An Environmental History of the Middle Rio Grande Basin
United States Department of From the Rio to the Sierra: Agriculture Forest Service An Environmental History of Rocky Mountain Research Station the Middle Rio Grande Basin Fort Collins, Colorado 80526 General Technical Report RMRS-GTR-5 Dan Scurlock i Scurlock, Dan. 1998. From the rio to the sierra: An environmental history of the Middle Rio Grande Basin. General Technical Report RMRS-GTR-5. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 440 p. Abstract Various human groups have greatly affected the processes and evolution of Middle Rio Grande Basin ecosystems, especially riparian zones, from A.D. 1540 to the present. Overgrazing, clear-cutting, irrigation farming, fire suppression, intensive hunting, and introduction of exotic plants have combined with droughts and floods to bring about environmental and associated cultural changes in the Basin. As a result of these changes, public laws were passed and agencies created to rectify or mitigate various environmental problems in the region. Although restoration and remedial programs have improved the overall “health” of Basin ecosystems, most old and new environmental problems persist.

The genus includes seven species native to southeastern Asia from Japan and Korea to Taiwan and Hainan, and west through China to northeastern India. Two species are in cultivation in the United States, C. harringtoniaJ (Fig. 1 & 2) of which there are several varieties (one often listed as C. drupacea) , and C. fortunii (Fig. 3). The cultivars are shrubs up to about 20 feet in height; most have broad crowns. The linear and pointed leaves are spirally arranged or in two opposite ranks. The upper sur Fig. 1.

The Role of Fir Species in the Silviculture of British Forests
Kastamonu Üni., Orman Fakültesi Dergisi, 2012, Özel Sayı: 15-26 Kastamonu Univ., Journal of Forestry Faculty, 2012, Special Issue The Role of True Fir Species in the Silviculture of British Forests: past, present and future W.L. MASON Forest Research, Northern Research Station, Roslin, Midlothian, Scotland EH25 9SY, U.K. E.mail:[email protected] Abstract There are no true fir species (Abies spp.) native to the British Isles: the first to be introduced was Abies alba in the 1600s which was planted on some scale until the late 1800s when it proved vulnerable to an insect pest. Thereafter interest switched to North American species, particularly grand (Abies grandis) and noble (Abies procera) firs. Provenance tests were established for A. alba, A. amabilis, A. grandis, and A. procera. Other silver fir species were trialled in forest plots with varying success. Although species such as grand fir have proved highly productive on favourable sites, their initial slow growth on new planting sites and limited tolerance of the moist nutrient-poor soils characteristic of upland Britain restricted their use in the afforestation programmes of the last century. As a consequence, in 2010, there were about 8000 ha of Abies species in Britain, comprising less than one per cent of the forest area. Recent species trials have confirmed that best growth is on mineral soils and that, in open ground conditions, establishment takes longer than for other conifers. However, changes in forest policies increasingly favour the use of Continuous Cover Forestry and the shade tolerant nature of many fir species makes them candidates for use with selection or shelterwood silvicultural systems. -

Torreya Taxifolia
photograph © Abraham Rammeloo Torreya taxifolia produces seeds in 40 Kalmthout Arboretum ABRAHAM RAMMELOO, Curator of the Kalmthout Arboretum, writes about this rare conifer that recently produced seed for the first time. Torreya is a genus of conifers that comprises four to six species that are native to North America and Asia. It is closely related to Taxus and Cephalotaxus and is easily confused with the latter. However, it is relatively easy to distinguish them apart by their leaves. Torreya has needles with, on the underside, two small edges with stomas giving it a green appearance; Cephalotaxus has different rows of stomas, and for this reason the underside is more of a white colour. It is very rare to find Torreya taxifolia in the wild; it is native to a small area in Florida and Georgia. It grows in steep limestone cliffs along the Apalachicola River. These trees come from a warm and humid climate where the temperature in winter occasionally falls below freezing. They grow mainly on north-facing slopes between Fagus grandifolia, Liriodendron tulipifera, Acer barbatum, Liquidambar styraciflua and Quercus alba. They can grow up to 15 to 20 m high. The needles are sharp and pointed and grow in a whorled pattern along the branches. They are 25 to 35 mm long and stay on the tree for three to four years. If you crush them, they give off a strong, sharp odour.

Common Conifers in New Mexico Landscapes
Ornamental Horticulture Common Conifers in New Mexico Landscapes Bob Cain, Extension Forest Entomologist One-Seed Juniper (Juniperus monosperma) Description: One-seed juniper grows 20-30 feet high and is multistemmed. Its leaves are scalelike with finely toothed margins. One-seed cones are 1/4-1/2 inch long berrylike structures with a reddish brown to bluish hue. The cones or “berries” mature in one year and occur only on female trees. Male trees produce Alligator Juniper (Juniperus deppeana) pollen and appear brown in the late winter and spring compared to female trees. Description: The alligator juniper can grow up to 65 feet tall, and may grow to 5 feet in diameter. It resembles the one-seed juniper with its 1/4-1/2 inch long, berrylike structures and typical juniper foliage. Its most distinguishing feature is its bark, which is divided into squares that resemble alligator skin. Other Characteristics: • Ranges throughout the semiarid regions of the southern two-thirds of New Mexico, southeastern and central Arizona, and south into Mexico. Other Characteristics: • An American Forestry Association Champion • Scattered distribution through the southern recently burned in Tonto National Forest, Arizona. Rockies (mostly Arizona and New Mexico) It was 29 feet 7 inches in circumference, 57 feet • Usually a bushy appearance tall, and had a 57-foot crown. • Likes semiarid, rocky slopes • If cut down, this juniper can sprout from the stump. Uses: Uses: • Birds use the berries of the one-seed juniper as a • Alligator juniper is valuable to wildlife, but has source of winter food, while wildlife browse its only localized commercial value. -
Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -

Bunzo Hayata and His Contributions to the Flora of Taiwan
TAIWANIA, 54(1): 1-27, 2009 INVITED PAPER Bunzo Hayata and His Contributions to the Flora of Taiwan Hiroyoshi Ohashi Botanical Garden, Tohoku University, Sendai 980-0962, Japan. Email: [email protected] (Manuscript received 10 September 2008; accepted 24 October 2008) ABSTRACT: Bunzo Hayata was the founding father of the study of the flora of Taiwan. From 1900 to 1921 Taiwan’s flora was the focus of his attention. During that time he named about 1600 new taxa of vascular plants from Taiwan. Three topics are presented in this paper: a biography of Bunzo Hayata; Hayata’s contributions to the flora of Taiwan; and the current status of Hayata’s new taxa. The second item includes five subitems: i) floristic studies of Taiwan before Hayata, ii) the first 10 years of Hayata’s study of the flora of Taiwan, iii) Taiwania, iv) the second 10 years, and v) Hayata’s works after the flora of Taiwan. The third item is the first step of the evaluation of Hayata’s contribution to the flora of Taiwan. New taxa in Icones Plantarum Formosanarum vol. 10 and the gymnosperms described by Hayata from Taiwan are exampled in this paper. KEY WORDS: biography, Cupressaceae, flora of Taiwan, gymnosperms, Hayata Bunzo, Icones Plantarum Formosanarum, Taiwania, Taxodiaceae. 1944).

Woodlands Author: Kerry Dooley Historically the Primary Interest Area for National Inventories Was Timber
Woodlands Author: Kerry Dooley Historically the primary interest area for national inventories was timber. Consequently, the national inventory framework and collection protocols were focused on productive timber- lands (USDA Forest Service 2005). Over time, information such as estimations of carbon sequestration, wildfire fuel loads, and nontimber forest products and services (e.g., biofuels and wildlife habitat) has become topics of increasing interest. The FIA program—the national inventory used in the United States—broadened the focus of its surveys to include non- timberland forests, including woodlands, better aligning with these changing focus areas. Woodlands generally occur in less productive growing condi- tions, such as the arid Southwestern United States. Woodlands provide much, if not all, of the same services provided by forests; that is, they function as important wildlife habitat, improve water quality, serve as carbon sinks (or sources, in the event of wildfires), and provide fuel during wildfire season. The species that comprise woodlands differ in characteristics from most trees. On average, woodland species tend to be slower growing, smaller in stature, and of a form with more forks and branches near the base of the tree. Woodland species often grow as clumps of stems rather than one central stem. Beyond the characteristics of the trees classified as woodland species, specific parameters pertain to classification of the land use category of woodlands, while the Resources Planning Act (RPA) derives calculations of woodland for this report from the FIA data, the FIA and RPA definitions of woodland differ somewhat, as outlined in the following paragraphs. Forest Inventory and Analysis Definitions and Parameters FIA defines woodlands strictly along the lines of species com- position and associated forest types, and considers woodlands a subset of forest lands. -
