GLAZE DAMAGE IN RED AND SCOTS PINE PLANTATIONS IN SOUTHEASTERN MANITOBA

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.

The Impact

The impact of a major ice storm in eastern Ontario on 28 pine plantations (red pine, Pinus resinosa Ait.; Scots pine, Pinus sylvestris L.; white pine, Pinus strobus L.; and jack pine, Pinus banksiana Lamb.) was examined for 4 years after the event. Degree of crown loss and tree mortality were quantified in relation to tree and stand characteristics (e.g., tree species, diameter at breast height (DBH), stand density, stand edge versus interior). We also tested whether salvaging damaged material reduced subsequent tree mortality. Jack and Scots pine were 2.5 times more likely to be damaged by the ice storm than were red pine and white pine. Overstocked stands, and stands with lower mean DBH, were most susceptible to storm damage. Trees were five times more likely to be damaged in the interior versus the edge of a stand, in contrast with previous findings in hardwood stands. In unsalvaged stands, ca. 75% tree mortality was observed in severely damaged trees (>50% crown loss) compared with ca. 45% tree mortality in salvaged stands. Properly timed thinnings to increase diameter growth and the removal of dead and dying wood from heavily damaged stands are recommended to reduce the long-term effects of ice storms.

Multiple regression equations have been developed to predict yield from young red pine and jack pine plantations. Data from 446 sample plots representing young red pine and jack pine stands located on the south shore of the St. Lawrence River between Quebec and Montreal were analysed. The red pine plantation yielded more than the jack pine. However, in plantation both species yield more than in natural stands. Taking into account the age and spacing of the sampled plantations, the equation obtained can provide information on yield of red pine and jack pine stands the maximum spacing of which is 3 × 3 m, up to the age of 45 and 35 years respectively. The equations will allow the construction of preliminary yield tables for both species.

Tree Performance

Abstract Several 5- and 6-yr-old red pine plantations in central Wisconsin were sampled to assess the performance of crop trees and the levels of competing vegetation. A simple tree class system was devised to classify the level of brush competition on a fixed area plot surrounding each sampled crop tree. The tree class was significantly correlated with several measured and derived competition variables, and was also strongly related with three tree performance variables: height, volume, and biomass. Tree Class 1, the lowest competition level, was associated with significantly greater tree heights, volumes, and biomasses for both age groups. Logistic regression equations were developed to derive a quantitative relationship between competition, as measured by tree class, and crop tree performance. Performance was judged to be either adequate or inadequate based on an arbitrary set of standards for both volume and biomass. From the regression equations, probabilities of successful performance were calculated. For volume index and biomass, the Class 1 trees, or the trees with the lowest levels of competition, had success probabilities ranging from 76 to 89%. For the Class 4 trees, or the trees with the highest levels of competition, success probabilities ranged from 3 to 16%. North. J. Appl. For. 12(3):101-108.
