Great Damage

In Austrian pine plantations in Serbia, the greatest damage is caused by the fungi Mycosphaerella pini, Sphaeropsis sapinea, Cenangium ferruginosum, Germmeniella abietina (in the mountain regions) and occasionally Armillaria spp., Lophodermium spp. (seditiosum, conigenum, pinastri) and Cyclaneusma niveum. In Scots pine plantations, the greatest damage is caused by the fungi Heterobasidion annosum (especially in plantations on sandy soils), Armillaria spp, Lophodermium seditiosum, L. pinastri, Cyclaneusma minus and Sphaeropsis sapinea. Damage caused by rust fungi (Coleosporium sennecionis, Melampsora pinitorqua and Cronartium flaccidum) occurs less frequently. In mountainous regions in Scots pine plantations, great damage is caused by Phacidium infestans, Lophodermella sulcigena and Gremmeniella abietina.

Scots Pine Stands

The  study describes the natural regeneration state of a forest on coarse sandy  soils. The natural regeneration was studied in three different ecological  conditions: in 30 to 60 year old Scots pine stands, in a 62 year old mixed  stand of pedunculate oak and red oak, and on the free field.     The analysis of the regeneration groups revealed that the first settler  maintained a dominant social position during the following years after the  settlement. The structural basis is consequently laid out early. This means  that the forest practice has to consider the very first phase of the  regeneration as determining for the following evolution of the regeneration  groups.

And Control

Fungus G. abietina is one of the most dangerous pathogenic fungi occurring in conifer plantations and Pinus species are especially at risk. Among pines, the most susceptible species is Austrian pine, and particularly endangered plantations are between 8 and 25 years of age. This fungus was found in Serbia and Montenegro on Austrian pine, Scots pine and spruce, but it was only in mountainous regions (Kopaonik, Vlasina, Goc, Durmitor). G. abietina forms both stages (anamorph and teleomorph) in its development. The imperfect form is far more significant for the infection process, i.e. the pycnidial stage and generally all infections are caused by conidia (pycnospores). Apothecia will be formed on the bark only two years after tree dying. In the severely infected plantations, all dead trees should be felled and removed, and the remaining trees should be treated with copper fungicides.

This study documents latent infection of Austrian and Scots pine tissues by Sphaeropsis sapinea, the causal agent of Sphaeropsis tip blight disease. Symptomless shoots from diseased or apparently healthy Austrian and Scots pine trees were cultured and analyzed for the presence of S. sapinea. Nearly half of the sampled Austrian and Scots pine trees that appeared to be completely healthy had detectable latent S. sapinea infections. More than half of the symptomless shoots on visibly diseased Austrian and Scots pine trees were also latently infected with S. sapinea. S. sapinea was isolated from symptomless shoot stems, needles, buds, immature cones, and male flowers. In symptomless infected shoots, the fungus was primarily associated with the bark and phloem tissues. Six isolates of S. sapinea from symptomless Austrian and Scots pine shoot tissues were pathogenic on Austrian pine seedlings in the greenhouse. The presence of S. sapinea in symptomless tissues of tip blight-diseased trees has important implications for disease management.

Permanent Damage

In November 1958, an ice storm caused severe bending of stems in young red and Scots pine plantations on the Sandilands Forest Reserve in southeastern Manitoba. A study was carried out to investigate the recovery of bent trees and to determine the extent of permanent damage in the plantations.Between 50 and 100 per cent of the trees in young red pine plantations were bent so severely that their tops were touching the ground. Scots pine plantations were less severely affected. However, both species showed considerable recovery and little or no permanent damage has occurred in plantations younger than 14 or older than 25 years of age. Approximately one quarter of the trees growing in two dense red pine plantations, 16 and 22 years of age, were judged to have been permanently damaged.
