Plant Inventory

You have an obligation to restock woodland when the increment is not utilized

You have an obligation to restock woodland when the increment is not utilized. You are obliged to use established methods and tree species that are suitable for the site. Restocking can be done through planting, seeding or natural regeneration. In most cases you must perform soil treatment to get a satisfying result. All measures must be completed during the third year after harvest, at the latest. If the number of plants are too few after having regenerated, you have to restock the plants before it is too late. If, on the other hand, there are too many plants you might over time have to give plants space through a pre-commercial thinning.
UAV technology in combination with AI based Image analysis has proven an efficient toolset when it comes to assessing and managing forest plantations. The toolset can provide the owner with information about vital factors such as density, species and overall condition of the plantation.

Species Inventory

Forest Agencies sets requirements for existing forest plans for all forests

Forest Agencies sets requirements for existing forest plans for all forests. Today’s inventory methods in the field are in principle completely manual and are based on contractors’ experience, which is very subjective, time-consuming and expensive. Aerial photography with lidar is available for volume calculations, however it’s expensive and therefore long time between updates. Laser scanning is also monochrome (point cloud) which is why important information is lost and before/after documentation is, for forest measures, in principle impossible. Satellite data has the advantage of scalability but suffers badly from low resolution and is in practicality useless as decision basis for forest management.

With AI-based image analysis we are able to identify individual trees, their position, their species, stand height and forest density.

Storm felled forest detection

In the event of a forest fire

When severe, storms can cause extensive damage to forests by uprooting, wounding, bending and breaking trees. Storm damage management should involve a quick assessment to determine the extent of the damage, the need and potential for salvage, and woodland management efforts to return the woodland to a productive status. The potential for salvaging the damaged woodland parallels the marketability of non-damaged forests. Tree value is determined by species, size, and quality, the latter also affected by how long the trees are left unattended. Generally, loggers are not interested in removing small numbers of trees because of the costs of bringing in equipment and labor. There needs to be sufficient quantity as well as quality of timber to attract buyers. There is also an urgency, according to current research, regarding protection against harmful insects in the forest. Trees or tree parts that exceed five cubic meters per hectare risk being breeding material for harmful insects.

Spruce Bark Beetle

Accurate data at your fingertips

The spruce bark beetle is the insect that does the most damage to our spruce forests.
2.5 million cubic meters of forest infested in southern Sweden. The dry summer of 2018 led to major attacks.
Infestations of spruce bark beetles can be identified throughout the year, but it is especially important to keep an eye out for fresh damage from May to August. The Swedish Forest Agency recommends drones for help in the search for spruce bark borer infestations.
Identifies trees with rust-red tops or with flaked bark for signs of infestation.
