A 35-year controlled burning experiment in Minnesota oak savanna showed that fire frequency had a great impact on ecosystem carbon (C) stores, with most carbon stored in woody biomass.Abstract:
A 35-year controlled burning experiment in Minnesota oak savanna showed that fire frequency had a great impact on ecosystem carbon (C) stores. Specifically, compared to the historical fire regime, fire suppression led to an average of 1.8 Mg·ha−1·yr−1 of C storage, with most carbon stored in woody biomass. Forest floor carbon stores were also significantly impacted by fire frequency, but there were no detectable effects of fire suppression on carbon in soil and fine roots combined, or in woody debris. Total ecosystem C stores averaged ∼110 Mg/ha in stands experiencing presettlement fire frequencies, but ∼220 Mg/ha in stands experiencing fire suppression. If comparable rates of C storage were to occur in other ecosystems in response to the current extent of fire suppression in the United States, fire suppression in the USA might account for 8–20% of missing global carbon.read more

Land-use legacies of twentieth-century forestry in the UK: a perspective
TL;DR: In this article, a review of the dynamics of forest landscapes in the UK over the last 100 years, shows that certain decisions, policies and management activities had major effects on the landscape, especially in terms of landscape patterns and species distribution.

Carbon sequestration in Mediterranean ecosystems: critical aspects related to plant respiration, wildfires and nitrogen budget
Victoriano Ramón Vallejo Calzada,Isabel Fleck i Bou,Joaquim Azcón-Bieto,Pere Rovira i Castellà +3 more
TL;DR: In this paper, the authors present a model for Mediterranean terrestrial ecosystems, in which drought is expected to increase in the future as a result of climate change in boreal and tropical forests.

On the carbon dynamics of Australian subalpine grasslands
TL;DR: In this article, the effects of differences in climate on carbon balance in subalpine grassland ecosystems were investigated at two climatologically contrasting sites during 2007/08: a cooler, wetter site that sustains winter snow cover (Dargo), and a warmer, drier site that does not (Nimmo).

TL;DR: Slowing deforestation, combined with an increase in forestation and other management measures to improve forest ecosystem productivity, could conserve or sequester significant quantities of carbon.

Terrestrial ecosystems and the carbon cycle
TL;DR: The terrestrial biosphere plays an important role in the global carbon cycle as mentioned in this paper, which is the fluxes of carbon among four main reservoirs: fossil carbon, the atmosphere, the oceans, and the terrestrial Biosphere.

TL;DR: The first edition of Schlesinger's Biogeochemistry in 1991 was an early entry in the field of Earth system science/global change, and has since gained sufficient popularity and demand to merit a second, extensively revised edition.

The U.S. Carbon Budget: Contributions from Land-Use Change
TL;DR: The rates at which lands in the United States were cleared for agriculture, abandoned, harvested for wood, and burned were reconstructed from historical data for the period 1700-1990 and used in a terrestrial carbon model to calculate annual changes in the amount of carbon stored in terrestrial ecosystems, including wood products.
