Part One: Mollusk Surve '

Rapid- urvey meth d were employed fr m De ember 12, 2005 to February 10, 2006, to cen us the macro-mollusk communi tie of th An I t Ri ver, lorida. The Anclot Ri er wa ampled from it mouth to ri er ki lomet r (RK) .0 on on ki lometer interval · then on half ki lometer intervals t RK 12.0, and th n at RK 13, 14, and 15. A Distri ct RK map a u ed to 10 ate tat ion and al l ampled ite orre ponded to it defined by the

cope of Work, e cept that RK 11. was rno ed to RK 11.3 to avoid local human di turbance . Be au e RK 16 was not ampJed a per the Pur hase Order, a replacem nt effo rt was made at RK - 1.0.

Becau e the primary objecti e of the rudy was to identi fy down- tream pattern in p cie di per ion, amples were collected aero each tran ecl at representative sites,

and data were poo led for the en tire tran ecL In ingle-channel reache , ubtidal am ples wer collected clo e by opposite bank and at e enly paced intervals acros the channel. In reach s wi th mar hiland and mUltipl e channels, ubtidal effort was distributed 0 as to ample in each channel or bas in.

ollection of intertidal ample was biased by two criteria. Fir. t, accreting banks were preferred over eroding o ne , meani ng in practice that the in ide of bend were pr ferred o er out ide , and that ample were lIecled more from poi nt-bar mar h i land and hoals than from teepl incl ined banks. Second, a preference wa mad for the bank

j udged to be lea t altered b human activity. ea wall and fill ed area were avoided where po ible.

ubtidal ample MLW) were ollected by a petite ponar grab rather than pipe cor becau e larger mollu ks are often mi ed or I t by the core . Ponar grab offer a larg r ampling urface area (0.02 2 quare meter ) than pipe cores (0.00456 quare meter ). A ample was comprised of one ponar grab at a given location . Five su h ubtidal ample

were taken in di fferent en vironment along each hal f-kilometer tran ecl givi ng a pertran e t ampl ing urface area of 0. 11 6 quare meters. ontent of each ample were concentrated 0 er a 3.0 millimeter sie e and proce ed in the fie ld. n\mown were bagged and r turned t the Lab ratOl for identi fi cation.

Intertidal ample (> MLW u ually wer colle ted by pade although p nar grab were u ed in areas wh re the ub tratum a unfi t for wading. Intertidal effort as th am a ubtidal effort e cept that hand co ll ection f parti cular peci w r added to intertidal ample 0 a to record th pre en e of rare or cryptic specie . The ga tr pod 'i'.

The Anclote River fauna is comprised of many pecie that were represented by deadonly material, e en when An lote nchorage Fauna are di counted. De pite e tra effort to identify and cen or relict or fo il material, a few of the dead-only reports may repre ent ntamination of th modem fauna. The Andote Ri er we t of . . Highwa Alternate 19 has be n dredged extensivel , ex.po 'ing and spoiling much old material a ubtidal and intertidal fill , and a eroding poil island .

Compared to other outhwe t Florida rivers studied b similar method , An lot Ri er mollu k collection t nded to produce ma LI pecimen that occurred in low densitie and over horter reach of the river. Con idering these tendencies along with high pecie ri hne. , Anclote Ri er fauna may b shaped by constant but low levels of succe sful recruitment, Follo ed by 10\ growth or high mortality prior maturation. Rea on for mall molluk size densitie , and ranges are not e ident from the collected data.

Low den itie rnak interpretation of indi idual species data di fficult when 0 tI \ station were occupied. The introduced, naturalized and inva i e species orbiettla manili nsis was found as dead material at RK I 1.3, but may not occur in the ri er's up tream reach 0\ . ing to teep channel banks and unsuitable ediment c ndition at depth .

The subtidal clam Rallgia cuneata wa al 0 found at only one tation (RK 15.0) but i probably a table element of the fauna because it \ a collected as both Ii e and dead material and a very large pecimen . One live Rangia mea ured 76 mm and i the large t li ve Rangia pecimen collected to date in mollu k survey in outhwe t Florida. Mu el pecie that tend to occupy broad river reache el ewhere occur at one or twu tation in the Anclote River, and except for one pecie di cu sed below mu el are not

ad minant element of the An lote' s mollu can fauna.

Tage/u was pre ent a Ii e and dead material. Their hells are fragi le 0 it i reasonable to a ume that the material wa recent. Highe t densities were from RK 4.0-6.5 and large t Ii e and d ad hell were upstream fRK 5.0 (Figure I). Geukensia demi sa wa the on l mu eJ to occur in high den ity or occupy a sub tantiaJ reach of the ri er. Thi mostly intertidal pecies wa most abundant down tream but large t, upstream within it II kilometer reach igure 2 . Another intertidal pecie , Polymesoda caroliniana, wa ommon in the upper half of the tidal river and, like Tagelus, was mo t abundant

down tream but large t, up tream within its reach (Figur 3) .

y ter \ as encountered at I tation between the ri er mouth and RK 9.0, but their range and abundance i imperfectly de cribed b ampling on half or whole kilometer intervals. In general , mall and mostly dead oy ter reef: 0 ur at and near the ri er mouth and lower fev kilometer , but large li ve reef: are mo t conspicuou from RK 4.0 to RK 7.0. Reef: then become mailer and more wid \y spaced up tream t near RK 9.0. Intertidal oy ter were more common than ubtidal one and like the other intertidal pe ies, were mo t abundant down tream but large t. up tream wi thin its reach (Figure

4).


One p ie colle ted in ery high number wa not a mollu k but i rep rted her becau e it pre en orre ponded with a paucity 0 mollu k , and lik many clam , it is al 0 a filter-feed r. A oft tuni at in th Famil Molgulidae repre ent d about I percent of th t tal pecim n count. It w primaril ubtidal, only fi und aJi e, and ery abundant in off- hannel areas betw en RK 3.0 and .0 (Figure ).

changes characteri tic of rapid rate of communit tructure evolution. Th marine mmunity of Anclote Anchorage i di tin tive. Once within th ri er th lower river

down tream " ag" appear in p cie ri lme near RK 2.0 (Figur 8,9), and i evident in faunal den itie io the RK 1.0-3 .0 reach (Figures 10, II). Thi depre ion in di ver ity and den it i not regarded to be a property of th natural moHu k mmuni ty but rath r the effect of ever habitat limitation impo d by exten ive dredging and spoiling, and the effect of a high energy en ironment creat d by boat wake . On balan e, harp d lines in abundance from RK 4.0 t 5.0, and harp decline in di er ity from RK 5.0 to 6.0 are con id red to be the re ult of naturall occurring changes in communi ty tructure.

Remark

The Anclole Ri er pre en a di ver e fauna r lati ve to other tidal tern tudied by imilar method . The pre ent urve depict a fauna compri ed of many mall and often

dead p cim ns of many pecie , most of" hich occur in relati el short ri er rea he . pecie replacement rate are high a a fun ti n of ri er location (Figure 12 . An

authentk tidaJ river fauna occur in the An lote Ri er, primarily from RK 7. to RK 11 .. It is bracketed by a down tream estuarin and an up tream oligohaline fauna. An apparent ' sag" in down tream richen s and den ity i on idered to be th on equence of habitat con traint . The con traiojng effect f tuni ate comp tition, heavy algal a umuJati n at orne tati on , and poor edi ment probably a count for orne f the pattern ob erv d in Anclol mo llu k fauna, pecially in off-channel and back-ba area . Dynami mean , ranges, and extreme of alini ty along the tidal river may also contribut to the ob rved re ult though no alinity data were collect d in th pres nt effi rt . fi'.

Part Two: horeline Mapping

A "wind hield" u e of the Anclol River to identify change !break in horeline typ a conducted during January 2006. The urvey \Va condu ted from a small boat. All

horeline as ociated with the main channel ( igur I) of the ri er including island and ba ou horeline were included in th urvey. hange !break in horeline type were patially regi tered using a W AA -enabled GP and phot graph d digitall . Logi ti

Field data were used to create a GI hapefi le depicting the ri er' horeline with segment d fined b typ (e.g. mangro e) u ing the appropriate FLU cod (Table - 4). Segment defin iti ns were de eloped to repre ent a minimum of 9 % of the visible horeline as e n from th urv boat - for example, medium den ity re idential area

with singl story uni ts (12 1 I) with a narro\ fringe of mangro e tre ar defined a 12 11 n t a mangro e swamp (612).

ach horeline egment was cia sifi ed at F Level I through 4 a depicted in igures 2 through S wi th clas ification ba ed on a compilation of the urvey data and

data (e.g. horeline position) extra ted from the Oi trict 2004 ( I :24000) natural color aerial photograph . After completing this exercise, the ri er wa split into additional egments defined b river ki lometer and shoreline po ilion ( orth or outh) (Figure 6)

using data provided by the District (Figure 7). Till shapefil e w u ed to categoriz each horeline egment b river ki lom t rand horeline p ition (Figure 8). ote that ri er

kilometer polygons are not of equal ize because of the si nuo ity of the river. Thi caveat i al true for the amount of horelin contained in th mailer horeline po ition p I gon created (F igure 9). Difference in the proportion of shoreline by river ki lometer and horel ine positi on are illustrated in Figure 10.
