Forestry

Metsäkeskus in 2011: At fertile growing places significant part of seedlings suffocates to hay and coppice instantly at their first years without taking good care of early treatment. In seedling which has been left at care of nature, value of nursery can easily lower 40 % in few years. In future value of woods remains low, because log accrual of area stays lower than in woods were early treatments are made with care.

Forest income isn’t only calculated from table prices of stumps.Must take into account extra costs and risks!

After total costs of nursery’s set up (1500 / hectare) biggest expenses could be nursery’s replanting, repairing, necessary early treatments, clearance, fertilization, purchasingof newseedlings and wasted growth time.

 

Prevent ELK and REINDEER damages by TREETOP PROTECTOR treated by TRICO

Damage targets

The most serious damage caused by elks is targeted to seedlings of deciduous trees and pine, which lengths are 1-3 meters, but damages are also apparent in smaller nurseries. In elks winter nutrition most popular species of domestic trees are rowan, willows, aspen and juniper before birch and pine. Silver birch is more popular nutrition plant than downy birch. Elk eats seldom alder or spruce. Also most hardwoods and foreign species like larch are good enough for elks.

Progress of destruction

Typical for elk damages are that they recur annually in the same nurseries. In the worst case, the repeated destructions of nursery make it worthless.

Effect on tree

Elks break branches and top growths but also stems of thinnest trees. These damages leads to growth losses and quality defects. Eating of sidebranches andtearing of leaves can dry tree’s top growth. Damaging bark of even large aspens and young conifers by eating causes permanent trunk injuries. Damages are also composed by rubbing antlers and trampling youngest seedlings.

In experiment TRICO-repellent practically prevented eating of treetops and top branches of seedling. It also decreases considerably eating of side branches. With protection effect it’s also important that there is no other injurious effects on for example growth of trees. In protection experiment which was made in summer birch’s seedlings which was treated with Trico had developed normally and there was noaberrant defects in comparison to control seedlings. Based on these experiments Trico seems to be useful matter to protect seedlings of forest trees from elks both in winter and summer.
