Download or read book Developing Ecoregion based Height diameter Models and Reference age Invariant Polymorphic Height and Site Index Curves for Black Spruce and Jack Pine in Manitoba microform written by Wenli Xu and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2004 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight different height-diameter models, five height prediction models with stand variables as predictors and six height and site index models were selected, examined, compared and developed for black spruce (Picea mariana [Mill.] B.S.P.) and jack pine (Pinus banksiana Lamb.) in Manitoba. Eight different height-diameter models were fitted using nonlinear modeling techniques and compared in each of the five ecoregions in Manitoba: Churchill River Upland (Ecoregion 88); Hayes River Upland (Ecoregion 89); Lac Seul Upland (Ecoregion 90); Lake of the Woods (Ecoregion 91); Mid-Boreal Lowland (Ecoregion 148). Results suggested that the Weibull-type and Chapman-Richards models were the most suitable models. Differences of the height-diameter relationship among and between ecoregions were tested. Testing results suggested that height-diameter models significantly differred between ecoregions, indicating ecoregion-based or 'local' height-diameter models are needed for prediction purposes. The ecoregion-based height-diameter models developed in this study may provide more accurate information for developing forest growth and yield models. Five height prediction models were examined with the addition of stand density variables into the base height-diameter model. Adding stand variable resulted in increased prediction accuracy. Six height and site index models were examined and compared for black spruce and jack pine based on the provincial stem analysis data and the most suitable models were selected for Manitoba and the provincial height and site index prediction tables were produced.

Book excerpt: Edinburgh, 1844. Beautiful Aileana Kameron only looks the part of an aristocratic young lady. In fact, she's spent the year since her mother died developing her ability to sense the presence of Sithichean, a faery race bent on slaughtering humans. She has a secret mission: to destroy the faery who murdered her mother. But when she learns she's a Falconer, the last in a line of female warriors and the sole hope of preventing a powerful faery population from massacring all of humanity, her quest for revenge gets a whole lot more complicated. The first volume of a trilogy from an exciting new voice in young adult fantasy, this electrifying thriller blends romance and action with steampunk technology and Scottish lore in a deliciously addictive read.

Book excerpt: Jessica Martin is not a nice girl. As Prom Queen and Captain of the cheer squad, she'd ruled her school mercilessly, looking down her nose at everyone she deemed unworthy. The most unworthy of them all? The "freak," Manson Reed: her favorite victim. But a lot changes after high school. A freak like him never should have ended up at the same Halloween party as her. He never should have been able to beat her at a game of Drink or Dare. He never should have been able to humiliate her in front of everyone. Losing the game means taking the dare: a dare to serve Manson for the entire night as his slave. It's a dare that Jessica's pride - and curiosity - won't allow her to refuse. What ensues is a dark game of pleasure and pain, fear and desire. Is it only a game? Only revenge? Only a dare? Or is it something more? The Dare is an 18+ erotic romance novella and a prequel to the Losers Duet. Reader discretion is strongly advised. This book contains graphic sexual scenes, intense scenes of BDSM, and strong language. A full content note can be found in the front matter of the book.

This book was released on 2009 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report concerns the assessment of potential site productivity for forest planning and in the prediction of forest growth and yield. This was determined using site index (SI) models of young black spruce and jack pines from multiple plantations across Ontario. The equations for these sites were created with varied data of base age specific (BAS), base age invariant (BAI), and dynamic of these species. From here other gauges were given to determine the species models' level of growth and productivity and their variants.--Includes text from document.

Download or read book Developing and Evaluating Tree Height diameter Models at Three Geographic Scales for Black Spruce in Ontario written by and published by . This book was released on 2004 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of the study reported in this paper were to develop tree height-diameter models for black spruce at provincial, regional, & ecoregional scales in Ontario; to compare the different height-diameter relationships among different geographic scales; and to evaluate the consequences & biases resulting from the use of height-diameter models to ecoregions for which they were not parameterized. Results are presented & discussed based on 11,612 black spruce tree measurements made at permanent sample plots across the boreal & central regions of Ontario. The measurements were used to fit the Chapman-Richards growth model at the three scales of interest. The results suggest the presence of significant variations in height-diameter relationships for black spruce among different ecoregions, and indicate the improvement in accuracy achieved when using ecoregion-based height-diameter models as compared to models developed at regional or provincial scales.

This book was released on 1991 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1989 Cieszewski and Bella developed a new, two-coefficient variable-age-site index (VASI) height model for lodgepole pine in Alberta. This model 1) provided compatible site index (SI) and height-growth estimates, and 2) predicted height growth at any age, without prior knowledge of SI, as a function of any other height and corresponding age. The VASI model had fewer coefficients than the previously developed models used for the major tree species in Alberta, and also could predict height with greater accuracy and precision (Cieszewski and Bella 1989)"--Page [1].

Available in PDF, EPUB and Kindle. Book excerpt: Functional forms of equations were derived for predicting 10-year periodic height increment of forest trees from height, diameter, diameter increment, and habitat type. Crown ratio was considered as an additional variable for prediction, but its contribution was negligible. Coefficients of the function were estimated for 10 species of trees growing in 10 habitat types of northern Idaho and northwestern Montana.
