Remembering LeRoy Creswell (Florida Sea Grant)

On October 27, 2020, LeRoy Creswell (on the right in the blog header image) passed away after a long battle with cancer. Many in UF/IFAS Extension remember LeRoy as the Sea Grant agent in St. Lucie County, a position he held from 2000-2011. During this time, he was one of the early presidents of the Florida Association of Natural Resource Extension Professionals. From 2011 until his retirement in 2019, he served as an Extension program manager for Florida Sea Grant.

What people may not realize is the depth of his reach beyond UF/IFAS and Florida Sea Grant.

LeRoy Creswell talking with colleagues and students Before working for UF, LeRoy worked at Harbor Branch Oceanographic Institution in Fort Pierce, FL, where he directed the tropical aquaculture laboratory. It was in that role where John Scarpa (now an associate professor at Texas A&M University and president of the National Shellfisheries Association) first met him. John says, “I was fortunate to have met LeRoy early in my career when I was a postdoctoral associate at Harbor Branch Oceanographic Institution. He warmly welcomed me and not only did I have a new colleague but a lifelong mentor and friend. He introduced me into the world of professional society service as he volunteered for so many different professional organizations. We even ran against each other for one position in the National Shellfisheries Association; yes, I lost and with no regrets. Although professional society volunteering kept us close, his time at FL Sea Grant allowed us to continue a research and education relationship as we explored new species for aquaculture. I will miss his warm smile and vast knowledge of literature and music that made for great conversations.”

After joining Florida Sea Grant, LeRoy was known for reaching out to new extension agents, as you can read in this tribute on the Florida Sea Grant website. His cheerful attitude, and (sometimes quirky) sense of humor were always appreciated, as were his musical talents and his love of dogs. He also had an incredible work ethic and was very active in professional associations, including the Gulf and Caribbean Fisheries Institute, the World Aquaculture Society and the National Shellfisheries Association.

The following tribute will be included in the proceedings for the 2020 GCFI meeting, which was held November 2-6, 2020. “LeRoy served as the Executive Secretary and Senior Editor of the annual Gulf Caribbean Fisheries Institute Proceedings for the previous 18 years. He was an institutional pillar, not only through his official responsibilities, but also through the generosity and warmth he gave to all, especially to students and early-career professionals ready to become part of the GCFI family. In life, he was a charismatic presence, generous with his knowledge and wisdom, and a clarion voice for marine aquaculture and sustainable resource management in the U.S. and the Caribbean. His contributions to GCFI will remain with us forever.”

You can read many additional posts on his Tribute Wall. Feel free to add your own memories of LeRoy to share with his wife, Danita, and daughters Leala and Alonnah. Thanks to John Scarpa for sharing the photographs used in this blog post.

"An estimated 11 million metric tons of plastic ends up in oceans every year, a number that could triple by 2040 without serious action." This quote from an American Beverage Association article piqued my interest in plastics. Thank you for the thorough, well-written mini-lesson explaining the subject. Job well done!

Are you able to speak about the strength of the various substances mentioned in this article? Because I have very thick, long, wiry, and gray hair; I try to purchase styling accessories (clips, pins, barrettes, etc. ) made of acrylic or cellulose because I think they may be stronger and more flexible, although they are more costly than some "plastic" items. My experience has been that the rigid "plastic" varieties break easily. Is this true or can you recommend other materials that can be used for the same type of application? Thank you, Dorothy Grifka 619-693-5057

Thank you for your feedback, Frank. Here are a couple of links to our EDIS documents on beneficial insects. The following links include more of the commonly seen beneficial insects: https://edis.ifas.ufl.edu/topic_beneficial_insects and https://mrec.ifas.ufl.edu/lso/BANKER%20IST/Beneficial%20Insects%202.pdf that you can cut and paste into your browser. Though not an exhaustive compilation, they are a good start for identifying beneficial insects in your garden. Have a great day!

Just read your article, which describes exactly our recent experience. We live part time at at Crescent Beach. On a New Years Eve beach walk we encountered thousands of these Jellies on our beach. We counted 200 every 100 yards or so of beach. Now I know why. Thanks! Info provided by my friends at Whitney Labs.

Hi Lauren, I've checked with some of our plant restoration experts and they say there probably isn't anything that you can do to improve the chances of recovery, but that the plants are surprisingly resilient, so hopefully most will do just fine given a little time...

Lauren Levy

I am a homeowner in Pinellas County. We lost about 40% of our summer planting during Tropical Storm Eta. Is there anything you recommend we do for the remaining plants to help them recover, or is best to leave them alone, and let Mother Nature take care of it?

Leroy was a household name in global aquaculture in the 1980s and 90s, serving as President of the World Aquaculture Society in 1994 when I was a graduate student in Germany and in the UK. Someone who knew so much and gave so much his whole life. Rest in Peace, Leroy!

LeRoy joined our St. Lucie Extension office in the year 2000 and was an instant fit with our crew. He amazed us with all the projects he was involved in already and then he added more. He made sure we all got some of the farm raised shrimp from the IRREC project next door! He always spoke so proudly of his wife and daughters. He will be missed.

Thanks for taking the time to reply. You're lucky that you have the time to comment in great detail on more than one of my recent posts. I love trees and my Masters Thesis was on the Reforestation of Golden Gate Park due to my interest in urban forestry. And yes, I'm well aware of laurel and "water" oaks tendency to hollow out and lose limbs from fast-growing narrow-crotched branches. I'm also aware that live oaks can live a long time but are still susceptible to toppling over in hurricanes or losing their root system from constant salt intrusion. I don't have that much trouble distinguishing between oaks because of their leaf characteristics and especially their highly contrasting bark texture. Thanks again for your interest.

If I lived near beaches where these turtles nest and leave hundreds on eggs to hatch, I would love to walk the beaches and inform visitors about the necessity of leaving the nests alone, and allowing plenty of room around them. Alas, I live in Michigan.

Hi Gerry, I am going to forward your question about funding to my colleague Erik Lovestrand in the UF/IFAS Extension Franklin County Office (elovestrand@ufl.edu) as he may be more aware of support that might be available in your area. The manual "Dune Restoration and Enhancement for the Florida Panhandle" might also be of interest--you can find it at https://edis.ifas.ufl.edu/pdffiles/SG/SG15600.pdf. It recommends planting sea oats between December and April, with preferred dates being in March and April. Maia McGuire

We are also trying to restore the dunes and sea oats on a section of Carrabelle Beach on the Gulf Coast near Apalachicola after Hurricane Michael leveled the dunes and the sea oats. Are you aware of any local, state or federal programs to help on the purchase of the sea oats. We have already done a lot of work on the first steps to reestablish the sand dunes. Also, what is the best time to plant? THANKS for any suggestions you might have.

Hi Jack, sorry for the delay in responding--we are in the process of hiring a new horticulture agent. I am not sure why the link did not work for you--it is correct. Flagler County is considered to be outside the growing area for mangoes, although that could change as temperatures warm. Currently the northern limit for growing is Merritt Island (Brevard County). See https://edis.ifas.ufl.edu/pdffiles/MG/MG21600.pdf for more information.

Maia, I enjoyed your informative article on Shells of pteropods on local beaches. Especially the information on Creseis acicula.. I live in Delray Beach and have looked on our beaches but have not found this sea butterfly. Do you know where I could find, have, buy, a couple of this shell for a scientific exhibit on Sea butterflies? Thank you, Anne DuPont, akdupont@bellsouth.net

Thank you for this article. St George Island here. I followed your suggestions, including the use of hydrating polymer (despite having been discouraged from using this material by others). Planted 1200 liners over about 1 month. Last plantings dome about 6-8 weeks ago. 97-98% survival rate with great majority thriving!

Hello, I really appreciate this information. Thank you for making the information easy to understand because I do not have a strong chemistry background. Anyway, I came across your article because I was thinking about suggesting switching the plastic cutlery my company uses to biodegradable plastic cutlery. I am making a conscious effort to use less plastic. If my company does not practice composting, how do you suggest we start? For reference were located in Oxnard, Ca. Also, what is your opinion on using wood cutlery. Is this a good option? Thanks, Nadine

Maia McGuire

The answer somewhat depends on the quantities you will be needing--there are a few wholesalers listed on the Florida Association of Native Nurseries' website. However, they only sell wholesale. If you are looking for a retail outlet, there are a few retailers listed here. You may also be able to work with a local nursery and have them purchase from a wholesaler and then re-sell them. The sources listed on the websites may not be the only ones (the websites only list members of the Association of Native Nurseries), but they are a good starting point. I hope this helps!

Hi Janet--you might want to check out some of the activities on the K-12 page at www.plasticaware.org. Unfortunately there is no simple answer, and there is always the risk of making the problem seem so big that people may feel hopeless to do anything. I think it's best to focus on small acts--if every student in the class did not use one straw a week, for example. In a year, each student would have prevented 52 plastic straws from being thrown away. For a class of 20 students, that's 1,040 straws! This may help them realize that one person can make a difference, and if they can get others to take simple actions, their efforts will be multiplied greatly! Feel free to contact me directly at mpmcg@ufl.edu.

Maia McGuire

Hi Jack. That's a great question. The thought seems to be that the population of pteropods increases based on food availability. Winds and currents can affect where the pteropods are located and whether (and when) the shells will get washed up on beaches. It isn't an uncommon occurrence in Florida (considering the state as a whole), but often occurs over a relatively small stretch of beaches at a time. The shells can wash back into the ocean with subsequent tides, so they may only be apparent on a particular beach for a few days.

Jack Putz

Great explanation, but why are there so many on the beach...I've never seen them before...what happened or what is happening?

Wondering if we could plant sea oats as part of a Median landscape in Gainesville, Florida, or are sea oat plantings restricted to coastal areas and prohibited inland?

Maia McGuire

September 7, 2018

Whether or not you need a permit (in Florida, the permits come from the Department of Environmental Protection) depends on the size of the area to be planted, whether or not a sprinkler/irrigation system will be installed, etc. You may be required to coordinate with the local sea turtle patrol if planting will be done during sea turtle nesting season (to ensure no damage is done to nests that may be in or near the area to be planted. You can find your local DEP contact at https://floridadep.gov/water/coastal-construction-control-line/content/district-field-representatives-contact-list. That person will be able to advise you as to whether or not you need a permit (and if so, how to go about obtaining one).

Hi Nancy, There is one retailer near you listed with the Florida Association of Native Nurseries (www.afnn.org). 7 Pines Native Plant Nursery is in Defuniak Springs, and it sells sea oats in gallon pots, according to the website. There may be other retailers who carry sea oats but are not members of that association. Hope t his helps!
