Cone collection methods

Item consists of a training video which provides an overview of cone collection methods. The video details the natural circumstances, such as species characteristics, stand conditions, and crop abundance, that may affect cone collection. The video discusses four collection methods used in British Columbia to collect cones from trees: climbing, felling, aerial raking, and aerial clipping.

Cone crop forecasting

Item consists of a training video about forecasting for conifer seed collection. The video discusses the wide variety in seed-cone harvests from year to year and emphasizes the need to predict the size of a harvest. The presentation shows how to harvest and analyze the winter buds, and how to judge the effects of early summer weather and nutrition on the tree.

Cone crop surveys

Item consists of a training video on cone crop surveys. The purpose of these surveys is to identify good cone crops for the year's collection program and to provide data over time of cone crop periodicity within a particular stand. The video discusses how to plan a cone harvest and explains the equipment and methods to be used when judging whether a harvest will be feasible.

Lodgepole pine dwarf mistletoe

Item consists of an industrial video created to help forest workers detect and identify tree diseases in British Columbia and is part of a larger series on the subject. The video specifically covers the disease of dwarf mistletoe, a parasitic plant, on lodgepole pines and methods to control the parasite.

Seed evaluation

Item consists of a training video which provides a brief background on the biology of the seed cone, which may be useful to students as well as technical personnel. The video also shows how to select, harvest and evaluate samples.
