Using Prescribed Fire to Regenerate Table Mountain Pine in the Southern Appalachian Mountains
USING PRESCRIBED FIRE TO REGENERATE TABLE MOUNTAIN PINE IN THE SOUTHERN APPALACHIAN MOUNTAINS Patrick H. Brose u.s. Department of Agriculture, Forest Service, Northeastern Research Station, Irvine, PA 16329 Thomas A. Waldrop U.S. Department of Agriculture, Forest Service, Southern Research Station, 223 Lehotsky Hall, Clemson, SC 29634 ABSTRACT Stand-replacing prescribed fires are recommended to regenerate stands of Table Mountain pine (Pinus pungens) in the southern Ap palachian Mountains because the species has serotinous cones and its seedlings require abundant sunlight and a thin forest floor. A 350-hectare prescribed fire in northeastern Georgia provided an opportunity to observe regeneration success at various fire intensity levels. Fires of low and medium-low intensity produced abundant regeneration but may not have killed enough of the overstory to prevent shading. High-intensity fires killed almost all overstory trees but may have destroyed some of the seed source. Medium-high intensity fires may be the best choice because they killed overstory trees and produced abundant regeneration. The forest floor remained thick after fires of all intensities, but roots of pine seedlings were able to penetrate a duff layer of up to 7.5 centimeters thick to reach mineral soil. keywords: fire intensity, Pinus pungens, prescribed fire, southern Appalachian Mountains, Table Mountain pine.

The Toltec Invasion and Chichen Itza

We know a good deal about the events that led to the conquest of Yucatan by these foreigners, and the subsequent replacement of their state by a resurgent but already decadent Maya culture, for we have entered into a kind of history, albeit far more shaky than that which was recorded on the monuments of the Classic Period. The traditional annals of the peoples of Yucatan, and also of the Guatemalan highlanders, transcribed into Spanish letters early in Colonial times, apparently reach back as far as the beginning of the Postclassic era and are very important sources. But such annals should be used with much caution, whether they come to us from Bishop Landa himself, from statements made by the native nobility, or from native lawsuits and land claims. These are often confused and often self-contradictory, not least because native lineages seem to have deliberately falsified their own histories for political reasons. Our richest (and most treacherous) sources are the K’atun Prophecies of Yucatan, contained in the “Books of Chilam Balam,” which derive their name from a Maya savant said to have predicted the arrival of the Spaniards from the east. -

Museo Nacional de Arqueología y Etnología, Guatemala (versión digital). 2 TIKAL, UN SIGLO DE ARQUEOLOGÍA Cristina Vidal Lorenzo "Tikal, un siglo de arqueología" es el título de una exposición monográfica, en la que hemos pretendido reunir las imágenes más representativas del descubrimiento, excavación y restauración de esta importante ciudad de la antigüedad Maya. En realidad, la exposición está concebida como un paseo a través de las intervenciones a las que fueron sometidos sus edificios principales a lo largo de estos últimos cien años. Para ello, hubo que recurrir a las excelentes fotografías tomadas por los incansables exploradores y viajeros del siglo XIX, los primeros que dieron a conocer los vestigios de una ciudad que había permanecido más de mil años sepultada por la selva. Nos referimos a las célebres imágenes captadas por A. Maudslay y T. Maler a finales del siglo pasado, cuyas placas de vidrio originales se conservan en el Museo Británico y en el Museo Peabody de la Universidad de Harvard, respectivamente, No es nuestra intención relatar ahora cómo se llevaron a cabo tales trabajos -información contenida en los paneles explicativos de la muestra- pero sí nos gustaría realizar una pequeña reflexión acerca del impacto que tuvo en la arquitectura de Tikal todo este cúmulo de actuaciones. Deberíamos empezar por su descubrimiento en 1848, ya que con ocasión de esa expedición se cortaron muchos árboles y se despejó parte de la espesa maleza en la que estaban sumergidas las ruinas, con el fin de realizar los primeros dibujos hasta ahora conocidos de Tikal, a cargo del artista Eusebio Lara. -

Maya Ethnobotany Complete Inventory of plants 1 Fifth edition, November 2011 Maya Ethnobotany Complete Inventory:: fruits,nuts, root crops, grains,construction materials, utilitarian uses, sacred plants, sacred flowers Guatemala, Mexico, Belize, Honduras Nicholas M. Hellmuth Maya Ethnobotany Complete Inventory of plants 2 Introduction This opus is a progress report on over thirty years of studying plants and agriculture of the present-day Maya with the goal of understanding plant usage by the Classic Maya. As a progress report it still has a long way to go before being finished. But even in its unfinished state, this report provides abundant listings of plants in a useful thematic arrangement. The only other publication that I am familiar with which lists even close to most of the plants utilized by the Maya is in an article by Cyrus Lundell (1938). • Obviously books on Mayan agriculture should have informative lists of all Maya agricultural crops, but these do not tend to include plants used for house construction. • There are monumental monographs, such as all the trees of Guatemala (Parker 2008) but they are botanical works, not ethnobotanical, and there is no cross-reference by kind of use. You have to go through over one thousand pages and several thousand tree species to find what you are looking for. • There are even important monographs on Maya ethnobotany, but they are usually limited to one country, or one theme, often medicinal plants. • There are even nice monographs on edible plants of Central America (Chízmar 2009), but these do not include every local edible plant, and their focus is not utilitarian plants at all, nor sacred plants. -

Chapter 1 Introduction
Chapter 1 Introduction Chapterl Page 1 1.1 Introduction Chir pine scientifically known as Pinus roxburghii (family Coniferae) is one of the six Pinus species of India and the most widely occurring. It is also known as Himalayan long needle pine, long leaved Indian pine, Indian chir pine, chir or chil. Chir pine (Pinus roxburghii), is the dominant species native of the inter-ranges and principal valleys of the Himalaya. It begins from Afghanistan in the west and ends in Bhutan in the east and extends through countries like Pakistan, India and Nepal. In India its natural forests are found in Jammu and Kashmir, Haryana, Uttarakhand, Himachal Pradesh, and Uttar Pradesh, parts of Sikkim, West Bengal and Arunachal Pradesh. The total area under chir forests is estimated to be 8, 90,000 hectares which occurs between 450 m to 2300 m altitude. It forms pure forests in its habitat but in its upper and lower limits occurs mixed with other conifers and broad leaved species, though rarely, in its upper limits it is found in association with deodar, kail, ban oak, burans (Rhododendron) etc., and in the lower limits with sal, sain, khair, harada, bahera, amla, jamun etc. Besides Chir pine other indigenous pines which are present in Indian subcontinent are P. gerardiana, P. wallichiana, P.kesiya, P.bhutanica, and P.merkusii (Ginwal et.al, 2009), all belong to family Abitaceae or Pinaceae of order coniferals. Classification of Genus Pinus : Kingdom : Plantae Division : Pinophyta Class : Pinopsida Order : Pinales / Coniferals Family : Pinacea/Abitaceae Genus : Pinus The pines have been traced back in the geological history to Jurassic period (150 million years) reaching their climax in the tertiary period (60 million years). -
The Genetic Improvement of Carribbean Pine (Pinus Caribbaea
THE GENETIC IMPROVEMENT OF CARIBBEAN PINE (PINUS CARIBAEA MORELET) - BUILDING ON A FIRM FOUNDATION M.J. Dieters¹ and D.G. Nikles² Abstract:— Pinus caribaea Morelet comprises three geographic varieties or subspecies — var. bahamensis, var. caribaea and var. hondurensis. Variety hondurensis incorporates substantial variation between provenances and individuals within provenance; however for the other two varieties, variation is primarily among individuals. As well, var. caribaea and var. hondurensis especially, have substantial complementarity of characteristics important in commercial plantation forestry. Furthermore, var. hondurensis is the fastest growing of the three varieties, and it has been hybridised successfully with the other two varieties, P. elliottii, P. tecunumanii, and P. oocarpa. Thus genetic improvement of P. caribaea can use and is using the wealth of genetic resources contained in some species of the slash—Caribbean—Central American pines complex. P. caribaea is an important species for commercial plantation forestry throughout the tropics and subtropics, with over 1 million hectares established world-wide. The future of this species (and some of its hybrids) in commercial plantations seems assured. Nevertheless the future of the broad range of genetic resources of P. caribaea that has been assembled through a series of exploration and seed collection efforts, and established in many ex situ plantings, is not assured. The genetic resources of the species has been dispersed across a number of geographic regions and organisations. There is a need to develop a coordinated and collaborative approach to the future conservation and use of the genetic resources that have been collected and developed in ex situ plantings. Keywords: Pinus caribaea, provenance variation, breeding strategy, gene conservation Pinus caribaea Morelet is a very important plantation species. -
Pollen Evidence for Plant Introductions in a Polynesian Tropical Island Ecosystem, Kingdom of Tonga 253
Pollen evidence for plant introductions in a Polynesian tropical island ecosystem, Kingdom of Tonga 253 14 Pollen evidence for plant introductions in a Polynesian tropical island ecosystem, Kingdom of Tonga Patricia L. Fall School of Geographical Sciences, Arizona State University, Tempe, United States [email protected] Introduction The dynamic nature of tropical Pacific ecosystems results from chance migrations and the evolution of founder species, as well as from physical factors such as changes in sea level, ocean currents, tectonic processes and climate (Hope 2001). In addition, this region’s vegetation is constantly adjusting through succession to local perturbations like landslides and tropical cyclones. These ecological and physical processes are compounded by continued immigration of new species, competition, extinctions and extirpation of species. For many island ecosystems the most dramatic impact on species composition results from the arrival of humans and their ‘co-voyaging’ plants and animals (Hope 2001). The degree to which climatic or other natural variations, versus human impacts, have caused recent environmental fluctuations in island ecosystems is an ongoing debate (cf. Nunn 1994; Burney 1997). In this paper, I examine palynological evidence for plants introduced to several islands in the three main island groups of Tongatapu, Ha’apai and Vava’u in the Kingdom of Tonga. My purpose is to briefly document the history of the tropical rainforests of Tonga as they can be reconstructed from pollen cores, to understand the role that humans played in the development of the Tongan flora, and to discuss plant introductions to the islands by both Polynesian and later European settlers. Losses or increases in plant species on remote islands are controlled by many factors, including habitat change, natural factors, and loss of dispersers or pollinators. -
