Abstract

This DRYAD data set covers statistical analysis for the study, "Seagrass restoration experiment to support coastal protection." 

Dataset attached covers row data regarding field experiments carried out to demonstrate the time needed for the seagrass to recover after disturbance (imitation of anthropogenic impact). The data is centered on showing the evolution (increase) of seagrass shoot density after a quantified period (time series over a year) where the pressure to seagrass is halted. Halting of pressure would resemble a total ban or reduction of anthropogenic impact of digging and revolving of seagrass; action carried out by communities, aiming to collect clams and other shellfish. This data covers also variation in sediments and epiphytes. 

Additional data is provided on the seagrass restoration methodology that was added to the above-mentioned experiment. The IUCN Red listed Vulnerable seagrass species, Zostera capensis was tested using the plug method (a sediment-based methodology). Two size plugs, made of PVC tube, were tested: 4.5 cm and 7.5 cm diameter size, over a 12-month period (measurements carried out on four occasions).  The 7.5 PVC tube experiment revealed a higher survival rate and is therefore a more suitable method for future Z. capensis restoration in impacted areas.

These data can be re-used as long as it cites the original data (this paper). To comply with best practices, we recommend mentioning the source of the data.

Methods

Field experiment was carried out within intertidal areas.  Control was also set ithin intertidal area. Data processing followed the use of ANOVA (two-factorial and one-way).
