It showcases evergreen and deciduous oaks as well as relict, monotypic species. This tree walk identifi es trees planted as part of the Learning Landscape as well as other specimens at the school. What is a Learning Landscape? A Learning Landscape is a collection of trees planted and cared for at a school by students, volunteers, and Portland Parks & Recreation (PP&R) Urban Forestry staff. Learning Landscapes offer an outdoor educational experience for students, as well as environmental and aesthetic benefi ts to the school and surrounding neighborhood. Learning Landscapes contain diverse tree species. They are designed to teach students about biology and urban forestry issues, but can also be used to teach geography, writing, history and math, and to develop leadership skills. Community Involvement Community-building is crucial to the success of Learning Landscapes. PP&R works with Urban By involving students and neighbors in Forestry Neighborhood Tree Stewards, teachers, parents, students, and community members to design, the tree planting, the community has plant, establish and maintain these school arboreta. ownership of the trees and a tangible PP&R facilitates this collaboration by working with the school district, neighborhood, students and connection to their school. teachers to create landscapes that meet the need of the individual school community. Tree Planting Experience Learning Landscapes are planted by the school's students under the mentorship of middle or high school students and volunteers. On planting day, tree planting leaders teach students the benefi ts of urban trees, form and function of trees, and tree planting techniques. This leadership aspect of Learning Landscapes gives older students and volunteers the opportunity to connect with their peers, build confi dence, and develop public speaking skills. Involving students and neighbors in the tree planting fosters community ownership of the trees and builds a tangible connection between school and neighborhood. This helps ensure a high tree survival rate by reducing vandalism and encouraging ongoing stewardship of the school's trees. Continued Hands-on Learning Opportunities Once planted, Learning Landscapes are used by teachers and parents for service and leadership projects. Students and teachers continue to build projects around the trees with opportunities to water, prune, weed and mulch. These dynamic landscapes change year after year, depending on student and teacher interests, as new trees are planted and added to the collection. How can I get involved?

  • Birds on San Clemente Island, As Part of Our Work Toward the Recovery of the Island’S Endangered Species
    WESTERN BIRDS Volume 36, Number 3, 2005 THE BIRDS OF SAN CLEMENTE ISLAND BRIAN L. SULLIVAN, PRBO Conservation Science, 4990 Shoreline Hwy., Stinson Beach, California 94970-9701 (current address: Cornell Laboratory of Ornithology, 159 Sapsucker Woods Rd., Ithaca, New York 14850) ERIC L. KERSHNER, Institute for Wildlife Studies, 2515 Camino del Rio South, Suite 334, San Diego, California 92108 With contributing authors JONATHAN J. DUNN, ROBB S. A. KALER, SUELLEN LYNN, NICOLE M. MUNKWITZ, and JONATHAN H. PLISSNER ABSTRACT: From 1992 to 2004, we observed birds on San Clemente Island, as part of our work toward the recovery of the island’s endangered species. We increased the island’s bird list to 317 species, by recording many additional vagrants and seabirds. The list includes 20 regular extant breeding species, 6 species extirpated as breeders, 5 nonnative introduced species, and 9 sporadic or newly colonizing breeding species. For decades San Clemente Island had been ravaged by overgrazing, especially by goats, which were removed completely in 1993. Since then, the island’s vegetation has begun recovering, and the island’s avifauna will likely change again as a result. We document here the status of that avifauna during this transitional period of re- growth, between the island’s being largely denuded of vegetation and a more natural state. It is still too early to evaluate the effects of the vegetation’s still partial recovery on birds, but the beginnings of recovery may have enabled the recent colonization of small numbers of Grasshopper Sparrows and Lazuli Buntings. Sponsored by the U. S. Navy, efforts to restore the island’s endangered species continue—among birds these are the Loggerhead Shrike and Sage Sparrow.

  • IUCN Red List of Threatened Species™ to Identify the Level of Threat to Plants
    Ex-Situ Conservation at Scott Arboretum Public gardens and arboreta are more than just pretty places. They serve as an insurance policy for the future through their well managed ex situ collections. Ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. In situ means "on site", so in situ conservation is the conservation of species diversity within normal and natural habitats and ecosystems. The Scott Arboretum is a member of Botanical Gardens Conservation International (BGCI), which works with botanic gardens around the world and other conservation partners to secure plant diversity for the benefit of people and the planet. The aim of BGCI is to ensure that threatened species are secure in botanic garden collections as an insurance policy against loss in the wild. Their work encompasses supporting botanic garden development where this is needed and addressing capacity building needs. They support ex situ conservation for priority species, with a focus on linking ex situ conservation with species conservation in natural habitats and they work with botanic gardens on the development and implementation of habitat restoration and education projects. BGCI uses the IUCN Red List of Threatened Species™ to identify the level of threat to plants. In-depth analyses of the data contained in the IUCN, the International Union for Conservation of Nature, Red List are published periodically (usually at least once every four years). The results from the analysis of the data contained in the 2008 update of the IUCN Red List are published in The 2008 Review of the IUCN Red List of Threatened Species; see www.iucn.org/redlist for further details.

  • Santa Catalina Island1
    Oak Restoration Trials: Santa Catalina 1 Island Lisa Stratton2 Two restoration trials involving four oak species have been implemented as part of a larger restoration program for Catalina Island. In 1997 the Catalina Island Conservancy began an active program of restoration after 50 years of ranching and farming activities on the island. The restoration program includes removing feral goats and pigs island-wide and converting 80 acres of old hayfields in Middle Canyon to native plant communities. This conversion presented the opportunity to implement experimental restoration trials to test the efficiency and efficacy of a variety of restoration techniques. The primary challenges to restoration in these areas include bison disturbance, deer browsing, long dry seasons and disturbed, weed saturated soils (e.g., Avena fatua, Cynodon dactylon (Bermuda grass), Phalaris aquatica (Harding grass) and incipient populations of Foeniculum vulgare (fennel) and Nicotiana glauca (tree tobacco). In 1999, an island scrub oak seedling trial (Quercus pacifica) was initiated to compare three different watering treatments: 1) a commercial time-release product, Driwater, 2) monthly deep-pipe watering and, 3) unwatered controls. This trial is also a factorial design that includes a native soil component. Soil from beneath mature oaks, potentially containing spore from the oak ectomycorrhizal associate, was added to half the holes at planting time. After two years the seedlings receiving the monthly watering supplements in the deep pipes were significantly taller (p<0.001) than either the no water or Driwater product treatments (45 inches vs. 33 and 29 respectively). Survivorship was higher for the deep pipe treatment (98 percent vs.

  • The Conservation and Restoration of the Mexican Islands, a Successful Comprehensive and Collaborative Approach Relevant for Global Biodiversity
    Chapter 9 The Conservation and Restoration of the Mexican Islands, a Successful Comprehensive and Collaborative Approach Relevant for Global Biodiversity Alfonso Aguirre-Muñoz, Yuliana Bedolla-Guzmán, Julio Hernández- Montoya, Mariam Latofski-Robles, Luciana Luna-Mendoza, Federico Méndez-Sánchez, Antonio Ortiz-Alcaraz, Evaristo Rojas-Mayoral, and Araceli Samaniego-Herrera Abstract Islands are biodiversity hotspots that offer unique opportunities for applied restoration techniques that have proven to bring inspiring outcomes. The trajectory of island restoration in Mexico is full of positive results that include (1) the removal of 60 invasive mammal populations from 39 islands, (2) the identifica- tion of conservation and restoration priorities, (3) the active restoration of seabird breeding colonies through avant-garde social attraction techniques, (4) the active restoration of integrated plant communities focusing on a landscape level, (5) applied research and science-based decision-making for the management of inva- sive alien species, (6) the legal protection of all Mexican islands, and (7) biosecurity and environmental learning programs to ensure outcomes are long lasting. Still, there are many complex challenges to face in order to achieve the goal of having all Mexican islands free of invasive mammals by 2030.

TONY KIRKHAM writes about the exceptional collection of wild collected Chinese plants that thrive there 25 years on. 1987 can be remembered in the Dendrological calendar for a number of events in the tree world, particularly the Great Storm in the South-east of England that destroyed over 15 million trees in one night. This storm was a real wakeup call to anyone with even a slight interest in trees and it started a new beginning in the tree world, raising public awareness and generating new planting schemes across the UK. In the same year, in Sonoma Valley, California, Jane Davenport Jansen had a vision that would make significant additions to arboreta across the botanic garden world, and leave a living legacy that is now one of the largest living collections of wild collected temperate Asian plants in North America; it was the creation of Quarryhill Botanical Garden. In 1968, Jane purchased 61 acres in the foothills of the Mayacama Mountains off the Sonoma Highway in Glen Ellen, Sonoma County to be planted with vineyards, but 20 acres of the hillside contained several abandoned stone quarries and in 1987 she decided to create a garden. Unlike many gardens INTERNATIONAL DENDROLOGY SOCIETY GARDENS & ARBORETA that would be planted purely for landscape, aesthetic and floral qualities, Jane had set her sights on something unique to the area that would become her personal drive, a landscape planted with natural source plants derived from her own funded expeditions to targeted countries around the world with an emphasis on the Far East.

  • Molecular Support for a Basal Grade of Morphologically
    TAXON 60 (4) • August 2011: 941–952 Razafimandimbison & al. • A basal grade in the Vanguerieae alliance MOLECULAR PHYLOGENETICS AND BIOGEOGRAPHY Molecular support for a basal grade of morphologically distinct, monotypic genera in the species-rich Vanguerieae alliance (Rubiaceae, Ixoroideae): Its systematic and conservation implications Sylvain G. Razafimandimbison,1 Kent Kainulainen,1,2 Khoon M. Wong, 3 Katy Beaver4 & Birgitta Bremer1 1 Bergius Foundation, Royal Swedish Academy of Sciences and Botany Department, Stockholm University, 10691 Stockholm, Sweden 2 Department of Botany, Stockholm University, 10691, Stockholm, Sweden 3 Singapore Botanic Gardens, 1 Cluny Road, Singapore 259569 4 Plant Conservation Action Group, P.O. Box 392, Victoria, Mahé, Seychelles Author for correspondence: Sylvain G. Razafimandimbison, [email protected] Abstract Many monotypic genera with unique apomorphic characters have been difficult to place in the morphology-based classifications of the coffee family (Rubiaceae). We rigorously assessed the subfamilial phylogenetic position and generic status of three enigmatic genera, the Seychellois Glionnetia, the Southeast Asian Jackiopsis, and the Chinese Trailliaedoxa within Rubiaceae, using sequence data of four plastid markers (ndhF, rbcL, rps16, trnT­F). The present study provides molecular phylogenetic support for positions of these genera in the subfamily Ixoroideae, and reveals the presence of a basal grade of morphologically distinct, monotypic genera (Crossopteryx, Jackiopsis, Scyphiphora, Trailliaedoxa, and Glionnetia, respectively) in the species-rich Vanguerieae alliance. These five genera may represent sole representatives of their respective lineages and therefore may carry unique genetic information. Their conservation status was assessed, applying the criteria set in IUCN Red List Categories. We consider Glionnetia and Jackiopsis Endangered. Scyphiphora is recognized as Near Threatened despite its extensive range and Crossopteryx as Least Concern.
