  • The Collection of Oak Trees of Mexico and Central America in Iturraran Botanical Gardens
    The Collection of Oak Trees of Mexico and Central America in Iturraran Botanical Gardens Francisco Garin Garcia Iturraran Botanical Gardens, northern Spain [email protected] Overview Iturraran Botanical Gardens occupy 25 hectares of the northern area of Spain’s Pagoeta Natural Park. They extend along the slopes of the Iturraran hill upon the former hay meadows belonging to the farmhouse of the same name, currently the Reception Centre of the Park. The minimum altitude is 130 m above sea level, and the maximum is 220 m. Within its bounds there are indigenous wooded copses of Quercus robur and other non-coniferous species. Annual precipitation ranges from 140 to 160 cm/year. The maximum temperatures can reach 30º C on some days of summer and even during periods of southern winds on isolated days from October to March; the winter minimums fall to -3º C or -5 º C, occasionally registering as low as -7º C. Frosty days are few and they do not last long. It may snow several days each year. Soils are fairly shallow, with a calcareous substratum, but acidified by the abundant rainfall. In general, the pH is neutral due to their action. Collections The first plantations date back to late 1987. There are currently approximately 5,000 different taxa, the majority being trees and shrubs. There are around 3,000 species, including around 300 species from the genus Quercus; 100 of them are from Mexico and Central America.

  • Reference Plant List
    APPENDIX J NATIVE & INVASIVE PLANT LIST The following tables capture the referenced plants, native and invasive species, found throughout this document. The Wildlife Action Plan Team elected to only use common names for plants to improve the readability, particular for the general reader. However, common names can create confusion for a variety of reasons. Common names can change from region-to-region; one common name can refer to more than one species; and common names have a way of changing over time. For example, there are two widespread species of greasewood in Nevada, and numerous species of sagebrush. In everyday conversation generic common names usually work well. But if you are considering management activities, landscape restoration or the habitat needs of a particular wildlife species, the need to differentiate between plant species and even subspecies suddenly takes on critical importance. This appendix provides the reader with a cross reference between the common plant names used in this document’s text, and the scientific names that link common names to the precise species to which writers referenced. With regards to invasive plants, all species listed under the Nevada Revised Statute 555 (NRS 555) as a “Noxious Weed” will be notated, within the larger table, as such. A noxious weed is a plant that has been designated by the state as a “species of plant which is, or is likely to be, detrimental or destructive and difficult to control or eradicate” (NRS 555.05). To assist the reader, we also included a separate table detailing the noxious weeds, category level (A, B, or C), and the typical habitats that these species invade.

  • An Updated Infrageneric Classification of the North American Oaks
    Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L.

    ALPINE ZONE The alpine zone occurs in high mountain areas where the mean annual precipitation is above 41 inches and the RET is the lowest in the state (Figure 7.6). These areas occur above the upper timber line. The vegeta- tion consists mainly of small cushion plants on rocky slopes. Elevation Figure 7.6. Monthly distribution of precipitation within the alpine zone contrasted with modeled reference evapotranspiration ranges from 10,800 feet (RET). Extracted from Daymet climate models (Thornton et al., to 13,528 feet above sea level (ASL). Snow tends to persist 1997). in these areas most of the year, and in some areas, snow pack does not disappear, depending on topography and the year. The climate is characterized by long, cold winters and short, cool growing seasons of less than 60 days (Figure 7.7). Even then, frost can occur at any time. Although total annual precipitation is usually over 40 inches, soil water is often in frozen form because the mean annual temperature is well below 32 degrees Fahrenheit. Much of the alpine zone is comprised of steep, barren and exposed bedrock or loose scree and fell fields (72 percent). Some of this is permanent snow and ice (7 percent). Soils usually develop between rocks and in pockets of gentler terrain where fine particles accumulate (Photographs 1 and 2). Figure 7.7.

    Design 2.4 | Landscaping B. Plant List See Appendix A (City of Sedona Approved Landscape Plant List); LDC Section 5.6 (Landscaping) (1) Intent a. The City of Sedona Approved Landscape Plant List (Appendix A) is intended for use by development projects that must comply with the LDC Section 5.6 (Landscaping). b. Residents may use the list as a reference when choosing plants for their home. (2) Purpose The purpose of the Plant List is to apply the Community Plan vision to the landscape component of the built environment, specifically the Sense of Place, Environmental Stewardship, and Sustainability goals. a. Sense of Place The built landscape can and should mirror Sedona’s unique natural environment. Landscaping is an important and very visible component of the built environment, especially in commercial developments seen from the highway. The use of native plants is intended to blend the built landscape with the surrounding natural landscape by incorporating the same plants. b. Sustainability and Water Conservation Maintaining a sustainable environment is a fundamental goal of the community. How this relates to landscaping is the desire for a healthy, diverse, and productive ecosystem that can be sustained over time without depleting or impacting natural, cultural, or economic resources. (3) Listed Plants See Appendix A The Plant List (Appendix A) features plants that are considered water-wise or low water use plants, unless listed as riparian. a. The plant list includes three categories: native, adaptive, and riparian plants. A separate list includes invasive weeds. b. Given the LDC requirement regarding the minimum size of shrubs, the Plant List does not include shrubs or cacti that are typically less than 2’ in height.
