Many trees were still standing after the storm, but inundation by salt water killed them where they stood. The only plants that survived were native dune and marsh grasses.
The dunes on Galveston Island were badly eroded, but in some places with robust dunes, the vegetation held enough of the sand in place to prevent massive erosion. The beaches are ragged but still standing (and so are the building behind them). Beaches in front of the seawall had no vegetation to guard against erosion, and those beaches eroded and are now underwater.

We installed ASUs with dense and sparse canopies made from polypropylene ribbon. Half were enriched and half were not. After 3 months, it seems that epifauna were more abundant in enriched plots, regardless of canopy density. This is a qualitative assertion, however--canopy effects may not be as strong (and therefore not as visually obvious) as nutrient effects. Carolyn is looking forward to many weeks of sorting, identifying, and enumerating these creatures to find more definitive answers to our questions.

Required qualifications: Ph.D. or equivalent in Biology, Ecology, or related field.
Additional qualifications desired: Experience with field ecology methodologies, community ecology, use of stable isotopes, productivity measurements; strong writing skills.
Special requirements: Physical ability to conduct research in the hot and humid conditions typical of
Responsibilities: The associate will be expected to conduct independent research, provide some assistance to graduate students, write research articles, and generate reports for the funding agency.
Start date is September 1, 2008. For full consideration, submit applications by July 1, 2008. Submit TAMU application, statement of interest and experience, and CV at the online submission website, tamujobs.tamu.edu (NOV# 081262). In addition, please have three references submit letters of recommendation directly to Dr. Anna Armitage (email@example.com) with a cc to Betty Thompson (firstname.lastname@example.org).
Graduate student: Wetland Restoration Ecology
Department of Marine Biology,
We are seeking a M.S. or Ph.D. student to participate in a two-year project assessing the effects of landscape engineering (e.g., sediment source, hydrology) on restored brackish marsh ecological functions. Possible research fields include patterns of productivity, carbon sequestration, and the development of food webs in restored marshes.
Required qualifications: B.S. or equivalent in Biology, Ecology, or related field.
Additional qualifications desired: Relevant coursework or experience with field ecology methodologies, community ecology, use of stable isotopes, productivity measurements; strong writing skills.
Special requirements: Physical ability to conduct research in the harsh heat and humidity typical of
Responsibilities: The graduate student will be expected to conduct independent research and assist with generating reports for the funding agency.
Desired start date is Spring 2009. Application deadline is July 2, 2008 or until a candidate is selected. Send statement of interest and experience, CV, unofficial transcripts, GRE scores (if available), and three letters of reference in electronic format to Dr. Antonietta Quigg (email@example.com).

But on our way upstream we encountered a female alligator who made it very clear that we were not welcome in that area (probably a nest nearby). She herded us several hundred meters downstream. We might have felt less vulnerable if we weren't in canoes, eye-level with the gators. We'll try to use a pontoon boat for the next trip.
Other wildlife was more friendly, like this frog that hopped along the gunwale, up onto my knee, and then back into the water.
UPDATE: Turns out, the pontoon boat was in the shop. But, a smaller team was able to squeeze by the alligator the following day and complete the sampling upstream. Good work!

The Texas General Land Office has awarded a research grant to myself and Dr. Antonietta Quigg to study the efficacy of different restoration techniques in brackish marshes in north Texas. Mounds were created in degraded open water habitat using different pumping and dredging methods and sediment sources. We will be studying these restoration methods using surveys and field experiments. Potential grad students and postdocs: keep an eye on this blog for upcoming job postings...

The sewage is treated, but it's unknown how many nutrients the outfall contributes to the Bayou, or how its output influences the growth and establishment of restored marshes downstream or the invasive plants that are spread throughout the Bayou.
Welcome to Allison Parnell--she will be seeking answers to these questions and more for her master's thesis.

And others were mounds surrounded by dredge fill:
What are the advantages and disadvantages of these methods? Which are the most ecologically successful? These are the next questions my lab will address. See more photos here.
