At the same time they act as sources through deforestation and degradation, as well as sinks through forestation and possibly enhanced growth.
Trees have widely differing responses to temperature.
Although the effects of climate change on biodiversity are still poorly understood, many weather anticipate a significant loss of species due to climate change due to its permanency. Land use change is obviously the greatest threat to species diversity of tropical forests. The C pool in durable wood products can be increased by expanding demand for wood products at a faster rate than the decay of wood products.
