| 2 | PARTICIPATING ORGANIZATIONS |
There are several organizations contributing to the protection and re-establishment of Glossy Black-Cockatoo habitat in South Australia. These include community groups and government departments. There is a broad agreement of aims, and some communication and co-ordination between the groups. However, most are run by volunteers who have little spare time to find out about the activities of others. This directory aims to facilitate co-operation between groups and to inform people planning on becoming involved in Glossy Black-Cockatoo conservation about the type of projects that have been organized. Links between organizations are illustrated in Figure 1. Many private individuals have revegetated their own land, or helped others, without being part of any formal organization (Section 4). This contribution is included in Figure 1. We also acknowledge the contribution of many other groups and individuals to other aspects of Glossy Black-Cockatoo conservation which fall outside the scope of this report, including monitoring, nest protection and education.
| 2.1 | Glossy Black Rescue Fund |
The Glossy Black Rescue Fund was formed on Kangaroo Island in 1993. Its aim is to raise and distribute funds for the protection and rehabilitation of Glossy Black-Cockatoo habitat. Projects have been selected for funding on the basis of their likely contribution to the future conservation of the Glossy Black-Cockatoo. Up until the end of 1997, 22 habitat protection and rehabilitation projects had been completed and funded. These projects include the protection of 327 ha of habitat and revegetation projects totalling 43 ha. Over 7,000 seedlings have been made available free of charge to landholders. Projects from across Kangaroo Island have been approved, with most completed projects being on the Dudley Peninsula, an area where the cockatoos no longer nest, possibly as a result of habitat clearance.
Since 1994, the Glossy Black Rescue Fund has called for submissions through local Landcare Groups. More recently, landholders of areas identified as having specific benefit to Glossy Black-Cockatoos have been directly approached about setting aside areas for habitat regeneration. Information required in an application includes a site description, an outline of the work to be completed and an estimate of the funds required. Before a grant is made, the landholder must lodge an application to have the designated site proclaimed as a Sanctuary (under Section 44 of the National Parks and Wildlife Act 1972; see Section 7).
Projects that assess habitat or contribute to habitat availability are also considered. The Fund has provided financial assistance for the mapping of potential nesting and feeding habitat on western Kangaroo Island and the southern Fleurieu Peninsula, for the material for 80 nest boxes, and for the hire of equipment needed for a study of the effects of soil moisture on seed production in Drooping Sheoak.
The Glossy Black Rescue Fund is administered on Kangaroo Island by a volunteer management committee, and funds are administered through the National Parks Foundation of South Australia. Major sponsors of the fund include the National Landcare Program, Save the Bush, National Parks Foundation of South Australia, Australian Geographic, and the South Australian Ornithologists Association. Kangaroo Island Garden Centre has donated plants for several projects. Many members of the community have also contributed money and time to this organization. The high profile and good management of the Glossy Black-Cockatoo Fund has resulted in the fund attracting continuing government, community and corporate support, and it is likely this group will continue to fund revegetation projects well into the future. The Fund commissioned the current report to enable the targeting of funds into areas that will be of maximum habitat benefit to the Glossy Black-Cockatoo.

| 2.2 | Bird Observers Club of Australia |
The Bird Observers Club of Australia funded one of the first revegetation projects on Kangaroo Island about 16 years ago. It was on Borda Park at the western end of the island, where three plots of between up to 30 Drooping Sheoak were planted. These trees are now about 12 m high. Glossy Black-Cockatoos regularly visit and feed in two of the patches along the Ravine de Casoars. The original trees were well protected with tree guards. However, because stock has had access to these areas, the plots have not been self-regenerating. While the Bird Observer's Club is not presently involved in revegetation, it has been raising money for Glossy Black-Cockatoos on the mainland.

| 2.3 | Department of Environment, Heritage & Aboriginal Affairs |
The Department of Environment, Heritage and Aboriginal Affairs has responsibility for Glossy Black-Cockatoos at many levels. As part of its legislative requirement to protect the cockatoos as an native endangered animal, DEHAA chairs the Glossy Black-Cockatoo Recovery Team and administers research and management contracts approved by the team. It gazetted Lathami Conservation Park and Parndana Conservation Park, at least in part to provide secure habitat for the cockatoos. It is also responsible for over-seeing clearance controls, the declaration of Heritage Areas and the ratification of Sanctuary Agreements, all of which help to protect the Glossy Black-Cockatoo.
Lathami Conservation Park covers an area of about 1,500 ha. This land was purchased by DEHAA to provide habitat security for Glossy Black-Cockatoos, for which it is an important feeding and breeding area. Most of the native vegetation is intact, although it had been used in part for sheep grazing before 1986, and 120 ha of pasture remain. As part of the management plan of the park, DEHAA attempted to revegetate two sections of pasture with Drooping Sheoak in 1990, with the assistance of Parndana Area School and Kingscote Scout Group. Both direct seeding and tube stock were used. However, Western Grey Kangaroos, Brushtail Possums and Tammar Wallabies, which abound within the park, completely devastated the direct seedling trials and caused serious losses to the tube stock. Electric fences have been erected around one of the areas and revegetation efforts will continue over the next few years.

| 2.4 | Landcare - Primary Industries South Australia |
Many landholders on Kangaroo Island have retained remnants of native vegetation on their properties. They recognize that the productivity of the land is dependent on a healthy environment. As a result Kangaroo Island has one of the largest per capita involvements in Landcare in Australia. Landcare groups are coalitions of landholders and other members of the community who wish to contribute to environmental protection and rehabilitation in their local area.
There are 13 Landcare groups, which mostly based on catchments or regions, and cover at least 75% of the farmed areas on the island. The groups are Upper Cygnet, Lower Cygnet, Chain of Lagoons, Eleanor River, South West Kangaroo Island, Middle River, Lake Ada, Penneshaw School and Community, Bugga Bugga Creek, Timber Creek, Emu Bay, Stokes Bay and Eco-Action. Some groups formed in response to emerging land degradation, such as salinization and rising groundwater. All saw the need to protect the native vegetation before problems emerge.
Landcare on the island is facilitated by a Landcare Officer who currently operates out of the Department of Primary Industries and Resources, South Australia (PIRSA). Groups set their own agenda, but specific projects have received federal funding from the Natural Heritage Trust, and state funding through State Revegetation Grants. Projects undertaken so far include management of salinity problems, control of weeds, investigation into perennial grasses, and revegetation and conservation of remnant vegetation.
Many members of Landcare groups have participated in Property Management Planning workshops run by PIRSA. The workshops assist landholders to formulate plans for running the farm, and, as well as covering business management, human resources and enterprise performance, include managing the property's natural resources - the soil, water and vegetation. Aerial photography is used to assist in the identification of remnant vegetation with high conservation potential or areas suitable for revegetation. PIRSA also advises on the appropriate species to be planted. Where Drooping Sheoak is to be planted, landholders are directed to the Glossy Black Rescue Fund for possible financial assistance. There have been many Landcare projects to re-establish Glossy Black-Cockatoo feeding habitat, and while most are less than four years old, the first plantings are now beginning to produce cones and should soon be discovered by Glossy Black-Cockatoos.

| 2.5 | Kangaroo Island Seed Bank / Parndana Area School |
Parndana Area School is home to the Kangaroo Island Seed Bank, a unique, community-based seed-bank established with a grant from Greening Australia in 1994. The seed bank trades in seed of Kangaroo Island’s native plants, including the major tree species (e.g. Sugar Gum Eucalyptus cladocalyx, South Australian Blue Gum Eucalyptus leucoxylon, Manna Gum Eucalyptus viminalis, Messmate Stringybark, Eucalyptus obliqua, and Brown Stringybark Eucalyptus baxteri), small trees and shrubs (e.g. Drooping Sheoak Allocasuarina verticillata, Ti-trees Melaleuca spp., Banksia spp. and Bottle-brush Callistemon spp.), Yaccas Xanthorrhoea semiplana and native grasses. As well contributing to the regeneration of Glossy Black-Cockatoo habitat, seed from the seed bank is used for agroforestry, windbreaks and the revegetation of degraded saline areas and areas damaged by Koalas.
The seed bank operates commercially, with seed being bought, sold or exchanged for seed of a similar value. There is a turnover of about 20 kg per year, with around 20 kg of seed held between seasons. Commercial rates are charged, with prices based on ease of collection. In 1997, Drooping Sheoak was available at $120 per kg and Sugar Gum at $ 210 per kg. Most other species cost between $100 and $180 per kg. Incoming seed is bought or exchanged at 80% of the sale price, making seed collection an attractive fund-raising exercise for community groups.
The collection location of each batch of seed is recorded, and efforts are made to provide revegetation projects with seed from a local source. Drooping Sheoak specifically for Glossy Black-Cockatoo is collected from known feeding trees, mostly from Lathami Conservation Park under permit. Being more difficult to collect because of the height of the trees, Sugar Gum seed is collected opportunistically from around the island. About 8 kg of Drooping Sheoak has been provided for revegetation projects across the island, about half of this going to Glossy Black-Cockatoo habitat revegetation programs. Around 1 kg of Sugar Gum has been used in Glossy Black Cockatoo projects.
As well as providing a service to the community, the seed bank operates as part of the school's agriculture and environment program. Students take part in collecting and processing the seeds and do germination trials to assess viability. Using seed from the seed bank they learn to store seed, grow seedlings, keep records and design revegetation plans, and are involved in planting trees for specific projects. The children from Parndana Area School have been involved in Glossy Black-Cockatoo habitat regeneration at all stages from seed collection to tree planting, both within Lathami Conservation Park and on private land. These programs have also included children from Black Forest Primary School through the schools' Land-Link program.
The equipment at the seed bank, including secateurs, loppers, fire rakes, seed sieves and reference books, is available for community use. Facilities at the bank include storage areas, a drying shed, a barbecue (for cracking Banksia cones), a propagating shade house and a hotbed propagator. The watering system will be up-graded in the coming year. The school also provides administrative support and facilities.
The seed bank does not aim to operate at a profit and its operation is currently funding dependent. It aims to become self-funding over the next few years. It is run by a co-ordinator who is paid for 6 hours a week, 20 weeks of the year, but who puts in considerable volunteer over-time.

| 2.6 | Trees For Life |
Trees For Life provide many of the seedlings used to re-establish Glossy Black-Cockatoo habitat on Kangaroo Island. Trees For Life is a non-profit community group that was established in 1982 and now has 10,000 members across South Australia. As well as providing seeds, potting materials and seedlings for revegetation projects, Trees For Life runs 130 Bushcare projects on the mainland, in which volunteers help to rehabilitate threatened bushland. There are 88 members on the island; 57 are growing trees for planting back on the island.
Trees For Life grows about 1.5 million seedlings each year. In 1998, 33,000 of these seedlings will be planted on Kangaroo Island, including 4,300 Drooping Sheoaks and 2,775 Sugar Gums. Seed or seedlings are also available for 33 other Kangaroo Island native plants suitable for firewood, fodder, erosion control, shade, shelter, honey, revegetation or reclamation of saline ground. Materials provided to growers include up to 20 boxes of tubes, soil, and slow release fertilizers. Seed provided is collected by volunteer teams or purchased from commercial sources, including the Kangaroo Island Seed Bank. All seedlings designated for Kangaroo Island are grown from locally collected seed. Landholders or volunteer growers sometimes collect their own seed and simply use the potting materials provided.
Annual membership of Trees For Life is $25 and there is an order lodgement fee of $15. Members are entitled to order up to 500 seedlings, or materials for growing up to 1000 seedlings, all of which is provided free of charge. As planning for replanting must be done in advance, orders for seedlings or seed and growing materials are placed in autumn, a full year before the seedlings are to be planted out. Seed, potting materials and growing instructions are sent to the growers in November. Landholders are advised to contact their local PIRSA revegetation officer for assistance in deciding on the most suitable plants and planting methods to use, although a landholder's advice booklet is also available on request. The cost of materials and administration is covered through sponsorship (20 cents per plant). However, the bulk of the expenses is the contribution of volunteers and landholders who grow the seedlings (80 cents per plant).
Community involvement in Trees For Life has been growing at a phenomenal rate, with the number of seedlings grown doubling every two to three years. The Drooping Sheoak and Sugar Gum grown by Trees For Life has already contributed to re-establishing Glossy Black-Cockatoo habitat on Kangaroo Island, and will continue to do so in the years to come.

| 2.7 | Penneshaw Area School - Trees For Life |
The Glossy Black-Cockatoo has a high profile at Penneshaw Area School, and each year students do projects on the species in many subject areas. Since 1993, this has included growing seedlings through the Trees For Life program. Under the supervision of a volunteer co-ordinator, the children have propagated and planted thousands of plants.
The children collect seed locally and grow tube stock in pots and soil provided by Trees For Life in an open-sided shade house on the school grounds. Most seedlings go to landholders on the Dudley Peninsula who want to revegetate their properties with the native species, local demand determining which species are grown. Re-establishing Glossy Black-Cockatoo habitat is a high priority. Over the past 5 years around 2,000 Drooping Sheoak have been grown for this purpose.
Seed of Drooping Sheoak is collected in local feeding areas of the Glossy Black-Cockatoo. The seed is sown towards the end of the school year, and the tube stock is the ready for collection by landholders in April. The children often help plant the seedlings. This is done after the first rains. The seedlings are planted in the middle of a metre-wide circle from which the weeds have been pulled and top 2 cm of soil scraped away. No chemicals are used.
The work of the school is evident around the town, with stands of Drooping Sheoak doing well at the Bluff and above the Golf Course, and several of the projects funded by the Glossy Black Rescue Fund have benefited from plants grown by Penneshaw Area School.

| 2.8 | Friends of Deep Creek Conservation Park |
Deep Creek Conservation Park is on the southern slopes of the Fleurieu Peninsula, an area that once supported Glossy Black-Cockatoos. Several potential foraging and nesting areas have been identified within the park. However, these are separated from the closest mainland landfall to Kangaroo Island by cleared land, both outside the park and within the park in an area known as Blow Hole Creek. The revegetation of these areas should assist any Glossy Black-Cockatoos dispersing from Kangaroo Island to settle on the peninsula.
Friends of Deep Creek Conservation Park was started 10 years ago, and has an active core of 15 families from the southern Fleurieu Peninsula. Its first project was the revegetation of the northern part of Tapanappa Ridge with the indigenous Cup Gum Eucalyptus cosmophylla and a range of other local plants, including Drooping Sheoak. The group has also helped with track maintenance and established a half-hour walking track from the Glenburn headquarters that is suitable for wheel-chair access. In 1997, the group began a project to re-establish 15 ha of Glossy Black-Cockatoo habitat at Blow Hole Creek, inside the western boundary of the Deep Creek Conservation Park. This site was selected because of its potential to provide a conduit for Glossy Black-Cockatoos arriving from Kangaroo Island and moving to potential feeding areas within the park. Remnant Drooping Sheoak and steep sandstone slopes at this site indicate Drooping Sheoak probably dominated the original vegetation. About 5 ha of direct seeding was done in spring 1997 and a further 10 ha will be seeded in 1998. Before seeding, the area was sprayed with a 100:1 dilution of RoundUp®. Follow-up spraying is not planned. The site has been fenced with 9-strand electric wire powered by a solar panel. Once this area has been successfully revegetated, the group has set its sights on further revegetation projects within the park.

| 2.9 | Rotary Greening |
Rotary Greening was launched in August 1997, and is a collaborative venture between Rotary International (Districts 9500 and 9520) and Greening Australia [South Australia] Inc., both of whom are national, non-profit, community-based organizations. The aim of Rotary Greening is to coordinate and implement significant on-ground revegetation and habitat restoration projects and to develop associated educational resources within South Australia. The focus of this work will be on rehabilitation of the habitat of threatened species. Greening Australia, having been in the forefront of revegetation efforts nation-wide, brings with it considerable ecological, educational and technical expertise. Rotary, which also includes several environmental programs among its achievements, brings the commitment of a large active membership. The new venture is partially funded through Environment Australia.
| * | Providing voluntary labour to carry out both large and small scale projects, |
| * | Providing opportunities for students to participate in environmental projects that will enhance their environmental knowledge and skills, and |
| * | Generating sponsorship funds and assistance to support Rotary Greening projects and services. |
Over the next few years, Rotary Greening plans to undertake more than 20 revegetation projects. It will do this using about 220,000 seedlings propagated and planted by school and Rotary groups, involving 42,000 hours of volunteer labour. Glossy Black-Cockatoo habitat regeneration has been designated as one of the major projects to be undertaken. Other projects include the revegetation of Koala habitat on Kangaroo Island and Regent Parrot habitat in the Riverland.
Three Glossy Black-Cockatoo habitat restoration projects have been selected on the basis of original habitat type, suitability of the site for revegetation, long term management considerations, and likely use by Glossy Black-Cockatoos. Two projects on Kangaroo Island involve revegetation of cleared land around remnant patches of Drooping Sheoak that are fed on by breeding birds. One of these sites is within 6 km of an important group of nests. Access to Drooping Sheoak from these nests is so limited that the birds frequently fly twice this distance to find food. The other site is in the core area of the cockatoo's population, where the increase in bird numbers has been greatest. Both these sites have already been fenced with funding assistance from the Glossy Black Rescue Fund. Another site for revegetation has been selected on Fleurieu Peninsula, within the historical range of the cockatoos. This site will help form a link between the island and potential feeding areas in Deep Creek Conservation Park.
Rotary Greening projects follow the principle that only plants that are native to the site are planted, using seed collected from the local area, and ensuring all layers of vegetation are replaced. A total of 15,000 plants will be propagated and planted to revegetate Glossy Black-Cockatoo habitat. Tube stock will be used to allow community involvement at all stages in the projects. From early summer, seed will be planted directly into tubes and tended at the Greening Australia nursery at Flaxley. A soil mixture that includes slow release fertilizer will be used. Seedlings will be planted out in winter, depending on the onset of rains. Site preparation is likely to include ripping and spraying, depending on the condition of the site. Maintenance of the sites is to be negotiated with the landholders.
These projects are being organized after consultation with Department of Environment, Heritage and Aboriginal Affairs and the Glossy Black Rescue Fund, in order to provide maximum benefit to the recovery of Glossy Black-Cockatoos.

| 2.10 | University involvement |
Several university-based projects have contributed to the understanding of habitat requirements of Glossy Black-Cockatoo or the availability of suitable habitat. In 1996, John Pepper, University of Michigan, completed a PhD Thesis on the "Behavioural Ecology of the Glossy Black-Cockatoo Calyptorhynchus lathami halmaturinus". As well as providing detailed studies of cockatoo behaviour, John's work described the differential use of Drooping Sheoak across Kangaroo Island, and the characteristics of feeding trees and nesting sites. His research formed the basis of the first Glossy Black-Cockatoo Recovery Plan, which he wrote in 1994.
In 1994, Angela Paltridge completed an Honours Thesis at the University of Adelaide, entitled "The Feeding and Nesting Resources of the Glossy Black-Cockatoo Calyptorhynchus lathami halmaturinus on western Kangaroo Island, South Australia". Angela used the vegetation mapping that had been done by David Ball to identify vegetation types that were likely to support nests. This was followed up by on-ground estimation of hollow availability. This work has since been extended by the Glossy Black-Cockatoo Recovery Team, and was used as the basis of Mandy Andrew's work on the Southern Fleurieu.
In 1995, Mandy Andrews completed an Honours Thesis at the University of South Australia, entitled "Assessment of the Availability of Potential Nesting and Foraging Habitat for the Re-Introduction of the South Australian Glossy Black-Cockatoo, Southern Fleurieu Peninsula, South Australia". This project identified several extensive stands of Drooping Sheoak and suitable nesting areas on the Fleurieu Peninsula.
In 1995, Tamra Chapman, University of Adelaide began a PhD project on "Patterns of Seed Production in the Drooping Sheoak (Allocasuarina verticillata) and the Foraging Behaviour of the Glossy Black-Cockatoo (Calyptorhynchus lathami halmaturinus) on Kangaroo Island." The three focus areas of this project are
| (1) | Documentation of timing of flowering and seed development, |
| (2) | Description of cones and trees usage by the cockatoos, including tree selection, cone maturity, intake rates and seasonal variation, and |
| (3) | Examination of factors which may limit seed production, including pollination and the effects of honeybees, nutrients, and soil moisture. |
Sophie Bickford, University of Adelaide, is using a number of techniques including vegetation mapping, pollen analysis and GIS to reconstruct the native vegetation of Fleurieu Peninsula for her PhD thesis in geography. She hopes to use the remnant patches of vegetation to identify the former distribution of Drooping Sheoak and eucalypt forests. This work will contribute to mapping former Glossy Black-Cockatoo habitat and formulating management plans for the Fleurieu Peninsula.
| 2.11 | Kangaroo Island Bee-Keepers |
One aspect of habitat protection and rehabilitation is the protection of nest hollows from feral bees, which are present in most nesting areas. Feral bees were responsible for the death of at least one Glossy Black-Cockatoo chick in 1996, and may have caused the early fledging of a second bird. Within six months of the end of the 1996 nesting season, they had colonized six productive Glossy Black-Cockatoo nests. These hives were eliminated from the hives by placing Shelltox Pest Strips™ inside the hollows.
For the last three years Kangaroo Island Bee-Keepers have been trapping feral bees from Glossy Black-Cockatoo habitat across Kangaroo Island. Trapped bees are then used to augment commercial hives or to raise new queens of commercial stock. Ten commercial bee-keepers are involved in the program, and use 100 dedicated trap hives. These are placed close to nesting areas in the spring. Placement is changed as different crops, such as Canola, or native plants, such as Broom Bush Melaleuca uncinata, come into flower. It is the flowering of these plants, which produce copious pollen as well as nectar, which allows the hives to build-up and swarm. Placement of trap hives has been adjusted yearly to increase the number of hives that have been trapped. Hence, the number of swarms trapped increased from four in 1995 to ten in 1996, and 97 in 1997. The focus areas now include Dudley Peninsula, lower Cygnet River, MacGillivray, Island Beach and Cape Dutton. The program will run for at least 10 years, but is likely to be a permanent contribution of the Kangaroo Island Bee-Keepers to the conservation of Glossy Black-Cockatoos.

| 2.12 | Glossy Black-Cockatoo Recovery Team |
The Glossy Black-Cockatoo Recovery Team has the brief of over-seeing research and management to secure the future of the South Australian sub-species of Glossy Black-Cockatoo. Supported by state and federal funding, it brings together organizations involved in Glossy Black-Cockatoo conservation, as well as running a program of its own according to a recovery plan. The first recovery plan was written in 1994, and included both research and management actions. Its main concern was a low recruitment rate of juveniles to the breeding population. The research team of Stephen Garnett, Lynn Pedler and Gabriel Crowley has shown that predation at nests sites, principally by Brushtail Possums, is the main factor preventing recruitment, and is the most likely agent of decline on Kangaroo Island. However, with fragmentation of habitat and an increase in the area of crops on the island, competition for nest sites by other cockatoos is also a serious problem, a factor that may have been instrumental in the decline of the sub-species on the mainland (Crowley et al. 1998). Management of nesting sites to exclude possums and competing species has already reversed the decline on Kangaroo Island (Garnett et al. 1996; Prime et al. 1997). Other work by the team suggests availability of feeding habitat is more likely to be constricting the distribution of the cockatoos than to be limiting current population size (Crowley et al. 1998; Section 3). The team also reached the conclusion that, as long as habitat is available, an increase in the population on Kangaroo Island should lead to unassisted dispersal to the Fleurieu Peninsula, the only site for which there is incontrovertible evidence for the historical presence of Glossy Black-Cockatoos (Crowley et al. 1998).
As the focus of the recovery process shifts from research to management, so too has the composition of the recovery team. Bill Prime has been employed as the volunteer co-ordinator to maintain nesting sites and undertake the annual census, although Lynn Pedler will continue important population monitoring. Liaison with organizations working on the Fleurieu Peninsula has also increased, with the Threatened Species Network and Friends of Deep Creek Conservation Park assisting with the 1997 census. As the revegetation effort increases, it may be appropriate for groups contributing to habitat re-establishment to be represented on the recovery team.
