Opis:: The origin of the Norway spruce in the Gołdap Forest District from the north−eastern part of Poland was verified using the maternally inherited mitochondrial marker mt15−D02, which in Poland displays a geo−graphical specifity. We analyzed 730 trees from 29 populations and 21 plus trees. These populations included four reserves, four registered seed stand and 21 managed tree−stands. As a result of the performed analyses it was found that 8 out of 21 plus trees were non−native. Also 11 out of the 29 investigated pop−ulations contained trees of non−native origin. The scale of this phenomenon varies, although it encom−passes the entire region of the forest district.

Opis:: The forest area infected by mistletoe (Viscum album L.) in Europe has been increasing in recent years. The highest potential threat is posed by Viscum album subsp. austriacum, a parasite of Pinus sylvestris, and V. album subsp. abietis, a parasite of Abies alba. The paper presents a literature review related to biology, ecology and possible methods of limiting the negative impact of mistletoe on forest management. The vast majority of studies indicate that the presence of mistletoe negatively affects the growth as well as defensive and reproductive capabilities of trees. Due to the wasteful water management of the parasite, infected trees are particularly vulnerable to weakening during periods of drought. Mistletoe is a heliophilous taxon and forest breeding treatments should reduce light intensity in the forest canopy. Foresters should resign from leaving individual and group seed trees in forest stands inhabited by mistletoe after the cuts, because they may be a source of seeds for the parasite invasion to the neighboring stands. The most effective method against mistletoe is cutting out the infected trees. However, removal of individual trees in forest stand may be difficult, because the most often they are the dominant and hence the most vulnerable trees in the forest management. Mistletoe is also noticeable when the number of infected trees is already very large and they cannot be removed without disturbing the stability of the forest stand. Therefore, there is an urgent need to develop methods for monitoring stands for early detection of threat. Remote sensing methods can be very useful. It is also necessary to develop management strategies with mistletoe infected stands.
