Here are 6 important things you can do to help pollinators:
1. Provide Suitable Habitat
Gardens, backyard vegetable patch, community gardens, planter boxes, roof top agriculture all provide places for growing plants that are suitable for pollinators.
2. Encourage Wild spaces
Be the voice in your community to invest in green spaces with provision for lots of unmowed "wild" spaces.
Petition your council to plant roadside zones with bee friendly plants such as clover.
3. Plant Bee Friendly Flowers
Pollinating insects need pollen and nectar for food. Plant a variety of flowers with different floral shapes to encourage a diversity of pollinators.
Seeds of Diversity offers useful information on improving habitat for pollinators.

4. Grow Pollinator Friendly Plants
Wasps and flies are beneficial for gardeners and should be encouraged along with other pollinators. Predator insects such as parasitoid wasps kill caterpillars and can help reduce the need for chemical intervention. Encourage them by planting flowering species that attract them. Linda Gilkeson author of West Coast Gardening recommends plants with tiny, nectar-rich flowers in the garden: thymes, lovage, savory and other herbs, sweet alyssum, dill, cilantro, parsley, yarrow, candytuft, verbena, goldenrod
5. Create Artificial habitat (nest boxes) for beneficial biota
Native Bees: Many species are beneficial to gardeners and should be encouraged. Native bees such as mason bees are great pollinators and can be encouraged with nest boxes.
Bats: A little brown bat eats hundreds of moths, beetles and other flying insects daily. They are great for pest control and research shows mosquitoes form up to 1% of their diet. Bats are an important part of the urban ecosystem.
Build a bat house to encourage these small, insectivorous and very cute little brown bats.
6. Reduce Pesticides
All pollinators are sensitive to pesticides. The toxicity effect depends on the type of pesticide, the timing and dosage. If a chemical is necessary, (use only when the need arises) always choose the lowest toxicity, target the one pest and READ the LABEL directions carefully.
You can help protect all pollinators by eliminating the use of synthetic chemical pesticides. Simple solutions exist to remove unwanted plants and insects. Vinegar sprayed on weeds will kill without leaving a toxic residue. Detergent can be sprayed on aphids to reduce their numbers. Planting a variety of plants removes the "smorgasborg" effect for insects that prefer one species. Good pairing of plants often provides a repellent effect for some pests (eg marigolds have some repellent affect on nematodes). And there is a lot to be said for removing the pest manually without resorting to toxic chemicals.
