• Locality case study.

What is Wildcare?

A group of people who care

• Established in 1992
• Operate a 24 hour/7 day emergency telephone service to

facilitate the prompt rescue of wildlife

• Train volunteers in all aspects of the rescue and

rehabilitation of wildlife

• Promote the protection of natural habitat
• Educate the general community in all aspects of wildlife

and their needs

• Operates predominantly Gympie south to Border & out

to Toowoomba.

Wildlife Rescue Fraser Coast

• Alliance of privately permitted rehabilitators and those

permitted under ANARRA.

• Operate a 24 hour/7 day emergency telephone service to

facilitate the prompt rescue of wildlife

• Promote the protection of natural habitat
• Educate the general community in all aspects of wildlife

and their needs

• Operates predominantly in Fraser Coast region.

Rehabilitation Volunteers

• Must hold a “Specialise Koala Rehabilitation Permit”
• Must complete regular training
• Generally care for wildlife in “home-based” facilities
• Work closely with our partners:

– Queensland Environment & Heritage Protection – Currumbin Wildlife Hospital – Australia Zoo Wildlife Hospital – RSPCA Queensland – Local veterinary surgeries

Aim - To rescue, rehabilitate and release back to the wild

Koala Rehabilitation Causes and Issues

Why do our koalas need us?

• Road trauma
• Domestic animal attacks
• Disease
• Entanglement
• Orphaned
• Tree falls
• Injury from habitat destruction/loss
• Injury from misadventures
• ….

All require rescue and immediate veterinary assessment and treatment.

Does it need to be rescued?

We need to be able to:

• understand koala ‘normal behaviour’ and body language;
• identify koala habitat and know where koalas live;
• identify a male from a female;
• identify independent young from dependent;
• identify common diseases;
• identify injured koalas;
• recognise pain in koalas;
• assess scats; and
• be able to ask for help when needed.

Rescue Call …Lots of questions asked

Essential that we obtain an accurate history of the animal to determine whether it is sick or injured and whether it needs to come into care.

• When was the koala first sighted?
• Has it been on the ground for a period of time? For how long?
• Does it appear sick? Eyes, bottom etc.
• Is it eating?
• Is it exhibiting unusual behaviour?
• Was any commotion heard from dogs.

Normal Behaviour

NORMAL NOT SO NORMAL Sitting in a tree Sitting on the ground Responsive to stimuli (noise, presence of rescuer) Non-responsive to stimuli Moving on the ground for short periods Moving on the ground for extended periods – sitting and staying inactive or bumping into things On the move through the day (particularly in breeding season and in cooler weather) On the move through the day (particularly in very hot weather) Resting in non-food trees Reported in non-food tree for more than 24 hours Attempting to climb security screen doors

• Generally koalas are gentle and placid animals UNTIL they feel threatened (i.e.

being handled).

• Become disorientated easily – particularly when people are standing around the

animal and trying to coax it in a particular direction

Assessment

Demeanour – Healthy

• Bright, alert and responsive to

disturbance

• Ears should become erect when

disturbed

Assessment

Demeanour – Unhealthy

• Unresponsive
• Able to approach closely

Assessment

Position – Healthy

• Healthy koalas should be up a

tree during the day.

• If on the ground, they should

move away when approached.

Assessment

Position – Unhealthy

• Sleeping on the ground
• Sitting at the base of a tree for a

period of time

• Does not move away when

approached

Gait/Mobility – Unhealthy

• Limping
• Falling to one side
• Circling

Assessment

Body Condition - Healthy

• should be well nourished and

slightly pot-bellied

• pelvic bones and spine should

not be discernible

• 9 or 10 = excellent

Assessment

Coat – Healthy

• Should be dense, grey and

uniform

Assessment

Coat – Healthy

• Females with large back young

may have brown, patchy fur where the joey has been gripping on

Assessment

Coat – Unhealthy

in appearance

• Hair loss
• Scaly, encrusted skin
• Any signs of wet fur which might

indicate saliva from a dog

the eyes

Assessment

Eyes – Unhealthy

• Crust formed over eyes
• Inflammation around the eye

Assessment

Vent and Rump – Healthy

• Bottom should be clean, white,

dry and free of dirt or dark brown stains

Assessment

Vent and Rump – Unhealthy

• Dark stained bottom (brown

colour)

Injuries/Conditions

Road Trauma

• Fractures
• Head trauma /

neurological damage

• Internal bleeding
• Paralysis
• Orphaned young

Injuries/Conditions

Dog Attack

• Fractures
• Lacerations
• Bruising
• Internal

bleeding

• Infection

Any koala with evidence of saliva MUST receive IMMEDIATE VETERINARY ATTENTION!!

No exceptions.

Injuries/Conditions

Chlamydia Several forms:-

• Conjunctivitis
• Uro-genital
• Reproductive

Chlamydia – Conjunctivitis Form

Photo: AZWH

Chlamydia – Cystitis

Diagnosed by:-

• Clearview Test
• Gross observation

Treated with:-

• Chloramphenicol injections for 45

days

Note protrusion of penis in male koala. This is often a sign

• f trauma to the

lower body region (ie pelvic injury)

Chlamydia – Cystitis

Gross necropsy of koala with advanced cystitis. Note the thickened bladder wall and haemorraging.

Immunosuppression / Koala Retrovirus (KoRV)Aids

• Poor condition
• Lethargic
• Ulcers in and around

mouth

• Dermatitis
• Pot belly

Cancers/Retrovirus

• Osteochondrona (Slow

growing cancer of mixed cartilage and bone)

• Leukaemia
• Lymphoma

Orphan Care

• Raising orphaned koala joeys is an intensive job
• Lots of veterinary intervention required
• Lots of leaf cutting, washing, cleaning ….

Koala crossing road

• Human safety above all –

ensure people stay off the road

• If safe, slow traffic and allow

koala to move in the direction that it wants to

• Stay well clear of the koala –

they become disorientated easily

Common Concerns

Mother trying to save baby

• Reported as ‘baby’ on outer limb

hanging for dear life and larger koala trying to ‘save it’

• 99% - male trying to ‘court’ a

female!

• Generally unable to rescue

female as risk of her falling is great

• If one falls, cover with a blanket
• r laundry basket and call for

help

Koala knocking on door

• Ensure all dogs secured and out
• f sight
• Turn all lights off
• Leave the koala to move on of

its own accord

• Should have moved on within an

hour – if not, should be assessed by experienced koala rescuer to ensure okay.

Lost koala

• Reported in area ‘where

koalas shouldn’t live’

• If appears healthy, leave to

move on of its own accord

• Contact experienced koala

rescuer who knows the local area for advice

Misadventure

• Entanglement
• Entrapment
• Swimming Pools

Dispersing Young

• Koalas become independent at 12-18

months

• Juveniles will then disperse from mother’s

home range

• Sexually mature at around 2 years of age
• Will often still be close to mum so

important that they are not ‘kidnapped’ from their mother

• Many reports of ‘orphaned’ koalas are

actually dispersing young

• As a rule – smaller than a football should

be considered too young to be away from mum

Back Young

11-12 inches in height (sitting)

Adult / Mature

Basic Koala Rescue Techniques

• Koalas must be handled gently and

confidently

• They are extremely strong and have

the ability to inflict serious injury

• The flagging technique carries a degree
• f risk to the koala
• Much easier to rescue if on the ground

– do not encourage to go up a tree

• Do not rescue if not necessary as

koalas suffer from stress easily

Basic Koala Equipment

• Large top opening wire

cage

• Blankets and towels
• Cage cover
• Heat source (hot water

bottle, instant heat packs)

• Flagging poles
• Plastic bags and bright-

coloured cloths for end of flagging poles

• Koala trap
• Binoculars

Flagging

• Concept is based on the pretense that if a koala perceives that

the threat above it is greater than the one below it, then it will retreat down the tree.

• Aim - To get them down within reach quickly so that they don’t

have time to think about what is happening!

• If risk of fall to koala is high, we use alternative methods

Trapping

Use of a humane trap made from aluminum and Perspex with a corflute ‘fence’ constructed around tree.

Koala Admission Records

• Sourced all admissions through Australia Zoo Wildlife

Hospital from 2004-2016 (Full EHP records not forthcoming). Closest official Koala Treatment Facility to BMRG area

• Biased – By virtue of wildlife hospital - only include Koalas

where humans have intervened or acted

• Full longitudinal tracking needed for the ‘full’ story in the

wild

• Data issues – change in database during timeframe and

not 100% accurate suburb name entries

662 Koala’s admitted to AZWH (some multiple visits) between 2004-2016 from BMRG region. Number extremely conservative of BMRG Region rescues:

• Likely many more ‘admitted’

elsewhere for more urgent care – eg

• bvious euthanasia’s or more local

care.

• Many DOA cases would be

unreported.

• Issue with Chloraphenicol access in

2014 for 9 months – many Koalas never caught or sent.

How to Help Koalas

• Protect and retain existing koala habitat
• Plant koala food trees – helps all wildlife
• Restrain dogs – particularly at night
• Always report dog attacks
• Provide exit routes from pools
• Report diseased koalas early

Until help arrives…

Sick and injured koalas:-

• Human safety above all else
• Keep the koala on the ground with a

laundry basket or by placing hand on top of head from behind – do not encourage up a tree!

• Keep dogs away out of sight
• Do not pick up – wait for an

experienced koala rescuer to arrive
