Example: In Europe, various species of solitary bees, such as mason bees and mining bees, are common. Understanding their nesting preferences (e.g., cavities in wood or bare ground) is crucial for creating suitable habitats. In North America, native bee species like bumble bees, leafcutter bees, and sweat bees require different types of flowering plants and nesting sites.

Choosing the Right Location

The location of your bee sanctuary significantly impacts its success. Consider the following factors when selecting a site:

Sunlight: Bees require plenty of sunlight for foraging and nesting. Choose a location that receives at least six hours of direct sunlight per day.
Water Source: Bees need access to fresh water. Provide a shallow dish or bird bath with pebbles for bees to land on and drink safely.
Shelter: Bees need protection from wind and rain. Plant shrubs, trees, or create windbreaks to provide shelter.
Proximity to Pesticides: Avoid locations near areas where pesticides are used. Pesticides are harmful to bees and can decimate populations.
Soil Type: Consider the soil type when selecting plants. Amend the soil as needed to ensure optimal growing conditions.
Accessibility: Make the sanctuary accessible for maintenance and educational purposes, if applicable.

Selecting Bee-Friendly Plants

Providing a diverse range of flowering plants that bloom throughout the growing season is essential for providing bees with a continuous food source. Choose native plants whenever possible, as they are best adapted to local conditions and provide the most nutritious pollen and nectar for native bees.

Key considerations when selecting bee-friendly plants:

Bloom Time: Select plants that bloom in succession throughout the spring, summer, and fall to provide a continuous food supply.
Flower Shape and Color: Bees are attracted to a variety of flower shapes and colors, including blue, purple, yellow, and white. Choose flowers with open or shallow shapes that are easy for bees to access.
Pollen and Nectar Richness: Select plants known for their high pollen and nectar content.
Native Plants: Prioritize native plants as they are best adapted to local conditions and provide the most nutritious food for native bees.
Avoid Cultivars with "Double" Flowers: These often have reduced pollen and nectar and can be difficult for bees to access.

Examples of bee-friendly plants by region:

North America: Milkweed (Asclepias spp.), Bee Balm (Monarda spp.), Sunflower (Helianthus spp.), Aster (Symphyotrichum spp.), Goldenrod (Solidago spp.).
Europe: Lavender (Lavandula spp.), Thyme (Thymus spp.), Borage (Borago officinalis), Clover (Trifolium spp.), Willow (Salix spp.).
Australia: Eucalyptus (Eucalyptus spp.), Bottlebrush (Callistemon spp.), Banksia (Banksia spp.), Grevillea (Grevillea spp.), Tea Tree (Melaleuca spp.).
Asia: Honeysuckle (Lonicera spp.), Buddleja (Buddleja davidii), Salvia (Salvia spp.), Cosmos (Cosmos bipinnatus), Zinnia (Zinnia elegans).
Africa: Aloes (Aloe spp.), Gazania (Gazania spp.), Leonotis (Leonotis leonurus), Bulbine (Bulbine frutescens), Cape Honeysuckle (Tecoma capensis).

Creating Nesting Sites

Bees require suitable nesting sites to reproduce and thrive. Different bee species have different nesting preferences. Providing a variety of nesting options will attract a wider range of bees to your sanctuary.

Types of bee nesting sites:

Ground-Nesting Bees: Many bee species, such as mining bees and digger bees, nest in the ground. Provide areas of bare, well-drained soil for these bees to dig their nests.
Cavity-Nesting Bees: Mason bees, leafcutter bees, and other cavity-nesting bees nest in pre-existing cavities, such as hollow stems, beetle tunnels, or bee hotels.
Bee Hotels: Bee hotels are artificial structures that provide a variety of nesting cavities for cavity-nesting bees. They can be made from wood, bamboo, or other natural materials.
Natural Materials: Leave standing dead trees or shrubs in your sanctuary to provide nesting sites for wood-nesting bees.

Building a Bee Hotel

Bee hotels are a popular and effective way to provide nesting sites for cavity-nesting bees. Here's how to build a simple bee hotel:

Gather Materials: You'll need a wooden box or frame, bamboo canes, hollow stems, drilled wood blocks, and wire mesh.
Prepare Nesting Cavities: Cut bamboo canes and hollow stems to various lengths (6-12 inches). Drill holes of different diameters (3-10 mm) into wood blocks. Make sure the holes are smooth and free of splinters.
Assemble the Bee Hotel: Pack the wooden box or frame with the prepared nesting cavities. Secure the bamboo canes and hollow stems with wire mesh to prevent them from falling out.
Install the Bee Hotel: Place the bee hotel in a sunny, sheltered location, facing south or east. Mount it on a wall, fence, or post, or hang it from a tree branch.

Providing Water Sources

Bees need access to fresh water for drinking and cooling their nests. Provide a shallow dish or bird bath filled with water and pebbles or marbles for bees to land on and drink safely. Change the water regularly to prevent mosquito breeding.
