According to the Finnish Meteorological Institute, the calculation error in the carbon balance estimates of northern ecosystems is significant, even of the same order of magnitude as the entire annual carbon balance of the ecosystem.

According to a new study, the carbon sinks in the northern regions have been calculated too small and the emissions too high. According to the Finnish Meteorological Institute, the calculation error is significant, even of the same order of magnitude as the entire annual carbon balance of the ecosystem.

To correct the error, the new study used a new method based on machine learning, which is already in use at the Finnish Meteorological Institute.

Vekuri says that the magnitude of the measurement error is a few tens of grams of coal per square meter.

– In swamps, fields and certain forests, the carbon balance can be several tens of grams per square meter. In these situations, a carbon emission can turn into a carbon sink. In addition, it is important that even larger carbon balance forests are measured correctly, says Vekuri.

A very rare recording was created when the crew of a helicopter returning from a mission tested a thermal camera near Turku Airport.

On Tuesday, the Border Guard’s Surveillance Flight Squadron released a clip recorded by a helicopter’s thermal camera, in which a lynx gives a ride to a lone wolf.

– It clearly makes physical contact, and you can see that the wolf is going really crazy. The ilves defends itself strongly by clawing and attacks as such, says a specialist researcher at the Finnish Natural Resources Agency.

A similar encounter has reportedly never been caught on video before.

– I don’t know anything similar. This is a very nice recording, Holmala marvels.

The radiation emitted by the capsule is life-threatening.

Australian authorities have managed to find a tiny capsule that disappeared in the Western Australian desert two weeks ago.

The capsule was found in a car equipped with a radiation meter, which was traveling on the highway at a speed of 70 kilometers per hour.

An unprecedented search operation was launched in Western Australia last week. Its target was a 6 by 8 millimeter capsule that had fallen from a car belonging to the Rio Tinto mineral exploration company. The size of the capsule can be compared to the nail of the little toe.

What made the capsule life-threatening was that it contains the element cesium-137, which emits beta and gamma radiation. The intensity of the radiation corresponded to ten x-rays per hour.

The Finnish Game Center is looking for new sites where wetlands can be restored for waterfowl. In the spring, waterfowl are waiting for 43 restored wetlands around Finland.

With the support of the Riistakeskus, tens of wetlands have already been renovated to improve the habitat of waterfowl. Most of the sites belong to private landowners who, for various reasons, wanted to establish a wetland themselves.

Renovated areas can be found in different parts of Finland. Among the 43 sites that have now been completed are, for example, a field area left for cultivation in Paltamo, a former peat production area in Tornio, drained forest land in Siikalatva and a dried pond in Oulaiin.

The goal of the project led by Riistakeskus is to protect declining waterfowl populations by helping landowners and other interested parties to establish, renovate and maintain suitable sites as nesting habitats for waterfowl.

As the project continues, the habitat work will expand and now we are looking for new sites to be renovated for planning.

Wolf DNA samples are collected from the beginning of November to the end of February. DNA analyzed from wolf droppings can be used to identify the wolf that left the droppings and the wolf’s territory.

Collection of wolf DNA samples is underway. According to the Finnish Natural Resources Agency, many samples have already been received, but more are still hoped for, for example, from the Kainuu area.

Wolf DNA samples are collected from the beginning of November to the end of February. DNA research reveals things about wolves that cannot be learned with any other method. With the help of DNA analyzed from wolf droppings, it is possible to identify the wolf that left the droppings and the boundaries of the wolf territory, and it is also possible to find out whether a wolf pair or a pack lives in the territory.

The results of the DNA sample collection are used in the annual wolf population assessment.

The information of the collection officers who receive the samples can be found at the Luonnonvaratieto.luke.fi service.

In Virkkula’s new tower, it is planned to use at least partially the materials of the current tower.

An allocation of 90,000 euros has been received for the renewal of the Lintulahti tower in Liminga, which will be used for the design and partial reconstruction of the tower. The work is carried out by the municipality of Liminga and Metsähallitus. The investment ensures safe and high-quality services for hikers in the future as well.

The Liminganlahti nature center recorded a record number of visits last year. The nature center presenting birds and wetland nature was visited more than 61,000 times.

The Liminganlahti nature center’s record number of visitors was influenced by, among other things, the revival of visits by school and business groups after the corona years. The popularity of domestic tourism was also still visible in Liminga. Similarly, events such as the Bird Photography Festival again attracted a large audience.

Metsähallitus and the municipality of Liminga have systematically developed the area of \u200b\u200bthe nature center over the past few years. Among other things, a new nature trail has been built there

The forest exhibition has been organized in the Joensuu region seven times before. Due to the corona, the exhibition was last held in 2019.

The Forestry Center of Finland and ProAgria Itä-Suomi will organize the Silva 2023 Forest Exhibition in Joensuu in the fall.

The previous Silva was organized before the corona in 2019. Pandemia postponed the organization of the next exhibition to this year.

The exhibition, free of admission, can be seen in Joensuu’s Laulurinte area on September 8 and 9. 25,000 visitors and 200 exhibitors are expected at the exhibition.

The central themes of the Silva 2023 Forest Exhibition are, for example, security of supply, forest bioeconomy, new innovations in wood, and the rise of nature tourism. The stage in front of Laulurinne will be used by the vocational college Riveria, Karelia University of Applied Sciences and Eastern Finland College for forestry education exhibitions.

At Birdlife Finland’s weekend event, in most of the participating Central Pohlian yards, the Great Tit and Blue Tit were seen most often.

Finland’s largest bird event Pihabongaus this time in Central Ostrobothnia gathered slightly fewer participants than last year.

Last year, in the vast Central Ostrobothnia, birds were observed from more than 550 yards, and this year from more than 350.

The information is still being updated.

In the area, the greatest number of sightings were made of the yellow warbler, titmouse, little sparrow and chaffinch. The most common spotted birds were the Great Tit and the Blue Tit.

Last year, there would have been more demand for the environmental support granted by the Finnish Forestry Agency than the allocated funds. The allocation for this year has almost doubled.

Forests were protected in Kymenlaakso last year with more than 130,000 euros. The forest owners signed a total of 24 environmental support agreements, which protected a total of 38 hectares of forest.

According to the Finnish Forestry Center, the demand would have been greater than the allocation, and some of the forest owners’ applications were transferred to the payment for this year. Environmental support and funding for nature management has been increased even more this year: now the funds are used for almost double the amount compared to last year.

The most common protected areas were lush and tree-filled forests, such as groves and cornfields, the immediate vicinity of small bodies of water, and dense forests of great diversity.

The environmental subsidy granted by Metsäkeskus obliges the forest owner to exclude the valuable natural environment from logging and forest management work for 10 years.

The trees will be moved to their final location at the northern end of the Hermann embankment between the lanes during spring and summer.

Trees have appeared in Helsinki’s Vallila Valley, bouncing off concrete cubes.

The trees are lime trees that have been removed from Mäkelänkatu in Kalasatama to Pasila to make way for the construction of the tramway, according to the City of Helsinki. The trees are attached to pedestals so that they can be kept upright while they wait to be moved to a new location.

The trees will be used as decaying trees in the green lane between the tram lanes.

On the Hermann beach road, the trees are installed on new stands. These stands go underground, so no trees remain in the concrete cubes.
