Back when they were the Newlyweds, Jessica Simpson and Nick Lachey also made the rounds at Royal Plantation. True to form, the shopping-crazed Simpson indulged in some local retail therapy. We had a local bazaar with products indigenous to Jamaica, says Royal Plantation managing director Jaime Stewart. Jessica spent 800 just like that The couple also indulged in the resort s C-Bar, a champagne-and-caviar hot spot where the Veuve Clicquot flows freely. .. 

With the exception of one of the studies cited above, very little research has been performed to quantify postharvest residues for thinned stands. None provide this quantification for thinned southern pine plantations. Managers of southern pine timber stands who contemplate the total utilization of the biomass available on their forests have no information on potential postharvest residues available following thinning treatments. 

A number of advantages are evident in the intensive culture of plantations on a short rotation when contrasted to conventional plantation management (18,12). These are ... 

Hardwoods have been preferred for intensive plantation management because of their sprouting capability and the fast growth of these sprouts for the first 10-20 years, as compared to conifers.There are exceptions, however, where conifers may be more desirable. Williford et al. (2Q) reported loblolly pine (Pinus taeda L.) to be superior in biomass production on many sites in the south. Studies by the U.S. Forest Service at Rhinelander, Wisconsin, indicate conifers may have advantages under certain site conditions ( ). For example, jack pine (Pinus banksiana Lamb.) is well adapted to the North, has few serious insect and disease problems, and is less demanding of nutrients and moisture than many hardwoods. 

The aim for tree breeders and forest managers is to define and grow a plantation which will be elastic in its response to the large stresses induced by high wind speeds. Petty Swain (1985) have established models of the stress-strain responses of forest trees which may be used to define the sizes and morphologies of trees, for a defined range of wind speeds and elastic responses. A typical response of a plantation grown spruce tree to wind speed is shown on Fig. 2. This is a classic stress/strain curve, with an... 

These scales of extent define the manner in which the ideas of extreme events are applicable to agriculture and forestry. Wind-throw is a small-scale process and the forest manager must grow and manage plantation forests which will survive extreme wind speeds at the spatial scale of his plantation. The question is, how rare must this extreme event be, before it may be discounted. The answer is likely to be dominated by economics and also the longevity of the plants with a 50 year harvesting interval, it seems clear that the return periods of extreme events up to 50 years (at least) are crucial. 

They had always lived in comfort and where was she to find the money to supply their daily needs Since her father s death and her mother s affliction, they had lived in the utmost seclusion. The few friends of her earlier life had drifted away one by one and there was no one to whom she could turn for help or advice in her hour of need. She must manage alone somehow, she and faithful black Mandy to whom her mother was still the li l Missy of long years ago, the l il Missy of the happy days on the southern plantation. 

As the availability of naturally durable species has declined, the industry has turned to softwoods, and increasingly to softwoods from managed forests or plantations. In order to achieve acceptable longevity under service conditions, it has been necessary to use preservatives to prevent biological attack. Such preservatives have tended to rely upon broad-spectmm biocidal activity and have become very common, particularly for exterior applications. 

A steel blade on a stick offered durability and was a great advancement for both labor and management. Early hoes were forged by plantation blacksmiths or local artisans and were sometimes crafted to the worker s preference. Hand hoeing is seldom used in US sugarcane production. Independent of the costs, the hard work of hoeing, management... 

Additional reasons to manage weeds in ornamental plants and conifer trees include fire protection, frost protection, rodent and disease mitigation, nutrient management, and aesthetics. Uncontrolled weeds and brush become serious fire hazards in the fall or early spring when herbaceous weeds are dry. Plantations of conifers have been lost because weeds were not controlled and fires started. Fires are less destructive when herbaceous vegetation is controlled. 

Such techniques are generally categorized under the term forest vegetation management and involve the use of machinery, fire, and or chemicals during silvicultural practices such as site preparation, weed control for plantation establishment, pine release from overtopping brush, timber stand improvement, etc. 

Between the rows (in the alleyway) it may be possible to intercrop permanently with pasture (sheep), beans or other crops. However, this may be difficult in the case of older plantations where the trees are adapted to a certain type of management in such cases, a step-by-step procedure is recommended (introduction of new crops and elements at yearly intervals), to allow the root systems of the citrus trees to adapt to new competition in the soil. For larger, mechanized organic farms it may be difficult to continue intercropping as soon as the newly planted citrus trees are in production. In such cases, cover crops may be more appropriate in order to avoid disturbances in citrus management. 

Likewise, vanillin is now largely produced synthetically. The world leader in this area is Rhone-Poulenc, which has a unit in Saint-Fons to which was added a unit bought from Monsanto in 1986 on the West Coast of the United States. In the latter plant, vanillin is still extracted from paper pulp liquor. Menthol from plantations in Brazil and China is also produced by synthesis since Haarmann Reimer, bought by Bayer in 1954, managed to carry out industrially the resolution of racemic menthol, thus isolating the levoiso-mer. Anethole, synthesized by Hercules from pine oil, is two to three times cheaper than when it is extracted from star anise.
