Ohio develops method for assessing invasive species
A science-based effort is underway to identify invasive plants from other regions and reduce their impact in Ohio, according to the Ohio Invasive Plants Council (OIPC).

A 22-question assessment protocol was developed in 2012 by the OIPC and other stakeholder groups. A five-person assessment team of researchers and botanists will evaluate potential invasive plants and establish a new list of primary offenders.

Concurrently, the assessment team will provide a list of alternative plants suitable for recommendation to nurseries, garden retailers and homeowners. The team will initially evaluate 27 problematic invasive plants. The team will address a second group of plants within a year, including those produced and sold in Ohio nurseries, such as ornamental pear, Japanese barberry and burning bush.

USDA proposes updates to plant import regulations
The USDA Animal and Plant Health Inspection Service (APHIS) is proposing to make several amendments to update and streamline its regulations involving the importation of plants for planting.

Some of these proposed changes include requiring permits for the importation of certain coated or pelleted seeds, and providing for an alternate additional declaration on phytosanitary certificates that accompany plants from countries known to have potato cyst nematodes. The proposed regulations also change provisions specific to certain countries, to ensure they reflect the latest information regarding quarantine pests detected in various places.

These improvements will make the existing regulations current, provide a faster and simpler process for industry, and maintain the existing level of protections for U.S. agriculture.
