Dear Mr. Warneke,


Re. : APPLICATION FOR PERMIT TO EXPORT LEADBEATER'S POSSUM

TO FRANKFURT ZOOLOGICAL GARDEN


As we were told by Miss Pamela Conder recently, Mr. Des Hackett is intending to give up the breeding of Leadbeater's Possum and coniders disposing of some specimens to the Jersey Wildlife Preservation Trust and the Frankfurt Zoological Garden for future propagation.


We are most greatful to Mr. Hackett for the confidence he places in our work and would of corse like to take a small colony of this rare and endangered possum. It would be a great pleasure for us to maintain these mammals and to make breeding attempts.


Frankfurt Zoo has a new nocturnal house which opened two years ago. Up to now we have succeeded in reproducing 27 animal species there, among them also Sugar Gliders, Grey Cuscus and Australian Water Rats. Naturally, we cannot guarantee that we shall also succeed in propagating Ledbeater's Possum with good results. To my thinking the prerequesites are not bad in this building, however, which has been built with a considerable high technical expenditure so as to create the best possible husbandry conditions and fitting out of the animal enclosures.


The technical facilities give us the opportunity to provide practically any temperatures desired in each of the 44 cages, with day-nightvariations, which can be individually chosen by us. We are also in a position to regulate the air humidity through a sprinkler system as well as to adapt the illumination in the entire building according to the requirements of each of the enclosures. By using a dimmer every natural diurnal and nocturnal lighting can be imitated with all gradations. All the 44 cages - their front consists of thick glass and separate the animals from the visitors - are as far as possible fitted out as natural habitats and are adapted to the animals need. We always take great pains to establish animal displays ensuring that the inhabitants will feel at home and breed, and we have done our best particularly with regard to this new nocturnal house making use of all the modern thechnical means available.

An animal keeper especially experienced in the husbandry of small mammals and who had already cared for the old small mammal house is at our disposal as well as a group of a further six to seven keepers working under his supervision. Apart from a scientific assistantm also specialized in small mammals, there are a parasitologist and a contract verterinarian in our scientific staff who are responsible for the veterinary care of the animal stock.


Mr. Hackett's idea to give a second colony of Leadbeater's Possum to Jersey is very foresighted and i can only support it whole-heartedly. It would be most favourable to have two breeding groups in Europe so as to be able to help each other out by interchanging specimens, if need be. We are closely working together with the Jersey Wildlife Preservation Trust and there exists various breeding programmes between Jersey and Frankfurt.


In the case of your Department taking the decision to give Leadbeater's Possum abroad, we should be much obliged if you were to consider our application favourably and grant a permit to export some specimens to Frankfurt Zoo.


Yours faithfully,

Dr Dr Faust,


My apologies for the delay in responding to your letter of 2 April 1980, addressed to Mr R. Warneke, in which you apply for permission to obtain breeding stock of Leadbeater's Possum, Gymnobelideus leadbeateri.


I understand that Mr D. Hackett, who has been so successful in propagating this species, had indicated to you that he was anxious to relinquish his colony to some suitable scientific institution for research and/or display. You will appreciate that the species is of special zoological significance and of concern because of its uncertain status in the wild. G. leadbeateri is the sole representative of its genus and is endemic to the State of Victoria, where it has been declared the State Mammal Emblem. It is included in the National List of Endangered Species and in the IUCN Red Data Book.


This Division recognised the potential value in establishing a viable captive population and to that and encouraged Mr Hackett in his project to develop appropriate techniques of captive husbandry. Now that he has achived this aim and the colony has increased to a size that it must be transferred to more spacious facitities, the Division feels that it should be entrusted to the Melbourne Zoological Gardens where its husbandry can be developed further and refined in consultation with Mr Hackett.


However, it is anticipated that in time surplus stock will become available for transfer to other Australian Zoos able to provide the special facilities required, and eventually for export to zoos of such high international repute as the Frankfurt Zoological Garden.


On the matter of your request for Thylogal[a?] flindersi, I have fowarded your letter to the Tasmanian National Parks and Wildlife Service, the authotity responsible for the fauna of Flinders Island.


Yours faithfully,

Dear Mr. Cowling,


Re. : Leadbeater's Possum


Many thanks for your letter of 13 June 1980 pertaining to the above.


Needless to say I respect your decision and fully understand that your Division wants to keep these animals in their country of origin for the time being rather than exporting them to abroard. I very much hope the breeding will continue successfully which would be most important with respect to the uncertain status of this species in the wild.


Yours sincerely,


Dr. Richard Faust

Hackett captive breeding 5X.JPG In May of this year, I contacted an officer of the Department namely Mr. R. Warneke, regarding the number of leadbeater possums bred on my property. I explained during this phone call that I had reached the stage where any sought his advice regarding an approach made to me in January (17th), 1980 by two representatives from the Frankfurt Zoo who wished to discuss the availability of the leadbeater for introduction to their zoo. Their proposal was that we supply two pair - one pair for exhibition in their new nocturnal house, the other pair for housing in a special enclosure for research and breeding purposes. They also indicated that they advised a similar arrangement being made with Gerald Durrell on one of the Channel Islands (with whom they work very closely) for the purpose of ensuring there was success in their proposed programme for the breeding of a colony in Europe of these rare creatures.


The FWD officer indicated that it was a feasible proposition and suggested that a meeting be held at the Division's office at Heidelberg between he, his fellow officer Mr. Seebeck, a Monash University researcher - Mr. Andrew Smith - and myself. This meeting was held in early June of this year.


As arranged, we met at Heidelberg and Mr. Warneke produced a confirmatory letter, recived by F.W.D. from Dr. Faust, Director of Frankfurt Zoo in Germany, formally requesting permission of the Division for the export of these possums for the purposes outlined to me by his representatives. He indicated that he was aware of my willingness to co-operate in any way I could to ensure the survival of the species.


During discussion, Andrew Smith advanced the opinion that at least four colonies should be established within Australia of this possum, but in establishing the whereabouts of these colonies, the Division's officers agreed with Andrew and myself that Healesville would be totally unsuitable, but they indicated that in view of the tremendous contribution made to wildlife by David Fleay, O.B.E. it would be a fitting gesture, in recognition of his work throughout his life in the wildlife field, that his property at Burleigh, Qld should come high on the list. It was thought that Melbourne Zoo

should be contacted as it was more than likely they could be satisfactorily housed there in a similar manner to that contemplated at Frankfurt and it was agreed that Messrs. Warneke and Seebeck would contact Mr. Dunbavin Butcher regarding this.


Andrew and I agreed with the foregoing, although I raised the question as to whether the advanced age of David Fleay would be detrimental to the plan. It was considered that this would have no bearing on the feasibility of the project. The officers then suggested that I approach David Fleay by letter to gain his acceptance of the plan. They, in turn, would respond to Dr. Faust indicating that the matter would receive consideration. As the meeting broke up, I again asked of the officers if it was correct for me to proceed, approach David Fleay and make the necessary arrangements to which they responded in the affirmative, giving no indication of any impediment to the plan.


Attached to these notes is a copy of David Fleay's response, in which he expressed his acceptance of the plan, and as arranged at the meeting, I travelled to Burleigh to verify that the conditions at this site were suitable and that the possums would be housed in enclosures as specified by myself (20' long x 7' high x 9' wide) as being the desired size for the comfort, well being to ensure the breeding of these creatures. Mr. Fleay accepted these specifications and indicated that he would especially build such an enclosure commencing immediately to ensure the availability of adequate housing as soon as they arrived.


I also established that provision was being to ensure that this establishment would continue, regardless of Mr. Fleay's well being, by involvement of Qld. National Parks and wildlife Service.


On my return from Queensland, I again contacted Mr. Warneke to inform him of the results of my discussions with David Fleay. I requested him, on behalf of David, to put the necessary documentation into effect to enable the one pair of leadbeater possums to be transported to Queensland. David Fleay had indicated that he would await the Victorian Division's notification to approach the

Letter to FWD from Hackett 16/7/80 page 2/3 2


Image Transcript Margin Notes Body of Transcript

Queensland authority for the entry permit, etc. Mr. Warneke then indicated that I should make an appointment to see you without delay.


In view of the fact that Mr. Fleay is progressing with the structure and the urgent need for me to reduce the surplus numbers of possums on my property, I would request early attention to this documentation, particularly in view of the fact that this would be the ideal time to move the possums with approach of the breeding season in August.

Hackett captive breeding 8X.JPG Dear Mr Hackett

Thanks for this nice letter and combined generous gesture from you and the Victorian Fisheries & Wildlife Department regarding a pair of Leadbeater Possums. I’d be delighted to have them – a climax if you like to all the hard years of search which were so near and yet so far!

Also when you are up at the end of June it would be most helpful to receive the useful tips that you are obviously, in such an excellent position to impart.

On my part I’d like to present you, as soon as you wish, with a pair of sub adult Squirrel Gliders.

Perhaps it would be a good idea to have the Victorian F&W Dept. Listed as both the receivers of these and also senders of Leadbeaters couple.

This place is, after all , a B class Quarantine Station.

[?]ide Memoire of a meeting held on Friday 23rd January, 1981, in the Zoological Gardens to discuss the feasibility of the Zoological Board of Victoria assuming jurisdiction for a Leadbeater possum collection maintained by Mr. Des Hackett of Hawthorne, Victoria.


Presen:    Mr. A. Dunbavin Butcher - Chairman, Zoological Board
 
           Mr. S. Cowling - Fisheries & Wildlife Division

           Mr. R. Warneke - Fisheries & Wildlife Division

           Mr. D. Hackett

           Mr. G. Shotter - Melbourne Zoo


Purpose of Meeting: To discuss, in general terms, the practicalities of the request from Fisheries & Wildlife Division for the Board to assume responsibility for the Leadbeater possum collection maintained by Mr. Des Hackett.


Details of Collection: The colony comprises 7:17:2 held in seven compatible social groups, mainly comprising unmated single females, in an effort to reduce the rate of breeding.


Mr. Hackett wishes to retain 1:2 original animals, well beyond breeding age, and hand-over 6:15:2 animals. Of the 6 males, only 3 are potential breeding stock.


Housing: The animals are currently housed in free standing enclosures measuring approximately 9m. long x 2.5m. high x 3.8m. wide and D Hackett advises that the ideal breeding enclosures would be 6m. long x 2.2m. high x 2.8m. wide. Enclosures should ideally be separated by at least 2m. although a solid barrier between adjoining enclosures would suffice.


Activity: The animals spend most of their active period building their resting facilities and it is important that sufficient quantities of bark strips are always available for this purpose. The animals are very active and are spectacular leapers.


Social Behaviour: Paired animals mate for life with male offspring remaining with the parents indefinitely. The mother ejects female offspring some time between 1-4 years of age. The animals are very territorial and aggressive.


Climatic Adaptability: Although occuring naturally in an Alpine habitat there have been no problems observed in their adapting to the warmer Melbourne climate. These animals are on average 20-40 grams heavier than the average wild caught weight of 140-160 grams but this is more likely attributed to their captive high protein diet.


..../2

Letter from Zoological Board to FWD page 2/3 3/2/81


Image Transcript Margin Notes Body of Transcript
Hackett captive breeding 14X.JPG - 2 -


Diet: D. Hackett willing to provide complete details of his high protein diet. Supplementary natural feeding of beetles and other insects attracted into enclosure by electric light is believed to be an important dietary factor.


Method and Timing of Acquisition by Zoo Board: D. Hackett prepared if necessary to hold collection up to June 1981 with compatible groups being relocated gradually, either direct to Board property or to other Zoos as determined. Ideally, established breeding groups would be the first to be relocated. Fisheries and Wildlife Division would be prepared to consider providing several wild caught males to pair up with excess females if necessary. D. Hackett would be prepared to supervise the introduction of these wild caught males to the excess females prior to their relocation.


Relocation: D. Hackett indicated his interest in some animals being sent to the Frankfurt Zoo. It was noted that both the cost of accommodation and the allocation of sufficient space was of concern to the Board and would have to be considered further.

The Honourable W.V. Houghton, M.L.C.,

Minister for Conservation,

Ministry for Conservation,

240 Victoria Parade,

EAST MELBOURNE. 3002


Dear Mr. Minister,


A Mr. Des Hackett of Blackburn has held a colony of Leadbeater's possums under the authority of the Fisheries & Wildlife Division for more than a decade. He has demonstrated considerable skill and understanding in the maintenance and study of this colony.


The research in which he himself, and other autherized persons, has been involved has come to a conclusion and the question of the future of the colony is a matter of some urgency. The Fisheries & Wildlife Division has requested the Zoological Board to accept responsibility for the colony which should not be released in the wild. In addition it would take many years of patient work to re-establish a similar group of these animals.


As you will be aware the Leadbeater's possum is one of this State's faunal emblems and it is listed as an endangered species.


The fact that there are considerable problems in keeping the species in captivity raises many real difficulties. This arises from the fact that the number of individuals that can be held in a compatible social group is limited indeed.


The board is advised that the Fisheries & Wildlife Division would not oppose the transfer of some of the colony, or its future offspring, to other accredited zoos, nor indeed, overseas (the latter subject to the approval of the appropriate Commonwealth authorities).


...2/

There is an existing capacity to hold several pairs of these animals at the Sir Colin MacKenzie Fauna Park but, if the colony as a whole is to be adequately catered for, there remains a need to house part of it in the Royal Melbourne Zoological Gardens.


It is the view of the Board that as the species is this State's mammal emblem, it is highly desirable that at some time in the future a special display should be prepared. In the meantime, it will be necessary to provide holding accommodation at Healesville would not be adequate.


The Board's current financial position will not permit it to become involved in this exercise unless special financial provision is made. Fortunately, the type of holding accomodation needed is not complex.


A request is made for the urgent provision of the sum of $20,000 to permit the erection of the necessary cages. An early decision is necessary as Mr. Hackett is not in the position to hold the colony for more than a few months longer.


This colony is of particular value for a number of reasons and the basic purpose of the proposed exercise is to permit the provision of material for continuing programme of study in conjunction with the Fisheries & Wildlife Division.


Yours sincerely,


A. Dunbavin Butcher

Dear Mr. Wharton,


Following earlier correspondance in respect to your Division's request that the Board accept responsibility for the [disposal?] of the colony of Leadbeaters' possum helde by Mr. Des Hackett under your authority, you will be aware that special funds have now been made available to the Board to make this possible.


As a next step it would be appropriate that suitable accomodation be discussed in some detail and designed to suit a particular site within the Zoo reserved for this purpose.


We would suggest that an on site meeting between Mr. Cowling or his nominee, Mr. Hackett, Mr. Graham Shotter and one of our Curators be held in the near future in order that we may prepare a complete design proposal with cost estimates for consideration by the Board. It is desirable that the design and layout should carry the endorsement of both Des Hackett and our Division.


Perhaps for convenience, such a meeting could be convened by telephone say for the latter part of the first week of May.


Mr. Hackett has not yet been formally advised of the progress being made and perhaps this could be left until we have your comment on the proposal in this letter.


Yours sincerely,

Dear Des,


Following our on site discussions in the Zoo regarding the design and location of the proposed Leadbeater's possum breeding and holding enclosures, I am now enclosing a copy of our final proposal for your information and possible comment.


I would draw your attention to the change in siting of the complex from the original east west alignment as discussed on site to being on the other side of the pathway with a north south alignment. It is considered that by doing this existing trees can be far better utilised to shade the roofed nesting areas during the hotter periods and that the higher midday sunlight will not fall along the length of the enclosures.


We proposed to have a contractor prepare a price for construction for the complex in the next week or so and if you would like to better make any comments beforehand, could you give Ernie Weber a ring on 347 1522 and discuss the details with him direct.


Many thanks for your assistance.

Hackett captive breeding 20X.JPG MODULAR BREEDING CAGES FOR LEADBEATER'S POSSUM


CONSTRUCTION BRIEF -


Requirements are for the prefabrication and erection on site of seven (7), steel-frame cages for off-exhibit breeding with special reference to the following notes:


1 - Framing structure should be welded and painted prior to being covered wirh either fibro-cement sheeting (solid partitions) or weldmesh (roof and service lane areas) as specified on attached drawings. Solid diving partitions and side panels should also be covered by weldmesh to prevent escape if fibro-cement is broken.


2 - Roofed nesting area at rear of enclosures should be covered with corrugated fibro-cement, sloping to the rear and with a 100'mm overhang at the rear sides. Weldmesh covering on cages should continue under the roofing over the nesting area and the roofed area be slightly elevated to promote ventilation in hot weather. Flashing around roof edges should not be used.


3 - All gates are of welded steel frame with weldmesh fabric covering. Padbolt locking mechanisms are required both externally and internally on all gates.


4 - A smooth concrete pad should form the working surface for the service laneway while other ground surface areas will be soil or sand.


5 - Water supply should be provided to a point just outside the service entrance to the complex.


CONSTRUCTION MATERIALS
