Keynote: Insect Apocalypse? What Is Really Happening, Why it Matters and How Native Plants are a Vital Part of the Solution by Scott Hoffman Black, Executive Director, Xerces Society for Invertebrate Conservation, www.xerces.org
- You can thank insect pollinators for 1/3 of every mouthful of food that you eat.
- Without small flies in streams for young fish to eat – your last grilled salmon would have been impossible.
- If you like songbirds, you can thank an insect – 96% of birds rely on insects for survival.
With well over one million known species, insects and other invertebrates eclipse all other forms of life on Earth. They are essential to the reproduction of most flowering plants, including many fruits, vegetables, and nuts; they are food for birds, fish, and other animals; they filter water and help clean rivers and streams; and they clean up waste from plants and animals. Just four of the many insect services—dung burial, pest control, pollination, and wildlife nutrition—have an estimated annual value in the United States alone of at least $57 billion. They truly are the “little things that run the world.”
Though they are indisputably the most important creatures on earth, invertebrates are in trouble. Recent regional reports and trends in biomonitoring suggest that insects are experiencing a multi continental crisis evident as reductions in abundance, diversity and biomass. Given the centrality of insects to terrestrial and freshwater aquatic ecosystems and the food chain that supports humans, the potential importance of this crisis cannot be overstated.
Native plants and insects are the fabric of the planet. These plants and animals have evolved together to form food and energy webs that are vital for all life on earth. If we hope to stem the losses of insect diversity and the services they provide, society must take steps at all levels to protect, restore and enhance native plant habitat across landscapes, from wildlands to farmlands to urban cores. Protecting and managing existing native plant habitat is an essential step as natural areas can act as reservoirs for invertebrate diversity.
Scott Hoffman Black will explain the latest science on insect declines and highlight important ways everyone can incorporate invertebrate conservation into their lives.

Breakout Session 2
- New to Natives Track: Kill Your Lawn and Save Colorado by Jim Tolstrup
- The average person in Colorado uses 90 gallons of water every day on landscaping alone. With a changing climate and a rapidly growing population our current rate of water consumption is unsustainable. As a result, our rivers are drying up and opportunities for habitat creation within our landscapes are being lost. For over a decade, Jim Tolstrup and the High Plains Environmental Center have been promoting the use of beautiful, water-saving, native plants in landscaping. They have also been helping Homeowners, HOAs, and Developers to establish new native grass areas and convert thirsty turf grass into native grass. Jim will take participants through a step by step process for establishing native grass, including timelines, costs, different grass types, and long-term management strategies.
- Jim Tolstrup is the Executive Director of the High Plains Environmental Center in Loveland, CO, a unique model for preserving native bio-diversity in midst of development. His past work includes serving as Land Steward of Shambhala Mountain Center, and running his own landscape design business in Kennebunkport, Maine where he installed gardens at George and Barbara Bush’s “Summer White House.” Jim received a Certificate in Gardening Arts from the Landscape Institute of Harvard University and the Arnold Arboretum. He teaches widely throughout Colorado, has written numerous articles on gardening and environmental stewardship, and has received awards for landscape design from, Plant Select, ALSA, ALCC, and Denver Water.

- Knows the Natives Track: The Good, The Bad and the Ugly: IPPM for Native Gardens by Amy Yarger
- Pests and weeds make up a small percentage of the species we encounter, and yet they have a significant impact on our landscapes, our pocketbooks and our peace of mind! In response, many native plant gardeners seek an approach that will protect the plants and the other beneficial organisms they rely on. Amy will present examples of Integrated Pollinator and Pest/Weed Management (IPPM), a maintenance framework that takes these considerations into account for healthier, more resilient landscapes.
- Amy Yarger has worked in the public horticulture field since 1996. She received a bachelor’s degree in ecology and evolutionary biology at the University of California, Irvine and then went on to study plant-animal interactions at the University of Michigan. Her master’s thesis concerned the effects of noxious weeds on pollinator-plant relationships. Her work at the Butterfly Pavilion, where she has worked since 2000, touches on many of her passions: plants, insects, habitat conservation and science education. She is currently on the board of the Colorado Native Plant Society, where she serves on the Horticulture and Education and Outreach committees.
