Abstract:	Marsh plant species frequency of occurrence along marsh transects for Rowley River tidal creeks associated with long term fertilization experiments, Rowley and Ipswich, MA. The TIDE project aims to simulate eutrophication on a large scale by the addition of NO3- aiming to reach 70µM concentrations from May to September every year during the growing season. This fertilization of the marsh has been going on at Sweeney Creek since the 2004 growing season through 2011 and at Clubhead Creek in 2005 and from 2009 till 2011.

TAXONOMIC COVERAGE:
Taxonomic Protocols
Organisms studied	Spartina alterniflora, Distichlis spicata, Spartina patens, Juncus gerardii, Triglochin maritima, Atroplex patula, Salicornia depressa, Limonium carolinianum, Iva frutescens

Methods:	Frequency of species by transects examines the number of 1 m2 quadrats along a ~50 meter transect where an individual species is present. These transects were sampled every year between 2003-2009 and in 2011. Mean values per quadrat were derieved for average transect frequency. Abbreviations: TSA- Spartina alterniflora (tall form) SSA- Spartina alterniflora (short form) DS- Distichlis spicata SP- Spartina patens JG- Juncus gerardii TM- Triglochin maritima AP- Atroplex patula SD- Salicornia depressa LC- Limonium carolinianum IF- Iva frutescens Water- Water in quadrat Mud- Mud in quadrat Dead- Dead in quadrat Creeks- Reference creeks are West (WE) and Nelson(NE) Nutrient Enriched creeks are Sweeney (SW) and Clubhead(CL). Sweeney has been fertilized every summer from 2004-2011. Clubhead had been fertilized in 2005 and then from 2009-2011. All creeks have two branches determined by direction at confluence while facing upstream (Left or Right). Plant transects run perpendicular to creeks at various points with a front pole at the creek bank and a back pole an the high marsh. Transects are in the order of 1, 2, 4, 3 or blue, green, red, yellow from confluence of branch.
