INTRODUCTION

This study was designed to provide an inventory of the benthic infauna to compare with prevIousdata, and provide baseline information to determine the potential recovery rate from therestoration of upstream oxbows. Additionally, upstream limits to which estuarine fauna are ableto exist were established, allowing SFWMD to determine more accurately the amount and timingof freshwater discharge from the locks, minimizing potential adverse effects on the morestenohaline populations.

The study area extended from Redfish Point near the mouth of the Caloosahatchee River,upstream to Franklin Lock, just west of Hickey Creek. There were three components to the study:1) Analysis of the infaunal macroinvertebrates associated with re-vegetated beds (Figure 1); 2)Analysis of infaunal macroinvertebrates associated with 5 oxbows in the upper tidal portion of theRiver (Figure 2); and 3) Qualitative analysis of macroinvertebrate habitats associated with theoxbow regions of the upper tidal portion of the River.

Benthic invertebrates can be used as a barometer determining long term changes in water quality.Whereas chemical samples measuring water quality provide only a "snapshot" of currentconditions, a benthic inventory establishing changes of populations within the communitystructure can detect subtle perturbations in the watershed. Knowing the environmentalrequirements of the dominant taxa enables an accurate assessment of potential environmentalimpacts. Results from this study may be used to determine the benefIcial or deleterious effects ofrenewing the oxbows and altering the water flow from areas upstream from the Franklin Lock.

STUDY AREA

The Charlotte Harbor watershed is drained by three main rivers: Myakka, Peace, andCaloosahatchee. The Caloosahatchee River drains a basin of over 1,000 square miles extendingfrom the western border of Lake Okeechobee westward to where it enters the southern portion ofCharlotte Harbor at San Carlos Bay. The Caloosahatchee River discharge into the CharlotteHarbor system is the greatest of any of the three major estuaries, contributing, on average,approximately 70% of the total inflow making it one of the most significant hydrologic resourcesin Southwest Florida. The discharge of the River from Lake Okeechobee is regulated by a seriesof locks, retaining the water in the dry season as a reservoir and discharging water during therainy season. The Franklin Lock and dam (S-79) is the most downstream of these structures andprevents the upstream movement of saline water into the non-tidal region. The non-tidal regionof the Caloosahatchee River is of extreme importance in providing potable water for the urbanFort Myers area, and agriculture relies heavily on it for irrigation. In the mid to late 1960's, it waschannelized into a canal by the Army Corps of Engineers, eliminating approximately 35preconstruction oxbows of various sizes and geomorphic configurations. Currently, SouthFlorida Water Management District, through the Ecosystem Restoration Department hasestablished, in conjunction with the Florida Center for Environmental Studies, a CaloosahatcheeRiver and Estuary Ecological Research Team to study the restoration of preconstruction oxbowsin that portion of the river. Only one study of the benthos within the upper tidal region has beenconducted previously (SFwrvID, 1986), and encompassed only a short section

Sample Locations

Site selection was determined during a reconnaissance by representatives from the collaborativeagencies and institutions. Five sample sites (transects) were chosen from Shell Point to BeautifulIsland .. These locations were based on the submerged aquatic vegetation beds of Vallisnaria andThalassia established by Harbor Branch Oceanographic Institution, and currently being monitoredby SFWMD (Figure 1). Three sampling stations were established at each site. One station waslocated within the grass bed, another station established in an adjacent non-vegetated area, andone station established adjacent to the main channel. Sample sites were also established on thefive oxbows from Beautiful Island to the Franklin Lock (Figure 2). Three stations were locatedwithin each oxbow proper: an upstream station at the mouth of the oxbow; a downstream stationwhere the oxbow rejoined the main river; and an intermediate station in the middle of the oxbow.Qualitative samples were collected from the upstream and downstream regions associated withemergent vegetation.

METHODS

Sample Frequency

Samples were collected in June 1998 for the dry season. Subsequently, sampleswere collected in September 1998 for the wet season.

Field Methods

[nfaunal Collection

Infaunal benthic macroinvertebrates were collected using a diver operated coringdevice. Four replicate samples were collected. Three were analyzed, and oneretained as a backup. Each sample was rinsed through a 500 micron bucket sieve.The residue was rinsed into an appropriately labeled jar using a squirt bottle, fixedwith 10% formaldehyde solution stained with rose bengal, and an internal labelplaced inside the jar. Each label indicated the project, date, sample type, sampler'sinitials, location, and replicate number. Samples were placed in a water tightcontainer and transported to the laboratory. A custody sheet accompanied thesamples and signed by the sampler indicating the number of samples transported,date collected, fixative, sites, stations and replicates. All information recorded inlog books, and on labels and custody sheets were filled out in either pencil orindelible ink.

Qualitative CollectionQualitative samples were taken at each station located within the 5 oxbowsupstream from Beautiful Island to Franklin Lock concurrent with the infaunalsampling. Samples of coarse particulate organic material (CPOM) were analyzed.An unspecified number of handfuls of CPOM were rinsed in a #30 mesh sievebucket until a minimum of approximately 100 organisms were collected.. Sampleswere labeled and returned to the laboratory as per the preceding section

Laboratory Methods

Upon receipt of the samples at the laboratory, samples \vere inventoried andchecked for leakage. After a minimum of 48 hours the formalin was decantedfrom each sample, the residue rinsed with water though a 500 micron sieve andreturned to the original container, and preserved with 70% isopropanol.. A smallamount of residue was placed in a petri dish and examined under a variable powerdissecting microscope. The organisms were removed from the residue and sortedinto one of three labeled vials containing alcohol: annelids: chironomids; or

8

miscellaneous. This step was repeated for all residue.

After sorting, all organisms were identified to the lowest practical taxonomic level(LPIL). Oligochaetes, and chironomids were mounted in Ammon's lactophenol onmicroscope slides for identification. The organisms were then identified under acompound microscope, enumerated, and the results recorded on the appropriatebench sheets. If more than approximately 125 oligochaetes or chironmids wereencountered in anyone sample, they were subsampled The organisms were placedin a gridded petri dish. Each grid was assigned a number. A random number tablewas used to choose a grid. All organisms were removed from that grid. Thisprocess continued until at least 100 organisms were separated. The remainingorganisms were enumerated with the results recorded in the sorting log.

DISCUSSSION

Transects

Seventy taxa were collected from all stations throughout the study ( Table18 ). Polychaeta was the most diverse taxon with 16, followed by bivalves(11), chironomids (10), and amphipods (8). No insects were collected atany station, except Diptera, represented by chironomids (10) andceratopogonids (1).

In June the number of all taxa combined was 50 (Table 4), and 48 inSeptember (Table 12). Polychaetes and bivalves were the most diversetaxa in both months. Chironomidae was also highly diverse in September

Overall, only 14 taxa comprised over 10 % of the total communitythroughout the study: Nemertea; Tub(flcoides heterochaetus (oligochaete);Laeonereis cu/veri and Streb/o,\pio benedicti (polychaetes); Rangiacuneata, Macoma tenta, Po/mesoda carotiniana, and Tage/us divisusbivalves); Almyracuma nr. proximoclliae and Cycla.~pis varians(cumaceans); Cyathura polita (isopod); Grandidierella honnieroides(amphipod); and Procladills (chironomid). Thirteen taxa comprised over10 % in June, whereas, only 8 did so in September. Cycla.~pis variam' wasthe only taxon comprising at least 10 % in September and not in June.

The shore stations on each transect had the highest densities and speciesrichness in June (Table 2). In September the mid channel stations had thehighest densities and species richness, except at Transect 4 (Table 10).

Species richness and densities were always highest at the Transect stationsthan at the Oxbow stations (Tables 23 and 24). Transect 5 had the highestnumber of taxa (34 in June and 27 in September). Polychaetes and bivalveswere the most species rich groups at that transect, with amphipods andmysids also contributing to the high richness (Table 4). All taxa weremesohaline. The majority of taxa at the remaining Transects weregenerally more oligohaline (tables 2 and 3).

18

Transects 2 , 3, and 4 were predominated by polychaetes (primarilyLaeonereiscrdver;and'Streblo!!>pio benedicti) and bivalves (primarilyRangia Cllneata and Polymesoda caroliniana) with Mytilopsis lellcophaetaalso present on Transects 3 and 4.

Transects I and 2 had very diverse chironomid communities, although noone taxon contributed to more than 3 % of the fauna in June or Septemberat Transect 2, Proc!adilfs was the second most abundant taxon at Transect1 in June. Two annelids (Tlfbificoides heterochaetlfs and Laeonereisclflveri) contributed in excess of 50 % of the faunal community at Transect1 in September.

Oxbows-core samples

Forty taxa were collected at all Oxbow stations throughout the study(Table 19), compared with 70 at the Transect stations. The total taxa forthe combined Oxbow and Transect stations was 90 (Table 20).Chironomids and oligochaetes were the most diverse taxa overall (19 and17 respectively) and principally collected at the Oxbow stations. Thesegroups were followed closely by polychaetes and bivalves (12 and 11 taxarespectively) which primarily occurred at the Transect stations.

Chironomidae was the most diverse group at the Oxbow stations (16 taxa),with oligochaetes being the second (10). All other major groups wererepresented by one taxon, except bivalves with 3 taxa. With fewexceptions, all taxa are considered freshwater. Only five taxa collected areconsidered oligohaline, and, with the exception of Rangia cuneata, wererarely encountered: Streblo.~pio benedicti, Mytilopsis lellcophaeta,Bowmaniella sp., and Cyathllra polita. Of these, only Rangia wascollected at all stations. The remainder were only collected at Station 1,except for a single occurrence ofMytilopsis at Station 3, indicating apossible periodic saline intrusion.

Thirty-two taxa were collected at all Oxbow stations combined in June(Table 7), and 24 in September (Table 15). Chironomidae was the mostdiverse taxon in June (15), followed by oligochaetes (7). Both groupswere equally diverse in September, with only eight taxa.

Of the 40 taxa encountered, only six composed 10% or more of thecommunity throughout the study: Alilodrillfs pigueti and Stephensonianatrivandrana (oligochaetes), Rangia Clfneata (bivalve), and ChironOl17lfSand Proc!adilfs (chironomids). All six taxa composed in excess of 10 % in

19

June, whereas, only Au/odrius and Rangia did so in September.

Au/odri/us pigueti was the predominant oligochaete at all stations, andgenerally, the predominant taxon for both sampling periods except Staion 3in June. In September it comprised between 43 and 82 % of thecommunity at all stations. The remaining taxa were relativelyhomogeneous throughout the study area.

Species richness was fairly uniform at all stations in June, ranging from ISto 18 taxa (Tables 23 and 24). However, richness was more variable inSeptember, ranging from 7 taxa at Station 5 to 18 at Station I.

Faunal density was considerably higher in June, ranging from 113organisms at Station 4 to 905 organisms at Station I. The density wasmore consistent in September, ranging from 118 individuals betweenStations 1 and 4, but only 34 at Station 5.

No clear trends could be discerned between upstream, middle, anddownstream stations at each site.

Oxbows-qualitative

Qualitative samples were collected along the shoreline vegetation at eachsite to provide a more comprehensive evaluation of the communitystructure.

Ninety-three taxa were collected between all cores and qualitative samples.Forty taxa were collected in the core samples and 79 taxa were collectedfrom the qualitative samples (Table 21). Twenty-six taxa were sharedbetween the cores and the qualitative samples, primarily chironomids.Fourteen taxa were unique to the cores, primarily oligochaetes. Fifty-threetaxa were unique to the qualitative samples, primarily oligochaetes,gastropods and crustaceans. Chironomids and oligochaetes were the mostdiverse groups with 25 and 16 taxa respectively. Gastropods andcrustaceans (primarily isopods, amphipods and decapods) were the secondmost diverse groups with 7 and 15 taxa respectively. Although themajority of chironomids were common to both cores and qualitativesamples, II of the 16 oligochaete taxa \vere unique to the qualitativesamples. Only one of the seven gastropods collected was shared with thecores, and two of the 15 crustaceans were common to both.

Fifty-two taxa were collected in June (Table 9), and 61 in September

20

(Table 17). During each sampling period, Chironomidae was the mostdiverse group with IT taxa in June and 20 in September. At all stationsthree genera of chironomids usually comprised the majority of the fauna:TanytarsllS, Dicrotendipes, and Cladotanytarslls (Tables 8 and 16).

Crustacea was the next most diverse group with five isopods, fouramphipods, three decapods, and cumaceans, mysids, and Cirripedia eachwith one taxon. Oligochaeta was the third most diverse group with II taxacollected in June and lOin September. Dero was usually the most abundantoligochaete throughout the oxbow stations. Although gastropods wereonly represented by one taxon in June, Hydrobiidae, they were the thirdmost diverse fauna in September with seven taxa.

SUMMARY

1. The primary objective of this study was to establish baseline benthic dataon the tidal Caloosahatchee River to determine the potential rate ofrecovery on the benthic communities from the restoration of oxbows fromLake Okeechobee to the Franklin Lock.

2. The study area extended from the mouth of the Caloosahatchee Riverupstream to Franklin Lock. Five transects were established from ShellPoint to Beautiful Island on the lower half of the River. Three stationswere established on each transect: a shoreline station associated with apreviously revegetated site; a station immediately adjacent to the channel~

and a station located midway between the two. Five Oxbows weresampled from Beautiful Island to Franklin Lock. Three stations wereestablished at each oxbow: one at the upstream mouth of the oxbow; oneat the downstream end; and one in the middle. Samples were collected bydiver core at all stations. Qualitative samples were collected along theshoreline vegetation at each oxbow. Samples were collected associatedwith the dry season in June and the wet season in September of 1998.

3. One hundred thirty-six taxa within five phyla were collected. Seventy taxawere collected at the transects. Forty taxa were collected by core at theoxbow stations and 79 were collective in the qualitative samples. A totalof 93 taxa were collected by both methods at the oxbows.

4. Transect stations were dominated by polychaetes and bivalves. Fauna atTr:msect 5, near the mouth of the River, was considered mesohaline andthe most diverse. The fauna at the remaining transects was consideredoligohaline. The polychaetes, Strehlo!)pio henedicti and Laeonereis clliveri,

21

and the bivalves, Rangia cuneata and Polymesoda caroliniana were thepredominant taxa. Shore stations had the highest faunal densities andspecies richness in June. Middle stations generally had the highest densitiesand richness in September. Fourteen taxa comprised over 10 % of thefauna throughout the study.

5. The oxbow stations were dominated chironomids and oligochaetes. Thefauna at all stations was considered freshwater. An occassional oligohainetaxon was present at Oxbow 1, the downstream most site. The brackishwater clam, Rangia cuneata, was present at all stations. The predominantchironomids in the core samples were Chironomus and Procladius.Dicrotendipes, Tanytarsus, and Cladotanytarsus were the predominantchironomids in the qualitative samples. Aulodrilus pigueti was thepredominant oligochaete in the cores, and frequently the most abundantorganism at each station. Dero was usually the most abundant oligochaetein the qualitative samples. Six taxa comprised in excess of 10% of thefauna throughout the study.

6. Based on this study, the salinity influence on the benthic fauna extendedupstream to at least Beautiful Island immediately west of the 1-75 bridgewhere the fauna was still considered to be oligohaline. Immediately east ofthe 1-75 bridge the fauna was considered to be freshwater with a rareoccurrence of an oligohaline organism.

7. The reestablishment of oxbows may alter the water flow downstream of theFranklin Lock which may affect the salinity regime of the River. Thealteration of the salinity pattern would reestablish the boundary of thefreshwater-oligohaline benthic fauna. Consequently, the resultant changewould result in the migration and recolonization of benthic communities.Continuance of benthic monitoring during reconstruction of upstreamoxbows is recommended to determine any deleterious or beneficial effectson the downstream benthic fauna.
