2020 Virtual Meeting


Texas Aquatic Plant Management Society
Virtual Meeting
November 17, 2020
12 – 5 pm

Due to the ongoing COVID situation, the TAPMS board felt it best to cancel the in-person meeting for this year. However, we still wanted to provide our members the opportunity to receive their 2021 TAPMS membership and CEUs credits. As such, TAPMS will have their first virtual meeting on November 17, 2020 from 12pm-5pm. During this meeting, there will be five CEU presentations with short breaks or meeting sponsor presentations in between. We would also like to vote on 2021 TAPMS Board members during this virtual meeting. A poll will be sent out during the meeting for members to vote and results will be announced at the end of the meeting. Please send TAPMS board member nominations to Kristy Kollaus (kkollaus@edwardsaquifer.org).

The cost for the 2020 TAPMS virtual CEU course is $80. This includes your TAPMS 2021 membership fees. Once you register, we will send you a link to the virtual meeting and further details once we get closer to the meeting.

Sponsorship levels for the TAPMS virtual meeting are also available starting at $200 up to $1,000. These sponsorships will greatly contribute to student scholarships in 2021. Virtual meeting sponsors will be announced during the meeting and listed during meeting breaks and on the TAPMS website and newsletters. The Silver Level Sponsor ($500) and Gold Level Sponsor ($1,000) can have a short presentation during the virtual meeting. Each level of sponsorship will receive TAPMS memberships and virtual meeting registrations included. (Please email Kristy Kollaus with any further questions regarding the virtual meeting sponsorships.)

Important Information: During the virtual meeting, we will also hold polls with simple questions at the end of each CEU presentation. This is a requirement of the TDA to ensure participants are watching the entire presentation. You will need to answer these questions in order to receive the CEU credits. We will have individuals to help with technical issues during the meeting.

Thank you TAPMS members for you continued support during this trying time and we hope to see many of your faces on our first TAPMS virtual CEU meeting! Please see the course agenda below as well as presenters and presentation summaries. We will continue to update the agenda to include sponsor presentations.

TAPMS Presentation Summaries

Statewide Integrated Pest Management of Aquatic and Riparian Invasive Species

John Findeisen and Monica McGarrity

This presentation will provide an update on Texas Parks and Wildlife Department’s aquatic vegetation and invasive species management efforts in Fiscal Year 2020 (Sept. 2019 – Aug. 2020), with a focus on implementation of an Integrated Pest Management (IPM) strategy. Texas’ IPM strategy employs a combination of prevention, herbicide treatments, biological control efforts, and outreach for not only prevention but also to promote environmental stewardship (e.g., enhancing creek health) and involvement in citizen science monitoring efforts. Early Detection and Rapid Response (EDRR) capacity is vital to efforts to monitor for new infestations of the most problematic species such as giant salvinia (Salvinia molesta) and zebra mussels (Dreissena polymorpha) and mount a rapid response when feasible. Management efforts continue to focus on floating, aquatic invasive plants and riparian invasive plants that crowd or shade out native plants, degrade habitat for fish and wildlife, and inhibit boater access. Management of aquatic and riparian invasive species using an IPM approach plays a key role in conserving Species of Greatest Conservation Need (SGCN) and providing hunting, fishing and outdoor recreation opportunities for the use and enjoyment of present and future generations.

Drift Minimization: Maximizing your chemical investment… When bad things happen to good droplets

Chris Smith

There is a need to make sure spray applications reach their target. Maximum coverage is needed for optimal pesticide performance. Maximum coverage is needed to reduce the movement of pesticides to non-target areas. There are many factors that affect whether a spray application reaches its target. Actions can be taken to reduce spray movement and ensure spray applications reach their target. Topics covered in this presentation include: What is spray drift? Why is reducing drift important? What factors affect drift? What can be done to limit spray drift?

Golden Algae – Toxic Fish Killer in Texas

David Buzan

“Golden algae, Prymnesium parvum, was first identified as a causative agent for a major fish kill in the Pecos River in Texas in 1985. Historical fish kill records indicate a large fish die-off in the Pecos River on the Texas-New Mexico border and in Red Bluff Reservoir was also caused by golden algae. Since that time, golden algae has spread to the Colorado and Brazos river basins, killing tens of millions of fish in major reservoirs like Possum Kingdom, Granbury and Whitney. It is now recognized as a fish killer in a number of states in the continental U. S. Originally recognized as a brackish algae, it gained fame in the 1960’s and 70’s killing fish in brackish water aquaculture ponds in Israel. Although it has been found in other environments (coastal waters of Texas and some east Texas reservoirs) it seems to cause fish kills in higher conductivity/higher pH water bodies.

David Buzan has investigated golden-algae caused fish kills across the state since 1985. He currently analyzes water samples from private ponds experiencing fish kills to determine if golden algae caused the fish kills. He sees golden algae fish kills occurring in ponds fed with brackish groundwater in south Texas. These kills typically occur from the spring into the summer. Some of his clients have also seen golden algae fish kills in ponds fed with brackish water from the upper Brazos River.

Texas Agrilife describes a number of treatment options for the control of golden algae in private ponds and lakes. Researchers at Texas Tech are investigating the use of extracts from giant cane as possible chemical controls. In this session, David will review the history of golden algae kills, golden algae biology, and observations on different control options like water quality management, liquid shades and chemical controls.”

Integrated Pest Management of Nuisance Aquatic Vegetation in Texas

Monica McGarrity

Control of nuisance aquatic vegetation in Texas waters often requires an integrated pest management approach with the best control method being identified and used for the individual situation. Nuisance aquatic vegetation management in Texas—regardless of method—must be done in accordance with the State Aquatic Vegetation Plan following key treatment approval and/or permitting processes for most activities. This presentation will discuss integrated pest management strategies and provide detailed guidance on understanding and navigating these requirements for implementing chemical, mechanical, biological, or cultural control methods in compliance with the state plan to successfully manage aquatic plants.

An Overview of Important Aquatic Plant Families in Texas and Comparisons in Field Identification

Casey Williams

The term “aquatic plant” is broad and covers a wide range of vascular plant families some of which share very similar characteristics between their aquatic representatives. In this presentation I will cover the fundamental points on what constitutes an “aquatic plant”. Knowledge of lifecycle strategies, morphological characteristics and growth habits are all important for understanding what an aquatic plant is. I will also highlight and discuss some of the more important aquatic plant families in Texas (examples include the milfoil family, frogbit family, waterlily family and primrose family and more) and representative species from each family to help reinforce field identification between families, especially species that look similar but belong to different families, as well as comparison of species within families.
