a There was a total of 505 acres of yew grown.
b There were 9 growers in the stat.
White-tailed deer, Odocoileus virginianus
Deer are credited as much with the decline in acres grown to yews as are root weevils. Many nurseries that grew yews 5 - 10 years ago no longer do so because of excessive deer damage (principally in coastal areas). Though deer browsing in the nursery can be a problem, the greater impact has been on the marketability of yews. Customers choose to buy other, deer-resistant plant species rather than yews.
Numerous sprayable antifeedant products are available. However, only one grower used an antifeedant product, Thiram, on his yews. This use amounted to less than 1% of the total acreage, which included about 1 pound of active ingredient. One grower obtained a damage permit and killed many deer in the nursery.
