I started thinking about this because of two comments from recent conservation discussions. In the first planting was argued to be less desirable than natural regeneration because ‘unnaturally high densities’ of trees were being planted.

It is generally much more exciting for funders, and often for the researchers themselves, to set-up new… Continue reading How do we best organise studies of long-term change?
