Symptoms include dark stripes between leaf veins, thickening and curling of leaves, and canopy thinning. Contact VDOF's forest health program if you see these symptoms. For more information, view this Beech Leaf Disease Pest Alert (Jan 2021) [PDF, 312 KB] publication.

Natural Resources Stewardship staff (NRS) has determined that many non-native invasive plants (NNIs) known to present a significant threat to the quality and biodiversity of the natural areas occur in this 37,000-acre park system. To support the park mission to steward these lands, Montgomery County Department of Parks has prepared fact sheets for park managers and maintenance personnel with easy-to-read information about mechanical and chemical control methods for several terrestrial NNIs.

Motorboats and sailboats must have an ANS Stamp prior to launching vessels in Colorado (effective Jan 1, 2019). Boat owners are required to purchase the ANS Stamp and operators must retain proof of purchase (electronic or printed receipt) on his or her person, the motorboat or sailboat, when operating the vessel (C.R.S. 33-10.5-104.5). Funding contributes to prevention and management of ANS in the state. Thank you for protecting our waters and contributing to conservation in Colorado!

Louisiana Department of Agriculture and Forestry.
In May 2010 the last boll weevil was trapped in the state and in March 2012 the boll weevil was declared eradicated from the state of Louisiana. The Eradication Program is now at a maintenance level, funded through grower maintenance inspection fees. Traps are placed and monitored according to an approved trapping protocol. Cotton producers have seen increases in yields along with a reduction in the cost of insect control.

New Hampshire Department of Agriculture, Markets, and Food.
Boxwood blight (Calonectria pseudonaviculata, BB) kills plants in the family Buxaceae, including boxwoods, pachysandra, and Sarcococca. It was first detected in the U.S. in 2011, and many states have implemented requirements for boxwoods to have been grown in a certified “clean boxwood” program to ship into their state. When this disease is found in New Hampshire nurseries, infected plants are required to be destroyed. BB has been rarely found in managed boxwood plantations in the state. Care is recommended when introducing new boxwood plants into existing plantations as the disease can be latent and difficult to detect. The Horticultural Research Institute has best management practices guidelines for production and landscape managers.
