Methods

Sampling method: Monitoring plot establishment and resampling exercises are conducted either at the end of the wet season period to facilitate flora identification (i.e. before herbaceous plants wither, or the vegetation is burnt), or late dry season due to access logistical restictions, for example floodplain sites. Sampling is designed to assess all levels of habitat strata including non-woody and woody species diversity. The overall plot size is 40 x 20 metre. The plot is permanently located by a central metal star picket and GPS waypoint. Plots relocated by helicopter have a round large white lid on top to assist sighting the plot from air. A permanent photo picket with number plate is placed 10 metre inside the plot parallel with the plot sides. The corners and inner transects are marked by metal droppers. The inner 40 x 10 metre plot is delineated with measuring tapes. Two 50 metre tapes are laid out 5 metres either side of the central photo picket, parallel to the longer central axis, starting at zero on the left hand side heading to the back of the plot, again at zero on the right hand side heading to the top of the plot. Nb: some plots are not strictly 40 metres long due to plot landscape constraints. A woody shrub is a woody species with DBH less than 5cm. • All Woody shrub individuals are counted in 3 height classes: < 50 cm; 50 cm - 2 m; > 2 m DBH. • Counts of individuals by species height < 50 cm class are undertaken along 1 m wide transects that define the ground stratum quadrats for the length of the plot. • Use 1 metre poles to measure the 1 x 1 metre quadrats along the length of the tapes along the inside of the tape. • For consistency shrubs in the < 50 cm height class should only be recorded along the entire 1 m transects defining the ground stratum quadrats. • Counts of individuals of each species height 50cm-2m and >2m are undertaken in the internal area of the plot equivalent to 40 x 10 m. Instrument Tape measure or measuring stick (height measurement)
