Human Impact
Lily leaf beetles leave considerable damage on host plants. Managing ornamental lilies has become difficult in regions where lily leaf beetles have established. Damage to the leaves and flowers can also leave the plants weakened and susceptible to diseases such as Lily grey mold.
The Canadian Maritime provinces, especially Fritillaria and Lilium gardens in Halifax, are largely affected by lily leaf beetles. A garden in Waverly, Nova Scotia has reported decline of lily species and cultivars from 50 in 1996 to only one species in 2006.

Famous quotes containing the words human and/or impact:
“Without the Constitution and the Union, we could not have attained the result; but even these, are not the primary cause of our great prosperity. There is something back of these, entwining itself more closely about the human heart. That something, is the principle of “Liberty to all”Mthe principle that clears the path for all—gives hope to all—and, by consequence, enterprize [sic], and industry to all.”
—Abraham Lincoln (1809–1865)
“Too many existing classrooms for young children have this overriding goal: To get the children ready for first grade. This goal is unworthy. It is hurtful. This goal has had the most distorting impact on five-year-olds. It causes kindergartens to be merely the handmaidens of first grade.... Kindergarten teachers cannot look at their own children and plan for their present needs as five-year-olds.”
—James L. Hymes, Jr. (20th century)
