"Coconut Killer"

Scientist wages war on Far North's coconuts - by Daniel Bateman

COCONUT palms may be ­symbols of the tropics to many, but a scientist says they are damaging the natural environment and may help spread dengue fever.

Cape Tribulation Tropical Research Station director Dr Hugh Spencer has spent the past six years studying the impact the palms have had on native beach vegetation.

He has found the thin 50-100m line of forest that lies between the reef and rainforest - called the littoral zone - is constantly under siege from coconut palms, which edge out native trees, pounding them into submission by constantly dumping fronds and fruit on them. Coconuts that are left to rot on the ground collect water, providing perfect breeding grounds for the dengue-carrying mosquito.

To prevent the palms from conquering the beachfront at Cape Tribulation, Dr Spencer and a small group of volunteers have been regularly removing juvenile palms the only way they know - by hand.

Where there used to be entire groves, native plants such as pandanus and she-oaks are slowly reclaiming the beach. "We're getting very, very good recruitment of natural vegetation," Dr Spencer said. "We've literally removed thousands of coconuts. We're all volunteers. Nobody gets paid in this place. "It basically means that we are protecting and recovering the most endangered of our forest types."

Cairns Regional Council general manager infrastructure services Ross McKim said the council did not have a policy either. But it did have a duty of care denutting palms to reduce the risk of liability. "Council is aware that the removal of coconut palms can be an emotive issue and actively manage the trees that are featured along the foreshores and parks of the region," Mr McKim said.

"Council undertakes denutting and palm frond removal and manage those trees already in place, rather than remove what trees are currently there. "While we are aware that these plants may not be native to Australia, council appreciates these palms play an important part in creating the tropical feel of the region."

Dr Spencer previously took more direct action to eliminate palms from the beachfront by boring holes in a number of palms and poisoning them. The actions angered other locals, who referred to him as a "coconut killer". Dr Spencer said his relationship with his critics appeared to have simmered. "I kind of get the feeling that there is more of a mood of acceptance that they really are a problem," he said. "I get the feeling that is starting to filter though, but I don't have any proof".  "I'm not having many people getting their knickers in a twist about coconuts being removed any more."

Spicata Coconuts in the Palmetum

Here is the background to the spicata dwarfs in the Townsville Palmetum. By Mike Foal - www.cocosplit.com

In my role as an agronomist located in the Russell Island group of Solomon Islands to work in the Joint Coconut Research Scheme (JCRS) funded equally by the Solomons colonial government and Unilever I visited the Polynesian island of Rennell (200 km south of Guadalcanal) by small government vessel in September 1964. While purchasing seed-nuts of the indigenous Rennell Tall population (for a variety trial and despatch to other research centres around the world) from village groves scattered on Rennell, I noticed a "village dwarf" (delicate dwarf palm with orange fruit) that had the "Spicata" character. Each inflorescence of such palms comprises a single branchless stalk in contrast of the normal inflorescence that might have 12 or more branches connected to the main stem. The Spicata inflorescence has many female flowers extending from the base almost to the end of the stalk and a small number of male flowers at the end.

At that time we had begun generating hybrids at the JCRS and were interested in the fact that a Spicata inflorescence produces very little pollen. We could see that an inflorescence with 12 branches would bear at least 12 times more pollen that a Spicata inflorescence. A low pollen producer would be far more likely to outcross and so a high proportion of seeds from a Spicata palm surrounded by non-Spicata would be natural hybrids, whereas non-Spicata dwarf palms, being mostly self-pollinating, would require expensive male flower removal to force hybridisation.

So we collected some seed-nuts from this palm and planted a group of them on the research station. Since that time we realised that the Spicata gene, a mutant that appears rarely but is known in some other countries, is actually a dominant gene, so that any progeny will display the trait even when hybridised with a non-Spicata palm.

Seed-nuts of Spicata orange dwarf were imported from the JCRS (Solomons) palms by the Townsville City Council in 1998 and established in the Palmetum. Several of the palms from these seeds are true Spicata dwarf and some are evidently hybrids as the dwarf character is modified and the orange colour (a recessive gene) is not expressed.

It seems to me that the attractive fruit colour, the delicate dwarf from, and the unusual inflorescence stalk make the Spicata dwarf an ideal ornamental palm.

Extra Virgin Coconut Oil - Food for Life

Cactus Island Nursery has partnered up with Nature Pacific to bring you the very best in Coconut Oil Products: Banaban Extra Virgin Coconut Oil. Coconut Body Butters, Coconut Cooking Oil, Coconut Massage Oil, Coconut Oil products for your Pets, even Coconut Jig Jig Oil! For a look at all Nature Pacific's great products, just click on the banner below.

Coconuts aren't called the 'Tree of Life' for no reason; their nutritional and health benefits are endless. Not only has coconut oil anit-microbial and anti-viral properties, it is also packed full off medium chain fatty acids, which actually help you lose weight! A statement from Paul Richardson, the inventor of Cocotap "I have to live in the tropics, after years of coconut oil consumption I now have no blubber left".... Medium chain fatty acids speed up your body's metabolism, helping you burn calories. Coconut oil contains a unique form of saturated fat, which improves digestion, strenghtens your immune systems, and protects you against infections.

Look for the proper, unrefined coconut oil, such as the Banaban Extra Virgin Coconut Oil. Do not use the the hydrogenated oils. Hydrogenated oil can actually raise cholesterol levels.

As stated by the Nature Pacific website:

Premium Virgin Oil is extracted from fresh organically grown Fiji coconuts with the least amount of processing so that the natural vitamin E, antioxidants and fresh coconut "essence" are retained.

Nutritional Benefits
* Easy digestibility and absorbable
* Contains Vitamin E
* Composed mainly of short and medium chain fatty acids which have desirable qualities and functions
* Does not contain cholesterol
* Reduced fat accumulation in body
* Easily oxidized and therefore a preferred energy source
* Requires no transport system to absorb, digest and metabolize
* Very low content of Omega 6 fatty acid
* Helps maintain healthy ratio of Omega 6 to Omega 3 fatty acids when consumed as a part of diet
* Rich content of lauric acid, the source of disease fighting fatty acid derivative monolaurin
* Contains 6-8 per cent monounsaturated oleic acid
* Inhibitory effect against certain chemical carcinogens
* Superior antigenotoxic activity

Studies undertaken by the Biochemistry Department, University of Kerala showed that coconut oil:
* Does not elevate blood total cholesterol
* Increases blood HDL cholesterol
* Consumed along with coconut kernel lowers blood cholesterol
* Does not elevate LDL cholesterol or LDL cholesterol/HDL cholesterol ratio
* Decreases serum triglycerides

The recommended therapeutic dose of coconut oil is 3-4 tablespoons a day. So little for so many benefits!
