platydemus manokwari , also known as the new guinea flatworm , is a large predatory land flatworm that has become an invasive species in many countries .

native to new guinea , it was accidentally introduced to the soil of many countries .

it was also deliberately introduced into two pacific islands in an attempt to control an invasion of the giant east african snail .

it eats a variety of invertebrates including land snails , and has had a significant negative impact on the rare endemic land snail fauna of some pacific islands .

it has become established in a wide variety of habitats .

it was recorded in 2014 from a hothouse in caen , france , its first finding in europe , and in 2015 from new caledonia , wallis and futuna islands , singapore , solomon islands , puerto rico ( first record in the caribbean ) , and florida , usa .

the researchers said that " while most of the infected territories reported until now were islands , the newly reported presence of the species in mainland us in florida should be considered a potential major threat to the whole us and even the americas " .

depending upon the outcome of an environmental risk assessment and related investigations , threats from platydemus manokwari may need to be responded to in a similar manner to the invasive new zealand flatworm arthurdendyus triangulatus . this species is now subject to an eppo standard regarding import requirements ( eppo , 2000a ) and nursery inspection , exclusion and treatment ( eppo , 2000b ) for the flatworm ( murchie , 2010 ) . the problem with p . manokwari is that even though it is primarily an environmental threat , it does not “indirectly affect plants through the effects on other organisms” . consequently there is the possibility that responsibility for managing this invasive species may fall between the remits of agricultural and environmental regulatory bodies . this could delay effective management of p . manokwari .

with it . genetic testing reveals that there are two different geographic lineages but areas where the beetle is invasive , they have hybridized . the two lineages may be considered as two separate species .
state fish and wildlife departments monitor the potential introduction of invasive plants and animals from outside their jurisdictions . alligatorweed , for example , is an invasive aquatic plant that originated in south america and can not only endanger native species , but also put humans at risk by reducing water quality .
the serious negative environmental impacts of platydemus manokwari on the biodiversity of native land snails in the indo - pacific are well documented . the risks posed by the incursion of this species in france have not yet been assessed . the european union has recently proposed new legislation to prevent and manage the rapidly growing threat to biodiversity from invasive species ( european commission , 2013 ) . the proposal centres on a list of invasive alien species of concern for europe , which will be drawn up with the member states using risk assessments and scientific evidence . whether or not platydemus manokwari will be included on this list remains to be seen .

waterhouse & norris ( 1987 ) considered that p . manokwari appeared to be an opportunistic carnivore and generally unselective in the choice of prey . success of platydemus manokwari as a biological control agent for achatina fulica can be attributed to its polyphagy , resistance to starvation , ability to survive and reproduce on alternative prey and potential to reproduce rapidly in synchrony with prey populations ( winsor , johns & barker , 2004 ) .

as yet there are no known specific biological control methods for platydemus manokwari . terrestrial flatworms are considered to be top - level predators in the soil ecosystem ( sluys , 1999 ) . although nothing appears to be known about natural enemies of platydemus manokwari , examples of predation on other species of land planarians by soil and associated fauna are known , mostly under laboratory conditions . they include an instance of predation of the neotropical species obama trigueira ( e . m . froehlich , 1955 ) by enterosyringia pseudorhynchodemus ( riester , 1938 ) ( froehlich , 1956 ) , and predation of five species of land planarians by p . manokwari ( ohbayashi et al . , 2005 ) . a chance field observation led to laboratory findings that arthurdendyus triangulatus was eaten by larvae and adults of species of a carabid and a staphylinid beetles ( gibson , cosens & buchanan , 1997 ) .

extremes in the density of dorsal pigmentation may cause p . manokwari to be confused with platydemus bivittatus recorded from milne bay , new guinea , and platydemus quadristriatus from the tonga islands . specimens with heavily pigmented dorsal stripes , as may occur in old individuals , could approach the external appearance of p . bivittatus , but would lack the fine dark median pre - ocular stripe present in the latter species . also the distance between the mouth and gonopore in p . bivittatus is considerably less than in a similar sized specimen of p . manokwari . the two species can be readily distinguished on the basis of their internal anatomy . similarly , specimens of p . manokwari in which only the margins of the brown dorsal stripes are evident on a lighter ground colour ( as in a specimen from lockhart river , queensland , australia ) approach p . quadristriatus , although may be distinguished from this species by a pale dorsal median stripe present in p . manokwari .

predation by platydemus manokwari on acusta despecta sieboldiana and bradybaena similaris eggs did not occur during the experiment . some p . manokwari individuals were observed crawling on the eggs , but they did not seem to recognize them as food . however , once snails hatched , p . manokwari individuals of various sizes ( 5–270 mg ) preyed on hatchlings of a . d . sieboldiana , although the smallest p . manokwari specimen ( 2 mg ) did not . predation behaviours were not observed , but one p . manokwari individual was found holding a cleared snail shell , covering it with its ventral body near the pharynx . platydemus manokwari should be able to move small snails to its pharynx using its muscular body ; thus , no ‘gape limit’ for predation on land snail hatchlings should exist . although insufficient number of b . similaris hatchlings prevented us from conducting predation experiments on hatchlings of this species , hatchlings of b . similaris were also predated right after hatching , indicating that our result should be robust for multiple species of snails .
the 2 - mg p . manokwari specimen did not feed on hatchlings of a . d . sieboldiana . this individual may have been too small to attack a snail by itself . as gregarious attacks by p . manokwari allow them to prey on larger land snails ( sugiura , 2010 ) , small p . manokwari individuals may only be able to feed on land snails when joining larger p . manokwari in attacking snails . kaneda et al . ( 1990 ) reported that the size of p . manokwari hatchlings ranged from 0 . 8 to 26 . 4 mg ( mean ± sd , 11 . 77 ± 6 . 56 ) , and extremely small hatchlings usually died within a few days . in our experiment , the smallest p . manokwari individual that preyed on snail hatchlings was 5 mg , which suggests that almost all active p . manokwari , regardless of size , could prey on snails as small as 2 mm .

platydemus manokwari has been used as a biological control agent for the giant african snail . alien soil animals can be unintentionally introduced by commercial trade among islands and continental landmasses ( sugiura 2008 ) . globalisation of commercial trade may have helped the transfer to non - invaded areas ( sugiura 2009 ) . movement of ornamental plants , potted plants , and other materials with soil can transfer p . manokwari to new areas ( sugiura 2009 ) . quarantine procedures for potted plants and other soil containing materials that can carry invasive flatworms are needed to protect against invasions in warming temperate areas ( sugiura 2008 , in sugiura 2009 ) . platydemus manokwari can readily be transported by soil on construction machines ( okochi et al . 2004 ) .

platydemus manokwari has a most unpleasant astringent taste ( l winsor , pers . obs . , 1994 ) , just as has been noted for other species ( dendy , 1891 ) . bellwood ( d bellwood , pers . comm . to lw , 1997 ) in his private urban garden , remarked that free - range domestic bantams that noticed p . manokwari on an upturned log pecked at , took the flatworms into their mouths , then immediately rejected them ; when at a much later time p . manokwari was subsequently noticed by the bantams they refused to peck at the flatworms . this is similar to behaviour of domestic fowls offered caenoplana spenceri ( dendy , 1891 ) . predation of flatworms by native species of birds has not been reported .

did you know that there is an interactive database of invasive species eradications on islands ? the database of island invasive species eradications has compiled information worldwide for islands that have eradication programs for invasive species . you can click on any of the marked islands and a details box will popup and show what the target species are , what stage the program is in ( in progress , successful , or failed ) , and the last date of progress update . many of the islands off of the u . s . coast have eradicated ungulates ( sheep , goats , deer , etc . ) , rabbits , dogs , cats , and rodents . you can also search by a few different filters if you are interested in a certain species , place , or eradication status or method .
an undesirable consequence of globalization , a relatively modern phenomenon , has been an increase in the number of biological invasions that challenge the conservation of biodiversity and natural resources ( secretariat of nobanis , 2012 ; simberloff , 2014 ) . invasive alien species ( ias ) have been defined as “plants , animals , pathogens and other organisms that are non - native to an ecosystem , and which may cause economic or environmental harm or adversely affect human health . in particular , they impact adversely upon biodiversity , including decline or elimination of native species–through competition , predation , or transmission of pathogens–and the disruption of local ecosystems and ecosystem functions” ( convention on biological diversity , 2009 ) .
a number of species of terrestrial flatworms will , when moisture conditions are right , seek prey above the ground . platydemus manokwari has been observed feeding on both juvenile and adult partulid snails at heights above one metre in trees , and in captivity the flatworm fed on specimens of partula sp . and pythia sp . ( eldredge & smith , 1995 ; hopper & smith , 1992 ) . experimentally , p . manokwari has been shown to track artificially created snail scent trails on the ground ( iwai , sugiura & chiba , 2010 ) , and up trees , supporting the hypothesis that the introduction of p . manokwari is an important cause in the rapid decline or extinction of native arboreal snails as well as ground - dwelling snails on pacific islands ( sugiura & yamaura , 2008 ) .

to find final - stage eggs , p . manokwari might have to cross over an egg by chance , because no trail would exist for the flatworm to follow . platydemus manokwari and land snails are often found beneath stones or logs , sharing microhabitats that are close to each other ( winsor et al . , 2004 ) , and encounters between p . manokwari and land snail eggs should occur frequently . as eggs cannot escape , predation by p . manokwari on final - stage eggs should have a strong influence on snail mortality rates . moreover , invasive flatworms have been found in many pacific islands , where minute genera , whose shells are less than 10 mm , constitute 60 % of the snail fauna ( vagvolgyi , 1976 ) . for effective conservation of land snails , we need to recognize that flatworms can act as significant predators on them , including small - bodied snails and hatchlings , leaving only early - stage eggs free from predation .

p . manokwari invasion can affect human health , because p . manokwari is a paratenic host of the nematode angiostrongylus cantonensis which causes ‘angiostrongyliasis’ ( asato et al . , 2004 ) . fresh vegetables contaminated with infected p . manokwari can be a source of human infection ( asato et al . , 2004 ) .
terrestrial flatworms ( land planarians ; terricola ) are predators of various soil invertebrates , such as earthworms , land snails , slugs , and arthropods ( ogren 1995 , winsor et al . 2004 , in sugiura 2009 ) . it was revealed that in the chichijima island , japan , p . manokwari fed not only on live land snails including predatory species , but also on other food resources such as live flatworms or a land nemertean species and the carcasses of slugs and earthworms ( ohbayashi et al . 2005 ) . while p . manokwari feeds on slow - moving soil animals such as earthworms , it prefers live snails over other organisms ( sugiura 2010 ) .

as humans have spread across the islands of the world we have taken with us , either purposefully or inadvertently , a remarkable array of plant and animal species ( see box 11 . 2 ) . these anthropogenic introductions are variously called exotic , alien or non - native species . some species persist simply as domesticated ( animal ) or cultivated ( plant ) species , while others become naturalized , i . e . they form self - sustaining populations within modified habitats ( henderson et al . 2006 ) . of these , some become feral or invasive , expanding into intact or semi - intact habitats . of this subset , a few species cause serious ecological impacts . these species are termed ecosystem transformers ( henderson et al . 2006 ) . based on a review of numerous case studies , williamson ( 1996 ) has suggested that only about 10 % of introduced species become established , with in turn about 10 % of these species achieving pest status .
) . additionally , intense herbivory by introduced mammals such as goats has caused the extinction of or decline in native plant species on islands ( e . g . , campbell and donlan
three of the chargers are in the hourly section , and six are in an area used for long - term parking .
the introduction of the snail - eating flatworm platydemus manokwari ( tricladida : rhynchodemidae ) has been considered a cause of the extinction of native land snails on several pacific islands . although p . manokwari is known to attack land snails on the ground , whether p . manokwari attacks snails on trees remains unclear . to clarify the effect of p . manokwari on arboreal snails , we examined survival rates of land snails experimentally placed on tree trunks ( 0 . 5–2 . 0 m above the ground ) in a forest on chichijima , ogasawara ( bonin ) islands , in the northwestern pacific ocean . the survival of snails experimentally placed on tree trunks with artificially created snail scent trails rapidly decreased for 7 days , and the mortality was caused by p . manokwari predation . however , snails placed on tree trunks without snail scent trails were not attacked by p . manokwari . therefore , p . manokwari climbed tree trunks , likely tracking the snail scent . we found that over 40 % of the snails placed on tree trunks with snail scent trails were eaten by p . manokwari within 7 days . this experiment supports the hypothesis that p . manokwari predation is an important cause of the rapid decline or extinction of native arboreal snails on pacific islands .
some species of terrestrial planarians ( flatworms ) are among the predators of land snails , but their predatory impacts have not been sufficiently studied . flatworms are known to follow snail trails to find prey and enter shells to consume snails ; however , eggs ( which do not have trails to follow ) and snails whose shells are too small for flatworms to enter may not be eaten . to determine whether an invasive flatworm , platydemus manokwari , preys on snail eggs or small land snails , we conducted a laboratory experiment in which we fed five eggs or five hatchlings ( 2 mm in diameter ) of a common land snail species found in japan to p . manokwari individuals of various sizes . egg predation did not occur within 10 days , but hatchling predation commenced on the first night ; only 9 % of the hatchlings remained on day 10 . platydemus manokwari did not recognize early - stage eggs as food , but started preying on eggs just before they hatched . flatworms can therefore be a significant predator on land snails , preying on even tiny land snails , leaving only early - stage eggs free from predation .
until now , platydemus manokwari was confined to the indo - pacific region within the bounds of the ogasawara islands , japan in the north ; near mackay in queensland , australia to the south ; french polynesia to the east ; with the most westerly extent of the flatworm in the maldives . the caen record of this species is a significant westerly extension of the occurrence of p . manokwari from the indo - pacific region to europe .

historic biological invasions include the passive dispersal of terrestrial flatworms , also known as land planarians . the main driver for this was probably horticulturalists of the 19th century using the then recently invented wardian cases to safely transport back to the hothouses and gardens of europe rare plants , together with soil containing cryptic exotic animal species ( winsor , johns & barker , 2004 ) . as a consequence , over 30 species of land planarians have established themselves as non - indigenous species in various countries outside their native range ( winsor , johns & barker , 2004 ) .

the mountain brushtail possum , or southern bobuck ( trichosurus cunninghami ) , is a nocturnal , semi-arboreal marsupial of the family phalangeridae native to southeastern australia .

it was not described as a separate species until 2002 .

mountain brushtail possum

the results indicated that the northern mountain brushtail possum from new south wales and queensland was indeed a different species from the southern mountain brushtail possum found in victoria .
the type specimens of the mountain brushtail possum now reside in the australian museum mammal collection .
mountain brushtail possum predators have not been well - reported . they are preyed on by non - native foxes (
measurements such as this one of the head length on this sedated mountain brushtail possum have been used to differentiate two distinct species – the short - eared possum that ranges from central nsw to central queensland , and the mountain brushtail possum that is distributed south from sydney to central victoria .

mountain brushtail possums are a little larger than the common brushtail possum , weighing between 2 . 5kg to 4 . 5kg . they also have some other features that distinguish them from the common brushtail possum . their ears are slightly smaller and more rounded , and are usually darker in colour .
the mountain brushtail possum ' s diet consists mainly of plant food such as leaves , fruits , berries , flowers , bark , fungi and lichens .
large decaying logs provide important runways for animals like the mountain brushtail possum – and assist them move through the dense ground cover that characterizes tall wet eucalypt forests .

mountain brushtail possums may influence vegetation community structure through their herbivory . allergic reactions to ectoparasites on the skin may be one of the main causes of the disease ' rumpwear ' in mountain brushtail possums ( hufschmid , handasyde , and beveridge , 2010 ) .
as a result , the existing species , trichosurus caninus , was renamed the short - eared possum , and the southern population was identified as a new species . the new southern species , trichosurus cunninghamii , retains the common name mountain brushtail possum .
montane ash forests where the mountain brushtail possum occurs are also used extensively for timber and paper production . current clearfelling methods are known to have significant negative impacts on populations of the species .

the mountain brushtail possum occurs in the wet sclerophyll and sub - tropical forests from victoria to central queensland , and for many years has been the subject of detailed ecological studies by dr lindenmayer . the studies showed distinct differences in external body measurements between northern and southern populations of mountain brushtail possum , which led the team to investigate further by extracting dna from blood samples in order to examine genetic differences between the populations .
) , which is found directly to the north of mountain brushtail possums . no sexual dimorphism is apparent ( lindenmayer , dubach , and viggers , 2002 ) .
however , dr david lindemayer , a regular associate of the australian museum , and colleagues from the australian national university recently discovered that the well known mountain brushtail possum , trichosurus caninus , was in fact not one species , but two .

it is rare these days for a new species of possum to be discovered in australia . the last recorded discovery was of the daintree river ringtail possum , pseudochirulus cinereus , in 1945 .
large wire cage traps baited with apple are used to catch the mountain brushtail possum . green apples are used as the preferred bait – probably because the ethylene used to ripen “granny smith” apples is attractive to animals while they are foraging ( perhaps because is resembles the smell of truffles which animals consume in several seasons of the year ) .
wires rescue hotline received a call from a local club to rescue a possum stuck in an industrial bin used for food scraps . the possum was stuck in the bin and due to depth of the bin unable to get back out .
mountain brushtail possums are found within the tall forest of the great dividing range and along the coast from south - east queensland to new south wales and victoria . they are patchily distributed and prefer to inhabit dense subtropical rainforests , wet sclerophyll and also tall eucalypt forests .
mountain brushtail possums are medium - sized ( 2 . 6 to 4 . 2 kg ) marsupials . they have thick , light gray - brown fur , and long , dark gray , bushy tails . they differ morphologically from their close relatives , short - eared possums (
in the event a possum is accidentally trapped during the process either reopen the closed entry point or remove a tile or raise a sheet of iron on your roof to allow exit . if this fails contact a local licensed reputable possum handler for immediate assistance .
image below shows mum possum shortly after rescue in bens rescue basket on route to leoni , clearly stressed and frightened by her ordeal .
most mountain brushtail possum females give birth to one baby a year . the offspring spend approximately 6 months in the pouch , then 1 to 2 months riding on the mother’s back . males spend the least amount of time with their female partners when the females are carrying young on their back , and are therefore much less involved in the care of offspring . juveniles remain with their mothers until they are approximately 18 months old .
possums communicate with each other in different ways , including using smells , sounds and visuals . some sounds they use are hisses , clicks , guttural coughs and screeching . the noises of the common brushtail possum are very similar to that of the mountain brushtail . they also have a variety of scent glands that provide each other with information such as identity , sex , and whether they are in season . they have around 11 scent - producing glands which are found on their sternum and cloaca , in their mouth and pouch , under their chin , on their ears and in between their digits .
this project is a long - term field - based study of the mountain brushtail possum and aims to provide new insights into the ecology , population dynamics and life history of this long - lived marsupial . the proposed work will have significant implications for the conservation of the mountain brushtail possum , particularly for predicting its response to logging - induced habitat changes and estimating the species prospects for long - term persistence in australian forests designated for paper and wood production . for example , the results of the investigation will help mapping and planning refugial conservation areas for wildlife conservation within wood production forests . this will , in turn , assist the improved integration of wildlife conservation and wood production in multi - use landscapes . the project is based around a trap - recapture study that has been running since 1991 at a 35 ha site at cambarville in the montane ash forests of the central highlands of victoria .
they tend to stay with their mother for much longer than other possum species . lifespan can be as long as 17 years , possibly longer . mountain brushtails live in hollow logs mainly found in old trees , so please think before cutting down that old tree , someone may call it home .
both male and female mountain brushtail possums appear to be long - lived , reaching at least 12 years of age . however , it appears as though fewer males reach that age than females ( martin and handasyde , 2007 ) . they are perhaps the longest lived marsupial ( viggers and lindenmayer , 2002 ) .

the southern animals of this species have olive grey fur . here on the north coast , the mountain brushtail can have a variety of colors , from the common grey colour to golden , black , brown and a combination of all . sexual maturity is reached at about 3 years of age . the female gives birth to normally only one young . pouch life is approximately 120 days , after which the juvenile possum will travel part time on mums back . mortality rate at this stage can be high .
the possum box you placed in your tree as option a may become the new home for your excluded visitor and provides a
win win
solution for all .
both male and female adult mountain brushtail possums have a mean home range size of 6 . 0 hectares , plus or minus 0 . 4 hectares . the home ranges of subadults are significantly smaller . however , this data was gathered in a forest setting . therefore , the home ranges of those populations living in scrub settings is unstudied and unknown ( martin , 2006 ) .
so what can you do to try deterring a resident possum from your home ? mountain brush - tail possums are often responsible for sleepless nights for suburban home occupants during entry , exit and general movements associated with roof and wall cavities . placement of a possum box in a tree around your property is advised as your first option . these are available from produce stores , specialist artificial home constructors or you can make your own ( see this site ) . the exclusion of possums from your home is quite simple requiring a small effort on your own behalf .
mum possum was taken back to the club the following evening and released back in to a large fig tree , joey delighting leoni but sticking her head out of the pouch as mum as released .
both were taken in to care by leoni . mum possum was given re hydration fluid and some native food and it did not take long before she was fast asleep with much movement within her pouch .
mountain brushtail possums are nocturnal , staying in dens during the day and leaving at night to forage . they are sedentary , often remaining in the same small home range for their entire lives . adults form strong pair - bonds and often share the same suite of different dens with their offspring . the home ranges of paired individuals overlap as well , as opposed to non - paired individuals , who remain more exclusive in their home ranges .
mountain brushtail possums breed once yearly , in january and february . offspring remain in the pouch for approximately 6 months and then ride on their mother’s back for another 1 to 2 months . offspring are usually weaned around september . juveniles remain close to their mothers until they are approximately 18 months old . females become sexually mature between 2 and 5 years of age ; males between 2 and 3 years ( martin , handasyde , taylor , and coulson , 2007 ) .
mountain brush - tail possums have proven highly adaptable to urban environments using trees , wildlife corridors , natural gullies , roofs and wall cavities often moving via telegraph poles , cabling and fences for traveling and foraging within close proximity to favored moist forest habitat .
it is a frightening thought as to how many animals may in fact go to the tip or even worse go in to the compactors when the bins are emptied , the operator of the compacter not aware that a live animal such as mum possum is trapped .
possums should not be relocated more than 25 meters from the point of capture after proofing has been conducted . be sure to ask contractors what methods they employ and choose the one which provides a solution for yourself and the best welfare outcome for the possum / s being trapped .
trapping and further management of mountain brush - tail possums should be done in accordance with requirements stipulated by the environmental protection agency and permits are issued to operators after examination as to the knowledge and suitability of the permit holder to actively manage suburban possums . often these permit holders are able to provide proofing measures to exclude further entry .
wires carer ben went on the rescue and had to hop in to the bin himself in order to reach the possum . she was fairly easy to catch due to being extremely stressed and worn out from having most likely spent considerable time trying to get out , it was also discovered that she was in fact a female with a large joey in the pouch .
place the paper back into the space and wait for the resident possum to make his early evening exit . inspect the locality every 10 - 15 minutes to determine when this has occurred and simply block the point of entry with a hard fixture like sheet iron . tightly compressed chicken wire reinforced with expandable building foam available in a can is ideal for hard to reach spaces . in some cases the replacement of a single tile or re - fixing of an iron sheet will solve the problem .

thank you for taking the time to provide feedback on the iucn red list of threatened species website , we are grateful for your input .
justification : listed as least concern in view of its wide distribution , presumed large population , occurrence in a number of protected areas , lack of major threats , and because it is not currently in decline .
this species occurs from ulladulla in southern new south wales , south to wombat forest and mount cole in central victoria . it occurs from sea level up to 1 , 300 m asl ( but usually above 300 m ; martin 2008 ) .
it is a mostly scansorial species , of various tall open and closed forest types . it can occur in exotic pine plantations and is a pest in regenerating pine plantations . the female gives birth to a single young after a gestation period of between 15 and 17 days ; the young have a pouch life of five to six months ( martin 2008 ) . along the snowy river it dens in rocky crevices instead of tree holes or logs .
there are no major threats to this species . clearance of land for agriculture and forestry is a threat in some parts of its range . foxes also can be a problem .
to make use of this information , please check the < terms of use > .
tail often used to grasp branches but cannot support its own body - weight .
males generally larger & heavier than females & may have reddish fur across shoulders .
males use scent glands under the chin , on the chest & near the anus to mark territory yet lack the characteristic staining of the chest like the common brush - tail as the fluid excreted is clear .
arboreal ( tree - living ) occupying tall , open and closed forest and extending along margins of riparian forests .
nocturnal , spending daylight hours asleep in tree hollows , dead branches , thick ferns , epiphytes or even fallen logs .
natural diet consists of leaves , flowers & fruit of native plants . capable of digesting leaves & fruits often toxic to other species . also eats insects , bird eggs and scavenge meat if available .
communication is via scent markings , deep coughing & hissing noises when encountering other individuals .
threats include ; land clearing & loss of habitat , and in urban areas road - deaths & dog attacks .
females may breed from 2 years of age but are generally more successful after the third and subsequent years .
a further 2 - 5 months is spent riding on the mothers back & suckling from her .
after weaning may persist in the area they are raised for a further 18 - 36 months .
human dwellings provide abundant warm , dry shelters , lots of available food plants from manufactured gardens and opportunity to scavenge from litter and rubbish bins .
hand feeding by residents and leaving domestic pet - food outside can also assist possums .
inspect your roof for signs of obvious signs of entry . access is often gained by broken tiles , lifting corrugated iron sheets , deteriorating timber eaves , loose guttering and poor workmanship by builders .
obvious signs include hair and urine staining . feacal matter may also accumulate directly below the entry point .
inspect the entire roof . possums may utilise more than one location and will look for other localities if the usual access is sealed .
place loosely
scrunched up
balls of newspaper in the entry of probable sites and inspect over a two day period to see which localities are being utilised . the paper will be either pushed out or pulled into the roof space .

all possums are territorial . let us make sure that they continue to have a place amongst us .
we urge that all industrial bins which all have lids are actually closed . it is extremely tempting for animals such as possums to take advantage of food left in bins , once inside they are not able to escape .

relies on sight , hearing , touch , smell , and taste . its whiskers enhance it ' s perception .
leaves , fungi , lichens , buds , fruit , and sometimes bark . acacia is an integral part of their seasonal diet , with different species of the plant consumed at different times of the year .
) and may also be taken by large snakes or raptors . the main threat to populations is human action – the clearance of land for forestry and agriculture .

having body symmetry such that the animal can be divided in one plane into two mirror - image halves . animals with bilateral symmetry have dorsal and ventral sides , as well as anterior and posterior ends . synapomorphy of the bilateria .
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature . endothermy is a synapomorphy of the mammalia , although it may have arisen in a ( now extinct ) synapsid ancestor ; the fossil record does not distinguish these possibilities . convergent in birds .
forest biomes are dominated by trees , otherwise forest biomes can vary widely in amount of precipitation and seasonality .
offspring are produced in more than one group ( litters , clutches , etc . ) and across multiple seasons ( or other periods hospitable to reproduction ) . iteroparous animals must , by definition , survive over multiple seasons ( or periodic condition changes ) .
the area in which the animal is naturally found , the region in which it is endemic .
that region of the earth between 23 . 5 degrees north and 60 degrees north ( between the tropic of cancer and the arctic circle ) and between 23 . 5 degrees south and 60 degrees south ( between the tropic of capricorn and the antarctic circle ) .
reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female .
