Book excerpt: Detailed account of the major forest insects and diseases of Newfoundland and Labrador in 1979, with a tabulation of the other noteworthy pests of the region. Collections totalled 987 insect and 150 diseases from 12 ranger districts and from visits and calls to property owners in the urban centres. Forest technicians also monitored, sampled and assessed damage caused by the spruce budworm. Sampling methods used during the summer and the results of monitoring budworm populations are represented. Assessment surveys were conducted from August to November to tabulate tree damage, egg-masses and overwintering larvae of the spruce budworm to forecast damage in 1980. Permanent sample plots on the Avalon Peninsula were remeasured for height and diameter and phenology plots in western and central Newfoundland were measured weekly to monitor spruce budworm development and tree growth. Shrew trapping was conducted in October to find the population levels of this animal and to monitor any changes during the larch sawfly outbreak. Temperatures and precipitation for the past 8 years are also given.

Book excerpt: Results of the 1978 detecting, monitoring, assessment and prediction surveys of forest insect and disease conditions in the 12 ranger districts on the Island and Labrador, as well as the pest conditions in the urban centres of the Island. Contracts were made with personnel of the Provincial and National Parks and industrial woods operations to discuss forest pest problems. Phenology plots were established in western and central Newfoundland in early May to check tree and spruce budworm development. Permanent sample plots were remeasured for volume and vigour 5 years after being established. Shrew plots were established at Halls Bay in central Newfoundland and St. Georges in western Newfoundland as part of the annual shrew census conducted in October.
