Promising New Technologies
Although we have robust efforts aimed at slowing the spread of invasive species, the truth is that they are still spreading. In fact, it is likely that many of our waters may become invaded at some time. This reality has caused some critics to question why we even try to reduce the spread. They argue that we will ultimately lose so why spend resources on what they believe is a losing battle.

While I agree that invasives will continue to spread to new waters, I believe that our efforts to slow the spread are very important. One reason why is that by slowing the spread we are gaining additional time to develop new responses to invasion. The research community is working to develop new control methods and this month I want to feature a few examples of how we are gaining new tools and understandings that may allow us to more successfully control invaders in the future.

Researchers at Stephen F, Austin State University have developed a totally new concept and approach to controlling the invasive aquatic weed giant salvinia. The technique is called “endocides” (endogenous biocides) and has been extensively tested in greenhouse experiments on the SFA campus. This new approach offers great promise for developing new controls for a difficult invader. Read More

Controlling invasive zebra and quagga mussels has been almost impossible as no control methods have proven to be practical. However, a long term research effort is now providing promising results. Researchers have found that the bacterium, Pseudomonas fluorescens strain CL145A, kills the mussels but appears to have little or no effect on other organisms. Extensive testing of this naturally occurring soil bacterium has been, and is being, conducted and a commercial product offers great promise. Read More

Unrecognized Invaders?
Forest pest insects are a serious threat to all types of trees. Whether in wild forests, urban parks, planted orchards or in shopping mall parking lots, our trees are threatened by these invasive insect pests. The best way to address the problem is to quickly identify new pest insect introduction so they can be eliminated before they spread. However, to catch introductions early we need a lot of trained observers watching for the pests.

This is where the fly fishing community comes in. Few people spend more time looking at insects and knowing what they are seeing than fly anglers. This makes them a perfect group to learn about forest pests so they can be part of the early detection effort. With support from the US Forest Service and the USDA APHIS, the Invasive Species Action Network has Created the Forest Pest Fly Tying Project. The program uses demonstration fly tying to teach anglers about the pests we are most concerned about and is a great way to get fly anglers involved in this important conservation effort.

The Forest Pest Fly Tying Project will be conducting demonstration at a number of sporting shows and other venues in the next few months and we are seeking fly tiers from around the country to join in the conservation through fly tying project.

All across the USA boat inspection programs it is the hiring season for boat inspectors. There are lots of jobs for inspectors in many different states and now is the time to apply. If you know anyone who might be interested in protecting our waters encourage them to contact their state agencies to find out how to apply.
