  Leuce-poplars (mostly white poplar and its natural hybrid grey poplar) are native tree species trough Hungary. They are covering more than 4.0 per cent of the Hungarian forested area (77 000 ha). The white (grey) poplars play a significant role in the forestation under sandy soil site conditions as well as they are of importance from nature conservation point of view as well.

  Long-term selection breeding work is going on at the National Agricultural Research and Innovation Centre Forest Research Institute (NARIC FRI), involving selection of fast-growing Leuce-poplar clones under dry site conditions.

  Micropropagation technology is relatively quickly spreading in forestry. In vitro multiplication of trees is applied mainly in fruit growing in Hungary, in case of forestry it is used mainly for selection breeding.

  This paper presents a short overview on the micropropagation trials with different Leuce-poplar clones and the early evaluation of the seedlings growing of the micropropagated clones/varieties.

  Game damage is an important problem in home wildlife management, because game managers pay more and more money for game damage year by year. Crop fields can do an appreciable part in reduction of game damages. The aim of the research is to survey the situation of domestic game damage and wildlife forage ground management. (Which are the most used plants on crop fields, how current are the using of seed mixtures, which are the most typical game damages, as well as which are the most applied game control methods?)

  It can be stated that the number of plant species sown on crop fields is quite low. Mostly corn and alfalfa are raised, though besides those many other plants are suitable to grow on crop fields. Rising value of game damage and big proportion of the agricultural game damage are well traceable from the questionnaires, too.

  One of the most important method of habitat development is wildlife forage ground management. Many plant species can be grown on the crop fields, as mixture, too. Use of seed mixtures has not been spread on the native wildlife forage ground, however there are many advantages of them.

  The aim of the research is to examine the role of the different plant species, seed mixtures in the game feeding, the savouriness of the plants of crop fields, as well as ascertain which seed mixtures are more suitable for wildlife forage ground management. On the basis of the investigation it can be find out that big amount of forage can be produced on mixed crop fields. Buckwheat, corn, rape, millet and white lupine proved to be the most beloved plants. It is suitable to make such mixed forages and use widely in the native wildlife forage ground management,

  – which assures better feed conditions for the game,

  – which are more attractive for the game and can draw away from other areas, so prevent, reduce game damage in forestry sector and in

  agriculture that is in the forest manager’s, agricultural and game manager’s interests, too.

  In Hungary black walnut (Juglans nigra L.) is one of the most valuable exotic tree species, mainly because of its excessively liked wood for furniture industry, that has fine tissue and singular colour. Generally it is established by seeding, it can be regenerated by coopice shoot well, but not by seeding in natural way. Black walnut crops regurarly from the age of 25–30 years and its rotation age is 75–85 years. Prosperous decorative shape of stem allows its using in tree plantings out of forests, too. In the future its role can increase mainly on good.

  Red oak (Quercus rubra L.) is our most important exotic oak species, that possesses growing culture with almost one hundred years in our country. Plantation character of red oak growing predominates principally by applied regeneration method (mostly artificial), regular planting space, applying defined method and planting space regulation system. Forest tending model for red oak, that considered stopgap in the native literature is intended to serving the latter. Especially important equation in the viewpoint of stand growing, that describes relationship of stem number (N, in hectare) and diameter at breast height (D1.3 in cm) is: N=e9.80220-1.12607lnD1.3.
