DEBATES - Tuesday 27 February 1990 whi ch the Conservation Land Corporation may 1 ea se. Therefore, it has not been able to apply the provision to the Territory Parks and Wildlife Conservation Act, its by-laws and regulations, for the purposes of management of parks or reserves and in accordance with a management plan on such land. This amendment, by enabling declaration of parks and reserves on areas leased by the Conservation Land Corporation, will allow the Territory to declare and manage parks and reserves on Aboriginal land and other lands where lease agreements have been reached. Recently, representations have been received from the combined Abori gi na 1 1 and counc i 1 s regardi ng the management of Abori gina 1 1 and as national parks by the Conservation Commission and requesting an enabli'ng amendment to allow for this to be embodied in the Territory Parks and Wildlife Conservation Act. The amendment will allow also for similar management arrangements on other 1 eased 1 ands. Precedent for thi s action appears in the Commonwealth National Parks and Wildlife Conservation Act, which provides for the declaration of areas of Aboriginal land 'held under lease by the director' in section 7(1)(a). In removing the obstacle to declaration of lands leased for park management purposes, the prospects for conservation management to the mutual benefit of landholders and the Territory are significantly improved. Mr Deputy Speaker, I commend the bill to honourable members. Debate adjourned. OZONE PROTECTION BILL (Serial 264) Bill presented and read a first time. Mr HATTON (Conservation): now read a second time. Mr Deputy Speaker, I move that the bill . be The dep 1 et i on of the ozone protection 1 ayer is of major i nternat i ona 1 concern. Over the last 10 years, there has been growing concern about the release of certain chemicals, mainly chlorofluorocarbons or CFCs and bromofluorocarbons or halons, which are depleting the ozone protection layers of the earth, especially over Antarctica. . The Australian and New Zealand Environmental Council, known as ANZEC, advi sed that these ozone dep 1 et i ng substance s eventua 11 y reach '-'the stratosphere where they break down gradually, releasing halogens which destroy the earth's protective layer. Satellite data collected since 1979 shows global ozone loss at 2.5% plus or minus 0.6% up to 1987, including solar cycle effects. An area of severe depletion in ozone concentration of up to 50% in spring each year has occurred over Antarctica. While thi sis commonly called a 'hole' in the ozone layer, in fact it is an area of severe seasonal depletion. After the hole closes in ear1y'summer, there is some dilution of the ozone layer outside the Antarctic region while ozone moves back to fill the hole, with concentrations returning to near normal levels by summer. The decrease in ozone over Antarctica between 1979 and 1988 has generally been increasing, with the hole becoming progressively deeper each year until 1987. A shallower hole was recorded in 1988 and it is believed that this was due to the warmer temperatures in the stratosphere over Antarctica at that time. Seasonal decreases in ozone levels over southern Australia in 8817
