For characterization of seed, different parameters like shape, size, base, apex, surface were considered. For the study of seedlings, the parameters like germination pattern, root, hypocotyl, number of paracotyledons, number and nature of first leaf and subsequent leaves have been characterized. The seed and seedling characters as studied in this investigation are important as taxonomic markers for identification purpose.

    Why Are Coast Redwood and Giant Sequoia Not Where They Are Not?1

    Proceedings of the Coast Redwood Science Symposium—2016 Why Are Coast Redwood And Giant Sequoia Not Where They Are Not?1 2 W.J. Libby Abstract Models predicting future climates and other kinds of information are being developed to anticipate where these two species may fail, where they may continue to thrive, and where they may colonize, given changes in climate and other elements of the environment. Important elements of such predictions, among others, are: photoperiod; site qualities; changes in levels and yearly patterns of temperature, wind, fog and precipitation; the effects of these on interactions with other biota at each site; the effects of changes in fire frequency and intensity; the availability of seeds and seed vectors; and the effects of human activity. Examples are presented, with focus on fire and human activity. Natural migration may need assistance. Establishing groves far from the native ranges is advocated. Keywords: assisted colonization, assisted migration, climate change, fire, Sequoia, Sequoiadendron When preparing this talk and then paper, it became increasingly clear that it is more of an Op-Ed than a comprehensive review, and is meant for people interested in and familiar with coast redwood (Sequoia sempervirens (D. Don) Endl.) and giant sequoia (Sequoiadendron giganteum (Lindl.) Buchholz). Thus, four background references are provided, and they in turn provide detail on many of the topics covered. The final two references provide background on future speculative scenarios. Possible responses to such future scenarios are suggested. Coast redwood’s current natural latitudinal range begins with discontinuous canyon-bottom populations near the southern Monterey County border, extends north through increasingly- continuous coastal and generally-separated interior populations, and stops just north of the Oregon/California border.

  • Density Effects on Giant Sequoia (Sequoiadendron Giganteum) Growth Through 22 Years: Implications for Restoration and Plantation Management

    Density Effects on Giant Sequoia (Sequoiadendron Giganteum) Growth Through 22 Years: Implications for Restoration and Plantation Management

    Density Effects on Giant Sequoia (Sequoiadendron giganteum) Growth Through 22 Years: Implications for Restoration and Plantation Management Robert A. York, Kevin L. O’Hara, and John J. Battles Giant sequoia were planted at various densities and tracked for 22 years to quantify the effect of growing space on diameter, height, stem volume, branch diameter, and branch density. Beginning after just 4 years and continuing through year 22, both stem diameter and height growth were highly sensitive to initial planting density (expressed in this case as horizontal growing space per tree) within the tested range of 3.7 to 28.4 m2. Through 22 years, treatments allocating the greatest growing space per tree had greater volume per tree with no tradeoff yet observed in stand level volume growth. Branch diameter along the stem generally increased with growing space, but branch density did not change. To meet objectives, this study demonstrates that management strategies should be tailored to species’ specific growth strategies. Giant sequoia is characterized by rapid early growth coupled with exceptionally low mortality, which has relevance in both native grove restoration as well as plantation management contexts. The measurements in this study suggest either planting at low density ABSTRACT or thinning giant sequoia very early in dense stands if the objective is to increase individual tree growth rates without a corresponding reduction in stand volume. Young stands developing following high-severity fires may benefit from low-severity prescribed burns if objectives are to increase average stem growth or the rate of canopy recruitment.

    26 Extreme Trees Pub 2020

    Publication WSFNR-20-22C April 2020 Extreme Trees: Tallest, Biggest, Oldest Dr. Kim D. Coder, Professor of Tree Biology & Health Care / University Hill Fellow University of Georgia Warnell School of Forestry & Natural Resources Trees have a long relationship with people. They are both utility and amenity. Trees can evoke awe, mysticism, and reverence. Trees represent great public and private values. Trees most noticed and celebrated by people and communities are the one-tenth of one-percent of trees which approach the limits of their maximum size, reach, extent, and age. These singular, historic, culturally significant, and massive extreme trees become symbols and icons of life on Earth, and our role model in environmental stewardship and sustainability. What Is A Tree? Figure 1 is a conglomeration of definitions and concepts about trees from legal and word definitions in North America. For example, 20 percent of all definitions specifically state a tree is a plant. Concentrated in 63% of all descriptors for trees are four terms: plant, woody, single stem, and tall. If broad stem diameter, branching, and perennial growth habit concepts are added, 87% of all the descriptors are represented. At its most basic level, defining a tree is not species based, but is a structural definition. A tree is represented by a type of plant architecture recognizable by non-technical people. The most basic concepts for defining a tree are — a large, tall, woody, perennial plant with a single, unbranched, erect, self-supporting stem holding an elevated and distinct crown of branches, and which is greater than 10 feet in height and greater than 3 inches in diameter.
  • Two Distinct Himalayan Cypress Species Cupressus Tortulosa and Cupressus Cashmeriana with Additional Comparison to Cupressus Torulosa

    Two Distinct Himalayan Cypress Species Cupressus Tortulosa and Cupressus Cashmeriana with Additional Comparison to Cupressus Torulosa

    Bull. CCP 3 (3): 99-115. (12.2014) D. Mаеrki Two distinct Himalayan cypress species Cupressus tortulosa and Cupressus cashmeriana with additional comparison to Cupressus torulosa In a previous article (Mаеrki 2013b), the trees grown in France, Italy and Switzerland under the label Cupressus cashmeriana Carrière were investigated. It was discovered that the cypresses grown in France are different from those cultivated in Italy, which better match the material collected by Griffith in Bhutan and described by him under the name Cupressus tortulosa. A summary of the main differences has been proposed (Mаеrki, 2013b: 49-50) together with analysis of Carrière’s protologue (1867) and discussion of the correct origin of the French plants in “Tibet” (now Arunachal Pradesh in India). The scope of the present article is to detail these differences with new observations and statistical data. Cupressus torulosa D.Don, Cupressus tortulosa and Cupressus cashmeriana are all growing west to 1 east on the southern slopes of the Himalaya in well separated distribution ranges ; west Nepal, and Himachal Pradesh and Uttarakhand in India, for C. torulosa, Bhutan for C. tortulosa and Arunachal Pradesh (India) for C. cashmeriana. All populations of each species are scattered in different valleys. It is quite likely that the compartmentalisation of these populations over several millions years allowed speciation processes from a common ancestor. There are also lots of planted trees near temples, monasteries and fortresses whose origins are not recorded. Several wild stands are very difficult to access, sometimes almost impossible above high cliffs, and are still in need of investigation; further taxa could possibly yet be discovered.

On 1 May 2009 a GPS census starting at the head of Hall Canyon revealed both in the canyon and upslope beyond it at least 157 individuals in the vicinity of the Black Mountain Trail, plus an outlier 450 m distant near the summit. This species alien to southern California is regenerating prolifically on Black Mountain, as revealed by multiple age classes, from juveniles (seedlings and saplings) about 20– 60 cm tall to young adult trees over 6 m tall, up to about 40 years old, and reproductively mature.
