The roots should cover ~75% of the outside of the root ball. • Many people find success planting in fall through early spring, but planting for many species can happen year round. Installation/Maintenance Planting Technique • Dig a hole only as deep as your new root ball but about 2x as wide. • Be sure that the soil level of the plant in the pot is equal to or slightly higher than the soil level in the ground, do not plant it deeper than it was in the nursery pot. • Crumble and backfill the soil around the root ball, gently packing it in to ensure that there are not air pockets. • Soak the new planting thoroughly, soaking the planting hole and the undisturbed soil around it (2-3 ft around the planting). Soak Large Area Base of plant at grade or slightly above Wider hole than root ball Installation/Maintenance Planting Technique • Mulch the new plantings to keep the soil cooler and retain moisture. Mulch should be 2- 3 inches deep around the plant but should not come in contact with the stem of the plant. • Continue watering for the first year, generally every 7-10 days but maybe more or less depending on the species and soil type. • Infrequent, long slow soaks are better than short and frequent watering. • Avoid watering directly against the base of the plant but soak the area around the root zone 2-3’ around the plant. Water by soaking a large area Mulch but avoid mulch touching plant stems Installation/Maintenance Native Plant Maintenance • Weed and mulch! Sometimes natives that self-seed may need to be thinned or weeded out to maintain design or keep other plants from being crowded out. • Watering can be reduced depending on species.

  • Gitksan Plant Classification and Nomenclature
    Journal of Ethnobiology 19(2): 179-218 Winler 1999 GITKSAN PLANT CLASSIFICATION AND NOMENCLATURE LESLIE MAIN JOHNSON Department ofAnthropology, University ofAlberta Edmonton, Alberta, Canada T6G 2H4 ABSTRACT.- The Gitksan of northwestern British Columbia are speakers of an Interior Tsimshianic language. They live in a mountainous, densely forested environment transitional between the Northwest Coast and the Boreal interior plateau. Traditionally the Gitksan pursued a mixed fishing/hunting/ gathering subsistence strategy. The Gitksan have a roughly hierarchical classification of plants. The general domain 'plant kingdom' or 'floral form' is recognized but not overtly labelled. Within this, several broad groupings of the life form sort can be distinguished. Three of these are large groupings composed ofa number of named subordinate generics: gan 'trees,' sgan 'plants,' and maa'y 'berry' or 'fruit plants.' 'Plants' include a diverse mixture of forms ranging from small trees to some perennial herbs, and prostrate sub-shrubs. The 'plant' and the 'berry' groups overlap extensively. The remainder are residual taxa which are empty, containing few or no named subtypes, though encompassing morphological and taxonomically diverse forms: habasxw'grass' or'hay,' 'yens 'leaves' or 'herbaceous plants,' majagalee 'flowers,' umhlw 'moss,' and.gayda ts'uuts 'fungi.' A mixture of morphologic and utilitarian characters seems to underlie the system of plant classification. The relationship of partonomy to utility and classification is explored. Ninety distinct generics have been documented. Eighty-four represent vascular plants and six represent mosses, fungi and lichens. Keywords: classification, Gitksan, ethnobotany, Canada, Northwest Coast RFSUMEN.- Los Gitksan hablan una Iengua tsimsiana interior. Viven en una region montaflosa y de bosques densos.

  • Classification and Description of World Formation Types

Classification and description of world formation types. Gen. Tech. Rep. RMRS-GTR-346. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 222 p. Abstract An ecological vegetation classification approach has been developed in which a combi- nation of vegetation attributes (physiognomy, structure, and floristics) and their response to ecological and biogeographic factors are used as the basis for classifying vegetation types. This approach can help support international, national, and subnational classifica- tion efforts. The classification structure was largely developed by the Hierarchy Revisions Working Group (HRWG), which contained members from across the Americas. The HRWG was authorized by the U.S. Federal Geographic Data Committee (FGDC) to devel- op a revised global vegetation classification to replace the earlier versions of the structure that guided the U.S. National Vegetation Classification and International Vegetation Classification, which formerly relied on the UNESCO (1973) global classification (see FGDC 1997; Grossman and others 1998). This document summarizes the develop- ment of the upper formation levels. We first describe the history of the Hierarchy Revisions Working Group and discuss the three main parameters that guide the clas- sification—it focuses on vegetated parts of the globe, on existing vegetation, and includes (but distinguishes) both cultural and natural vegetation for which parallel hierarchies are provided.

  • Ethnobotanical Studies of Some Useful Shrubs and Trees of District Buner, NWFP, Pakistan
    Ethnobotanical Studies of some Useful Shrubs and Trees of District Buner, NWFP, Pakistan Mohammad Hamayun Address for correspondence: Ethnobotany Project, WWF-Pakistan 34 D/2 Sahibzada Abdul Qayum Road, University Town, Peshawar Tel: 0092-91-841593 Fax: 0092-91-841594 E-Mail M. Hamayun: [email protected] Abstract The present study was carried out to assess and document ethnobotanical knowledge of shrubs and trees of District Buner as the area has diverse flora and high ethnobotanical potential. It was found that 94 different plant species are used for medicinal, timber, fuel wood, fodder, ornamental, agricultural tools, Thatching, fencing, naming (folk lore) and fruit yielding purposes. Bulk of plant species show multiple uses like Juglans regia wood is used for making furniture, gun woody parts, carving and as fuel. Root bark (Dandasa) is used for cleaning and sparkling teeth. Leaves are used by womenfolk for coloring lips (make-up). Nuts are edible and are traded to other parts of the country. The fruits are aphrodisiac and also used as dye. Decoction of leaves is given in eczema and intestinal worms. Used in naming i.e. Ghuz. Several species like Abies pindrow, Berberis lycium, Juglans regia, Skimmia laureola, Daphne oleoides and Pistacea integrima are under severe pressure from local population and require protection and conservation strategies. Key words: Ethnobotany; Medicinal shrubs; Medicinal trees; Buner. Introduction to the Area Buner is located in the north of NWFP, bordering upper Swat on the north, Malakand Agency on the west, Mardan District on the south and Hazara Division on the east. Buner is a Sanskrit word which means forest, which seems to be true because Buner is rich in forestry.

  • Nr 222 Native Tree, Shrub, & Herbaceous Plant
    NR 222 NATIVE TREE, SHRUB, & HERBACEOUS PLANT IDENTIFICATION BY RONALD L. ALVES FALL 2014 NR 222 by Ronald L. Alves Note to Students NOTE TO STUDENTS: THIS DOCUMENT IS INCOMPLETE WITH OMISSIONS, ERRORS, AND OTHER ITEMS OF INCOMPETANCY. AS YOU MAKE USE OF IT NOTE THESE TRANSGRESSIONS SO THAT THEY MAY BE CORRECTED AND YOU WILL RECEIVE A CLEAN COPY BY THE END OF TIME OR THE SEMESTER, WHICHEVER COMES FIRST!! THANKING YOU FOR ANY ASSISTANCE THAT YOU MAY GIVE, RON ALVES. Introduction This manual was initially created by Harold Whaley an MJC Agriculture and Natural Resources instruction from 1964 – 1992. The manual was designed as a resource for a native tree and shrub identification course, Natural Resources 222 that was one of the required courses for all forestry and natural resource majors at the college. The course and the supporting manual were aimed almost exclusively for forestry and related majors. In addition to NR 222 being taught by professor Whaley, it has also been taught by Homer Bowen (MJC 19xx -), Marlies Boyd (MJC 199X – present), Richard Nimphius (MJC 1980 – 2006) and currently Ron Alves (MJC 1974 – 2004). Each instructor put their own particular emphasis and style on the course but it was always oriented toward forestry students until 2006. The lack of forestry majors as a result of the Agriculture Department not having a full time forestry instructor to recruit students and articulate with industry has resulted in a transformation of the NR 222 course. The clientele not only includes forestry major, but also landscape designers, environmental horticulture majors, nursery people, environmental science majors, and people interested in transforming their home and business landscapes to a more natural venue.

  • Native Hawaiian Plants As Groundcovers
    Native Hawaiian Plants as Ground Covers by Gregory A. Koob Many native Hawaiian plants can serve well as ground covers. They work well in a variety of environments, from oceanfront gardens to landscapes up in the mountains and anywhere inbetween. Almost any place a nonnative plant works as a ground cover, there is a native plant that will work just as well. The only ground cover that cannot be replaced with a native plant is lawn grass. And with a little research, that may change some day as well. When choosing native plants for ground covers, take into consideration the natural environment that plant normally occurs in. But don’t let that restrict your thinking. There are many native plants that work as ground covers that come from beach envi- ronments that work very well in the oceanside landscape, often better than non- natives. But many of those plants also work well away from the ocean. I’m not a big fan of using commercial fertilizers with native plants. After all, our na- tive plants evolved with our native soils. But, if your landscape plants are showing signs of nutrient deficiencies, and your soil test recommends adding fertilizers (using orna- mental plants as surrogates for fertilizer rates) then add fertilizer at about half the rec- ommended rates. I’ve seen many native plants that have been “beefed up” with too much nitrogen, at the expense of flowering and resistance to pests, drought and dis- eases. Native plants provide habitat for our native insects. A mixed native landscape will provide the life-history needs of many of our native pollinators.
