Thread: Virus

https://wordpress.com/post/killthatrabbit.me/329

I have been informed by a Farmer who's place I shoot that the virus has been released in the Central Otago area. About 2 kms up the road from where I shoot so it will be interesting to see how it affects the rabbit numbers and my shooting.
I don't know how accurate the information is but he reckons it spreads at 500 mtrs to 1 km a day.....

It will be interesting to see if the farmers have got any smarter than they have been when the first illegal release happened. Many sat back and did very little in the way of pest control and now have a problem again.
A few with fore sight saw it as a chance to get a big break on the problem and try and stay on top of it.

My moneys on the rabbits shrugging this off in 3-4 yrs. Can't just keep bringing in new virus's forever before something goes badly wrong and a strain mutates and jumps species.

Just got to keep smashing them even after the virus has been released. Farmers that do that will see results. If they sit back and think its the golden goose they'll likely get a surprise in a few years. The rabbit numbers down here in places astound me. My neighbor has taken about 14,000 of a place down the road since October.

my old easter bunny hunt crew very disappointed.
Notification of its release 2 weeks ago prompted the cancellation/postponement of the bunny shoot only 3 odd weekend from its happening

What is amazing is they are saying that they hope to achieve at least a 40 % kill on this new release. When I was still doing pest control work they always said you needed to be getting kill rates in the high 80 to 90 % to have any sort of effect on the populations. 40% will do very little except to promote increased breeding with the remaining population.
Back in the late 90's when it first hit my area in the BOP I had count lines established over 20km's of farmland and we counted the lines twice a year.
The year the illegal release was done I had counted close to 1100 rabbits pre the virus within a week it had spread through the whole area and when the post count was done I counted 32 rabbits.
We warned the farmers that these remaining rabbits would come back if left to there own devices, which they were and with a year and a half were back to pre virus levels. Problem now was you had rabbits that are resistant to any future releases. This is a different strain but 40 % is a pretty low kill rate I think. It will be interesting to see how it effects the populations over the coming months. One thing is for sure the rabbit will survive whatever man can throw at them.

It will be just another tool. I predict that it will have a good kill first time round if it is done right. Long term will stabilise out at around 40% annually. Remember councils don't want to get hopes up and need to keep farmers grounded in reality.

Farmers will have to stay on top of rabbits with traditional tools to maintain low populations. Those farmers that continued to spend on rabbit control through the 90's and beyond more than got their money back in increased productivity, that will be the same for this strain too.

Off to Alex this weekend, so will shoot a few and get a good feel for the "before" population.

The virus won't stabilise , as time progresses and the rabbit populations immunity climbs the kill rate will decrease. This has been shown from the original strain release and why they are now releasing a new variant .
I agree that done right the initial release should be effective.
Australia got the release last year and results have been mixed. Some area's reporting kill rates up to 80%, others around 40% and some showing very little result at all.

The problem is: they multiply like rabbits.

It appears that what I said earlier is coming true. 40 % isn't enough of a kill to have any effect at all. New born and young rabbits are born with an immunity to disease the blood tests we did after the release in our area back in the late 90's confirmed that. One sure thing is that a concerted effort using poison and shooting will be a definite way to help control rabbits. Who knows the powers to be may decide to bring back Pest Destruction Boards, doing a full circle.

No sign off it yet on the property I hunt.... will keep you posted.

Pregnant (and I think lactating) females if infected by the virus can pass on immunity to the young. Plus, I understand it, there needs to be a good fly population in order to act as a vector of the disease. Autumn is one of the few times of the year that rabbits are not doing what rabbits do best, whist's still having a "good" active fly population. So the window of opportunity is small to get a good establishment of the disease over a wide geographic region and hopefully a good first up kill over the next month or so.

Shame about the impact on the Easter bunny hunt, but I for one support the councils and farmers in this.

Now 3 to 4 weeks after the realease, depening on your location in Otago or Canterbury, the general feeling it that the Aussie suppliers pissed into a bottle and sent that over.

No dead rabbits reported at all in the Mackenzie. I sincerly hope someone will tell me something different because we need any new tools we can get. The 40% projected kill rate is underwelming but the hope was the new virus would kill of lot of already immune ones from the old, and start a leap frog effect between the two viruses.

Might be wishfull thinking but whatever happens they gave it a shot so thats ok but what next.

Pity is that a lot of farmers stopped doing any control works a while back, and now the virus doesnt appear to be killing anything , so now they realy have a very big problem.

Ive just ordered a lot of Pindone pellets for the winter.

They are releasing a virus in Hawkes Bay as well, I'm a bit guttered cause I am a keen rabbit shooter

@headcase, I am hearing the odd report of it starting to kick in. Someone up a local valley here reported it smelt like death, 50 % lower numbers than normal.
It maybe slowly gathering pace, as for the farmers who stopped doing pest control they deserve to have a problem , pest control down here is part of a good farming practice.
Being lazy pricks and hoping to get bailed out again by a new virus is bloody slack. I wonder how many will have learn't from the original release that if you get a break and do nothing then you will never get them under control.
There are enough control methods out there now, as stated in my earlier post I have seen it first hand.
Be interesting to see when / if it kicks off in the Mackenzie, good luck mate.

thanks for the good wishes Viper, I should clarify bout not doing any control work.. round here the cockeys were told to stop doing control work so the virus would have a better chance. The logic escaped me and on the properties that I do we never stopped, just kept on going, but for the people that were doing something and then got told to stop for a while, the slow start or non start to the virus release is very irritating.. rubs them right up the wrong way..

Fully concur with you on those that over the years have done SFA and hoped for the best. They deserved a hurry up long ago and always will because of the poor perspective they have on controlling numbers.
