experiment |
Type of experiment the wood fall was deployed for.
Site 1-Site 4 refer to the experiments testing 12 woodfalls each of Pinus elliotti and Celtis laevigata varying from small to large total weights.
aor refers to experiments testing abundance occupancy relationships (two deployments of 12 small and 12 large wood falls).
wood_type refers to an experiment testing 11 species of wood species on community composition with each species represented by four wood fall sizes.
net_nonet refers to an experiment testing the effects of the mesh wrap and lack of mesh wrap on the wood falls.
surf_area deploys woodfalls with wood-fall weight controlled but of varying surface area.
shallow is used to designate any wood fall deployed 50m and shallower.
