It\u2019s the last native mammal on the island, but the \u201cincredibly cute and fluffy\u201d Christmas Island flying fox is critically endangered with no recovery plan and severely outdated conservation advice.<\/p>\n

The flying fox is smaller and fluffier than many of Australia\u2019s mainland flying fox species, according to animal ecologist Dr Annabel Dorrestein, from Western Sydney University, who has studied the species for nine years.<\/p>\n

The bats are \u201cincredibly cute\u201d and \u201cchonky\u201d; a bit like teddy bears, Dorrestein said.<\/p>\n

Christmas Island, located 1,550km off north-west Western Australia, originally had five native mammals \u2013 two rodents, two bats and a shrew. The rodents disappeared in the early 1900s. The shrew has not been seen since 1985 and is probably extinct.<\/p>\n

In 2009, the Christmas Island pipistrelle \u2013 one of Australia\u2019s smallest bats at 3.4cm \u2013 became the first recorded extinction after the introduction of the federal Environment Protection and Biodiversity Conservation Act, which biologist Prof John Woinarski called the \u201cfirst irredeemable failure of that act\u201d.<\/p>\n

That leaves the Christmas Island flying fox.<\/p>\n

Weighing about 400g, with dark brown or black fur, flying foxes are considered a \u201ckeystone species\u201d due to their important role in pollination and seed dispersal, Dorrestein said.<\/p>\n

While population estimates are challenging \u2013 with flying foxes scattered across difficult-to-access major roosts and many smaller groups \u2013 there has been a definite decline since the first official counts, she said.<\/p>\n

In the 1980s, counts at Hosnies Spring, one of the island\u2019s two main roost sites, estimated about 2,000 bats. Dorrestein, who has visited that same site in recent years, said she would be lucky to count 400. \u201cThat\u2019s a huge, huge difference.\u201d<\/p>\n

The small size of the remaining population, and their reliance on a handful of maternity and breeding sites, make the bats susceptible to existing and emerging threats such as habitat destruction from mining and development, predation by feral cats and harassment by introduced pests such as yellow crazy ants.<\/p>\n

But, due to decisions under successive environment ministers, the species is Australia\u2019s only critically endangered mammal without a recovery plan. (The Nabarlek, which has no individual plan, is covered by one for five species of wallabies).<\/p>\n

In March, the then environment minister, Tanya Plibersek<\/a>, confirmed a decision under the previous government determining 176 species and communities would no longer require a recovery plan. Instead, an environment department spokesperson said conservation advice for the flying fox was \u201cin effect\u201d.<\/p>\n

Leading flying fox expert Prof Justin Welbergen said that advice, now more than a decade old, was \u201cseverely out of date\u201d and no longer a useful tool for managing the species.<\/p>\n

\u201cWe know that there are a lot fewer Christmas Island flying foxes than there were previously,\u201d he said. \u201cIt\u2019s really a time for action because we do not want to repeat the mistake that was made with the Christmas Island pipistrelle \u2013 that was effectively monitored to extinction.\u201d<\/p>\n

James Trezise, the chief executive of the Biodiversity Council, said recovery plans and conservation advice were critical for outlining the key threats, actions and responses needed to restore threatened species.<\/p>\n

\u201cIt\u2019s really important that we have some form of conservation plan for a threatened species and even more important if that species is a critically endangered one,\u201d he said.<\/p>\n

\u201cIt is equally as important to make sure that there are the resources available to implement those plans.\u201d<\/p>\n

Woinarski, based at Charles Darwin University, who lived on Christmas Island for two years, said it was a \u201cmagnificent place\u201d.<\/p>\n

\u201cYou walk in the forest and the trees above you are festooned with the nests of Abbott\u2019s booby, Christmas Island frigatebirds and a whole range of seabirds, calling all throughout the day and night in strange cacophony. The forest floor is full of red crabs like no other ecosystem in the world.\u201d<\/p>\n

While investment in research into the Christmas Island flying fox, and an advisory panel overseeing its management, was part of the legacy of the lost pipistrelle, he said, governments and land managers could not afford to be complacent about its status.<\/p>\n

\u201cIt still occurs only on one island. If a severe cyclone went through that one site and felled a whole lot of its important trees, and blew the bats off their roosts into the ocean, it could be gone in a second.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"It\u2019s the last native mammal on the island, but the \u201cincredibly cute and fluffy\u201d Christmas Island flying fox…\n","protected":false},"author":2,"featured_media":424037,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3843],"tags":[728,70,16,15],"class_list":{"0":"post-424036","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-environment","8":"tag-environment","9":"tag-science","10":"tag-uk","11":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115203448790818365","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/424036","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=424036"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/424036\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/424037"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=424036"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=424036"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=424036"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
