Successful Mosquito Treatment
The treatment effort took place on May 28 and included a total of 166 ha, distributed in areas at Hallsjön, Storsjön, Vivastbo and Sevallbo. The effort yielded good results and we do not expect any hatching of flood mosquitoes in the near future.
The first mosquito control measure of 2020 will take place this week!
Local rain has created some flooding conditions in areas that are disjointed from the Nedre Dalälven. Therefore a treatment against these floodwater mosquitoes is planned for Thursday this week. The areas identified for control are Hallsjön in Huddunge, Storsjön in Möklinta, Vivastbo in Västmanland and Sevallbo in Gävleborgsland.
The appeal will not adversely effect this year's mosquito control
In lieu of the appeal against areas excluded from mosquito control, there was some uncertainty as to whether our permits would be delayed in the areas in which the Swedish Environmental Protection Agency had granted permission. Therefore, NEDAB had submitted to the Land and Environmental Court a request to honor the permits while deliberating on the particular areas in question. The Land and Environmental Court decided that the Swedish Environmental Protection Agency's decision shall apply immediately in those parts that have not been appealed. Thus, there is no obstacle to fight in the areas with permission if necessary.
Gävle Municipality has challenged the decision by the Swedish Environmental Protection Agency
An appeal by Gävle municipality to the Swedish Environmental Protection Agency has now been submitted to the courts for land and the environment. The municipality is challenging a part of the decision that denies treatments in the three Natura 2000 areas; Jordbärsmuren-Ålbo, Tjursöarkipelagen and Spjutholmen.
The current mosquito situation
As expected in the spring, mosquitoes begin to show themselves. These early season mosquitoes are those that overwinter as adult females. The large mosquitoes with striped legs and spotted wings can be a nuisance but only for a short period. We have also conducted field visits in both Nedre Dalälven and Klarälven and they both show low water levels with relatively dry floodplains. In some concentrated areas in Forshaga we did find snowpool mosquito larvae and pupae which will likely be in the air in 1-2 weeks. This species is not among the mosquitoes we seek to mitigate.
The target group for mitigation are floodplain mosquitoes which have laid their eggs and await a proper flood event. We continue to keep our focus on these conditions along the Dalälven and Klarälven.
The Environmental Protection Agency has made their decision!
On March 26, the Swedish Environmental Protection Agency granted an exemption which will allow us to conduct mosquito control along the Nedre Dalälven for the years 2020-2022. As in previous years we did not receive teh exemption for Natura 2000 areas Sputholmen, Tjursö archipelago, and Jordbärsmuren-Ålbo. The full decision along with appendices can found at this link to the Environmental Protection Agency's website (Swedish only).
Concurrently, Forshaga mosquito control also received an exemption but for the year 2020 (as applied for). All areas aside from the Natura 2000 area, Näs were approved. This decision can be found at this link to the Environmental Protection Agency's website (Swedish only).
The Nedre Dalälven application process is at the stage where the Swedish Environmental Protection Agency has now forwarded our request on to the central government (read here, Swedish only). Regarding Forshaga, our opinion on the stakeholder response to our application has been submitted to the Swedish EPA (read here, Swedish only). Following their review, we expect that our request for mosquito control with Forshaga will also be forwarded on to the central government.
Decision on mosquito control for 2019
On April 26th the Swedish Environmental Protection Agency approved mosquito control along the Nedre Dalälven.
We are now working in Forshaga Municipality as well!
For 2019 we have the assignment of preparing for treatments of floodplain mosquitos along the Klarälven in 2020. This includes collecting mosquito abundance data in the affected area. You can find more information in the menu under Forshaga or by clicking here.
We 're now looking for a mosquito control technician with start from February 2019.
