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. Trees are defined as any woody species with diameter at breast height (DBH) > 5cm. • All stems occurring within the whole plot are labelled with numbered metal tags and identified by species. • Only one tag is required per tree, not per stem. Multi-stemmed trees will have more than one DBH per tree. • The canopy top height in metres of each tree is estimated visually or with a clinometer. • Scarring from fires is recorded on a scale of 0 to 5, referring to (in increasing severity) no scarring; charcoal on surface of bark only; scarring damage to cambium; scarring on trunk over large area; severe scarring on trunk over large area likely to result in death; dead. Fire scars are recorded only once per tree. • DBH is measured for each separate stem that has ? 5 cm DBH. DBH is the vertical height measured at 1.3 metres from the level of the base of the tree. DBH is measured using a diameter tape or calipers. *Note: Due to logistical constraints there is some variation in size of plots.
