Self-learning growth simulator for modelling forest stand dynamics in changing conditions [PDF]

, 2021
Finnish forest structures vary from even-aged planted forests to two- and multi-storied mixed stands. Also, the range of silvicultural systems in use has increased because thinning from above and continuous cover management are gaining popularity.

Carbon dynamics of Western North American boreal forests in response to stand-replacing disturbances

International Journal of Applied Earth Observations and Geoinformation, 2023
North American boreal forests are known to be an important carbon pool in boreal ecosystems, but have experienced extensive tree mortality and carbon loss due to multiple agents of stand-replacing disturbances in recent decades.

Interesting times on Krakatau: stand dynamics in the 1990s [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1999
The Krakatau Islands, Indonesia, have provided an opportunity for ecologists to track primary succession from the ‘clean slate’ of 1883, through forest closure in the 1920s, to the contemporary period, in which successional changes take the form of alterations in composition and stature of forest stands rather than gross changes in ecosystem type.
