The Convention on the Trade in Endangered Species (Cites) summit on Thursday placed all 300 species of rosewood under trade restrictions, meaning criminals can no longer pass off illegally logged species as legitimate.
We used a field survey to examine the potential drivers (forest structure, flooding and anthropogenic disturbance e.g. grazing and logging) of species richness and composition of Eucalyptus camaldulensis floodplain forests in southeastern Australia.
Notably, the oldest species, such as the lesser tree shrew and the banded civet--all of whom came on the scene during the Miocene Epoch 23.9 million to 5.3 million years ago--were much more sensitive to logging than species that appeared more recently, such as the Asian elephant and the long-tailed macaque.
Log species, bark cover and diameter showed more limited influence on community composition in this study.
For each log, we calculated mean diameter from the previously described seven measurements, and recorded log species (birch or spruce), presence/absence of branches and tops.
Upon the recommendation of referee Patrick Tobin, we have provided additional data that shows the relationship between log (species richness) and log (forest area).
Regression of log (species richness + 1) versus log (forest area + 1) indicated a strong linear relationship between cerambycid species richness and forest size (R = 0.80).
In comparison, the break-even carbon price was much less sensitive to logging damage, species-specific growth rates and mortality rates, and to the initial tree densities by species and diameter class (Figure 3A and Additional file 1).

The highest number of the medicinal plant species (55) occurred in old-growth forest, 40 species grew in forest degraded by logging, and 49 species grew under regrowth forest.
Its "citizen scientists" logged common species, and also found creatures previously undetected in the area.
