Modern accumulative and deflation forms of a coastal eolian relief on the sea coast of Kuronian and Vistula Spits are considered. It is established that on coastal barriers there are at the same time processes of accretion and degradation of a dune ridge and leaned against it foredune. Alternation of stable and erosive sites of a dune ridge is revealed. The last has destruction signs as with sea (wave erosion), and from the land side where the whirls of a wind stream creating numerous deflation basins in dune ridge have great value.

AbstractBark characteristics are not only used in the forest-wood supply chain, for example to calculate standing volumes, but also to transform wood volumes and masses. In this study, bark thickness, bark volume and bark mass were analyzed on the basis of 150 Scots pine discs, with a mean diameter of 13 cm. The mean double bark thickness was 3.02 mm, the mean bark volume proportion was 5.6% and mean bark mass proportion was 3.3%. Bark proportions were significantly affected by the log-specific variables ‘diameter over bark’, ‘proportion of bark damage’ and ‘double bark thickness’.

Forest Growth And Yield

The province of Ontario holds approximately 70.2 million hectares of forests: about 17% of Canada’s and 2% of the world’s forests. Approximately 21 million hectares are managed as commercial forests, with an annual harvest in the early part of the decade approaching 200 000 ha. Yield tables developed by Walter Plonski in the 1950s provide the basis for most wood supply calculations and growth projections in Ontario. However, due to changes in legislation, policy, and the planning process, they no longer fully meet the needs of resource managers. Furthermore, Plonski`s tables are not appropriate for the range of silvicultural options now practised in Ontario. In October 1999, the Canadian Ecology Centre- Forestry Research Partnership (CEC-FRP) was formed and initiated a series of projects that collectively aimed at characterizing, quantifying and ultimately increasing the economically available wood supply. Comprehensive, defensible, and reliable forecasts of forest growth and yield were identified as key knowledge gaps. The CEC-FRP, with support from the broader science community and forest industry, initiated several new research activities to address these needs, the results of which are outlined briefly in this paper. We describe new stand level models (e.g., benchmark yield curves, FVS Ontario, stand density management diagrams) that were developed using data collected from permanent sample plots and permanent growth plots established and remeasured during the past 5 decades. Similarly, we discuss new height–diameter equations developed for 8 major commercial tree species that specifically account for stand density. As well, we introduce a CEC-FRP-supported project aimed at developing new taper equations for plantation grown jack pine and black spruce trees established at varying densities. Furthermore, we provide an overview of various projects undertaken to explore measures of site productivity. Available growth intercept and site index equations are being evaluated and new equations are being developed for major commercial tree species as needed. We illustrate how these efforts are advancing Ontario’s growth and yield program and supporting the CEC-FRP in achieving its objective of increasing the supply of fibre by 10% in 10 years while maintaining forest sustainability.

Information is limited regarding the development of early industries along Lake Erie's northeastern shore of the Connecticut Western Reserve. With the opening of the Ohio Country, farmers and pioneer industrialists found the virgin land abundant with natural resources and ready to be exploited. Evidence derived from a rescue excavation of a stone structure at the outlet of the Cowles Creek together with documents established the presence of a lime burning industry. Early settlers found a plentiful wood supply located on the mainland which provided the necessary fuel for burning limestone mined on Cunningham (Kelleys) Island and permitted the construction of shops for use on Lake Erie. Some of the ships that were constructed locally were used to transport lime for the industry. The Sandusky Bay Islands eventually became a rich source of limestone for the expanding American consumer market.
