Operation Trees for Bees: Plant Trees This Fall to Stem Climate Change & Pollinator Decline

By Phyllis Stiles, Bee City USA Founder & Pollinator Champion, Xerces Society
 
Most bees and other pollinator species are under stress, and while we wish could prescribe them some Prozac, the better action would be reducing as many of their stressors as possible. According to a United Nations study released in 2016, stressors include: fragmented habitat, poor nutrition, pesticides, diseases, parasites, and climate change, which are interacting to put 40% of insect pollinators at risk of extinction.
Pollinators Need Trees!
What if I told you just by planting a tree in an urban or suburban area, you could help lots of species of pollinators and birds, filter stormwater runoff before it pollutes and floods streams, reduce the urban heat island effect, and mitigate climate change? This is actually a case of too good not to be true! Almost all bees, butterflies, moths, wasps, flies, beetles, birds and bat pollinators would benefit tremendously from more native and/or blooming trees—veritable meadows in the sky. America’s nearly 3600 species of native bees rely on pollen from flowers as their primary source of protein and nectar for their carbohydrates. About more than 25% of bee species specialize on specific plants families for their pollen source, many of them native trees. Many butterflies and moths lay their eggs in native trees, where their caterpillars feast on the leaves. According to Dr. Doug Tallamy, author of Bringing Nature Home, native oaks (Quercus spp.) support 534 species of butterflies and moths, black cherries (Prunus spp.)–456, and willows (Salix spp.)–455. Many pollinator species nest or overwinter in leaf litter from trees, or in dead wood in small tunnels made by beetles and other critters.
Our Planet Needs Trees!
A recent study by the Intergovernmental Panel on Climate Change (IPCC) showed that forest restoration offers one of the best climate cooling solutions available today. You can read the report here.
 
For substantial impact, researchers found we would need to plant at least 1 trillion trees as soon as possible to allow them to begin sequestering carbon and restore forest ecosystems. Through the miracle of photosynthesis, healthy trees take carbon dioxide out of the atmosphere and store it in their leaves, trunks, branches and roots until they die.
 
While the IPCC study prioritized restoring forests, its central finding of the power of trees to store carbon and cool the planet serves as a good recommendation for urban areas as well. Equally important, those same trees offer hope for reversing some pollinator declines.
What Are You Waiting For? Get Buzzy!
 
Step 1
Gather a group of stakeholders who care about both pollinators and climate change to brainstorm what it would take to get lots of trees (preferably native or fruit trees) in the ground this fall and spring. Consider inviting your local Bee City USA or Bee Campus USA committee, tree nurseries and retailers, Audubon Society, Sierra Club, tree board, native plant society, beautification committees, civic groups and Master Gardeners. There are 3 goals for this planning meeting: a) Set a time and place for a public meeting; b) Brainstorm a list of local native tree suppliers; and, c) Determine who will quickly survey those suppliers to develop a recommended list of native trees including whether they are available this fall or next spring.

CAUTION FOR FALL TREE PLANTING
Dug, balled and burlapped trees are considered fall transplant hazards, including many natives. Trees grown in containers should be safer as long as they are planted well, with roots spread out and in good contact with the native soil. Read more here.

Step 2
Identify the meeting facilitator and promote the meetinginvite your email lists and run a guest editorial or ad in local media for a few weeks to announce the public meeting to recruit tree planters.
Step 3
At the public meeting, share the recommended species list and suppliers, explain the goals for “Operation Trees for Bees,” and ask how many trees they think their community could plant within 12 months. With that target in mind, ask who will buy the trees, who will plant them and where? Identify stream banks that could use more trees and shrubs for stabilization and, in turn, serve as welcoming habitat corridors for pollinators. (Friendly competition among organizations or neighborhoods can be a good motivator!) Realizing that trees must be tended if they are to grow up and sequester lots of carbon, perhaps each stakeholder group could commit to a certain number of trees they feel is realistic for them. Trees could be bought in bulk and resold, or individuals could buy their own tree from a retailer.  To sustain enthusiasm and recognize those who are planting trees, ask someone to set up a website or Facebook page to track progress. It would be great to have a very public “thermometer sign” somewhere in town to track progress as well. An artist could have lots of fun with the sign!
Step 4
Implement the plan and host a celebration at the end of the year for all of the tree planters to attend with a photo and name of the tree they planted hanging from their neck. At that meeting, gather commitments for trees to be planted in 2020, especially during April, which is both Earth Day and Arbor Day month.
