Identifying Old-Growth Forests in Complex Landscapes: A New LiDAR-Based Estimation Framework and Conservation Implications

open access: yesRemote Sensing, 2023
Old-growth forests provide many ecosystem services and benefits. However, they are becoming increasingly rare and thus are an urgent priority for conservation. Accurately mapping old-growth forests is a critical step in this process. Here, we used LiDAR,

Old-growth forests in the Pollino National Park (southern Italy): current status and future perspectives

open access: yesForest@, 2023
Old-growth forests have a primary environmental and ecological value, as they closely recall primeval forests and the natural forest landscape that was spread throughout Italy and Europe before man intervention heavily altered the functioning of most ...

Defining Old Growth for Fire-adapted Forests of the Western United States

open access: yesEcology and Society, 2007
There are varying definitions of old-growth forests because of differences in environment and differing fire influence across the Intermountain West. Two general types of forests reflect the role of fire: 1) forests shaped by natural changes in structure

Old-growth forest carbon sinks overestimated

open access: yesNature, 2021
Luyssaert et al.1 reported that unmanaged, old-growth forests continue to sequester atmospheric carbon (C) at a rate of 2.4 ± 0.8 Mg C ha–1 yr–1 for stand ages exceeding 200 years. This claim was based on an analysis of net ecosystem productivity (NEP) and other C flux data from temperate or boreal forest plots compiled from published studies and ...

Tight relationships between leaf and topsoil stoichiometries after 42 years of forest conversion from old-growth forests to Chinese fir plantations

open access: yesFrontiers in Forests and Global Change, 2023
Soil C:N:P stoichiometry can regulate plant survival and reflect soil fertility and nutrient utilization. Despite the widespread conversion of old-growth forests to plantations or secondary forests, there is little knowledge about how these conversions ...

Fonte Novello old-growth forest

open access: yesL'Italia Forestale e Montana, 2010
The study has been carried-out to compare the genetic diversity between old growth beech forest and post-harvested naturally regenerated stands. The purpose was also the evaluation of the possible genetic impact of harvesting systems; these information are needed for the development sustainable silvicultural methods.

Increase of an introduced bird competitor in old-growth forest associated with restoration [PDF]

open access: yes, 2012
Many successful invasions involve long initial periods in which the invader exists at low densities followed by sudden population increases. The reasons for such time-lags remain poorly understood.

A culture of conservation: How an ancient forest plantation turned into an old‐growth forest reserve – The story of the Wamulin forest

open access: yesPeople and Nature, 2021
The global expansion of forest plantations at the expense of natural forests, especially old‐growth forests, raises concerns about habitat loss and a decline in ecosystem services.

Dynamic old-growth forests? A case study of boreal black spruce forest bryophytes

open access: yesSilva Fennica, 2011
Old-growth forests have sparked significant interest over the last twenty years and definitions have evolved from structure based to process based, acknowledging the diversity of forests that could be considered old growth.

The roles of plant pathogens in old-growth forests

open access: yesBucovina Forestieră, 2022
Old-growth forests are considered a benchmark for naturalness and models to which one compares managed forests, comparison leading to debates around biodiversity and its conservation, structure and dynamics, polarizing conservationists and forest ...
