Introduction

Over its decade-plus of operations, the ABMI has generated a comprehensive dataset on Alberta’s species, their habitats, and the extent and type of human footprint across the province. With this information, the ABMI has developed analyses to predict species' relative abundances and examine species' responses to vegetation and soil types, as well as human footprint in Alberta. These methods have been applied to hundreds of species; this profile provides summary results for one.

Habitat & Human Footprint Associations

Lodgepole Pine prefers to grow in well-drained, sandy loam soil. It is drought and shade tolerant and depends on wildfire for seed dispersal.

Species-habitat Associations in the Forested Region

Forested Region - Species Habitat Association Graph: Predicted species relative abundance (bars) as a function of vegetation and human footprint type in the forested region. Dots are added to forest types where harvesting occurs and show the predicted species abundance in cutblocks of various ages. Vertical lines represent 90% confidence intervals.

  • Lodgepole Pine relative abundance is highest in pine stands in the forested region; it is generally low across vegetation and human footprint types.
  • Lodgepole Pine relative abundance is much higher in young harvested pine stands compared to naturally disturbed pine stands in the forested region.

Relationship to Linear Footprint


Relationship to Linear Footprint in the Forested Region

Linear Footprint Graph: Species relative abundance predicted for habitat with no human footprint compared to habitat in which 10% of the area is converted to either soft or hard linear footprint.

  • Lodgepole Pine relative abundance is predicted to have no relationship with soft linear footprint and a slight negative relationship with hard linear footprint in the forested region.

Impacts of Human Footprint

Lodgepole Pine is commonly logged and is used for lumber and pulp, as well as other uses such as telephone poles, railway ties, and fuel.

Human Footprint Effects in the Forested Region

Under-footprint Sector Effects

Human Footprint Effects in the Forested Region

Figure: Under-footprint Effects. Percentage change in Pinus contorta relative abundance inside areas that have been disturbed by each sector in the forested region. Dot above bar indicates change in abundance is greater than 100%. Refer to value above or below the bar for the estimated under-footprint effect.

To understand how the Pinus contorta is impacted by specific development activities, the under-footprint figure shows how Pinus contorta relative abundance is predicted to change within each sector's footprint compared to the habitat it replaced (Figure: Under-footprint Effects).

  • Lodgepole Pine relative abundance is predicted to be lower than expected in all human footprint types, except forestry footprint, compared to the habitat each footprint replaces in the forested region.

Regional Sector Effects

Human Footprint Effects in the Prairie Region

Figure: Regional Sector Effects. Percentage change in Pinus contorta relative abundance throughout the forested region due to the respective footprints of each sector. Refer to value above or below the bar for the estimated regional effect.

The Regional Sector Effects graph shows the predicted change in the total relative abundance of the Pinus contorta across the forested region due to each sector's footprint, considering the: area of the footprint in the region, under-footprint effect, and habitat types impacted by a particular sector (Figure: Regional Sector Effects).

  • Lodgepole Pine total population effects for all industrial sectors are small in the forested region.

Predicted Relative Abundance

Lodgepole Pine is most commonly found in the Foothills Natural Region, but is also present in pockets of the Boreal Forest Natural Region.

Reference Conditions

  • The reference condition shows the predicted relative abundance of the Lodgepole Pine after all human footprint had been backfilled based on native vegetation in the surrounding area.

Current Conditions

  • The current condition is the predicted relative abundance of the Lodgepole Pine taking current human footprint (circa 2012) into account.

Difference Conditions

  • Lodgepole Pine relative abundance is predicted to be slightly higher under current conditions compared to reference conditions across much of the Boreal Forest Natural Region and some of the Foothills Natural Region.
  • Lodgepole Pine relative abundance is predicted to be lower under current conditions compared to reference conditions parts of the Foothills and Boreal Forest Natural Regions.

Other Issues

Lodgepole Pine is a target of the Mountain Pine Beetle.
