Three Bumble Bees of Idaho

Bees are vital to Idaho's ecosystems and agricultural economy, serving as key pollinators for crops, wild plants, and native vegetation. The Treasure Valley, with its fertile soils and ideal climate, is home to both wild and managed bee populations that play an essential role in maintaining biodiversity and ensuring agricultural productivity. From honeybees to native species, these pollinators are crucial for supporting crops such as fruits, vegetables, and seeds, making them indispensable, to the region's farmers and gardeners. Protecting and encouraging healthy bee populations is vital not only for Idaho’s agricultural success but also for preserving its diverse natural habitats.

Idaho's landscapes host a variety of bee species. Three of the over twenty species of bumble bees that have been observed in various regions of Idaho on a myriad of plants are summarized below.

Red-Belted Bumble Bee
(Bombus rufocinctus)
This beauty thrives in higher elevations, such as the Northern Rockies and Idaho Batholith, foraging on plants like lupines, sweet clover, and knapweed. It is a significant pollinator in meadows, forests, and shrublands.
 


Hunt’s Bumble Bee
 
(
Bombus huntii)
The Hunt’s Bumble Bee is highly adaptable, thriving in diverse habitats such as riparian zones and shrublands, often visiting flowers like teasel and lupine.
 




Morrison Bumble Bee 
(
Bombus morrisoni)
This Bumble Bee is found in grasslands, sagebrush steppes, and even urban parks, where it pollinates a wide range of flowering plants including milkweed, thistle and bee balm. The Morrison Bumble Bee population has been in decline in recent years and the monitoring of it is of particular interest. 



Supporting Idaho’s bee populations requires community action. Planting native flowers, creating
pollinator gardens, reducing pesticide use, and preserving wild habitats are essential steps to help bees thrive. Small efforts, like planting diverse flowers in urban areas or leaving natural spaces untouched, can significantly impact the survival of these pollinators. By fostering environments that support healthy bee populations, we not only contribute to agricultural productivity but also sustain the natural beauty and biodiversity of Idaho. For more information on creating pollinator-friendly spaces, visit Creating Bee Habitat in Idaho or Planting a Bee Garden. Together, we can ensure that Idaho’s bees—and the ecosystems they support—thrive for generations to come.

I want a fruit...& maybe a nut tree - Now What?

 Selecting fruit trees to grow in your yard or orchard depends on several factors:  available space, height and width restrictions, soil type, exposure to good light and air circulation, preferred type of fruit, type of root-stock, and much more. 

The first step is to plan. 
·         The following factors should be considered as you plan: 
  • Climate zone
  • Soil type and pH
  • Location and surrounding landscaping
  • Drainage
  • Overhead restrictions (power lines, other trees, shading)
  • Width restrictions (fences, buildings property lines)
  • Underground restrictions (sewer/power/telephone lines, septic tanks or drain fields, layers of poor soil, wells)
  • Irrigation and fertilizing
  • Time needed for tree care
  • Pruning
  • Harvesting
  • Spraying
Selection of the trees is one of the most important steps. 
There are several great resources to help you select a tree for your yard.
The Pacific Northwest Handbooks publication EC 819, Growing Tree Fruits and Nuts in the Home Orchard  The Treasure Valley is Area II in this publication.
Other factors to consider are: 
  •          Choose a reliable nursery with appropriate stock selected for this area
  •          Choice of fruit
  •          Varieties of chosen fruit that grow best in this region 
  •          Dwarf or semi-dwarf root stock
  •          Bare root, ball and burlap (B&B), or containerized stock
  •         Need of a pollinator or self-pollinator,
  •          Blooming and harvest times
  •          Pests – insects, birds, or disease resistant
To maintain a strong tree or orchard, time must be given towards tree health.   There are numerous publications from Extension Services through the University of Idaho, Washington State University, and Oregon State University to assist you with your specific trees.


The following are important items to consider toward maintaining a vigorous home fruit tree:
  •          Training of tree branches
  •         Thinning and pruning
  •          Irrigation needs
  •          Fertilization needs
  •          Insect and disease control
  •          Weed 
  •          Rodent control
A backyard fruit tree or orchard is a wonderful addition to your landscaping.  Be sure to choose trees that are compatible to your region, soil, and property.  With the proper selection, you can enjoy fruit from your backyard trees for many years to come.
