Christmas Island Detention Centre

Broadcast on Saturday 4/5/2002

Summary:

This week on Earthbeat the endangered red crabs of Christmas Island face a new threat as the Federal government fast tracks a detention centre for Asylum seekers.

Transcript:

Alexandra de Blas: Hi, I’m Alexandra de Blas welcome to Earthbeat, environmental radio across the island continent.

THEME

.......But first to another island at the opposite end of the continent, Christmas Island off the north-west coast of Western Australia.

Peter Green: I think the environment is under assault from four sides. We have a space station, we have a detention centre, we have crazy ants, and we have mining proposals. I think the environment is under the most pressure it’s ever been under in its very short history of human occupation. Christmas Island is a very special place, it’s an oceanic island whose fauna and flora is relatively still intact compared to many other oceanic islands around the world. Now, we risk losing that special status.

Alexandra de Blas: That’s Dr Peter Green from Monash University. He’s talking about Christmas Island, a small dot in the Indian Ocean about 24 kilometres long and 7ks wide, where a new 1200 person detention centre is about to be built for asylum seekers. He’s been studying the ecology of the island for 14 years, and is worried the development threatens endangered wildlife like the famous red crabs, that annually migrate from the forest to the sea to spawn.

What’s controversial about this proposal is that normal environmental assessment procedures are being waived by the Federal Government to allow the project to proceed. It’s said to be of national significance, so Environment Minister, Dr David Kemp has used his Ministerial discretion under the Environment Protection and Biodiversity Conservation Act.

Wilson Tuckey is the Minister responsible for the new development.

Wilson Tuckey: The government has people parked in various localities in the Pacific, it wants to bring them at least back to countries where Australia has its own control, or localities, and as such we have to get on urgently. But please remember in this circumstance, we are actually erecting the detention centre on an area that’s designated mining lease, and has in fact been subject to some mining already.

Alexandra de Blas: The road to the detention centre from town will run along one of the key migration routes of the red crabs endemic to Christmas Island and the Cocos Keeling Islands; how will you minimise road kills, because this road to North West Point usually closed during the migration season.

Wilson Tuckey: Well in fact there’s been considerable success already proven by the appropriate measures, which we’re going to use, and that is tunnelling under the road. You do some fencing and you do some tunnelling and the crabs seem to be very comfortable with that arrangement, and they use it, so they don’t use the road, it’s not that long, and they will go under the road.

Alexandra de Blas: Each of those tunnels costs about $30,000 to erect, and where the crabs pass you need to construct one about one every 300 metres; so how many of these crab tunnels are you expecting to erect on the road to the detention centre to protect the red crabs?

Wilson Tuckey: Well they will be sufficient, and they’ve been factored into our costs, which are quite significant across the board, but I understand there’s some channelling that’s done also with fencing that assists in this process. The experiments have been done on the island and proved successful, and we are following that arrangement, and we’ve allowed enough money to do it.

Alexandra de Blas: The detention facility will be built on an old phosphate mine site, as you said, and it’s near an endangered Abbots Booby breeding colony, listed as a high priority for rehabilitation. What will happen to the rehabilitation once the detention centre is built? Will that still go ahead for the Abbots Booby?

Wilson Tuckey: Well rehabilitation is something that’s an ongoing process, both in terms of the old British phosphate workings which were never rehabilitated at the time, and of course the mining company today has an immediate obligation to rehabilitate their workings, so those projects outside the boundaries of the detention centre, will continue in the ongoing fashion. You just made mention of the endangered Abbots Booby, that’s a contentious issue. Admittedly the numbers are probably not the same as they were years ago, but some raise the question of whether that’s the availability of feed in the ocean, or whatever, there’s certainly –

Alexandra de Blas: But isn’t it –

Wilson Tuckey: Wait a minute! When I’ve finished.

Alexandra de Blas: Sorry.

Wilson Tuckey: There are certainly millions of trees available for them to nest in, and of course the other point that it’s time the community recognised in regards to this bird is, it’s called the Abbots Booby after a Mr Abbot, who first discovered it on Assumption Island, where it is still in residence, and we keep getting fed this misleading comment that this bird is unique to Christmas Island. It is not. The reality is that the bird had ample nesting sites, the area in particular that’s going to be used on this occasion is not generally suitable; yes, there’s the odd nest there, but most of them are further into the park, and it is generally, at the best, low scrub, and at the worst, just bare ground. Now you say the IUCN has listed this bird as endangered; I don’t think the evidence is there, but theirs is always a rather precautionary approach.

Alexandra de Blas: Wilson Tuckey, Federal Minister for Territories.

Dr Peter Green from the Centre for Analysis and Management of Biological Invasions at Monash University, has been studying the impact of the explosion of crazy ants on the island, which is thought to have been triggered by a series of very dry, hot years in the 1990s. He doesn’t share Mr Tuckey’s confidence that the plants and animals have the resilience to cope with new stresses.

Peter Green: We have many environmental concerns about the proposed detention centre. One is the endangered Abbots Booby. Abbots Booby is a sea bird that now nests only on Christmas Island, and it’s been red listed by the IUCN since the 1960s. There is a population of Boobys in forest right next to the proposed centre. What happens is, the wind comes across these old clearings, it becomes more turbulent in the canopy downwind, and that depresses the breeding success of Abbots Boobys. Now the clearing where the detention centre will be built has been slated as a high priority site for rehabilitation. So that site will now never be rehabilitated properly, instead it will have a detention centre there. Now the facts of the matter are these:

There are 2-1/2-thousand breeding pairs we think, of Abbots Boobys on Christmas Island. Now that does seem like a lot, but these birds breed at an incredibly slow rate, with an incredibly low rate of juvenile success. On average, a breeding pair takes 25 years to replace itself. Now that’s an incredibly long time, and a panel of experts is of the opinion that the biology of the species is such that any small perturbation to the population could push it to the edge of a decline from which it would never recover.

Alexandra de Blas: The road to the detention centre is one of the key migration routes for the red crab. Wilson Tuckey says the crabs will not be harmed by the centre, because they will build crab tunnels. How many of these tunnels would need to be built to make the road safe and how effective are these tunnels?

Peter Green: The tunnels themselves are very effective. We’ve seen that on one of the roads here that has three tunnels. They were built as part of the agreement for building the casino. So we know that these tunnels work, but they are expensive, and we do need lots of them. The main road out to North West Point will be closed during the crab migration season so that the traffic out to the North Western area will have to be re-routed a long way, if you like. Now the long way involves two major roads, crabs cross both of them and it’s estimated that we might need 20 at least of these tunnels, and each one cost about $30,000.

Alexandra de Blas: You came to Christmas Island to study the crazy ant, which is attacking the crabs; I believe the crazy ants have formed something called Super Colonies?

Peter Green: Yes. Normally with ants, you have isolated nests, each containing a single queen, and the workers from these isolated nests, even within the same species are aggressive towards one another. In a super colony situation, the nests are basically indistinguishable from each other, in that the worker ants from the nest basically co-operate in whatever they’re doing. The other key thing is that nests can have more than one queen. We’ve seen nests here on Christmas Island have more than 1,000 queens. But the end result is we’ve lost tens of millions of red crabs just in the last seven years. So in areas of super colony formation there are basically no more red crabs, they’re all dead.

Alexandra de Blas: How much red crab habitat have you lost?

Peter Green: Crazy ants super colonies currently infest around about 25% of the forest. The proportion of the crab population that’s been killed is quite likely to be a lot more than 25%.

Alexandra de Blas: It seems likely that the detention centre could be tied to the opening up of nine new phosphate mining leases. Why are you concerned about that, knowing what you do about red crabs and the forest?

Peter Green: The detention centre has been sited in a mine lease that is currently owned by Phosphate Resources Ltd. Now reasonably enough, they’re seeking compensation for the loss of that part of their lease, and there is talk that they’ll be compensated with land rather than dollars. Now currently they have a proposal before the government for nine new lease areas, totalling 448-hectares. Now 71% or 320 hectares of those proposed new areas is actually pristine, never been disturbed before rainforest. Now that’s a huge concern. Red crabs are the lynchpin of the ecology of Christmas Island, and there are significant numbers of red crabs living in these proposed mine leases, and they will be killed once the bulldozers go in to clear the trees.

Alexandra de Blas: Peter Green, from Monash University.

Wilson Tuckey strongly supports the bid for nine new phosphate mining leases to accompany the new detention centre.

Wilson Tuckey: The mining company would much prefer land swaps to financial compensation, and naturally so would the workers on the island, whose alternative employment prospects of course are very slim. I would like to think, and that would require approval of Parliament, that we can provide resource for lost resource, rather than further taxpayers’ money which can be better used in health and education and at the same time maintain the viability of the mining industry on that island.

Alexandra de Blas: But isn’t it a concern that red crabs, the endemic red crabs, have lost 30% of their habitat in the last nine years since the crazy ants have exploded, and they’ll lose more prime habitat if phosphate mining goes ahead on these new nine leases?

Wilson Tuckey: Well I disagree with your second claim. I don’t think there’s any substance to that argument whatsoever, but taking the other point, the crazy ant situation; of course the ant has been there apparently for many decades, but we’ve been quite successful with a baiting program distributed by hand, that has re-established the crabs immediately on that land that they were frightened off by the crazy ant and of course we have made resources, or indicated resources are available for a major bait distribution program by helicopter.

Alexandra de Blas: If mining goes ahead on these new leases, and new rainforest is cleared, what if that tips the crabs over the edge, wouldn’t that be a very serious matter?

Wilson Tuckey: Well of course it would. And that’s not going to happen. And the areas concerned are relatively small. I mean they’re only asking for areas that have previously been mined and lower quality ores have been stockpiled, so they’re not virgin rainforest and there is some virgin rainforest that could be included which is not presently in the park.

Alexandra de Blas: There are plans to build a space launch facility in the south of the island; how will the blasting and vibration affect the nesting birds and the fauna on the island?

Wilson Tuckey: I don’t think it’ll affect them at all. The area is to one end of the island, and unless a bird chose to fly through the rocket blast, I don’t think it’ll affect them at all. I mean animals do adapt, and there’s been a lot of mechanical activity on that island for generations now, and the birds are still there.

Peter Green: That raises many environmental issues. At the very least, again there’s going to be increased traffic on the roads going down to the proposed launch site. That’s I guess almost a minor concern against the emission clouds from the launches themselves, and the noise and the light, the site is literally within a stone’s throw of one of the major seabird nesting areas on Christmas Island. This area is full of Great Frigate Birds and Red Footed Boobys, and it’s possible that the launches of these very large Russian rockets are going to upset the birds quite considerably, and perhaps even force them to abandon that site.
