CDFA Pest Prevention Plant Regulation Practice Exam

A shipment of elm trees from Arkansas should be:

1. A. fumigated with methyl bromide and released

2. B. rejected

3. C. inspected, if the inspection findings are negative, release

4. D. held for permit from the director

The correct answer is: B. rejected

In the context of transporting elm trees from Arkansas, the shipment should be rejected due to the potential threat posed by pests such as the invasive Thousand Cankers Disease. This disease significantly affects elm trees, leading to severe damage and mortality. The regulations surrounding the movement of these trees are stringent to prevent the introduction of harmful pests into new areas. While options that involve fumigation or inspection may seem viable, they do not adequately address the core concern of preventing the spread of established pests associated with elm trees from infected regions. Rejecting the shipment is a proactive measure to ensure biosecurity, protecting local ecosystems from external threats that could arise from introducing infected materials.
