhuachi, Sonora, Mexico, this volume). sif of the Sierra Madre Occidental (SMO), and is located east of the Pueblo de Bacadéhuachi, Municipio de Bacadéhuachi, Sonora.

Native Plants for Northern Arizona Landscapes Draft A
NATIVE PLANTS FOR NORTHERN ARIZONA LANDSCAPES DRAFT A Janice Busco, Horticulturist Cheryl Casey, Assistant Horticulturist Copyright July 27, 2000 The Arboretum at Flagstaff 4001 South Woody Mountain Road Flagstaff, AZ 86001 (520) 774-1442 www.thearb.org 1 HOW TO PRACTICE ENVIRONMENTAL HORTICULTURE Environmental horticulture utilizes an understanding and awareness of your site and the native plants available to you and the landscape features and gardening techniques which will collect and preserve water resources. This approach allows for both natural reproduction of plants and their establishment in the landscape. 1. Know your site, its seasonal fluctuations, natural weather cycles and microclimates. 2. Know the plants and features already present on your site. 3. Use water harvesting techniques—cistern, channeling and contours, planting rings, low spots, etc. 4. Use rocks and mulches to conserve and collect water. 5. Use some higher-water using plants to create shade and create protected zones of higher humidity. 6. Visit natural areas with like microclimates to your site and see how, where and in what combinations native plants occur. Look at native plant gardens and see what you like and what works. Once you know your site and its microclimates, you can use native plants from many different habitats in your landscape. 7. Create a healthy, open soil. Use organic soil amendments such as compost and composted manure tilled into the soil to create an open soil, which will allow water to enter. Organic matter will also help cindery and excessively drained soils hold water. 8. Plant with the seasons. Usually, this means waiting for the monsoon season.
