Subject: Case Study Report – Proposal: Bombus affinis Shelterbelt in the Drill Shed Meadow
Date: March 23, 2016
The attached Case Study has been prepared in compliance with the Shelterbelt Case Study Project, as assigned in week five of the Fleming College winter semester through the courses COMM 44 and ENVR 20. In the weeks that followed, the authors compiled in this report detailed observations, analysis, and shelterbelt designs to create habitat for the chosen species, Bombus affinis, within the assigned location, the drill shed meadow.
To thoroughly understand the ecosystem of the drill shed meadow, various information was gathered. Inventory was taken of the vegetation and wildlife present in the meadow, and climate data was both recorded and acquired through research. Samples of soil were taken, and their composition and compatibility analysed. Among these other observations, general notes were made detailing the local geography and other noteworthy factors to be considered.
Through study of both B. affinis and the shelterbelt site, a number of suitable improvements were planned. To contend with potential threats including nearby drilling activity and pedestrian traffic, the proposed shelterbelt would be positioned to protect as much land as possible. Being composed of nine rows and nine species, including eight flowering species, this primary planting would also provide an excellent source of food. Inclusion of other recommended improvements, such as wildflower plantings and artificial nests would further enhance the site.
Through the improvements recommended in this report, the drill shed meadow can be made into an ideal habitat for B. affinis. Additionally, the proposed planting would benefit various other native species, promoting increased biodiversity.

PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 3
AbstractOver the course of six weeks between February 9th and March 18th of 2016, the five authors
of this report created plans to install a shelterbelt supporting Bombus affinis, the rusty-patched
bumblebee, at the Fleming College drill shed meadow. The attached report, in its totality,
documents the research, discussion, and design stages involved in the development of this plan.
Shelterbelts are often considered synonymous with windbreaks, however they actually
incorporate many other elements. A windbreak is a row of trees or thick vegetation, planted for the
sole purpose of blocking wind. Shelterbelts perform this same function, but also serve to promote
biodiversity, providing food and shelter to a variety of native wildlife (Agriculture and Agri-Food
Canada, 2010). A successful shelterbelt must meet all the needs of B. affinis, and protect against any
potential threats such as predators, or starvation (COSEWIC, 2010).
The drill shed meadow itself is located just south of the Frost Campus windmill, found by
following the road south until it ends, and then passing a fence. A rectangular field measuring
roughly 102 by 73 metres, the meadow is covered primarily by grasses and other herbaceous plants,
with some scattered conifers and tall shrubs. It is bordered to the north by a community garden, to
the west by a drilling yard, and to the south and east by spruce treelines (Baker, Hennink, Huitema,
Jackson, & Wilson, 2016).
In the initial research stage, various field data was collected by group members. Included in
this collection were inventories of the vegetation and wildlife of the meadow, as well as soil analysis
and general observations. Outside of the field, climate data was retrieved, and group members
researched B. affinis and its needs on a broad scale (Government of Canada, 2010). Referencing all
of this data, a shelterbelt and other additions were designed, all specially chosen to be most
appropriate to both the conditions of the meadow, and the needs of B. affinis.
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 4
The group proposes a shelterbelt be planted along the north and west borders of the site,
composed of nine rows and nine species. Blocking the most exposed borders of the meadow, this
planting would reduce traffic through the area, especially combined with signage placed along these
trails. A central row of white spruce would disperse noise and wind originating from the west
(Agriculture and Agri-Food Canada, 2010; Government of Canada, 2010). The remaining rows,
consisting of flowering plants, provide a steady supply of nectar to bees in the region by blooming
throughout the active period of B. affinis (COSEWIC, 2010). Finally, the group recommends the
installation of complex artificial nests, designed to provide ideal habitat for Bombus species and
protection from predators (Lye, 2009).
Through execution of the plans outlined in this report, the drill shed meadow can be converted into
a productive, diverse ecosystem not only for B. affinis, but for various other native flora and fauna
species.

PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 6
Introduction
The site assigned, plot A, is better known as the drill shed meadow. Located on Fleming
College’s Frost Campus, it is found south of the community garden, and east of the drilling lot. The
meadow is rectangular, measuring 102 by 73 metres, totalling in .74 hectares. Bordering the
meadow to the north, west, and south are foot trails, most heavily trafficked to the north and west
(Baker, Hennink, Huitema, Jackson, & Wilson, 2016). The site is within the Saint Lawrence Lowlands,
and as such local bedrock is composed of sedimentary limestone and shale. This bedrock is
weathered easily, and provides rich, thick soils that sustain plant life very effectively (Luloff, 2016).
The soil within the plot was found to be a permeable sandy clay loam in the A horizon,
followed by a B horizon of silty clay. In combination, these two layers give the meadow a mildly
moist topsoil, which then gives way to truly moist soil conditions (Baker, Hennink, Huitema, Jackson,
& Wilson, 2016). The existing vegetation is primarily herbaceous, with a few trees and tall shrubs
scattered throughout. At both the eastern and southern borders of the site, grown spruce treelines
provide some shelter. In the southern ranges of the plot, what appear to be bur oak saplings are in
the early stages of reclaiming the meadow (Baker, Hennink, Huitema, Jackson, & Wilson, 2016).
Climate data recorded from Frost Campus reveals that winds in the region tend to originate
roughly from the west (Government of Canada, 2010). With no protective treeline or other cover to
the west, the meadow is quite strongly impacted by these winds. Excessive winds can negatively
impact life in a region, causing soil erosion, vegetation damage, or otherwise disrupting wildlife
(Luloff, 2016). The hardiness zone of the region is 5a, and directly impacts which types of plants can
succeed in the meadow.
The focus of all the proposed changes outlined in this report is Bombus affinis, commonly
known as the rusty-patched bumblebee. A highly endangered insect, B. affinis were once common
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 7
across Southern Ontario, but in recent years have disappeared across the province (COSEWIC, 2010).
Since the year 2000, only scattered individuals of B. affinis have been documented, such as the
female worker shown in Figure 1. Among Ontario’s most important native pollinators, B. affinis feed
from and advance the reproduction of thousands of native flowering plants (Government of Ontario,
2015). Like most Bombus species, B. affinis nest almost exclusively in abandoned underground
burrows, with their queens also overwintering underground (COSEWIC, 2010).
Figure 1 – Female B. affinis worker, among the only individuals left in Ontario (Colla & Ratti, 2009)
To attract and support a population of B. affinis in the drill shed meadow, the group
proposes the installation of the shelterbelt design included in this report. Shelterbelts are often
considered synonymous with windbreaks, however they actually incorporate many other elements.
A windbreak is a row of trees or thick vegetation, planted for the sole purpose of blocking wind.
Shelterbelt fulfill that same role, but are also carefully designed to promote biodiversity, providing
food and shelter to many different species (Agriculture and Agri-Food Canada, 2010).
To shelter the interior of the meadow, the proposed shelterbelt will follow the north and
east borders of the meadow. Consisting of nine rows including one of white spruce, it will provide
year-round protection from wind and other disturbances (Agriculture and Agri-Food Canada, 2010).
To provide food for B. affinis, it will incorporate eight carefully selected native flowering plants, as
well as others throughout the meadow (Chan, 2012). Finally, to ensure B. affinis can find a home at
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 8
the site, specially designed artificial nests will be installed across the meadow, incorporating
materials already present on site to provide maximum shelter from predators (Lye, 2009).

Species DescriptionIn order to recognize the success of the proposed shelterbelt, one must first be able to
identify Bombus affinis, also known by its common name, the rusty-patched bumblebee.
Identification of B. affinis is possible through three types of bee: a queen bee, a female worker, or a
male bee. Images of these three variants can be found in Appendix A.
Figure 2 – Bee anatomy, note T1-T6 representing tergites that make up the abdomen (Bumble Bee Watch, 2016)
B. affinis workers and males are both distinguished by their unique rusty patch, found on the
second tergite of their abdomen (see Figure 2), and bordered by a pair of yellow tergites (Wildlife
Preservation Canada, 2016). B. affinis queens are considerably larger than workers or males, and
lacks the rusty patch which is replaced by a pair of conjoined, yellow tergites (Wildlife Preservation
Canada, 2016). Other than the namesake rusty patch, B. affinis are distinguished from similar
Bombus species by short, dense black hairs covering their back (Wildlife Preservation Canada, 2016).
B. affinis have the longest annual cycle among bees in eastern North America, emerging in April and
active into October (Wildlife Preservation Canada, 2016). They are also, however, on the brink of
extinction, with only three B. affinis documented in Canada within the past 10 years, making them
the first federally listed endangered bee species in North America (Wildlife Preservation Canada,
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 10
2016). The primary cause for their decline as a species is generally considered to be related to
pesticide use, as the dramatic decline observed in populations over the past 30 years is too sudden
for predation, competition, or habitat loss (COSEWIC, 2010). The specifics of the decline of B. affinis
remain unknown.

Methods and Results
Wildlife Inventory
Over the course of two weeks, and again immediately before finalising the report, members
of the group surveyed the drill shed meadow to collect information on what kinds of wildlife inhabit
the site. Five categories of life were recorded, based on scientific class: birds, mammals, reptiles,
amphibians, and insects. Whenever an animal or signs of an animal were observed, the group
members making observations would record the sighting in the appropriate category. Data was
recorded at varied times throughout the day, with the intention of revealing the full scope of life
present in the meadow. By cataloguing all wildlife present in the meadow, the group hoped to
identify any predators or threats to B. affinis. As the survey was conducted in the winter, mammal
tracks could easily be spotted in the snow, however the inhospitable weather left almost no wildlife
to be observed. No signs of reptiles or amphibians were found, although signs of insects and their
nesting were noted, especially in warmer weather. Group members also observed several bird calls,
and some red squirrel activity was recorded near the eastern treeline (Baker, Hennink, Huitema,
Jackson, & Wilson, 2016). All wildlife inventory data can be found in Appendix B. The wildlife
observed were not predators to B. affinis, however, given the unfortunate timing of the survey, the
presence of predators in warmer seasons cannot be known for certain (COSEWIC, 2010).
Vegetation Inventory
Vegetation inventory of the meadow was taken, with group members surveying three 10 by
10 metre plots measured out within the assigned area. A Daubenmire sampling tool was used to
determine the composition of the area’s groundcover, as shown in Figure 3. Within each plot, group
members cast the Daubenmire tool at random, and then studied the vegetation found within the
tools borders. Vegetation within the tool was counted under the categories of grass, moss, flowering
plants, and other. The group also took inventory of woody plants, determining the percentage
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 12
coverage of shrubs, coniferous, and deciduous trees within each plot, and the woody plant
composition of the meadow as a whole. All vegetation inventory findings, woody plants figures, and
Daubenmire sampling documentation can be found in Appendix C. The meadow was found to
contain some mixed woody plants, but is mostly dominated by herbaceous cover. Also noted were
two existing tree lines along the south and east borders of the meadow which consist of fully-grown
coniferous trees (Baker, Hennink, Huitema, Jackson, & Wilson, 2016).
Figure 3 – Daubenmire sampling tool, shown in plot 1 (Baker, Hennink, Huitema, Jackson, & Wilson, 2016)
Knowledge of vegetation within the plot will play a key role in creating a habitable space for
B. affinis, as their primary food source are flowering plants. In order to most effectively establish a
healthy population of B. affinis, a shelterbelt must be designed incorporating great diversity in trees,
shrubs and grasses that will bloom and be pollinated at various times. Meeting these criteria, the
shelterbelt will provide an appropriate food supply, a vital component of a successful habitat for B.
affinis (COSEWIC, 2010).

Soil Analysis
During the investigative period, research was conducted on the types of soil that are found
in the drill shed meadow. Through knowledge of the area’s soil conditions, the group can more
effectively select the vegetation composing the proposed shelterbelt, and determine what changes
to the conditions, if any, are necessary. Furthermore, soil analysis would allow the group to better
recognize environmental challenges that might impact the success of the shelterbelt design.
Complete knowledge of the region would allow changes to be made, with the purpose of ensuring
the effective progression of plans to develop a habitat suitable for B. affinis.
Figure 4 – Soil profile, shown from sample hole #1 (Baker, Hennink, Huitema, Jackson, & Wilson, 2016)
Group members surveyed within a 10 by 10 metre plot measured out using a 30 metre tape,
the first of the three plots used in vegetation inventory. Once the plot had been marked, three
points were chosen to be augured, situated a triangular pattern at a distance of one metre apart.
Each of these three points was to be analysed separately, with the aim of providing varied sample
data on the meadow’s soil conditions. The ground was cleared of any grasses or debris, and the
auger operator used a hand auger to extract soil samples. As shown in Figure 4, once extracted the
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 14
sample was laid on the ground alongside a metre stick to create a visual representation of the layers
and their depths. The hand auger was then returned to the hole, repeating the process until the
hand auger operator could no longer dig due to obstruction (i.e. rocks) or until the auger had
reached its maximum depth of approximately one metre.
Through the aforementioned measurements, group members concluded that both the A and
B layers reached considerable depths, as it was not possible to collect samples of the C layer even at
the augur’s maximum depth. See Appendix D for depths of soil layers and samples collected.
Finally, soil samples were analysed using the ribbon test method, and a soil classification key
was consulted to determine the qualities of soil found in the drill shed meadow (Luloff, 2016).
Through this test, it was determined that the A layer in the drill shed meadow consists of a sandy
clay loam, which is most suited to a variety of field plants such as those already present at the site.
Contrastingly, the B layer consists of silt clay, more water-retaining soil suitable to another variety of
local plants. The colour and moisture levels of both layers were also recorded, with the B layer being
notably more moist, and therefore able to support plants requiring moist soil conditions. See
Appendix D for soil classification findings.
Further Site Observations
In combination with other observations, group members also recorded the temperature,
precipitation, and wind speed/direction of the meadow. Recording of the local weather, in
combination with government weather records, would allow the group to choose which plants to
introduce in the interest of both plants and bees (Government of Canada, 2010). Information
gathered concerning wind directions, in combination with other site observations, would also
determine the orientation and placement of the shelterbelt design within the meadow. See
Appendix E for climate data.

Figure 5 – Drill shed meadow and surroundings; note the meadow boundary in yellow, adjacent drill lot in brown,
community garden in blue, bordering pathways in red, concrete block clearing in black, and limestone debris in white
(Baker, Hennink, Huitema, Jackson, & Wilson, 2016; Google Inc., 2016)
Additionally, general observations were made, noting various other factors that had an
impact on the site, many of which can be found in Figure 5. This general information was among the
most important to gather, as it would reveal both potential challenges and boons to shelterbelt
design. The meadow was paced out, and measured to be roughly 102 metres north to south, and 73
metres east to west, equating to 7400 square metres of land, or 0.74 hectares (Baker, Hennink,
Huitema, Jackson, & Wilson, 2016). As this is slightly smaller than the one hectare recommendation
for a wildlife shelterbelt, it was decided that the shelterbelt should protect as much of the meadow
as possible (Agriculture and Agri-Food Canada, 2010). Group members noted a community garden to
the north, which could provide pollen and be a food source for the bees. Intense drilling activity was
observed on the drilling lot to the west, which could potentially disturb bees and other wildlife
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 16
within the meadow. Further potential disturbances were noted along the footpaths to the north and
west, where traffic of humans and dogs was seen, as well as on the meadow itself. Within the
meadow itself, group members observed a path entering from the west, and leading to a less
vegetated area and a pile of large concrete blocks. As these blocks were very heavy, the group
believes they were moved down this path with machinery, which could greatly disturb wildlife in the
region, and should be considered in the shelterbelt design. Finally, just north of this clearing, a ridge
of dirt and limestone blocks was observed, as shown in Figures 5 & 6 (Baker, Hennink, Huitema,
Jackson, & Wilson, 2016). Given that B. affinis are known to nest in natural crevices, the group
decided that the limestone blocks present in this area could be moved and repurposed as potential
habitat for the bees (Hatfield, Hoffman Black, Jepsen, Mader, & Shepherd, 2012).
Figure 6 – Drill shed meadow, note the limestone ridge in the centre (Baker, Hennink, Huitema, Jackson, & Wilson, 2016)
After completing initial observations, group members returned to the site each week, with
the exception of the week eight break, to photograph the area. By creating a log of photographs
over time, the group could observe changes in the meadow, or notice consistencies over time. The
meadow was photographed from all four corners, with group members trying to capture the same
angles and locations each week. One such series of site photographs can be found in Appendix F.

Results
The data collected indicates little to no change in topography across the plot, the majority of
which consists open grasslands. The southern and eastern borders of the plot are lined with conifers,
largely white spruce, which already act as an aid to block wind and noise, as well as deterring traffic
through the area. The inner boundary of the meadow is composed of over 80% herbaceous
vegetation, with some sparse tree cover as well as what appears to be a small plot of newly planted
bur oak trees in the south end. A variety of moss underlies the tall grasses, thriving in the shade
(Baker, Hennink, Huitema, Jackson, & Wilson, 2016).
Soil conditions were found to be consistent throughout the flat, plain-like meadow. The site
is in the Saint Lawrence Lowlands, and sits atop bedrock consisting on limestone and shale (Luloff,
2016). As these materials are easily weathered, soils were found to be thick, and favorable for most
of the tree and plant species to be brought in for the use of the shelterbelt (Baker, Hennink,
Huitema, Jackson, & Wilson, 2016). Given the success of both coniferous and deciduous trees within
the plot boundaries, and the observed soil conditions, the maples and spruce selected for the
shelterbelt are sure to thrive.
Wildlife observations catalogued indicated that the activity in the plot was minimal, as expected
given the inhospitable winter weather. Most birds observed were not found nesting in the meadow,
but rather flying over top, with some song birds perching within the eastern tree line. There were no
bees sighted in wildlife observations, though this was expected, as B. affinis is not active during the
winter months (COSEWIC, 2010). Observations were made on a third, warmer day once snow had
melted in an effort to document wildlife emerging in the warmer weather. Some insects were
observed, mostly arachnids and a cricket, common insects to be found in grassland conditions
(Baker, Hennink, Huitema, Jackson, & Wilson, 2016). In summary, wildlife in the region was sparse,
but what was documented poses no threat to B. affinis, and stands to benefit from shelterbelt
planting.
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 18
DesignBombus affinis is considered a generalist species, a fact that can be observed through its
broad range and varied habitats. Specifically considering nesting habitat, B. affinis are most
commonly found to nest underground, primarily in abandoned burrows, such as those of rodents
(COSEWIC, 2010). Referencing the projected ranges of numerous burrowing mammals, a variety of
burrow-creating candidates should be active in the area, especially following the shelterbelt
installation (Dobbyn, 1994). Given these characteristics, the drill shed meadow can be considered a
habitable space for B. affinis prior to shelterbelt installation, allowing design focus on other factors.
As one might expect, the most important factor to be considered in shelterbelt design is the
sourcing of food, namely flowering plants. B. affinis are active between the months of April and
October, and require constant access to food to survive. As reproduction towards the next
generation of bees does not occur until the end of this period, a small disruption in food source can
wipe out a colony (COSEWIC, 2010). To most effectively support pollinators, the shelterbelt must
contain a diverse selection of trees, shrubs, and grasses with varied bloom periods. It is also
important to give consideration to other factors, such as drought and disease within the plants,
which might disrupt or starve growing bee populations (Agriculture and Agri-Food Canada, 2010).
As a secondary objective, a shelterbelt planting should aim to deter human activity through
the area, especially heavy machinery from the adjacent drilling lot (Baker, Hennink, Huitema,
Jackson, & Wilson, 2016). Overly trafficked areas are prone to numerous issues, for instance over-
compaction of soil, damage to vegetation, or even destruction of nests. These concerns extend to all
life within the plot, supporting increased biodiversity across the sheltered area.
Finally, in addition to the primary shelterbelt planting, it is proposed that additional
wildflowers be planted, and artificial nesting spaces constructed. With these further improvements,
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 19
the meadow may more reliably meet the food, nesting, and overwintering needs of B. affinis
(Hatfield, Hoffman Black, Jepsen, Mader, & Shepherd, 2012).
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 20
Primary Planting Specifications
The primary planting of this shelterbelt will consist of two multi-row plantings, running from
the northeast and southwest corners of the plot, and extending to merge near the northwest corner,
as shown in Figure 7. In the northeast and southwest corners, the line of the proposed shelterbelt
will meet the existing treeline closely, limiting wind funnelling through end gaps (Agriculture and
Agri-Food Canada, 2010). With this two legged design, this shelterbelt can effectively disperse noise
and wind, both largely originating from the west (Government of Canada, 2010). Additionally, these
two edges of the meadow are its most open and travelled borders, given the southern and eastern
treelines (Baker, Hennink, Huitema, Jackson, & Wilson, 2016). By planting in this manner, traffic into
and around the meadow can be deterred, to the benefit of the protected region.
Figure 7 – Shelterbelt location, note the plot boundary in yellow, central spruce row in green, maple rows in red, and replaced topsoil + outer rows in brown (Baker, Hennink, Huitema, Jackson, & Wilson, 2016; Google Inc., 2016)
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 21
To maximise diversity within the aforementioned planting, the shelterbelt will consist of a
central row of white spruce, flanked on either side by four rows of decreasingly sized flowering
plants. While they do not provide food for bees, the central spruce trees are important to the
sheltering characteristics of the shelterbelt, and as they do not shed in winter, they fulfil this role
year-round. Between rows, plants will be spaced diagonally from one another where possible,
providing more space for growth, and a more complete barrier to wind and noise (Agriculture and
Agri-Food Canada, 2010). Within each flanking row, a pair of similarly sized species will be planted in
alternating fashion. These alternating rows effectively double the diversity of the planting, and
through increased diversity the food source becomes less vulnerable to disease (Agriculture and
Agri-Food Canada, 2010).
The plants present in each row of the proposed shelterbelt have been chosen based on the
benefits they provide to pollinators; as well as their compatibility with the conditions of the
meadow, with the climate of Lindsay, and with each other (Chan, 2012). As previously mentioned,
the central row will consist of white spruce, and flanking these, rows of alternating red and sugar
maple saplings. In the remaining rows, changes to the soil conditions will be made to benefit the
species planted, replacing the existing sandy clay loam A-horizon with a loam or clay loam. This more
fertile, water-retaining topsoil will aid in the establishment of the productive, moisture loving plants
of the outer rows. Following the change in topsoil, rows of hawthorn and black cherry trees will be
planted, followed by rows of blueberry and black raspberry bushes, and finally, outermost rows of
blue vervain and bee balm (Chan, 2012). In the outlined conditions, these species are well suited to
survive in Lindsay’s hardiness zone of 5a.
Spacing among these rows should be according to the needs of the various plants. Outward
from the spruces, rows will be four metres, four metres, two metres, and then one metre away.
Within each row, and ordered from the centre outwards, spacing will be three metres, five metres,
three metres, one metre, and finally 50 centimetres. With this spacing, the plants will be healthy and
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 22
productive, and in the long term will grow to provide maximum cover to the meadow (Agriculture
and Agri-Food Canada, 2010).
Additional Foraging
As previously noted, the interior area of the drill shed meadow is approximately 7,400
square metres, and is home to primarily grassland, but also woodland flora and fauna. To reinforce
the mixed conditions of the meadow, scattered wildflowers and flowering plants should be planted
within the interior of the plot. Native species are more appropriate in this role, given their tendency
not to overspread and become weedy, and once established require no maintenance to thrive given
their evolutionary ties to local pollinators (Hatfield, Hoffman Black, Jepsen, Mader, & Shepherd,
2012). Bombus species are known to have a colour preference in plants; preferring blue, purple and
yellow flowers; and essentially will not forage red flowers as they are blind to the colour (Hatfield,
Hoffman Black, Jepsen, Mader, & Shepherd, 2012). B. affinis has also developed a special technique
of collecting nectar, in which workers pierce the corollas of flowers with their short tongues, making
both long and short stemmed flowers accessible to forage (Hatfield, Hoffman Black, Jepsen, Mader,
& Shepherd, 2012).
The proposed plants are perennials, as they return each year, are hardier and tend to
contain higher quantities of nectar than annuals (Hatfield, Hoffman Black, Jepsen, Mader, &
Shepherd, 2012). Given their location in the centre of the field, they must be able to tolerate full sun,
and are therefore mostly shade intolerant. Effort has also been made to select plants that bloom at
different times throughout the active season of B. affinis, in order to provide further food resources
(COSEWIC, 2010).
Keeping with the aforementioned themes, as well as the soil and climate conditions of
Lindsay, the group has selected six herbaceous species that would be well suited to planting in the
meadow. In no particular order; lavender hyssop, New England aster, blue vervain, and fireweed
should be planted where vegetation is sparse. In an exception to the rule of planting only native
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 23
species, the group also recommends the planting of both sweet clovers and wild chives, as they are
non-invasive and have a blooming period beginning in April and May, earlier than the suitable native
species (Chan, 2012). These herbaceous perennials will enhance the variety and volume of available
flowering plants, and co-exist with the wild carrot, common milkweed, and goldenrod that are
already established in the drill shed meadow (Baker, Hennink, Huitema, Jackson, & Wilson, 2016).
Artificial Nesting
The next step to attract and sustain B. affinis in the drill shed meadow involves the creation
of adequate artificial shelter to nest in. Statistically, over 90% of B. affinis in Canada and the United
States have been found to nest underground, largely in abandoned rodent burrows (COSEWIC,
2010). Numerous studies conducted throughout the United Kingdom, New Zealand, and North
America examining the viability of artificial nests have found that while Bombus species will use
artificial nests, they are not consistently inhabited. In accordance with the preference of most
Bombus species to nest below ground, nests built above ground were very rarely occupied, while
underground nests were occupied up to 60% of the time (Dicks, Showler, & Sutherland, 2016).
To best accommodate the nesting habits of B. affinis, artificial nests placed in the drill shed
meadow should be built underground, and structured similarly to rodent burrows. If assembled at a
sufficient depth and with sufficiently limited access, these nests could provide security from most
predators, being only accessible by B. affinis and similarly sized insects (Lye, 2009). To most
effectively provide attractive nesting opportunities for B. affinis, the group recommends the
construction of 10 to 15 subterranean artificial nests. For best results, these nests should follow the
complex domicile model presented in Figure 3.6 of the report Nesting Ecology, Management and
Population Genetics of Bumblebees: An Integrated Approach to the Conservation of an Endangered
Pollinator Taxon, as shown in Figure 8 (Lye, 2009).

Figure 8 – Complex subterranean domicile nest design (Lye, 2009)
In the aforementioned report, six designs of artificial nest were tested on agricultural land in
Scotland, with the complex subterranean shown in Figure 8 being not only the most commonly
occupied by Bombus species, but also the least occupied by other competitors (Lye, 2009). The
complex subterranean domicile, compared to many mass-produced bee boxes, is very cost-effective,
and can be assembled as needed. The casing itself consists of two pairs of plastic flowerpots joined
at the mouths, 16 and 14 centimetres in diameter respectively. The larger pots are sealed to be
waterproof, and contain the smaller, perforated set of pots. Small holes are drilled in the bottom
side of the nest, acting as a drainage system for feces and moisture, and then covered with thin
nylon mesh to prevent insects from entering. The casing is buried 10 to 30 centimetres deep, and
joined to the surface by a pair of two centimeter PVC tubes, one being used as the entrance, and the
other meshed-over to act as a ventilation chimney (Lye, 2009). Within the inner chamber, a thin
layer of chicken wire provides structure, and is covered in wool and natural fibres such as mosses to
imitate the bedding inside a rodent burrow (Lye, 2009).
Once nests have been installed, the final measure to be taken involves nearly completely
covering both pipe entrances with stones or tiles, to keep out intruders. The abundant limestone
slates already present in the meadow would fill this role effectively, and avoid the need for
additional materials. To maximise chance of occupation, nests will be distributed throughout the
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 25
central regions of the meadow. Recommended spacing is at least three metres between domiciles,
so to provide ample space, five metres of space will be given (Lye, 2009). An example of distribution
of these nests can be seen in Figure 9.
Figure 9 – Shelterbelt with potential locations for nesting & signage (Baker, Hennink, Huitema, Jackson, & Wilson, 2016)
Signage for Conservation
The final step in the installation of the proposed shelterbelt will be to create, post, and
maintain adequate signage informing the public of the importance of the habitat created within the
drill shed meadow. Examples of locations where signage should be placed can be found in Figure 9.
B. affinis is considered a critically endangered species, and as the first federally listed bee in North
America B. affinis and their habitat are considered protected (Government of Ontario, 2015; Wildlife
Preservation Canada, 2016). As such, habitat designed specifically for this endangered species should
also be protected. Signage will be placed along the walkways surrounding the shelterbelt, providing
PROPOSAL: BOMBUS AFFINIS SHELTERBELT IN THE DRILL SHED MEADOW 26
the public with basic information on B. affinis, descriptive pictures, and caution against disturbing
the artificial habitat. The walking paths surrounding the drill shed meadow have been heavily
trafficked by humans and pets, so providing proper information to these individuals will help prevent
any unnecessary entrance or damage to the habitat (Baker, Hennink, Huitema, Jackson, & Wilson,
2016).

ConclusionInitial research gathered concluded that the drill shed meadow, with some modification,
could potentially provide an excellent habitat for Bombus affinis. Local climate and vegetation were
all identified to be suitable, and survey of local soil conditions provided insight into what vegetation
the meadow could support (Government of Canada, 2010). Problematic factors such as drilling
activity, prevailing winds, and human presence in the region were identified, and then accounted for
in the design stage (Baker, Hennink, Huitema, Jackson, & Wilson, 2016).
Extensive research and discussion leads the group to propose the enclosed shelterbelt
design, as well as several additional changes. A major planting of white spruce, maples, and various
other flowering plants along the north and east boundaries of the meadow is recommended,
including the replacement of topsoil in some rows. This planting would serve primarily to provide
food to pollinators such as B. affinis, incorporating eight excellent food species (Chan, 2012). In its
secondary function, the shelterbelt will serve to deter human traffic through the region, supported
by the placement of informative signage. The proposed planting would further act as a windbreak,
dispersing both winds and noise from the western drilling lot (Baker, Hennink, Huitema, Jackson, &
Wilson, 2016; Government of Canada, 2010).
In further steps to attract B. affinis to the region, the group proposes several other minor
additions to the interior of the meadow. Outside of the shade of the shelterbelt, further food species
should be planted, providing an abundance of flowering plants. Finally, artificial nests should be
constructed and buried throughout the meadow, based on the research of Gillian Clare Lye (Lye,
2009). These nests have proven success in supporting Bombus species, and provide cost-effective
and safe habitat by incorporating the limestone debris already found on the site.
In combination, the improvements proposed in this report satisfy all the needs of B. affinis,
and would transform the drill shed meadow into the most suitable habitat possible.
