Opportunities abound in cities, towns, and campuses to support bees, butterflies, and other wildlife. Many outdoor spaces—from parks and school grounds to roadsides and business campuses—can provide valuable pollinator habitat. Along with new habitat, pollinators need protection from pesticides. Thoughtful pest management efforts work to reduce pesticide use and mitigate risks when pesticides are used. Such efforts can enhance the value of pollinator habitat and serve communities, offering a variety of benefits such as keeping children safe and protecting water quality.
Artificial light at night, or ALAN for short, may be one of the main drivers of firefly declines. At least 80% of the firefly species found in the United States and Canada communicate with each other using bioluminescent light signals in the form of flashes, flickers, or glows. These species are active at dusk or after dark, and artificial lights that are on at this time can make it harder for them to see each other. It may also make fireflies more vulnerable to predators that would otherwise be repelled by their light.
In 2018 and 2019, the number of monarchs overwintering in California dropped to 1% of the historic population size. In 2020, that number dropped even further to less than 0.01% of the historic size, volunteers counted less than 2,000 monarchs during the annual Western Monarch Thanksgiving Count. For every 2,250 monarchs there were 30 years ago, there is only one left flying today.
