I n theIr 1996 book , t he F orgotten P ollInators , Buchmann andNabhan estimated that animal pollinators are needed for the reproduction
of 90% of owering plants and one third of human food crops. Each of usdepends on these industrious pollinators in a practical way to provide us with the wide range of foods we eat. In addition, pollinators are part of theintricate web that supports the biological diversity in natural ecosystems
that helps sustain our quality of life.
Abundant and healthy populations of pollinators can improve fruit setand quality, and increase fruit size. In farming situations this increases
production per acre. In the wild, biodiversity increases and wildlife foodsources increase.
Persimmons, peaches, onions and cantaloupes are some of the cropsraised in the Southwest Plateau and Plains Dry Steppe that rely onhoney bees and native bees for pollination. Domestic honey bees pollinateapproximately $10 billion worth of crops in the U.S. each year.
Unfortunately, the numbers of both native pollinators and domesticated bee populations are declining. They are threatened by habitat loss,disease, and the excessive and inappropriate use of pesticides. The loss of commercial bees to Colony Collapse Disorder (CCD) has highlighted howsevere the issues of proper hive management are to reduce stresses caused
by disease, pesticide use, insuf cient nutrition, and transportation practices.Currently, the pollination services that the commercial beekeeping industry provides are receiving much needed research and conservation resources.The efforts to understand the threats to commercial bees should help usunderstand other pollinators and their roles in the environment as well.
It is imperative that we take immediate steps to help pollinator populations thrive. The beauty of the situation is that by supporting pollinators needfor habitat, we support our own needs for food and support diversity in thenatural world.
Thank you for taking time to consult this guide. By adding plants to your landscape that provide food and shelter for pollinators throughout theiractive seasons and by adopting pollinator friendly landscape practices, youcan make a difference to both the pollinators and the people that rely on them.

Southwest Plateau and Plains Dry Steppe and Shrub Province
t hIs regIonal guIde Is just one
in a series of plant selection toolsdesigned to provide informationon how individuals can in uence
pollinator populations throughchoices they make when they farma plot of ground, manage large
tracts of public land, or plant agarden. Each of us can have a
positive impact by providing theessential habitat requirements for
pollinators including food, water,
shelter, and enough space to allow pollinators to raise their young.
Pollinators travel through the landscape without regard to property ownership or state boundaries. Weve chosen to useR.G. Baileys classi cation system to identify the geographic focusof this guide and to underscore
the connections between climateand vegetation types that affect
the diversity of pollinators in theenvironment.
Baileys Ecoregions of the UnitedStates, developed by the UnitedStates Forest Service, is a systemcreated as a management tooland is used to predict responses
to land management practices
throughout large areas. This guide
addresses pollinator-friendly landmanagement practices in what isknown as the Southwest Plateauand Plains Dry Steppe and ShrubProvince.
This 160,900 square mile provinceis a region primarily varied byirregular plains and tablelands withareas of at to rolling plains, hills,and plateaus dissected by canyons
with moderate relief. Elevations at the Gulf Coastal Plain range fromsea level to 4,000 feet and rise to6,500 feet near the Rocky MountainPiedmont. The semiarid climate ischaracterized by short and mild
winters and long and hot summers with an extensive frost-free season. Annual temperatures average from60 to 70F. Annual rainfall rangesfrom 30 inches in the east to10 to 15inches in the west, and is exceeded
by up to 80 inches of annualevaporation.
This province is characterized by a unique collection of aridgrasslands. On eastern NewMexico and Northwest Texas plains, buffalo grass and blue grama areinterspersed with mesquite. Oak,
juniper and needlegrass dominate
plateaus, where trees grow low andin open stands (unless on steeprocky slopes) due to low rainfall.Ceniza shrub is prevalent along thedescent to the Rio Grande wherea forest of mesquite-grassland,including subtropical semiarid
vegetation such as the endangeredsabal palm, inhabits the delta. TheGulf Coast supports areas of liveoak forest.
Long before there were homesand farms in this area, the original,natural vegetation providedcontinuous cover and adjacentfeeding opportunities for wildlife,including pollinators. In choosing
plants, aim to create habitat for pollinators that allow adequate foodshelter, and water sources. Most
pollinators have very small homeranges. You can make a difference
by understanding the vegetation patterns of the farm, forest, orneighbors yard adjacent to youand by making planting choices
that support the pollinators needfor food and shelter as they move
through the landscape.

Who are thepollinators?
BeesBees are well documented pollinators in the natural andagricultural systems of theSouthwest Plateau and Plains DrySteppe. A wide range of cropsincluding persimmons, peaches,onions and cantaloupes are just afew plants that bene t from bee
pollinators.Most of us are familiar with thecolonies of honey bees that have
been the workhorses of agricultural pollination for years in the UnitedStates. They were imported fromEurope almost 400 years ago.
There are nearly 4000 species of native ground and twig nesting beesin the U.S. Some form colonies
while others live and work a solitary life. Native bees currently pollinatemany crops and can be encouraged
to do more to support agriculturalendeavors if their needs for nestinghabitat are met and if suitablesources of nectar, pollen, and waterare provided. Bees have tongues of
varying lengths that help determine which owers they can obtain nectarand pollen from.
The bumble bee ( Bombusspp.) formssmall colonies, usually underground.They are generalists, feeding on a wide range of plant material fromFebruary to November and areimportant pollinators of tomatoes.The sweat bee (family Halictidae)nests underground. Various species
are solitary while others form loosecolonies.
Solitary bees include carpenter bees( Xylocopaspp.), which nest in wood;digger, or polyester bees ( Colletes spp.), which nest underground;
leafcutter bees ( Megachilespp.), which prefer dead trees or branchesfor their nest sites; and mason bees(Osmia spp.), which utilize cavities that they nd in stems and dead wood. Cactus bees ( Diadasia spp.)are also solitary ground nesters.
Butter iesGardeners have been attracting butter ies to their gardens for some time. These insects tend to be eye-catching, as are the owers thatattract them. Position owering
plants where they have full sun andare protected from the wind. Also,
you will need to provide open areas(e.g. bare earth, large stones) where butter ies may bask, and moist soilfrom which they may get neededminerals. By providing a safe place to eat and nest, gardeners can alsosupport the pollination role that
butter ies play in the landscape. Itmight mean accepting slight damage to the plants, known as host plants, that provide food for the larval stageof the butter y.
A diverse group of butter iesare present in garden areas and
woodland edges that provide brightowers, water sources, and speci c
host plants. Numerous trees, shrubs,and herbaceous plants support
butter y populations.

Lepidoptera. Some of the species in the Southwest Plateau and Dry
Steppe are Ruddy Daggerwing,Isabellas Heliconian, AmericanSnout, Klugs Clearwing, EladaCheckerspot, and PipevineSwallowtail butter ies. Theyusually look for owers that providea good landing platform.
Wet mud areas provide butter ies with both the moisture andminerals they need to stay healthy.Butter ies eat rotten fruit and evendung, so dont clean up all themesses in your garden!
MothsMoths are most easily distinguishedfrom butter ies by their antennae.Butter y antennae are simple with aswelling at the end. Moth antennaediffer from simple to featherlike,
but never have a swelling at the
tip. In addition, butter ies typicallyare active during the day; moths atnight. Butter y bodies are not veryhairy, while moth bodies are quitehairy and more stout.
Moths, generally less colorful than butter ies, also play a rolein pollination. They are attracted
to owers that are strongly sweetsmelling, open in late afternoon ornight, and are typically white or
pale colored.
BeetlesOver 30,000 species of beetlesare found in the United Statesand many of them can be foundon ower heads. Gardeners have
yet to intentionally draw beetles
to their gardens, possibly because beetle watching isnt as inspiring
as butter y or bird watching. Yet beetles do play a role in pollination.Some have a bad reputation because they can leave a mess behind,damaging plant parts that they eat.Beetles are not as ef cient as some pollinators. They wander betweendifferent species, often dropping
pollen as they go.
Beetle pollinated plants tend to be large, strong scented owers with their sexual organs exposed. Theyare known to pollinate Magnolia,sweetshrub ( Calycanthus), paw
paws, and yellow pond lilies.
FliesIt may be hard to imagine why one would want to attract ies to thegarden. However, like beetles, thenumber of y species and the fact
that ies are generalist pollinators(visit many species of plants),should encourage us all to leave
those ies alone and let them do their job as pollinators.
Recent research indicates that ies primarily pollinate small owers that bloom under shade and inseasonally moist habitats. TheNational Research Councils Status of Pollinators in North Americastudystates that ies are economicallyimportant as pollinators for a rangeof annual and bulbous ornamental
owers.
Plants pollinated by the yinclude the American pawpaw( Asimina triloba), dead horse arum( Helicodiceros muscivorus), skunk
cabbage ( Symplocarpus foetidus),goldenrod ( Solidagospp.), and
members of the carrot family likeQueen Annes lace ( Daucus carota).
BirdsHummingbirds are the primary birds which play a role in pollinationin North America. Their long beaksand tongues draw nectar from
tubular owers. Pollen is carriedon both the beaks and feathersof different hummingbirds. Theregions closer to the tropics, with
warmer climates, boast the largestnumber of hummingbird speciesand the greatest number of native
plants to support the birds need forfood. White-winged doves ( Zenaida asiatica) are also pollinators of thesaguaro cactus ( Carnegeia gigantea) in
the south central United States.
Bright colored tubular owers
attract hummingbirds to gardens throughout the United States.Hummingbirds can see the colorred; bees cannot. Nectar plantsgrowing in the Southern RockyMountain Steppe, including
reweed and elephant head, attract boad-tailed hummingbirds.
BatsIn the Southwest Plateau and PlainsDry Steppe, Sanborns long-nosed bats play an important role in the pollination of agave, organ pipe andsaguaro cacti. The long-nosed batshead shape and long tongue allowsit to delve into ower blossoms andextract both pollen and nectar.

n ot all PollInators are foundin each North American province,and some are more important
in different parts of the UnitedStates. Use this page as a resource to understand the plants and pollinators where you live.
Plants can be grouped together based on the similar characteristicsof their owers. These oralcharacteristics can be useful to
predict the type of pollinationmethod or animal that is mosteffective for that group of plants.This association between oralcharacteristics and pollinationmethod is called a pollinationsyndrome.
The interactions of animal pollinators and plants havein uenced the evolution of bothgroups of organisms. A mutualisticrelationship between the pollinatorand the plant species helps the
pollinator nd necessary pollen andnectar sources and helps the plantreproduce by ensuring that pollen iscarried from one ower to another.

Selecting Plants for Pollinators12
W hether you are a Farmer of many acres, land manager of a
large tract of land, or a gardener with a small lot, you can increase the number of pollinators in yourarea by making conscious choices toinclude plants that provide essentialhabitat for bees, butter ies, moths,
beetles, hummingbirds and other pollinators.
Food:Flowers provide nectar (high insugar and necessary amino acids)and pollen (high in protein) to
pollinators.Fermenting fallen fruits also providefood for bees, beetles and butter ies.Speci c plants, known as host plants, are eaten by the larvae of pollinators such as butter ies. Plant in groups to increase pollination ef ciency. If a pollinatorcan visit the same type of owerover and over, it doesnt have torelearn how to enter the owerand can transfer pollen to the samespecies, instead of squandering the
pollen on unreceptive owers. Plant with bloom season in mind, providing food from early spring to late fall. (see Bloom Periods pp.16-17) Plant a diversity of plants tosupport a variety of pollinators.Flowers of different color,fragrance, and season of bloomon plants of different heights willattract different pollinator speciesand provide pollen and nectar
throughout the seasons. Many herbs and annuals, although
not native, are very good for pollinators. Mint, oregano, garlic,chives, parsley and lavender are
just a few herbs that can be planted.Old fashioned zinnias, cosmos, andsingle sun owers support bees and
butter ies. Recognize weeds that might be agood source of food. For example,dandelions provide nectar in theearly spring before other owersopen. Plantain is alternate host for
the Baltimore Checkerspot.
Learn and utilize Integrated PestManagement (IPM) practices toaddress pest concerns. Minimize oreliminate the use of pesticides.
Shelter:Pollinators need protection fromsevere weather and from predatorsas well as sites for nesting androosting.
Incorporate different canopy layers in the landscape by planting trees, shrubs, and different-sized perennial plants. Leave dead snags for nesting sitesof bees, and other dead plants and
leaf litter for shelter. Build bee boxes to encouragesolitary, non-aggressive bees to nest
on your property. Leave some areas of soil uncovered to provide ground nesting insectseasy access to underground tunnels.
Group plantings so that pollinatorscan move safely through the
landscape protected from predators. Include plants that are needed
by butter ies during their larvaldevelopment.
Water: A clean, reliable source of water isessential to pollinators.
Natural and human-made waterfeatures such as running water, pools, ponds, and small containersof water provide drinking and
bathing opportunities for pollinators. Ensure the water sources havea shallow or sloping side so the
pollinators can easily approach the water without drowning.
Your current landscape probablyincludes many of these elements.Observe wildlife activity in your farm
elds, woodlands, and gardens todetermine what actions you can take
to encourage other pollinators to feedand nest. Evaluate the placement of individual plants and water sourcesand use your knowledge of speci c
pollinator needs to guide your choiceand placement of additional plantsand other habitat elements. Minorchanges by many individuals can
positively impact the pollinator populations in your area. Watchfor - and enjoy - the changes in your landscape!
CAUTION: Remember that pesticides are largely toxic to pollinators. Extreme caution is warranted if you choose to useany pesticide. Strategically apply
pesticides only for problematic target species.

Farms
Persimmons, peaches, onions andcantaloupes are a few of the foodcrops in the Southwest Plateauand Plains Dry Steppe and ShrubProvince that will bene t fromstrong native bee populations
that boost pollination ef ciency.Incorporate different plants throughout the farm that providefood for native populations when
targeted crops are not in ower.
Farmers have many opportunities
to incorporate pollinator-friendly land management practices on their land which will bene t the farmerin achieving his or her productiongoals:
Manage the use of pesticides to reduce the impact on native pollinators. Spray when bees arentactive (just after dawn) and choose
targeted ingredients.
Carefully consider the use of
herbicides. Perhaps the targeted weeds can provide needed food for pollinators. Minimize tillage to protect groundnesting pollinators.
Ensure water sources are scattered throughout the landscape. Choose a variety of native plants toact as windbreaks, riparian buffers,and eld borders throughout thefarm.
Plant unused areas of the farm with temporary cover crops that
can provide food or with a varietyof trees, shrubs, and owers that
provide both food and shelter for pollinators. Check with your local NaturalResources Conservation Service(NRCS) of ce to see what technicaland nancial support might beavailable to assist you in your effort to
provide nectar, pollen, and larval food
sources for pollinators on your farm.

Public Lands
Public lands are maintained forspeci c reasons ranging from highimpact recreation to conservation.In the Southwest Plateau andPlains Dry Steppe grasses andshrubs have been cut to allow forhomes, businesses and farms. Lessdisturbed natural areas can beaugmented with plantings of native
plant species. Existing plantingsaround buildings and parking areasshould be evaluated to determineif pollinator-friendly plants can
be substituted or added to attract
and support pollinators. Public land managers have a uniqueopportunity to use their plantingsas an education tool to help othersunderstand the importance of pollinators in the environment through signs, brochures, and public programs.
In an effort to increase populationsof pollinators the land manager can:
Inventory and becomeknowledgeable of local pollinators.
Provide connectivity between vegetation areas by creatingcorridors of perennials, shrubs, and
trees that provide pollinators shelterand food as they move through the
landscape. Maintain a minimum of lawn areas that support recreational needs. Restrict the use of pesticides andherbicides.
Provide water sources in largeopen areas.
Maintain natural meadows andopenings that provide habitats forsun-loving wild owers and grasses.
Remove invasive species andencroaching shrubs and trees.

Gardeners have a wide array of plants to use in their gardens.
Native plants, plants introducedfrom years of plant explorationfrom around the world, and plantsdeveloped by professional andamateur breeders can be found ingarden centers, in catalogs, andon web-sites. Use your knowledgeof pollinator needs to guide yourchoices.
Choose a variety of plants that
will provide nectar and pollen throughout the growing season. Resist the urge to have a totallymanicured lawn and garden. Leave
bare ground for ground nesting bees. Leave areas of dead wood and leaf litter for other insects. Strive to eliminate the use of all pesticides. Find local resources to help you
in your efforts. Contact your localcounty extension agent or native plant society. Visit your regional botanic gardens and arboreta.
The scale of your plantings will vary but it is important to remember
that you are trying to provideconnectivity to the landscapeadjacent to your property. Dont
just look within your property boundaries. If your neighbors property provides an essentialelement, such as water, which can
be utilized by pollinators visiting your land, you may be able todevote more space to habitat
elements that are missing nearby.It is best to use native plants whichhave evolved to support the needsof speci c native pollinators. Some
pollinators, however, are generalistsand visit many different plants, bothnative and non-native. Be sure thatany non-native plants you choose
to use are not invasive. Remember that specialized cultivars sometimes
arent used by pollinators. Flowers that have been drastically altered,such as those that are double ora completely different color than
the wild species, often prevent pollinators from nding and feedingon the owers. In addition, somealtered plants dont contain the samenectar and pollen resources thatattract pollinators to the wild types.
CAUTION: Take time to evaluate the source of your plant material. You want to ensure you get plants that are healthy and correctlyidenti ed. Your local native plantsociety can help you make informeddecisions when searching for plants.

PRAIRIE
Bumble Bees:Abandoned mouse nests, other rodent burrows, upside down ower pots, under boards,and other human-made cavities. Colonies are founded by a queen in the spring anddont die out in the fall. New queens mate then and overwinter in a sort of hibernation.Bumble bees are usually active during the morning hours and forage at coldertemperatures than honey bees, even ying in light rain.
Large carpenter bees:Soft dead wood, poplar, cottonwood or willow trunks and limbs, structural timbersincluding redwood. Depending on the species, there may be one or two brood cycles peryear. These bees can be active all day even in the hottest weather.
Digger bees:Sandy soil, compacted soils, bank sides. Anthophorid bees (now in the Apidae) are usuallyactive in the morning hours, but can be seen at other times.
Small carpenter bees:Pithy stems including roses and blackberry canes. These bees are more active in themorning but can be found at other times.
Squash and Gourd bees:Sandy soil, may nest in gardens (where pumpkins, squash and gourds are grown) orpathways. These bees are early risers and can be found in pumpkin patches before dawn.Males often sleep in the wilted owers.
Leafcutter bees:
Pre-existing circular tunnels of various diameters in dead but sound wood created byemerging beetles, some nest in the ground. Leave dead limbs and trees to support not just pollinators but other wildlife. Leafcutter bees can be seen foraging throughout theday even in hot weather.
Mason bees:Pre-existing tunnels, various diameters in dead wood made by emerging beetles, orhuman-made nesting substrates, drilled wood boards, paper soda straws inserted intocans attached to buildings. Mason bees are generally more active in the morning hours.
Sweat bees:Bare ground, compacted soil, sunny areas not covered by vegetation. Like most bees,sweat bees forage for pollen earlier in the morning and then for nectar later.
Plasterer or cellophane bees:Bare ground, banks or cliffs. Colletid bees can be active in the morning or later in the day.
Yellow-faced bees:In dead stems. These bees are more active during morning hours.
Andrenid bees:Sunny, bare ground, sand soil, under leaf litter or in soil in banksides and cliffs. Thesegenerally spring-active bees are most commonly seen on owers during the morningwhen pollen and nectar resources are abundant.

Become familiar with pollinatorsin your landscape.
n Watch for activity throughout the day and the seasons.n Keep a simple notebook of when and what comes to your garden.
NOTE: It is not necessary to identify each species when you rstget started. Simply note if it is a bee that likes the yellow ower that
blooms in the fall.n Consult a local eld guide or web site when you are ready to
learn more details.
Add native plants to attract morenative pollinators.
n List the plants you currently have in your landscape.n Determine when you need additional owers to provide nectar and
pollen throughout the growing season.n Add plants that provide additional seasons of bloom, create variable
heights for shelter, and attract the types of pollinators you want.n Dont forget to include host plants that provide food and shelter for
larval development.n Contact your local native plant society or extension agent for more
help.
Use pollinator friendly landscapepractices to support thepollinators you attract.
n Use Integrated Pest Management Practices to address pest concerns.n Tolerate a little mess leave dead snags and leaf litter, keep areas bare
for ground nesting insects, and leave some weeds that provide food for pollinators.
n Provide safe access to clean water.
