full name of the dataset:
Seasonal floodplain herbaceous plant species in the Okavango Delta, Botswana
dataset short name:
Boro and Xudum Floodplain Vegetation Data 2007
type of dataset (more information):

specify:
1 sq m quadrats along transects across 30 sites
data type:
point data/observation data
short description of the dataset/summary:
This study covered the southern parts of the Okavango Delta - the seasonally flooded Xudum and Boro distributary systems. It was a single campaign aimed at collecting and analysing floodplain vegetation species and abundance data, to establish relationships with hydroperiod for exploratory scenario modelling. A stratified random sample of 30 sites was surveyed for species composition and abundance between mid-March and mid-July 2007, using multiple 1 sq m quadrats along transects orthogonal to the floodplain long axis. Minimum sampled area at each site was 30 sq m. Hydroperiod was established based on three sets of remote sensing data: 1:50,000 analogue aerial photography from 2001, Landsat (annual) and MODIS (monthly) data from 2000-2007, and ground truthing from 2007.

specification of method(s) used for sampling and sorting:
- Step 1 involved the selection of random sites for vegetation sampling. This was based on historic hydroperiod - a flood frequency map derived from remote sensing which assigned a frequency to each pixel. The frequency map was stratified into 5 strata of approximately equal area, and in each stratum 6 sites were selected by randomising the pixel numbers. - Step 2 involved doing surveys of the vegetation at each site by laying out transects orthogonal to the long axis of each floodplain, and enumerating plant species within 1 square metre quadrats at 20 metre intervals along these transects. Species-area plots from sampling carried out beforehand indicated that a minimum of 25 square metres should be sampled. A minimum of 30 quadrats was thus surveyed at each site. All species in each quadrat were recorded and their relative abundance estimated according to a modified Braun-Blanquet classification.

sample type (e.g. habitat specific samples, composite samples etc.):
Quadrats were sampled along transects which crossed the topographic gradients of each floodplain site. That is, they were designed to sample all microhabitats within each floodplain site.
specific sample location (e.g. littoral, profundal, transect, shoreline, hyporheic zone, etc.):
Multiple transects per site.

availability of maps:
no
quality control procedures:
Were any quality control procedures applied to your dataset?
yes
quality control protocols and comments:
Relative abundance estimates were made by consensus of at least two field surveyors, and a one-day calibration exercise was carried out at the beginning of the field work to ensure consistency. Data entry was done by M. Murray-Hudson, and F. Murray-Hudson into a custom-designed Microsoft Access relational database; reading of field sheets and typing was done alternately, and data were cross-checked with field sheets after all had been transcribed.
