This case study explores the commercial development of black huckleberries (Vaccinium embranaceum Dougl.) in the Kootenay region of British Columbia. Black huckleberries have a long history of human and wildlife use, and there are increasing demands on the resource in the region. Conflicts between commercial, traditional, and recreational users have emerged over expanding the harvest of this non-timber forest product (NTFP). This case study explores the potential for expanding huckleberry commercialization by examining the potential management and policy options that would support a sustainable commercial harvest. The article also reviews trends and issues within the huckleberry sector and ecological research currently conducted within the region.

The current distribution of P. digoneutis in Canada shows that the parasitoid is now well established in eastern Ontario in parts of southern Ontario. In the northeastern United States, it took almost ten years before a significant impact of P. digoneutis was recognized and Lygus populations collapsed. Thus, it is hoped that a continuous growth of P. digoneutis populations Ontario will have a similar long-term effect and lead to an area wide reduction of the pest. This also suggests that ongoing work to encourage population build up and assess impact is needed. In addition, surveys in other parts of Ontario would help to identify areas where the parasitoid is not yet present, and releases would help to accelerate the dispersion and establishment of P. digoneutis.

Dietary inclusion of polyunsaturated fatty acid (PUFA)-rich plant oils is one approach to improving the fatty acid profile of ruminant meat and meat products from a human health perspective. Whole crop wheat silages represent a possible alternative forage to grass silage for beef production, however, they may adversely impact the fatty acid profile of ruminant muscle since grass silage is rich in C18:3n - 3. The first objective of this experiment was to investigate the relationship between an increase in the dietary supply of C18:2n - 6 from sunflower oil (SFO) and conjugated linoleic acid (CLA) concentration in the muscle tissue of beef cattle. The second objective was to investigate the effect of the basal forage type on the muscle fatty acid composition and its response to increasing inclusion of SFO. One hundred and five heifers were blocked according to initial bodyweight and assigned to one of seven silage treatments. The silage treatments were: (1) grass silage (GS), (2) whole crop wheat silage with 38% dry matter (DM) (W1), (3) GS and W1 at a ratio of 1:2 (DM basis) (WIGS) (4) GS and W1 at a ratio of 2:1 (DM basis) (GSW1), (5) whole crop wheat silage with 52% DM (W2), (6) GS and W2 at a ratio of 1:2 (DM basis) (W2GS), (7) GS and W2 at a ratio of 2:1 (DM basis) (GSW2). Within each silage treatment, S animals were assigned to one of three concentrate rations, differing in the content of SFO. The levels of inclusion of SFO in the concentrate were 0, 55, 110 g/kg concentrate. Inclusion of SFO in the diet led to an increase in the n - 6:n - 3 fatty acid ratio in muscle. In animals fed grass silage or mixed silages the n - 6:n - 3 ratio was lower in muscle compared with those fed whole crop wheat silages, with the exception of animals fed 55 g SFO/kg, for which feeding WIGS led to a higher ratio than W1. Other than the n - 6:n - 3 ratio there were no significant interactions between the effect of type of silage and the level of SFO on the concentration of fatty acids in intramuscular fat. Increasing the inclusion of SFO led to a linear increase in the CLA-cis-9,trans-11 and PUFA concentration in intramuscular fat (P < 0.001). This study confirmed the potential for modification, and improvement from a human health perspective, of the fatty acid composition of beef muscle by dietary manipulation. ?? 2004 Elsevier Ltd.

Field trials of 12 potato varieties across Canada, including a site in Williams Lake.

The concentration of prunasin, the cyanogenic glycoside in Sas- katoon serviceberry, was determined in leaves and twigs over a 12- month period. Eight shrubs were monitored, three of which were located in the ponderosa pine zone and the remainder in the Douglasfir zone. Qualitative tests indicated that the cyanide poten- tial of serviceberry persisted continuously at all the experimental sites in both leaves and twigs. Quantitative analyses showed that prunasin levels in twigs were substantially higher in current year's growth as compared to previous year's growth. The highest pru- nasin levels were obtained in new growth of leaves and twigs following initiation and and this potentially hazardous period for browsers is described. Shrubs yielded lower prunasin levels when they were associated with ground water indicator species. Saskatoon
