Tree distributions across continents indicate three distinct stable states in tree cover―forest, savanna, and treeless. It has been suggested that tropical forest and savanna could represent alternative stable states, implying critical transitions at tipping points in response to altered climate or other drivers. So far, evidence for this idea has remained elusive, and integrated climate models assume smooth vegetation responses. We analyzed data on the distribution of tree cover in Africa… 

Growing aridity and seasonality can drive catastrophic changes in the Amazon forest

The consolidation of a non-analogous climate shortly will likely affect the structure and functioning of Amazon, the most biodiverse terrestrial ecosystem on the planet. However, the ecological

Floristic evidence for alternative biome states in tropical Africa

An alternative approach to delimit the climatic envelope of the two biomes in Africa using tree species lists gathered for a large number of forest and savanna sites distributed across the continent, supporting the alternative stable states hypothesis for Africa and corroborated by paleoecological evidence.

Tree Cover Bimodality in Savannas and Forests Emerging from the Switching between Two Fire Dynamics

This work shows, using a simple matrix model of tree dynamics, how the bimodality of tree cover can emerge from the switching between two linear dynamics of trees, one in presence and one in absence of fire, with a feedback between fire and trees.

Fire drives functional thresholds on the savanna-forest transition.

The results are consistent with the hypothesis that forests and savannas are two coexisting stable states with contrasting patterns of function and diversity that are regulated by fire-plant feedbacks and shed light on the mechanism driving each state.

The absence of alternative stable states in vegetation cover of northeastern India

Globally, forests and savannah are shown to be alternative stable states for intermediate rainfall regimes. This has implications for how these ecosystems respond to changing rainfall conditions.

Resilience and Alternative Stable States of Tropical Forest Landscapes under Shifting Cultivation Regimes

It is suggested that maximization of short-term agricultural output may have counterproductive impacts on the long-term productivity of shifting cultivation landscapes and the persistence of forested areas.

Analysis of stable states in global savannas: is the CART pulling the horse?

It is shown how classification and regression tree (CART)-based products may impose discontinuities in satellite tree-cover estimates even when such discontinUities are not present in reality.

Dispersal increases the resilience of tropical savanna and forest distributions

This work examines the contributions of dispersal to determining savanna and forest distributions using a reaction-diffusion model, and suggests that both models are limited in that they ignore spatial processes, such as dispersal.

Tipping points in tropical tree cover: linking theory to data

This work presents a simple dynamical model that can generate three alternative tree cover states (forest, savanna, and a treeless state), based on known mechanisms, and uses this model to simulate patterns of tree cover under different scenarios to show that the hysteresis inferred from remotely sensed tree cover patterns will be inflated by spatial heterogeneity of environmental conditions.

Determinants of woody cover in African savannas

It is shown, using data from 854 sites across Africa, that maximum woody cover in savannas receiving a mean annual precipitation (MAP) of less than ∼650 mm is constrained by, and increases linearly with, MAP.

Alternative stable states in Australia’s Wet Tropics: a theoretical framework for the field data and a field-case for the theory

The vegetation of the Wet Tropics bioregion of Far North Queensland is a complex system whose components (mainly tropical rainforests and fire-prone forests and woodlands) have mostly been studied

What Limits Trees in C4 Grasslands and Savannas

The extent of this climate mismatch has been revealed by physiologically based global vegetation simulations and by large empirical data sets, and the implication is that ecosystem structure and function depend on demographic transitions.

Savannas are inherently “disturbed” ecosystems, but the regularly recurring disruptions play such a fundamental ecological role (Scholes and Archer, 1997) that “episodic events” rather than

El Niño as a Window of Opportunity for the Restoration of Degraded Arid Ecosystems

Most arid ecosystems have suffered from severe overexploitation by excessive wood harvesting, overgrazing, and agriculture, resulting in depletion of vegetation biomass and soil erosion. These

Tree cover in sub-Saharan Africa: rainfall and fire constrain forest and savanna as alternative stable states.

This model demonstrates that, given relatively conservative and empirically supported assumptions about the establishment of trees in savannas, alternative stable states for the same set of environmental conditions are possible via a fire feedback mechanism and could improve the ability to predict changes in biome distributions and in carbon storage under climate and global change scenarios.

Long-term forest–savannah dynamics in the Bolivian Amazon: implications for conservation

The aim of this paper is to evaluate the respective roles of past changes in climate, geomorphology and human activities in shaping the present-day forest–savannah mosaic of the Bolivian Amazon, and

Interactions among Amazon land use, forests and climate: prospects for a near-term forest tipping point

Several important trends could prevent a near-term forest dieback as fire-sensitive investments accumulate in the landscape, property holders use less fire and invest more in fire control, and emerging carbon market incentives for reductions in deforestation could support these trends.

Effects of four decades of fire manipulation on woody vegetation structure in Savanna.

Evidence is provided that savannas are demographically resilient to fire, but structurally responsive, and the density of woody individuals was unresponsive to fire.
