Description

Mortality assessments of mountain pine beetles are conducted annually between mid-May and mid-June to predict how successfully beetle populations may spread the upcoming year. The results of these surveys, combined with aerial surveys and ground assessments conducted in August/September, help the province prioritize areas for single tree treatment and timber harvest control tactics implemented in the fall and winter.

Expanded individual tree diameter prediction models from tree height and other variables

Description

Based on the nonlinear least squares method and nonlinear mixed-effects modeling technique, provincial and subregion-specific tree diameter prediction models were developed for major Alberta tree... More ≫

Description

Based on the nonlinear least squares method and nonlinear mixed-effects modeling technique, provincial and subregion-specific tree diameter prediction models were developed for major Alberta tree species. These models predict individual tree diameters at breast height from tree heights (varies by report). They can be used at both the population and plot-specific levels with varying degrees of accuracy. Different procedures for making the predictions under different circumstances are presented. Examples of model application are demonstrated based on real data.

Description

The owners and occupants of ag tourism ventures may be involved in activities ranging from operating a fruit farm business to offering horseback riding holidays for guests. No matter what the activity, biosecurity precautions are part of the common sense agricultural production management practices followed by ag tourism operators. Biosecurity measures can reduce the risk of introducing or spreading livestock and poultry diseases. This fact sheet outlines why biosecurity is important and who should practice biosecurity.
