Feral horse management

The feral horse management framework provides options that consider the future of the species and the ecological integrity of their habitats.

Overview

Alberta’s feral horse populations range the Eastern Slopes of the Rocky Mountains between the Sheep and Brazeau Rivers.

Albertans have always felt a strong connection to feral horses, dating back to the role that their ancestors played in settling the west. Horses served vital roles in labour in the fields, providing transportation and improving the quality of life for settlers in Alberta.

In areas with high density feral horse populations, feral horses move from the preferred habitats with high availability of forage to other areas of the province, increasing the risk of unsustainable use of the landscape and putting pressure on plant communities as well as other grazing animals.

Alberta’s feral horse population is counted across 6 equine management zones: Brazeau, Nordegg, Clearwater, Sundre, Ghost River and Elbow. Minimum counts and distance surveys are conducted using helicopters for optimal maneuverability.

Release of domestic horses is illegal according to Section 16 of the Forest Reserves Regulation, part of Alberta’s Forest Reserves Act.

Feral horse advisory committee

The Alberta government is taking action to ensure sustainable management of feral horses. The new science-based management framework was developed with the input of the Feral Horse Advisory Committee comprised of stakeholders, subject matter experts, academic researchers and key organizations.

The committee provided valuable input into the feral horse management framework. Committee members will continue to help shape the Alberta government’s approach to feral horse management.

Impact on rangelands

Alberta’s public rangelands are productive ecosystems that support many different land uses including:

  • recreation
  • forestry and resource extraction
  • wildlife
  • livestock
  • feral horses

All these uses need to be managed to ensure public lands continue to provide important watershed protection, water filtration, carbon sequestration, wildlife habitat, and vegetation for wildlife and livestock grazing.

Public rangelands produce a finite amount of forage. Seasonal livestock grazing on public land begins in summer to protect sensitive rangeland plant species in the spring during the initial part of the growing season.

Rangelands become degraded if they do not receive sufficient rest or when cumulative grazing pressure by domestic stock, wildlife and feral horses exceeds the carrying capacity of the plant communities with an area. Without sufficient rest, especially during sensitive time periods, rangeland ecosystem health can deteriorate and lead to an increase in non-native plant species that may not have as high an ecological value.

Management framework

The feral horse management framework recognizes the presence of feral horses on the landscape.

Management frameworks are essential to protect Alberta’s wildlife, grazing animals and biodiversity. Without a framework in place, feral horses can negatively impact wildlife, birds, fish, cattle and vegetation.

All game and livestock species who utilize our ecosystems have management plans. From trout to bighorn sheep and grizzly bears, we develop management plans to ensure the ongoing sustainability of each species and the ecosystems in which they reside.

Feral horses are part of Alberta’s rich history. The objective of the management framework is to manage feral horse populations sustainably, while continuing to ensure wildlife and natural resources are protected.

Background information

Legislation

Provisions for the management of feral horses is regulated under the Horse Capture Regulation.

In the early 1990s, concerns about mistreatment of horses captured on public land led the Alberta government to create the Horse Capture Regulation under the Stray Animals Act. This regulation was developed to ensure humane treatment of feral horses during round-up and restricted the use of inhumane methods of capture, including the use of snares.

According to the Stray Animals Act individuals releasing animals will be charged for all costs of capturing, identifying, transporting and selling the animal, as well as any damages caused by the animal on private property.

Feral horse counts

2024 feral horse minimum count survey summary

Survey time period: January and February 2024

Equine management zones covered: Clearwater, Sundre, Ghost River and Elbow

Number of horses Counted: 1,478

Minimum counts provide a baseline of horses seen in preferred habitats. These types of surveys are conducted in each individual zone as funding permits with the intent of determining the number of horses on the landscape. It should be noted that there may be more feral horses than those observed through the minimum count.

Minimum counts:

  • 2013: 980
  • 2014: 880
  • 2015: 709
  • 2016: 854
  • 2017: 1,202
  • 2018: 1,712
  • 2019: 1,679
  • 2021: 1,314
  • 2022: 1,178
  • 2023: 1,428
  • 2024: 1,478

How feral horse surveys are conducted

  • Minimum counts

    Feral horse minimum count surveys are conducted using a helicopter for greater maneuverability. During the count, a detected group of horses are flown by until the observers can completely count the number of horses in the group. This total number is then divided up into adults, yearlings and foals.

    Two observers on the left side of the helicopter independently count and classify the animals to confirm group composition and prevent double counting. The pilot, situated in the front right seat, always manoeuvres the helicopter so that the horses will be on the left side of the aircraft if they were initially observed from the right side. GPS points and pictures are taken of each group to support classification.

    If the observers are unsure if a horse is a yearling or a small adult, it is classified as an adult to minimize the risk of overestimating the number of yearlings.

    Feral horses prefer grassy meadows, shrublands and newer (around 7 years old or less) cutblocks, resulting in relatively static flight paths over these areas.

    The flight paths may change slightly from year to year to ensure the department accurately captures feral horses’ preferred habitat as the landscape changes over time. For example, new cutblocks are established or existing cutblocks are no longer preferred as they mature and produce less forage, fires changing habitat availability and access routes.

    Flight paths are also adjusted to account for survey conditions, that is, low snow cover may require lines to be closer together to improve detectability. Large areas of recognized preferred habitat are flown in a grid pattern to cover the entire area. In areas with lower horse density, the grid pattern is not flown, and the focus is on areas preferred by feral horses.

  • Distance survey

    Since 2017, monitoring in the Sundre and Ghost River zones has been supplemented with distance sampling methodology. Distance sampling is a common method used for conducting wildlife surveys and provides more statistical rigour when considering population changes across years.

    Feral horse distance sampling surveys are also conducted using a helicopter. Analysis from the distance sampling method provides an estimated density and number of horses based on the number of horses observed during the distance sampling surveys. Distance sampling estimates only apply to the zones in which population sizes are sufficient for conducting distance surveys:

    Ghost River and Sundre Equine Management Zones (EMZs)

    These 2 zones have the largest feral horse populations. Before takeoff, Geographic Information System staff overlay randomly generated transect lines (up to 10 km long) to fly across the designated areas. Next, they remove 49% of these lines randomly, leaving 51% to be sampled.

    When flying, 3 observers are assigned specific areas within their field of view to look for animals – one person monitoring 50 m on both sides of the flight transect and 2 people looking >50 m up to 2 km on either side of the transect line.

    GPS points are taken on the flight transect at the moment when animals are detected and directly above the observed centre of the group. These points are input to computer software to create a detection function. A detection function provides an estimate of the number of animals and density on the landscape by using:

    • number of animals detected
    • distance to the animal when spotted
    • number of animals within each group

    The number of animals per group is important as it gives an actual estimate of the number of animals within an area with confidence intervals, which are used to determine if there are significant changes in the population.

  • Population metrics

    Adult-subadult-foal information is collected on minimum counts.

    There were 1,478 horses counted during the 2024 minimum count survey:

    • 1,309 adults
    • 166 subadults
    • 3 foals – foaling typically happens after surveys

  • Survey count summaries

    Survey counts are conducted in designated areas in the province. Alberta’s feral horse survey count annual summaries, flight tracks and horse observation points are publicly available.
