Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Smarty Plants on Invasive Plants
Answered by: Jil M. Swearingen, National Park Service

QUESTION:

How bad are invasive species?

ANSWER:

Invasive species impact native plants, animals, and natural ecosystems by, reducing biodiversity, altering hydrologic conditions & soil characteristics, interfering with natural succession, competing for pollinators, displacing rare plant species, serving as reservoirs of plant pathogens, replacing complex communities with single species monocultures, & diluting the genetic composition of native species through hybridization. Browse the links of our Plant Conservation & Landscape Restoration programs on-line to discover more of what you can do to nurture native plant species in your eco-region.
