2000 houses for Dyer Island Nature Reserve
Dyer Island, near Gansbaai, Western Cape. This is an investment opportunity not to be missed. On Friday night, 24 March 2006, a development of 2000 houses was launched on the Dyer Island Nature Reserve, one of the most sensitive of the Important Bird Areas in South Africa. By the night of the launch 200 (10%) of the houses had already been sold. This development has the approval of Cape Nature.
The houses are for penguins. Because of guano scraping in the past, down to bedrock, most of Dyer Island's penguins are forced to nest on the surface, instead of in burrows. The most highly prized sites on the island are below bushes, and under planks of drift wood. Anything that provides shelter is preferred to an open nest. At surface nests, adults have to be continuously on guard against marauding Kelp Gulls, which sneak in and steal the offspring if the penguin's alertness is disturbed. Surface-nesting penguins are also vulnerable to overheating; if the penguin gets dangerously hot it simply deserts the eggs and goes into the sea to cool off. The gulls immediately take the eggs. Experiments have found the optimal design for the penguin nest boxes and newly installed nest boxes are rapidly occupied by penguins.
The launch of the development coincided with the launch of the Dyer Island Conservation Trust. The housing development is the first "Faces of Need" project of the trust: to raise enough money to install 2000 specially designed artificial burrows for penguins on the isand. Sponsorship is R350 per nest. The banking details are: Dyer Island Conservation Trust, First National Bank Hermanus, Branch code 200412, Current account 621 0020 3497. Your support of this venture will be greatly appreciated.
The founder of the trust is Wilfred Chivell, from whom more details can be obtained. The remaining trustees are Professor Rob Crawford, Ms Angelika Kamp, Mr Newi Makhado and Professor Les Underhill. The trust has several objectives. The most important is the conservation, rehabilitation and protection of the natural environment, including both flora and fauna, in and around Dyer Island. The trust is also concerned about the care of wild animals, especially oiled penguins. The trust will promote educational and training programmes relating to environmental awareness, and greening and clean-up projects. It will also support any research which is related to or supports these objectives. The trust can even provide funds, assets and other resources for similar projects in related areas, for example, at other offshore islands of the Western Cape. The 2000-house development for Dyer Island's penguins is the first of many planned thrusts of the Dyer Island Conservation Trust, to be undertaken in terms of the "Faces of Need" banner.
