Why Plant Trees? Trees in an urban area increase quality of life by: Air quality and cleansing - A typical person uses 386 lb. of oxygen per year. A healthy 32 ft. tall ash tree can produce about 260 lb. of oxygen annually. Two of these trees would supply the oxygen needs of a person each year! Improved water quality - The canopy of a street tree intercepts rain, reducing the amount of water that will fall on pavement and then be removed by a storm water system. Heating & Cooling Costs - A mature tree canopy reduces air temperatures by about 5 to 10° F, influencing the internal temperatures of nearby buildings. Trees divert wind in the winter and increase winter-time temperatures. Increased home sales prices - When homes with equivalent features are evaluated, a 6% increase to the value is associated with nearby trees. Soil Stabilization - Tree roots stabilize soil, helping to minimize erosion.

  • Chestnut Growers' Guide to Site Selection and Environmental Stress
    This idyllic orchard has benefited from good soil and irrigation. Photo by Tom Saielli Chestnut Growers’ Guide to Site Selection and Environmental Stress By Elsa Youngsteadt American chestnuts are tough, efficient trees that can reward their growers with several feet of growth per year. They’ll survive and even thrive under a range of conditions, but there are a few deal breakers that guarantee sickly, slow-growing trees. This guide, intended for backyard and small-orchard growers, will help you avoid these fatal mistakes and choose planting sites that will support strong, healthy trees. You’ll know you’ve done well when your chestnuts are still thriving a few years after planting. By then, they’ll be strong enough to withstand many stresses, from drought to a caterpillar outbreak, with much less human help. Soil Soil type is the absolute, number-one consideration when deciding where—or whether—to plant American chestnuts. These trees demand well-drained, acidic soil with a sandy to loamy texture. Permanently wet, basic, or clay soils are out of the question. So spend some time getting to know your dirt before launching a chestnut project. Dig it up, roll it between your fingers, and send in a sample for a soil test. Free tests are available through most state extension programs, and anyone can send a sample to the Penn State Agricultural Analytical Services Lab (which TACF uses) for a small fee. More information can be found at http://agsci.psu.edu/aasl/soil-testing. There are several key factors to look for. The two-foot-long taproot on this four- Acidity year-old root system could not have The ideal pH for American chestnut is 5.5, with an acceptable range developed in shallow soils, suggesting from about 4.5 to 6.5.

  • Fagus Sylvatica (Common Beech)
    Fagus sylvatica Common Beech Fagus sylvatica is a large deciduous tree with smooth grey bark and a broad, spreading crown, leaves are corrugated, broadly elliptic, changing colour from yellow-green in spring, to a rich copper-russet in autumn. Few plants, except fungi, will survive under it due to the close spacing of its foliage which casts a dense shade in the summer. Flowers are small and green which are followed by a bristly fruit called beech mast which are popular with a variety of wildlife. It makes a superb hedge/ screen as its dense green foliage holds well and often the brown leaves of autumn will hang onto the branches until new foliage emerges giving year round screening. The tree is a good choice for woodland or parkland planting. Container Grown Fagus Sylvatica 5/6m Plant Profile Name: Fagus sylvatica Common Name: Common Beech Family: Fagaceae Height: Up to 30 metres Width: Wider than 15 metres Demands: Full Sun / Partial shade Hardy: Sun, frost, and wind resilient Soil: Chalk, Clay, Sand or Loam Foliage: Deciduous (Yellow/Green in Spring, Green in Summer and Russet Brown in Autumn) Fagus sylvatica - Instant Hedging 250 x 60 x 60 Deepdale Trees Ltd., Tithe Farm, Hatley Road, Potton, Sandy, Beds.

  • Sample Planting Grids All Chestnuts in the Planting Must Have Permanent Embossed Numerical Tags for That Planting and Will Be Monitored by That Tag
    Sample planting grids All chestnuts in the planting must have permanent embossed numerical tags for that planting and will be monitored by that tag. The basic module is 6 x 6 ft spacing with a minimum of 20 ft borders. Such plantings allow easy fencing and mowing. Rows and columns need not be continuous nor do they need to be the same length. Mapping should show gaps. Create a simple schematic map of the planting once done. These configurations can be modified in a wide variety of ways but if lengthened in either direction, a depth of a least 3 rows in any dimension should be maintained. Remember that the pines are an early succession planting designed to create early site coverage and encourage upward growth in hardwoods. Their removal will be a first step in thinning. Different configurations will impose other thinning regimens over time: for example, red oaks might be removed in #1 over time if there is high chestnut survival and vigorous growth. These plantings are designed to introduce at least 30 chestnuts on the site. These should represent at least 2‐3 chestnut families, and may include Kentucky stump sprout families. #1.

  • Chestnut Oak Botanical/Latin Name Quercus Montana
    Chestnut Oak Botanical/Latin name Quercus Montana Chestnut Oak owes its name to its leaves, 4”-6” long, looking like those of the American Chestnut. It is a species of oak in the white oak group native to eastern U.S. Predominantly a ridge-top tree in hardwood forests. Also called Mountain Oak or Rock Oak because it grows in dry rocky habitats, sometimes even around large rocks. As a consequence of its dry habitat and harsh ridge-top exposure, it is not usually large, 59’–72’ tall; specimens growing in better conditions however can become large, up to 141’. It is a long-lived tree, with high-quality timber when well-formed. The heavy, durable, close-grained wood is used for fence posts, fuel, railroad ties and tannin. Saplings are easier to transplant than many other oaks because the taproot of the seedling disintegrates as the tree grows, and the remaining roots form a dense mat about three feet deep. It is monoecious, having pollen-bearing catkins in mid-spring that fertilize the inconspicuous female flowers on the same tree. It reproduces from seed as well as stump sprouts. The 1”-1-1/2” long acorns mature in one growing season, are among the largest of native American oaks and are a valuable wildlife food. Acorns are produced when a tree grown from seed is about 20 years of age, but sprouts from cut stumps can produce acorns in as little as three years after cutting. Extensive confusion between the chestnut oak (Q. montana) and the swamp chestnut oak (Quercus michauxii) has historically occurred.

Nac. No. 85 Km. 45, Linares, Nuevo León 67700, México 2Plant Physiology, Agricultural College, Professor Jaya Shankar Telangana State Agricultural University, Polasa, Jagtial, Karimnagar, Telangana, India Abstract The present paper make a synthesis of a comparative leaf anatomy including leaf surface, leaf lamina, petiole and venation as well as wood anatomy of 30 woody species of a Tamaulipan Thorn Scrub, Northeastern Mexico. The results showed a large variability in anatomical traits of both leaf and wood anatomy. The variations of these anatomical traits could be effectively used in taxonomic delimitation of the species and adaptation of the species to xeric environments. For example the absence or low frequency of stomata on leaf surface, the presence of long palisade cells, and presence of narrow xylem vessels in the wood could be related to adaptation of the species to drought. Besides the species with dense venation and petiole with thick collenchyma and sclerenchyma and large vascular bundle could be well adapted to xeric environments. It is suggested that a comprehensive consideration of leaf anatomy (leaf surface, lamina, petiole and venation) and wood anatomy should be used as a basis of taxonomy and drought resistance.

  • Ferns of the National Forests in Alaska
    Ferns of the National Forests in Alaska United States Forest Service R10-RG-182 Department of Alaska Region June 2010 Agriculture Ferns abound in Alaska’s two national forests, the Chugach and the Tongass, which are situated on the southcentral and southeastern coast respectively. These forests contain myriad habitats where ferns thrive. Most showy are the ferns occupying the forest floor of temperate rainforest habitats. However, ferns grow in nearly all non-forested habitats such as beach meadows, wet meadows, alpine meadows, high alpine, and talus slopes. The cool, wet climate highly influenced by the Pacific Ocean creates ideal growing conditions for ferns. In the past, ferns had been loosely grouped with other spore-bearing vascular plants, often called “fern allies.” Recent genetic studies reveal surprises about the relationships among ferns and fern allies. First, ferns appear to be closely related to horsetails; in fact these plants are now grouped as ferns. Second, plants commonly called fern allies (club-mosses, spike-mosses and quillworts) are not at all related to the ferns. General relationships among members of the plant kingdom are shown in the diagram below. Ferns & Horsetails Flowering Plants Conifers Club-mosses, Spike-mosses & Quillworts Mosses & Liverworts Thirty of the fifty-four ferns and horsetails known to grow in Alaska’s national forests are described and pictured in this brochure. They are arranged in the same order as listed in the fern checklist presented on pages 26 and 27. 2 Midrib Blade Pinnule(s) Frond (leaf) Pinna Petiole (leaf stalk) Parts of a fern frond, northern wood fern (p.
