The plant can negatively impact water-based recreation, recreational and commercial fishing, and local economies. Conditions in these water bodies do not appear to limit the plant\u2019s spread and it is difficult to eradicate. Catching&nbsp;<em>Hydrilla<\/em>&nbsp;early enough in its spread allows for more efficient control and higher potential to protect coastal rivers and sounds.<\/p>\n\n\n\n<p>North Carolina Sea Grant is coordinating with other agencies and communities to improve our understanding of how&nbsp;<em>Hydrilla<\/em>&nbsp;is spreading in the Albemarle watershed.

Place any suspicious vegetation in a trash bag and get rid of it at a plant disposal station or trash receptacle, or on the ground in an area well above the high-water mark.<\/li>\n\n\n\n<li>Look for material trapped between the boat and trailer, inside any open tubing on the trailer, and around taillights and license plates.<\/li>\n\n\n\n<li>Drain, dry and clean bilges, drop keels, live wells and anything else on the boat that can retain water before moving to another water body.<\/li>\n\n\n\n<li>Allow boats and trailers to fully air dry (five days or more is preferable) so any hidden plants will completely dry out between boating in different bodies of water<em><strong>&nbsp;OR<\/strong><\/em>&nbsp;take boats and trailers to the nearest car wash for a good cleaning.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Marina Owners<\/h4>\n\n\n\n<p>Here are some steps marina owners can take:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Train marina staff to identify&nbsp;<em>Hydrilla<\/em>&nbsp;and inform boaters of what to do if they find the weed.<\/li>\n\n\n\n<li>Inform all boaters about the current&nbsp;<em>Hydrilla<\/em>&nbsp;status.<\/li>\n\n\n\n<li>Promote the importance of clean boating practices to boaters.<\/li>\n\n\n\n<li>Check and clean lifts and trailer equipment in the boat yard each time they are used.<\/li>\n\n\n\n<li>Consider building a&nbsp;plant disposal station. Make sure your boaters know where they are and how to use them correctly.&nbsp;At a minimum, designate an area high above the water line where any vegetation removed during cleaning can be disposed of safely. Students from J.A. Holmes High School in Edenton are helping to install stations at Wildlife Resource Commission boat ramps throughout Chowan County.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Citizen Scientists<\/h4>\n\n\n\n<p>Consider becoming a&nbsp;<em>Hydrilla<\/em>&nbsp;Guerilla.

Any activity that cuts or breaks apart weeds carries the risk of spreading fragments to other areas, especially with&nbsp;<em>Hydrilla<\/em>. Additionally, hand harvesting&nbsp;<em>Hydrilla<\/em>&nbsp;is not effective long-term control because if you do not remove the entire plant, including the tubers buried deep in the soil, it will re-sprout.<\/p>\n\n\n\n<p>If you attempt to remove&nbsp;<em>Hydrilla<\/em>&nbsp;by hand, minimize fragmentation and capture all pieces. Large fishing nets can be used to help catch some of the fragments, although they are not likely to get all of them.<\/p>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-ncst-accordion-item ncst-accordion-item panel\"><a class=\"accordion-item__header collapsed\" href=\"#ncst-accordion-item-0-1\" id=\"ncst-accordion-item-heading-1\" data-toggle=\"collapse\" data-target=\"#ncst-accordion-item-0-1\" aria-controls=\"ncst-accordion-item-0-1\" rel=\"noopener noreferrer\"><span class=\"accordion-item__expansion-indicator\"><span class=\"ncst-plus-minus-toggle\"><\/span><\/span><h2 class=\"accordion-item__label h5\">Report Suspects<\/h2><\/a><div class=\"collapse panel-collapse accordion-item__content-container \" id=\"ncst-accordion-item-0-1\" aria-labelledby=\"ncst-accordion-item-heading-1\" data-parent=\"#ncst-accordion-0\"><div class=\"accordion-item__content\">\n<p>Look for&nbsp;<em>Hydrilla<\/em>&nbsp;in creeks, rivers, bays and elsewhere, especially in the spring through autumn.<\/p>\n\n\n\n<p>If you think you have found a&nbsp;new&nbsp;infestation of&nbsp;<em>Hydrilla<\/em>, help state agencies track the plant by reporting the sighting through one of the options below.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Online to the N.C.
