Abstract:

The European (EU) race of Gremmeniella abietina (Lagerb.) Morelet, the causal agent of scleroderris canker of conifers, is a damaging pathogen in pine forests. In North America, this disease is found in the northeastern United States and in eastern Canada. Results from surveys conducted across Canada since 1979 are updating us on where this disease is found. In Newfoundland, only the EU race has been recorded and it is restricted to the Avalon Peninsula Contrary to earlier reports in the Maritime provinces, only one pine plantation is infected by the EU race in New Brunswick.

Abstract:

Afforestation programs such as the one promoted by the EU Common Agricultural Policy have spread tree plantations on former cropland. These afforestations attract generalist forest and ubiquitous species but may cause severe damage to open habitat species, especially birds of high conservation value.

Abstract:

Depending on the mosaic of habitats that is created, forest fragmentation can reduce the abundance and diversity of forest birds. Temperate deciduous forests in South America are rapidly being replaced by pine plantations, causing changes in habitats for both breeding and migrant birds. We examined differences in avian species richness and abundance in three areas: a reserve with continuous tracts of native forest, forest fragments and pine plantations. Four species were negatively affected by fragmentation, with their abundance declining from continuous forest to pine plantations. Fourteen sp

Abstract:

The contribution of larvae of the European pine sawfly, Neodiprionsertifer (Geoff.), to litter fall and element input was determined in two contiguous 25-year-old plantations of Scots pine (Pinussylvestris L.) near Glencairn, Ont., in 1972. Tree spacings were 1.2 × 1.2 and 1.8 × 1.8 m. Tree diameters, numbers of needle-bearing branches per tree, and the number of larval colonies per tree were greater in the less dense plantation. On the other hand, there was no difference between plantations with respect to tree height, number of needles per branch, number of larvae per colony, or percent defo

Abstract:

Abstract It is more economical to manage red pine plantations in Wisconsin for pulpwood and sawlog combined rather than for pulpwood only, even on low quality sites. The most important factor influencing the economics of a plantation is land quality. On lands of site index 45 new plantations are unlikely to be economical, regardless of management regime. Lands of site index 60 to 75 have real rates of return of 4 to 5.5% per year and soil expectation values of $125 to $350 per acre at 3% interest. Planting densities of 8 by 8 ft followed by heavy thinnings at long intervals and short rotations

Abstract:

The diversity of foliar fungal endophyte communities was examined in three economically and ecologically important pine species in Scotland: Scots pine, Corsican pine and lodgepole pine. Two plantation sites comprising all three species were selected in climatically contrasting parts of Scotland and were sampled in late spring by collecting healthy needles from two age classes. Surface sterilisation was carried out before obtaining cultures of fungal isolates, and representatives of common sterile morphotypes were sequenced to determine taxonomic placement.

Annual levels of attack increased from 2 to 25% of the trees between 1987 and 1991 for the 110 plantations. Drainage and site quality index influenced the levels of attack.

We also included a number of covariates to account for their potential confounding effects, for example, the distance between each site and the nearesting hu

Five conifer plantations were sampled in northern New Brunswick for winter use by snowshoe hare (Lepus americanus). In 8-year old plantations winter hare pellets were 20 times more abundant in a jack pine (Pinus banksiana) than in a black spruce (Picea mariana) stand, which in turn contained 30% more pellets than a red pine (Pinus resinosa) stand. In two 13-year-old plantations, hare pellets were more abundant in a black spruce than a jack pine stand. Conifer cover 1-3 m in height influenced pellet densities. Conifer cover < 1 m in height did not influence pellet densities (winter hare use)
