Page 9 LANDA PARK TREE MAINTENANCE PLAN Executive Summary The Landa Park Tree Maintenance Plan is designed to be a tool that can assist in determining needs, scheduling and practices. The need for this plan comes from internal and external customers desiring additional structure and information about the care and maintenance of the trees in Landa Park. It is an effort to inventory, characterize, and formulate systematic management strategies for the significant tree population of Landa Park. The trees of Landa Park require different maintenance regimes depending on the maturity of the trees, the environmental conditions in which they grow and if they are native or planted. Landa Park contains approximately 1,200 trees that have been mapped, studied and managed on a group basis. Park trees, individually and as a group comprise of some of the City’s most valuable specimens in terms of age, aesthetics, environmental and economic benefits, and community impacts. The goal of the Landa Park Tree Maintenance Plan is to: Improve the safety, health and condition of the trees in Landa Park by adhering to ISA best management practices standards of care. Continue the replacement of the trees removed through proper planning and planting. Education and outreach regarding proper tree maintenance, tree benefits, tree protection, and tree specific issues. Landa Park is a well loved park both for the unique environmental features it possesses and the historical nature of the area. It is imperative that the character of the park is maintained within the historical and environmental context, including its trees. HISTORY New Braunfels is located in a unique area of Texas, with two distinct types of ecology –the Blackland Prairie and Edwards Plateau. The Balcones fault line passes through Landa Park creating the aquatic upwelling of the Comal Spring, the largest springs in Texas. This area is located close to the South Texas Plains, which enables an amazing variety of trees-including those of tropical nature –to grow here. In 1941, the New Braunfels Garden Club, assisted by the local Boy Scouts affixed tree identification tags to 37 trees. In 1981, the Guada Coma Garden Club retained botanists to identify the many different species of trees growing in Landa Park. This effort resulted in identification of 54 species in Landa Park. The Landa Park Arboretum was dedicated 1982 and named the Harry Landa Self Guiding Trail. In 2010, the Arboretum trail and guide was revamped to include additional tree species and to improve the navigability of the tree trail. The Arboretum Trail was rededicated to honor the efforts of William and Dolores Schumann in preserving and promoting the unique tree treasures that we have in Landa Park. The City of New Braunfels and the community has a long standing commitment to its trees by maintaining the Tree City USA status in which the efforts of many garden clubs, environmental groups play the main role in the continued obtainment of this honor, often holding the annual community Arbor Day celebration in Landa Park. The City has maintained this designation for the last 26 years. Landa Park Tree Maintenance Plan Page - 1 - Benefits of Trees Trees in urban areas are valued differently than their rural counterparts. Traditional forestry is the management of trees or stands of trees for timber production and other values including wildlife, water quality, and ecological health. Urban Forestry is the management of trees and other forest resources in urban community ecosystems for the environmental, economic, social, health, and aesthetic benefits trees provide society. Urban forest managers can learn from the tradition of woodland forestry in developing systematic approaches to forest management, but they must do so within the context of the very specific benefits that urban trees confer as well as the constraints to maximizing these benefits. For most people the desire to protect and enhance green infrastructure comes from an intrinsic respect for nature and an aesthetic appreciation for parks – park trees provide shade, beauty, educational opportunities, and a link to the past. Urban forests also convey a number of quantifiable public benefits that can be enhanced through management. Trees mitigate air pollution, provide climate control and energy savings, improve soil and water quality, reduce storm water runoff, and increase real estate value. They also provide wildlife habitat and can be a measure of community vitality. And research is beginning to show that some of these benefits of trees can lead to improved public health, especially for those with respiratory ailments. Trees enhance both the physical and spiritual landscape they inhabit. Landa Park Tree Maintenance Plan Page - 2 - Management Goals Urban forests convey a number of quantifiable benefits which can be enhanced through management. The inventory and resource analysis are the preliminary steps to generating specific forest management recommendations. This section outlines the primary goals of this urban forest management plan. A. Canopy Cover and Public Health The foremost goal of this urban forest management plan is to protect and improve tree canopy. The canopy, in the form of individual leaves and their surface area, is the basic structure that provides the bulk of a tree’s environmental and public health benefits. Through transpiration, tree leaves cool the air, reducing ozone formation - a known asthma trigger. Cooler temperatures also lead to a reduction in heat related illnesses (strokes, hypertension and other cardiovascular diseases) as well as a reduction in energy use. Leaves clean the air by absorbing and reducing pollutants including nitrogen oxide, sulfur dioxide, and carbon monoxide. Trees also help by reducing wind speed so that heavy particles settle out. Views of leafy canopies decreased recovery time for hospital patients. Each additional tree and each additional park space improves a city’s air quality and its citizens’ mental and physical health. B. Passive Recreation While healthy trees convey benefits to an entire city, the communities immediately surrounding the park enjoy the majority of benefits. Trees not only improve local air quality, they provide shade for park patrons and a pleasant backdrop of rest and relaxation. Through careful management and planting, trees can create inviting spaces for formal and informal gatherings. C. Aesthetic Values Trees have an inherent aesthetic value. Studies have shown that homes with large trees on their property sell for 10 - 15 percent more than homes in the same neighborhood with few or no trees. In urban areas, property values often increase with street tree health and park area. It is no surprise that many of the highest property values in New Braunfels are found surrounding the nicest parks. Our perception of the seasons is directly related

Climate change vulnerability and adaptation in the Intermountain Region. Gen. Tech. Rep. RMRS-GTR-375. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. Part 1. pp. 1–197. Abstract The Intermountain Adaptation Partnership (IAP) identified climate change issues relevant to resource management on Federal lands in Nevada, Utah, southern Idaho, eastern California, and western Wyoming, and developed solutions intended to minimize negative effects of climate change and facilitate transition of diverse ecosystems to a warmer climate. U.S. Department of Agriculture Forest Service scientists, Federal resource managers, and stakeholders collaborated over a 2-year period to conduct a state-of-science climate change vulnerability assessment and develop adaptation options for Federal lands. The vulnerability assessment emphasized key resource areas— water, fisheries, vegetation and disturbance, wildlife, recreation, infrastructure, cultural heritage, and ecosystem services—regarded as the most important for ecosystems and human communities. The earliest and most profound effects of climate change are expected for water resources, the result of declining snowpacks causing higher peak winter

  • Southern Catalpa Catalpa Bignonioides : the Fish Bait Tree Dr
    Important Tree Species -- Southern Catalpa Catalpa bignonioides : The Fish Bait Tree Dr. Kim D. Coder, Professor of Tree Biology & Health Care, Warnell School, UGA The Southern catalpa (Catalpa bignonioides) tree is a common fixture along roadsides and in old landscapes. The big green leaves and distinctive long dangling fruits are noticeable from hundreds of yards away. Although used in the past for a few wood-based products and pioneer medicines, today catalpa is used for shade trees and for growing a special caterpillar. This catalpa “worm” is prized by fishing enthusiast across the South. Family Ties The catalpa tree is a member of the Catalpa or Trumpet-Creeper family (Bignoniaceae). This family contains more than 700 species scattered around the globe, primarily in tropical and sub-tropical regions. This plant family is represented by trees, shrubs and vines in North America. The trumpet creeper (Campsis radicans), cross vine (Bignonia capreolata), and two catalpa trees (Catalpa ssp.) are the most recognized natives of this family in the Southeastern United States. The exotic Asiatic Pau- lownia tree is a member of this family and has been widely planted, now reproducing on its own. The catalpa genus (Catalpa) has 12 species spread across North America, the Caribbean basin, Eastern Asia and Japan. There are two common native catalpa trees in the United States, and one exotic (Catalpa ovata - Chinese catalpa). Catalpa speciosa is the larger and more northern growing of the two native trees. Common names for this catalpa are Northern catalpa, Western catalpa, and catawba-tree. Catalpa bignonioides is the native Southern catalpa.

  • Interpretations of Cabeza De Vaca's Route
    - Cover: The Great Explorers. I-Cabeca de Vaca in the Desert by Frederic Rem­ ington, 1905. Color halftone, Collier's Weekly (Oct. 14, 1905), 12. Courtesy Frederic Remington Art Museum, Ogdensburg, NY. This study of Cabeza de Vaca was the first of ten Remington illustrations in a series called "The Great Explorers" that appeared in Collier's Weekly between October 1905 and July 1906. According to Peter Hassrick and Melissa J. Webster's Frederic Remington: A Catalogue Raisonne ofPaintings, Watercolors, and Drawings (reviewed on page 261), the original Cabeza de Vaca painting no longer exists. Although Remington's action illustra­ tions irrevocably shaped America's vision of the western lands and peo­ ples, he grew dissatisfied with popular rather than critical acclaim and burned about a hundred of his works in 1907 and 1908 during an at­ tempt to change the course of his career. Nine of "The Great Explorers" series, including the Cabeza de Vaca canvas, were destroyed. An article about the kinds of pinon pine trees Cabeza de Vaca encountered on his route through Texas and northern Mexico begins on page 175. A paper-shell pinon clings to the side of an arroyo in Canon EI Chilpitin, with the Sierra La Gloria range rising in the background. This site is near Monclova, Coahuila, and is on the route of Cabeza de Vaca as projected by Alex D. Krieger. Photograph by Donald W Olson. 175 Pinon Pines and the Route ofCabeza de Vaca DONALD W.
