1.0 INTRODUCTION

1.1 Overview

The following report provides a technical summary of the analyses conducted on barren-ground caribou telemetry data for presentation in an atlas and for map products generated for the Government of Nunavut’s submission to the Nunavut Planning Commissions (NPC) land use plan. The maps and tables in this document are examples of the products to be included in the atlas being prepared for the Governments of Nunavut (GN) and (GNWT).

1.2 Study Area

The study area for the atlas consists of the annual home ranges for the ten barren-ground caribou subpopulations (Ahiak, Bathurst, Beverly, Bluenose East, Bluenose West, Cape Bathurst, Dolphin and Union, Lorillard, Qamanirjuaq, and Wager Bay) found within the Northwest Territories and mainland Nunavut (Figure1). The majority of the study area falls within the Northwest Territories and Nunavut, but also extends south into , Saskatchewan and Alberta. The NPC analyses were generated for the following eight subpopulations:

1. Ahiak 2. Bathurst 3. Beverly 4. Bluenose East 5. Bluenose West 6. Lorillard 7. Qamanirjuaq 8. Wager Bay

2.0 DATA LAYERS Different types of spatial data were compiled to cover the full extent of the study area. Telemetry data, showing the caribou locations over time forms the main dataset for the analyses. Base data (at various scales) and anthropogenic information were also compiled to facilitate the mapping and to provide a time snapshot of what the current conditions are on the landscape.

2.1 Caribou Telemetry Data

Telemetry points, collected at various intervals over the past 25 years, were supplied by the Wildlife Division of GN’s Department of Environment and GNWT’s Department of Environment and Natural Resources. Both satellite and GPS locations, from fourteen different datasets, were imported into an Access database and normalized into a common data structure (Table 1).

The data were then examined and processed as per the following tasks: • The non-unique animal IDs from different data sources were resolved. • The different sample intensities were normalized to only include daily locations (i.e., removal of multiple locations per day).1 • The data for each collar were assigned to the appropriate subpopulation using one of two methods: 1. If the collar was included in the 2010 or 2011 Nagy analysis (Nagy 2011) it was assigned to the same subpopulation identified by Nagy. 2. If the collar was newer than the Nagy analysis, its data wer examined spatially and assigned to the subpopulation that best fits its movement based on a visual inspection of the data. If there was any uncertainty to which subpopulation the animal belonged to, it was assigned to an ‘unknown’ class and not included in the analyses. • The locations for each subpopulation were assigned a season attribute based on date ranges specific to each subpopulation.

The resulting telemetry data provided the starting point for the density and key life cycles analyses described in Section 3.0. Table 2 lists the subpopulations with a breakdown of each of the data sources contributing data for that subpopulation, the number of collars and the date range applicable to each source dataset.

2.2 Caribou Seasons

The seasons identified in the Nagy analyses (Nagy 2011) were correlated for each subpopulation and grouped into nine seasons for this project: spring migration, calving, post-calving, summer, late summer, fall migration – pre-breeding, rut/breeding, fall migration – post-breeding, and winter. The date ranges defining the season for each subpopulation are outlined in Table 3. Based on a review of the movement patterns, some of the date ranges for Ahiak, Lorillard, and Wager Bay were refined from the Nagy seasons based on the animal movements.

Caslys Consulting Ltd. July 2015 6 Barren-ground Caribou Analysis Methods Summary

3.0 ANALYSIS METHODS The telemetry data were analysed for each season and subpopulation. Density maps, derived from a kernel density analysis on the location data (points), were developed for the calving, post-calving, summer, late summer, rut/breeding and winter seasons. Corridor (high movement rate) analyses were conducted on the paths (walk lines between locations) for spring, fall – pre-breeding, and fall – post-breeding migrations. The resulting derivative datasets were then used to define the core seasonal ranges. These analyses were developed separately for each subpopulation and the results merged together to derive a study area wide dataset depicting regional distribution. Where there is overlap the highest density took priority.

3.1 Migration Corridors The migration key life cycles represent periods of high movement. They occur in the spring when the caribou are travelling to the calving grounds and in the fall when they are travelling to their wintering grounds. A detailed analysis, based on movement rates, was conducted on each collar for each year to identify the actual start and stop dates for these periods. Yearly migration corridors were derived from transect kernel densities for individual populations for each of the migration seasons. The search radius for the corridor analysis was 20 kilometres, which is an estimate of the maximum line-of-sight that a caribou would have on relatively flat terrain (Caslys 2010). To bring the individual migration density layers to a common scale, they were reclassified into the utilization distribution classes used in the seasonal home range layers. Higher use areas, from a year-to-year basis, were determined through the addition of yearly corridor layers.

3.2 Kernel Density The density layers (based on a kernel analysis) were derived from the caribou telemetry point datasets to identify seasonal home ranges (the area the population occupies within the specified date range). The density analysis used a search radius of 11 kilometres. This distance has found to be the threshold for avoidance behaviour for caribou related to human disturbance (Boulanger, Poole, Gunn & Wierzchowski 2012). The density surface was then grouped into classes (80%, 90%, 95%, and 100%) based on the probability of finding a caribou in the range. These probability classes represent the utilization distribution within the seasonal home range.

Areas with a higher utilization distribution are less critical because they encompass a larger extent of the landscape. For example, within a home range there is a 100% probability of caribou being present but much of the range is not being heavily utilized at any given time. Key habitats are those with higher densities of caribou. They represent a smaller proportion of the landscape and, as a result, have lower utilization distribution values when compared to the entire home range. These smaller areas are where the higher densities of caribou are found during the specified season.

3.3 Core Seasonal Ranges Core seasonal ranges were determined for the each of the nine seasons for each subpopulation. The migratory seasons (spring and fall migrations) use the 80% utilization distribution boundary to define the core seasonal range. The other seasonal ranges are based on a modified version of the 95% utilization distribution boundary. To remove outliers, areas within the 95% class had to surround an area of higher density. The following geoprocesses were then applied to connect individual patches of habitat, yielding contiguous polygons:

• the individual polygons were buffered by a distance of 11 kilometres; • the polygons, together with the 11 kilometre buffer zone, were dissolved; and

Caslys Consulting Ltd. July 2015 7 Barren-ground Caribou Analysis Methods Summary

• a negative buffer of 11 kilometres was then applied to reduce the size of the polygon back to the 95% class extent.

3.4 Key Access Corridors

Key access corridors represent the core migratory ranges within the core post-calving range that fall outside the core calving range. These analyses were not generated for the Bluenose West, Cape Bathurst, or Dolphin and Union subpopulations.
