Puketi forest enviroMate100 possum control
Your funds directly enabling a demonstration of enviroMate100 alternative to aerial 1080 whilst reducing possums in Puketi forest.Northland
EnviroMate100 (a automated bait station) is being used in the centre of Puketi Forest to provide data "of scale" displaying that new generation possum control can be partially self funding through fur recovery whilst maintain forests with very low declining possum populations .
We will provide continuous control of possums within approximately 1200ha using enviroMate100 bait stations, cyanide toxin and traps. It is expected the impact of this possum control will filter outwards to reduce possum population over approximately 3000ha.
This operation initially requires 1 single visit every 14 days to each individual enviroMate100 to reload it with lure and toxin. At this time possum fur can be recovered.
Smaller scale operations suggest each externally placed bait station site will maintain catching 1 possum on average every 14 days whilst the internal area will become possum absent. It is hoped at the larger scale the internal areas will also eventually become depleted of possum residents.
A independent possum control contractor using enviroMate100 was successful in gaining 6% 5.3% and 4.7% BMI monitor solely with lure to pull possums over extended distances to be caught in leg hold traps, this was a TB free control funded operation. 15% BMI is what DOC target to enable biodiversity gains.
Our hope is to provide the validation and operation model for working in dense forest needed to update outdated trapping information of which suggest that trapping and ground control work is more costly and less effective than aerial delivery for the sustainable maintenance of conservation values. The promotion that fur recovery can now meet environmental requirements currently set by DOC whilst creating jobs in rural environments.
We wish to show case a different method of control and management system to achieve the desired outcome with no non target deaths.
Please note the resident possum population in this forest is presently uneconomic for a living wage to be made from fur collection using conventional trapping or poison application. DoC have declined development assistance since 2014. It was suggested we need to validate enviroMate100 technology at landscape scale, this has now been done by an independent contractor being successfully monitored in three separate contracts.
We seek partnerships with those who participate in fur recovery as they have the skilled, self motivated hardened workers to conduct large scale self directed predator control. We wish to maintain a living wage for these people.
Aerial application of toxin (once only application) currently costs around $38 - $56 per ha. We are offering to maintain a similar level of possum control but across the entire"year" for $40-50 per ha and ask you to contribute directly to provide this control.
It is expected fur recovered will finance the initial deployment of enviroMate100 into the forest but not the continued protection against reinvasion. We could also target rats and stoats as they are drawn to enviroMate100 activity. At present we are not enabled by DoC to use rat baits and would need take traps to site.
Another way to look at the cost structure is it costs $10 to carry each enviroMate100 onto site and $10.00 to remove again. It works for 14 days delivers toxins on the last day killing those possums that are visiting.
Every additional visit to reload at the same site costs $5.00- $10 per visit dependant on what goes in to it.
We wish to deploy and maintain 250-300 enviroMate100 in this operation. To do this with your help we require $1250.00 -$1900 every 14 days to maintain each site ($1-2 per ha per visit approx.)
Every additional $5 we receive we can return to service 1 enviroMate100 for another 14 day cycle of control against reinvasion. Sporadic fur recovery around the boundary will help fund the rest.
Eco-land will supply enviroMate100 and implement the work. Eco-land will recover fur to cover enviromate100 deployment and removal costs
We note Govt funding aimed at "alternative tools" to aerial control is not currently filtering to implementation efforts in the field. We have a proven successful system ready to operate but have not been enabled. We need your help to make this happen!
Use of funds
$130 maintains one enviroMate100 automated bait station onsite in Puketi for 1 year. This includes labour, lures, battery, travel and toxin. One single enviroMate100 controls 4ha for possums.

Lots has happened. Last week Line 3 opened for the first time. This being the boundary on the eastern side of the block. A further 20 enviroMate 100 at 100m down the line. These ran pre feed for the first 6 days then delivered toxin (cyanara paste) for collection of possum fur on the 7th day. A total of 27 possums skins were recovered along with 6 possums for plucking. Several units were one day out of time due operator error on install. They had not delivered the toxin so we expect higher numbers on these sites next Thursday when I visit and extend the line.
Last Tuesday line two was revisited in part, an area that has the original traps still in place. We reloaded the enviroMate to delivery with cyanara in 7 days and also opened the leghold traps, 2 traps on each site with a total of 34 traps and 17 enviroMate 100. On checking the next day and closing the traps we had caught 3 rats, 9 possums of which were recovered for fur.
Today we revisited the full line and reload with a cycle of 21 days pre feed with cyanara to be delivered on the last dish. I will plan to visit on day 19 or 20 to collect any further possums.
Previously I had loaded the enviroMate100 on this entire line with toxin to be delivered each day. This has been left for some time with no visits. Today we suggest an average of 2-3 carpet possums around each site. Nearly all units were perfectly cleaned with many having mice droppings in them. This method whilst successful displaying boundary control capacity has meant 90-135 (45 units) possums were killed over time in a random sporadic fashion but were not collected for fur....!
Thanks we will put your donation to good use. I heard today that bird song recorders have been placed with in the zone we are working to listen for kokako that may have extended their habitat range from the puketi forest trusts protection zone.......
Hi Thanks for listening to RNZ and supporting efforts in Puketi will keep you and others updated with news from the forest.
Hi That was really fast! Thanks for your support in making positive change in Puketi
Excellent THANKS!. Another effort will be made next Monday. A further 8 enviroMate100 units will be taken into the forest to complete the first loop. I await the required poison warning signs to be made, these will cost of around $250 for the four signs.
Thanks kindly, that is a nice surprise. Doc have issued the cyanide poison consent so the operation will now gain some speed. Enjoy knowing 12 ha of forest will shortly be controlled and maintained for possums by your donation until consent expires in September 2020.
